The yield on the benchmark 10-year U.S. Treasury note climbed above 5% on Tuesday, reaching its highest level since July 2007 as a global bond selloff intensified, driven by elevated energy prices, renewed inflation risks, expectations for tighter Federal Reserve policy and heavy corporate borrowing linked to artificial-intelligence investment.
The move above 5% marks a significant threshold for global financial markets. Higher Treasury yields can raise borrowing costs across mortgages, corporate debt and other forms of credit while increasing the relative attractiveness of government bonds compared with equities.
The benchmark yield had already crossed 5% on Monday before extending higher Tuesday. The selloff has spread across global sovereign-debt markets, with yields in Europe and Japan also under upward pressure.
Oil Prices Add to Inflation Pressure
Energy markets remain a major source of pressure on bonds.
Oil prices extended gains Tuesday as Saudi Arabia’s East-West Pipeline remained shut following an attack on the strategically important route. The pipeline has recently transported roughly 4 million to 5 million barrels of crude per day toward the Red Sea, providing an alternative export route while shipments through the Strait of Hormuz remain constrained.
Brent crude was trading above $105 a barrel Tuesday, while West Texas Intermediate remained above $102, keeping concerns about energy-driven inflation elevated ahead of the Federal Reserve’s policy decision.
The pressure on global fuel supplies has also been compounded by disruptions to Russian refining capacity. Half of Russia’s six largest diesel-producing refineries have significantly reduced or halted production this month following drone attacks, according to Reuters calculations.
Russia-Ukraine Energy Truce Remains Uncertain
Energy markets are also following developments surrounding attacks on Russian and Ukrainian infrastructure.
President Donald Trump said Russia and Ukraine had agreed to stop attacking each other’s energy facilities. Ukraine, however, has not confirmed that a final agreement is in place, with President Volodymyr Zelenskiy saying Kyiv is prepared to participate in an arrangement provided there are credible guarantees that Russia will also stop attacks on Ukrainian energy and other critical infrastructure.
Attacks continued Tuesday despite the proposed arrangement, with Russia and Ukraine reporting strikes against energy-related targets.
The uncertainty is significant for global energy markets because damage to Russian refining infrastructure has contributed to tighter diesel supplies at the same time that Middle East disruptions are constraining crude flows.
Fed Rate Hike in Focus
Treasury markets are also preparing for Wednesday’s Federal Reserve decision.
Interest-rate futures were pricing approximately a 92.5% probability of a 25-basis-point increase, according to Reuters on Tuesday. Such a move would represent the Fed’s first rate increase since July 2023.
The focus will extend beyond the immediate decision to the central bank’s projections and indications of whether policymakers see additional tightening as necessary.
Recent increases in oil and other energy costs have complicated the inflation outlook, reinforcing concerns that price pressures could remain above the Fed’s objective and require interest rates to stay elevated for longer.
AI Investment Adds Pressure to Bond Markets
Another force behind rising long-term yields is coming from the technology sector itself.
Companies financing large-scale artificial-intelligence infrastructure have increased corporate debt issuance, adding to the supply of bonds competing for investor capital. Reuters cited heavy corporate borrowing associated with AI investment as one of the factors contributing to the rise in Treasury yields alongside inflation and fiscal concerns.
The effect is particularly relevant because AI infrastructure requires enormous amounts of capital for data centers, semiconductor equipment, power generation and computing capacity.
Heavy corporate issuance can absorb balance-sheet capacity among primary dealers and other financial institutions, while forcing government debt to compete with a growing supply of corporate securities for investor demand.
That dynamic comes as concerns over the U.S. fiscal outlook and the volume of Treasury issuance are already placing pressure on longer-term borrowing costs.
Technology Stocks Face Higher-Yield Pressure
The rise in Treasury yields is also adding another challenge for technology stocks following Monday’s selloff linked to the debate over slowing frontier AI development.
U.S. equity futures moved lower Tuesday, with Microsoft and Alphabet down around 1% in premarket trading, as investors weighed higher oil prices, Treasury yields above 5% and uncertainty surrounding the future pace of AI investment.
Higher long-term rates can weigh particularly heavily on growth stocks because a larger portion of their valuations depends on expected earnings further into the future.
The combination of Treasury yields above 5%, elevated energy prices and expectations for tighter monetary policy therefore puts several of the forces that have shaped markets this year into the same equation: inflation, government borrowing, AI investment and interest rates.
