Japan's current account surplus climbed to a record ¥4.7 trillion ($29.8 billion) in March, marking a 29.1% increase from the same month a year earlier, the Finance Ministry reported on Wednesday.
The underlying trade balance strengthened markedly, with the trade surplus expanding 35.9% year-on-year in March. The ministry's balance of payments data pointed to exports of semiconductors and other electronic components as a primary contributor to that improvement.
In addition to the trade gain, direct investment income added to the income-side surplus, according to the report. Together, these elements lifted the overall current account result for the month.
On a seasonally adjusted basis, the current account surplus increased from the prior reading but remained below the level recorded in September, which the ministry said was the highest since records began in 1996.
The March performance reflected robust global demand for products tied to artificial intelligence applications, and a weaker yen provided additional support to the domestic economy over recent months, the report noted.
However, the Finance Ministry cautioned that the recent rise in oil prices presents a headwind that is expected to reduce the surplus in coming months. Japan's substantial dependence on imported natural resources makes the economy particularly exposed to disruptions in oil and gas supplies, and the report highlighted the potential vulnerability stemming from the conflict in the Middle East.
While the March figures underscore strength in export-oriented sectors such as semiconductors and electronics, the ministry's data also make clear that external energy cost pressures could erode those gains going forward. The report did not provide projections beyond noting the expectation that higher oil costs will weigh on the surplus in the near term.
Overall, the March balance-of-payments release presents a mixed picture: a record headline surplus supported by trade and investment income, tempered by external energy price risks and resource-supply vulnerabilities.
