“Several companies have determined that the biggest opportunity to prove their worth is in the decidedly boring race to help emigres handle remittances, a global market expected to total $550 billion this year, according to the World Bank. The average fee on remittances is 9 percent of the transaction cost, and some banks charge additional ‘lifting’ fees of up to 5 percent when someone wants to turn the remittance into cash. Sitting in the middle of money transmissions is a lucrative business. Western Union(WU) brought in $4.6 billion in transaction fees charged to consumers last year and almost $1 billion further in foreign-exchange revenue from its consumer business.”
