The 30-Year Treasury Yield Crowds Out Mortgages and Hollywood

The U.S. 30-year Treasury yield traded as high as 5.62% on September 29, the most since June 2002. The official par curve closed at 5.59%.

Home loans, the federal interest bill, and a $52 billion studio takeover are now priced off that level, even as the 2-year yield fell the same day.

A 24-Year High on the Long Bond

The long bond rose for a sixth straight session, a move that pushed it back into a range last printed in June 2002, before the long stretch of cheap money that followed the financial crisis and the pandemic. The par close of 5.59% was up 3 basis points on the day, 37 basis points above 5.22% a month earlier, and 88 basis points above 4.71% a year earlier.

The 10-year, the benchmark that sets the tone for mortgages and a large share of corporate borrowing, closed at 5.26% on the same curve and traded as high as 5.29%, its highest since 2007. The 20-year finished at 5.64%. Only the 2-year, at 4.89%, stayed under 5% among the main coupons.

Marketable Treasury debt stands at about $32 trillion, and secondary trading in those securities averages about $1 trillion a day, Deputy Secretary Francis Brooke told the Treasury Market Conference on September 22. Bond prices in that market are down 2.6% this year after a 6.3% gain last year.

TREASURY PAR YIELDS ON SEPTEMBER 29

The curve still slopes up. The 10-year sits 37 basis points over the 2-year. That is not an inversion story. It is a long-end story, and the long end is where households, Hollywood, and the Treasury itself all borrow.

The Short End Did Not Confirm the Move

A Fed scare would have lifted the 2-year with the 30-year. It did the opposite on September 29. The 2-year dropped 3 basis points while the long bond made a 24-year high, which is the signature of extra term premium, the added yield investors demand to hold Washington’s paper for decades, not a fresh bet on overnight policy.

The Federal Reserve raised its target range to 3.75% to 4.00% on September 16, the first increase since 2023. CME FedWatch put the chance of another 25-basis-point move at the October 27-28 meeting at 68.1% on September 28. That figure had already swung around after the September meeting, and it is a poor match for a 30-year that kept selling even when oil did not.

Brent crude settled at $102.59 a barrel on September 29, down 2.6%. West Texas Intermediate settled at $89.38, down 3.5%. Energy still feeds inflation after a war with Iran that began in late February, and August CPI ran at 3.4% year over year with gasoline up 3.9% that month. The Fed’s own 2026 PCE projection sits at 3.7%. But a session in which crude fell and the 2-year fell while the 30-year made a two-decade high is not an oil-only tape.

Mohamed A. El-Erian, the Allianz adviser and former PIMCO chief executive, put the curve on a single screen: with the exception of the 2-year, every maturity was above 5%.

Citigroup strategists have called the backing-up a light buyer’s strike. JoAnne Bianco, senior investment strategist at BondBloxx Investment Management, said investors want more term premium because of inflation, U.S. fiscal deficits, and the amount of Treasury supply. Hardika Singh, economic strategist at Fundstrat, said valuations start compressing after 5.5%, and that investors, companies, and consumers then have to redo the math on what they own.

The 10-year is already through that 5.5% line on the official curve. The redo is not a forecast.

Homebuyers Are Already Paying 7.03%

Mortgage rates do not wait for the next FOMC statement. They track the 10-year, plus a spread for prepayment risk and the cost of packaging the loans, and the weekly survey that most of the country still cites has already broken 7%.

Freddie Mac said the 30-year fixed-rate mortgage averaged 7.03% as of September 24, up from 6.95% the prior week and from 6.30% a year earlier. The 15-year averaged 6.42%, up from 6.26% and from 5.49% a year earlier. That 7.03% print is the highest since January 16, 2025, when the same survey stood at 7.04%.

WHAT THE NEW MORTGAGE MATH LOOKS LIKE

• Weekly average: Freddie Mac’s 30-year fixed rate is 7.03% for the week ended September 24, the fifth straight weekly rise in that series.
• A $400,000 loan: Principal and interest come to about $2,670 a month at 7.03%, against about $2,476 at last year’s 6.30%, a gap of $194 a month before taxes and insurance.
• Purchase notes: The American Enterprise Institute’s housing indicators put the median purchase note rate of 6.99% in week 39, while Mortgage News Daily’s daily quote was 7.50% on September 28.

Those daily quotes sit above the Freddie average because they sample a different window, after the 10-year had already lurching toward 5.2%. They are not a replacement for the survey. They show where a borrower who locked after September 24 was shopping.

August house-price growth was still running at 1.3% year over year on AEI’s preliminary reading, and wages have been growing faster than prices, which is why some affordability indexes have inched up even as the rate does the opposite. The payment still jumped. A buyer who waited a year for a cheaper loan is paying $194 more each month on a $400,000 balance, or about $2,328 a year, before a single extra dollar of principal.

Selma Hepp, chief economist at Cotality, has sketched a worse case in which the 10-year goes to 6% or 7% and mortgages, with a two-point spread, print 8% or 9%. On a $400,000 loan, she said, a move from 7% to 8% adds a little under $300 a month. Mark Zandi has argued the rate should drift back toward 6% by 2027 or 2028 if inflation settles. Neither path is in the Freddie number. The 7.03% is.

Why Bessent’s Buybacks Have Not Capped Yields

Treasury Secretary Scott Bessent expanded long-end buybacks in mid-August, when the 30-year was near 5.2%, and later lifted operation caps toward $6 billion. The 30-year still closed at 5.59% on September 29, 39 basis points higher than that mid-August handle. The tool is real. The cap is not holding.

