Financial stability risks: cyber attacks, fiscal fragility, and AI concentration (with Francine Lacqua)

Tobias Adrian warns that AI accelerates cyber attack speed from months to minutes, creating vulnerabilities especially for smaller firms. The key medium-term risk is the interconnectivity between fiscal fragility (global debt approaching 100% of GDP) and financial stability. AI equity concentration is a concern but primarily equity-financed, not systemic like leveraged shadow banking.

Financial stability risks: cyber attacks, fiscal fragility, and AI concentration (with Francine Lacqua)

ndx

Adrian notes AI investment is equity-financed and profitability has been strong, but concentration and some leverage via debt create risks. The outlook is cautiously positive contingent on profitability persistence.

Global debt-to-GDP is approaching 100%. The shift from banks to leveraged investors in bond markets can amplify downside shocks.

Asks about cyber attacks requiring increased spending by companies and institutions.

Time between vulnerability discovery and exploitation has compressed from months to minutes. AI models accelerate attacks further. The question is whether defense or offense benefits more from AI.
Asks if this levels out, noting smaller banks haven't been able to look at the models.

Hard to see how it levels out globally. Smaller companies can't afford cutting-edge AI defense technology, leading to a rise in cyber vulnerabilities worldwide.
Asks about the single most important issue for financial stability globally.

The interconnectivity between fiscal fragility and financial stability. Global debt-to-GDP is approaching 100%. The question is how fragile the system is if adverse shocks hit.
Asks which countries are more at risk given market fragility.

Tobias Adrian

Countries are more at risk from dysfunction in longer-term bond markets. Financing has shifted from banks and insurance companies to non-banks and leveraged investors. This can be good for discipline but can also amplify downside shocks.
Asks about balancing fiscal discipline with the need for growth.

Structural policies work to enhance growth — reforming pension systems, labor markets, making economies more flexible. These are painful but necessary, especially amid a technological revolution.
Asks if a correction among big US AI companies would be a risk to financial stability.

Francine Lacqua
Tobias Adrian

On one hand, AI investment is primarily equity-financed, so a correction has macro impact but isn't like a leveraged shadow banking collapse. On the other hand, there is concentration and some leverage via debt financing. The key question is whether strong profitability will persist.
Asks if central banks lack a template for AI's impact on inflation, productivity, and jobs, leading to policy mistakes.

Francine Lacqua
Tobias Adrian

Central banks have powerful tools and clear mandates. They look at the world in real time and will be equipped to deploy tools to meet mandates. AI is about enhancement — making everyone more productive — and economic processes will readjust.

If markets are flexible, AI can create a lot of opportunities, but the right structural policy backdrop is needed.
