Sample RAROC calculation

On a representative BBB+ rated, 5-year term loan of EUR 25M at 150bp spread with a 20bp commitment fee, Westpac would generate an estimated RAROC of 6.88% against a typical 12% bank hurdle rate. To hit that hurdle on this exact deal, the bank would need a minimum spread of 271bp. This deal is significantly below target — the bank would either reprice it or decline.
