US-Iran Tensions Drive Treasury Yield Volatility and Oil Price Swings
In late June 2026, President Trump signaled easing US-Iran tensions over the Strait of Hormuz, causing the 30-year Treasury yield to drop to 4.85% and oil prices to fall. However, on July 8, Trump declared the ceasefire "over," triggering a sharp reversal: bond yields surged (10-year Treasury to 4.59%, UK gilt to 4.957%), oil prices jumped above $80/barrel, and stocks fell amid renewed inflation fears and potential Fed tightening.

Treasury Yields Surge as Oil Rally Spurs Inflation Fears After Trump Revives Hormuz Blockade
U.S. Treasury yields rose sharply on July 13, 2026, as oil futures rallied nearly 10% after President Trump revived the naval blockade in the Strait of Hormuz and announced a 20% charge on cargo. The escalation in Middle East tensions reversed earlier expectations of declining energy costs from peace talks, fueling inflation concerns and boosting bets on Federal Reserve interest rate hikes. The two-year Treasury yield reached 4.261%, its highest since February 2025, while the 10-year yield rose to 4.610%. The WSJ Dollar Index gained 0.2%. Market focus now turns to upcoming CPI data and Fed Chairman Warsh's first congressional testimony, as analysts assess whether the oil shock will feed into inflation data or tighten financial conditions through sentiment.

Yahoo Finance30-Year Treasury Yield Falls to April Low on Trump Iran Signal
On June 24, 2026, the US 30-year Treasury yield dropped to 4.85%, its lowest since April 15, following President Donald Trump's signal of easing tensions with Iran over the Strait of Hormuz. Trump posted on Truth Social that Iran confirmed no tolls on shipping through the strategic waterway, which carries about a fifth of the world's oil. This led to falling oil prices, with WTI approaching $70 and Brent near $74, reducing near-term inflation fears and boosting demand for long-dated government debt. The decline reversed much of a spring selloff that had pushed the yield above 5.19% in May. However, the bond rally contrasts with the Federal Reserve's hawkish stance under new Chair Kevin Warsh, who projects a potential rate hike by end of 2026 amid 3.6% inflation. The 2-year yield remains above 4.2%, indicating a split curve. Lower long-term yields have eased mortgage rates to 6.47%. Investors await Thursday's inflation report, with volatility expected from competing Fed and geopolitical risks.
