How much notice must a bank give before raising my mortgage rate?
A short answer, with the article it comes from.
The answer
At least 30 days before increasing the margin added to the base rate, and only where your contract permits a change. A move in the base rate itself, such as EIBOR, is the contract working as written. A bank may not vary your loan terms unless you agree in writing, and fee changes need two months' notice.
CBUAE Consumer Protection Standards Clause 2.1.3.21, and CBUAE Circular 31/2013 Article 4, checked 2 October 2026.
Clause 2.1.3.21 of the Consumer Protection Standards covers an increase "to the part of the Consumer's interest/profit rate that is added to the variable Base Lending Rate": the bank must not increase it "until after the 30 calendar days' notice period". The notice must give the date, the old and new rates, the effect on principal and interest, any new payment, and who to contact.
Article 4 of the mortgage circular covers terms in general: lenders "are not allowed to alter or vary terms and conditions of the loan or the facility during the tenor of the loan or the facility, unless agreed to in writing by the borrower", and for commissions or fees "customers must be notified, at least, two months prior to implementation of such changes".
A change in the benchmark is different. If your rate is a benchmark plus a margin, the benchmark moving changes your payment without any change to your terms, and the bank must still notify you of the new rate.
If you have been told your margin is rising, or your fixed period is ending, it is worth comparing the market before the notice runs out. A specialist can do that against your own loan.
Rules are the easy part. Your file is the question.
