Treasury Could Tap Its $1tn General Account to Fund Bond Buybacks

The Treasury could use its nearly $1tn General Account to help fund its expanded purchases of government bonds, according to two senior Treasury officials.

That would give the department considerable firepower to influence long-term yields.

The gap markets had filled in themselves

Treasury surprised markets by announcing it would double buybacks of off-the-run long-end securities from $2bn to at least $4bn, with Bessent saying on CNBC the operations could be larger still. It said nothing about how they would be funded.

Most participants assumed short-term bill sales. The officials did not rule that out, and Bessent's own description — a "Treasury Twist," echoing operations where long-dated debt is bought and paid for with short-term issuance — pointed the same way.

Why the funding source changes the trade

The two mechanisms are not equivalent, which is why the detail matters.

Funding buybacks with bill issuance is a swap: long-dated debt comes out of the market, short-dated debt goes in. The net supply is unchanged and the effect works through duration.

Drawing on the TGA is different. That is existing cash leaving the government's account and entering the market, adding liquidity rather than shifting its composition — closer in effect to easing than to a maturity swap, and executed by Treasury rather than the Fed.

Since the surprise announcement, bonds have given back their initial rally, which suggests the market has been working through exactly this question.
