U.S. Explores Gulf Currency Swaps

The United States is considering offering currency swaps to allies in the Persian Gulf and Asia, utilizing the Treasury Department's Exchange Stabilization Fund (ESF) rather than Federal Reserve swap lines. This initiative, which does not require Congressional approval, aims to facilitate temporary currency exchanges, potentially with the United Arab Emirates (UAE) and other Gulf nations. The ESF, with a ceiling of just over $40 billion, was previously used for a $20 billion swap line with Argentina in 2025 and for bridge financing to Uruguay in 2002.

This approach provides the U.S. executive branch with flexibility but faces capacity constraints, especially if existing lines with Mexico ($20 billion) and Argentina ($9 billion) are fully utilized. While the immediate macroeconomic rationale for Gulf states, which are cash-rich and dollarized, remains unclear, geopolitical considerations may be a driving factor. The initiative could promote trade and investment with the U.S. and potentially align the UAE's economic interests more closely with Washington, particularly given recent shifts in OPEC dynamics.

Market speculation suggests the UAE may seek a permanent dollar swap line, which would not be constrained by the ESF's liquid assets of $23.5 billion in Treasury securities and $19.3 billion in foreign currencies. Such a permanent arrangement would provide greater certainty for dollar funding. The broader implications include potentially strengthening a dollar alliance in the Gulf, contrasting with Iran's use of alternative currencies for transactions.
