2. Modern Money Mechanics
Thepurpose ofthisbookletis to desmmbethe basic
process ofmoneycreation in a ~actionalreserve"bank-
ingsystem. l7zeapproachtaken illustratesthe changes
in bank balancesheets that occurwhen depositsin banks
changeasa result ofmonetaryactionby theFederal
Reserve System-the centralbank ofthe UnitedStates.
Therelationshipsshown are based onsimplil5ring
assumptions. For thesake ofsimplicity,the relationships
areshown as iftheywere mechanical,but theyare not,
as isdescribed laterin the booklet. Thus,theyshould not
be intwreted to implya closeandpredictable relation-
ship betweena specificcentral bank transactionand
the quantityofmoney.
Theintroductorypages containa briefgeneral
desm'ptionofthe characte*ics ofmoneyand how the
US. moneysystem works. m e illustrationsin thefbl-
lowingtwosections describe twoprocesses: fijirst, how
bank akposits expand orcontractin responsetochanges
in theamountofreservessupplied by thecentml bank;
and second, how thosereservesareafected by both
FederalReserve actionsand otherjizctm. Afinal sec-
tion deals withsome ofthe elementsthat modifi,at least
i~theshort Tun,thesimple mechanical relationship
between bank reservesand depositmoney.
Moneyis sucha routinepart of everydaylivingthat
itsexistenceand acceptanceordinarilyare taken forgrant-
ed. A user may sensethat money must comeinto being
either automaticallyasa resultof economicactivityor as
an outgrowth of somegovernmentoperation. Butjust how
this happens alltoo often remainsa mystery.
What Is Money?
If moneyisviewed simplyasa tool used to facilitate
transactions,onlythose media that are readily acceptedin
exchangeforgoods,services,and otherassetsneed to be
considered. Manythings-from stonesto baseballcards
-have servedthis monetaryfunctionthrough the ages.
Today,in the United States,money used in transactionsis
mainly of threekinds-currency (papermoney and coins
in the pocketsand purses of the public);demand deposits
(non-interest-bearingcheckingaccountsinbanks);and
othercheckabledeposits,such asnegotiableorderof
withdrawal (NOW)accounts,atalldepositoryinstitutions,
includingcommercialand savingsbanks, savingsandloan
associations,andcreditunions. Travelerschecksalso are
included in the definition of transactionsmoney. Since$1
in currencyand $1in checkabledeposits arefreelycon-
vertible intoeach otherand both canbe used directlyfor
expenditures,they are moneyin equaldegree. However,
onlythe cash and balances held by the nonbank public are
countedin the money supply. Depositsof the U.S. Trea-
sury,depositoryinstitutions,foreignbanksand official
institutions,aswell asvault cash in depositoryinstitutions
areexcluded.
Thistransactionsconceptof money is the onedesig-
nated asM1in the FederalReserve's money stock statis-
tics. Broaderconceptsof money (M2 and M3) includeM1
aswell ascertainotherhancial assets (such assavings
and time depositsatdepositoryinstitutionsand sharesin
moneymarket mutual funds) which are relativelyliquid
but believed to representprincipallyinvestmentsto their
holdersrather than mediaof exchange. While fundscan
be shiftedfairlyeasilybetween transaction balances and
these otherliquid assets,the moneycreationprocesstakes
placeprincipallythrough transaction accounts. In the
remainderof thisbooklet, "money"meansMI.
The distributionbetween the currencyand deposit
componentsof money dependslargelyonthe preferences
of the public. When a depositorcashesa checkor makes
a cashwithdrawal through an automaticteller machine,he
or shereducesthe amountof depositsand increasesthe
amountof currencyheld by the public. Conversely,when
people have morecurrencythan is needed, someisre-
turned to banks in exchangefor deposits.
While currencyisused for a greatvariety of small
transactions,most of the dollaramount of moneypay-
mentsin our economyare made by checkorby electronic
3. transferbetween depositaccounts. Moreover,currency
is a relatively smallpart of the moneystock. About 69
percent,or$623biion, of the $898 biion totalmoney
stockin December 1991,wasin the formof transaction
deposits,of which$290billion were demand and $333
billion were other checkabledeposits.
What Makes MoneyValuable?
In the United Statesneitherpaper currencynor
depositshavevalue ascommodities. Intrinsically,a dollar
bii isjust a pieceof paper, depositsmerelybook entries.
Coinsdo have someintrinsicvalue asmetal,but generally
farlessthan their facevalue.
What,then,makesthese instruments-checks,
paper money,and coins-acceptableatfacevalue in
payment of alldebtsandfor othermonetary uses? Mainly,
itisthe confidencepeoplehave that theywillbe ableto
exchangesuchmoneyfor otherfinancialassets and for
real goodsand serviceswhenever theychooseto do so.
Money,like anythingelse,derivesitsvaluefrom its
scarcity in relation to itsusefulness. Commoditiesor ser-
vices aremore orlessvaluablebecause there are more or
lessof them relative to the amountspeoplewant. Money's
usefulnessisitsunique abilityto commandothergoods
and servicesandto permit aholder to be constantlyready
to do so. How much money is demanded dependson
severalfactors,suchasthe totalvolumeof transactions
in the economyat anygiven time,the paymentshabits of
the society,the amount of moneythat individualsand
businesseswantto keep on hand to take care of unexpect-
ed transactions, and the foregoneearningsof holding
tinancialassetsin the form of moneyrather than some
other asset.
Control of the quantity of moneyisessentialif its
valueis to be kept stable. Money's real value canbe mea-
sured onlyin termsof what itwillbuy. Therefore,itsvalue
variesinverselywith the generallevelof prices. Assuming
a constant rate of use,if the volume of money growsmore
rapidlythan the rate atwhich the outputof realgoodsand
servicesincreases,priceswill rise. Thiswill happen b e
causetherewill be more money than therewillbe goods
and servicesto spend it on at prevailingprices. But if, on
the otherhand, growthin the supplyof money does not
keeppacewith the economy'scurrentproduction,then
priceswillfall,the nation's laborforce,factories,and other
production facilitieswillnot be fully employed,or both.
Just how largethe stockof moneyneeds to be in
ordertohandlethe transactionsof the economywithout
exertingundueiduence on the price level dependson
how intensivelymoney isb e i iused. Everytransaction
depositbalanceand everydollarbill isa part of some-
body's spendablefundsat anygiventime, ready to move
to otherownersastransactionstake place. Someholders
spend money quicklyaftertheyget it, makingthese funds
availablefor otheruses. Others,however,hold moneyfor
longerperiods. Obviously,when somemoney remains
idle,a largertotalis needed to accomplish anygiven
volume of transactions.
Who Creates Money?
Changesin the quantityof money may originatewith
actionsof the FederalReserve System (thecentralbank),
depositoryinstitutions (principallycommercialbanks),or
the public. The majorcontrol,however,rests with the
centralbank.
The actualprocessof money creation takesplace
primarilyin banks.' As noted earlier,checkableliabilities
of banksare money. These liabilitiesare customers'ac-
counts. Theyincreasewhen customersdepositcurrency
and checksandwhen the proceedsof loansmade by the
banksarecreditedtoborrowers' accounts.
In the absenceof legalreserve requirements,banks
canbuild up depositsby increasingloansand investments
