The U.S. dollar has fallen to its lowest level in nearly four years, and the foreign-exchange market is bracing for the possibility of further declines. With U.S. policy uncertainty intersecting with a stronger yen, a view is spreading that dollar weakness could become a structural trend rather than a short-term correction.
On the 27th (local time), Bloomberg said the Bloomberg Dollar Spot Index posted sharp declines for a fourth straight day. It was the biggest drop since President Trump signaled sweeping tariff impositions. After turning in its worst performance last year, the dollar has failed to shake off its weak trend this year as well.
Foreign-exchange participants are paying record-high premiums in the options market to hedge against further selling. In the FX market, where daily transaction volume exceeds $9 trillion (about 1,260 quadrillion won), surging demand to bet against the dollar has driven option prices to the record high since related statistics began. This shows investors view the dollar's decline not as a short-term variable but as a major investment theme.
Dollar weakness has translated into broader strength across major currencies. The euro and the British pound rose to their highest levels in about four and a half years, and the yen also strengthened. After a government official in Japan hinted at possible market intervention to stabilize exchange rates, news that the New York Federal Reserve had asked financial institutions about the yen's exchange rate rekindled speculation about joint U.S.-Japan FX intervention. The yen climbed nearly 1% in New York, marking its biggest gain in recent months.
Markets say unpredictable U.S. policy decisions are putting persistent pressure on the dollar. President Trump's pressure on the Federal Reserve (Fed), a worsening U.S. fiscal outlook and mounting liability burdens, and deepening political polarization are combining to dampen sentiment toward U.S. assets across the board, according to assessments. Some experts noted the market has entered a phase where nontraditional factors are driving dollar weakness.
Rate expectations are also working against the dollar. While markets see the Fed holding rates steady for now, they are still pricing in two cuts within the year. That contrasts with other major Central Bank signals that point to a hold or further tightening. The nomination of the next Fed chair and the possibility of a federal government shutdown are also cited as factors eroding confidence in the dollar.
Emerging-market currencies are also benefiting from the weaker dollar. The emerging-market currency index has continued to rise, nearing an all-time high. With expectations for global growth intact, analysts say investors are increasingly seeking higher returns outside the United States.
Experts say that despite relatively solid U.S. economic data, damaged policy credibility is amplifying downward pressure on the dollar. The surge in transactions betting against the dollar in the options market suggests investors are largely treating the prospect of further declines as a given. In the market, the view is gaining traction that the dollar is likely to remain on a weak trajectory for the time being amid ongoing volatility.
