U.S. government bond prices declined, driving 10- and 30-year yields to their highest in roughly two months, as rising crude oil prices revived fears that the Federal Reserve might increase rates to curb inflation.
On Tuesday, yields climbed approximately two to four basis points across various maturities. Meanwhile, the U.S. dollar gained against most major currencies as the U.S. and Iran continued a tenth day of strikes.
Rates strategist Izaac Brook at RBC Capital Markets stated: "Today's move is largely just a function of the continued rise in energy prices." He added that the upward move was amplified by the breach of key technical thresholds - specifically, two-year yields crossing 4.20% and the 10-year surpassing 4.60% - along with typical low-volume summer trading.

Ten- and thirty-year Treasury yields have reached their highest levels since May.
The recent selloff in bonds erased the gains from a rally that came after a weaker-than-expected inflation report earlier this month.
Natixis Chief U.S. Economist Christopher Hodge remarked: "As we have seen, energy prices have been volatile and realized data - not just projected headline CPI moves - should dominate the Fed's decision making calculus." Christopher Hodge added, "the Fed's reaction function under its new leader is far from certain."
For long-term bonds, some of the price drops stemmed from higher so-called real yields, which exclude inflation. The yield on 30-year Treasury Inflation-Protected Securities reached 2.95% earlier, a level not seen since 2008. Additionally, the market's movement has been amplified by trading volumes that are below normal. Data from CME Group's open-interest figures show that on Monday, trading volumes for Secured Overnight Financing Rate futures and options reached only 74% and 54% of their respective 20-day averages.
The ongoing conflict between the U.S. and Iran has disrupted supply chains in the Middle East, contributing to the persistent rise in crude prices. Analysts warn that if tensions escalate further, oil could push past $100 per barrel, intensifying inflationary pressures and potentially forcing the Fed to reconsider its current stance. Higher yields raise borrowing costs for consumers and businesses, slowing economic growth and making mortgage rates less affordable for homebuyers.
The surge in yields reflects mounting concerns that persistent energy-driven inflation could force the Fed to maintain or even tighten monetary policy, despite recent signs of economic cooling. The 30-year TIPS yield reaching 2.95%, a level not seen since 2008, underscores the market's expectation that inflation will remain elevated, complicating the central bank's path forward. With oil prices hovering near $92 a barrel and geopolitical tensions unresolved, bond traders are bracing for continued volatility.
The spike in long-term real yields signals that investors anticipate stubborn inflation regardless of the Fed's previous rate increases. This places the central bank in a tight spot: easing too soon could reignite price pressures, while maintaining restrictive policy risks a deeper economic slowdown. Meanwhile, the geopolitical turmoil in the Middle East adds an unpredictable supply-side shock, making the Fed's job even harder as it balances growth and price stability.
