Questions surrounding Nvidia CEO Jensen Huang and recent allegations have prompted a reassessment of the chipmaker's role in the global financial system. With the company having made hundreds of billions of dollars in commitments to support the artificial intelligence boom, some observers have dubbed it the central bank of AI. This significant influence means that any major issue at Nvidia could have far-reaching consequences for the broader economy and financial markets.

Federal Reserve officials and other financial institutions are closely monitoring the AI sector to understand how an unexpected event might impact global stability. Discussions among Fed officials as early as July included the possibility of a broad-based repricing of assets if problems emerged in the AI industry. While a repeat of the 2007 to 2008 financial crisis is considered unlikely, the sheer scale of Nvidia's obligations has regulators paying close attention to potential vulnerabilities.

Sheila Bair, a former FDIC chair, noted that Nvidia is not too big to fail in the same way a bank is. Unlike a financial institution that relies on public confidence, Nvidia still produces a physical product that customers want. The company's massive equity position provides a buffer against sudden losses. However, Bair emphasized that regulators must carefully track the exposure of banks and the wider financial system to Nvidia and similar firms, describing a potential collapse as a seismic event.

Investors remain optimistic about Nvidia's performance, with earnings scheduled for release on Tuesday. LSEG data indicates that analysts expect the company's revenue to more than double in the current fiscal year and to double again over the following two years. Despite these forecasts, the scrutiny facing Huang, who co-founded the company in 1993, has introduced uncertainty. His relationship with a woman suspected of spying for China has drawn attention from the FBI, Congress, and the company's board, raising the possibility of his removal.

Nvidia's stock price experienced a 30% decline from its October 6 peak through Tuesday's close, influenced by a broader reassessment of AI investments following the midterm elections. The stock recovered more than 4% by midday Wednesday. Experts who track financial flows in the AI sector suggest that even sharper losses would not immediately trigger systemic problems, but they remain vigilant about the potential for simultaneous reversals in the factors driving the AI boom.

Jason Wu, an assistant director at the International Monetary Fund, warned that the economy and financial markets are currently standing on the same leg. If the value of Nvidia's chips fell, it could trigger questions about the ability of companies that borrowed to buy those chips to repay their debts. This scenario could turn financial assistance from big tech firms into a burden, creating credit problems while equity values drop. Such issues would likely spread beyond tech portfolios to the wider economy.

The concept of circular financing is at the heart of these concerns. Nvidia has supported smaller AI firms known as neoclouds by committing to purchase cloud services, ensuring demand for its chips and helping those firms secure financing. Wu and other experts note that while these arrangements are productive during growth phases, a failure by Nvidia to honor its obligations could ripple through the borrowing firms and the banks that lent to them. The opacity of private credit funds involved in the AI boom adds to the complexity of the risk.

Recent stress has been visible in the neocloud sector. Credit-default spreads for CoreWeave debt nearly doubled from October 1 to November 5 before settling, while IREN's convertible bond price fell 23% amid a 26% drop in its share price. Beyond these relationships, Nvidia has a $105 billion phased guarantee for a data center project in Ohio and has promised to backstop up to $125 billion of a $500 billion credit program by Wall Street firms.

Stijn Van Nieuwerburgh, a finance professor at Columbia Business School, estimates Nvidia's total obligations at approximately $400 billion. While this is a substantial amount, it remains a small fraction of the company's $4 trillion market capitalization. Van Nieuwerburgh argued that the company would need to face near-extinction before all these guarantees were truly jeopardized. He noted that the system currently contains a significant amount of equity, which acts as a cushion against shocks.

In the short term, investors appear to view Nvidia's troubles as specific to the company, as many neocloud stocks have recovered even as Nvidia's share price has fallen. Long-term competition from firms like AMD, Intel, and Google may also limit the economic fallout by providing alternatives to Nvidia's chips. Nevertheless, central bankers remain anxious about the risks and are actively analyzing the structural vulnerabilities within the AI financial network.
