Judgment Interest and CPI Linkage in Israel: How Court Debt Grows After a Verdict

Most countries set a flat post-judgment interest rate and leave it at that. Israel does not. Since 1961, the default rule has been CPI linkage plus interest: the principal grows with inflation each month, and a real interest rate accrues on top of the already-inflated figure. The combined effect, over the years it sometimes takes to collect a debt in Israel, can meaningfully change what is actually owed.

For a foreign creditor who obtained an Israeli judgment two years ago and is now trying to enforce it through the Execution Office, understanding this mechanism matters for calculating what the debtor currently owes, negotiating settlement, and distributing proceeds correctly. For a debtor — including an Israeli individual or company that owes money to a foreign party — it matters for understanding how fast the obligation is growing and why waiting is expensive.

This guide covers the statutory framework, how the CPI adjustment is calculated in practice, what happens with foreign currency judgments, and the practical steps for working out the current balance of an Israeli judgment debt.

1. The Governing Law: Adjudication of Interest and Linkage Law 5721-1961

The Adjudication of Interest and Linkage Law 5721-1961 (Chok Psakei Ribit VeHatzmada) is the foundation for all interest and CPI linkage on civil money judgments in Israel. It applies to judgments issued by Magistrate Courts, District Courts, and the Supreme Court. Arbitration awards are covered by a parallel track under the Arbitration Law 5728-1968 once the award is made enforceable by a district court order, at which point the judgment interest and linkage rules apply.

The law distinguishes between two periods: the pre-judgment period (from the date the debt became due to the date of the verdict) and the post-judgment period (from the date of verdict to actual payment). Different rules govern each.

Section 2 of the law gives courts explicit authority to award interest and linkage for the pre-judgment period. Section 1 makes post-judgment linkage and interest mandatory — the court has no discretion to exclude them once a judgment is issued for a money sum. The specific interest rate is set by a regulation issued by the Minister of Finance under Section 1A, which has been amended multiple times over the decades as market conditions changed.

The Central Bureau of Statistics (Lishkat HaStatistika HaMerkazit, CBS) publishes the CPI figure on or around the 15th of each calendar month. The linkage calculation uses the change in the index between two points in time — the judgment date (or the date a specific sum became due) and the payment date.

2. Pre-Judgment Interest: From Cause of Action to Verdict

The pre-judgment period runs from the date the debt first became due — typically when the contract was breached, the loan fell overdue, or the tortious act occurred — to the date the court issues its judgment. Courts have discretion under Section 2 of the law on whether to award interest and linkage for this period and, if so, from what date.

In practice, Israeli courts routinely award pre-judgment interest and CPI linkage when the plaintiff requests it. Courts rarely decline without a specific reason. The typical award runs from the date the debt became due, or from the date legal proceedings were filed if the exact due date is disputed. Where the plaintiff delayed bringing the claim without good reason, a court may shorten the pre-judgment interest period as a penalty for delay.

The interest rate for the pre-judgment period follows the same statutory rate that applies post-judgment, unless the parties had a contractual interest rate in their agreement. If the contract specified a higher rate (say, 24% per annum), the court may award the contractual rate for the pre-judgment period instead of the statutory default — and must do so if the contractual rate is lower than the statutory rate, since the statutory rate sets a floor.

This period matters enormously in cases that drag through the courts. Israeli civil litigation at the District Court level can take three to six years, sometimes longer. A NIS 500,000 dispute that runs for five years with CPI linkage and interest accruing the whole time arrives at judgment as a materially larger number than the original claim.

3. Post-Judgment Interest: The Mandatory Rate

Once a judgment is issued, the situation changes. Post-judgment interest and CPI linkage under Section 1 of the law are automatic and mandatory. The debtor cannot contract out of them, and the court has no authority to exclude them from a money judgment.

The statutory post-judgment interest rate is set by ministerial regulation and has been revised periodically. The rate is expressed as an annual percentage above the CPI linkage — that is, it represents a "real" return to the creditor over and above the inflation adjustment already built into the linkage. The Execution Office applies the current published rate when calculating the balance due on a file, updating it each time the Minister of Finance issues a revised regulation.

One practical consequence: if you have an old judgment and you want to know the current balance, you cannot simply look at the judgment amount. You need the CBS CPI indices for each month since the judgment date, the applicable statutory interest rate (which may have changed over the years), and the compounding method. The Execution Office maintains an internal calculation tool, but the creditor's attorney should independently verify the figure.

For judgments in NIS, the accumulated debt is always in NIS — the linkage mechanism adjusts the NIS figure upward, but does not convert the currency. For judgments in foreign currency, see Section 5 below.

4. How CPI Linkage Works Month to Month

CPI linkage (hatzmada laMadad) means the judgment principal is multiplied by the ratio of the current CPI to the CPI at the judgment date. If the CPI has risen 15% since the judgment was issued, the principal has grown by 15% before a single shekel of interest is added.

