Why "Really Bad Underwriting" Is Catching Up in 2026

Private credit sounds simple: a company borrows from a fund instead of a bank. For years, that setup looked like a win for everyone. Borrowers got fast money, investors got higher yields, and banks avoided some risk.

In March 2026, people are nervous because the easy part is over. Rates rose, growth slowed, and some borrowers missed the plans that made their loans look safe. That stress has brought a wave of headlines about redemption limits, loan markdowns, and arguments about whether some funds are valuing loans too generously.

Christian Stracke of PIMCO has summed up the mood with a blunt diagnosis: this isn't "mystery risk." It's a cycle where weak underwriting meets reality, and reality usually wins.

How private credit got so big after 2008, and why that matters

After the 2008 crisis, banks faced tighter rules and higher capital needs. That didn't kill demand for loans, it just pushed a lot of it elsewhere. Private lenders stepped in and grew quickly, first in the middle market, then into much bigger deals.

In plain English, direct lending means a fund makes a loan straight to a company (often one owned by private equity). A private credit fund pools investor money, makes loans, and collects interest.

Depending on how you count strategies and vehicles, the market is often described as roughly $2 trillion to $3 trilliontoday. That size matters because it connects more investors to an asset class that's harder to price, harder to trade, and easier to misunderstand when fear spreads.

From small business loans to mega deals (data centers, buyouts, and AI bets)

As more money chased deals, many lenders moved up-market. The story shifted from smaller loans to huge financings tied to buyouts, data centers, and AI-related buildouts. Bigger deals can be fine, but they're often more complex. They also invite tighter competition, which can tempt lenders to accept weaker terms just to "win" allocations.

High yields pulled in more capital. Those returns looked steady, so some investors began to treat private credit like a calmer version of public bonds. That's where trouble starts, because a loan can look calm right up until the borrower can't refinance.

A lot of underwriting also leaned on growth assumptions. When projections become the foundation of the deal, the loan gets "priced for sunshine." If clouds show up, the structure has less room to bend.

The liquidity mismatch problem, loans can take years, investors want cash fast

Private loans don't trade much. They're more like selling a house than selling a stock. You can sell, but it takes time, and you might hate the price if you need cash fast.

Some funds, especially those marketed more broadly, offer regular repurchases or periodic withdrawals. That can work during calm periods. It becomes a problem when many investors ask for money at once. A fund can't instantly unload a stack of bespoke loans without taking a discount.

To manage that, funds may use limits on withdrawals. Those limits exist for a reason. Still, when investors hit the "sell" button and get told "not yet," confidence can crack fast.

Here's a simple way to think about common fund setups:

Fund structure (simplified)	Typical liquidity	Why it can matter in stress
Closed-end style	Low	Less forced selling, but investors feel locked in
Interval style	Scheduled repurchases	Can trigger "rush to the exit" when limits hit
Open-ended style (with gates)	More frequent requests	Works until requests surge, then gates appear

The takeaway: loan liquidity and investor liquidity aren't the same thing, even if marketing makes them feel close.

What "really bad underwriting" looks like, and why it is showing up now

Underwriting is the process of judging risk and setting loan terms. It answers basic questions: How stable is cash flow? What can go wrong? What protections does the lender have if it does?

Stracke's critique is that some private credit deals only worked if everything went right. That includes steady growth, smooth refinancing, and rates that didn't rise much. In other words, the loan depended on a perfect chain of events.

Now we have higher rates and slower growth. That squeezes borrowers from two sides. Interest costs rise while sales and profits may not. The stress doesn't always show up as an instant default. Instead, it shows up as amendments, delayed exits, valuation disputes, and investors asking for their money back.

When a loan needs perfect conditions to work, it isn't "conservative private credit." It's a bet wearing a suit.

Over-optimistic projections, weak protections, and loans priced for a perfect world

Bad underwriting doesn't always mean the lender ignored risk. Often, it means the lender assumed away risk. A few patterns keep showing up in stressed credits:

Cash flow forecasts can miss by a mile. Management teams often believe their own plans, and lenders may accept those plans too easily. Some deals also used "add-backs" that inflate earnings, which makes leverage look lower on paper.

Protections weakened as competition increased. "Covenant-lite" structures (fewer ongoing financial tests) can reduce early warning signals. Loose collateral terms can also limit recovery value if things break.

Refinancing risk is the quiet killer. Many borrowers expected to refinance at similar or cheaper rates. When rates stay higher, a company can survive operationally yet struggle to roll the debt. That's how you get stress without an immediate bankruptcy headline.

The short-term benefit of loose terms is simple: more deals close. The long-term cost shows up later as lower recoveries and more surprise losses.

When "technical details" fail, fraud risk and sloppy controls get expensive

There's also a less glamorous part of underwriting: the technical checks. That means verifying where cash sits, who owns which assets, whether liens are real, and whether collateral is properly documented. It's boring, but it's where lenders protect themselves from ugly surprises.

