Basel I Capital Adequacy Norms Master Circular 2008

No longer current — withdrawn, no replacement on file yet
Source: Reserve Bank of India · RBI/2008-2009/31 · issued 01 Jul 2008 · ~2 min read
Quick answerRBI consolidated Basel I capital adequacy norms for banks not yet on Basel II. This circular sets risk weights, capital charges for credit and market risks, and minimum CRAR. Banks migrating to Basel II by March 2009 must still follow this until migration.

What changed

This master circular updates the previous July 2007 version by incorporating all instructions issued up to June 30, 2008. It consolidates guidelines on capital components, risk weights, and capital charges for credit and market risks under the Basel I framework. For banks that have already migrated to Basel II norms from March 31, 2008, the separate Basel II master circular applies.

What it means for you

Banks still on Basel I must continue to maintain capital as per these norms until they migrate. The circular provides explicit capital charges for credit risk, market risk (including interest rate, equity, and forex risks), and defines trading book components. It ensures a standardized approach for capital adequacy computation across commercial banks excluding RRBs.

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.

Who it affects
