The headlines piled up back in the spring. They’ve thinned out since. The news cycle moved on to other things, the way it always does. The stress didn’t move on with it.
The U.S. private credit default rate hit 5.8% for the twelve months through January, the highest level since Fitch started tracking the metric. By the second quarter, Fitch’s own tracker had climbed to a record 6.0%. Around 40% of private credit borrowers now have negative free cash flow — not slow growth, negative. Thousands of PE-backed companies are stuck unsold for five-plus years, north of $860 billion in assets nobody can move. Blackstone’s flagship credit fund has now capped investor redemptions in back-to-back quarters. This quarter, holders asked to pull 10% of their shares and got half of that.
Back in the spring, one widely-followed markets account summed up the mood: “Private credit defaults are up 4x since 2024. This is the asset class’s first stress test. Investors are bracing for a blow-up.”
Notice the last word. Investors.
Every take, then and now, is about what the credit wave means for the people who lent the money. Almost nobody is talking about the companies that borrowed it: the portfolio companies inside these funds, where the stress test actually lands.
That’s the story worth telling. When credit tightens, the capital structure stops being an abstraction on a term sheet and becomes a set of operational consequences most diligence never modeled.
What’s happening in the credit market
Let’s be precise about the landscape, because the temptation to sound the alarm is high.
The default acceleration is real and it’s no longer a single alarming data point. It’s a documented trend: Fitch’s tracker has set new records in consecutive periods with no signs of reverting. And the current stress isn’t evenly spread. A meaningful share of it is concentrated in tech-adjacent direct lending, where slowing growth collides with the sudden realization that AI is eroding the competitive moat of mid-market software businesses that make up a large slice of some private-credit portfolios. If your portfolio company sells software or sells into software buyers, this isn’t background noise.
The PIK story has actually gotten more interesting than “PIK is rising.” Lenders regained enough leverage in 2026 that they’ve pulled back on offering payment-in-kind terms on new loans, down to roughly 13.5% of new originations in the second quarter, from a quarter of new loans at the end of last year. That’s not the crisis receding. It’s the opposite signal: when a lender won’t offer you the flexibility, it’s because they don’t need to compete for your business anymore. Meanwhile the back book, the wave of PIK-heavy loans written when terms were generous, is still working through the system. Those are the companies where the distance between “current” and “restructured” is closing fastest.
The institutional cracks are visible too. Blackstone’s BCRED has now gone through multiple consecutive quarters of gating redemptions. Investors keep asking to leave; the fund keeps only letting half of them out. The fund’s own messaging says the underlying portfolio companies are performing fine. That claim is worth exactly as much skepticism as any claim a fund makes about its own book during a stress period. And the mechanism that made this obvious back in the spring hasn’t changed: a private loan can look fine on a mark and be worthless a quarter later. There’s a line from that period that stuck with me: “In private credit, the distance between ‘perfectly fine’ and ‘worthless’ is roughly 90 days.” That’s not a market observation. That’s an operational warning about how fast a business can deteriorate once the assumptions underneath it stop holding.
Now, the counterweight — because getting this wrong in the alarmist direction is a credibility problem.
John Caple, who invests in this space, pushed back hard on the doom narrative back when the headlines were loudest. His point: more PIK features are available in loan documents, so more borrowers using PIK isn’t automatically a red flag. Only 15% of deals had interest coverage ratios below 1.0. The large majority were covering their payments. And the largest bankruptcy everyone pointed to wasn’t a PE deal at all, and it sat in the broadly syndicated market, not the private debt market. His conclusion: “I don’t see the signs of broad issues… let’s not jump to conclusions based on some snappy X posts.” The most recent coverage-ratio data actually backs him up further. The share of deals below that 1.0 line has kept falling, not risen, since he said it.
Take that pushback seriously. It’s why this piece isn’t a macro prediction. But here’s the thing about a stress test: it doesn’t have to be systemic to end your specific company. A shrinking minority of deals in trouble is still cold comfort if yours is one of them, and the 40%-negative-free-cash-flow number says the minority isn’t as small as the headline-cooldown makes it feel. Whether the market blows up or muddles through, concentrated stress in your portfolio is still your problem.
The operational cascade nobody diligenced
Here’s what the credit headlines don’t show: the chain reaction inside a portfolio company when its debt gets expensive and its refinancing stalls.
