What does day one cost?

The move from IRAC provisioning to ECL strikes an adjustment on 1 April 2027 against opening retained earnings — never through profit or loss — and the RBI allows a declining fraction of it back into CET1 over four years. This works out both.

The published worked example

These are not your figures. The analysis this schedule was transcribed from works through a ₹700 crore adjustment and arrives at about ₹370 crore of first-year relief — four fifths of it, net of 34% tax. Change any field and this notice goes. Amounts are in ₹ crore.

The day-one adjustment

To opening retained earnings₹700 cr

CET1 ratio, before any relief13.03% (-30.8 bp)

The adjustment is taken to opening retained earnings on the transition date. It does not pass through profit or loss, so no part of it is a result for any period.
The add-back reaches CET1, and so tier 1, total capital, the leverage ratio and large-exposure limits. It does not reach tier 2, it does not reduce exposure amounts under the standardised approach, and it does not reduce the leverage ratio exposure measure.
