US Dollar Edges Higher as Inflation Data and Middle East Tensions Shape Market Sentiment

The U.S. dollar posted modest gains on Wednesday as investors weighed mixed signals from inflation data alongside escalating geopolitical tensions in the Middle East. The U.S. Dollar Index (DXY), which measures the greenback against six major currencies, rose 0.1% to 99.96, remaining close to a two-month high reached earlier this week.

Market attention centered on the latest U.S. Consumer Price Index (CPI) report for May. Data showed headline inflation increased by 0.5% month-over-month and 4.2% year-over-year, matching economists’ forecasts. Core CPI, which excludes food and energy prices, rose 0.2% monthly and 2.9% annually, slightly below expectations on a monthly basis and unchanged from forecasts year-over-year.

Although annual headline inflation reached its highest level since April 2023, much of the increase was driven by surging energy costs. Energy prices climbed 23.5% from a year earlier, while gasoline prices jumped 40.5%, largely reflecting disruptions linked to ongoing Middle East conflicts. Meanwhile, core goods prices declined 0.1% in May, indicating that underlying inflationary pressures remain relatively contained.

The softer core inflation figures prompted traders to slightly reduce expectations for additional Federal Reserve rate hikes and increase the probability of a quarter-point interest rate cut later this year. Analysts noted that businesses may be absorbing higher costs rather than passing them on to consumers, helping to moderate core inflation.

Geopolitical developments also influenced currency markets. Safe-haven demand increased after the United States conducted military strikes against Iran following heightened tensions in the Strait of Hormuz. President Donald Trump signaled further action against Iran, adding uncertainty to global financial markets and supporting demand for the U.S. dollar.

Elsewhere, the Bank of Canada left interest rates unchanged, while investors turned their focus to upcoming policy decisions from the European Central Bank and the Bank of Japan. The euro traded largely unchanged ahead of the ECB meeting, where markets expect another rate increase. The Japanese yen remained weak above the key 160 level against the dollar despite expectations that the Bank of Japan could raise interest rates next week. Stronger-than-expected Japanese producer price data further reinforced speculation that Japanese policymakers may continue normalizing monetary policy.

Currency traders will continue monitoring inflation trends, central bank decisions, and geopolitical developments as key drivers of global foreign exchange markets in 2026.
