An investigation is underway by the CNMC into several banks in the country. The banks being investigated are Bankinter, Banco Santander, BBVA, Unicaja, CaixaBank, and Sabadell. The focus of the investigation is on practices related to the mortgage market.

The CNMC suspects that executives at these banks may have engaged in behavior that undermines competition. This potentially gave them an unfair advantage in the market. The alleged behavior involves communicating interest rate policies and guiding customers in certain ways.

Further details about the investigation can be found through El Mundo. The CNMC's inquiry is aimed at determining whether these banks have indeed engaged in anti-competitive practices in the mortgage sector.
