ECB Raises Key Rates to 2.50% in September, a Second Hike in Three Months

The ECB lifted all three key rates by 25 basis points on 10 September 2026. The deposit rate reaches 2.50% on 16 September, repricing eurozone mortgage debt.

The Governing Council of the European Central Bank raised all three key interest rates by 25 basis points on 10 September 2026. From 16 September the deposit facility rate stands at 2.50%, the rate on main refinancing operations at 2.65% and the marginal lending facility at 2.90%. It is the second increase of the year: the deposit rate had already moved from 2.00% to 2.25% with effect from 17 June 2026, which leaves the price of central bank money in the euro area 50 basis points above its spring level.

The reason is energy, not housing

The decision statement is explicit about the driver. "The conflict in the Middle East continues to generate inflation pressures, and inflation is set to remain well above target for an extended period," the Council said, while repeating that it will keep a data-dependent, meeting-by-meeting approach rather than committing to a path.

The September staff projections put headline inflation at 3.0% in 2026, 2.5% in 2027 and 2.1% in 2028. Underlying inflation is seen at 2.5%, 2.6% and 2.3% across the same three years. That shape is worth a second look: in 2027 the core measure sits above the headline one, which is what happens when an energy-driven price shock fades faster than the domestic pressure it has already fed into wages and services. Growth is projected at 0.9% this year, 1.4% in 2027 and 1.5% in 2028.

How a policy step reaches a household

A deposit rate is not a mortgage rate, and the two do not move one for one. The transmission runs through money-market and swap pricing, which feeds the Euribor fixings that variable-rate loans in Spain, Portugal, Italy and Ireland are typically indexed to, and the swap curve that banks price new fixed-rate offers against. Because most Euribor-linked contracts reset every six or twelve months, a decision taken in September 2026 will reach a large share of household budgets only during 2027. Borrowers already on long fixed rates are unaffected until they refinance.

Where the cushion is thinnest on our own numbers

The Glopra snapshot dated 7 September 2026 shows how differently a 50 basis point year lands across the currency union. Gross rental yields run from 6.61% in Italy and 5.97% in the Netherlands down to 3.92% in Malta, 3.82% in Austria and 3.42% in Germany. The thinner the gross yield, the less room there is between what a property earns before costs and what financing it costs, and Germany and Austria sit at the narrow end of that range.

Price momentum is diverging just as sharply. Our stored annual price change is 17.8% for Portugal and 12.8% for Spain, against 4.2% for Austria, 1.4% for Germany and 0.1% for France. Portugal carries a Bubble Risk score of 84, the only reading in our European set inside the high band. A market running double-digit price growth on a gross yield of 4.29%, as Portugal is, has less absorptive capacity for a higher discount rate than one growing at 1.4% on a similar yield. None of this is a recommendation, and the gap between gross and net matters as much as the headline: round-trip transaction costs on our standardised case are 15.3% in Spain, 14.0% in Italy and 12.3% in Germany.
