Global cross-border payments are on track to exceed US$250 trillion by 2030, but the biggest brake on that growth is no longer technology—it is the lack of interoperability, according to new industry analysis referencing the Group of 20’s 2020 Roadmap for Enhancing Cross-Border Payments. Interoperability means different payment systems, banks, and regulators can talk to each other seamlessly. Today they often cannot: rules differ by country, message formats do not match, compliance checks are duplicated, and settlement timings are out of sync. The result is friction that adds cost, delay and uncertainty to moving money across borders.
The mechanics are straightforward. A company or individual sends money from one country to another, but the payment must pass through multiple banks and market infrastructures that use different standards and legal requirements. Message formats such as the ISO 20022 standard are rolling out unevenly; anti-money laundering (AML) and Know Your Customer (KYC) checks are applied repeatedly because regulators do not recognise each other’s processes; and settlement often relies on correspondent banks holding foreign currency accounts. Even where instant domestic rails exist, cross-border transfers can stall because there is no common rulebook or shared identity framework to tie those rails together.
The timing matters because domestic payments have sped up dramatically, heightening expectations for cross-border speed and cost. The Group of 20 roadmap aims to improve cost, speed, transparency and access by 2027, but progress depends on coordination rather than new code. For South Africa, this is not abstract: BankservAfrica and the South African Reserve Bank are upgrading real-time gross settlement (RTGS) systems and exploring links to regional schemes such as the Southern African Development Community RTGS and the Pan-African Payment and Settlement System. Without compatible standards and mutually recognised compliance, South African exporters, fintech firms and remittance providers will keep shouldering reconciliation headaches and higher fees.
The direction of travel is clear but not guaranteed. Watch for concrete interoperability steps: wider ISO 20022 adoption and alignment, bilateral bridges between instant payment systems, regulatory agreements that allow shared digital identity and common KYC utilities, and pilots that connect central bank digital currency projects across borders. Uptake of the Pan-African Payment and Settlement System and the pace of the Group of 20 roadmap deliverables will be the clearest signals of whether the industry can turn faster domestic payments into genuinely faster and cheaper cross-border flows.
The immediate implication: Global cross-border payments forecast to top US$250tn by 2030, but lack of interoperability across systems, regulators and standards is now the main growth barr. Watch the next communication from PayInc (BankservAfrica) for confirmation of direction and follow-through.
