Britain has to sell government debt into the selloff
When two governments have to sell debt in the same week, the selloff stops being a number on a screen and gets tested by real buyers with real money.
The interest rate the US government pays to borrow for ten years settled on Monday at its highest level in 19 years (5.241%, up from 5.18% on Friday), after Trump rejected Iran's offer to reopen the Strait of Hormuz within seven days and Brent crude closed at $105.28 (WSJ). The line to watch is the level touched on June 12, 2007 (5.303%). Above that, Washington would be paying more to borrow than at any time since May 2002.
The more useful event is in London. On Tuesday the Debt Management Office, the arm of the British government that borrows on its behalf, sells up to £4.25bn of a bond that comes due in July 2036. The same bond sold last month at an average rate already the highest in nearly two decades (5.16%); the ten-year rate on British government debt hit 5.38% on Monday and stood at 5.41% on Tuesday morning, so this sale is set to clear at the highest rate since 1999 (Bloomberg). Traders expect the Bank of England, Britain's central bank, to raise rates in November, and next month's budget is expected to add spending rather than cut it.
An auction is where a selloff stops being a screen price and becomes a transaction. On a screen, a rate is whatever the last seller in the room accepted. At an auction, a government has to place the whole amount at whatever price the buyers demand, and it cannot wait for a better day. Last week a sale of US five-year debt ranked second-worst on record. This is the first time in the current move that a second of the big rich-country governments has had to test its ten-year borrowing rate at these levels, and the result was not known when we wrote.
What has not moved is the stock market. The S&P 500 is 1.3% off its high and the VIX, the market's gauge of how much turbulence traders expect over the next month, sits at 15.8, comfortably in calm territory; the ten-year rate was 5.226% on Tuesday morning, fractionally below Monday's close. Bonds are repricing the cost of money across the whole economy. Stocks have so far decided it is not their problem. One of those two is wrong, and the gap between them is why two groups keep falling while the index does not: the firms that run private credit and private equity funds, and the neoclouds, the smaller computing providers that rent out chips. Both are businesses whose shares are a bet on cheap money, made bigger with borrowed money.
