A geopolitical flare-up in the Middle East is unwinding months of conviction that interest rates had peaked, forcing markets to price in a new era of inflation and central bank hawkishness.

Global bond rout deepens with US 30-year yield over 5%
A global bond market selloff intensified after tensions with Iran sent oil prices surging, pushing the U.S. 30-year Treasury yield past 5 percent for the first time since 2007 and prompting traders to price in a renewed cycle of Federal Reserve rate hikes.
"We are seeing a world that is really grappling with another bout of inflation," said Karen Manna, a fixed-income strategist at Federated Hermes, reflecting a market consensus that has shifted dramatically in recent weeks.
The 30-year yield jumped more than 10 basis points to 5.12 percent, while the benchmark 10-year note yielded 4.58 percent. The moves came as wholesale prices were shown to have risen 6 percent in April, the fastest since January 2023, flipping expectations from two rate cuts in 2026 to a 36 percent chance of a hike by December, according to CME Group data.
The violent repricing in the bond market presents a major challenge for incoming Federal Reserve Chair Kevin Warsh and G7 finance ministers, as persistently higher borrowing costs threaten to stifle economic growth and add pressure to a U.S. government facing a ballooning deficit.
War Risk Premium Reshapes Rate Outlook
The core driver of the bond rout is the blockade of the Strait of Hormuz, a critical channel for global oil transport. The risk of a wider conflict with Iran has injected a persistent risk premium into energy prices, fueling concerns that inflation will prove more stubborn than anticipated. "Unless the strait reopens, the entire range for rates has shifted higher," noted Priya Misra, a portfolio manager at JPMorgan Asset Management.
This has led to a dramatic reversal in rate expectations. At the end of February, markets were pricing in two rate cuts for 2026. Now, traders see a rate hike by March of next year as a high-probability event. The U.S. Treasury has already had to offer a 5.05 percent yield on $25 billion of 30-year bonds—the highest since 2007—to attract tepid demand, a sign that investors are demanding higher compensation for holding long-term government debt.
Inflation Narrative Takes Hold
With the Producer Price Index at 6 percent and the Consumer Price Index at 3.8 percent and rising, the market's focus is now squarely on inflation. "The inflation narrative is taking over," said Kevin Flanagan, head of investment strategy at WisdomTree. He expects the next CPI report could show an annual rate of 4 percent, a level not seen since 2023.
The anxiety is visible in market positioning, with a recent JPMorgan survey showing net short positions in Treasuries at a 13-week high. The concern is that higher short-term rates, driven by the government's increasing reliance on bill issuance to fund its deficit, could work against the Fed's efforts to control price pressures. "Long end rates are now in control of monetary policy," wrote Peter Boockvar, chief investment officer of One Point BFG Wealth Partners.
