The Bank for International Settlements (BIS) has issued a cautionary alert regarding a potential surge in demand for U.S. dollars triggered by instability in the global foreign exchange (FX) swap market, currently valued at approximately $113 trillion.
This market predominantly involves short-term dollar-denominated liabilities held by funds and non-bank financial institutions, which are often kept off balance sheets and thus obscure the true leverage and risk exposure of these entities.
Hyun-Song Shin, head of BIS’s monetary and economics department, highlighted that if investors begin unwinding these FX swap positions amid heightened market volatility, a scramble for U.S. dollars could ensue.
Since these swaps require repayment in dollars despite investors holding other currencies such as euros or yen, a rapid need to roll over or settle these obligations would intensify dollar demand, potentially causing a sharp appreciation of the U.S. currency.
This warning comes in the context of recent market disruptions, including escalated trade tensions and tariff policies, as well as Moody’s downgrade of the U.S. sovereign credit rating from triple-A status due to rising government debt levels.
The unusual simultaneous decline in U.S. stocks, bonds, and the dollar itself suggests a possible strategic reassessment by investors regarding their exposure to U.S. assets.
For market participants, this scenario implies a need to reevaluate portfolio risk and hedging strategies, as a sudden dollar surge could significantly impact currency markets and asset valuations globally.
The BIS’s analysis underscores the fragility of current financial conditions and the potential for a rapid shift in liquidity dynamics driven by off-balance-sheet FX swap exposures.
