The Probability of a July Fed Rate Hike Has Tripled Over the Last Week -- Here's Why

The odds of a Federal Reserve rate hike at the July 28-29 FOMC meeting have jumped from 10.7% to 34.7% in one week, according to market pricing. Three catalysts are driving the shift: deteriorating U.S.-Iran peace talks that threaten oil flows through the Strait of Hormuz, Core PCE inflation running at 3.4%—the highest print since October 2023—and inflationary pressure from AI data center construction.

The repricing creates a direct headwind for equity markets, particularly the AI-driven rally in large-cap tech. Higher borrowing costs would increase the expense of debt-financed infrastructure buildouts that have powered recent gains in the sector. The SPY, which tracks the S&P 500, remains vulnerable to any hawkish pivot as rate-sensitive growth names carry heavy index weight.

The 24-percentage-point swing in rate-hike probability reflects a market that had grown comfortable with the Fed holding steady. That assumption is now under pressure as geopolitical risk intersects with sticky inflation readings above the central bank's 2% target.
