Company debt stops being the safe place to hide
If company debt reprices alongside government debt, the hundreds of billions of dollars of AI borrowing that still need buyers meet a less forgiving market.
The extra interest companies worldwide pay to borrow compared with governments widened by about 0.05 percentage points this week, the biggest move since March, leaving it at its widest in six months on a Bloomberg index. The equivalent gap for Asia's safest corporate borrowers opened Friday another 0.02 to 0.04 of a percentage point wider (Bloomberg). A twentieth of a point is not a rout. The reason it matters is the trade it undoes.
For the past year the fashionable view was that a company like Microsoft was a safer borrower than most governments, and company borrowing costs stayed close to government ones even as government bonds slumped. That worked while the supply of new company debt was manageable. It is not now: Paramount Skydance's $41bn of bonds sold to pay for a takeover fell as soon as they began trading, SoftBank ran a huge sale of debt too shaky to be considered safe to fund its AI push, and record new borrowing is colliding with investors who have started worrying about what companies owe. "It's that choppiness that keeps people away from the market," said T. Rowe Price's Sheldon Chan. Last week the Bank of England put AI-related borrowing at $450bn for the year to September; that supply has to be absorbed by someone, at some price.
The same selloff reached the market that is supposed to be asleep. American state and city bonds, measured by the Bloomberg Municipal Bond Index, lost about 4.4% in September, their worst month since Lehman collapsed in September 2008, with the interest rates on them at their highest since at least 2011 (Bloomberg). Thursday brought a second day of relief, the ten-year rate on those bonds falling 0.07 percentage points to about 4% and the thirty-year to 5.2%, as cash came back into the funds that hold them.
Our own numbers say the same thing more slowly: the extra interest paid by the shakiest companies stood at 3.12 percentage points on Wednesday against 2.7 in mid-September, wider every day this week. That is still less than half the 8 percentage points a crash trigger needs, and the move is orderly. But the one corner of the market that had been pricing no stress at all has begun to price some. That nudges the odds up on the fragility side: the buyers the AI borrowers need have just become choosier.
