Kurssikring (rate lock)

Kurssikring (a fastkursaftale) locks the bond price of your mortgage until an agreed date, usually completion day. It fixes the rate and payout of the loan no matter how prices move while you wait for the deal to complete.

The bond price can change from when you accept the loan to when the deal is final. Without a rate lock you risk the rate drifting away from you while you wait.

Kurssikring works like insurance: you pay a small fee or price deduction for certainty about the rate and proceeds.

It matters especially when there is a long time to completion, or when you choose a fixed rate, where even small price swings move the payment noticeably.

Ask your bank or mortgage institution whether a rate lock makes sense in your situation and what the agreement costs for the period you need.
