SoftBank Bonds Buckle as the AI Stock Rout Spills Into Credit

The AI selloff just punched through into credit. SoftBank Group Corp.'s dollar bond due in 2032 slid 0.9 cents on Friday — its steepest one-day drop in 10 weeks, according to Bloomberg-compiled data. The notes landed among the biggest losers in Asia, and the Japanese technology investor's shares sank as much as 16%.

The pain wasn't contained to one issuer. Yield premiums on Asian dollar bonds widened by at least 3 basis points, traders said, a signal that investors are demanding fatter cushions to hold the debt.

The spark came from across the Pacific. A blowout in credit default swaps tied to some US companies behind the AI buildout set the tone, according to Bloomberg, dragging a stock-market rout into the bond market.

SoftBank sat at the front of the line for the damage — a familiar spot for a company whose fortunes traders treat as a live read on AI enthusiasm. Friday's move flipped that read negative, with its 2032 notes and its equity falling in tandem.

The wider spread move matters beyond SoftBank. Asian dollar bonds had been coasting on the same AI optimism that powered equities, and Friday showed how quickly that confidence can leak out of stocks and into the cost of borrowing.
