The promise was simple: split your purchases into four easy payments, interest-free. But as Buy Now Pay Later (BNPL) services have exploded in popularity, a troubling picture is emerging of Americans layering invisible debt that traditional credit systems can't see—and the potential consequences are keeping regulators up at night.

Measured by gross merchandise volume, the global BNPL market has reached approximately $560 billion in 2025, reflecting 13.7% year-over-year growth. Industry revenues are projected to climb from $23.37 billion to $28.44 billion in 2026. But beneath these impressive growth figures lies a complex web of consumer debt that operates largely outside the traditional financial system.

The Phantom Debt Problem

Unlike credit cards, mortgages, or auto loans, most BNPL loans are not reported to credit bureaus. This creates what regulators call "phantom debt"—borrowing that other lenders simply cannot see when evaluating a consumer's creditworthiness.

Consider this scenario: A consumer takes out BNPL loans across five different platforms—Klarna, Afterpay, Affirm, PayPal Pay Later, and Apple Pay Later. A traditional lender checking that consumer's credit report would see none of these obligations. The credit system is, in effect, flying blind.

Who's Using BNPL—And Who's Getting Hurt

Research from the Kansas City Federal Reserve reveals a troubling pattern: BNPL users tend to be more financially vulnerable relative to non-users. They are typically younger and less educated, with higher debt burdens and lower credit scores.

The data shows that around 34-41% of BNPL users miss payments—a stark contrast to the interest-free, seamless experience marketed by providers. And nearly one in five BNPL users are "layering debt," using credit cards to fund their BNPL payments in a potentially dangerous cycle.

The Financial Profile of BNPL Users

  • Younger demographic (primarily Millennials and Gen Z)
  • Lower average credit scores
  • Higher existing debt-to-income ratios
  • More likely to carry revolving credit card balances
  • More likely to have experienced recent financial distress

The Holiday Hangover

The 2025 holiday season saw record BNPL usage, with consumers splitting everything from electronics to everyday purchases into installment plans. But as those bills come due in early 2026, the ripple effects are becoming apparent.

According to recent research, much of the nominal growth in holiday spending was fueled by BNPL services. The concern is that what appeared to be robust consumer demand was actually debt-financed spending that will constrain consumption in the months ahead.

LendingTree data shows that average holiday debt reached $1,223 in 2025—the highest figure since 2022 and up from $1,181 the prior year.

The Spillover Effect

Perhaps most concerning to economists is what happens when BNPL borrowers face financial stress. Because BNPL loans are typically smaller than other debts, borrowers tend to prioritize keeping them current. This means larger obligations—credit cards, auto loans, even mortgages—may start to default first.

The Federal Reserve Bank of Richmond has warned specifically about BNPL's potential systemic risk through these "spillover effects onto other consumer credit products." A cascade of defaults in traditional credit products, triggered by invisible BNPL overextension, represents a scenario regulators are actively monitoring.

Regulatory Response Taking Shape

Global regulators have begun treating BNPL as "credit in disguise," implementing new rules to curb hidden debt and underreported obligations:

  • United Kingdom: The FCA has confirmed BNPL will come under full regulation by July 2026, bringing the £28 billion sector's 23 million users under consumer credit protections
  • Australia: Treasury confirmed BNPL will fall under the National Consumer Credit Protection Act by 2026
  • United States: Regulators are moving toward requiring BNPL providers to report loans to credit bureaus and subjecting them to Truth in Lending Act disclosures

The Current Situation—Not a Crisis Yet

It's important to note that BNPL has not yet triggered a consumer debt crisis. Delinquency rates across consumer credit products remain manageable, and charge-offs have not spiked dramatically. But the combination of factors—phantom debt, rising unemployment in some sectors, and the end of various pandemic-era protections—creates conditions where problems could accelerate quickly.

What Consumers Should Consider

For those using or considering BNPL services, several considerations are worth keeping in mind:

Track All Obligations

Because BNPL loans may not appear on your credit report, maintaining your own record of all outstanding payments is essential. A spreadsheet tracking due dates and amounts across all platforms can prevent nasty surprises.

Understand the True Cost

While BNPL is marketed as interest-free, late fees can be substantial. More importantly, the psychological effect of making purchases feel "free" can lead to overspending that wouldn't occur with traditional payment methods.

Consider Credit Building Alternatives

Since most BNPL payments don't build credit history, consumers looking to establish or improve their credit scores should consider whether a credit card with responsible usage might better serve their long-term financial goals.

The Bottom Line

Buy Now Pay Later services have fundamentally changed how Americans, particularly younger consumers, approach purchases. The convenience is undeniable, and for disciplined users who track their obligations, BNPL can be a useful financial tool.

But the sector's explosive growth has outpaced regulatory oversight, creating a shadow credit system that adds risk to both individual households and the broader financial system. As 2026 unfolds, the true cost of the BNPL boom may become clearer—and for some consumers, that reckoning could be painful.
