Private credit has been marketed as the adult in the room. Steady yield. Low volatility. No daily price swings. No flashing red screens. Just income dripping into portfolios while public markets throw tantrums.
But here is the uncomfortable truth.
Private credit did not remove risk.
It removed visible pricing.
When you do not mark assets every day, you do not eliminate volatility. You postpone it.
Now we are approaching the point where postponement meets physics.
Let’s start with leverage, because leverage is gravity.
Many private credit deals were structured at 7.5-8 times debt-to-EBITDA (which is high leverage, high risk).
Translation.
If a company generates 100 in operating cash flow, it may carry 750 to 800 in debt. That means it would take 7 to 8 years of current earnings to repay that debt, assuming nothing goes wrong.
Now imagine earnings fall 25 percent because AI compresses margins, replaces services, or forces pricing resets.
That 8x leverage instantly becomes 10x or worse relative to the new earnings level.
Interest does not fall just because earnings do.
So what happens?
- Interest coverage shrinks.
- Refinancing becomes harder.
- Creditors get nervous.
- Defaults rise.
That is why math becomes merciless.
High leverage is like thin ice. It holds beautifully until it doesn’t. And when earnings crack, the weight multiplies instantly.
This is not a traditional recession story.
In most credit cycles, demand weakens, GDP slows, and defaults drift higher. This time, the risk is structural. AI is not cyclical. It is disruptive. It is rewriting cost structures and competitive landscapes across software and tech-enabled services, which just happen to represent a significant slice of private credit portfolios.
Concentration is the accelerant.
History shows that one sector can drive the entire default cycle. Telecom did it in 2001. Energy did it in 2016. When a single industry accounts for the majority of stress, aggregate default rates can jump far faster than models predict.
Private credit today is heavily tilted toward services, technology, and healthcare. If software models reset, the impact will not be evenly distributed. It will cluster.
Clustering is how credit cycles go nonlinear.
Current default rates are hovering around 3 to 5 percent. That is not a crisis. That is elevated but digestible.
The concern is what happens if defaults move toward the mid-teens.
At that level, losses stop being portfolio noise and start becoming capital events.
And this is where the interconnection matters.
Private credit does not live in isolation. Borrowers often tap both private lenders and syndicated loan markets. The same sponsors recycle the same names across structures. The largest direct lenders also hold positions in leveraged loans and high-yield bonds.
So if private credit stress rises, it does not stay in a sealed compartment. Spreads widen in public markets. Liquidity thins. Risk premia reprice across the stack.
Then there are the balance sheets behind the curtain.
Banks and insurers have significant exposure to non-bank financial institutions. They lend to private credit vehicles. They provide undrawn commitments. They structure products around them.
In good times, that is diversification. In stress, there is a correlation.
If enough borrowers stumble at once, it becomes less about individual deals and more about system-level absorption capacity.
Now layer in the early warning signs.
PIK interest is rising.
PIK means the borrower is not paying cash interest. Instead, they add that interest to the loan balance. They are borrowing more to pay what they already owe.
That buys time. It does not solve the problem. It increases leverage further and shifts risk forward.
Interest coverage in many middle market deals sits around 1.7 to 1.8 times. That means earnings only cover interest less than twice over.
If earnings fall even modestly, that cushion evaporates.
At the same time, issuance could contract sharply in a stress scenario. If new credit supply drops and refinancing windows narrow, highly leveraged companies cannot simply roll their debt forward.
That is when defaults accelerate.
Opacity is the final multiplier.
Public bonds trade daily. Pain is visible in real time.
Private loans are marked periodically, often using internal models. That means deterioration can build quietly. When valuations finally adjust, it is rarely gradual. It is sudden.
The illusion of smooth returns disappears quickly when marks move.
None of this means we are in a crisis today.
It means the ingredients are assembled.
- High leverage.
- Sector concentration.
- Structural disruption.
- Interconnected lenders.
- Limited transparency.
Private credit was built in a world of zero rates and endless liquidity. It is now operating in a world of higher rates and technological upheaval.
That is a different equation.
The key point is simple.
When leverage is high and earnings are vulnerable, small changes create outsized consequences.
The surface still looks calm. The coupons are still being paid. The narrative still says contained.
But beneath that calm water, pressure is building along the seams.
And when highly leveraged structures meet structural earnings resets, the market does not negotiate with arithmetic.
It reprices it.
