This paper proposes a regulatory and operational model for the issuance of local stablecoins, aimed at enhancing financial inclusion, operational efficiency, and monetary policy effectiveness without requiring Central Bank Digital Currencies (CBDCs). Grounded in the infrastructure and regulatory oversight of the traditional financial system, the model centralizes stablecoin issuance within prudentially supervised entities, primarily banks, through tokenized deposit schemes. A dynamic reserve requirement mechanism is introduced, enabling central banks to influence credit supply via adjustments to the reserve ratio, effectively transforming stablecoins into a new monetary policy lever.
