Remittances are the money that migrant workers send to their families in their countries of origin, usually in small, regular amounts that pay for food, rent, school fees and health care. IFAD estimates that about 220 million migrants and diaspora members support 1.1 billion relatives, and that recorded flows to low- and middle-income countries reached US$728.6 billion in 2025, more than four times global official development assistance. Every transfer carries a fee and, often less visibly, a margin on the exchange rate. The World Bank tracks these prices quarterly: in the third quarter of 2025, sending the equivalent of US$200 cost 6.36% of the amount on average, more than twice the 3% that the Sustainable Development Goals set for 2030.
The burden is uneven. Sending money to Sub-Saharan Africa cost 8.46% on average, the highest of any region, and 13 corridors still charged more than 20%, nine of them in that region. Transfers paid out or funded in cash, and those sent through banks, cost far more than digital services. For households where remittances are a main source of income, and for countries where they make up a large share of the economy, such as Tajikistan, Tonga and Nicaragua, these costs reduce money that would otherwise go to basic needs. High prices and strict account-opening rules can also push migrants towards informal channels that offer no consumer protection.
