The current account surplus in the April to September period more than quadrupled from a year earlier, the government said Tuesday. There was a notable gain in the travel surplus in addition to a fall in the value of imports due to cheaper crude oil.

The surplus of ¥8.69 trillion, a 4.3-fold increase from the previous year, was also boosted by increased overseas income on the back of a weaker yen.

The current account balance is one of the widest gauges of international trade.
