Buyers return to the prime rate: the public is betting on a rate cut, but what happens if it is delayed?

An Israeli borrower entering a branch today is increasingly choosing the track that moves with the Bank of Israel's decisions. In June, the share of the prime track reached about 21% of new loans, almost double the approximately 11% in June of the previous year. At the same time, the market broke a monthly record: in July, mortgages totaling 11.56 billion shekels were taken, and since the beginning of the year, about 68.7 billion shekels have accumulated, about 13% above the corresponding period last year.

Whoever chooses prime buys direct exposure to the Monetary Committee. The Bank of Israel interest rate has stood at 3.5% since the beginning of July, after three cuts of a quarter of a percentage point since the beginning of 2026, and the prime rate is derived from it with an addition of 1.5% and stands at 5%. A borrower who locked in prime minus 0.9 pays 4.1% today on that component. The calculation on the positive side is simple: one million shekels for 25 years at 4.1% interest generates a monthly payment of about 5,334 shekels. Every quarter of a point that drops subtracts about 140 shekels from this amount. The three cuts already carried out this year are worth about 425 shekels a month to someone who held prime throughout the period, meaning close to 5,100 shekels a year. This is the amount the public saw in their bank account, and this is the reason the track doubled its share within a year.

And what happens if the next cut is delayed? The mechanism works at the same speed even when the direction reverses. The first scenario is a halt: the interest rate remains at its current level, the payment freezes in place, and the savings the borrower already priced for themselves simply evaporate. A family that built on two additional cuts in the coming year expected about 280 shekels a month to be reduced from the payment, about 3,400 shekels a year, and such an amount disappears without the payment rising by a single shekel.

The second scenario is sharper. A quarter of a point that rises adds about 140 shekels a month on a million shekels for 25 years, half a point adds about 280 shekels, and a whole point jumps the payment by about 571 shekels. The accumulation is the main thing: that same single point, from 4.1% to 5.1%, generates over 25 years an additional accumulated interest of about 171 thousand shekels. In a mortgage of one and a half million, it is about 857 shekels a month and about 257 thousand shekels over the period.

In the forecast published by the Bank of Israel's research division in the July decision, the economy is expected to grow by 4% in 2026 and by 5.5% in 2027, and inflation is expected to be about 1.8% during the year. The Monetary Committee repeatedly emphasizes that the interest rate path will be determined according to the development of inflation, economic activity, fiscal policy, and geopolitical developments, and less according to a pre-determined schedule. A strong growth forecast and a tight labor market are exactly the factors that can slow the pace of cuts.

In the world, the picture has already moved away from a scenario of consecutive cuts. In the July decision, the Bank of Israel noted that market pricing in the USA embodied one interest rate hike during the coming year and a chance of about 50% for another hike, and in Europe, the market embodied one hike. In August, the message in the bond markets sharpened: a tender of 30-year US government bonds closed at a yield of 5.216%, the highest since 2001, against the background of government deficits and large recruitment volumes. Monetary policy in Israel has a pace of its own, and a falling local interest rate can certainly exist alongside rising yields abroad.

The influence comes indirectly. The cost of recruitment for banks and government bond yields are what price the fixed interest rate in a mortgage, and therefore, protection against an interest rate hike becomes more expensive exactly when the world demands a higher yield. The exact same loan separates between fixed and variable by a gap of 835 shekels a month, and this gap moves with the markets.

How much of the mortgage is allowed to be loaded onto prime? Bank of Israel instructions limit the size of the bet. The prime component can reach up to two-thirds of the total mortgage, and at least one-third must sit on a fixed shekel interest rate. This limitation also defines the limit of actual exposure: on a mortgage of one million shekels with 666 thousand shekels in prime, a quarter of a point is worth about 93 shekels a month and a whole point about 380 shekels. Someone holding about 21% prime, the average for June, feels a quarter of a point as only 30 shekels.

Three ways to spread a million shekels between the tracks illustrate how much the result changes according to the composition, long before talking about an interest rate forecast. A gap of 1.4 points between the linked and the shekel. The escape from CPI-linking is the other side of the same move. In data published by the Bank of Israel in mid-July, the average interest rate in the fixed shekel track for a period of more than 20 years ranged around 4.8% to 4.9%, and in the fixed track linked to the index around 3.4% to 3.5%. The gap looks like a discount, and in practice, it is the price the bank charges for the inflation risk that passes to the borrower. The principal in the linked track grows with the consumer price index, so a 1% rise in the index inflates both the balance and the payment. Inflation in Israel stands at 1.5% in the 12 months ending in July, after the July index rose by 0.3%. At such a level, a significant part of the gap between the tracks is offset, and whoever moves to prime replaces one risk with another. Instead of committing to the rate of price increases over 25 years, he commits to the rate at which the Monetary Committee changes direction eight times a year.

The interest rate gaps between the banks accumulate to more than 100 thousand shekels in a large mortgage, even before touching the question of the mix. How much does it cost to change a mix halfway? For those who are already paying, there are three actions. The first is refinancing, meaning replacing the existing loan with a new one under today's conditions. The feasibility depends on the gap between the old and new interest rate, the remaining period, and the fees accompanying the move. When is mortgage refinancing worth the move and when is it just moving money in cases where the gap is large and the remaining period is long, and in other cases, the savings are swallowed by costs. The second is re-splitting the mix, usually transferring part of the prime component to a fixed interest rate. Fixing costs money already in the first month: someone paying 4.1% today and locking in a fixed shekel interest rate around 4.85% adds about 425 shekels a month to themselves on a million shekels, exactly the amount that the three cuts of the year saved them, and receives in return a pre-known payment for the entire period. The third is a partial exit from an existing track, and here early repayment fees enter, the amount of which is derived from the type of track and the gap between the interest rate on the loan and the average interest rate in the economy. In the prime track, this fee is minimal, and in a long fixed track, it can reach tens of thousands of shekels.

The right move is determined according to the borrower's own data. A household where the payment takes up a large share of the monthly income absorbs an addition of 400 or 500 shekels quite differently from someone who has breathing room. The remaining period determines how much of the addition will accumulate in practice, and the size of the balance determines the sensitivity to every quarter of a point. The larger the balance and the more years, the more it is worth paying today for certainty. Meanwhile, the numbers point in two directions at once: in Israel, three interest rate cuts since the beginning of the year and inflation of 1.5%, and in the world, a 30-year American bond tender that closed at the highest yield in 25 years. The next interest rate decision of the Monetary Committee will be published on September 1st, and every quarter of a point in it is worth about 140 shekels a month for someone who took a million shekels of prime for 25 years.