solongastheykeepenoughcurrencyon hand to redeem
whatever amountsthe holders of depositswantto convert
intocurrency. Thisunique attributeof the bankingbusi-
nesswas discoveredmany centuriesago.
It startedwith goldsmiths. As earlybankers,they
initiallyprovided safekeepingservices,makinga profit from
vaultstoragefeesforgold and coinsdepositedwith them.
Peoplewould redeemtheir "depositreceipts"whenever
they needed gold orcoinsto purchase something,and
physicallytake the gold or coinsto the sellerwho,in turn,
would depositthem for safekeeping,oftenwith the same
banker. Everyone soonfoundthat itwasa loteasier simply
to use the deposit receiptsdirectlyasa meansof payment.
These receipts,which became known asnotes,were ac-
ceptableasmoney sincewhoeverheld them couldgo to
the banker and exchangethem for metallicmoney.
Then,bankers discoveredthat they could make loans
merelyby giving their promisesto pay, orbank notes, to
borrowers. In thisway,banksbegan to create money.
More notes couldbe issuedthan the gold and coinon hand
because only a portionof the notesoutstandingwould be
presented forpaymentat anyonetime. Enough metallic
moneyhad to be kept on hand, of course,to redeemwhat-
evervolumeof noteswas presented for payment.
Transactiondepositsare the modem counterpartof
bank notes. Itwas a small stepfromprintingnotesto mak-
ingbook entriescreditingdepositsof borrowers,which the
borrowersin turncould "spend"by writingchecks,thereby
"printing"their own money.
Inordertodescribethemoneycreationprocessassimplyaspossible,the
term Bank"used in this bookletshouldbe understoodto encompassall
depositoryinstitutions. SincetheDepositoryInstitutionsDeregulationand
MonetaryControlActof 1980,alldepositoryinstitutionshavebeenpermit-
ted to offer interest-bearing transaction accounts to certain customers.
Transaction accounts (interest-bearing as well as demand deposits on
which payment of interest is still legally prohibited) at all depository
institutions are subject to the reserve requirements set by the Federal
Reserve. Thus an such institutions, notjust commercialbanks,havethe
potential for creatingmoney.
4. What Iimits the Amount of Money Banks
Can Create?
If depositmoney canbe createdsoeasily,what isto
preventbanksfrommaking too much -more than sufti-
cient to keep the nation's productiveresourcesfullyem-
ployedwithoutprice inflation? Likeitspredecessor,the
modem bank must keep available,to makepayment on
demand,a considerableamountof currency andfundson
depositwith the centralbank. Thebank mustbe prepared
to convertdepositmoneyintocurrencyforthose deposi-
torswho requestcurrency. It must make remittanceon
checkswritten by depositorsand presented for payment
by otherbanks (settleadverseclearings). Finally,it must
maintain legallyrequired reserves,in theformof vaultcash
and/or balances atitsFederal ReserveBank,equalto a
prescribedpercentage of itsdeposits.
Thepublic's demandfor currencyvariesgreatly,but
generallyfollowsa seasonalpattern that isquitepredict-
able. Theeffectsonbank fundsof thesevariations in the
amountof currencyheld by the public usuallyareoffsetby
the centralbank, which replacesthe reservesabsorbedby
currencywithdrawalsfrombanks. Ousthowthisisdone
willbe explainedlater.) For allbankstaken together,there
isno net drainof fundsthroughclearings. Acheckdrawn
on onebank normallywillbe depositedto the creditof
anotheraccount,if not in the samebank, then in some
otherbank.
Theseoperatingneeds influencethe minimum
amountof reservesan individualbankwillhold voluntarily.
However, aslongasthis minimum amountislessthan
what islegallyrequired, operatingneeds areof relatively
minor importanceasa restrainton aggregatedepositex-
pansion in thebankingsystem. Such expansioncannot
continuebeyond the pointwherethe amountof reserves
that allbankshave isjust sufficientto satisfylegal require-
ments under our"fractionalreserve" system. For example,
if reservesof 20 percentwere required, depositscould
expand onlyuntiltheywere fivetimes aslargeasreserves.
Reservesof $10million could supportdepositsof $50mil-
lion. Thelowerthe percentage requirement,the greater
the depositexpansionthatcanbe supportedby eachaddi-
tional reserve dollar. Thus,thelegalreserveratiotogether
with the dollaramountof bank reservesarethefactorsthat
setthe upper limitto money creation.
What Are Bank Reserves?
Currencyheld in bank vaults may be countedas
legalreservesaswell as deposits (reservebalances) atthe
FederalReserveBanks. Both areequallyacceptablein
satisfactionof reserverequirements. Abank canalways
obtain reserve balancesby sendingcurrencyto itsReserve
Bank and canobtaincurrencyby drawingon itsreserve
balance. Because eithercanbe used to supporta much
largervolumeof depositliabilitiesof banks, currencyin
circulationand reservebalancestogetherare oftenrefer-
red to as"high-poweredmoney"orthe "monetarybase."
Reservebalancesandvault cash in banks, however,arenot
counted aspart of the money stockheld by thepublic.
4 Modem Money Mechanics
For individualbanks, reserveaccountsalso serveas
workingbalances? Banksmay increase the balancesin
their reserveaccountsby depositingchecksand proceeds
fromelectronicfundstransfersaswell ascurrency. Or
they may drawdown these balancesby writingcheckson
them orby authorizinga debitto them in paymentfor
currency,customers' checks,or otherfundstransfers.
Although reserveaccountsareused asworking
balances,eachbank must maintain,on the averageforthe
relevantreservemaintenanceperiod, reservebalancesat
the ReserveBank andvaultcashwhich together areequal
to itsrequired reserves,asdeterminedby the amountof
itsdepositsin the reservecomputationperiod.
Where Do Bank Reserves Come From?
Increasesor decreasesin bank reservescanresult
froma number of factorsdiscussed later in thisbooklet.
From the standpointof moneycreation,however,the
essentialpoint isthat the reserves of banksare,forthe
most part, Wities of the Federal ReserveBanks,and net
changesin them arelargelydeterminedby actionsof the
Federal ReserveSystem. Thus,the FederalReserve,
through itsabiityto varyboth the totalvolume of reserves
and the required ratio of reservesto depositliabilities,
influencesbanks' decisionswith respectto their assetsand
deposits. One of the major responsibilitiesof the Federal
ReserveSystemisto providethe total amountof reserves
consistentwith the monetaryneeds of the economyat
reasonablystableprices. Suchactionstake intoconsider-
ation,of course,anychangesin the pace atwhich money
isbeingused and changesin the public's demandsfor
cash balances.
The reader shouldbe mindfulthat depositsand
reserves tend to expand simultaneouslyand thatthe Fed-
eral Reserve's controloften is exertedthroughthe market-
place asindividualbanksfind it eithercheaperor more
expensiveto obtaintheir required reserves,dependingon
the willingnessof the Fed to supportthe currentrate of
creditand depositexpansion.
While an individualbank can obtain reservesby
biddingthem awayfromotherbanks, this cannotbe done
by the banking systemasawhole. Exceptfor reserves
borrowed temporarily from the Federal Reserve's discount
window, asis shownlater,the supplyof reservesin the
banking systemiscontrolledby the Federal Reserve.
Moreover,a givenincreasein bank reservesisnot
necessarilyaccompaniedby an expansionin money equal
to the theoreticalpotential based on the required ratio of
reservesto deposits. Whathappensto the quantityof

