Key Takeaways:
Yields on 10-year U.S. Treasuries, German Bunds and U.K. Gilts climbed to four-week highs Tuesday as renewed military escalation in the Middle East pushed crude oil prices more than 3% higher.
Yields on 10-year U.S. Treasuries, German Bunds and U.K. government bonds rose to four-week highs Tuesday as renewed U.S. strikes on Iran and attacks on vessels in the Strait of Hormuz pushed crude oil prices more than 3% higher, reigniting inflation fears that had been cooling.
"Higher oil means higher gasoline, higher shipping and higher everything," said James Hyerczyk, a U.S.-based technical analyst with more than 40 years of market experience. "That chain ran all week and it is still running."
The 10-year U.S. Treasury yield climbed to 4.631%, its highest since Feb. 12, while the 30-year bond yield rose to 5.159%, a level not seen since October 2023. Brent crude settled at $74.16 a barrel, up $2.17 or 3.01%, after Iran attacked three commercial vessels near the Strait of Hormuz, a chokepoint that handles about 21% of global oil trade. The U.S. revoked a license allowing Iran to sell oil and unleashed a new wave of strikes, escalating both military and economic pressure.
The cross-asset repricing threatens to delay any Federal Reserve rate cuts. Traders now see about a 56% chance of a rate increase in September, according to the CME FedWatch tool — a dramatic reversal from earlier this year when markets priced multiple cuts. If oil stays elevated above $74, the 10-year yield could test 5%, a level that last triggered broad equity selloffs across developed markets.
Oil's Transmission Chain
The mechanism linking Middle East violence to bond yields runs through inflation expectations. Brent crude has risen more than 10% since late June as tensions in the Strait of Hormuz escalated. Higher energy costs feed into gasoline prices, shipping rates and eventually core inflation readings. April inflation came in at 3.8%, hotter than expected, and three consecutive upside misses have pushed the rate-cut timeline further out.
The last time the 10-year yield traded above 4.6% in February, the S&P 500 fell 2.1% over the following two weeks as rate-sensitive sectors — real estate, utilities and technology — sold off. The U.S. Dollar Index, which recovered from a recent multi-month low of 97.625 toward the psychological 100 level, adds further pressure on emerging-market currencies and commodities priced in dollars.
European Bonds Follow Suit
German 10-year Bund yields rose to their highest in four weeks, tracking U.S. moves as the euro-area economy faces the same energy-price risk. The U.K.'s 10-year Gilt yield also hit a four-week high, compounding pressure on a British economy already grappling with sticky services inflation. The synchronised move across the three largest developed-market bond markets signals that investors see the oil shock as a global, not regional, risk.
Gold, which typically benefits from geopolitical turmoil, fell 0.5% to $4,144.36 an ounce as the dollar strength and rising real yields overwhelmed safe-haven demand. Spot gold briefly pierced the $4,481.78 level Monday — the 20% threshold below its all-time high that separates bull from bear market by classic technical analysis — before bargain hunters stepped in.
What Happens Next
The trajectory of bond yields now depends on whether Middle East hostilities escalate or de-escalate. If the Strait of Hormuz remains disrupted and oil holds above $74, the 10-year yield could push toward 5%, a level that would likely trigger further equity rotation out of growth stocks. If tensions ease and Brent pulls back below $70, inflation fears would cool, pulling yields back below 4.5% and giving the Fed room to maintain its current stance.
The Federal Reserve's June meeting minutes, due Wednesday, will offer the first glimpse of how Chair Kevin Warsh and his colleagues assess the oil-driven inflation risk. Markets will parse the language for any shift in forward guidance after Governor Christopher Waller said Monday that forward guidance can be a "valuable tool" but problematic when used inflexibly.
