U.S. Treasury prices rise across the yield curve as investors adjust their expectations for Federal Reserve interest-rate hikes, following reports of a deal aimed at ending the Iran war. Multiple outlets report that the move in Treasuries reflects a shift in market pricing: traders dial back the likelihood or timing of further Fed tightening after the geopolitical development reduces perceived risks and influences macro expectations. The rally is described as broad-based across maturities, indicating higher demand for government bonds relative to other assets. While the reports focus on the market reaction and the change in rate-hike assumptions, they do not provide detailed figures for yields or specific changes to the Fed path. Overall, the coverage portrays the Iran-deal news as a catalyst that prompts a reassessment of interest-rate expectations, which in turn supports Treasury prices. The accounts are consistent in linking the Treasury rally directly to trimmed Fed hike bets after the Iran-related announcement.
