This spike is not an isolated statistical anomaly but a direct reflection of the European Central Bank’s (ECB) evolving monetary policy stance. With inflation in the eurozone standing at 2.5% in March—up six tenths of a percentage point from February—and Spanish consumer prices rising to 3.3%, markets are pricing in further interest rate increases to curb price growth. As Miquel Riera, a mortgage analyst at the comparator Helpmycash, noted, the March increase is the largest in magnitude since October 2022, underscoring the persistence of inflationary pressures that have kept the ECB on a hawkish path.
For households, the mechanics of the Euribor are translating into tangible financial strain. Borrowers with variable-rate mortgages subject to annual reviews will face higher installments for the first time since April 2024. This is because the current Euribor levels exceed those from a year ago, which stood at 2.398%. The impact is quantifiable: for the average mortgage in Spain, valued at 165,677 euros according to the National Statistics Institute (INE), the monthly payment for a variable-rate loan (Euribor plus one point) rises from 820.38 euros to 835.20 euros. This represents an additional 14.82 euros per month, or 177.84 euros annually. Those with semi-annual review cycles have already experienced increases since last October, facing an even steeper cumulative cost burden.
The ripple effects extend beyond existing borrowers to those entering the market. Fixed-rate mortgages, which have dominated new lending, are also becoming more expensive. In Spain, fixed-rate products account for more than two-thirds of all new mortgages, with CaixaBank reporting that 90% of its own portfolio is fixed-rate. However, the average interest rate for fixed mortgages in March climbed to 2.883%, up from 2.823% in February. Major lenders including Openbank, BBVA, Banco Santander, and ING have raised their fixed rates, reflecting a broader tightening of credit conditions. Mixed mortgages, which combine a fixed initial period with a variable rate later, also saw adjustments, with the fixed period rate ticking up slightly to 2.49% and the variable spread increasing to 0.75% + Euribor.
Analysts caution against expecting a sustained daily spike in the Euribor, noting that the current levels reflect market anticipation of future policy rather than a permanent structural shift in interbank lending. Forecasts for the coming years suggest a moderation in the rate environment, though from a higher baseline than previous cycles. CaixaBank Research estimates the daily one-year Euribor will average 2.23% this year, slightly below the 2.27% forecast for 2025 and above the 2.18% projected for 2027. Bankinter predicts a range of 2.3% to 2.45% for both this year and next, while Funcas, the foundation of former savings banks, forecasts an average of 2.24% for 2026 and 2027. These projections imply that while the most acute phase of the rate surge may be passing, borrowing costs will remain elevated for the foreseeable future.
The divergence between market expectations and central bank policy remains a critical variable. While the ECB’s decisions on the deposit facility rate directly influence the overnight €STR and, by extension, the Euribor, the interbank rate also incorporates a premium for term liquidity. Historically, ECB liquidity operations such as TLTROs have reduced this premium, but the current tightening cycle has unwound such effects. As long as inflation remains stubbornly above target, the market will continue to price in defensive hikes, keeping a lid on the potential for a sharp correction in mortgage rates. For consumers, this means the era of low-cost variable debt is firmly in the past, and the focus has shifted to managing higher fixed costs or navigating a more expensive variable adjustment.
