No specification on the time frame. Just says from the end of the fixed term the loan will not be more than 1.1% above the ECB rate.
Confusingly, directly after saying that, it says... "THE PAYMENT RATES ON THIS HOUSING LOAN MAY BE ADJUSTED BY THE LENDER FROM TIME TO TIME(does not apply if a further fixed rate period has been chosen)"
The only way it appears they can change the rate without contradicting themselves is to lower it, which seems unlikely, to say the least.
I hate banks.
