The US dollar just did something it hasn’t done since May 2025: climb to roughly 100.7 on the DXY index. The catalyst was a Federal Reserve meeting that didn’t actually change interest rates, but changed everything about how traders think rates will move from here.

On June 17, 2026, the Fed held the federal funds rate steady at 3.50%-3.75% for the fourth consecutive meeting. That part was expected. What wasn’t expected was the dot plot, where 9 of 18 to 19 officials now anticipate at least one rate hike before year-end. The Bloomberg Dollar Spot Index jumped 0.7% in response, its strongest single-session performance since early March.

From rate cuts to rate hikes in a matter of weeks

The Personal Consumption Expenditures inflation forecast, the Fed’s preferred price gauge, was revised from 2.7% to 3.6% for 2026. GDP growth expectations, meanwhile, were trimmed slightly to 2.2%.

Markets responded exactly how you’d expect. Traders rapidly repriced rate expectations, moving from bets on cuts to pricing in a 40% to 70% probability of a rate hike by year-end. October is the meeting most traders have circled on their calendars as the likely moment for action.
