Core message: Financial markets have remained resilient amid solid economic growth and strong corporate earnings, but three key risks have been increasing with potential for broader implications: an artificial intelligence-driven market correction, a sharper rise in sovereign bond yields, and cyberattacks. Underlying vulnerabilities could determine how damaging the manifestation of these risks would be, as detailed in the latest Global Financial Stability Report.

AI has become an important support for the global economy and financial markets, including investment in data centers, semiconductors, and related infrastructure, and exceptional earnings growth from companies driving the AI boom.
Risk scenario: Faltering AI investment and profitability could challenge optimistic expectations and trigger a correction in asset prices linked to the AI industry.
Leverage and circular financing:
- Review of 14 such transactions since 2023 found about $300 billion in equity investments and $650 billion in debt, in exchange for $1.4 trillion in future revenue commitments.
- Hyperscalers are borrowing more; investors have been leveraging to invest in AI stocks.
- Circular financing arrangements involving equity and debt flows between AI firms could mean stress at key companies receiving investment would lower revenue forecasts and investment valuations, weakening the value of the accumulated debt in those deals.

Sovereign bond yields have risen amid renewed inflation pressures from higher energy prices, fiscal concerns, and, in some cases, stronger-than-expected economic growth.
Possible normalization: Yields may be moving back toward levels seen before the global financial crisis.
Amplification channels:
- Risks of adverse feedback loops related to higher fiscal imbalances and leveraged trades in bond markets are increasing.
- Central bank balance sheet reductions and greater reliance on price-sensitive investors could contribute to further yield volatility.
- Consequences extend beyond public debt: higher yields could raise discount rates and depress valuations across other assets, including AI-related assets, while reducing the value of bonds used as collateral.

As finance becomes more digital and interconnected, cyber disruptions have emerged as a growing source of systemic risk capable of disrupting payments, trading, access to deposits, or other critical financial services.
Scope and contagion: A major incident affecting a major financial institution, payment system, cloud provider, or software platform could allow disruption to spread through an increasingly interconnected financial system.
Recent trends in vulnerability exploitation:
- In more than 70 percent of reported cases so far this year, software providers had almost no time to patch vulnerabilities before attackers exploited them.
- That’s more than double the share in 2021, when providers typically had close to 300 days to fix vulnerabilities.
Frontier AI models could accelerate both attacks and defenses, increasing the importance of cyber resilience, incident reporting, crisis preparedness, and oversight of critical third-party providers.

Banking sector stress:
- Under the Fund’s adverse stress scenario, global banks remain resilient overall, but banks with 22 percent of global banking assets would emerge with post-stress capital ratios below regulatory limits, an increase from 18 percent a year ago.
- Links between such banks and nonbank financial intermediaries are deepening, creating additional channels for transmitting stress.
Nonbank vulnerabilities:
- Pension funds and insurers have increased allocations to illiquid assets and derivatives and rely more heavily on the same asset managers, increasing the risk of simultaneous asset sales and margin pressures.
- Some institutions hold illiquid private credit, adding another potential amplification channel.
- Direct-lending funds have committed to provide funding on demand; if financial conditions tighten, borrowers could draw on those facilities while providers face liquidity pressures, reducing credit to companies that need it most.
Emerging and developing economies:
- Bond yields have risen, although spreads with advanced economy peers remain fairly compressed.
- Recent global shocks have diminished buffers, increasing external vulnerabilities and reducing the ability to absorb stress.

Context: With government debt high, inflation pressures re-emerging, and higher borrowing costs, policymakers have much less room to support the economy following shocks than in the past.
Three priorities for action (as stated):
- Debt needs to be put on a sustainable path.
- Leverage and liquidity mismatches in AI, private credit, and other nonbank financial sectors should be limited, including through sectoral capital and concentration requirements on banks’ exposures to these sectors.
- Cyber defense capabilities need to be strengthened, for example through better incident reporting and resilience testing among financial institutions.
Additional recommendation: Emerging and developing economies should rebuild buffers while financial conditions remain accommodative; proactive policies are the best way to prepare as risks are rising.
