Japan Swings to First Current-Account Deficit in 17 Months as Oil Costs, Foreign Payouts Bite

June deficit sharply misses forecasts, but record first-half surplus shows AI-driven exports and overseas investment income continue to underpin Japan’s external finances

Japan recorded its first current-account deficit in 17 months in June as larger dividend payments to foreign investors and higher oil import costs eroded the country’s external surplus, although a record first-half surplus underscored the continuing strength of its overseas investment income and technology exports.

The current-account balance was a deficit of 92.3 billion yen ($584.5 million) in June, Finance Ministry data showed on Monday. The result was a sharp reversal from a surplus of 1.28 trillion yen a year earlier and fell far short of economists’ median forecast for a surplus of 1.51 trillion yen in a Reuters poll.

The monthly deficit is notable because Japan has relied on income from its vast overseas investment holdings to offset periods of weak trade performance. June’s figures show how quickly that cushion can narrow when payments to foreign investors rise and energy costs increase.

The primary-income balance, which captures earnings from overseas securities and direct investment, fell 74% to 380 billion yen. It is normally the single largest contributor to Japan’s current-account surplus. The decline was driven largely by larger dividend payments by Japanese companies to foreign investors following increased investment in Japan’s domestic markets. The development illustrates an important shift in Japan’s external accounts: stronger foreign participation in Japanese equities and businesses can support asset prices and corporate financing while simultaneously increasing the income that flows out of the country.

Higher oil import costs added to the pressure. Japan remains heavily dependent on imported energy, making its trade balance particularly sensitive to movements in global crude prices. Rising oil costs pushed the country into a trade deficit in June and helped drag the overall current account below zero.

The June result, however, needs to be viewed against a much stronger performance over the first half of the year. Japan’s current-account surplus increased 22.5% to a record 17.4 trillion yen in the six months through June. The improvement was supported by a trade surplus, with exports of semiconductors destined for artificial-intelligence data centers providing a significant boost.

The contrast between the June deficit and the record first-half surplus highlights the changing structure of Japan’s external finances. The country is no longer dependent solely on merchandise trade to generate foreign currency. Investment income from overseas assets has become a critical source of support, while Japan’s manufacturers are increasingly benefiting from the global expansion of AI infrastructure.

AI Boom Strengthens Japan’s Export Position

The strength of semiconductor-related exports is enormous because it links Japan’s external balance to one of the fastest-growing areas of global capital spending. Japanese companies occupy important positions across the semiconductor supply chain, supplying chipmaking equipment, materials and components required to manufacture advanced processors and build AI data centers. Strong demand for these products has helped support exports even as other parts of global trade have faced uncertainty.

The first-half figures suggest that the AI investment cycle is becoming an important source of external demand for Japan. If spending on data centers and advanced computing infrastructure remains strong, Japanese exporters could continue to benefit through demand for semiconductor manufacturing equipment and related technology.

At the same time, the June figures demonstrate that the export gains can be offset temporarily by movements in investment income and energy costs.

Foreign Investment Creates A Two-Way Income Flow

The sharp contraction in primary income is also a consequence of Japan’s growing integration with global capital markets.

Foreign investors have increased their exposure to Japanese shares and companies, attracted by corporate-governance reforms, improving profitability and a shift away from years of deflation. That capital supports Japanese asset prices and can provide companies with access to international investors.

But the resulting dividends and other investment returns eventually flow back overseas. In June, those payments were large enough to materially reduce the primary-income surplus. This means a stronger foreign investment presence in Japan does not automatically translate into a larger current-account surplus. It can improve the country’s financial position in other ways while increasing the amount of income that leaves Japan.

The trade balance remains another source of volatility. Japan imports most of the energy it consumes, leaving its external accounts exposed to swings in oil and gas prices. A sustained increase in energy costs can quickly widen the import bill and reverse gains from stronger exports.

That vulnerability is relevant as geopolitical tensions continue to create uncertainty in global energy markets. A renewed oil-price surge would raise Japan’s import costs and could place additional pressure on the trade balance, especially if export growth slows.

Conversely, lower energy prices would provide an immediate benefit to the country’s external position by reducing the value of imports.

Record Surplus Offers Broader Reassurance

Despite the June deficit, the record 17.4 trillion yen first-half surplus indicates that Japan’s external position remains substantial.

The data also underline the resilience provided by the country’s huge stock of overseas assets. Japanese investors and companies have accumulated significant foreign investments over decades, generating a recurring stream of dividends and interest income that has increasingly compensated for the country’s historically weaker merchandise trade balance.

For the yen, the latest figures offer a mixed signal. A current-account surplus generally creates underlying demand for the currency, but larger outward investment-income payments and higher import costs can reduce that support. The record first-half surplus, however, suggests Japan continues to generate considerable external income even as individual monthly readings become more volatile.

The key question for markets will be whether the June deterioration proves temporary or marks the beginning of a broader weakening in Japan’s external balance. Currently, the first-half figures are arguing against the latter.
