The amount of money sent home by Mexican migrants living abroad surged in March by 15.1 percent versus a year ago, central bank data showed on Tuesday.
Remittances to Mexico totaled $2.52 billion last month, compared with $2.189 billion in March last year. In February, the figure was $2.057 billion.
U.S. President Donald Trump ran an election campaign heavy on anti-Mexican rhetoric and threatened to halt transfers from Mexican nationals unless Mexico agreed to pay for a wall he wants built on the U.S. southern border to keep out illegal immigrants.
Mexico has said it will defend the free flow of remittances.
Remittances to Mexico totaled $26.97 billion in 2016, up nearly 9 percent from 2015, and the highest ever according to Mexican central bank figures dating to 1995.
