A twist of $4bn against a debt of $40tn
The Treasury can change who holds the duration, but not how much borrowing there is, and the market spent three sessions demonstrating the difference.
Scott Bessent described last week's intervention as "what I would call a Treasury twist": buy back long-dated bonds, and fund the purchases by issuing more short-dated bills. The Treasury will at least double liquidity-support buybacks in the 10-to-20 and 20-to-30 year buckets from $2bn to at least $4bn per operation, running 9 September to 4 November. Two things about that. First, the size. An eight-week programme of $4bn operations is tens of billions of dollars. One gauge of the federal debt passed $40tn this month. The 30-year auction that preceded all this was $25bn on its own, and cleared at 5.216%, the highest for that tenor since 2001. As a demand offset, this is not large; as a signal, it was large enough to move gold about 5% in a week. Second, the mechanism. Buying long bonds with bill proceeds shortens the average maturity of the federal debt. It reduces the amount of duration the market has to hold, which is the point, and increases the frequency with which the government has to refinance, which is the cost. The buyer of the extra bills is money funds and — via repo — the leveraged Treasury complex the OFR sized at roughly $2tn of hedge-fund cash Treasuries funded overnight. Bessent's own preferred benchmark closed the week at 4.73%, near the highest since he took office. "Every route to lasting relief for the long end runs through something the administration doesn't want," Satori Insights' Matt King told Bloomberg: a smaller deficit, a falling stock market, or less AI investment.
