Dollar hits one-year high as Fed signals rate hike; Japan turns to verbal intervention

The greenback surged to its strongest position in over a year after the Federal Reserve adopted a hawkish stance, sparking global currency volatility.

The U.S. dollar is flexing its muscles again, hitting a one-year high as markets recalibrate for a potential interest rate hike. Under new chair Kevin Warsh, the Federal Reserve opted for a hawkish hold, leaving rates in the 3.50% to 3.75% range. However, the accompanying policy review told a different story: nearly half of the policymakers are now leaning toward a hike before the year is out, driven by persistent inflation concerns.

A shift in market bets

Data from the Fed funds futures market suggests investors are now fully pricing in a hike by October. This hawkish turn was further emboldened by robust retail sales figures, which solidified the view that the U.S. economy remains resilient enough to absorb tighter monetary policy. The dollar index—a gauge of the greenback against a basket of currencies including the euro and sterling—climbed 0.7% to 100.79, marking its strongest performance since May 2025.

The impact has been immediate across the board. The euro slipped 0.3% to $1.146, while sterling took a harder hit, falling 0.6% to $1.321. Both currencies are now languishing at their lowest levels in more than two months. While the recent U.S.-Iran interim agreement—aimed at reopening the Strait of Hormuz—initially exerted some downward pressure on oil prices, it wasn't enough to curb the dollar’s momentum. As analysts at Everbright Securities note, until there is concrete confirmation that the Strait can function for free passage, the market will likely keep betting on the safety and strength of the greenback.

Japan’s currency dilemma

Across the Pacific, the Japanese yen is struggling to hold its ground, sliding to 161.41. This decline effectively erased the gains achieved after Tokyo’s intervention late in April. The currency’s weakness has sent a clear signal to Japanese officials, who are once again reaching for their "verbal intervention" toolkit. Chief Cabinet Secretary Minoru Kihara reiterated on Thursday that the government is ready to respond to currency moves as needed at any time, a thinly veiled warning to speculators betting against the yen.

The bigger picture

Why does this matter? The current strengthening of the dollar reflects a fundamental shift in how global markets perceive U.S. monetary policy. When the Fed moves toward a hawkish bias, capital tends to flow toward the dollar, putting immense pressure on other central banks to either match those moves or watch their own currencies lose value. For emerging economies, this "dollar dominance" often translates into imported inflation and tighter liquidity conditions. While markets occasionally buzz with questions about whether the U.S. market is closed today, the real story lies in the persistent, underlying demand for the dollar as the primary safe haven during times of global economic recalibration.
