Regional Card Scheme

A regional card scheme is a payment card network whose cards are issued and accepted mainly across a group of countries, usually linked by geography, a shared currency or an economic union. It sits between a domestic card scheme, which serves a single country, and the international networks, which operate worldwide. Like other card schemes, it sets the rules, brand and technical standards that let a card issued by one member bank be used at a merchant served by another.

Regional schemes exist because governments, central banks and banks want card payments within their region to be processed, priced and governed locally, without depending entirely on global networks. They often take the form of an interbank organisation owned by member banks, sometimes with central bank sponsorship. The term is used loosely, and some arrangements described as regional schemes are really links between national schemes rather than a single brand.

Most regional schemes follow the four-party card model. Member banks issue cards to their customers and acquire card payments from merchants, while the scheme operates a central switch that routes authorisation messages between them, runs clearing and arranges settlement between members. The scheme sets the interchange fee paid between acquirer and issuer, its own scheme fees, the dispute rules and the security requirements for cards and terminals.

Because members operate in several countries, regional schemes must handle issues that domestic schemes avoid, such as multiple currencies, different consumer protection laws and differing anti-money laundering regimes. Where the region shares a currency, as in a monetary union, settlement can run in that currency through the regional central bank's payment system.

Regional card cooperation has taken several forms:

• Monetary union schemes. In the West African Economic and Monetary Union, the interbank organisation GIM-UEMOA runs a card network and switch shared by banks across member states, settling in the common currency.
• Linked national schemes. Some regions connect existing domestic schemes so that cards from one country work in another. The ASEAN Payment Network is a framework of this kind, linking national switches in South-East Asia.
• Proposed European schemes. The European Union has repeatedly discussed a pan-European card scheme to reduce reliance on non-European networks. Earlier projects, such as the bank-led Monnet initiative, were abandoned, and later efforts have moved towards account-based wallets rather than cards.

Global networks such as UnionPay, JCB and RuPay began as domestic or regional brands before expanding acceptance internationally, so the boundary between regional and international schemes can shift over time.

Supporters point to several advantages. Processing transactions within the region keeps payment data and settlement under local oversight, which central banks see as a matter of resilience and sovereignty. Fees can be set to suit local merchants and banks, often below those of global networks. Regional schemes can also extend card acceptance and financial inclusion by supporting low-cost cards for local use, and they reduce the cost of cross-border card payments within the region compared with routing them through global networks.

Many regional and domestic schemes are issued alongside an international brand on a co-badged card, so that the regional network handles local payments while the global network covers travel and online purchases abroad.

Regional schemes face strong network effects. Merchants accept cards that customers carry, and customers carry cards that merchants accept, so a new scheme struggles to gain scale against established global brands. Building online acceptance, tokenisation, wallet support and fraud tools requires heavy investment that may be hard to justify on regional volumes. Governance can also be difficult when members come from countries with different priorities and regulators.

Regulation shapes the outcome. Rules on co-badging and routing, such as those in the European Union's interchange fee regulation, which also caps fees on regulated cards, can give smaller schemes a route into wallets and terminals. Without such rules, issuers often find it simpler to issue only global brands. The rise of instant account-to-account payments has also given regions an alternative to building new card schemes, and several now favour real-time payment systems with linked mobile apps.

Domestic schemes typically benefit from a single regulator, currency and legal system, which makes them easier to run. International card networks offer global acceptance and technology but charge fees and set rules from outside the region. Regional schemes try to combine local control with wider reach than a single country can provide, and their success depends on how much member banks and merchants commit to using them.
