The IMF published a paper that reviews how rapid digital payment adoption in ASEAN—especially Thailand’s PromptPay-led fast payments and QR linkages—is reshaping domestic and cross-border transactions by lowering costs, boosting financial inclusion, and supporting SMEs, while introducing new cyber, fraud, and AML risks. It documents a surge in domestic fast and QR payments, the build‑out of bilateral QR and fund-transfer linkages under ASEAN’s Regional Payment Connectivity and Local Currency Transaction frameworks, and emerging multilateral architectures such as BIS’s Project Nexus and wholesale CBDC platform mBridge to overcome the limits of fragmented bilateral models. Using Thai data for 2020–24, the empirical analysis finds that cross‑border QR usage rises when local‑currency–USD volatility is higher, suggesting local‑currency QR payments help users manage FX risk compared with card payments settled via the dollar, and that QR tends to substitute for traditional bank and card channels where financial access is weaker. The authors argue that scaling interoperable, local‑currency cross‑border QR schemes—alongside better data use for SME credit, stronger regional AML/CFT coordination, and harmonized data protection—can deepen ASEAN trade integration and strengthen financial resilience to external shocks.
