We developed an analytical model to study the optimal design of a new retail payment system in terms of settlement speed and system capability under both bank and fintech firm heterogeneous participation incentives. We found that three types of payment systems emerge as equilibrium outcomes: batch retail (BR), expedited retail (ER), and real-time retail (RR) payment systems. Although the base value of the payment service positively affects both settlement speed and system capability, the expected liquidity cost negatively impacts settlement speed, and total transaction volume and technological effectiveness positively impact system capability. We identified three leadership strategies to maximize social welfare: the government mandate (GM) strategy, the fintech-inclusive (FI) strategy, and the fintech-exclusive and bank-exclusive (FE+BE) strategy. When the base value of the payment service is either low or high, the GM strategy leads to a socially optimal unified system. When the base value of the payment service is in the intermediate range, and if fi…
