After the ECB decision (10 Sep 2026): how foreign buyers can lock a German mortgage for notarisation

What changed: the ECB decision and immediate effect

On 10 September 2026 the European Central Bank’s Governing Council raised its key rates. The press statement records that the deposit facility rate was increased to 2,50 %, the main refinancing rate to 2,65 % and the marginal lending facility to 2,90 %, all with legal effect from 16 September 2026. ([ecb.europa.eu](https://www.ecb.europa.eu/press/pr/date/2026/html/ecb.mp260910~314e508016.en.html?trk=public_post_comment-text&utm_source=openai))

This matters for German mortgage pricing because many bank funding costs and short‑term wholesale curves moved immediately after the announcement; lenders typically review retail mortgage prices and new offer levels in the days after a policy move. The precise repricing behaviour is a matter for each bank, so you must treat any quoted rate as time‑sensitive and confirm the lender’s written expiry or re‑pricing policy before proceeding.

Lender timing and the notary (how to avoid a surprise repricing)

Ask the lender explicitly for a binding written offer and its acceptance deadline before you fix the notary appointment. The single most important control for a buyer is the offer’s expressed validity: only a written commitment with an acceptance date gives you a defensible basis to demand the quoted rate.

When you book the notary (Beurkundung), tell the notary and the seller the acceptance deadline and request the notary to set the transfer / payment date (Fälligkeit des Kaufpreises) within that window. If the lender requires registration of a security (Grundschuld) and the land‑registry entry takes time, clarify whether the lender will honour the rate if registration is delayed for reasons outside your control. If a lender will not commit in writing, insist on a shorter notary date or on a fallback (see anti‑repricing clauses below). These are commercial negotiations; document every promise in writing and attach it to the loan offer.

FX hedging: steps to align currency cover with notarisation

If you are paying from a non‑EUR account, consider a forward FX contract to lock the EUR cost for the notary payment date. A forward contract commits you (and the bank) to exchange a set amount at a pre‑agreed rate on a future settlement date; it is commonly used to remove the risk of spot volatility between offer and payment.

Practical sequence: (1) agree the notary date and the expected EUR payment date, (2) open or confirm a foreign‑currency account with an FX provider that offers forwards, (3) instruct a forward (or, if you prefer optionality, an option structure) for that settlement date, and (4) ensure funds can be delivered from the forward settlement instruction to the German account named in the notary protocol. Check cut‑off times, settlement conventions and any margin / collateral calls with the FX provider in advance. Use a regulated bank or broker and get the provider’s written confirmation of settlement mechanics for the notary payment.

Sample anti‑repricing clauses (for negotiation)

Below are three short drafting options you can propose to a lender or attach as a rider to the loan offer. These are drafting examples for negotiation only — they are not legal advice.

1) Rate‑hold until notarisation: "Lender shall hold the offered fixed rate of [x.xx %] unchanged until the earlier of (a) the notarisation and signing of the purchase contract on [date], or (b) the stated offer expiry date. If notarisation is delayed due to seller or notary reasons, Lender shall extend the rate‑hold by up to [y] business days without additional charge."

2) Conditional reconfirmation: "If Lender receives evidence of an unavoidable delay to registration or disbursement outside Borrower’s control, Lender shall provide written reconfirmation of the offered rate or, alternatively, a revised offer that limits any rate increase to no more than [z] basis points above the original quote."

3) Fee‑compensation for repricing: "If Lender reprices the offer before notarisation, Lender shall compensate Borrower for documented additional interest costs incurred in the first [12] months after first payment, up to a maximum of EUR [amount]."

Use plain, dated attachments and require the lender’s authorised signatory to sign. If the bank refuses any written commitment, treat that as a material risk and either move the notary date or seek alternative lenders. Ask your German lawyer or solicitor to convert your chosen wording into German for insertion in the loan letter and into the notary file.

Final checklist and recommended professionals

Checklist: (1) Obtain a written loan offer with an explicit acceptance expiry; (2) fix a notary date within that expiry and record the expected EUR payment date in the notary protocol; (3) if paying from non‑EUR funds, arrange an FX forward tied to the payment date; (4) secure any written bank commitment on rate‑hold, registration timing and fallback remedies; (5) have a German lawyer review anti‑repricing wording before signature.

Do not rely on verbal assurances. If you are uncertain about drafting the clauses or the FX structure, consult a German property lawyer (Rechtsanwalt) and a regulated FX provider or your international bank. The ECB decision increased the policy anchor on 16 September 2026; treat current offers as time‑sensitive and document everything in writing.
