Scott Bessent’s Treasury Twist prompts Wall Street to rethink borrowing strategy

Treasury Secretary Scott Bessent is pulling a page from the Federal Reserve’s old playbook, and Wall Street is scrambling to figure out what it means for borrowing costs.

Bessent announced on August 19-20 that the Treasury will dramatically expand its bond buyback program starting September 9, 2026, purchasing at least $4 billion of longer-dated Treasuries, those maturing in 10 to 30 years, in each operation. The catch: all of it funded by cranking up issuance of shorter-term Treasury bills.

Operation Twist, Treasury edition

Bessent is calling it a “Treasury twist,” and the name is no accident. The original Operation Twist was a Fed maneuver from the early 1960s, later revived after the 2008 financial crisis, where the central bank sold short-term bonds and bought long-term ones to push down borrowing costs without printing new money. Bessent’s version swaps the actor but keeps the basic mechanics: soak up long-dated supply to compress yields on the far end of the curve while letting short-term rates absorb the pressure.

The context matters. US public debt has ballooned to $40 trillion, and long-term yields have been climbing to levels not seen in nearly two decades. The 30-year Treasury yield recently touched a 19-year high, making it painfully expensive for the government to finance itself at the long end. Bessent, a former hedge fund manager confirmed by the Senate in January 2025 on a 68-29 vote, argued in an August 20 interview that current yields “do not reflect underlying fundamentals.”

The market’s mixed verdict

Wall Street’s initial reaction was encouraging for Bessent’s thesis. Thirty-year yields dropped by about 10 basis points immediately following the announcement, a meaningful move in the bond world where a single basis point shift on trillions of dollars of debt translates to enormous sums.

But the relief was short-lived. Yields bounced back, with the 10-year benchmark closing around 4.73%. Analysts believe the buybacks will have limited impact due to ongoing significant issuance and persistent factors exerting upward pressure on yields, namely persistent fiscal deficits and inflation running near 3.7%.

The dynamic creates an interesting tension with the Federal Reserve’s monetary policy under Chair Kevin Warsh. The Fed controls the short end of the yield curve through its policy rate, while Bessent is now actively trying to manage the long end through supply manipulation.

What it means for corporate borrowers

The ripple effects extend well beyond government bond traders. Corporate bond rates are priced as a spread above comparable Treasuries, so if Bessent’s twist successfully suppresses 10- and 30-year yields even modestly, it could shave meaningful basis points off corporate borrowing costs for companies looking to issue long-dated debt.

For the broader fixed-income ecosystem, the shift in Treasury issuance composition introduces new dynamics. Money market funds and short-duration investors will see a larger pool of bills to absorb, while pension funds and insurers that depend on long-dated Treasuries for liability matching may find supply tightening in their preferred maturities.
