US real yields hit 2.3% as Iran conflict revives rate hike bets

The US 10-year inflation-protected Treasury yield climbed to about 2.3% Wednesday, the highest since April 2025, as a renewed escalation in the Middle East pushed oil prices higher and reinforced expectations the Federal Reserve may need to resume tightening.

"Real rates are being driven higher by solid growth expectations and the growing concern that the Fed may need to tighten further as the Middle East conflict escalates," said Gennadiy Goldberg, head of US rates strategy at TD Securities.

West Texas Intermediate crude rose toward $74 a barrel after President Donald Trump declared the Iran ceasefire "over" following tanker strikes in the Strait of Hormuz, a chokepoint handling about one-fifth of global petroleum consumption. The move reversed a decline that had taken oil below $68 after the truce was reached last month. Rate hike odds jumped to 68.8% for the September meeting and 85.3% for December, according to CME Group's FedWatch tool, up from 62% and 48% respectively a day earlier. The Dow Jones Industrial Average dropped about 570 points, or 1%, while the S&P 500 and Nasdaq fell 0.3% and 0.1%.

The repricing matters because higher real yields strengthen the dollar and increase the opportunity cost of holding non-yielding assets such as gold and cryptocurrencies, potentially triggering sell-offs in those markets. For equities, the shift in rate expectations adds pressure on growth and technology stocks most sensitive to higher discount rates, even as the AI investment boom provides some cushion to the broader economy.

The Federal Reserve held its benchmark rate at 3.5% to 3.75% at its June meeting, with minutes showing a divided committee. A "few" officials saw a case for hiking, while others viewed policy as too restrictive. "Many" participants expected rates to end the year "within or slightly below" the current range, but "many other" participants assessed rates would be higher. The central bank does not anticipate a cut before the second quarter of 2027, according to the minutes.

Oil's Transmission to Inflation

The renewed conflict threatens to undo the progress on inflation that had allowed the Fed to pause. Core consumer prices rose 4.2% in May from a year earlier, with gasoline costs surging 59% year-over-year, according to the Bureau of Labor Statistics. The Fed's preferred inflation gauge, the core personal consumption expenditures index, hit 3.4% in May, the fastest pace in nearly three years. If crude continues climbing from current levels toward the triple-digit prices seen earlier in the conflict, energy costs could feed through to a broader range of goods and services, forcing policymakers to choose between fighting inflation and protecting growth.

The last time the 10-year TIPS yield approached this level was in April 2025, when markets were pricing a more aggressive Fed tightening cycle. That period saw the S&P 500 fall about 5% over the following month as higher real rates weighed on equity valuations.

What Comes Next

The Fed's next meeting later this month is widely expected to leave rates unchanged. But the trajectory beyond that depends heavily on oil. If crude stabilizes near current levels, the inflation impulse may fade and allow the Fed to maintain its wait-and-see stance. If prices resume their climb toward $100, the case for a rate hike before year-end will strengthen considerably. For investors, the price of oil has reemerged as the single most important variable in the rate outlook.
