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

The exchange rate between the US dollar and the Israeli shekel operates under a floating system, determined continuously by supply and demand in the global foreign exchange market rather than by any fixed price set by an authority. The most significant long-term driver of the dollar-shekel rate is the interest rate differential between Israel and the United States, alongside factors such as geopolitical stability, daily commercial currency 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 real-time trading among banks, corporations, funds, and private investors worldwide. When demand for dollars rises, for example due to Israeli entities purchasing assets abroad, the dollar strengthens against the shekel. Conversely, when demand for shekels increases, such as when Israeli tech companies convert dollar revenues to shekels, the shekel appreciates.

The interest rate gap between the Bank of Israel and the US Federal Reserve is crucial: capital tends to flow toward currencies offering higher returns. When US rates exceed Israeli rates, investors favor holding dollars, boosting its value against the shekel. Changes in this gap often precede shifts in the exchange rate. Additionally, the shekel is sensitive to security and political uncertainties; during times of conflict or instability, investors seek the perceived safety of the dollar, weakening the shekel.

Daily commercial activities also influence the rate. Importers require dollars to pay foreign suppliers, creating steady dollar demand, while exporters, especially in the tech sector, convert dollar income to shekels, supporting the shekel's strength. Institutional investors managing trillions of shekels, including pension funds and insurance companies, can cause sharp exchange rate movements when adjusting their foreign market exposures, sometimes causing sudden dollar surges unrelated to local economic changes.

Contrary to common belief, the Bank of Israel does not set the exchange rate but may intervene occasionally to moderate extreme volatility by buying or selling dollars. The official representative rate published daily by the Bank serves mainly for contracts and accounting and differs from the actual transaction rates, which include conversion fees and fluctuate throughout the trading day.

For individuals earning in dollars, such as freelancers or employees of foreign companies, exchange rate fluctuations directly affect their shekel income. Common strategies to mitigate volatility include gradual currency conversion over time and comparing conversion fees across providers. Overall, the dollar-shekel rate reflects a complex interplay of global financial conditions, interest rates, geopolitical events, and institutional capital flows rather than any single determining factor.
