Portugal's Average Mortgage Rate Nudges Up for the First Time Since January 2024 — New Borrowers Now Paying €700 a Month
INE data: Portuguese housing credit rate rose from 3.079% to 3.088% in March — the first uptick in 14 months. Euribor's Middle-East turn is the cause, and it hits new contracts hardest, where the average payment is now €700 (up 15.9% year-on-year).
The long fall in Portuguese mortgage costs has, for now, stopped. The National Statistics Institute (INE) published its March 2026 Housing Credit series on 21 April, and for the first time since January 2024 the average interest rate on Portugal's active stock of mortgages ticked up, from 3.079 per cent in February to 3.088 per cent. The move is technically tiny — nine-tenths of a basis point — but it ends a fourteen-month downward run that had become an assumed backdrop to the country's household finances.
Measured against the peak, the portfolio rate is still a full 1.569 percentage points below its January 2024 reading of 4.657 per cent. That cushion matters: the average monthly payment on the existing Portuguese mortgage stock is just €402, split 48.8 per cent to interest (€196) and 51.2 per cent to capital (€206). What has quietly changed beneath that number is the composition of the book. The average outstanding debt per contract has risen from €64,790 in January 2024 to €77,078 today — a reminder that Portuguese households have been borrowing larger amounts even as rates fell.
New contracts tell a harsher story
The headline portfolio numbers mask what is happening at the front door. Mortgages written in the last three months carry an average debt of €175,838 and a monthly payment of €700 — up 15.9 per cent year-on-year. That is the figure buyers should watch. It reflects the combination of still-elevated Lisbon, Porto and Algarve prices, larger loan principals, and a Euribor curve that has begun turning against borrowers again.
Portugal's mortgage market is overwhelmingly indexed to 6- and 12-month Euribor. Those benchmarks troughed in the first half of 2025 but started drifting higher from June 2025, when the US–Israel military campaign against Iran's nuclear facilities reshaped euro-area inflation expectations and pushed the ECB to pause further cuts. Mortgages reset on annual or semi-annual cycles, so the March 2026 uptick is the first wave of that shift flowing into the contractual book.
What this means for the housing outlook
Three concrete implications. First, affordability calculations used by banks in mid-2025 are now stale — applicants whose stress-test assumed 3 per cent flat are looking at a rate that could drift toward 3.3–3.5 per cent by year-end if the Middle East risk premium holds. Second, the pipeline of refinancings that banks marketed aggressively through 2025 loses a little of its edge: the average saving from moving bank has narrowed. Third, the March rent data INE released alongside the mortgage series — a 5.1 per cent year-on-year rise, with Madeira at 6.5 per cent — means the rent-versus-buy crossover point is shifting again, and not in renters' favour.
The policy backdrop
The government's housing package, adopted in February 2026, already assumed a stabilising rate environment to underpin its IMI reductions and young-buyer guarantees. An upward rate drift does not break that assumption, but it does stress-test it. The Bank of Portugal's April Financial Stability Report, due the week of 28 April, will be the first official reading on whether supervisors see the March tick as noise or as the opening move of a sustained reversal.
What to watch
The 12-month Euribor fix on 30 April — the single biggest input into Portuguese mortgage resets over May — will determine whether April's rate print retreats back below 3.08 per cent or pushes higher. A sustained break above 3.10 per cent would trigger refinancing-calculator updates at the big five Portuguese banks and almost certainly a fresh round of fixed-rate promotional offers. Households on variable-rate contracts due to reset in June and July should know their next instalment number within six weeks.