banks andthe public. A numberof slippagesmay occur.

much will be absorbedby depositsor otherliabiitiesnot

questionswillbe discussedlater in thisbooklet. The an-
swersindicatewhy changesinthe money supplymay be

In the succeedingpages,the effectsof varioustrans-
actionsonthe quantityof money aredescribed and illus-
trated. Thebasic workingtool isthe Taccount, which

Introduction 5
6. Bank Deposits-How l%ey Expand or Contract
Let us assumethat expansionin the money stockis
desiredby the FederalReserveto achieveitspolicy objec-
tives. Oneway the centralbank can initiate suchan expan-
sionisthrough purchasesof securitiesin the open market
Paymentforthe securitiesaddstobank reserves. Such
purchases (and sales) arecalled"open market operations."
How doopen market purchasesadd to bank reserves
and deposits? Supposethe Federal ReserveSystem,
through itstrading desk at the FederalReserveBank of
New York,buys$10,000of Treasurybillsfroma dealerin
U.S. governmentsecuritie~.~In today's world of computer-
ized financialtransactions,the FederalReserveBank
pays forthe securitieswith an "electronic"checkdrawn
on itself! Via its"Fedwire" transfer network, the Federal
Reserve notifiesthe dealer's designatedbank (BankA)
that payment for the securitiesshouldbe credited to (de-
posited in) the dealer'saccountat BankA At the same
time, BankA's reserveaccountatthe FederalReserve
iscreditedforthe amountof the securitiespurchase.
The FederalReserve Systemhas added $10,000of securi-
ties to itsassets,which ithas paid for,in effect, by creating
aliabilityonitself in the formof bank reservebalances.
These reserveson BankA's books arematchedby
$10,000of the dealer's depositsthat did not existbefore.
See illustration 1.
How the Multiple Expansion ProcessWorks
If the processendedhere,therewould be no "multi-
ple" expansion,i.e., depositsandbank reserveswould
havechangedby the sameamount However,banksare
requiredto maintainreservesequalto onlya fraction of
their deposits. Reservesin excessof this amountmaybe
used to increase earningassets-loansand investments.
Unused orexcessreservesearnno interest Undercurrent
regulations,the reserverequirementagainstmost transac-
tion accountsis 10percent5 Assuming,for simplicity,a
uniform 10percent reserverequirementagainstalltransac-
tion deposits,andfurther assumingthat allbanksattempt
to remain fullyinvested,we cannowtracethe processof
expansionin depositswhich can take place on the basisof
the additionalreservesprovided by the Federal Reserve
System's purchaseof U.S. governmentsecurities.
Theexpansionprocessmay ormay not begin with
BankA, dependingonwhat the dealerdoeswith the mon-
eyreceivedfromthe saleof securities. If the dealerimme-
diatelywriteschecksfor$10,000and allof them are
depositedin otherbanks, BankAlosesboth depositsand
reservesand showsno net changeasa result of the Sys-
tem's openmarketpurchase. However,otherbankshave
receivedthem. Mostlikely,a part of the initialdepositwill
remain with BankA, and a partwillbe shifted to other
banks asthe dealer'schecksclear.
6 Modem Money Mechanics
It doesnot reallymatterwherethismoney is atany
giventime. The importantfactisthat thesedeposits do not
disappear. Theyarein somedepositaccountsatalltimes.
All bankstogether have $10,000of depositsand reserves
thatthey did nothave before. However,they arenot
requiredto keep $10,000of reservesagainstthe $10,000
of deposits. All they need to retain,under a 10percent
resenrerequirement, is$1,000. The remaining$9,000is
"excessreserves." Thisamountcan be loaned or invested.
See illustration 2.
If businessisactive,the bankswith excessreserves
probablywillhave opportunitiesto loan the $9,000. Of
course,they donot reallypay outloansfromthe money
theyreceiveasdeposits. If they did this,no additional
moneywould be created. Whatthey dowhen they make
loansisto acceptpromissorynotesin exchangeforcredits
to the borrowers' transactionaccounts. Loans (assets)
anddeposits (liabilities) both riseby $9,000. Reservesare
unchanged by the loan transactions. Butthe depositcred-
itsconstitutenewadditionsto the totaldepositsof the
banking system. See illustration 3.

any resemblancetoactualtransactions. Forexample,openmarketopera-
tions typically are conductedwith many dealers and in amountstotaling

"low reserve tranche"-at $25 million, and provided for it to change

reserve tranchewas $41.1million in 1991and $42.2millionin 1992. The
Garn-St Germain Act of 1982 further modiied these requirements by

Thecustomerdepositat Bank A likely will be transfeerred,in part, to otherbanks and quickly loses its identity amid the huge

