IMF warns of rising financial stability risks despite resilient global markets
The IMF identified a sharp rise in sovereign bond yields as another major threat to financial stability, saying the risk has worsened since its April 2026 report
WASHINGTON, October 14, 2026 — The International Monetary Fund [IMF] has warned that financial stability risks remain elevated despite resilience in global financial markets, citing growing vulnerabilities linked to artificial intelligence [AI], sovereign debt and cyber threats.
In its October 2026 Global Financial Stability Report, released in Bangkok, Thailand at the sidelines of the ongoing IMF-World Bank Annual Meetings, the IMF said financial markets had remained resilient since its April assessment, supported by strong corporate earnings and solid economic growth, particularly among AI-related firms.
However, the Fund identified three major risks that could trigger a sharp tightening of financial conditions and market turmoil: a correction in AI-related asset prices, a sharp rise in sovereign bond yields and severe cyberattacks.
“Financial stability risks remain elevated,” the IMF said, warning that the identified risks could become systemic if amplified by existing vulnerabilities in the financial system.
The report said weaker-than-expected or less durable investment and profitability in AI could trigger a correction in AI-related equities and credit markets.
It warned that leverage within the AI ecosystem has increased significantly. The share of global investment-grade bond issuance accounted for by hyperscalers [large cloud computing and data-centre operators] has risen to 10 percent, from less than 1 percent in 2024.
At the same time, hedge funds’ gross equity positions and equity margin loans have increased from 10 percent to about 15 percent of advanced economies’ gross domestic product [GDP] since 2024.
The share of single stocks in leveraged exchange-traded funds [ETFs] has also risen to 28 percent from 16 percent over the same period, increasing the risk of forced selling and greater market volatility if AI investment and profitability weaken.
The IMF also highlighted growing interdependence within the AI industry through so-called circular financing arrangements.
It said 14 publicly disclosed transactions since 2023 involved approximately US$300 billion in aggregate equity investments by hyperscalers in financially weaker AI firms, alongside US$650 billion in debt and US$1.4 trillion in future revenue commitments.
The Fund said such arrangements could create significant risks if financially weaker AI companies come under pressure.
Sovereign debt risks
The IMF identified a sharp rise in sovereign bond yields as another major threat to financial stability, saying the risk has worsened since its April 2026 report.
It said higher energy prices, inflation expectations and rising term premiums [the additional return investors demand to hold longer-term bonds] have pushed up government borrowing costs.
High government debt and refinancing risks remain unresolved, leaving bond markets vulnerable to renewed inflation and fiscal shocks.
The Fund warned that a sharp increase in bond yields could have wider consequences because government bonds underpin many financial markets.
Higher yields could reduce the value of financial assets, increase governments’ debt-servicing costs and put pressure on borrowers that need to refinance their obligations.
The IMF said the risks are particularly concerning for some emerging and frontier economies, where foreign exchange reserve buffers have weakened and reliance on alternative and often less transparent sources of financing has increased.
Among weaker emerging markets that are below investment grade and had reserve adequacy ratios below 100 percent, the median ratio fell from 72 percent in the first quarter of 2026 to 63 percent in the second quarter.
The Fund said reserve adequacy across most emerging markets remained below pre-war levels, despite some rebuilding through stronger trade balances, renewed capital inflows and bilateral financing arrangements.
Frontier economies have regained some access to international financing, with frontier sovereign issuers accounting for close to one-fifth of emerging-market sovereign bond supply in the first half of 2026.
But the IMF cautioned that unusually compressed spreads could mask repricing risks, particularly as the 10-year US Treasury yield remains above 4.5 percent.
Cyber threats
The report also identified cyber threats as a growing systemic risk as financial services become increasingly digital and interconnected.
The IMF said a major cyberattack affecting payment systems, trading platforms or access to deposits could cause immediate losses, undermine confidence and disrupt the provision of credit and financial services.
It warned that attacks on critical financial institutions, market infrastructure, cloud providers or software vendors could quickly spread through operational and financial linkages.
More than 70 percent of cases recorded so far in 2026 showed that software providers had almost no time to patch vulnerabilities before exploitation began, representing an increase of 20 percentage points from the previous year.
The IMF said the rapid digitalisation of financial institutions has expanded the potential attack surface, while shortages of cybersecurity professionals remain a major challenge.
Banks remain resilient
Despite the risks, the IMF said the global banking system remains broadly resilient.
Its global stress test found that banks would remain adequately capitalised under a scenario involving a spike in bond yields and an AI-led market correction, although a significant share of vulnerable institutions would emerge.
The Fund also warned that growing links between banks and non-bank financial intermediaries [NBFIs] could become a source of fragility during periods of financial stress.
The report said households were in a relatively stronger position, with debt burdens having declined across countries and household net worth increasing. However, a correction in housing or equity prices could weaken consumption and disproportionately affect lower-income households.
The IMF urged governments and financial regulators to strengthen resilience by containing excessive leverage, putting public debt on a sustainable path, improving bond-market infrastructure and liquidity backstops, and strengthening cybersecurity.
It also called on emerging and frontier economies to rebuild fiscal and external buffers and improve disclosure of alternative financing arrangements.
The Fund said policymakers should act proactively because fiscal and monetary policy space to respond to financial instability is more limited than it was during much of the past two decades, owing to high debt levels and persistent inflation in many economies.
