Trump Administration vs. the Bond Market: Its Push for Lower Yields Backfires

 

Treasury Rates are directly impacting Mortgage Rates. The Benchmark 10 year US Treasury is now at the highest since before the Financial Crisis. 

Treasury Secretary Scott Bessent has spent much of his tenure trying to talk, buy and manage the 10-year Treasury yield lower. As of September 25, 2026, the bond market is winning: the 10-year sits near 5.19%, close to its highest level since 2007, and the 30-year is around 5.5%.

That is almost a full percentage point above where the 10-year stood a year ago. The gap between Bessent’s target and the market’s verdict now shapes everything from federal interest costs to the rate on a 30-year mortgage.

Bessent has been explicit that the 10-year, not the Fed’s overnight rate, is the number he cares about. It sets the tone for mortgages, auto loans and corporate borrowing. His bet was that fiscal discipline, cheaper energy and clever debt management could pull it down. The past two months have tested that bet hard.

He used several tools in an attempt to achieve it, from trying to borrow short term vs issuing longer term bonds to buying back its own bonds. 

On August 19, 2026, he said the US Treasury would at least double its long-end buybacks, from $2 billion to at least $4 billion per operation in the 10-to-30-year sectors. A day later Bessent told CNBC that the Treasury would “make a market” in long bonds and that operations could exceed $4 billion. Reports followed that Treasury could draw on its roughly $1 trillion cash balance to fund them (essentially using the checkbook of the treasury to fund long term investments).

Bessent has also backed easing bank capital requirements so banks can hold more Treasurys

How the market reacted

The market gave Bessent one good day, then went back to pricing fundamentals. The August 19 buyback announcement knocked the 10-year down about 6 basis points, but yields were climbing again within 24 hours and broke above 5% in September.

Why it didn’t stick. The forces pushing yields up are larger than anything Treasury can buy. National debt passed $40 trillion in August, inflation is running above the Fed’s target, the Iran conflict has kept oil high, and tech companies are issuing record corporate debt to fund AI build-outs. Even doubled, the buybacks are small against that supply.

The Bond market saw through Bessent’s attempt to force the bond market to lower rate. And then the Treasury overrode its own published schedule just two weeks after releasing it. Some critics went further: the surprise timing chipped at Treasury’s long-standing “regular and predictable” approach to debt management.

Treasury and the Fed are pulling in different directions

Bessent is trying to hold long rates down just as the Fed is pushing short rates up. On September 16 the Fed, under Chair Kevin Warsh, raised its target range 25 basis points to 3.75%–4.00%, its first hike since July 2023, in a 12–0 vote. Most officials expect one more hike this year.

Warsh, who took over in May, has framed inflation as the Fed’s problem to fix and has argued against using the Fed’s balance sheet to suppress yields. That rules out the most powerful tool for lowering long rates, quantitative easing. Bessent, by contrast, has described recent inflation as a temporary supply shock from oil and tariffs.

The tension cuts both ways.  Suppressing yields could make the Fed’s inflation fight harder, and called Bessent’s motives short-term and election-driven. Supporters counter that Treasury is only restoring liquidity in a thin, dysfunctional long end, which is a core debt-management job.

What it means for borrowers

Mortgage rates have followed the bond market, not the Treasury Secretary. Freddie Mac’s 30-year fixed average hit 7.03% on September 24, 2026, up from 6.95% a week earlier and 6.30% a year ago; the 15-year averaged 6.42%. It was the fifth straight weekly increase and the first reading above 7% since January 2025.

The swing within 2026 is sharp. The 30-year hit its low for the year, 5.98%, on February 26. On a $500,000 loan, moving from 5.98% to 7.22% adds about $410 a month in principal and interest. The MBA’s measure reached 7.12% in the week ended September 18, and the adjustable-rate share of applications rose to 9.8% as borrowers looked for lower starting rates.

Economists are split on where rates go next. NAR’s Lawrence Yun has said to expect 7% as the new normal, while also noting a deal ending the Iran war could pull oil and mortgage rates down quickly. For now, Bessent’s buybacks have not moved the one number most households feel.

One thing seems clear at least: when the US government strong-arms the bond market, the latter wins invariably. And the mortgage markets loses.
