This time last week, I conjured October’s “roach” scare in the course of suggesting that unlike a pair of idiosyncratic blowups tied to outright fraud in the auto sector last year, jitters around private credit in 2026 aren’t something to be dismissed out of hand.

Fraud’s a fact of life and a fact of lending. No matter how scrupulous you are, and no matter how rigorous your underwriting, you’ll get duped every now and again. Everybody plays the fool sometime.

There’s no exception to that rule. Not even Jamie Dimon, whose wholly unoriginal remarks about pest infestations contributed significantly to the angst which undercut a hodgepodge of regional lenders in and around the First Brands and Tricolor debacles in October.

Dimon issued a similar warning this week, when a third apparent roach skittered onto investor radar screens: London-based Market Financial Solutions Ltd.

Right off the bat — and without trying to cast any misplaced aspersions while engaging in some good-natured humor — the name’s a red flag. All products and services purport to solve a problem, and there are indeed situations where it makes sense to use the word “solutions” in your company name.

Say, for example, you’re a local roofer and you’re not very creative. You might very well call your company “Roofing Solutions.” Roofing Solutions works because the constellation of roof-related problems is relatively limited, which means everyone — from your prospective customers to your lenders — has a pretty good idea what you mean by “solutions.” And without your even having to elaborate.

(“Hello, I’m your local loan officer, how can I help?” “I’d like a small business loan.” “Ok, what do you do?” “I’m a roofer. Let me explain.” “That’s ok, I think I get it.”)

By contrast, the galaxy of problems covered by the terms “market” and “financial” is very large. Put the two together — i.e., “Market Financial” — and you’re talking about an infinite universe of prospective problems looking for solutions. Or, in some cases, solutions looking for problems. Given that, the company name Market Financial Solutions has no meaning, precisely because it could mean anything.

But what does it mean? What does Market Financial Solutions actually do? Or what did they do before the UK forced them into insolvency? Well, in a nutshell, they provided bridge loans for real estate deals. Or, to quote one generic summary, they funded “complex, fast-turnaround property transactions” using Wall Street’s money.

If your question’s “What went wrong?” there’s your answer. That is: The facts of this particular episode are the joke. Who lends a billion dollars to a company called Market Financial Solutions for the purposes of “complex, fast-turnaround property transactions”? Only Wall Street. Greed very often intersects with dumb, and when it does… well, “Ha, ha.” And on repeat.

I hate to be that overtly dismissive, but what do you want from me? Who am I, Matt Levine? I don’t harbor a conceited affinity for Wall Street, and thus don’t feel compelled to pen apologies for its behavior dressed up as snark. (And yes, that’s what his column is.) Wall Street’s a glorified racket that engages in habitual, greed-driven fuckery.

When that “model” results in manifestly dumb outcomes, I see no reason to flex my analytical skills in the service of making something dumb sound like something clever that just happened to turn out poorly. In this case, Wall Street loaned hundreds of millions of dollars for quick-fix property deals to a firm whose name sounds like it should be sandwiched between Subway and Great Clips on a strip mall pylon sign. Guess what happened?

Not all of the banks and private equity firms caught up in this are household names, but it looks like most of them are, and the ones that aren’t appear to have some connection to the firm itself. Among big name institutions chasing recoveries: Barclays, TPG, Jefferies, Wells Fargo, Banco Santander and Apollo, through a subsidiary that specializes in asset-backed lending.

I’d say those firms should’ve known better, but that’d be naive. They did know better. After all, they’re heavyweights in the business of providing market financial solutions, common noun. As such, they knew damn well that it was risky to facilitate Market Financial Solutions, proper noun. But they did it anyway, because there was some spread there.

That’s all banking is. Spreads. Risk management boils down to one question: Is the spread worth the risk? You can hire all the rocket scientists you want, but that’s not an exact science even when there’s no fraud involved. When there is fraud involved, all bets are off.

So what happened here? With Market Financial Solutions, I mean? The same damn thing that happened with Tricolor and the same thing that, in one way or another, happens in most financial fraud: The same collateral was used to secure multiple obligations. Allegedly.

Conceptually speaking, almost all financial fraud revolves around double- or multi-pledged collateral, it’s just a matter of how strictly you define the word “collateral.” Ponzi schemes, for example, are multi-pledging: Assuming there’s actually some investor money available for redemptions, it’s de facto pledged many, many times over.

In Market Financial Solutions’ case, the issue’s made immeasurably worse by the fact that property lending’s generally over-collateralized. Here, according to the allegations of two creditors, both of which have links to the firm’s founder, the value of the collateral backing $1.6 billion of loans is — and try not to laugh — a little over $300 million. Overall, Market Financial Solutions’ loan book is $3.4 billion. I’ll let readers do the extrapolation.

Available reporting late Friday suggested Barclays’ exposure was around $800 million, Jefferies about $130 million. The Apollo unit said it’s in hot pursuit of recovery, partial or otherwise, on some $540 million of exposure.

On some level, it’s incredible that firms like Barclays, Jefferies and Apollo can be victimized (in Jefferies’ case repeatedly) by fraud based on something as simple as multi-pledging which, forgive me, isn’t especially difficult to spot if you’re looking.

Dimon, and this brings us full circle, said this week that, “I see a couple of people doing some dumb things to create NII.” That’s another way of saying his peers (and “peers” is a misnomer, considering Dimon has none, or at least none living) are taking too much risk in pursuit of spread.

Of course, the irony in all of this is that fractional reserve banking is itself an implicit bet on multi-pledging. A fraud we all countenance for the sake of economic vibrancy.
