Japan Corporate Credit Risk Worsens by Most Since 2022

08:00 PM EDT, 10/28/2026 (MT Newswires) -- Japanese corporate credit risk has worsened by the most since September 2022 as AI-related credit concerns spread globally, Bloomberg reported Wednesday, citing data compiled by Bloomberg and Mizuho Securities Co. Five-year credit-default swaps on all 40 major Japanese companies tracked by Bloomberg rose from Oct. 1 through Oct. 28, led by SoftBank Group (SFTBY) and Nissan Motor (NSANY). The median increase was 12 basis points. "AI momentum has weakened, and concern is spreading across the market," Mizuho senior credit analyst Toshiyuki Suzuki told Bloomberg, citing credit concerns surrounding CoreWeave (CRWV). Japanese corporate bond sales hit a record 2.5 trillion Yen ($16 billion) in October and domestic spreads are at a roughly two-and-a-half-year high, the report said, while Mitsui Fudosan shelved a bond sale and NTT Finance Corp. raised less than expected.
