The $3 Trillion Private Credit Market Is Becoming A Problem

Private credit is a $3 trillion market right now. In 2009, it was $200 billion. That's 15 times growth in under 15 years. It's faster than private equity, faster than venture capital, and faster than real estate. It's actually the fastest-growing asset class in institutional finance, and most people outside of Wall Street have never even heard of it.

Private credit is lending that happens outside of the banking system. A company needs capital, and instead of going to a bank, they go directly to a fund - Blackstone, Apollo, Aries, Blue Owl, a fund like this. And these funds write the check, set the terms, and hold the loan. It doesn't get traded. There's no public market for it, no disclosure requirements, and usually no credit rating involved. The fund and the company have a direct relationship for the life of that loan. That's the basic structure of private credit.

The reason this market grew to the size it is today starts with 2008. After the financial crisis, regulators forced banks to hold more capital, take on less risk, and pull back from certain types of lending. Banks got more conservative, and a large part of the market - like midsize companies, borrowers without perfect credit, anything with some complexity - they found it increasingly more difficult to get loans from traditional banks. Private credit stepped into that gap.

At the same time, interest rates dropped to near zero after the crisis and stayed there for years. For large institutional investors - pension funds, insurance companies, endowments - that meant the return on traditional bonds and fixed income were too low to meet their obligations. They needed better yields. Private credit was offering returns roughly two percentage points higher than comparable public debt.

That combination of factors - banks pulling back and investors hunting for yield - is what drove the explosive growth.

The performance numbers have held up as well. Over the last 10 years, direct lending, which is the largest part of the private credit market, has delivered higher returns with lower volatility than both leveraged loans and high-yield bonds.

During periods when interest rates were rising, direct lending averaged returns of 11.6% - about two points above its long-term average. Even in late 2024, when the Federal Reserve was cutting rates, direct lending returned over 10% annualised, beating public alternatives.

Credit losses have also been lower than in the public markets. Senior direct lending has averaged annual losses of around 0.4% since 2017, compared to 1.1% for leveraged loans and 2.4% for high-yield bonds. A big reason for that is the direct relationship between lender and borrower - problems get caught and addressed earlier.

The market is projected to reach $5 trillion by 2029. McKinsey estimates the total addressable market in the US alone could be over $30 trillion when you account for how much lending could eventually shift from banks to private credit funds. That shift is already happening and it's still really early.

In terms of where money is moving right now, a few areas stand out:

The investor base is also changing. Insurance companies are building their own lending operations. Large asset managers are buying insurance companies to access longer-term capital. And for the first time, retail investors are getting access through business development companies, interval funds, and now private credit ETFs.

State Street and Apollo launched the first private credit ETF earlier this year, with the SEC allowing up to 35% of the fund to be in illiquid assets. That's a significant change from standard ETF rules and it signals how mainstream this asset class is becoming.

The risks are worth being honest about though.

Transparency is the biggest structural issue right now. These loans aren't publicly disclosed. So when a borrower starts to struggle, the market often doesn't find out until things are already bad. A recent example was Renovo, a company that was carried at full value on most books, then written down to zero almost overnight. When there's no public market pricing a loan every day, you don't always know what you have until something goes wrong.

Lending standards are another concern. As more capital has poured into private credit, competition among lenders has increased — more funds chasing the same deals means that some are doing loans they probably shouldn't. Payment-in-kind loans, where a borrower adds unpaid interest onto their debt balance instead of paying it in cash, are also becoming more common. That's generally a sign of a borrower under pressure.

Leverage is also rising, both within private credit funds and among the companies they lend to. Banks have lent over a trillion dollars to private credit funds. So if things go wrong inside the private credit market, there's a real connection back to the traditional banking system.

The retail expansion creates another risk that didn't exist before at this scale. Private credit is by nature illiquid — these loans can't be sold quickly. But new retail products are being built with easier redemption features. If investors get nervous and try to pull money out quickly in a downturn, funds may have to gate, which means they restrict or delay withdrawals. That tends to make investors more nervous, not less, which creates a feedback loop that's hard to stop once it starts.

The broader context is that private credit has never been through a serious economic downturn at anything close to its current size. The stress events it's seen so far have been manageable and contained. What happens to this market in a real recession — rising unemployment, falling revenues, compressed deal activity — is still an open question for anyone evaluating where to put capital or helping others do that.

The return story for private credit is very well documented and it's compelling to say the least. The more important question now is: who is managing it and how? What does their loss history actually look like? Have they had to work through a bad loan before? What protections are built into their loan agreements?

That's where the difference between managers shows up. And in a harder environment, that difference is going to matter a lot more than it has over the past decade.
