The Bank of Israel interest rate affects your mortgage through one clear channel: the prime rate, always defined as the Bank of Israel rate plus 1.5%. When the Monetary Committee raises or lowers the rate, at one of eight decisions each year, the prime track reacts almost immediately, variable-rate tracks update only at their scheduled reset points, and fixed-rate tracks do not move at all. How much a decision affects your monthly payment therefore depends on your mix. This guide explains the mechanism, what to check after each decision, when to consider refinancing, and how to build a resilient mix.

How the Bank of Israel Rate Decision Works

The Bank of Israel rate is the rate at which the central bank lends money to commercial banks, and it is the main tool of monetary policy. The Monetary Committee meets eight times a year, on a schedule published in advance, and decides whether to raise, lower, or hold the rate, based mainly on inflation and economic data. The decision does not touch your mortgage directly: it changes the cost of money in the economy, and commercial banks then reprice their credit, starting with the prime rate. Since the calendar is public, the only question at each date is direction and size.

The Prime Rate: Bank of Israel Plus 1.5%, Always

In Israel, the prime rate is not set separately by each bank. It is defined uniformly as the Bank of Israel rate plus a fixed margin of 1.5%, so every change in the central bank rate passes one-to-one into prime, in both directions.

A prime track in a mortgage is priced as prime plus or minus a personal margin agreed when you take the loan. The margin is fixed for the life of the loan; what moves is prime itself, which makes this the rate-sensitive component of your mix.

Which Tracks React to a Rate Decision, and Which Do Not

Not all of your mortgage is equally exposed, which is exactly why borrowers build a mortgage mix rather than taking the whole loan on a single track.

Track	When the rate changes	Reaction to a rate decision
Prime	Continuously, right after a Bank of Israel change	Immediate and full
Variable, unlinked	Only at preset reset points, for example every five years	Only at the next reset
Variable, CPI-linked	At reset points, plus CPI linkage on the principal	Only at the next reset, separately from CPI effects
Fixed, unlinked	Never	None
Fixed, CPI-linked	Rate is fixed, principal is CPI-linked	None to the rate, exposure to CPI remains

The key distinction: variable-rate tracks feel a decision only at their next reset point, while fixed tracks are locked, the rate you signed stays to the end, regardless of any future decision.

How a Rate Hike Flows Into the Monthly Payment: An Illustration

Take round numbers, for illustration only, not a reflection of market rates. Suppose your prime component is 400,000 NIS over 25 years at 4%: the monthly payment on it is roughly 2,110 NIS. If a quarter-point hike moves the track to 4.25%, the payment rises to roughly 2,170 NIS, about 60 NIS more per month on that component alone. Again, illustrative numbers only.

Three takeaways: a single decision usually has a moderate effect, tens of shekels rather than hundreds; the effect compounds over consecutive hikes; and a large prime share feels every decision more than a small one. The update appears within a payment cycle or two. Test your own numbers with our mortgage calculator.

What to Check in Your Mix After Every Rate Decision

A rate decision is a good reminder to run a short, orderly check, even when you end up changing nothing:

How much of your mortgage sits in prime and variable tracks. That number matters more than the headline.
Your new monthly payment. Know how much it rose or fell, instead of discovering it on a statement.
When the next reset point falls on your variable tracks.
Your payment-to-income ratio. If the payment strains the household's cash flow, review the structure now.
Whether a gap has opened between your rates and what is achievable today, the basis for a refinancing review.

The check takes half an hour, and it is the difference between managing a mortgage and being managed by one.

When a Rate Decision Is a Refinancing Trigger

A single rate decision is almost never a reason to refinance on its own, but it can be the moment you discover conditions have shifted enough to make a review worthwhile. A rate environment that has fallen since you took the loan, a mix built under very different conditions, or income that has changed, any of these can make refinancing the right move; in many cases, depending on your numbers, it lowers the monthly payment or shortens the term. We covered the full process in our guide to mortgage refinancing.

Refinancing also has costs: fixed tracks may carry an early repayment fee, which sometimes erases the benefit and sometimes is smaller than feared. Read our early repayment fee guide before deciding. A real feasibility check compares the total cost of the existing mortgage against the alternative, fees included, not just the monthly payment.

Why Not to Act in Panic After a Decision

After 19 years inside the banking system, I have seen it again and again: the day after a hike, borrowers call in a rush asking to "get out of prime now", and the day after a cut they ask to "move everything into prime". Both reactions make a long-term decision based on a single event.

Acting on a published decision means transacting at prices that already reflect it. Locking a fixed rate in a moment of stress can fix a high rate for years, and leaving prime after a hike gives up the benefit if the direction reverses. No one knows what the next decisions will bring, so sound mortgage decisions do not try to guess the next rate; they build a structure that holds up across scenarios. Changing your mix is legitimate, when it comes from planning rather than a headline.

Building a Rate-Resilient Mix

A resilient mix does not try to beat the rate; it tries not to depend on it. The principle: split the mortgage between a fixed component that provides certainty, a prime component that benefits from cuts and allows flexible early repayment, and sometimes a variable component between them. The right split depends on income stability, cash-flow sensitivity, early repayment plans, and how long you expect to hold the property.

This is exactly the work done in a structured mortgage consulting process: translating your numbers into a structure that fits you, and running different rate scenarios on the proposed mix before you sign, not after. We work with clients from Ness Ziona, Rehovot, Rishon LeZion and central Israel, and hold remote meetings nationwide.

Questions and Answers

How many times a year does the Bank of Israel decide on the interest rate?

The Bank of Israel's Monetary Committee makes eight rate decisions a year, on dates published in advance in an annual calendar. At each date it can raise the rate, lower it, or leave it unchanged, based on inflation and economic data. Deciding between scheduled dates is possible but rare.

What is the difference between the Bank of Israel rate and the prime rate?

The Bank of Israel rate is set by the central bank, and the prime rate is that rate plus a fixed margin of 1.5%. The formula is uniform across all banks, so every change passes fully into prime. Your prime-track mortgage is priced as prime plus or minus a personal margin set when the loan was taken.

Does a rate hike affect an existing fixed-rate track?

No. On a fixed-rate track, linked or unlinked, the rate set when the loan was executed stays unchanged for the entire term, and no future rate decision alters it. A hike affects the prime component immediately, and variable tracks at their next reset point. A CPI-linked fixed track remains exposed to inflation, but not to the rate.

How quickly does a rate change reach my monthly payment?

On the prime component the update is fast: banks adjust prime shortly after the decision, and the change appears in the next monthly payment or the one after, depending on your billing date. On variable-rate tracks it arrives only at the next reset point set in the loan agreement, which may be years away. Fixed tracks do not change.

Should I leave the prime track when rates rise?

Not automatically. Leaving prime after a hike means moving at terms that already reflect the hike, and it gives up flexibility and the benefit of future cuts. The right decision depends on the size of your prime component, your cash-flow sensitivity, and the overall mortgage picture. In many cases a measured rebalancing beats abandoning a whole track at once.
