Global Schemes: Who Really Runs the World's Card Payments

Oct 10

4 min read

Tap your card for a flat white and, in under two seconds, a message races across a network that moved roughly $27 trillion last year. Two companies, Visa and Mastercard, run most of it.

But look closer and the map is being redrawn. From Shanghai to São Paulo to Madrid, home-grown rivals are quietly taking back their own turf. Here's who really runs the world's card payments, and who's coming for the crown.

First, what a scheme actually does

A scheme doesn't lend money or hold your balance. It sets the rules, runs the network that routes authorisations, and calculates who owes whom at settlement. It earns a small fee on every transaction from both sides. Think of it as the motorway operator, not the car.

Two models exist:

• Four-party (open loop): the scheme sits between separate issuers and acquirers. Visa, Mastercard, UnionPay.

• Three-party (closed loop): the scheme is also the issuer and the acquirer. American Express and Discover historically; Amex now also licenses banks to issue in many markets.

The global brands at a glance

Scheme	Model	Latest annual volume	Transactions	Where it's strongest
Visa	Four-party	$16.7tn total, $14.2tn payments (FY to Sep 2025)	257.5bn processed	Everywhere; dominant in the US, UK, Latin America
Mastercard	Four-party	$10.6tn gross dollar volume (2025)	175bn+ switched	Strong in Europe, Africa, the Middle East; 77% of in-person transactions contactless
UnionPay	Four-party	Largest card issuer base in the world; volume mostly domestic China	n/a publicly	China, and Chinese travellers abroad
American Express	Three-party	Roughly $1.6-1.7tn billed business (2025, estimate; $804bn in H1 alone)	n/a	Premium consumers, corporate cards, US
JCB	Mixed	Smaller global footprint	n/a	Japan and Japanese travel corridors
Discover / Diners Club	Three-party	Now owned by Capital One (deal closed 2025)	n/a	US; Capital One is moving debit volume onto it

Across the six global brands, cards generated 828.1 billion purchase transactions in 2025, up 7.1%. Visa alone held about 40.8% of them.

Country by country: who wins where

United States. Visa is the giant at home. Of the $9.99tn spent on US Visa and Mastercard cards in 2025, Visa took $7.03tn, or 70.4%. Credit cards across all four US networks hit $6.5tn.

United Kingdom. Visa dominates debit (almost every high-street bank issues Visa debit), while Mastercard is stronger in credit and with fintechs like Monzo and Revolut. Cards made up 64% of all UK payments in 2025.

Europe. Card-heavy, but sovereignty is the theme. Several countries run domestic debit schemes (girocard in Germany, Cartes Bancaires in France, Bancomat in Italy). In October 2026, Bancomat, Bizum, EPI/Wero, SIBS MB WAY and Vipps MobilePay formed the European Network for Payments, linking about 130 million users across 13 countries. It starts with P2P transfers, then e-commerce and in-store.

Asia-Pacific. The biggest region by value, with $15.5tn in card purchase volume in 2025. But that figure fell 8.2% as Chinese spending moved from cards to Alipay and WeChat Pay.

Africa. Visa and Mastercard lead on international cards, but local networks matter: Verve in Nigeria, and mobile money (M-Pesa) rather than cards in East Africa.

The domestic challengers worth knowing

Country	Domestic scheme or rail	Why it matters
China	UnionPay	The default card in the world's largest payments market
India	RuPay + UPI	RuPay credit cards can now link to UPI, India's instant rail
Brazil	Elo + Pix	Pix took 42% of Brazilian e-commerce value in 2025
Nigeria	Verve (Interswitch)	Africa's largest domestic card scheme
Saudi Arabia	mada	Runs most in-store debit spend
Russia	Mir	Became the only option after Visa and Mastercard exited in 2022
Japan	JCB	Japan's homegrown global brand
Europe	Wero / ENP	Europe's bid for an A2A alternative to the card schemes

What's changing in 2026

• Tokenisation everywhere. Visa has more than 16 billion tokens live; Mastercard says nearly 40% of its transactions are tokenised.

• Beyond cards. Both schemes now earn a fast-growing share of revenue from value-added services: fraud tools, data, open banking.

• Agentic commerce. Visa Intelligent Commerce and Mastercard Agent Pay are racing to be the rails AI shopping agents pay on.

• Stablecoin settlement. Both are piloting stablecoin settlement with banks, including a Lloyds and Visa test in the UK.

The takeaway: the schemes are still the only truly global rails. But the next billion payments are increasingly domestic, instant and account-to-account, and the schemes are reinventing themselves as network-of-networks to stay in the middle.
