Euribor 3-Month Climbs to 2.373% on 9 June — Highest Reading Since March 2025 as Markets Brace for an ECB Hike Thursday
Tuesday's fixing lifts Portugal's three-month Euribor 2.2 basis points to 2.373% — the highest since March 2025 — with the 6-month at 2.606% and 12-month at 2.866%, all advancing on the same session that brings the European Central Bank's June policy meeting into view.
The three-month Euribor — the wholesale interest rate that anchors a quarter of Portugal's variable-rate mortgage stock — fixed at 2.373% on Tuesday 9 June, up 2.2 basis points on Monday's reading and the highest since March 2025. The six-month tenor advanced 2.0 basis points to 2.606%, the most-used rate for Portuguese variable-rate crédito habitação, and the 12-month climbed 5.0 basis points to 2.866%, the steepest single-day move across the curve.
The simultaneous rise across all three tenors reflects market positioning ahead of the European Central Bank's monetary-policy meeting, which concludes Thursday 11 June. The April Conselho de Governadores held rates for the seventh consecutive session after the eight cuts that began in June 2024, and futures pricing now puts a first 25-basis-point hike on the table — what would be Frankfurt's first tightening move in nearly three years.
For the Portuguese mortgage book, the breakdown matters more than the headline. April Banco de Portugal data place the 6-month Euribor at the centre of variable-rate stock at 39.56% of outstanding balances, with the 12-month at 31.53% and the 3-month at 24.55%. That mix means roughly four in ten Portuguese households on variable rates will re-anchor against today's 2.606% fixing on their next semi-annual reset — a level that has crept up steadily since May, when the 6-month monthly average sat at 2.536%.
The May monthly tape, published earlier this month, captures the same upward drift. The three-month average for May was 2.226% (+5.1 basis points on April), the six-month 2.536% (+8.2 basis points) and the 12-month 2.804% (+5.7 basis points). At Tuesday's daily fixings, all three tenors are now sitting at or above their May monthly highs, suggesting June will print another upward step when the monthly averages are tallied at the start of July.
For new borrowers signing a crédito habitação contract this month, the practical impact is two-fold. Indexant pricing tracks Euribor plus a contractual spread of typically 75 to 150 basis points, so a 6-month-indexed mortgage signed at Tuesday's reading prices around 3.36–4.11%. Stress-test rules from the Banco de Portugal additionally require lenders to model affordability at a higher rate — the central bank's stress add-on currently sits at 3 percentage points on contracts indexed to floating Euribor — which means today's 2.606% pushes the stress qualifier to 5.6%. Households at the income-affordability margin will find their borrowing envelope shrinking proportionally.
The Euribor curve's renewed climb arrives the same week the Banco de Portugal flagged wage compression in its June Boletim Económico, with the national minimum wage now sitting at 91% of the median. If Thursday's ECB call confirms a hike, the next 6-month Euribor reset window in early autumn will hit the 39.56% slice of the mortgage stock that has spent most of the past year absorbing successive cuts — turning the dial on monthly household debt service for the first time since the cutting cycle began.
