MADRID Dec 21 The European Court of Justice's
ruling overturning a Spanish court sentence that had capped
banks' liabilities for mortgage floor contracts could force
Spanish banks to repay customers slightly more than 4 billion
euros ($4.16 billion), a Bank of Spain source said on Wednesday.
Banks will now have to compensate customers for what they
lost on the mortgages, which could not fall below a benchmark,
before May 2013, when Spain's Supreme Court declared them
invalid if they had not been presented clearly.
The ruling, which banks and analysts were not expecting, is
final and cannot be appealed.
