Banks must maintain: CET1 Capital Adequacy Ratio (CAR) ≥6.5%, Tier 1 CAR ≥8%, Total CAR ≥10%, and minimum Total CAR of 12.5% when the Capital Conservation Buffer (CCB) of 2.5% is fully phased in. D-SIBs (Domestic Systemically Important Banks - DBS, OCBC, UOB) face an additional D-SIB buffer of 2%. Singapore adopts Basel III output floor (72.5% of standardised approach RWA) from January 2025 per Basel III finalisation.",
