Major Spanish banking institutions have reported minimal impact from the implementation of the new European capital regulation, CRR III. 

CaixaBank stated the regulation does not apply to them because 82.4% of its risk-weighted assets already utilize the standard method. Similarly, Santander and BBVA confirmed their exposure remains well below the required thresholds. Banco Sabadell is the only major bank to report a slight misalignment, with analysts projecting a marginal decrease in its CET1 ratio from 13.16% to 13.07% as the Basel III framework reform is phased in through 2030.