In thefirst stageof the process, totalloansand depositsof
the banksrise by an amountequalto the excessreserves
existingbefore anyloanswere made (90percent of the
initialdepositincrease). At the end of Stage 1,deposits
have risen a total of $19,000 (theinitial$10,000provided
by the FederalReserve's action plus the $9,000in deposits
createdby Stage1banks). See illustration 4. However,
only$900 (10percent of $9,OOO) of excessreserveshave
been absorbedby the additionaldepositgrowth at Stage 1
banks. See illustration 5.
Thelendingbanks,however, donot expectto retain
the depositstheycreatethrough theirloan operations.
Borrowerswrite checksthatprobablywillbe depositedin
otherbanks. As thesechecksmovethroughthe collection
process,the FederalReserveBanks debitthe reserve
accountsof thepayingbanks (Stage 1banks) and credit
those of the receivingbanks. See illustration 6.
Whether Stage1banks actually dolosethe deposits
to otherbanks orwhetheranyor allof theborrowers'
checksareredepositedin thesesame banksmakesno
differencein the expansionprocess. If thelendingbanks
expect to losethese deposits-and an equalamountof
reserves-asthe borrowers' checksarepaid,theywill not
lend more than theirexcessreserves. Likethe original

banking system. Whicheverbanksreceivethem also

Assuming thatthe banksholdingthe $9,000of d e
posits created in Stage1in turn makeloansequalto their
excessreserves,then loansand depositswill rise by a
further$8,100in the secondstage of expansion. This
processcan continueuntil depositshave risen to the point
whereallthe reservesprovided by the initialpurchaseof
governmentsecuritiesby the Federal ReserveSystemare
just sufficientto satisfyreserverequirementsagainstthe
newly created deposits. (Seepages 10and 1I.)
Theindividualbank, of course,isnot concerned as
to the stagesof expansionin which itmay be participating.
Mows and outflowsof depositsoccurcontinuously. Any
depositreceived isnew money,regardlessof itsultimate
source. Butif bank policyisto makeloansand invest-
ments equaltowhatever reservesarein excessof legal
requirements,the expansionprocesswill be carriedon.
How Much Can Deposits Expand
in the Banking System?
Thetotalamountof expansionthat cantakeplace
is illustrated onpage 11. Carriedthrough to theoretical
limits,the initial$10,000of reserves distributedwithinthe
banking systemgivesrise to an expansion of $90,000in
bank credit (loans and investments) and supportsa total of
$100,000in new depositsunder a 10percent reserver e
quirement. The depositexpansionfactorfor a given
8 Modern Monqr Mechanics
amountof new reservesisthus the reciprocal of the r e
quiredreservepercentage (1/.10 = 10). Loan expansion
willbe lessby the amountof the initialinjection. Themulti-
ple expansionispossible becausethe banksasa group
arelike onelargebank inwhich checks drawnagainst

depositors,with no net changein total reserves.

Depositexpansioncanproceed ii-ominvestments

probablypurchasesecurities. If the sellersof the securities
were customers,the bankswould makepaymentby credit-
ingthe customers'transaction accounts;depositliabiities
would risejust asif loanshad been made. Morelikely,
thesebankswould purchasethe securitiesthrough deal-
ers,paying forthem with checkson themselvesor ontheir

the sellers'banks. In eithercase,the net effectsonthe

manymore stages,in progressivelysmallerincrements,until the entire 10,000of reserveshave been absorbed
by depositgrowth. Asisapparentfromthe summarytableonpage 11,more than tw&hiidsof the deposit

12. How Open Market Sales Reduce Bank Reserves
and Deposits
Now supposesomereductionin the amountof
money isdesired. Nonnally thiswould reflecttemporary
or seasonalreductionsin activityto be hawed since,on
ayear-to-yearbasis, agrowing economyneeds atleast
somemonetary expansion. Just aspurchasesof govern-
ment securitiesby the pederal ReserveSystemcan pre
vide thebasisfor depositexpansionby addingto bank
reserves, salesof securitiesby the Federal ReserveSystem
reduce the money stockby absorbingbank reserves. The
processisessentiallythe reverseof the expansionsteps
just described.
Supposethe FederalReserveSystemsells$10,000of

the reserve accountsof banks areboth reduced $10,000.
The$10,000reductionin BankA's depositliabilitiesconsti-
tutes a declinein the money stock. Seeillustration 11.
Contraction Also Is a Cumulative Process
While BankA mayhave regainedpart of the initial
reduction in depositsfromotherbanksasa result of inter-
bank depositflows,allbankstaken togetherhave $10,000
lessin both depositsand reservesthan they had before
the FederalReserve's salesof securities. The amountof
reservesfreed by the declinein deposits,however,isonly
$1,000(10percent of $10,000). Unless thebanksthatlose
the reservesand depositshad excessreserves,they are
leftwith a reserve deficiencyof $9,000. See illustration 12.
Although they mayborrow fromthe Federal Reserve
Banksto coverthis deficiencytemporarily,soonerorlater
the bankswill have to obtainthe necessary reservesin
someotherway or reducetheir needsfor reserves.
Oneway for a bank to obtainthe reservesit needs
isby sellingsecurities. But, asthe buyersof the securities
pay forthemwith fundsin their depositaccountsin the
sameor otherbanks, the net result isa $9,000declinein
securitiesand depositsat allbanks. See illustration 13.
At the end of Stage 1of the contractionprocess, deposits
have been reduced by a totalof $19,000 (theinitial $10,000
resultingfrom the Federal Reserve's action plus the $9,000
in depositsextinguishedby securitiessalesof Stage 1
banks). See illustration 14.
However,thereisnowa reservedeficiencyof $8,100
atbankswhose depositorsdrewdown their accountsto
purchasethe securitiesfrom Stage 1banks. Asthe new
groupof reservedeficientbanks,in turn,makesup this
deficiencyby sellingsecuritiesor reducingloans,further
depositcontractiontakesplace.
Thus,contractionproceedsthrough reductionsin
depositsandloansor investmentsin one stageafteranoth-
er until total depositshave been reduced to the point
12 / Modem MoneyMnhanics
wherethe smallervolume of reserves isadequateto sup
port them. The contractionmultipleisthe sameasthat
which appliesin the caseof expansion. Under a 10percent
reserverequirement,a $10,000reductionin reserveswould
ultimatelyentailreductions of $100,000in depositsand
$90,000inloansandinvestments.
As in the caseof depositexpansion,contractionof
bank depositsmay take place as a result of eithersalesof
securitiesorreductions of loans. While someadjustments
of both kinds undoubtedlywould be made,the initialim-
pactprobablywould be reflectedin salesof government
securities. Mosttypes of outstandingloanscannotbe
calledforpayment prior to their due dates. Butthe bank
may ceaseto make newloansor refuse to renewoutstand-
ingonesto replacethosecurrentlymaturing. Thus,depos
itsbuilt up by borrowersfor the purposeof loan retirement
would be extinguished asloanswere repaid.
There is oneimportantdifferencebetween the expan-
sion and contractionprocesses. Whenthe FederalReserve
Systemaddsto bank reserves,expansionof creditand
depositsmay take place up to the limitspermittedby the
minimum reserveratio that banksarerequired to maintain.
Butwhen the Systemactsto reducethe amountof bank
reserves,contractionof creditand depositsmust takeplace
(exceptto the extentthat existingexcessreserve balances
and/or surplusvaultcash areutilized) to the pointwhere
the required ratio of reserves to depositsisrestored. But
the signi6canceof this difference shouldnot be overempha-
sized. Becauseexcessreservebalancesdonot earninter-

