The Hidden Portfolio: Stacking, Visibility, and Denominators

A single BNPL purchase can look small, short-lived, and easy to repay. The household’s financial position may look different when several payment schedules are active, when different providers cannot see one another, or when the product is compared with a borrower’s other unsecured debt. This chapter examines the CFPB’s linked records at that portfolio level. The aim is to explain what repeated borrowing and debt-share statistics reveal, and to show where the evidence stops before a causal conclusion.

The word “hidden” needs care. It does not mean that a provider has no information about its own customer. It means that, during the period studied, most pay-in-four BNPL obligations and repayment histories were not furnished to the nationwide consumer reporting companies used by other creditors. A provider can see its own schedule while a lender making another decision sees only part of the borrower’s unsecured obligations.

One purchase becomes a portfolio

The CFPB defines simultaneous BNPL borrowing in a specific way: a consumer originated a subsequent BNPL loan within 42 days of the first, conditional on having originated at least one loan in that year. This definition gives researchers a consistent window for identifying overlapping or near-overlapping originations. It does not mean that every loan in the window had exactly the same remaining repayment period, and it is not a moral definition of excessive use.

In the matched credit-record sample, 62.7 percent of BNPL borrowers in 2022 had simultaneous loans at one or more firms at some point during the year. The share with simultaneous loans at different firms was 32.6 percent. In 2021, the corresponding figures were 62.8 percent and 31.7 percent. Viewed across the entire adult population with a credit record, 6.6 percent had simultaneous loans at any firm in 2022 and 3.5 percent had them across different firms. The borrower-level and population-level percentages use different denominators, so they answer different questions.

Cross-provider borrowing matters because the providers do not automatically share a complete view of one another’s pay-in-four obligations. A consumer may choose among the providers available at different merchants, or may seek more credit than one provider offers. The CFPB says that even BNPL firms may not observe loans at other firms, making cross-firm stacking a particular blind spot. A lender assessing a new obligation can therefore see a consumer’s conventional credit record without seeing the full set of short-term BNPL schedules.

Repeated borrowing is also more common than a single annual-use rate suggests. The average BNPL borrower originated 9.5 loans in 2022, up from 8.5 in 2021. The median rose from three loans to four. The average interval between originations was about 45 days in 2022, compared with about 42 days in 2021. These measures describe persistence and frequency, not the reason for each purchase or whether each borrower experienced harm.

The distribution is uneven.
