No longer current — withdrawn, no replacement on file yet

Quick answerRBI has postponed the final 0.625% Capital Conservation Buffer tranche from April 1 to October 1, 2021, keeping minimum conservation ratios unchanged until then. The AT1 trigger stays at 5.5% of RWAs until October 1, 2021, when it rises to 6.125%.
What changed
The implementation of the last 0.625% tranche of the Capital Conservation Buffer (CCB) has been deferred from April 1, 2021 to October 1, 2021. The minimum capital conservation ratios specified in the Master Circular on Basel III Capital Regulations will continue to apply until the CCB reaches 2.5% on the new date. The pre-specified trigger for loss absorption through conversion or write-down of Additional Tier 1 instruments remains at 5.5% of risk-weighted assets until October 1, 2021, after which it will increase to 6.125%.
What it means for you
Banks get additional six months to build up the full 2.5% CCB, easing capital pressure amid COVID-19 stress. This deferral supports recovery by allowing banks to conserve capital for lending rather than meeting an earlier deadline. The AT1 trigger adjustment from October 1, 2021 will require banks to ensure adequate common equity to avoid conversion risks.
Historical instruction — do not use for current compliance. This is what was required at the time; it no longer reflects current RBI requirements. If no replacement rule is linked above, that only means none is recorded on our register yet — it does not prove no later applicable rule exists. Confirm on the official RBI source below.
What banks were required to do at the time
Update internal capital planning to reflect CCB reaching 2.5% by October 1, 2021 instead of April 1, 2021.
Maintain minimum capital conservation ratios as per existing framework until the new deadline.
Monitor AT1 instruments and ensure CET1 ratio stays above 5.5% of RWAs until September 30, 2021, and above 6.125% from October 1, 2021.
Communicate revised timelines to treasury and risk management teams for capital adequacy planning.