14. Bank Reserves-How l%eyChange
Moneyhas been detined asthe sum of transaction
accountsin depositoryinstitutions,and currencyandtrav-
elerschecksin the hands of the public. Currencyis some
thingalmosteveryoneuses everyday. Therefore,when
mostpeoplet h i i of money,theythink of currency. Con-
traryto this popular impression,however,tmtlsactiolr

Peoplekeep enoughcurrencyon hand to effect smallface

actionsthan do individuals.
Sincethe mostimportantcomponentof moneyis

ported by reserves,the centralbank's influenceovermon-
eyhingeson itscontroloverthe totalamountof reserves
and the conditionsunderwhich bankscan obtain them.
The preceding illustrationsof the expansionand
contractionprocesseshave demonstratedhow the central
bank, by purchasing and sellinggovernmentsecurities,
can deliberatelychangeaggregatebank reservesin order
to affectdeposits. But open market operationsare only
one of a number of kinds of transactionsor developments
that causechangesin reserves. Somechangesoriginate
from actionstakenby the public,by theTreasuryDepart-
ment, by the banks, orby foreign andinternationalinstitu-
tions. Otherchangesarisefromthe servicefunctionsand
operatingneedsof the Reserve Banksthemselves.
Thevariousfactorsthat provide and absorbbank
reserve balances,togetherwith symbolsindicatingthe
effectsof these developments,arelistedonthe opposite
page. Thistabulation alsoindicatesthe nature of the bal-
ancingentriesonthe Federal Reserve's books. Co the
extentthat the impactisabsorbedby changesinbanks'
vaultcash,the Federal Reserve's books are unaffected.)
Independent FadorsVersus PolicyAction
It isapparentthat bank reservesare affectedin sev-
eralways thatare independentof the controlof the central
bank. Most of these "independent?elementsare changing
more orlesscontinually. Sometimestheir effectsmay last
only a day or twobeforebeiig reversed automatically.
Thishappens,forinstance,when bad weatherslowsup the
checkcollectionprocess,givingrise to an automaticin-
creasein Federal Reserve creditin the form of "float."
Otherinfluences,suchaschangesin the public's currency
holdings,may persistforlongerperiodsof time.
Stillothervariationsin bank reservesresult solely
from the mechanicsof institutionalarrangementsamong
theTreasury,the FederalReserveBanks,and the deposi-
tory institutions. TheTreasury,for example,keepspart of
itsoperatingcash balanceon depositwith banks. But
virtually all disbursementsare made from itsbalancein
I4 I Modern Money Mechanics
the ReserveBanks. As is shownlater, anybuildupin bal-
ancesatthe ReserveBanksprior to expenditureby the
Treasurycausesa dollar-fordollardrainon bank reserves.
In contrastto these independentelementsthat affect
reservesare the policy actionstaken by the Federal Re
serveSystem. Theway Systemopen market purchases and
salesof securitiesaffectreserveshas alreadybeen d e
scribed. In addition,there are two otherwaysin which the
Systemcanaffectbank reservesand potentialdepositvol-
ume directly:first,through loansto depositoryinstitutions;
and second,through changesin reserve requirementper-
centages. A changein the required reserveratio,of course,
doesnot alterthe dollarvolume of reserves directlybut
doeschangethe amount of depositsthat a givenamount of
reservescan support.
Any changein reserves,regardlessof itsorigin,has
the samepotentialto affect deposits. Therefore,in orderto
achievethe net reserve effectsconsistentwith itsmonetary
policy objectives,the FederalReserveSystemcontinuously
must take accountof what the independentfactorsare
doingto reservesand then,using itspolicytools,offsetor
supplementthem asthe situationmay require.
By farthe largestnumber and amount of the Sys
tern's gross open markettransactionsare undertaken to
offset drainsfrom or additionsto bank reservesfrom non-
FederalReservesourcesthat mightotherwisecauseabrupt
changesin creditavailabiity. In addition,Federal Reserve
purchasesand/or salesof securitiesare madeto provide
the reservesneeded to supportthe rate of moneygrowth
consistentwith monetary policy objectives.

Changesin the amountof currencyheld by the

currencydemand,the exchangeisoneto one. A $1in-

Supposea bank customercashed a $100checkto
obtaincurrencyneeded for aweekend holiday. Bank
depositsdecline$100becausethe customerpaysfor the
currencywith a checkonhis orher transactiondeposit;
and thebank'scurrency (vaultcash reserves) isalso r e
duced $100. See illustration 15.
Now the bank has lesscurrency. It may replenish
itsvaultcashby orderingcurrencyfromitsFederalRe
serveBank -makingpaymentby authorizinga charge
to itsreserve account. Onthe ReserveBank's books,the
chargeagainstthe bank'sreserveaccountisoffsetby an
increasein theliabilityitem "FederalReservenotes." See
illustration 16. The ReserveBank shipmentto thebank
mightconsist,atleastin part, of US. coinsratherthan
FederalReserve notes. All coins,aswell asa smallamount
of paper currencystilloutstandingbut no longerissued,
are obligationsof theTreasury. Tothe extentthat ship
ments of cash to banksarein the formof coin,the offset-
ting entryon the ReserveBank's books isa declinein its
assetitem "coin."
Thepublic nowhas the samevolumeof money as
before,exceptthat more isin the formof currency and
lessis in the form of transactiondeposits. Under a 10
percent reserve requirement,the amountof reservesre-
quired againstthe $100of depositswas only$10,while a
full$100of reserveshave been drainedawayby the dis
bursement of $100in currency. Thus,if the bank had no
excessreserves,the $100withdrawalin currencycausesa
reserve deficiencyof $90. Unlessnewreservesarepro-
videdfrom someother source,bank assetsand deposits
will haveto be reduced (accordingto the contractionpro-
cessdescribedon pages 12and 13)by an additional$900.
At thatpoint, the reservedeficiencycaused by the cash
withdrawalwould be eliminated.

