Will 'buy now, pay later' push cash-strapped holiday shoppers too far?

Consumers spend more with BNPL

BPNL credit burst onto the market within the past several years, advertised under fintech providers like Klarna and Afterpay and tied to the point-of-purchase of a particular product.

Paying with BNPL differs from credit cards. Rather than a revolving credit line, consumers take out an installment loan through the retailer at the time of purchase, usually agreeing to pay the total in four installments. There’s typically little or no credit check and most loans charge zero interest if the bills are paid on time.

Retailers are willing to pay more for providing the service because almost half of consumers spend between 10 percent to 40 percent more when paying through BNPL versus a credit card, the authors note, citing a December 2020 survey from data firm Cardify.

Why do consumers use BNPL?

The majority of consumers who use BNPL have credit cards, but use the installment financing because it offers more favorable terms.

Detailed consumer data for BNPL hasn’t been easy to analyze previously because transactions aren’t reported publicly or to credit bureaus. To track BNPL use, researchers tapped data from a US aggregator for 10 million individual transactions from January 2010 to May 2021 among merchants, providers, and consumer bank accounts.

The authors then analyzed a sample of 400,000 consumers, half who used BNPL and half who didn’t. A separate dataset from Builtwith.com helped the researchers track some 20,000 specific retailers to identify merchants using BNPL, including the top US retailers.

Penalizing lower-income consumers

The loans create what the authors call the “flypaper effect.” Consumers with healthy access to liquidity like credit cards or bank accounts spend a bigger portion of their total budget on retail goods when they use BNPL. Higher-income users are more likely to use BNPL for big-ticket items like household appliances, the researchers note.

Lower-income consumers, those who may not use or have access to a credit card, not only spend more on retail but their total spending increases, which makes them more likely to incur overdraft fees and drain their savings accounts, the researchers write. Consumers earning $25,000 to $45,000 a year use BNPL more on average than other groups—and 20 percent incur overdraft fees and 17 percent pay low-balance fees, the authors found.

“Across all users—those who use credit cards, non-credit card users, everybody—the retail share of expenditures go up,” says Williams, an assistant professor in the Finance Unit. “But the increase in total spending is only coming from non-credit card users. And it is only these users that are incurring the overdraft fees and low [savings] balances.”

Growth in BNPL—whose providers don’t face the strict financial regulations that banks do—drew the attention of the Consumer Financial Protection Bureau earlier this year. Fintech firms like Affirm, Quadpay, and Sezzle aren’t subject to the US Truth in Lending Act, so installment transactions don’t impact credit scores.

This means that consumers who use such services might have more debt than is apparent, which may be a concern for traditional lenders, like banks, the authors note.

How risky is the shopping method?

BNPL can keep consumers—particularly those who lack access to traditional credit—from seeing the full picture of their spending during the heady holiday shopping season, Williams says. For example, if a shopper initially spends $25 for a $100 sweater, they might feel as if they're getting a bargain, Williams notes.

“But over the next two-week intervals—at two weeks, at four weeks, at six weeks—$25 is coming out of my account automatically," Williams says. "I forget about these $25 payments in a way that they're related to the sweater. And then it's 'Oh, my goodness, money's coming out of my account.'"

Consumers who make multiple purchases may be served by different fintech providers, which may be harder to track than credit cards that come with a list of purchases on a statement. Some buyers end up paying BNPL bills with savings or other forms of credit, the authors write.

What’s more, inflation is curbing spending habits just as the number of defaults on BNPL loans creep higher. Add in a potential recession and the authors question whether the model might prove to be riskier for consumers, investors, and retailers in the future.

“The product was very popular [during the pandemic] because people were stuck at home. People were shopping, flush with cash. It feels like somebody is giving you free money. Why should that be bad, right? Especially if the alternative is paying 20 percent in interest on your credit card,” Di Maggio says. Now, however, “the existing portfolio of these products is likely to be highly risky.”
