How National Australia Bank prices corporate credit

National Australia Bank is a Australia-based bank with approximately EUR 262bn of corporate credit exposure (EAD) under the Mixed approach to credit risk capital. The numbers below come directly from National Australia Bank's most recent Pillar 3 CR6 regulatory filings and are used to model how this bank prices corporate credit facilities.

What makes National Australia Bank's book distinctive

National Australia Bank is a smaller corporate book by disclosed EAD (34 of 59). Its cost-to-income ratio of 47.0% is structurally efficient (-2.8pp vs the 59-bank cross-section average of 49.8%). The corporate portfolio is mixed-grade, with an EAD-weighted average PD of 2.9% 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 43.0% is +6.2pp 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, National Australia Bank lands in the lower half of the pricing ranking (#44 of 59), with a RAROC of 6.98% and a minimum spread of 267bp to reach the 12% hurdle. Within Australia specifically, the bank ranks #2 of 4 on this same calculation.

To hit that hurdle on this exact deal, the bank would need a minimum spread of 267bp. This deal is significantly below target — the bank would either reprice it or decline.
