Currency Market Overview

At 15:53 ET (19:53 GMT) the U.S. dollar index, which measures the greenback against six major peers, was up 0.1% at 99.96, hovering close to the two‑month high of earlier this week. The modest rise reflected a tug‑of‑war between heightened safe‑haven demand amid escalating Iran‑related tensions and positive interest‑rate cues from a consumer‑price report that was only marginally softer than expected.

U.S. Consumer Price Index (May 2026)

The U.S. government released the May CPI data showing headline inflation rising 0.5% month‑on‑month and 4.2% year‑on‑year, both in line with economists’ forecasts. Core CPI, which excludes food and energy, increased 0.2% month‑on‑month and 2.9% year‑on‑year, also matching expectations. Both headline and core measures decelerated from April on a month‑on‑month basis.

Energy components were the dominant driver: energy prices jumped 23.5% year‑on‑year and gasoline surged 40.5% year‑on‑year, the strongest readings since August 2022 and July 2022 respectively, accounting for more than 60% of the headline CPI rise. Core goods inflation slipped 0.1% month‑on‑month, indicating a slight easing in commodity‑price pressures.

Market Reaction and Fed Outlook

The softer core reading prompted traders to slightly reduce expectations for further Federal Reserve rate hikes this year. Using the CME FedWatch tool, the probability of a quarter‑point rate cut rose modestly, while the odds of an additional hike fell compared with the pre‑report levels that had been elevated after strong labor‑market data the previous week. Higher interest‑rate environments typically support the dollar, but the muted core inflation tempered that effect.

Bill Adams, chief U.S. economist at Fifth Third Commercial Bank, commented that the softness in core goods prices suggested businesses were absorbing higher input costs within narrower margins and that tariff‑related price spikes were likely a one‑off shock that may have peaked. He also noted that gasoline prices were expected to ease in June, which could help the next CPI reading if the trend persisted.

Federal Reserve Decision

The Federal Reserve is slated to announce its first interest‑rate decision under new chair Kevin Warsh next week, a meeting that will be closely watched for any shift in policy stance.

Geopolitical and Policy Developments

In parallel, U.S. military action against Iran intensified after a U.S. helicopter was shot down over the Strait of Hormuz. President Donald Trump pledged a second day of “hard” strikes, reiterating that Iran must pay the price and claiming that much of Iran’s military had already been eradicated by a joint U.S.–Israeli campaign. Trump also asserted that Iran had agreed to a nuclear‑non‑proliferation paper, though negotiations remained stalled.

Other Major Currency Moves

The Canadian dollar slipped slightly after the Bank of Canada kept its policy rate unchanged. The euro remained flat ahead of the European Central Bank’s anticipated rate hike. The Japanese yen stayed above the 160 per dollar threshold, a level that has previously triggered intervention, while Governor Kazuo Ueda was expected to miss the upcoming BoJ meeting due to hospitalization. Japan’s producer‑price index rose 6.3% year‑on‑year in May, exceeding forecasts and reinforcing expectations that the BoJ may continue normalising monetary policy.
