Treasury yields hit multi-decade highs as oil jumps; Fed officials flag more hikes
The 30-year Treasury yield touched about 5.47% and the 10-year about 5.18% Thursday—levels not seen in roughly two decades—while Brent closed near $106.60. New York Fed President John Williams said another rate hike may be appropriate by year-end as diesel stayed near record highs.

Editor’s note: Afternoon close facts follow NBC News (Steve Kopack, Sep 24, updated ~4:13 p.m. ET), including the diesel correction to a $6.51 national average. Intraday highs (30-year ~5.47%, 10-year ~5.18%, oil near $108 overnight) and closes (Brent $106.60, WTI $94.61, equities flat) are as NBC reported; do not invent CME settles beyond that wrap. The Reuters report of a phased U.S.–Iran path out of war is labeled unconfirmed by NBC—treat as a market rumor that briefly reversed oil and stocks, not as a verified diplomatic deal. Williams and Paulson hike comments are from their Thursday speeches as quoted by NBC.
U.S. Treasury yields surged to multi-decade highs on Thursday even as equity indexes closed roughly flat, with oil prices and Federal Reserve speakers reinforcing a market narrative that inflation pressure from the Iran war is not finished and that another rate hike remains on the table.
What the bond market did: NBC News reported the yield on the 30-year U.S. Treasury bond rose as high as about 5.47%—a level not seen in 22 years—while the 10-year yield climbed as high as about 5.18%, its highest since 2007, after posting its biggest one-day rise since April 2025 on Wednesday. Because the 10-year anchors many consumer borrowing rates, the average 30-year fixed mortgage rate jumped to 7.37% on Thursday, its highest since May 2024, NBC said.
Oil and fuel: Overnight, oil jumped again after mediated U.S.–Iran talks at the U.N. General Assembly produced no tangible public progress toward ending the nearly seven-month war, NBC reported. International Brent crude finished up 3.4% at $106.60 a barrel; West Texas Intermediate rose 2.6% to $94.61. Both benchmarks are up more than 65% year to date in NBC’s wrap. The national average price for diesel was $6.51 Thursday—effectively unchanged day over day but up 73% since the Iran war began—after NBC corrected an earlier erroneous $4.51 figure. Regular unleaded averaged $4.48 a gallon, about 50% higher than when U.S. and Israeli strikes on Iran began in late February.
Intraday whipsaw: Stocks sold off early, with the S&P 500 down about 0.5% and the Nasdaq about 0.9% at one point, then reversed after a Reuters report—unconfirmed by NBC—that U.S. and Iranian negotiators were exploring a phased path out of the war that could include reopening the Strait of Hormuz. Much of oil’s overnight gain briefly reversed on that headline before Brent closed higher anyway; both major U.S. equity indexes finished flat. US Brief treats that Reuters item as an unverified market catalyst, not as an established diplomatic breakthrough.
Why yields keep rising: A major driver this week was Wednesday’s S&P Global report that U.S. business activity accelerated in September even as firms’ input costs jumped at the steepest rate in four years on fuel and transport, NBC said—prompting traders to mark up bets on further Fed tightening. Around the world, Japan’s 10-year yield hit its highest since 1996 and Germany’s 10-year bund yield its highest since 2009, underscoring a synchronized sovereign sell-off.
Fed speakers: New York Fed President John Williams said in a London speech Thursday that the central bank still has more work to do on inflation and that it is “likely that another rate hike may be appropriate by the end of the year,” while also calling the U.S. economy “remarkably resilient” amid significant shocks. Philadelphia Fed President Anna Paulson separately said she expects “some modest further tightening may be warranted.” Those comments land on top of already elevated October hike odds that morning market wraps had put near the low-70% range.
Bessent’s buybacks: Treasury Secretary Scott Bessent conducted a second round of longer-dated Treasury buybacks Thursday, purchasing about $4 billion of 20- and 30-year bonds, NBC reported. Yields still rose to session highs around the operation, though Wells Fargo’s Brian Rehling told NBC the mechanics looked smoother than the first round and that long-end yields remain driven by inflation, Fed expectations, and issuance supply—not by a single buyback. Bessent has also defended yen-support intervention aimed at reducing pressure on Japanese sales of U.S. Treasuries; as of Thursday, NBC said the yen had again weakened toward early-September levels.
Who is affected: Households face higher mortgage quotes and still-elevated gasoline and record-range diesel costs that feed into grocery and freight inflation. Rate-sensitive equities and crypto have been swinging with the bond sell-off. Global bond investors are repricing sovereign risk together with the U.S. long end. The White House and Treasury face a credibility test after Bessent’s “I am the house now” warning earlier this month failed to stop the yield climb.
Uncertainty and competing views: Hawkish Fed speakers and hot input-cost data argue for at least one more hike into year-end; resilient growth and midterm politics may still constrain how aggressive the committee becomes. Oil bulls point to Hormuz risk and failed public diplomacy; a confirmed phased ceasefire or shipping reopening would cut the other way. Buyback skeptics say issuance and inflation expectations swamp the Treasury’s operations; the administration still calls the U.S. bond market the world’s best-performing.
What to watch next: Whether Friday and early next week keep the 10-year above 5% and the 30-year near its multi-decade highs; official confirmation or denial of any phased Iran path; diesel and gasoline weekly averages; Fed speak consistency after Williams and Paulson; and whether Bessent expands buybacks or changes issuance. For readers, Thursday’s confirmed story is multi-decade Treasury yield highs, higher closed oil, flat equities after a rumor spike, and two regional Fed presidents openly floating further tightening—not a verified end to the Iran war.
