- What actually happens
- The monthly payment looks small and easy to pay at the start. That feels good. But this loan is connected to prices in the shops. When food, fuel and rent get more expensive in Iceland (this is called inflation), the bank quietly adds that extra cost on top of what you still owe. So you can pay the bank every single month, on time, for years, and one day check your balance and see that you owe more than the money they first gave you. You did nothing wrong. The loan just grew in the background while you were paying it.
- What to do
- Before signing an indexed loan, ask the bank to show you the principal balance projected forward year by year under a moderate inflation assumption. Make sure you understand that what you owe and what you pay each month are two different numbers.
- The common trap
- Choosing indexed purely because the monthly payment is lower. The low payment is real; so is the silent growth in the balance.