22. Changesin Service-RelatedBalances
andA&&ments
In orderto fostera safeand efficientpaymentssystem,
the Federal Reserve offersbanksavarietyof paymentsser-
vices, Priorto passage of the Monetary ControlAct in 1980,
the Federal Reserve offeredits servicesfree,but onlyto
banksthat were membersof the Federal ReserveSystem.
TheMonetaryControlAct directed the Federal Reserveto
offeritsservicesto alldepositoryinstitutions,to chargefor
these services,and to reduceandprice FederalReserve
float.13 Except forfloat,allservicescovered by theActwere
pricedby the end of 1982. Implementationof floatpricing
essentiallywascompleted in 1983.
Theadvent of FederalReservepriced servicesled
to severalchangesthat affectthe use of fundsin banks' re-
serveaccounts. As a result,onlypart of the totalbalancesin
bank reserve accountsisidentifiedas"reservebalances"
availableto meet reserverequirements. Otherbalancesheld
in reserveaccountsrepresent "service-relatedbalancesand
adjustments (tocompensateforfloat)." Service-relatedbal-
ancesare"requiredclearingbalances"held by banksthat use
FederalReserve serviceswhile"adjustments"representbal-
ancesheld by banksthatpay for floatwith as-of adjustments.
An Increase in Required Clearing B b c e s
Reduces Reserve Balances
Proceduresfor establishingand maintainingclearing
balances were approvedby the Board of Governorsof the
FederalReserve Systemin February 1981. Abank may be
requiredto hold a clearingbalanceif ithas no required re-
servebalance or if itsrequired reservebalance (held to satis-
fy reserverequirements) isnotlargeenoughto handle its
volumeof clearings. Tmicallya bank holdsboth reservebal-
ancesandrequired clearingbalancesin the samereserve

24. ChangesinLoans to
Depository Institutions
Loans to depository institutions
monthly averages, billions of dollars, not seasonally adjusted
Prior to passage of the Monetary ControlAct of 1980,
onlybanks that were members of the Federal Reserve Sys-
tem had regular accessto the Fed's "discountwindow."
Sincethen, all institutionshaving depositsreservableunder
theAct alsohave been ableto borrow fromthe Fed. Under
conditionssetby the Federal Reserve,loansare available
under three credit programs: adjustment, seasonal,and ex-
tended credit.16 The averageamountof each type of discount
windowcredit provided variesover time. (See rlrn~-fi
When a bank borrowsfroma FederalReserve Bank, it
borrows reserves. The acquisitionof reserves in this manner
diem in an importantway from the cases already illustrated.
Banksnormally borrow adjustmentcredit onlyto avoid re-
servedeficienciesor overdrafts,not to obtain excessre-
serves. Adjustmentcreditborrowings,therefore, are
reserves on which expansion has already taken place. How
can this happen?
In their effortsto accommodatecustomersas well as to
keepfullyinvested,banks frequentlymake loansin anticipa-
tion of inflowsof loanablefundsfromdepositsor money
market sources. Loans add to bank depositsbut not to bank
reserves. Unless excessreserves can be tapped, banks will
not have enough reserves to meet the reserve requirements
againstthe new deposits. Likewise,individualbanks may
incur deficienciesthrough unexpected depositoutflowsand
correspondinglosses of reserves through clearings. Other
banks receivethese depositsand can increase their loans
accordingly,but the banks that lost them may not be ableto
reduce outstandingloansor investmentsin order to restore
their reserves to required levelswithin the required time
period. In either case, a bank may borrow reserves tempo-
rarily fromitsReserve Bank.
Supposea customer of Bank Awantsto borrow $100.
On the basisof the management'sjudgment that the bank's
reserveswillbe sufticientto provide the necessary funds,the
customeris accommodated. The loan is madeby increasing
"loans"and creditingthe customer's depositaccount. Now
BankA's depositshave increased by $100. However, if re-
servesare insufticientto supportthe higher deposits,Bank A
will have a $10reserve deficiency,assumingrequirements of
10percent. See zllustratlo~z26. Bank Amay temporarily
borrowthe $10from its Federal Reserve Bank,which makes
a loanby increasingits asset item "loansto depositoryinstitu-
tions" and crediting Bank A's reserve account. Bank A
gains reserves and a correspondingliability"borrowingsfrom
FederalReserveBanks." See tlitutruiito~z27
To repay borrowing, a bank must gain reserves through
either depositgrowth or asset liquidation. 3cr ~llrrstrntio~z2%
Abank makes payment by authorizinga debitto its reserve
account atthe Federal Reserve Bank. Repaymentof borrow-
ing,therefore,reduces both reserves and "borrowingsfrom
FederalReserveBanks." S ~ Pziiustmtzon 29
Unlike loans made under the seasonaland extended
creditprograms,adjustmentcredit loans to banks generally
Extended credit
must be repaid within a shorttime sincesuch loans are made
primarilyto cover needs created by temporaryfluctuationsin
deposits and loansrelativeto usual patterns. Adjustments,
such as sales of securities,made by some banks to "get out
of the window" tend to transfer reserve shortages to other
banks and may forcethese other banks to borrow, especially
in periods of heavy credit demands. Even at timeswhen the
totalvolume of adjustmentcredit borrowing is rising, some
individualbanks are repayingloanswhile others are borrow-
ing. In the aggregate, adjustmentcredit borrowing usually
increases in periods of rising business activitywhen the
public's demands for credit are rising more rapidly than
nonborrowedreserves are being provided by Systemopen
market operations.
Although reserve expansionthrough borrowingis initi-
ated by banks, the amount of reserves that banks can acquire
in thisway ordinarilyislimitedby the Federal Reserve's ad-
ministration of the discountwindowand by its controlofthe
rate charged banks for adjustmentcredit loans-the discount
rate.17 Loansare made onlyfor approved purposes, and other
reasonablyavailable sources of funds must have been fully
used. Moreover,banks are discouragedfromborrowingad-
justment credit too frequentlyor for extended time periods.
Raisingthe discountrate tends to restrain borrowingby
increasingits cost relativeto the cost of alternativesources
of reserves.
Discountwindow administrationis an importantadjunct
to the other Federal Reservetoolsof monetarypolicy. While
the privilege of borrowing offersa "safetyvalve"to temporarily
relieve severe strains on the reserve positions of individual
banks, there is generallya strong incentivefor a bank to repay
borrowing beforeaddingfurther to its loansand investments.

