The rapid expansion of the global private credit market is drawing intensifying scrutiny from regulators, with the Financial Stability Board warning that opaque structures, rising leverage, and deepening ties to banks and insurers could transmit stress across the broader financial system during an economic downturn.
In a sweeping report released Wednesday, the Financial Stability Board said national regulators must strengthen oversight of the nearly $2 trillion private credit industry, according to CNBC. The FSB argued that risks are building in a market that has expanded rapidly but remains comparatively opaque and lightly tested under severe stress conditions.
The warning comes as concerns mount globally over deteriorating credit quality, rising refinancing pressures, and growing interconnectedness between private lenders and traditional financial institutions.

The FSB, which brings together central bankers, finance ministers, and regulators from G20 economies, said the sector’s lack of standardized data, inconsistent valuation practices, and increasingly complex funding arrangements are creating vulnerabilities that could spill into wider markets if economic conditions worsen.
The report is among the clearest signs yet that regulators are becoming increasingly uneasy about the speed and scale of growth in private credit, which has evolved from a niche financing market after the 2008 global financial crisis into a major pillar of corporate lending.
Private credit funds originally flourished as banks retreated from riskier lending activities following stricter post-crisis regulations. Alternative asset managers stepped in to finance mid-sized companies that struggled to access traditional bank loans.
But the market has since evolved far beyond that original role. Today, private credit increasingly finances larger corporations, leveraged buyouts, and complex acquisitions across sectors, including technology, healthcare, and business services. At the same time, exposure is spreading through the financial system via partnerships between banks, insurers, asset managers, and private equity firms.
The FSB warned that these growing interconnections could magnify instability during periods of stress. The watchdog identified multiple channels through which risks could spread, including bank credit lines to private credit funds, revolving facilities for companies already borrowing from private lenders, and expanding strategic alliances between banks and alternative asset managers.
“This includes riskier fund portfolio financing, banks providing revolving credit facilities to companies that are simultaneously borrowing from private credit funds, and private credit-focused partnerships between banks and asset managers becoming more common,” the report said.
The FSB estimated banks currently provide roughly $220 billion in drawn and undrawn credit facilities tied to private credit markets, although commercial industry data suggests actual exposure could be roughly twice as high.
While regulators said those amounts remain relatively small compared with total bank capital, the concern lies less in immediate size and more in the complexity and opacity of the linkages.
Unlike public debt markets, private credit transactions often occur with limited disclosure, fewer market price signals, and internally determined valuations. That makes it harder for regulators and investors to assess underlying risks or identify stress points quickly.
The FSB specifically flagged concerns around “payment-in-kind” structures, where borrowers pay interest with additional debt instead of cash.
“Some private credit borrowers also appear to be relying more on payment-in-kind loans, which can also signal deteriorating credit conditions,” the report stated.
Analysts increasingly view the rise of such structures as a warning sign that weaker borrowers are struggling with higher financing costs in a prolonged elevated-rate environment.
The timing of the report is significant because pressure is already emerging in parts of the U.S. private credit ecosystem, including software-sector lending, business development companies, and a growing number of stressed corporate borrowers.
The concern among regulators is that the industry has never been fully tested through a deep and prolonged global recession while operating at its current scale.
Much of the sector’s explosive growth occurred during an era of ultra-low interest rates and abundant liquidity. Higher rates now threaten to expose vulnerabilities in leveraged corporate borrowers that relied heavily on cheap financing.
The FSB also warned about liquidity mismatches in semi-liquid investment vehicles that offer investors periodic redemption opportunities while holding relatively illiquid private loans. That issue has gained attention recently in the United States after redemption pressures emerged in some retail-focused private credit products.
The shift toward retail participation marks another major structural change in the industry. What was once dominated largely by pension funds, insurers, and institutional investors is increasingly being marketed to wealth-management clients and individual investors seeking higher yields.
Regulators fear that this could increase the risk of investor runs during market stress. Central banks in Europe have already begun intensifying scrutiny. The European Central Bank and the Bank of England have both recently raised concerns about systemic vulnerabilities tied to private credit markets.
The Bank of England is already conducting stress-testing exercises with industry participants. Deputy Governor Sarah Breeden recently warned about risks surrounding asset quality, valuation discipline, and liquidity management. At the same time, major European banks have begun disclosing the scale of their exposures more openly during earnings season amid investor and regulatory pressure.
Barclays disclosed approximately $20 billion in private credit exposure, while Deutsche Bank reported about $30 billion, equivalent to roughly 2% of its total loan book. BNP Paribas said its exposure stood at around $25 billion, or approximately 3% of total lending.
The FSB stopped short of calling the sector an immediate systemic threat. However, the tone of the report suggests regulators increasingly believe the market’s rapid expansion warrants closer oversight before stress conditions expose weaknesses more forcefully. The watchdog is now urging national authorities to strengthen supervision around risk management, governance standards, exposure aggregation, valuation methodologies, and private credit ratings practices.
The broader concern is that private credit has grown into a critical source of global corporate financing while remaining far less transparent than traditional banking or public bond markets. That combination of scale, leverage, and opacity is increasingly unsettling regulators already wary of hidden fragilities emerging across the global financial system after years of cheap money and aggressive risk-taking.
