Iran War Spurs Debate Over Expanding U.S. Central Bank Swap Lines

Amidst the Iran war, U.S. allies like the UAE are requesting permanent access to unlimited U.S. dollar swap lines from the Federal Reserve. This is an unusual request, as the UAE is not among the major central banks that typically have such arrangements due to deep financial interconnectedness with the U.S. These permanent swap lines, currently held by Canada, Switzerland, the U.K., Japan, and the European Central Bank, allow central banks to access dollars in emergencies, ensuring financial stability. Extending such a line to the UAE on geopolitical grounds would be unprecedented for the Fed, which usually operates independently. This raises questions about who controls the Federal Reserve's multi-trillion-dollar assets. The UAE has suffered significant economic damage from Iranian attacks, and a swap line would be seen as a prestigious token of U.S. support. However, this financial diplomacy could alienate other allies like Saudi Arabia, who might also seek similar access. The decision rests with the Fed, not the Treasury, and the Fed has not commented. While traditionally asserting its exclusive authority, some, like Fed chair nominee Kevin Warsh, suggest the Fed should consider broader foreign policy implications in such decisions.
