The current account surplus expanded to ¥2.38 trillion ($21 billion) in August — the highest on record for the month — lifted by foreign investments and a bigger trade surplus, government data showed Tuesday.
The surplus in the primary income account, which reflects how much Japan earns from foreign investments, rose 13.0 percent from the year before to ¥2.24 trillion, the Finance Ministry said in a preliminary report.
The current account logged a surplus for the 38th straight month in August. The yen's depreciation against the dollar was one key factor boosting income from foreign investment, a ministry official said.
