1- What is the common equity Tier I (CET1) risk-based capital
ratio?
2- What is the Tier I risk-based capital ratio?
3- What is the total risk–based capital ratio?
1.
Common equity tier 1 is a component of tier 1 capital and consists of common stock. Here as per the balance sheet the equity capital of the bank is $16 million and there is a reserve for loan losses amounting to $4 million the total of the two would give the CET1.
CET 1 ratio is calculated by divding CET 1 by risk weighted assets as follows:
CET 1 ratio = CET1/ RWA = (16+4)/(65+115) = 11.11%
2.
Tier 1 capital is the total of bank's tier 1 capital which includes all the banks common equity and other innovative securities which can form part of the bank's equity based on a trigger event. In the above case, The banks tier 1 capital is the total of common stock, reserve for loan loss and $2 million for FX forward contracts being in the money.
Tier 1 risk based ratio is calculated by dividing bank's tier 1 capital by risk weighted assets as follows;
Tier 1 risk based ratio = tier1 capital/ RWA = (16+4+2)/(65+115) =12.22%
3.
Total risk based capital ratio of a bank is calculated by adding tier 1 and tier 2 capitals and then dividing by risk weighted assets as follows:
Total risk based capital ratio = (16+4+2+8)/180 = 16.67%