Capex gets deferred first. When debt service eats a bigger share of cash flow, maintenance capital is the first casualty. Equipment ages past its replacement window. Systems don’t get the upgrade the value-creation plan promised. The technical debt compounds quietly, and none of it shows up on a covenant report until something breaks.
Management gets distracted. Lender negotiations, covenant amendments, refinancing conversations — these consume CFO and CEO bandwidth that was supposed to go toward running the business. None of this makes the leadership team incompetent. It makes them busy with the wrong fight. The value-creation plan doesn’t pause while they’re in a conference room with the credit committee. It just quietly stops progressing.
Zombie dynamics set in. The same account that called this the asset class’s first stress test put it more bluntly: “private credit is keeping zombies alive.” Companies that should restructure get propped up instead: more PIK, more deferrals, one more amendment. Operations deteriorate while everyone at the table pretends the capital structure is fine. The pretending is the expensive part.
Cash gets extracted at the worst possible moment. Sponsors who can’t exit a company still need to show returns. Dividend recaps and management fees become the pressure valve, pulling cash out of the business precisely when the business needs investment most.
And the best people leave first. When employees see delayed projects, frozen hiring, and a spike in scrutiny from above, the strongest performers, the ones with options, head for the door. We’ve written before about how PE diligence routinely misses the turnover risk baked into a management team; credit stress is an accelerant on exactly that dynamic. Talent flight doesn’t wait for the restructuring. It front-runs it.
None of these five consequences is a financial-engineering problem. Every one is an operations problem. And almost none of them get stress-tested in diligence.
The blind spot: diligence validates the spreadsheet, not the resilience
Standard operational due diligence asks a growth question: Can this company grow EBITDA? It models the upside case, validates the value-creation plan, confirms the assets exist and the systems function.
What it almost never asks is the resilience question: What happens to operations if the capital structure comes under stress?
Nobody stress-tests operational performance at a reduced capex budget. Nobody quantifies the management bandwidth consumed by lender reporting when covenants tighten. Nobody flags which operational improvements in the plan require capital that may not materialize if refinancing stalls. Nobody asks what the value-creation plan looks like when the cheap debt it was priced against is no longer cheap or no longer available.
The result is a diligence process that validates the spreadsheet and skips the operations. Deal assumptions and operational reality diverge the moment credit tightens — and the gap between them is where portfolio companies get restructured.
This is the same blind spot we’ve mapped in the operational diligence work most firms skip entirely. Credit stress just raises the stakes. The lack of due diligence people now criticize in private credit was never only about loan terms. It was about the operational resilience of the underlying businesses: whether they could generate cash under pressure, or only looked like they could while capital was cheap.
The reframe: operational resilience was always the thesis
When credit is cheap, operational excellence is a nice-to-have. Financial engineering carries the returns. You can survive mediocre operating performance if the multiple expands, the debt refinances on schedule, and the interest gets paid in cash without anyone thinking twice.
When credit tightens, operational excellence is the only lever. The companies that weather the stress test share a profile: strong operational visibility, lean cost structures, capital allocation driven by data instead of habit, and management that isn’t dependent on external capital to keep the core business running. They can tell you, on any given week, exactly where their cash is going and what they’d cut first if they had to. Most of their peers can’t.
This is the on-the-ground consequence of the shift that has PE practitioners leaving deal seats to go run companies. That piece made the case through people voting with their careers: returns now have to come from operations, not the capital structure. The credit wave is the same argument arriving with a due date. Operational resilience stopped being a differentiator and became table stakes, and the companies that treated it as optional are the ones showing up in the default statistics.
Here’s the part worth sitting with: the operational discipline that gets you through a credit crunch isn’t something you can install in a quarter. Figuring out what good looks like — clean cash-flow visibility, honest unit economics, a real answer to “what would we cut first” — takes time to build. The companies that started before the stress test are fine. The ones starting now are already behind.
The stakes
The credit cycle doesn’t care about your value-creation plan. It doesn’t care what your model said the refinancing would look like, how many tabs of upside case you built, or how confident the deal team was that the covenants would hold.
When capital tightens, one question survives: can your operations generate cash flow without the tailwind of cheap debt?
If you can’t answer that with data — not gut feel, actual visibility into where cash comes from and where it leaks — you’re already exposed. The stress test is here whether your portfolio is ready or not. The only variable you control is whether your companies can see clearly enough to respond.
That’s the work. If you’re staring at a portfolio company and can’t tell whether it would survive its own capital structure under pressure, let’s talk. Building that visibility before the lenders start asking is a very different conversation than building it after.
