Nigerians in diaspora wired $22 billion home in 2017, making it the fifth largest remittance by immigrants in the world.
The World Bank in a report, described the figure as an African record, adding that Egypt received $20 billion from its citizens abroad.
It said payments from immigrants back to their home countries rebounded to reach a new record in 2017 but the costs of transferring funds also increased.
The stronger-than-expected recovery in remittances, payments that are key to supporting the economies of many poor countries was driven by growth in Europe, Russia and the United States, the World Bank said.
The bank estimates that officially recorded remittances to low- and middle-income countries reached $466 billion in 2017, an increase of 8.5 percent over $429 billion in 2016. They are expected to increase by about four percent this year.
Remittance inflows improved in all regions. The top remittance recipients were India with $69 billion, followed by China ($64 billion), the Philippines ($33 billion), Mexico ($31 billion), Nigeria and Egypt followed.
The global average cost of sending $200 was 7.1 percent in the first quarter of 2018, and sub-Saharan Africa remains the most expensive place to send money to, where the average cost is 9.4 percent.
“While remittances are growing, countries, institutions, and development agencies must continue to chip away at high costs of remitting so that families receive more of the money,” said Dilip Ratha, lead author of the report.
The bank called on countries to take steps to simplify the process to reduce the costs, including “introducing more efficient technology”.
By region, Europe and Central Asia saw the biggest growth last year, jumping 21 percent, while Sub-Saharan Africa rose 11 percent.
East Asia and the Pacific saw the biggest inflows of $130 billion, as South Asia received $117 billion, followed by Latin America with $80 billion.
