逆循環資本緩衝之目的,在銀行體系信用過度擴充
可能升高系統風險時,要求銀行增加計提資本,並
在信用循環反轉時釋出資本,以吸收銀行損失,降
低資本不足導致緊縮信用之風險。
Basel III規定逆循環資本緩衝比率介於0-2.5%之間
,須以普通股權益支應。此外,BCBS於2010年12
月發布「各國金融監理機關採行逆循環資本緩衝之
指引」(Guidance for National Authorities Operating
the Countercyclical Capital Buffer),要求各國金融監
理機關以信用/國內生產毛額(credit / GDP)比率為基
礎,且採行適當之判斷準則,監控及評估國內信用
成長情形,以決定逆循環資本緩衝水準。
