Global Tensions Bolster Dollar's Safe-Haven Appeal

The U.S. dollar held broadly steady on Monday, April 6, 2026, as investors weighed escalating conflict involving Iran alongside a new deadline set by U.S. President Donald Trump tied to the Strait of Hormuz. Market attention also focused on renewed pressure on the Japanese yen, which moved close to 160 per dollar, underscoring the currency’s sensitivity to risk sentiment and interest-rate expectations.

In a social media post, Trump said the United States would target Iranian infrastructure by Tuesday at 8 p.m. Eastern Time (0000 GMT) if the Strait of Hormuz is not reopened. The waterway is a critical route for energy flows and is described as handling approximately one-fifth of global oil consumption. The combination of a specific deadline and the strategic importance of the strait has kept geopolitical risk elevated in currency markets.

That backdrop has supported demand for the dollar as a safe-haven asset, even as major currency pairs showed only modest moves. The euro slipped 0.13% to $1.151, while sterling traded at $1.3187. The dollar index was at 100.2, reflecting a market that was cautious rather than disorderly as traders monitored developments around the Middle East conflict.

Energy prices remained a central channel through which the conflict is influencing markets. Brent crude has climbed above $110 per barrel since the U.S.-Israel war with Iran began in late February, a move that has intensified inflation concerns and reshaped expectations for monetary policy. Economists now expect the Federal Reserve will not cut rates until the second half of 2027, marking a sharp change from earlier forecasts that pointed to two cuts in 2026.

In Japan, the yen weakened to 159.77 per dollar, a level that has increased vigilance for possible intervention by Japanese authorities. However, the source material notes doubts about how effective intervention would be in the face of strong demand for the dollar. The yen’s slide highlights the tension between domestic policy constraints and global forces that can dominate exchange rates during periods of heightened uncertainty.

While a calm U.S. labor market report for March offered some reassurance, concerns remain about the broader economic consequences if the Middle East conflict becomes prolonged. The key unknown for markets is whether the situation around the Strait of Hormuz changes by the stated deadline, and how any further escalation could feed through oil prices, inflation expectations, and the path of interest rates globally.
