The European Central Bank will have a decision on interest rates next week, but still lacks data on March inflation. Mortgage repayments may already feel the consequences of the attack on Iran in April, but the effects will only be significant if the instability continues.
Attack on Iran puts pressure on Euribor rates and threatens home loan repayments

Context & Explainers
Euribor (Euro Interbank Offered Rate) is the benchmark interest rate at which major European banks lend to each other. It directly affects most variable-rate mortgages in Portugal, where the vast majority of home loans are indexed to 3-month, 6-month, or 12-month Euribor rates.
When Euribor rises, monthly mortgage payments increase at the next review date; when it falls, payments decrease. The European Central Bank's (ECB) monetary policy decisions are the primary driver of Euribor movements — rate hikes push Euribor up, while cuts bring it down.
Euribor peaked above 4% in late 2023 after aggressive ECB tightening, then gradually declined through 2024–2025 as the ECB began cutting rates. Portuguese homeowners with variable-rate mortgages should track Euribor trends and their mortgage review dates to anticipate payment changes.
