Japan's current account surplus expanded for the fifth straight month in May, rising 31.1% from a year earlier, the Finance Ministry said Wednesday, auguring well for economic growth in the second quarter.
The surplus in the current account, the broadest measure of Japan's trade with the rest of the world, stood at 2.134 trillion yen (US$17.53 billion) in May before seasonal adjustment, the data showed.
That topped the 19.8% expansion forecast by economists surveyed by Dow Jones and Nikkei.
The surplus jumped 50.3% from a year earlier in April.
The current account measures trade in goods, services, tourism and investment. It is calculated by determining the difference between Japan's income from foreign sources against payments on foreign obligations and excludes net capital investment.
