Basel I Capital Adequacy Master Circular 2010

No longer current — withdrawn, no replacement on file yet
Source: Reserve Bank of India · RBI/2010-11/49 · issued 01 Jul 2010 · ~2 min read
Quick answerRBI consolidated Basel I capital adequacy norms for commercial banks (excluding RRBs) as of July 1, 2010. This circular updates previous instructions and applies only for calculating the prudential floor on capital, since banks have migrated to Basel II from March 31, 2009.

What changed

This master circular updates the July 2009 version by incorporating all instructions issued up to June 30, 2010. It consolidates guidelines on capital components, credit risk, market risk, and capital charge computation. The circular clarifies that these Basel I norms are now only relevant for computing the prudential floor on capital under the Basel II framework.

What it means for you

For Indian banks, this circular serves as a reference for the minimum capital floor requirement under Basel II. Banks must continue to compute their capital adequacy ratio using Basel I rules as a floor, until further notice. This ensures a safety net during the transition to more risk-sensitive Basel II norms.

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 is the key change from the previous master circular?