The CBS publishes one CPI figure per month (the monthly average). For linkage purposes, the calculation uses the index of the month immediately preceding the judgment date and the index of the month immediately preceding the payment date — not the exact judgment date and payment date, because the monthly index is a single number for the whole month. This one-month lag is built into the standard calculation.

The formula looks like this:

Linked Principal = Original Principal × (CPI at payment month / CPI at judgment month)

Interest then accrues annually on the linked principal at the statutory rate, calculated on a daily basis and added to the principal. The combined effect compounds over time: a higher principal each month means more interest accruing on that higher base.

During periods when Israel's inflation is low — as has been the case in some years — the linkage increment is modest and the statutory interest dominates. During high-inflation periods, linkage can add a more significant percentage in a single year. Parties to Israeli commercial contracts often attempt to cap or eliminate CPI linkage by contract, but this only applies to the pre-judgment period; post-judgment linkage under the statute cannot be contractually excluded.

5. Foreign Currency Judgments: Different Rules Apply

Israeli courts regularly issue judgments denominated in foreign currencies — USD, EUR, GBP — particularly in commercial cases involving international contracts or real estate transactions priced in foreign currency. The linkage mechanism works differently for these judgments.

A judgment denominated in USD or EUR does not receive CPI linkage in the Israeli sense. The logic is that the foreign currency itself is a partial inflation hedge (or at least an exposure to different monetary conditions), and double-indexing would be inappropriate. Instead, foreign currency judgments typically carry interest at a rate referenced to international benchmarks — historically LIBOR for USD judgments, though the SOFR transition has affected how this is calculated in recent years. The applicable rate is set by the same ministerial regulation that governs NIS judgments, but the foreign currency table differs from the NIS table.

When enforcing a foreign currency judgment through the Execution Office, the amount owed on any given day is calculated by: (1) computing the accumulated foreign currency debt including applicable interest; (2) converting to NIS at the Bank of Israel representative exchange rate published for that day. That conversion rate changes daily, meaning the NIS-equivalent amount of the debt fluctuates with currency movements entirely separately from any statutory interest or linkage mechanism.

For foreign creditors holding USD-denominated judgments against Israeli debtors, this creates two layers of variability: the interest accruing on the USD principal, and the NIS/USD exchange rate on the day the Execution Office actually distributes proceeds. Where possible, creditors enforcing foreign currency judgments should coordinate the timing of collections with their legal and financial advisors to minimize adverse currency exposure.

6. Calculating the Running Total of an Israeli Judgment Debt

Getting the current balance right matters on both sides of the dispute. A creditor who under-calculates the debt leaves money on the table in settlement. A debtor who over-pays cannot easily recover the excess. The Execution Office will compute the figure when the file is opened, but verifying that calculation independently is good practice.

The steps for calculating the current balance of a NIS-denominated judgment:

1. Identify the judgment date and the original NIS amount from the court decision.
2. Pull the CBS CPI index for the month immediately before the judgment date and for the month immediately before today.
3. Compute the linkage multiplier: divide the current-month index by the judgment-month index.
4. Apply the multiplier to the original principal to get the linkage-adjusted principal.
5. Add accrued statutory interest: apply the applicable annual rate (or rates, if the regulation changed during the accrual period) to the linked principal for each sub-period, on a daily basis.
6. Add any court-awarded legal costs (attorneys' fees, court filing fees) that were also subject to linkage and interest from the judgment date.
7. Deduct any partial payments the debtor has already made, attributed first to interest and costs, then to principal.

Where a judgment has been partly satisfied — say the creditor collected on a salary attachment for 18 months — the calculation involves multiple deduction events, each of which resets the accruing base. This is where errors creep in, and where the Execution Officer's running record of the file is the most reliable starting point, even if you verify it independently.

7. Settlement Timing and the Interest Clock

The interest clock never stops voluntarily. It runs until actual payment reaches the Execution Office file, or until the creditor formally withdraws or suspends the file. From a negotiation perspective, every week of delay costs the debtor more — and that asymmetry is one of the creditor's most effective tools in settlement discussions.

When the parties reach a settlement, the agreement should specify the cut-off date for interest and linkage calculations, the exact NIS amount to be paid (rather than a formula), and what happens to the Execution Office file. A common structure is for the parties to agree on a "settlement date balance" calculated by the creditor's attorney using the CBS indices as of that date, and for the debtor to pay that amount in exchange for the creditor withdrawing the Execution Office file with prejudice.

Tax considerations also arise here. Creditors who receive interest and linkage components as part of a judgment enforcement or settlement must report them for Israeli tax purposes. Interest income paid to a foreign creditor from an Israeli source is subject to withholding tax at source, typically 25% (or a reduced treaty rate where applicable). The CPI linkage component — the pure inflation adjustment — is generally not taxable as income, but the interest component above that adjustment is. This distinction should be built into any settlement agreement for a foreign creditor, since the Execution Office may withhold Israeli tax on the total amount distributed if the recipient's tax status is not properly documented.