Brooke said the department has nearly $500 billion of Treasury buybacks across more than 150 operations, with about $300 billion of that in securities under two years. Liquidity-support operations in the long coupons have been enlarged because that is where dealers want to sell. On September 24 the long-end operation bought $4.08 billion against a $6 billion cap, with dealers offering $10.47 billion. The next dated long-end operation is October 1 in the 10-year to 20-year bucket, at least $4.0 billion.

Buybacks do not shrink the debt. They swap one coupon for another, often funded by bills. Net bill supply rose more than $550 billion in July and August, about 8% in two months, and money-market funds took about 85% of that extra paper, Brooke said. Banks have added more than $300 billion of Treasurys since the end of 2024. Stablecoin issuers hold nearly $200 billion of bills and other short coupons. The Fed itself has bought more than $300 billion of bills this year. Demand at the front end is not the shortage.

The shortage is a patient buyer for 20-year and 30-year paper while issuance stays heavy and the war keeps inflation above target. August nonfarm payrolls rose by 162,000 and unemployment held at 4.1%, so the growth case for higher term premium has not broken either.

THE INTEREST BILL ALREADY ON THE BOOKS

• Gross interest: The Monthly Treasury Statement records $1.267 trillion of interest expense on the public debt through August of fiscal 2026, already above the $1.220 trillion paid in all of fiscal 2025.
• Net interest: The same statement puts net interest at $1.017 trillion year to date, ahead of $876 billion for national defense.
• The stock of debt: Total public debt was $40.069 trillion on September 24. Debt held by the public was about $32.4 trillion at the end of August.

Every extra tenth of a percent on new long bonds is a coupon the next refunding has to pay for 30 years. That is the channel from a 5.59% par close to the budget, and it does not require another hike to keep running.

Paramount Skydance Competes With the Treasury

Into that bid, Paramount Skydance brought one of the year’s largest corporate debt packages, a $52 billion stack meant to help pay for its $110 billion purchase of Warner Bros. Discovery. The high-grade slice drew more than $109 billion of orders when books closed on September 29, about 3.6 times the amount expected after the company cut the bond portion by $2 billion, to $30 billion, and shifted that $2 billion into loans.

Price talk on the longest note, due in 2066, was about 3.65 percentage points over Treasurys. The package also includes about $12.4 billion of junk bonds and a $7.5 billion term loan, with lender commitments due September 30. An SEC pro forma for the deal assumes $51.9 billion of new permanent financing, a figure that sits beside the marketed $52 billion package rather than replacing it.

The delay is the expensive part. Lawsuits held the sale, and borrowing in late September instead of three months earlier will cost the combined company extra interest of $250 million to more than $500 million a year, on estimates circulating with the sale. After closing, the merged firm is expected to carry about $80 billion of debt. Chief executive David Ellison has pledged $6 billion a year of cost cuts within three years to service that load.

Orders at 3.6 times cover show there is still a bid for large, secured paper. They also show that the bid now clears at a spread that would have looked punitive when the bridge loans were first lined up. The same accounts that absorb a $30 billion first-lien sale are the accounts Treasury needs for 10-year and 30-year auctions. That is crowding in its plain form: two borrowers, one calendar week, one pool of duration.

October Supply Hits a Crowded Bid

State Street Investment Management strategist Masahiko Loo said October could present another test for Treasurys as issuance increases and competition for capital intensifies. The calendar already has the pieces in place.

THE DATES THAT BUILT THE 5.59% CLOSE

1. Late February 2026: The U.S.-Iran war begins, and energy prices start the inflation shock that is still in the CPI print.
2. Mid-August 2026: Bessent expands long-end buybacks with the 30-year near 5.2%.
3. September 16, 2026: The Fed lifts the funds target to 3.75% to 4.00%, its first hike since 2023.
4. September 24, 2026: Freddie Mac prints 7.03% on the 30-year mortgage, and a long-end buyback takes $4.08 billion against a $6 billion cap.
5. September 29, 2026: The 30-year trades to 5.62% and closes at 5.59% on the par curve; Paramount’s high-grade books close with more than $109 billion of orders.
6. October 1, 2026: Treasury runs another 10-year to 20-year buyback of at least $4.0 billion.
7. October 27-28, 2026: The FOMC meets, with futures on September 28 still treating a 25-basis-point hike as the base case.

Dealer inventories of Treasurys peaked above $550 billion in March after leverage-ratio relief, Brooke said, which helped intermediation. Fast-money accounts have also taken a larger share of the book as some long-term holders looked elsewhere, a shift El-Erian has been flagging as a source of extra yield volatility. A light buyer’s strike in a $32 trillion market does not need a panic. It needs a week when the government, a studio, and a mortgage pipeline all want the same duration.

Are we now in a new regime of protracted elevated rates? Have we already seen the bulk of the spillovers onto other risk factors and the broader economy? For what it’s worth, and for the reasons detailed earlier, my answers would be yes, and no.

Mohamed A. El-Erian, Allianz adviser, on X, September 30, 2026

New buyers can lock a 5.59% 30-year coupon that did not exist in this market a year ago, when the same bond yielded 4.71%. Homebuyers, the Treasury’s own refunding desk, and a studio paying 3.65 points over that curve do not get the same bargain. The spillover El-Erian says is not finished already has a 7.03% mortgage rate, a $1.267 trillion interest line, and a $52 billion Hollywood book attached to it.
