US 10-Year Treasury Yield Surges to Highest Level Since 2007

The yield on the U.S. 10-year Treasury note climbed to 5.223%, its highest level since June 2007, CNBC reported on Sept 26, 2026, as traders increased bets that the Federal Reserve will raise interest rates again in October.¹

Yields climb across the curve

According to CNBC, the 10-year yield had been trading just below 4.8% earlier in the month before surging to 5.223% by Sept 26, while the 30-year Treasury note reached 5.501%, its highest level since June 2004, and the 2-year note rose to 4.941%.¹

The Hill said the 10-year yield closed at 5.11% on Wednesday, up roughly 14 basis points, after peaking above 5.13% during the session — the highest close since July 2007.³

By Sept 27, aol.com characterized Treasury yields as the highest in two decades, putting the 10-year note at 5.10% and the 30-year at 5.44% — figures that diverge slightly from CNBC's 5.223% reading for the 10-year note, underscoring inconsistencies in reported levels across outlets.⁵¹

Fed policy and inflation expectations

The CME FedWatch tool showed a 64% likelihood of a Federal Reserve rate increase in October, according to CNBC, while the same outlet reported that traders had at one point priced in a more-than-75% chance of an October hike, up from roughly 49% a week earlier, with markets pricing in four hikes through next year.¹

University of Michigan data showed year-ahead inflation expectations rising to 4.6% in September from 4% in August, the highest reading since June, CNBC reported.¹

Federal Reserve Board member Michael Barr said, "Further policy adjustments are likely to come to bring inflation down to target," while New York Fed President John Williams said, "It would be reasonable to expect another Fed interest rate hike by the end of the year."¹

Mike Sanders, who leads fixed income at Madison Investments, said, "The recent rise in yields can no longer be attributed simply to concerns over the deficit," adding that "with markets pricing in four rate hikes through next year, the Fed is being pushed toward tighter policy at a time when the risk of a policy mistake is rising."¹

War, oil and government debt

According to The Hill, the 10-year bond yield has climbed consistently since the outbreak of a war involving Iran, with the outlet noting that the yield stood at 3.96% at the close of trading on Feb 27, one day prior to the U.S. and Israel launching the conflict. CNBC separately reported that the war began around Sept 25, contributing to elevated oil prices and rising bond yields.³¹

The Iranian military struck an oil tanker in the Strait of Hormuz, The Hill reported, while Adm. Brad Cooper, head of U.S. Central Command, said U.S. forces had helped facilitate the movement of over 1 billion barrels of crude through the strait over recent months. West Texas Intermediate crude closed at $92.16 a barrel after surpassing $100 the previous week.³

The U.S. national debt passed $40 trillion in August, The Hill reported, and bond yields also rose in the United Kingdom, Germany and Japan, where the 10-year government bond yield reached its highest level since August 1996, according to CNBC.³¹

Effect on borrowing costs

Dominic J. Pappalardo, who serves as chief multi-asset strategist at Morningstar Wealth, said, "As the 10-year yield goes up, borrowing costs for mortgages also go up almost in lockstep with it," adding that "things like auto loans are also impacted. In general, most types of consumer financing or borrowing rates are quite closely tied to the 10-year Treasury yield."¹

Pappalardo said the shift also benefits savers: "Higher interest rates benefit savers and investors just as much as they're harming spenders," and "if you have money in savings or money to invest as interest rates go up, you are being paid a higher interest rate or generating more income from your savings and investments because of the yields moving up."¹

CNBC reported that heavy corporate debt issuance has contributed to the rise in yields. According to Vanguard estimates, five major tech firms — Alphabet, Amazon, Meta Platforms, Microsoft and Oracle — had collectively issued roughly $132 billion in debt by July, far exceeding the approximately $35 billion annual average seen from 2020 to 2024, with total AI-related debt issuance this year potentially climbing to between $300 billion and $570 billion.¹

Where investors are looking

Steve Laipply, who co-heads iShares Fixed Income ETFs globally at BlackRock, said, "There's potentially a really strong opportunity to lock in very attractive levels. We call this a once-in-a-generation income opportunity," adding that cautious investors "could buy something like SGOV," the iShares 0-3 Month Treasury Bond ETF, which CNBC reported holds $111 billion in assets and carries a 30-day yield of 3.67%.¹

aol.com pointed to income vehicles including Ares Capital, a business development company with a $13.8 billion market capitalization, a roughly 600-company portfolio and a 10.2% forward dividend yield, and Main Street Capital, which pays a 6.1% base monthly yield with a total annual yield regularly exceeding 9% through special dividends. It also cited the Vanguard Federal Money Market Fund's 3.7% seven-day yield and the Invesco BulletShares 2028 Corporate Bond ETF's 5.7% locked-in yield, while noting the iShares iBoxx Investment Grade Corporate Bond ETF has declined 6.31% year-to-date because of its 8.3-year portfolio duration.⁵

Pappalardo cautioned that price swings from further rate moves would likely be limited: "Even if rates go from 5% to 6%, yeah, you may see some price decline, but it's relatively marginal," and said investors should adjust rather than overhaul their holdings: "I wouldn't suggest somebody completely rebuilds their entire portfolio or investment approach today," though "it's prudent and makes sense to tweak it to try and take advantage of that new marginal opportunity to generate more income off of bond investments."¹

Market mood

Robin Brooks of the Brookings Institute described one recent trading session as the "worst day in global bond markets in quite some time," The Hill reported.³

The New York Times noted, without giving further detail, that markets and the economy have previously flourished at times when interest rates were higher than current levels, though it added that those periods of higher rates and flourishing markets did not last.²
