Bankia has been authorized by the ECB to change the parameters used for its calculation of credit risk linked to its retail mortgage business, according to a statement it published on market regulator CNMV’s website on Tuesday. This will allow Bankia to lift its CET1 capital ratio to 160 bp from 13.27% to 14.87%, the highest among Spanish banks as well as could favor the bank in the merger process with CaixaBank.
