Treasury Secretary Scott Bessent confirmed that multiple Gulf and Asian nations have formally requested currency swap lines from the United States, citing economic stress linked to the Iran war. Swap lines allow foreign central banks to borrow US dollars directly from the Federal Reserve or Treasury, supporting dollar-denominated lending in their economies. The requests signal significant dollar liquidity stress spreading across two major economic regions simultaneously.
Demand for dollar swap lines is a strong vote of confidence in the dollar's role as the world's reserve currency — bullish for USD and dollar-denominated assets broadly. For equity investors, this raises the risk profile of emerging market and Gulf-exposed positions while reinforcing the relative safety of US Treasuries and dollar assets. It also signals that geopolitical stress from the Iran conflict is creating real financial contagion beyond the immediate region.
Watch for Federal Reserve announcements activating or expanding swap line agreements — these follow Treasury-level requests and could come within days to weeks. Monitor Gulf equity markets (Saudi Tadawul, UAE DFM) for signs of liquidity stress. Next US CPI report and any Federal Reserve emergency statements would be critical escalation signals.
