How Mizuho Financial Group prices corporate credit

Mizuho Financial Group is a Japan-based bank with approximately EUR 82.5tn of corporate credit exposure (EAD) under the Mixed approach to credit risk capital. The numbers below come directly from Mizuho Financial Group's most recent Pillar 3 CR6 regulatory filings and are used to model how this bank prices corporate credit facilities.

What makes Mizuho Financial Group's book distinctive

Mizuho Financial Group is one of the five largest corporate credit books in the dataset (5th by EAD). Its cost-to-income ratio of 64.2% is in line with the European large-bank average (+14.4pp vs the 59-bank cross-section average of 49.8%). The corporate portfolio is mixed-grade, with an EAD-weighted average PD of 1.7% against a cross-bank average of 2.1%.

The consolidated book blends A-IRB and F-IRB sub-portfolios, so the headline PD and LGD averages mask meaningful dispersion between segments — relevant when benchmarking specific sectors or geographies. Unsecured LGD disclosed at 39.0% is +2.2pp against the 36.8% cross-bank average, indicating a harder workout profile than the peer median and pushing up capital consumption on defaulted exposures.

On the standardised BBB+ EUR 25M 5-year term loan used across every bank profile, Mizuho Financial Group lands in the top half of the pricing ranking (#28 of 59), with a RAROC of 7.37% and a minimum spread of 254bp to reach the 12% hurdle. Within Japan specifically, the bank ranks #2 of 3 on this same calculation.

To hit that hurdle on this exact deal, the bank would need a minimum spread of 254bp. This deal is significantly below target — the bank would either reprice it or decline.
