Japan's current account surplus jumped 88.0 percent in April from a year earlier, providing fresh evidence that robust growth in exports is helping the economy recover from a deep slump, Finance Ministry data showed Tuesday.

The current account balance — the broadest gauge of trade in goods and services — logged a surplus of ¥1.2421 trillion, staying in the black for the 15th consecutive month, the ministry said in a preliminary report.

The balance of trade in goods and services posted a surplus of ¥433.6 billion compared with a deficit of ¥260.9 billion a year before.
