Treasury’s $1 Trillion Cash Reserve Could Become a New Bond-Market Lever
The Treasury is considering turning its nearly $1 trillion cash reserve into a powerful tool for reshaping the bond market—potentially easing long-term borrowing costs while raising fresh questions about how far the government should intervene.

The possibility, reported after conversations with two senior Treasury officials, pushed Treasury yields lower. The 10-year yield fell more than three basis points, while the 30-year yield dropped more than four basis points after recently reaching its highest level since 2007.

The proposed funding source is the Treasury General Account, effectively the government’s checking account at the Federal Reserve. Treasury Secretary Scott Bessent has expanded it to roughly $950 billion, well above the $550 billion to $600 billion range associated with the previous administration. Using even part of that balance could give the department more firepower than investors initially expected when it doubled planned purchases of older, less-traded long-term bonds from $2 billion to at least $4 billion.

That prospect contrasts with the market’s original assumption that Treasury would finance the purchases by issuing more short-term bills—a strategy Bessent has described as a “Treasury Twist.” Drawing from the account could reduce concern that the Federal Reserve might be pressed into supporting the operation, but it would also leave the government with a smaller cash cushion ahead of a possible debt-ceiling confrontation.

Treasury officials reject criticism that the buyback announcement abandoned the department’s tradition of being “regular and predictable,” arguing that auction schedules remain unchanged and that markets had nearly three weeks to prepare. Critics, however, see a policy with uncertain effectiveness and potentially significant signaling power: even the prospect of using the account may move yields.

The intervention also makes Federal Reserve Chair Kevin Warsh’s upcoming Jackson Hole speech more consequential. As investor Richard Reyle put it, “Interest rates may be the single most important thing in our economy right now.”
