BlackRock just marked another private loan from 100 to zero. That's not a typo. A loan that was supposedly worth full value one day is now worthless. And here's the kicker: this is the second time it's happened.
According to Bloomberg, BlackRock's private credit funds have now written down two separate loans to zero in recent months, raising serious questions about the transparency and risk management in the $1.7 trillion private credit market. When the world's largest asset manager is taking total losses on supposedly vetted loans, something is broken.
Let's be clear about what private credit is: it's corporate lending that happens outside traditional banks and public bond markets. Companies that can't or won't access public debt markets turn to private credit funds for financing. These loans are illiquid — you can't just sell them on an exchange — and they're supposed to be higher yielding to compensate for that risk.
The pitch to investors has been simple: higher returns with professional underwriting and less volatility than public markets because the loans don't get marked-to-market daily. That sales pitch just got a lot harder to make.
Here's why this matters. Public bonds and loans trade daily, so when a company gets into trouble, the price drops gradually and investors can see it coming. Private credit doesn't work that way. A loan can be marked at 100 — full value — right up until the moment the borrower defaults, and then it drops to zero overnight. There's no price discovery, no market signal, no early warning system.
BlackRock hasn't disclosed the identity of the borrowers or the loan amounts, which is standard practice in private credit but infuriating for anyone trying to assess systemic risk. What we do know is that these weren't small positions — you don't get news coverage for writing off a $5 million loan. These were likely in the hundreds of millions.
The $1.7 trillion private credit market has exploded over the past five years, driven by institutional investors and pension funds chasing yield in a low-rate environment. Banks pulled back from risky corporate lending after the 2008 financial crisis, and private credit funds filled the void. But unlike banks, these funds aren't subject to the same regulatory scrutiny, capital requirements, or stress testing.
That lack of oversight is starting to look like a problem.
When interest rates were near zero, private credit looked like a genius trade. Borrowers could afford high rates, and investors got attractive returns. But now, with rates higher and economic growth slowing, companies that took on expensive private debt are struggling to service it. And when they default, the losses are catastrophic because there's no secondary market to offload the risk.
BlackRock is hardly the only firm facing this issue, but they're the most visible. Other private credit managers are almost certainly sitting on loans that are worth far less than their stated value, but because of the way private credit accounting works, they don't have to mark them down until there's a definitive credit event — like a bankruptcy.
Cui bono? Nobody in the short term. Investors in these funds are realizing that "illiquid" was a polite way of saying "you can't get your money out when things go bad." Private credit managers are facing tougher questions from Limited Partners about risk controls. And regulators are starting to circle, asking why a $1.7 trillion market has so little transparency.
The broader concern is that we're only seeing the tip of the iceberg. If BlackRock — with some of the best risk management and underwriting talent in the business — is taking total losses, what's lurking in the portfolios of smaller, less sophisticated private credit managers?
This is the private credit version of what happened with subprime mortgages in 2007. Everyone assumed the loans were fine because they were marked at par, right up until they weren't. The difference is, this time there's no government backstop. When private credit blows up, investors eat the losses.
The numbers don't lie, but in private credit, they're allowed to stay quiet a lot longer than they should. BlackRock's writedowns are a warning: the illiquid credit market is under more stress than the official valuations suggest. Investors should be asking very hard questions about what else is hiding in the portfolio.