Stracke has warned that sloppiness in these "technical defenses" can be a real problem. Weak controls raise the chance of misstatements. In worst cases, they can open the door to fraud. That doesn't mean every manager cuts corners. Still, a few blowups can poison the whole well because private credit is opaque.

Opacity creates a nasty loop. One loan gets marked down hard, and people assume the next one is just as bad. When investors can't easily verify prices, they fill the gaps with fear.

Why redemptions, gates, and markdowns are spooking investors

A "gate" is a limit a fund can put on withdrawals or repurchases during heavy demand. Think of it as crowd control. The fund tries to avoid selling loans fast at bad prices.

In early 2026, gates and limits have become a recurring theme. Several managers have reported elevated repurchase requests or restricted withdrawals in certain vehicles. Blackstone's large private credit fund, for example, said repurchase requests exceeded the usual quarterly amount, so the board increased the offer up to the maximum allowed without changing terms. Blue Owl restricted withdrawals in a private credit vehicle. BlackRock also curbed withdrawals after a surge in requests, and reports have flagged similar pressure elsewhere.

Banks are reacting too. JPMorgan has reportedly marked down certain loans tied to private credit groups and tightened its lending to the sector. When banks step back, it can squeeze liquidity even more.

Liquidity rarely makes headlines in good times. In stress, it becomes the whole story.

The domino effect, people panic when they cannot see prices

Private loans don't have a live ticker. Many are valued using models, comparable trades, and periodic reviews. That can be reasonable, but it also means marks may adjust slowly. Meanwhile, public markets can reprice in a day.

When investors see public debt prices falling for similar companies, they start wondering if private marks are lagging. That's how a few headlines can turn into a broader "something's wrong everywhere" feeling.

Stracke has made the point that this assumption is often wrong. Not every book is rotten. Still, limited transparency makes it hard for outsiders to separate strong managers from weak ones in the moment. Fear spreads faster than facts when prices are fuzzy.

Blue Owl Private Credit Valuations Questioned By Glendon, why marks matter

The phrase Blue Owl Private Credit Valuations Questioned By Glendon captures a bigger anxiety: are some private credit portfolios marked higher than where comparable risk trades in public markets?

In the reported debate, the critic argued that certain loans appeared valued above public pricing signals tied to the same borrowers or similar credits. That raises a fair question about whether reported loss rates and returns reflect current reality or a smoother, slower-moving valuation method.

This doesn't prove wrongdoing. Valuation is hard when assets don't trade. Two smart people can disagree, especially during stress. Still, marks matter because they shape investor behavior. If investors believe marks are optimistic, redemption requests can accelerate. That forces funds to defend liquidity, which fuels more fear.

In other words, valuation debates can become self-fulfilling. Confidence drops, withdrawals rise, and gates become more likely.

What happens next, a slowdown in lending, and lower returns may be the real outcome

The base-case outcome isn't necessarily a total collapse. A more realistic path looks like a grinding reset: fewer deals, tougher terms, and more visible losses.

Stracke has suggested that, absent a deep recession, defaults could run at mid-single-digit rates for a couple of years across bank loans and private credit. That could translate into low single-digit losses per year, which pulls average returns down. In that world, "10 percent-ish" expectations may turn into something closer to 6 to 8 percent, depending on manager skill and fees.

The knock-on effect is credit tightening. Lenders get pickier, demand better covenants, and charge higher spreads. Borrowers feel it quickly, especially those that need refinancing.

One response to the trust problem is better reporting. Apollo has said it's working toward more frequent net asset value updates for credit funds, starting with monthly disclosure and a longer-term goal of daily NAVs supported by third-party valuations. More light won't prevent losses, but it can reduce rumor-driven panic.

What smart investors watch, default rates, fund terms, and how pricing is done

If you're allocating to private credit now, focus less on glossy yield targets and more on the plumbing.

Start with the fund's redemption rules. How often can you request cash, and what limits apply? Next, look at valuation governance. Does the manager use third-party pricing, and how do they handle loans with public comps that move faster?

Risk also hides in concentration. A portfolio heavy in one hot area (like venture-style software, cyclical services, or a single sponsor) can crack when that pocket weakens. Fund-level leverage matters too. Borrowing inside the fund can boost returns on the way up, then magnify pain during drawdowns.

Finally, compare private marks to public signals when you can. It won't be perfect, but big gaps deserve an explanation you can understand.

Conclusion: Private credit isn't "broken," but it is being repriced

Private credit grew fast because banks pulled back and investors wanted yield. Over time, some loans got underwritten for perfect conditions, with rosy projections and weaker protections. Higher rates and slower growth exposed the weak spots, while opacity and redemption pressure turned stress into fear.

The key point is dispersion. Not every fund looks the same, and not every manager took the same risks. Still, terms are likely to tighten, returns may cool, and transparency will matter more than ever.

If you're investing in this space, match your liquidity needs to the product, then demand clarity on underwriting and valuation. That's where the next chapter gets written.
