India's G20 Presidency vision for 2023 prioritizes "Accelerated, Inclusive, and Resilient Growth." Integrating micro, small, and medium enterprises (MSMEs) into global trade aligns with this goal as they contribute nearly 30% to India's GDP. However, credit scarcity hinders MSME growth globally, especially in developing nations where timely credit is challenging. Digital Public Infrastructure (DPI) is transforming this scenario. Initiatives like the Open Credit Enablement Network (OCEN) 4.0 and the Account Aggregator Framework facilitate cash-flow-based lending and responsible data sharing, easing MSMEs' credit access. A UNDP report suggests that open-source DPI can bridge 50% of the credit gap for MSMEs, benefiting millions. DPI helps by maintaining financial records, enhancing transparency in credit markets, and introducing innovative credit mechanisms. Optimizing DPI can boost India's MSME sector and improve national development.
