The size of the debt stays where it was
From September 9 the Treasury will run its liquidity support buybacks in the 10-year to 20-year and 20-year to 30-year sectors at a maximum of at least 4 billion dollars per operation, up from 2 billion dollars, and the larger size holds until November 4, 2026. The stated reason is operational: the department receives a significant volume of high-quality offers in those sectors and wants to provide greater liquidity support there.[1]
It arrives in a week when total federal debt outstanding passed 40 trillion dollars, five months after it crossed 39 trillion dollars, with interest running above 1 trillion dollars a year and payments in the first 10 months of the fiscal year 15 per cent higher than a year earlier. A repurchase retires securities the government has already issued while the same government keeps borrowing, so the stock does not fall because part of it is bought back.[2]
The Fed sets the price of reserves while the Treasury works the long end
At the August refunding the Treasury said it expected to keep nominal coupon auction sizes unchanged, which left the quarter's seasonal financing swing to bill auctions and the cash balance. The buyback decision fits the same design from the other end. Coupon issuance stays where it is, long-dated paper is repurchased, and the cash for the repurchase comes out of the flexible short-dated leg. The mix the private sector holds shifts toward bills while its total claim on the government stays put.[1], [5]
The central bank is doing none of this. Minutes of the July 28-29 meeting show the Committee holding its target range at 3.5 per cent to 3.75 per cent by 9 votes to 3, with Beth Hammack, Neel Kashkari and Lorie Logan preferring a rise of 25 basis points. The Fed sets the price of reserves; the maturity structure of the debt held outside the central bank is being adjusted by the fiscal authority, and the two instruments need not point the same way.[3]
After September 9
The background to the decision is a long end under strain. On Tuesday the 30-year yield reached 5.286 per cent, its highest since 2007, the most recent 10-year auction cleared at 4.683 per cent and the 30-year auction stopped at 5.216 per cent, while long yields in Japan, Germany and France rose the same day. Buying that paper back takes duration out of private portfolios at the point where they price it most expensively, and I read the operation the department describes in liquidity terms that way. One alternative survives the evidence: at 4 billion dollars an operation the amounts may be too small against the outstanding long-dated stock for the term premium to move measurably.[1], [4]
The test is observable and dated. The department said it will publish an updated tentative buyback schedule and set out future operation sizes at the Quarterly Refunding on November 4, 2026. If the enlarged operations are filled near 4 billion dollars in the 20-year to 30-year sector between September 9 and that date, the fiscal authority will have chosen to shorten the maturity of the outstanding stock while the total keeps rising. If they keep clearing well below the new maximum, the change will have amounted to the liquidity support the announcement describes, and the question of who carries duration will be where it was.[1]
