Norinchukin hit with 54% rise in op RWAs

Recalibration of underlying parameters is first under new standardised measurement approach

The Norinchukin Bank’s operational risk charges jumped 54.1% in the three months to March 31, as Basel III’s new standardised computation parameters underwent their first annual reset.

Operational risk-weighted assets (RWAs) at Japan’s fifth-largest lender increased to ¥1.61 trillion ($10.3 billion) from ¥1.05 trillion at end-December – nearly doubling compared with the end-2022 figure, just before the bank adopted the revised formulas under the final Basel III rules.
