Four billion a go, against two trillion of supply
The Treasury has now revealed the yield level at which it feels compelled to act, and the market erased the effect within 24 hours.
On 19 August the Treasury said it would at least double its liquidity-support buybacks of 10- to 30-year coupon debt, from a $2bn maximum to at least $4bn per operation, running 9 September to 4 November. The 30-year yield fell about 10 basis points to 5.1765% on the news. By the next session it was back to 5.247%. By Friday it was higher again — reports of the level differ, with the Washington Post putting it at 5.27% and Reuters at roughly 5.34%, the highest since 2007 either way (Washington Post). The mechanism matters, because a buyback is not quantitative easing. The Fed can create reserves; the Treasury cannot. It repurchases illiquid off-the-run bonds and funds the purchase by issuing something else, in practice bills. Net effect: duration comes out of private hands, the average maturity of the federal debt shortens, no new money enters the system. It is a swap, not a subsidy, and $4bn an operation is a modest one against a deficit running near $2tn a year and a debt stock past $40tn. The supporting evidence of strain is in the auctions, not the intervention. A $25bn 30-year sale cleared at 5.216%, the highest for that maturity since 2001; the previous day's 10-year drew the highest financing cost since 2007. Against all of which: the MOVE index sits at 8.99, down 18% in five days and 28% in twenty, and TLT is flat over the week. The options market is pricing an orderly repricing of term premium, not a liquidity event. Both things can be true — a market can reprice calmly to a level that is nonetheless a fiscal problem. What the buyback tells you is where Washington's pain threshold is.
