Tuesday's data showed the U.S. goods and services trade deficit narrowed 1.2% in April to $55.9 bln as exports jumped to a record high. March's deficit was revised to $56.6 bln from $60.3 bln; economists had forecast $56.2 bln for April. If sustained, the export upswing could help trade contribute to GDP growth this quarter; trade has subtracted from GDP for two consecutive quarters.(金十数据)
