Rising Influence of Nonbank Financial Institutions Sparks Global Stability Concerns

Washington D.C., Tuesday, 14 October 2025.
The increasing role of nonbank financial institutions poses significant risks to global stability, with their interconnectedness to traditional banks amplifying potential shocks, as reported by the IMF.
Nonbank Financial Institutions: A Growing Concern
The role of nonbank financial institutions, such as insurance companies, pension funds, and investment funds, in the global financial system has expanded significantly. These entities now hold approximately 50% of the world’s financial assets, a figure that underscores their critical role as market makers and liquidity providers [1]. However, this growth has not come without its challenges. The interconnectedness of nonbanks with traditional banking systems means that any vulnerabilities within the nonbank sector can quickly transmit to banks, potentially amplifying financial shocks [1].
Regulatory Challenges and Stress Testing
The International Monetary Fund (IMF) has highlighted the need for stronger oversight of nonbank financial intermediaries. Stress tests conducted by the IMF reveal that vulnerabilities in the nonbank sector can rapidly affect the core banking system, complicating crisis management [1]. Some regulators, including those in the United Kingdom and Australia, have initiated system-wide stress tests and scenario analyses to better understand interactions between banks and nonbanks. These efforts have highlighted the necessity for improved data collection, stronger domestic and cross-border coordination, and regulatory innovations [1].
Potential Impacts on Global Financial Stability
The IMF’s Global Stress Test found that banks holding about 18% of global assets could see their Common Equity Tier 1 capital ratios fall below regulatory minimums under a stagflationary shock scenario. This scenario highlights the potential for adverse developments in nonbanks to significantly affect banks’ capital and liquidity ratios. Notably, about 10% of US banks and 30% of European banks, measured by assets, could see their regulatory capital ratios fall by more than 100 basis points [1]. Liquidity mismatches in open-ended investment funds could lead to forced bond sales, disrupting market functioning and spilling over into funding markets [1].
Call for Comprehensive Regulatory Measures
In response to these emerging risks, the IMF and other financial bodies emphasize the need for comprehensive, forward-looking approaches to risk assessment. Unlike traditional banks, nonbanks often operate under lighter prudential regulations, providing limited disclosures on assets, leverage, and liquidity. This lack of transparency makes it challenging to detect vulnerabilities and interconnections [2]. The IMF stresses that maintaining financial stability will depend on sound policies, resilient institutions, and timely risk mitigation steps, including controlling inflation, ensuring central bank independence, and regulating nonbank and digital assets [2].
