Fifty-five days above five percent
A long end that stays above 5% quietly re-underwrites every asset priced off it, whether or not anyone remarks the book.
The yield on the 30-year Treasury has now settled above 5% on 55 days since the start of January — the most in any year since 2006, on Bloomberg's data. It touched 5.34% in mid-August, the highest since 2007 and within 10 basis points of a 22-year high, and sat at 5.27% on Tuesday (Bloomberg). The important word in that sentence is days. A yield spike is a headline; a yield that stays there is a repricing. Every private-credit loan, every data-centre lease, every leveraged buyout underwritten when the long end was at 4% is now being discounted against a curve that has held near 5.3% for most of a year. Treasury's response was to double its long-end liquidity-support buybacks, from $2bn to at least $4bn per operation in the 10–20 and 20–30 year sectors, running 9 September to 4 November. Worth being precise about what that is: the Treasury buys old, illiquid off-the-run bonds and funds the purchases with new issuance, generally bills. It does not reduce the debt. It swaps duration the market does not want for paper it does, and shifts supply toward the front end. Announced on 19 August, it moved yields for minutes; they had round-tripped by the following afternoon. What is not happening matters as much. The WSJ's own summary of the episode: no failed auctions, no dealer balance-sheet seizure, no forced unwinds, nothing resembling March 2020 or the gilt market in 2022. This is price pressure from deficits and supply, met with an official patch. It is a fragility story, not yet an ignition one.
