In many low-income and transitional economies, most households and businesses do not have access to formal financial services. This “unbanked majority” therefore faces high transaction costs for payment services, can’t use cash savings services for income smoothing and asset accumulation, and does not have the option of generating additional income and investment through conventional credit services. High-income countries also have significant unbanked or underbanked populations, usually low-income households and family businesses. The primary purpose of promoting financial inclusion is to ensure equal opportunity to utilize services that are essential in managing household and enterprise finances, regardless of one’s income level or size of business. In this session we will explore how financial inclusion seeks to mitigate financial marginalization through innovations in financial product design, delivery, and regulation, thus promoting more equitable and sustainable economic growth.
