One day of relief, then the yields came back
The one policy tool that visibly calmed the long end last week has a half-life measured in hours, and the people who have to buy the bonds are saying so on the record.
On Wednesday the Treasury said it would at least double its liquidity-support buybacks of 10-to-30-year debt, from $2bn to at least $4bn per operation, running from 9 September to 4 November. The 30-year fell almost 10bp to 5.187%. On Thursday it climbed as much as seven basis points to 5.27%, briefly reversing the whole move. The mechanism the dealers are worried about is not the size of the buybacks. It is the surprise. Treasury has run a "regular and predictable" issuance policy since the 1970s on the theory that investors will pay more for debt when they know what is coming. This announcement landed two weeks after the quarterly schedule that was supposed to contain it. "We do not think it is hyperbole to say that this break in communication strategy reduces the overall credibility of their guidance," said Thomas Simons of Jefferies. JPMorgan's Jay Barry put the fiscal version: the US runs a 6% deficit in an economy near full employment, and absent consolidation "we fear the markets will view this action as lacking credibility." The arithmetic behind them: gross federal debt crossed $40tn this week, up $3tn in a year — the fastest pace outside the pandemic — with debt held by the public above $32tn, roughly the size of the economy. The New York Fed's term premium estimate is around 80bp, close to a twelve-year high. A buyback swaps illiquid old bonds for cash and is funded by issuing bills. It changes the composition of the debt, not its size. That works as plumbing. It does not work as fiscal policy, and Thursday's price action is the market saying it can tell the difference.
