Point-of-sale instalment lending Market Outlook 2026–2033: Growth Drivers, Key Companies, Strategic Developments & Adoption Forecast — A Meticulous Next™ Foresight Brief

This Meticulous Next™ brief examines buy now pay later, where a shopper splits a purchase into fixed instalments at checkout, often without interest, and the merchant pays the fee. It tests how far point-of-sale instalment lending becomes a regulated, mainstream form of consumer credit by 2033, and what that means for fintech lenders, banks, card networks, merchants and regulators.

The Financial Conduct Authority started regulating deferred payment credit in the United Kingdom on 15 July 2026, bringing about 11 million users under rules on affordability checks, clear information, support for customers in difficulty and access to the Financial Ombudsman Service. The conclusion is that the product moves from an unregulated convenience to a regulated form of credit, and lenders must carry the cost of authorisation and compliance.

The UK market is large. The Financial Lives Survey found that 20% of UK adults, or 10.9 million people, used buy now pay later in the 12 months to May 2024, and the market grew from GBP 0.06 billion in 2017 to over GBP 13 billion in 2024, according to the regulator. The conclusion is that regulation arrives after the product has reached a large part of the adult population, so rules affect an established business rather than a new one.

Growth continues at leading lenders. Affirm reported fiscal first quarter 2027 gross merchandise volume of USD 14.4 billion, up 34%, and revenue of USD 1.26 billion, up 35%, with a 30-day delinquency rate of 2.9% excluding Peloton, up 35 basis points from the previous quarter. The conclusion is that credit performance becomes the test for lenders as volume scales.

The brief treats buy now pay later as an accelerating signal with a seven year horizon to 2033. It identifies which lenders, banks and merchants move first and what each means for credit, regulation and checkout. It is a focused 105-page decision brief that presents an indicative trajectory rather than a segmented market model.

A point-of-sale instalment loan starts with a checkout offer, a decision within seconds and a repayment schedule of fixed payments. The lender pays the merchant at once, less a fee, and collects from the shopper over time. Affirm reported that its card product reached USD 3.3 billion of volume in the quarter, up 117% and 23% of its total volume. The conclusion is that instalment credit is moving from the merchant checkout to a general payment card, and the line between instalment credit and card credit is narrowing.

Rules set what a lender must do before it lends. Under the FCA regime, lenders must run proportionate affordability checks, give clear information on payment dates, amounts and the effect of missed payments, support customers in financial difficulty and give access to the Financial Ombudsman Service. Agreements entered into before 15 July 2026 remain outside the rules, and merchants that offer their own credit stay exempt. The conclusion is that existing books run off outside the rules while new lending follows them, so the cost of compliance applies to new volume first.

Authorisation shapes who can lend. Firms could register for a temporary permissions regime between 15 May and 1 July 2026, and then have six months to apply for full authorisation. Fifteen firms had registered by the close, including Clearpay. The conclusion is that large lenders keep operating during the transition, while smaller entrants must complete authorisation before they can continue to grow.

Credit quality is the main commercial test. Affirm reported an allowance for credit losses of 6.3% of loans held for investment, up from 5.9%, with provision for credit losses up 59%. The conclusion is that lenders must reserve more as volume grows, and funding cost and loss rates decide which providers keep their margin.

The limits are the cost of funding and credit losses, scrutiny of consumer debt and affordability, and the pace of regulatory change across countries. The brief tests each limit against the cost trajectory to 2033.

The point-of-sale instalment lending market, covering pay-in-four and longer-term instalment loans offered at merchants and online checkouts, card-linked instalments, and credit data and decisioning services, measured by provider revenue from merchant fees, interest and fees, and excluding credit card instalment plans, merchant own credit and personal loans, is valued at USD 14.0–18.0 billion in 2026 and is projected to reach USD 35.03–45.04 billion by 2033, at a CAGR of 14%.

The 2026 base rests on pay-in-four and longer-term instalment loans, card-linked instalments, and credit data and decisioning services provided in North America, Europe, Asia-Pacific and Latin America. Growth then follows the volume originated, the merchant fee per transaction and the interest earned on longer-term loans.

The forecast is sensitive to regulation in new markets, credit losses in a weaker economy and the extent to which banks and card networks take share at checkout.

The base case assumes UK rules bed in without a break in lending and other markets follow with similar rules, bringing the inflection to about 2028 and a 2033 value near the middle of the range. An accelerated case assumes quick authorisation and wide bank entry, bringing the inflection to 2027 and lifting the 2033 value to the top of the range. A delayed case assumes rising credit losses and stricter affordability rules, moving the inflection to 2031 and holding growth at the bottom of the range.

Where value migrates.

In 2026 value sits with fintech lenders that run pay-in-four at large retailers and with merchants that gain conversion from it. By 2028 it moves toward lenders that clear authorisation, report to credit bureaus and fund loans at low cost, and toward banks and card networks that bring instalments to checkout. By 2033 it settles with instalment credit as a standard checkout option, where merchant networks, funding cost and credit performance carry the margin. Margins hold for lenders with low losses and cheap funding, and narrow for lenders that grow volume faster than their credit controls.

UK regulation from July 2026 for about 11 million users, growth of 34% in volume at a leading lender and bank entry support growth, while rising credit reserves, affordability scrutiny and differences in national rules hold back the pace.

Rising credit losses, stricter affordability rules and slow authorisation could slow progress. The brief therefore tracks four indicators: volume and delinquency at leading lenders, firms authorised under the UK regime, share of checkouts offering instalments and bank and card network launches.

Pay-in-four at large retailers first, then bank-issued instalments and regulated credit at scale, then standard checkout option status is the expected order of change.
