• U.S. Treasury Secretary Scott Bessent reiterates that the recent surge in bond yields is unusually tied to energy prices, pointing to oil's spike above $100 per barrel.
  • The 10-year Treasury yield briefly topped 5%, a level not seen since 2007, as Middle East supply disruptions roil markets.
  • Bessent acknowledges other drivers, including deficits and Treasury supply, but stresses energy as the key accelerant.

Bessent Doubles Down on Energy-Bond Link

U.S. Treasury Secretary Scott Bessent on Wednesday repeated his argument that the recent climb in government-bond yields is unusually correlated with energy prices, as renewed Middle East supply fears pushed Brent crude above $100 per barrel and the 10-year Treasury yield briefly breached 5% for the first time since 2007.

Speaking at a House Financial Services Committee hearing, Bessent characterized the move as stemming from “global issues,” while also acknowledging that the federal deficit affects the 10-year yield. His comments came after oil loadings at Saudi Arabia’s Yanbu Red Sea terminal were suspended and the country’s East-West pipeline was closed following a Houthi attack. Traders warned that a prolonged disruption could remove as much as 4% of global supply.

“What we’re seeing is an energy shock that is feeding directly into inflation expectations and, consequently, into long-end yields,” Bessent said, according to people familiar with the matter. He added that while deficits and Treasury supply are material drivers, the recent acceleration is “unusually correlated” with energy.

The Transmission Mechanism

The relationship between oil and bond yields is straightforward: higher energy costs raise overall inflation, which can force the Federal Reserve to keep rates higher for longer, and investors demand greater compensation for holding long-dated debt. That dynamic has been on full display in recent weeks, with the 10-year yield rising to roughly 5.02% intraday on September 15, the highest since mid-2007.

Bessent defended Treasury’s recent purchase of longer-dated bonds, asserting that the buyback supported market liquidity and prevented yields from rising even further. The operation totaled $5.187 billion in 10- and 20-year securities, but analysts viewed the scale as small against the approximately $32 trillion Treasury market.

“It’s a drop in the bucket,” said one fixed-income strategist, who requested anonymity to speak freely. “The market is pricing in a structural shift, not just a temporary oil spike.”

Still, Bessent’s argument has some support. Reuters’ market analysis called energy the largest aggravating factor in the previous two weeks, while also emphasizing that the long-end move reflected a broader reassessment of future real interest rates, economic growth, and major investment demands such as AI infrastructure.

Market and Economic Fallout

The yield surge has immediate consequences. The average 30-year fixed mortgage rate has exceeded 7%, while gasoline averages $4.32 per gallon and diesel $6.23 per gallon, pressuring household budgets. Major U.S. stock indexes fell as oil and yields rose, with technology shares hit hardest due to higher discount rates.

Higher yields also increase the government’s interest expense, diverting resources from other programs. The national debt recently exceeded $40 trillion, according to Reuters, making the sensitivity of bond yields to inflation shocks more consequential.

At the hearing, Bessent faced questions not only about bond yields but also about the administration’s punitive financial measures against Iran. Protesters briefly interrupted the proceedings, calling for an end to the war and sanctions on Iran. Bessent also said he would meet Chinese Vice Premier He Lifeng ahead of a Trump-Xi meeting, with Iran and China’s financial ties to Tehran expected on the agenda.

Political Pressure Mounts

Democrats argued that Treasury interventions had not stopped the selloff and challenged Bessent over the consumer effects of higher energy and borrowing costs. Republicans emphasized broader economic resilience and Bessent’s defense of the administration’s policy agenda.

Bessent also defended coordinated U.S.-Japan foreign-exchange intervention designed to support the yen, arguing a stronger yen would help U.S. exports and reduce the need for Japan to sell U.S. assets to finance currency intervention.

The 5% threshold matters partly because Treasury yields had not been at those levels since 2007, just before the global financial crisis. But today’s catalyst is primarily an inflationary energy shock combined with fiscal and supply-demand pressures, rather than a housing-credit-system collapse.

What to Watch

In the near term, the key variables are whether oil supply disruptions worsen, whether the Fed signals further tightening, and whether long-dated Treasury auctions remain well subscribed. Bessent argues the buybacks have helped, citing strong subsequent auctions, but analysts questioned whether a roughly $5–6 billion action can materially control yields in a market measured in tens of trillions of dollars.

If oil remains high, the economy could experience a “higher-for-longer” rate environment, hurting borrowers while benefiting some savers. Conversely, a credible reduction in geopolitical energy risk could bring yields down. But even if energy pressure recedes, long yields may remain elevated if markets conclude that the economy’s neutral interest rate has risen due to resilient growth and sustained capital-investment demand, including AI and data-center buildout.

A Treasury spokesperson did not immediately respond to a request for comment.
