Key Takeaways
- Polymarket implies a 74.5% chance the Fed makes no rate change after the July 2026 meeting.
- Traders kept pricing steady even as markets weighed oil’s pullback after the interim U.S.-Iran deal and renewed talk from Fed officials that a hike later this year remains possible.

U.S. stocks climbed on Thursday, led by technology shares, as investors reacted to optimism around an interim U.S.-Iran peace deal and the latest Federal Reserve policy decision. The Nasdaq Composite jumped by nearly 2%, while the S&P 500 rose about 1.1% and the Dow added roughly 0.3%. President Donald Trump and Iran’s president signed a memo outlining the peace agreement, which included reopening the Strait of Hormuz to commercial traffic and removing a U.S. naval blockade in the region. Negotiations on longer-running issues, including Iran’s nuclear program, are expected over the next 60 days. In commodities, Brent crude hovered around $79 a barrel and West Texas Intermediate traded above $75 as crossings through the strait increased and oil gave back part of its conflict-driven gains.
