Perhaps the way to look at it is ‘Which isn’t the worst bank in Spain?’ ‘Best’ and ‘banks’ don’t belong in the same sentence.
1. Santander, BBVA and La Caixa are probably the safest. I have a very low opinion of all banks in Spain, especially the cajas. They all over-charge. I don’t know that any have a good reputation.
Weren’t all three downgraded last week 😕
