The conversion right §503 BGB explained
“The Mortgage Credit Directive makes this impossible” — that sentence appears in almost every rejection letter with a cross-border element. In many cases it is simply wrong. What matters is your residence, not the currency of your salary.
Does the conversion right affect you at all?
§503 BGB refers to the currency of the EU member state in which the borrower is resident at the time the contract is concluded — the statute calls it the borrower’s “national currency”. Anyone living outside the EU (Switzerland, UK, USA, UAE, Singapore) has no such national currency in the meaning of the provision. The conversion right does not apply there — regardless of whether the salary is paid in francs, dollars or pounds.
The reverse also holds: anyone living in an EU country without the euro — Denmark, Sweden, Poland, the Czech Republic — is fully covered. Even where the salary is paid in euros. For that group, a euro loan can legally be a foreign-currency loan. Counter-intuitive, but exactly what the wording says.
That is why a blanket rejection “because of the conversion right” is the wrong reason for a borrower resident in Zurich, London or Dubai. Banks still decline — but on other grounds.
What §503 BGB actually provides
The provision entered the German Civil Code on 21 March 2016 with the transposition of the EU Mortgage Credit Directive. It grants the consumer a right to demand that the mortgage be converted into their national currency.
- Trigger: the outstanding balance or the instalments — converted into the national currency — exceed the value at contract conclusion by more than 20 % because of exchange-rate movements.
- Effect: conversion at the market exchange rate on the day of the request, unless the contract provides otherwise.
- Not waivable: agreements to the consumer’s detriment are void. The bank cannot negotiate the right away.
- One lever does exist: under §503(1) sentence 3, the contract may define the national currency as being — exclusively or additionally — the currency in which the borrower predominantly earns income or holds assets used for repayment. Income currency enters the picture through that sentence only, by agreement, not automatically.
For the bank this is an option written against it: it is exercised only when the rate has moved against the customer. On top of that come monitoring and information duties (§493(4) BGB) for the entire term.
Three groups — and the middle one is the hardest
| Residence | Examples | Conversion right? | In practice |
|---|---|---|---|
| EU with the euro | Spain, Portugal, Austria, Netherlands, Italy, Cyprus | No | National currency = loan currency, so no foreign-currency loan. The easiest cross-border case; identification and proof of income remain. |
| EU without the euro | Denmark, Sweden, Poland, Czech Republic, Hungary, Romania | Yes, fully | Even with a euro salary. The hardest group — here EU membership is the disadvantage. Only banks with a working FX process remain. |
| Third country | Switzerland, UK, USA, UAE, Singapore, Hong Kong | No | No conversion right — yet many lenders still decline, for other reasons. Switzerland is the best-established case, the USA the hardest. |
The clearest proof that the statute, not the economic risk, decides this: the United Kingdom. While the UK was an EU member, the conversion right applied and financings failed over it. Brexit removed it — same country, same pound, same borrowers, suddenly financeable.
Why banks still say no
If the conversion right does not even apply to a borrower resident in Switzerland or Singapore — why the rejection? Because the refusal usually has nothing to do with §503 BGB. It is the shortest reason to hand, not the correct one.
- Sanction risk: a lender that breaches the foreign-currency rules faces a reduction of the interest rate and a penalty-free right of termination for the customer under §505d BGB — years after the contract was signed. One loan earns a modest margin; the mistake costs a multiple of it. With that asymmetry, credit risk departments decline.
- Applicable law: with residence in a third country, it is not always clear to the bank whether German or foreign consumer law governs the contract — and what applies on enforcement. This is the real sticking point in US cases.
- Process, not creditworthiness: identification without PostIdent, service of documents abroad, a German settlement account, anti-money-laundering checks. Most of it is solvable — just not in a branch’s standard process.
- Internal country lists: since 2016 many lenders have drawn their credit policies narrowly (“EU residence + euro income”). The adviser is then not permitted to assess the case at all — it is closed before anyone opens §503 BGB.
- Foreign-currency haircut: where financing does happen, banks do not count foreign income in full but apply a safety margin. That shrinks the budget, but it is not an exclusion criterion.
The practical consequence: arguing against a rejection rarely pays. Approaching the lenders that have mapped this constellation into their process does. That is my work.
The second-residence lever — and what it costs
Because §503 BGB attaches to residence at the time of contract, and because §7 BGB allows more than one residence, an idea suggests itself: with a residence in Germany the national currency is the euro — so the euro loan is not a foreign-currency loan. Identification, service of documents and jurisdiction are solved along with it. From the bank’s perspective, the cross-border case becomes a domestic one.
A residence actually maintained in Germany establishes unlimited tax liability under §8 AO — that is, taxation of worldwide income. For an expat on a high foreign salary, a second home permanently available for use can also call into question their treaty residence under the applicable double taxation agreement. The route banks like best is therefore the most delicate one in tax terms. It needs to be calculated before it is taken — with a tax adviser, not with the bank.
The other routes that can work, depending on the case: a German property-holding company as borrower (no consumer loan then, worthwhile only from a certain size), euro income or euro assets within the meaning of §503(1) sentence 3, or raising capital against German property you already own.
