Dow, S&P 500, and Nasdaq open lower as bond market shrugs off Bessent’s buyback boost
Treasury Secretary doubled the size of liquidity-support buybacks to $4 billion per operation, but the bond market's reaction lasted roughly one trading session.
US stock markets opened lower on August 20 as a brief reprieve in the bond market evaporated overnight, dragging equity indices back into the red. The Dow Jones Industrial Average, S&P 500, and Nasdaq all declined at the open, reversing gains from the previous session that had been fueled by Treasury Secretary Scott Bessent’s announcement of expanded buyback operations.
What happened with the buybacks
On August 19, the Treasury Department announced it would at least double the size of its liquidity-support buyback operations for longer-dated nominal coupon securities. The cap on each operation rises from $2 billion to a minimum of $4 billion, effective from September 9 through November 4, 2026.
Bessent framed the move as providing “greater liquidity support” in longer-dated sectors of the Treasury market. The initial market reaction was exactly what you’d want if you were the Treasury Secretary: the 30-year yield dropped over 10 basis points to around 5.184%, pulling back from a 19-year high above 5.33%.
Stocks responded in kind on August 19. The S&P 500 closed up 0.21% at 7,707.98, while the Dow added 119.65 points.
By the morning of August 20, Treasury yields had begun climbing again, putting renewed pressure on equities.

Why $4 billion barely registers
US public debt outstanding has now surpassed $40 trillion. Against that backdrop, a buyback operation capped at $4 billion per round is roughly 0.01% of the total outstanding debt.
The buyback program is designed to improve liquidity, not to fundamentally alter supply and demand dynamics in the Treasury market. It targets off-the-run securities, which are older, less frequently traded bonds, and replaces them with newer, more liquid ones.
What to watch from here
The expanded buyback operations don’t begin until September 9, which means the market has nearly three weeks to digest the announcement before any actual purchases occur. The November 4 end date for the expanded program gives the Treasury a defined window of enhanced intervention, after which operations would presumably revert to the previous $2 billion cap unless extended.