Thusfarwe have describedtransactionsthat affectthe
volume of bank reservesand the impactthesetransactions
haveupon the capacityof the banksto expandtheirassets
and deposits. It isalsopossible toiduence depositexpan-
sionorcontractionby changingthe required minimumratio
of reservesto deposits.
Theauthoritytovary required reserve percentagesfor
banksthatwere membersof the FederalReserve System
(memberbanks) was firstgranted by Congresstothe Fed-
eralReserve Board of Governorsin 1933. The rangeswithin
which this authoritycanbe exercisedhavebeen changed
severaltimes,mostrecentlyin the MonetaryControlAct of
1980,which providedforthe establishmentof reserve r e
quirementsthatapplyuniformlyto alldepositoryinstitutions.
?he 1980statuteestablishedthe followinglimits:
On transadon accounts

above $25 million 8%to 14%
On nonpmonal time deposits 0%to 9%
The 1980lawinitiallysetthe requirementagainsttransaction
accountsover$25million at 12percent andthat against
nonpersonaltime depositsat3percent Theinitial$25mik
lion "lowreservetranche"wasindexed to changeeachyear
in linewith 80percent of thegrowth in transactionaccounts
atalldepositoryinstitutions. (For example,thelowreserve
tranchewas increased from$41.1millionfor 1991to $42.2
million for 1992.) In addition,reserve requirementscan be
imposedon certainnondepositsourcesof funds,suchas
Eurocurrencyliabiitie~?~(Initiallythe Board seta 3percent
requirementon Eurocurrencyliabiitiea)
The Garn-StGermainAct of 1982modiied these provi-
sionssomewhatby exemptingfromreserve requirements
thefirst$2million of totalresemble liabiitiesateachdepos
itoryinstitution. Similarto the lowreserve trancheadjust-
mentfortransaction accounts,the $2million "resemble
liabiitiesexemptionamount"was indexedto 80percent of
annualincreasesin totalresembleliabiities. (For example,
the exemption amountwas increased from $3.4 millionfor
1991to $3.6millionfor 1992.)
TheFederalReserve Board isauthorized to change,at
itsdiscretion,the percentagerequirementsontransaction
accountsabovethelow reserve trancheand on nonpersonal
time depositswithiithe rangesindicatedabove. In addition,
the Board may impose differingreserve requirementson
nonpersonaltime depositsbased on the maturityofthe de-
posit. m e Board initiallyimposedthe 3percent nonper-
sonaltime depositrequirement only on such depositswith
originalmaturitiesof underfouryears.)
Duringthe phasein period,which ended in 1984for
mostmember banksand in 1987for most nonmemberinsti-
tutions,requirementschanged accordingto a predetermined
schedule,withoutanyactionby the FederalReserveBoard.
Apart fromthese legallyprescribedchanges,oncethe Mone-
tary ControlAct provisionswere implementedin late 1980,
the Board did not changeanyreserve requirement ratiosuntil
late 1990. m e originalmaturitybreak for requirementson
nonpersonaltime depositswas shortened severaltimes, once
in 1982andtwice in 1983,in connectionwith actionstakento
deregulate ratespaid on deposits.) In December 1990,the
Board reduced reserve requirements againstnonpersonal
time depositsand Eurocurrencyliabilitiesfrom 3percentto
zero. EffectiveinApril 1992,the reserve requirementon
transactionaccountsabovethe low reservetranchewaslow-
eredfrom 12percentto 10percent.
When reserve requirementsarelowered,a portion of
banks' existingholdingsof required reservesbecomesexcess
reservesand may be loaned or invested. For example,with a
requirement of 10percent, $10of reserveswould be required
to support$100of deposits. See illustration30. Buta reduc-
tion in the legalrequirementto 8percentwould tieup only$8,
freeii$2outof each $10of reservesfor use in creatingaddi-
tionalbank creditand deposits. See illustration 31.
An increasein reserverequirements,on the otherhand,
absorbsadditionalreserve funds,andbankswhich haveno
excessreservesmust acquirereservesorreduce loansor
investmentsto avoid a reserve deficiency. Thusan increase
in the requirementfrom 10percentto 12percentwould boost
required reservesto $12foreach $100of deposits. Assuming
bankshave no excessreserves,thiswould forcethemto
liquidateassetsuntilthe reserve deficiencywas eliminated,
atwhich pointdepositswould be onesixthlessthan before.
See illustration 32.
Reserve Requirements and Monetary Policy
The powerto changereserve requirements,likepur-
chasesand salesof securitiesby the FederalReserve,isan
instrumentof monetarypolicy. Even a smallchangein r e
quirements-say,onehalf of onepercentagepoint-can
have a largeandwidespread impact. Otherinstrumentsof
monetarypolicy have sometimesbeen used to cushionthe
initialimpactof a reserverequirement change. Thus,the
Systemmay sellsecurities(or purchase lessthan otherwise
would be appropriate) to absorbpartof the reservesreleased
by a cutin requirements.
It shouldbe noted that in additionto their initialimpact
onexcessreserves,changesin requirements alterthe expan-
sionpower of everyreserve dollar. Thus,suchchangesaffect
the leverageof allsubsequentincreasesor decreasesin re-
servesfrom anysource. For this reason,changesin thetotal

Both reserve balancesandvaultcash areeligibleto

29. Foreign-RelatedTransactions for the Treasury
U.S. interventionin foreign exchangemarketsby the
FederalReserve usually is dividedbetween itsown account
and theTreasury'sExchangeStabilizationFund (ESF')ac-
count. The impacton U.S. bank reservesfromthe interven-
tion transactionisthe sameforboth -salesof dollarsadd
to reserveswhilepurchasesof dollarsdrainreserves. See
illustration 35 on pages 3@31. Dependingupon how the
Treasurypaysfor,orhances,itspart of the intervention,
however,the FederalReservemay not need to conduct
offsettingopenmarket operations.
TheTreasurytypicallykeeps onlyminimalbalances
in the ESFs accountatthe Federal Reserve. Therefore,
theTreasurygenerally has to convertsomeESFassetsinto
dollaror foreigncurrencydepositsin order to payfor itspart
of an intervention transaction. Likewise,the dollar or for-
eign currency depositsacquiredby the ESFin the interven-
tion typicallyare drawndownwhen the ESFinveststhe
proceeds in earningassets.
For example,to hance an interventionsaleof dollars
(such asthat shownin illustration 35),theTreasurymight
redeem someof the U.S. governmentsecuritiesissuedto
the ESF,resulting in a transferof fundsfromtheTreasury's
(generalaccount)balancesatthe Federal Reserveto the
ESFsaccountatthe Fed. (Onthe Federal Reserve's bal-
ancesheet, the ESFs accountisincluded in the liability
category"other deposits.") TheTreasury,however,would
need to replenish itsFed balancesto desiredlevels,perhaps
by increasingthe size of ?T&L calls-a transactionthat
drainsU.S. bank reserves. The interventionandfinancing
transactionsessentiallyoccur simultaneously. As a result,
U.S. bank reservesadded in the interventionsaleof dollars
areoffsetby the drainin U.S. bank reservesfromthe?T&L
call. See illustrations35 and 36 on pages 3@31. Thus,no
FederalReserveoffsettingactionswould be needed if the
Treasuryh c e d the interventionsaleof dollarsthrough
a?T&L callonbanks.
Offsettingactionsby the Federal Reservewould be
needed,however,if theTreasuryrestored depositsaffected
by foreign-relatedtransactionsthrough a number of transac-
tions involvingthe FederalReserve. These includethe
Treasury's issuanceof SDRorgold certificatesto the Feder-
al Reserve and the "warehousing"of foreign currenciesby
the FederalReserve.
SDR certtj5cate.s. OccasionallytheTreasuryacquires
dollardepositsfor the ESFs accountby issuingcertificates

