SoftBank plans record ¥1 trillion retail bond as AI credit stress mounts

SoftBank Group is preparing to issue approximately ¥1 trillion ($6.26 billion) in seven-year corporate bonds targeting Japanese retail investors, a deal that would be the largest retail corporate bond offering ever by a Japanese company, according to a Nikkei report cited by multiple outlets. The proceeds are earmarked for the conglomerate's expanding artificial intelligence investment program.investing+1

The announcement triggered an 8.1% drop in SoftBank shares on Wednesday, as analysts warned that rising borrowing costs directly threaten the economics of capital-intensive AI bets. The planned issue would be SoftBank's third retail bond sale this year, following offerings in April and June.telecompaper+1

Surging Yields Amplify Pressure

The bond plan lands at a difficult moment for borrowers globally. Japan's 10-year government bond yield touched 2.945% on Tuesday — its highest level since September 1996 — driven by inflation concerns and speculation that the Bank of Japan could raise rates as soon as September. U.S. 30-year Treasury yields simultaneously reached a 19-year high.reuters+1

The broader Tokyo market buckled under the strain. The Nikkei 225 fell as much as 3.1% in early Wednesday trading, with electronics and financial stocks bearing the brunt of the selloff.investing

AI Credit Stress Spreads

SoftBank is not alone in facing scrutiny. Nvidia's ↘ 1.84% five-year credit default swap spread climbed to 80.77 basis points as of August 19, surpassing its late-July peak and more than doubling since late May. Nvidia's next earnings report is scheduled for August 26, a date analysts view as a test of the company's AI financing narrative.finance.yahoo+2

Oracle ↗ 3.00% presents a starker warning. Its five-year CDS spread surpassed 200 basis points in July, roughly four times the investment-grade corporate index, after S&P downgraded its senior unsecured debt to one notch above non-investment grade.investing

Market Appetite Uncertain

Japan's retail-targeted corporate bond market is on pace to reach a record ¥2.8 trillion this year, according to Nikkei, suggesting household demand has not dried up. But the sheer scale of SoftBank's offering — with an expected coupon in the high 4% range and final terms yet to be set in early September — will test whether retail investors are willing to absorb AI infrastructure debt at a time when risk-free sovereign yields offer increasingly stiff competition.telecompaper+2
