Israel's Dollar-Shekel Exchange Rate Driven by Interest Gaps and Market Forces

The exchange rate between the US dollar and the Israeli shekel is determined by a floating rate system, where supply and demand in the global foreign exchange market set the price continuously rather than any fixed authority. The most influential long-term factor shaping the dollar-shekel rate is the interest rate differential between Israel and the United States, alongside other elements such as security conditions, daily commercial flows from importers and exporters, and large capital movements by institutional investors.

Since Israel adopted a floating exchange rate regime, the dollar-shekel rate fluctuates based on market transactions involving banks, corporations, funds, and private investors worldwide. When demand for dollars rises, for example due to Israeli entities purchasing assets abroad, the dollar strengthens and the shekel weakens. Conversely, when demand for shekels increases, such as when Israeli high-tech companies convert dollar revenues into shekels, the shekel appreciates.

The interest rate gap between the Bank of Israel and the US Federal Reserve is a key driver: capital tends to flow toward currencies offering higher returns. When US interest rates exceed Israeli rates, investors prefer dollars, boosting its value against the shekel. This dynamic reverses if Israeli rates rise relative to US rates. Security and geopolitical tensions also impact the shekel, which is sensitive to uncertainty; during escalations or instability, investors favor the dollar as a safe haven, weakening the shekel.

Daily commercial currency conversions by importers and exporters, especially Israel's high-tech sector which brings in tens of billions of dollars annually, create steady demand for both currencies. Institutional investors managing trillions of shekels in pension funds and insurance also influence sharp short-term fluctuations by adjusting their foreign exposure, often reacting to US stock market movements.

Contrary to common belief, the Bank of Israel does not set the exchange rate but intervenes only occasionally to curb extreme volatility. It publishes an official reference rate once daily, which differs from the actual market rate used in currency conversions that include transaction margins. For individuals earning income in dollars, exchange rate fluctuations directly affect their shekel earnings, making gradual currency conversion and comparing conversion fees advisable strategies.

In summary, the dollar-shekel exchange rate is a complex interplay of global market forces, interest rate differentials, geopolitical factors, and institutional capital flows, with the Bank of Israel playing a limited stabilizing role rather than price-setting.
