I don't think you're wrong if the following holds true: Before the housing bubble burst, banks lent funds to countless borrowers who couldn't, ultimately, afford their mortgage payments (because the banks didn't do their due diligence when underwriting the loans). This was widespread across pretty much every bank and mortgage banker. Not sure of the actual percentage of borrowers who, when all was said and done, had no business getting a mortgage for a house or condo, but suffice it to say it was well into the double digits percentage-wise (there's much more to this than simply banks and borrowers with Wall St. playing a major role in the collapse, but just keeping things simple).

In this private credit situation the analog for the banks are these private credit funds that have raised the capital they've lent from institutions and high-net-worth individuals (as opposed to banks, which have funds from consumer deposits). The analog to the individual mortgage borrowers from 2008 are actual companies.

To connect the dots, if the private credit funds were like the banks pre-2008, where due diligence was an afterthought, then this could turn out to be similar. So the real question is: are the borrowers (businesses in this case) swimming naked? Or do you believe the private credit funds when they say they actually conducted a good amount of due diligence when extending their loans? Once you know the percent of the companies that are naked you can evaluate whether this could/would end up similar to 2008. Nobody knows that yet, even, I suspect, the private credit funds themselves.
