Consider a bank with the following balance sheet (in million dollars):
Asset
Required Reserves $10, Excess Reserves $5, T bills $55, Commercial loans $60
Liability
Checkable deposits $100 Bank Capital $30
The bank makes a loan commitment for $6 million to a commercial customer. Calculate the banks capital ratio before and after the agreement. Calculate the banks risk weighted assets before and after the agreement. (please include explanation) thank you
