Average historical spread mortgage − policy rate: 1.30pp. Current spread: 1.65pp. Above the long-run average — banks are charging a wider risk premium than usual.
Policy rate vs. typical fixed mortgage rate; the shaded area is the spread.
Where the typical fixed mortgage rate ends up if the futures-implied policy path holds and the historical spread reverts to its long-run mean.
The four tiles at the top show the live policy rate (set by European Central Bank), the interbank rate (€STR), and the typical fixed and variable mortgage rates available to a household in Eurozone. The gap between the policy rate and the mortgage rate is the spread — what the lender adds on top to cover funding, credit risk and profit.
The first chart shows that spread over the last five years. When the shaded area widens, banks are charging more on top of the policy rate, usually because the long bond market has moved or because banks are pricing in extra risk. When it narrows, competition or central bank bond-buying is squeezing margins. The second chart — the implied 12-month forward path — takes the current futures market's bet on where the policy rate is heading, applies the historical spread, and shows where your mortgage rate would land if both relationships hold. It is not a forecast: it is what current market pricing already implies.
The mortgage-minus-policy spread observed for Eurozone (1.65pp current vs 1.30pp historical mean) decomposes into four primary drivers. First, the funding curve: jurisdictions whose lenders fund predominantly via covered bonds (Germany, Denmark, France, Sweden) inherit the swap-plus-covered-spread basis, which moved from 5-15 bp pre-2022 to 25-50 bp during the ECB's APP/PEPP unwind. Lenders funded via deposit franchise (UK, Australia) anchor more to short-rate transmission and deposit beta. US lenders sell loans into agency MBS pools, so the spread is sensitive to the primary-secondary MBS basis and to Fed SOMA reinvestment policy.
Second, prepayment optionality and convexity: products without economic prepayment penalty (US 30Y, Danish callable bonds) trade at OAS rather than nominal spread; OAS widening during rate volatility regimes (VIX-Treasury MOVE comovement) bleeds straight into the borrower rate. Penalty-protected European products (German Festzins under §489 BGB, French indemnité de remboursement anticipé) carry minimal optionality premium. Third, lender duration mismatch: if the dominant local product is short-fixed (UK 2/5Y) the lender's asset-liability gap is small and the spread is stable; if long-fixed (US 30Y, German 10Y) lenders rely on swap and MBS markets to hedge duration, and spread widens when those hedge markets stress. Fourth, regulatory caps and capital treatment: France's taux d'usure, prudential LTV/DTI floors (Switzerland, Australia, Canada), and Basel III risk-weight differentiation across LTV buckets all alter the marginal cost of lending and feed back into quoted rates with lags of one to three quarters.

The European Central Bank sets three policy rates; the deposit facility rate has been the operationally binding rate since the introduction of excess reserves in 2008. The deposit rate anchors €STR (Euro Short-Term Rate), which sits within a few basis points of the deposit facility and serves as the reference for nearly all interbank funding.
The transmission to mortgage rates is faster and more complete than in the United States. Three structural reasons:
The Eurozone is not one market. The “typical” mortgage differs sharply across member states:
The 10-year German Festzinsbindung is the most-quoted Eurozone benchmark and the one we use for the snapshot table.
The Eurozone shows the cleanest transmission of any major economy. The spread between 10-year fixed mortgages and the ECB deposit rate has averaged roughly 1.3 percentage points since 2015, with two notable departures:
By mid-2026 the spread has normalised. The chart above shows the full path.
The forward path uses 3-month Euribor futures and €STR-OIS curves to imply the ECB deposit rate over the next year, then projects the typical 10-year Festzinsbindung by adding the historical spread. Because Eurozone pass-through is high (~85% within 4 months), the projected mortgage rate tracks the implied policy rate fairly closely.
