Nvidia’s $5.5B Hit: US Export Ban On AI Chips To China Shakes Global AI Race

Nvidia just took a $5.5 billion punch to the balance sheet—courtesy of the U.S. government’s latest move to tighten the leash on AI chip exports to China. The company’s most advanced processor available in the Chinese market, the H20, has now fallen under indefinite export restrictions, triggering a 6% slide in Nvidia shares in after-hours trading.

The decision, announced Tuesday, marks a major escalation in the U.S.-China tech standoff and underscores Washington’s growing concern over how AI hardware could fuel China’s supercomputing ambitions. The U.S. Commerce Department has now slapped licensing requirements not only on Nvidia’s H20, but also on AMD’s MI308 and similar chips. AMD shares dropped 7% after the news.

A Commerce Department spokesperson said the move reflects President Biden’s directive to safeguard U.S. national and economic security. Nvidia, meanwhile, confirmed the charges would cover unsold H20 inventory, outstanding purchase commitments, and related reserves.

A Workaround, Now Blocked

Nvidia had designed the H20 chip specifically to navigate around previous U.S. export limits—delivering toned-down performance but retaining high-speed interconnectivity. That design made the H20 attractive for AI inference tasks, an increasingly dominant segment of the market where models provide real-time answers rather than undergoing initial training.

Despite not being as powerful as Nvidia’s top-tier chips sold outside China, the H20 gained traction with major Chinese tech players including Tencent, Alibaba, and ByteDance. Reuters previously reported that demand surged after startups like DeepSeek ramped up development of low-cost AI models.

But that very design—optimized for high-bandwidth memory access and chip-to-chip connectivity—set off alarm bells in Washington. Analysts argue it still carries supercomputing potential, especially if deployed at scale.

“Likely In Violation”

A Washington, D.C.-based think tank, the Institute for Progress, didn’t mince words. In a statement Tuesday, it claimed that Tencent had already installed H20 chips in a facility likely used to train large AI models—potentially breaching U.S. export restrictions already in place. The group added that DeepSeek’s infrastructure, used for its latest V3 model, might also be in violation.

U.S. restrictions on chips used in supercomputing have been in effect since 2022. Now, the H20 is joining that list. Nvidia said it was formally notified on April 9 that the chip would require an export license—and on April 14, that the restriction would be indefinite. Whether the U.S. will issue any such licenses remains unclear.

A Fork In The Road

This latest move throws a wrench into Nvidia’s China strategy, just as demand in the region for generative AI tools is accelerating. It also highlights the growing friction between global innovation and geopolitical control—a tension Nvidia CEO Jensen Huang must now navigate carefully.

The setback comes one day after Nvidia unveiled plans to invest up to $500 billion into U.S.-based AI server infrastructure, working with partners like TSMC to align with American industrial policy.

Now, as Nvidia absorbs the financial blow and recalibrates, one thing is clear: the AI chip race isn’t just about performance anymore. It’s a front line in the broader battle over who controls the future of intelligent computing.

ECB Launches Geopolitical Stress Tests For 110 Eurozone Banks

The European Central Bank is preparing a new round of geopolitical stress tests aimed at assessing potential risks to major financial institutions across the euro area. Up to 110 systemic banks, including institutions in Greece and the Bank of Cyprus, will take part in the exercise, which examines how geopolitical events could affect financial stability.

Timeline And Testing Process

Banks are expected to submit initial data on March 16, 2026. Supervisors will review the information in April, while the final results are scheduled to be published in July 2026. The process forms part of the ECB’s broader supervisory work to evaluate financial system resilience under different risk scenarios.

Geopolitical Shock As The Primary Concern

The stress tests place particular emphasis on geopolitical risks. These may include armed conflicts, economic sanctions, cyberattacks and energy supply disruptions. Such events can affect banks through changes in market conditions, borrower solvency and sector exposure. Lending portfolios linked to regions or industries affected by geopolitical developments may face higher risk levels.

Reverse Stress Testing: A Tailored Approach

Unlike traditional stress tests that apply the same scenario to all institutions, the reverse stress test requires each bank to define a scenario that could significantly affect its capital position. Banks must identify a geopolitical shock that could reduce their Common Equity Tier 1 (CET1) ratio by at least 300 basis points. Institutions are also expected to assess potential effects on liquidity, funding conditions and broader economic indicators such as GDP and unemployment.

Customized Risk Assessments And Supervisor Collaboration

This methodology allows banks to submit risk assessments based on their own exposures and operational structures. The approach is intended to help supervisors understand how geopolitical events could affect institutions differently and to support discussions between banks and regulators on risk management and contingency planning.

Differentiated Vulnerabilities Across Countries

A joint report by the ECB and the European Systemic Risk Board indicates that countries respond differently to geopolitical shocks. The Russian invasion of Ukraine led to higher energy prices and inflation across Europe, prompting central banks to raise interest rates. Belgium, Italy, the Netherlands, Greece and Austria experienced increases in borrowing costs and lower investor confidence. Germany, France and Portugal recorded more moderate changes, while Spain, Malta, Latvia and Finland showed intermediate levels of exposure.

Conclusion

The geopolitical stress tests will not immediately lead to additional capital requirements for banks. Their results will feed into the Supervisory Review and Evaluation Process (SREP). ECB supervisors may use the findings when assessing capital adequacy, risk management practices and operational resilience at individual institutions.
