What Are the Anchor and the Margin in a Variable-Rate Mortgage?

What the rate on variable tracks is made of, which anchors are common, and why the margin is the most important number to negotiate.

In every variable-rate track the interest rate is made of two parts:

Rate = anchor + margin

The anchor

The anchor is an external figure that the bank does not set, and it changes with the market. Common examples:

  • The Bank of Israel rate – the anchor of the prime track (through the prime rate).
  • Government bond yields – a common anchor for "variable every 5 years" tracks, linked and non-linked.
  • An average of rates published by the Bank of Israel – in some tracks.

The margin

The margin is the addition (or discount) the bank adds to the anchor. It is set on the day of signing and stays fixed for the whole life of the loan.

Why is the margin so important?

Because you cannot change the anchor, but you can lower the margin in negotiations. A 0.3% difference in the margin on NIS 500,000 over 25 years adds up to tens of thousands of shekels.

An example

Variable every 5 years, non-linked: the anchor on reset day is 3.6%, the margin is 0.8%. The rate for the next 5 years will be 4.4%.

Elia's tip: When comparing offers for a variable track, do not look only at the starting rate. Ask what the anchor and the margin are. A bank can offer a low starting rate with a high margin, and that will cost you dearly later.
