The conversion right §503 BGB explained
When does the conversion right apply — and when not? A central question for property financing when you live abroad. Here are the key rules at a glance.
What the conversion right §503 BGB is
The conversion right (§503 BGB) was introduced in 2016 with the EU Mortgage Credit Directive. It applies to foreign-currency loans — that is, when the loan runs in a different currency from the borrower’s income.
The core idea: if the exchange rate moves by more than 20 % to the borrower’s disadvantage, the borrower can demand that the bank convert the loan into the income currency. This protects borrowers from exchange-rate risk — but it is a considerable operational burden for banks.
When the conversion right DOES apply
- The borrower has residence in an EU member state
- Income in an EU currency that is not the euro — DKK, SEK, PLN, HUF, CZK, RON, BGN, HRK
- The loan agreement is a consumer property loan
When the conversion right does NOT apply
- Residence outside the EU — Switzerland, UK (post-Brexit), USA, UAE, Asia
- EU residence, income in euros — Netherlands, Austria, Italy, Spain
- Business loans (not a consumer)
Why the conversion right matters for Germans abroad
Banks must be able to implement the conversion right operationally — monitoring exchange rates, the conversion process, risk assessment. That is effort. Many smaller banks therefore reject borrowers resident in non-euro EU countries across the board.
A paradox: tax non-residents in non-EU countries (Switzerland, UK, USA) sometimes have it easier than borrowers from Poland or Sweden — because the conversion right does not apply.
Practical tips
- Residence Switzerland / UK / USA: no conversion right — a wider choice of banks
- Residence Poland / Sweden / Denmark: §503 BGB applies — only banks with an FX monitoring system
- Residence NL / Austria / Italy / Spain: income in EUR, no conversion-right issue