If the ESFusesthese dollar depositsdirectlyin an
intervention saleof dollars,then the intervention-induced
increase in U.S. bank reservesisnot altered. See illustra-
tions 35 and 370n pages 3@31. If not needed immediately

Goldstock andgold certtj5cates. Changesin the U.S.
monetarygold stockused to be an importantfactor affecting
bank reserves. However,the gold stockandgoldcertificates
issued to the FederalReservein "monetizing"gold,have not
changedsignificantlysincethe early 1970s. (See chart on
thispage.)
Priorto August 1971,theTreasurybought and sold
goldfor a fixedpricein termsof U.S. dollars,mainly atthe
initiativeof foreigncentralbanks and governments. Gold
purchasesby theTreasurywere added to the U.S. monetary
gold stock,and paid forfromitsaccountatthe Federal
Reserve. Asthe sellersdepositedtheTreasury's checksin
banks, reservesincreased. To replenish itsbalance atthe
Fed,theTreasuryissued gold certificatesto the Federal
Reserveand received a creditto itsdepositbalance.
Treasurysalesof gold have the oppositeeffect Buy-
ers' checksarecredited to theTreasury'saccountand re-
servesdecline. Because the officialU.S. gold stockis now
fully"monetized,"theTreasurycurrentlyhas to use its
depositsto retiregold certificatesissued to the Federal
Reservewhenevergold issold. However,thevalueof gold
certificatesretired,aswell asthe net contractionin bank
reserves,isbased onthe officialgold price. Proceedsfrom
agold saleatthe marketpriceto meet demandsof domestic
buyerslikelywould be greater. The differencerepresents
theTreasury's profit,which,when spent,restores deposits
and bank reservesby a likeamount.
WhiletheTreasuryno longer purchasesgold and
salesof gold have been limited,increasesin the officialprice
of gold have added to thevalue of the gold stock. W e

Transactionsfor Foreign Customers
Manyforeigncentralbanksand governmentsmain-
tain depositsat the Federal Reserveto facilitatedollar-
denominatedtransactions. These"foreign deposits"on the
liabilityside of the Fed's balance sheettypicallyareheld at
minimallevelsthatvary littlefromweek to week. For ex-
ample,foreign depositsatthe FederalReserveaveraged
only$237million in 1991,rangingfrom$178million to $319
millionon aweekly averagebasis. Changesin foreign
depositsare smallbecause foreigncustomers"manage"
their FederalReservebalancesto desired levelsdailyby
buying and sellingU.S. governmentsecurities. The extent
of these foreigncustomer"cash management"transactions
isreflected,in part, by largeand frequentchangesin mar-
ketableU.S. governmentsecuritiesheld in custodyby the
Federal Reserveforforeigncustomers. (Seechart.) The
net effectof foreign customers'cash managementtransac-
tionsusuallyisto leaveU.S. bank reservesunchanged.
Managingfbreign depositsthroughsales ofsecurities.
Foreigncustomersof the FederalReservemake dollar-
denominatedpayments,includingthosefor intervention
salesof dollarsby foreign centralbanks,by drawingdown
their depositsatthe Federal Reserve. As these fundsare
deposited in U.S. banks and cleared,reserves of U.S. banks
rise. See illustration38. However,if paymentsfromtheir
accountsatthe FederalReservelowerbalancesto below
desiredlevels,foreigncustomerswill replenish their Feder-
al Reserve depositsby sellingU.S. governmentsecurities.
Actingastheir agent,the Federal Reserveusuallyexecutes
foreigncustomers' sellordersin the market. As buyerspay
for the securitiesby drawingdown depositsat U.S. banks,
reservesof U.S. banksfalland offset the increasein re-
servesfromthe disbursementtransactions. Thenet effect
isto leave U.S. bank reservesunchanged when U.S. govern-
ment securitiesof foreign customersare sold in the mar-
ket. See illustrations38 and 39. Occasionally,however,the
FederalReserve executesforeigncustomers' sellorders
withthe System's account. When thisis done,the risein
reservesfromthe foreign customers' disbursementof funds
remainsin place. See illustratiolzs 38 and 40. The Federal
Reservemightchooseto executesellorderswith the Sys-
tem's accountif an increase in reservesisdesiredfor do-
mesticpolicyreasons.

Managragrngfbreign deposits throughpurchases ofsecuri-
ties. Foreigncustomersof the FederalReservealsoreceive
a variety of dollardenominatedpayments, includingpro-
ceedsfrominterventionpurchasesof dollarsby foreign
centralbanks, that are drawn on U.S. banks. As thesefunds
arecreditedto foreign depositsatthe FederalReserve,r e
servesof U.S. banks decline. Butif receiptsof dollardenom-
hated paymentsraisetheir depositsatthe FederalReserve
to levelshigherthan desired,foreigncustomerswillbuy U.S.
governmentsecurities. The net effedtgenerally istoleave
U.S. bank reserves unchanged when the U.S. government
securitiesare purchased in the market.
Usingthe swap network. Occasionally,foreigncentral
banksacquiredollar depositsby activatingthe "swap"net-
work,which consistsof reciprocalshort-termcreditarrange-
mentsbetweenthe Federal Reserveand certainforeign
centralbanks. When a foreigncentralbank drawson its
swapline atthe Federal Reserve,itimmediatelyobtainsa
dollar depositatthe Fed in exchangeforforeigncurrencies,
and agreesto reversethe exchange sometimein thefuture.
Onthe FederalReserve's balance sheet,activationof the
swapnetworkisreflected asan increase in FederalReserve
Bank assetsdenominatedin foreigncurrenciesand an in-
creasein the liabiitycategoryYoreign deposits." Whenthe
swaplineisrepaid,both of these accountsdecline. Reserves
of U.S. bankswill risewhen the foreigncentralbank spends
itsdollarproceedsfromthe swapdrawing. See illustration
41. In contrast, reservesof U.S. bankswillfall asthe foreign
centralbank rebuilds its depositsatthe Federal Reserve
in orderto repaya swapdrawing.
The accountingentriesand impacton U.S. bank r e
servesarethe same if the FederalReserveuses the swap
networkto borrowand repayforeign currencies. However,
the Federal Reservehas not activatedthe swapnetwork in
recent years.
nTechnically, warehousing consists of two parts: the Federal Reserve's
agreementtopurchaseforeigncurrencyassetsfromtheTreaswyorESF
