Global Bonds Extend Selloff as Oil Prices Surge on Renewed US-Iran Strikes

Market Reactions to Renewed Geopolitical Tensions and Inflation Fears

By Caroline Valetkevitch and Harry Robertson

Bond Yields Surge Globally

NEW YORK/LONDON, Sept 1 (Reuters) - Global bond yields rose on Tuesday, extending a broad-market selloff in government debt fed by inflation fears, while oil prices surged to five-week highs after a new round of U.S. strikes against Iran refocused attention on the simmering Middle Eastern conflict.

The yield on the benchmark U.S. 10-year Treasury note rose 3.4 basis points to 4.792% after at one point touching 4.798%, highest since January 2025. The 10-year yield has risen for five straight sessions, its longest run since March.

Earlier, Japan's 10-year benchmark yield hit 3% for the first time since 1996, while British and euro zone yields hit over-10-year highs. Yields move inversely to prices.

Expectations for Interest Rate Hikes

Expectations for interest rate hikes also have risen.

"The global bond selloff is putting worldwide central banks on notice," said Jake Dollarhide, chief executive officer of Longbow Asset Management in Tulsa, Oklahoma.

"Potentially, it's rate hikes across the board. That's not good for any company including tech," he said. Higher rates increase borrowing costs for businesses as well as consumers.

Oil Prices Hit Five-Week Highs

Higher oil prices are contributing to the inflation worries. New air strikes on Iranian targets fanned worries of a wider renewal of hostilities in the six-month conflict. Since joint U.S.-Israeli strikes on Iran at the end of February, the world's energy reserves have run down due to the closure of the crucial Strait of Hormuz, putting upward pressure on fuel prices.

Oil settled at five-week highs. Brent futures rose $4.16, or 4.6%, to $94.65 a barrel. U.S. West Texas Intermediate (WTI) crude rose $4.46, or 5.2%, to $90.22. That was the highest close for Brent since July 24 and the highest for U.S. crude since July 23.

Central Banks and Inflation Outlook

Euro Zone and U.S. Federal Reserve Policy

Euro zone inflation rose back above 3% in August due to higher energy costs, bolstering the case for a September rate hike from the European Central Bank.

Investors are also increasingly of a mind that the U.S. Federal Reserve could raise rates at its meeting in two weeks. Chair Kevin Warsh gave a hawkish speech last week on the inflation outlook that was followed up by Fed Governor Michael Barr on Tuesday, who said if inflation does not cool quickly, it will be time for the Fed to raise rates.

Rate Hike Probabilities

Expectations for a hike of at least 25 basis points from the Fed at its September 15 to 16 meeting stand at 66.2%, according to CME Group's FedWatch Tool, up from 39.6% a week ago.

Stock Markets and Currency Movements

Wall Street and Global Equities

Wall Street's major stock indexes fell and a global equity index was down as well.

The Dow Jones Industrial Average fell 419.02 points, or 0.8%, to 52,766.88, the S&P 500 fell 54.67 points, or 0.7%, to 7,631.47 and the Nasdaq Composite fell 271.11 points, or 1%, to 26,099.77.

Seasonal Trends in Equities

Seasonal weakness could be weighing on investor sentiment. September is the only month with a negative average return since 1926, according to Fisher Investments, which cited data from Finaeon.

MSCI's gauge of stocks across the globe fell 6.49 points, or 0.56%, to 1,142.73. The pan-European STOXX 600 index fell 0.56%.

Currency Markets and the U.S. Dollar

The dollar strengthened against major currencies. Higher yields drive investors to buy safe-haven currencies like the U.S. dollar.

The dollar index, which measures the greenback against a basket of currencies including the yen and the euro, rose 0.27% to 99.68, with the euro down 0.23% at $1.1589. The Japanese yen fell 0.3% to 160.19 per dollar.

Upcoming Economic Data and Commodities

Key U.S. Economic Reports

U.S. August jobs and consumer price inflation data, which are both due before the Fed's next meeting, may now be key to whether the U.S. central bank hikes next month.

This Friday's jobs report is expected to show that employers added 56,000 jobs last month, according to the median estimate of economists polled by Reuters.

Gold Prices Under Pressure

Gold dropped to a two-week low amid the elevated Treasury yields and stronger U.S. dollar. Spot gold fell 2.69% to $4,328.60 an ounce.
