Banco de Portugal Governor Álvaro Santos Pereira Pushes Mortgage Taxa de Esforço Cap From 50% to 45% and Extends the Under-35 Maturity Ladder to 40 Years — Macroprudential Recommendations Head Toward Binding-Rule Status

Banco de Portugal Governor Álvaro Santos Pereira formally tabled the central bank's first macroprudential overhaul under his mandate on 27 May, walking the household-debt-service ceiling for new mortgage origination down from 50% to 45% of net disposable income, tightening the bank-level exception envelope from roughly 15% to 10%, and stretching the maximum loan tenor to 40 years for borrowers up to age 35 — three years above the current 37-year ceiling. The package was framed as aperto (tightening) on the affordability test and flexibilização (loosening) on the maturity ladder, calibrated to what the bank reads as the country's lengthening working-age horizon.

The Three Levers In Detail

• Taxa de esforço (debt-service-to-net-income ratio): the maximum cap drops from 50% to 45%. The metric is calculated on the new loan installment plus any other consumer-credit servicing, against the household's net disposable income after taxes and mandatory contributions. The five-point drop is the sharpest single move in the Banco de Portugal's macroprudential toolkit since the original 2018 recommendation introduced the 50% threshold.
• Exception envelope: banks were until now permitted to originate up to ~15% of new mortgage volume outside the standard limits — a release valve that absorbed first-time-buyer files at higher leverage. The envelope falls to 10%, compressing the bank-level discretion to break the standard cap.
• Maturity ladder for under-35s: the maximum tenor extends from 37 to 40 years, with the practical effect of dropping monthly installments at any given principal and bringing the installment under the new 45% ceiling for a wider household cohort. The recommendation also drops the previous requirement of holding the bank's quarterly-average weighted maturity at 30 years, simplifying compliance.

The Governor's Quote

Santos Pereira told the public hearing the bank is proposing a decrease in the taxa de esforço from 50% to 45%, a reduction of permitted exceptions to the taxa de esforço from around 15% to 10%, and tied the maturity extension to population longevity tendencies without — in his framing — an increase in risk. The Governor also delivered the package's political reveal: the Banco de Portugal wants the legislature to convert the macroprudential recommendations into binding rules, taking the framework out of the moral-suasion regime that has held since 2018 and into a statutory enforcement footing.

The Backdrop That Pulled the Trigger

The proposal lands on top of three data signals the bank cited inside the rationale. New-mortgage origination ran €1.78 billion in January 2026, off 18.6% month-on-month. The 3-month Euribor rebuild to 2.373% at this week's fixing — the highest since March 2025 — has reopened the floating-rate stress channel. And the Idealista Q1 2026 affordable-segment print shows fewer than 40,000 homes nationally priced under €300,000.

What This Means for Foreign Residents

• If you are mid-process on a mortgage application: the new caps are not yet in force; the change takes effect after the bank's board publishes the formal regulamento and banks adjust internal limits. The transitional window typically runs 30-60 days from the recommendation update.
• If you are under 35: the 40-year maturity option will be available, but only at banks that have updated their commercial offer — flag the new tenor explicitly when comparing simulation outputs.
• If you are above the 45% ratio under the current 50% cap: the exception envelope still exists at 10% of new volume, but banks will prioritise their best-credit-grade applicants inside the quota.
• If you watch the political track: conversion of the recommendation into binding law is a parliamentary call — watch São Bento for the diploma in the autumn session.

The Banco de Portugal's formal regulamento update is expected before the September-quarter close.
