Two years after the Consumer Financial Protection Bureau's interpretive rule reclassified pay-in-four products as credit card-like instruments under Regulation Z, and roughly eighteen months after the UK's Financial Conduct Authority pulled BNPL inside its formal perimeter, the buy-now-pay-later category looks structurally different from the gold-rush vintage of 2021-2023. The headline names are still on checkout pages. The economics underneath have changed enough that merchants are running materially different conversations with these providers than they were two budget cycles ago.

The shorthand version: the regulatory pivot didn't kill BNPL. It killed the version of BNPL that treated underwriting as a marketing expense.

The survivors built actual credit infrastructure

Klarna, Affirm, and to a lesser extent Afterpay (now functionally a Block product line) made it through the tightening because they had, or quickly built, the things regulators wanted: disclosures that look like credit disclosures, dispute mechanisms that look like card dispute mechanisms, and underwriting that doesn't collapse the moment a household takes on three concurrent installment plans across three apps.

Klarna's IPO finally landing in early 2025 — after the well-documented delays through the rate cycle — gave the market a clean look at the post-pivot economics. Loss rates normalized, take rates from merchants stayed in the 3-6% band depending on tenor and risk band, and the "we are a marketing channel" narrative quietly got reframed as "we are a regulated credit product that also does conversion." Both can be true. Operators we spoke to are clear that the conversion lift is real on baskets above roughly €150-200 in apparel and home, and roughly $300-400 in electronics. Below that, the math gets harder to defend once you load in the MDR.

Affirm, which never leaned as heavily on pay-in-four and always carried longer-tenor product, came through the pivot with relatively less retooling. The Shopify integration remains a moat. The merchant-side complaint we hear most often is the same one we heard pre-pivot: the longer-tenor APR-bearing loans convert beautifully for big-ticket categories, but the merchant pays for the privilege.

Who pivoted, and into what

The more interesting story is the mid-tier. Several Series B/C BNPL specialists that raised in 2021 at frothy multiples have spent the last 18 months repositioning as embedded-credit infrastructure for verticals — auto repair, dental, veterinary, home services — where the lender is invisible and the merchant integration is what's sold. This is a sensible pivot. It moves them away from the head-to-head MDR fight at apparel checkout and into categories where the alternative is a 24% store card or no financing at all.

A payments lead at a mid-market specialty retailer described the shift to us in flat terms: "The 2022 pitch was 'we'll lift your conversion 20%.' The 2026 pitch is 'we'll keep your finance offer compliant and we'll co-brand a card with you.' That's a different product."

European players that built around the old, lighter-touch regime — particularly the German and Nordic specialists — have had a harder pivot. The FCA's regime, plus the parallel work coming out of the European Commission on consumer credit, raised the fixed compliance cost per loan to a level that punishes smaller books. We've watched at least three named providers quietly stop accepting new merchants in the UK in late 2025, which is the polite version of exit.

Who quietly shrank

The category that lost the most ground is the white-label BNPL stack — the firms that sold "your own BNPL, your own brand" to retailers in 2022. Almost none of those programs survived contact with the new disclosure regime. The retailers that launched them either folded the program back into a co-brand card partnership with a bank, or shut it down and routed volume back to Klarna or Affirm.

A few specifics worth tracking:

• Pay-in-four as a standalone product is shrinking as a share of BNPL volume. Longer-tenor, interest-bearing loans are taking share. This is what the regulators wanted.
• Merchant take rates have not collapsed. The "race to zero MDR" narrative from 2023 didn't happen. If anything, the surviving providers have firmer pricing because the field is thinner.
• Returns and disputes are the live operational pain point. The CFPB rule pulling pay-in-four under Reg Z means merchants now field chargeback-adjacent disputes routed through the BNPL provider. Several operators flagged this as the integration work they underestimated.

What this means for merchants in the back half of 2026

If you signed your BNPL contract in 2022 or 2023, it's worth a re-paper. The economics the providers are willing to offer in 2026 are different, and not always worse — the survivors want category coverage and are willing to negotiate on tenor mix and exclusivity windows in exchange for it. A CFO at a mid-market home goods retailer told us they re-cut their Klarna deal in Q1 and moved roughly 80 basis points off blended MDR by agreeing to a longer exclusivity on the longer-tenor product. That's real money on a category running 6-9% operating margins.

The other lesson is harder to action: BNPL is now boring. That's a compliment. It means it can be evaluated like any other payment method — on MDR, conversion lift, dispute load, and integration cost — without the surrounding noise about whether the category exists. It exists. It's regulated. Price it accordingly.
