Informality and digital payments' trade-offs

Between 2019 and 2023, the number of electronic transactions tripled in six Latin American economies. The share of adults using digital wallets, mobile money, and mobile bank accounts went from 3% in 2011 to 40% by 2021. A region that not long ago was defined by financial disasters, hyperinflation, and deep mistrust of banks has become one of the world's leading examples of how digital payments can transform an economy.

Diego Vera-Cossio edited Beyond Cash, The Digital Payments Revolution in Latin America and the Caribbean, the Inter-American Development Bank's new regional microeconomic report on digital payments. He tells Tim Phillips how the effects of this revolution are more profound that freeing people from the need to carry cash. In Santiago, bus robberies fell when drivers stopped handling cash. In Brazil, firms in the most cash-intensive sectors grew substantially after the instant payment system Pix launched. In Colombia, people without any credit history started borrowing formally after being nudged to receive their social program payments digitally. And in Bolivia, where 80% of the workforce is informal, people are scanning QR codes at street market stalls. 

The question Diego, his colleagues, and policymakers int he region and beyond, are now trying to answer is how to build on all of that, and how to make it stick.
