What Is Private Credit? How Non-Bank Lending Became a Trillion-Dollar Market — and Why Regulators Are Uneasy

What is private credit and how does it differ from bank lending?

Private credit is non-bank financing extended directly to companies, mainly through specialist credit funds, and it typically takes the form of long-term, floating-rate loans to middle-market and smaller companies that cannot access capital markets or bank creditCITE:E1. Unlike a syndicated bank loan, the lender in a private credit deal is usually a dedicated fund rather than a depository institutionCITE:E1.

How big is the private credit market and how fast is it growing versus bank lending?

Private credit has expanded from a niche pool of capital into a market the OECD says is now equivalent to 12% of bank loans to non-financial corporations, up sharply from 5% in 2012CITE:E2. The IMF separately estimated that the global private credit market topped $2.1 trillion in assets and committed capital in 2023, describing it as one of the fastest-growing segments of the financial systemCITE:E3.

Who are the leading players in private credit?

Apollo and Blackstone stand out as leading private credit managers, and the two firms jointly led what they called the largest private financing ever executedCITE:E4.

How is private credit linked to the traditional banking system?

The largest U.S. banks have sharply increased their committed credit lines to private credit vehicles — direct lending funds and business development companies (BDCs) — with those commitments rising about 145% over five years to reach roughly $95 billion as of the fourth quarter of 2024CITE:E5. These loans to private credit vehicles carry higher interest rates than typical bank lending, yet the Federal Reserve notes their default rates have run lower than bank loans to other non-bank financial institutionsCITE:E5.

How is private credit financing AI infrastructure and compute?

Private credit has become a direct funding channel for AI data-center buildouts, with Apollo leading and Blackstone and major global banks joining to provide $35 billion in initial capital for Broadcom's AI XPV PlatformCITE:E6. The Platform is designed to enable more than 20GW of compute capacity for frontier AI labs through 2028, and it will help facilitate Anthropic's previously announced expansion of over 1GW of compute infrastructureCITE:E6.

What risks are regulators flagging about private credit?

Federal Reserve Governor Lisa Cook said Fed staff estimate the private credit market has roughly doubled in size over the past five years, and warned that its increased complexity and interconnections with leveraged financial entities create more channels through which unexpected losses in private credit could spread to the broader financial systemCITE:E7.

What this means

The same growth trajectory that took private credit from 5% to 12% of bank corporate lending in a decadeCITE:E2 and pushed the market past $2.1 trillion by 2023CITE:E3 is also the trajectory the Federal Reserve says has roughly doubled the market in five yearsCITE:E7. That growth is not happening at arm's length from banks: banks' own committed credit lines to private credit vehicles rose 145% over the same window to about $95 billionCITE:E5, even as those vehicles now channel tens of billions of dollars into AI compute financing such as the $35 billion Broadcom AI XPV PlatformCITE:E6. The Fed's interconnection warningCITE:E7 and the scale of bank exposure to private credit vehiclesCITE:E5 describe the same structural link from two different vantage points.
