United States experiences its first government shutdown in nearly seven years, the US dollar is seeing its longest period of decline in a month. Historical data shows that government shutdowns typically put pressure on the US dollar, and the options market is reflecting this trend. The Risk Reversal Index (used to measure the gap between demand for bullish and bearish trades) indicates that the US dollar faces further downside risk in the next month. Mohit Kumar, Chief European Strategist at Jefferies, stated that while stock market declines and increases in US Treasury bonds may be relatively mild, the "foreign exchange market is a market where we should not expect a reversal of the current trend," and he expects the weakening trend of the US dollar to continue. The duration of the government shutdown is crucial, as the longer it lasts, the greater the pressure on the US dollar. Since the beginning of this year, the US dollar has fallen to its lowest level since 2022, due to factors such as uncertainty in policies under the Trump administration, continuously expanding deficits, and the pressure on the independence of the Federal Reserve, all of which have raised concerns among investors.
