This chapter reviews the evidence demonstrating the ways in which financial inclusion can help adults in extreme weather-vulnerable countries build resilience using formal financial services, such as digital payments, savings, credit, and insurance. Achieving these benefits requires public investment in connectivity, however. A strong regulatory framework is also necessary to protect against the risks to consumers, such as fraud and phishing scams targeting accounts, over-indebtedness in digital credit, and customers receiving incomplete or incorrect information on the fees and costs of financial products.
