Costs to insure against Nvidia debt defaults hit a record high on Monday, as markets fret that its ongoing over $750 billion AI infrastructure deal could expand the company’s liabilities. ICE Data Services data shows Nvidia’s 5-year credit default swap (CDS) price climbed 14 basis points at one point to 82 basis points annually, marking the largest single-day jump for the swap since it began active trading last November. Last week, Nvidia announced its partnership with SK Group, parent of SK Hynix, tops $500 billion. Separately, Nvidia is in talks to provide up to $250 billion in guarantees for U.S. data center computing power projects leased by OpenAI, and may offer $350 billion in financing for OpenAI’s chip purchases. Sal Naro, chief investment officer at Coherence Credit Strategies, pointed out that AI infrastructure construction requires massive capital expenditure, and the bond market is facing a large volume of new supply. Markets are wary that opaque financing structures, off-balance-sheet transactions, and inter-corporate ties could trigger credit rating downgrades. Such financing typically demands investment-grade ratings, but firms like OpenAI and Anthropic are currently burning through cash at a rapid pace. Guarantees from large corporations can help AI infrastructure debt secure higher ratings; Broadcom previously provided most of the credit backing for a $35 billion chip financing deal for Anthropic.

South Korea's Financial Services Commission (FSC) Chairman Lee Eog-weon said the regulator will consider further measures to curb demand for recently launched single-stock leveraged exchange-traded funds (ETFs), which have been cited as one factor exacerbating stock market volatility. Lee noted he will assess the impact of a new policy that raises the minimum cash margin required for investing in single-stock leveraged ETFs to 30 million won (approximately $20,400), set to take effect this Friday. The South Korean government brought forward the implementation of this margin requirement by several weeks to stabilize the market and protect investors. Lee stated, "If demand does not cool sufficiently, we will also review and prepare additional measures in advance." As one potential measure, he proposed implementing aggregate position limits, which would restrict individual investors' holdings in such ETFs to no more than 20% of their total financial portfolios.
