Buy now, pay later arrived at checkout pages with a pitch that sounded almost too simple: split a purchase into a handful of installments, charge the merchant rather than the customer for the privilege, and skip the friction of a traditional credit application. For a first wave of shoppers and merchants, it worked exactly as advertised. The harder questions — about who ends up overextended, and who absorbs the loss when they do — were always going to arrive later. They're arriving now.
The initial regulatory response to BNPL focused mostly on disclosure: making sure shoppers understood they were taking on debt, not simply choosing a payment method, and that late fees and reporting practices were transparent. Most providers adapted to that first round of scrutiny without much difficulty, because disclosure rules don't change the underlying economics of the product. What's changing now is something closer to the core of the business — how these firms assess and price the risk that a borrower won't pay.
The underwriting problem
Traditional lenders built their risk models over decades, using credit histories, income verification, and default data spanning multiple economic cycles. BNPL providers, by design, skip most of that friction — that's the entire value proposition. The tradeoff is a thinner picture of any individual borrower's ability to repay, especially for shoppers using several BNPL providers at once, a pattern that's invisible to any single lender because these loans generally don't appear on standard credit reports the way a credit card balance does.
That invisibility was manageable when BNPL represented a small slice of consumer spending and loan sizes were modest. It becomes a much bigger problem as adoption grows and providers push into larger purchase categories, where a missed payment represents real money rather than a rounding error. Underwriting models built for four small installments on a low-cost item don't necessarily hold up when applied to bigger-ticket purchases financed the same way.
The value proposition and the risk are the same thing: skip the friction of a credit check, and you also skip the picture of what the borrower can actually afford.
Regulators are catching up on data, not just disclosure
The next phase of regulatory attention is less about whether shoppers understand the product and more about whether the industry's data infrastructure can support it responsibly. Efforts to bring BNPL activity into standard credit reporting are gaining traction in multiple markets, which would solve the multi-provider blind spot but also make BNPL debt visible in ways that could affect borrowers' broader credit access — a tradeoff providers have been in no hurry to embrace.
There's a real tension here between the interests of providers, who benefit from remaining outside traditional credit infrastructure, and the interests of the financial system more broadly, which needs an accurate picture of aggregate household debt to function. How that tension resolves will shape not just BNPL but the next generation of alternative lending products built on the same "skip the friction" premise.
What happens in a downturn
BNPL has never been tested by a sustained period of rising unemployment or falling real incomes at scale. Its growth has occurred almost entirely in conditions where consumers, even stretched ones, could generally keep up with small installment payments. The real test of the underwriting model — and of the merchants and capital markets that depend on these loans performing as expected — will come whenever that condition stops holding. Providers that have spent this period building genuine risk infrastructure rather than simply scaling originations will be the ones left standing when it does.
