Japan's Yen Hits Fresh 40-Year Low as Trade Deficit Widens Despite Export Boom

Tokyo | EcoPulse24

Japan's economic outlook came under renewed pressure on Wednesday after the yen weakened beyond ¥163 per U.S. dollar - its lowest level since October 1986 - while the country's trade balance returned to deficit as record imports outpaced the strongest export growth in more than two years.

The currency's slide has heightened speculation that Japanese authorities could intervene in foreign exchange markets if volatility accelerates further, while rising oil prices and widening interest-rate differentials continue to weigh on the world's fourth-largest economy.

Official data showed Japan recorded a trade deficit of ¥406.9 billion in June, reversing from a ¥122.3 billion surplus a year earlier and significantly exceeding market expectations for a ¥120 billion shortfall.

The June figures marked the second consecutive monthly trade deficit, underscoring how stronger domestic demand and higher import costs are offsetting resilient export performance.

Yen Falls to Its Weakest Level Since 1986

The Japanese currency weakened beyond ¥163 per dollar, extending its decline to the lowest level in nearly four decades.

The move reflected a combination of external and domestic pressures.

Escalating tensions in the Middle East pushed crude oil prices higher, increasing costs for Japan, which remains heavily dependent on imported energy. At the same time, a stronger U.S. dollar and rising Treasury yields continued to widen the interest-rate gap between the United States and Japan, encouraging investors to maintain carry-trade positions funded in yen.

Domestic factors also added pressure after the Japanese government unveiled large-scale fiscal spending plans, while the Bank of Japan maintained its cautious approach toward monetary policy normalization, reinforcing expectations that Japanese interest rates will remain comparatively low.

Record Imports Push Trade Back Into Deficit

Imports climbed 25.4% year-on-year to a record ¥11.34 trillion, accelerating sharply from 12.5% growth in May and comfortably exceeding market expectations of a 21.0% increase.

The June reading represented the strongest import growth since November 2022 and marked the fifth consecutive month of expansion, reflecting resilient domestic demand supported by government stimulus measures introduced in late 2025.

Imports increased across most major trading partners, including:

• United States: +52.7%

• Taiwan: +49.1%

• South Korea: +32.2%

• China: +29.4%

• ASEAN: +25.5%

• Hong Kong: +20.9%

• European Union: +1.6%

Meanwhile, imports from the Middle East declined 3.9%, even as crude oil imports surged 59.3%, reflecting Japan's continued effort to diversify energy procurement away from the Strait of Hormuz amid ongoing regional tensions.

By product category, imports increased across the board, led by:

• Electrical machinery (+32.1%)

• Manufactured goods (+34.3%)

• Chemicals (+25.4%)

• Machinery (+19.7%)

• Transport equipment (+12.5%)

Export Growth Remains Exceptionally Strong

Despite the return to a trade deficit, Japan's export sector continued to demonstrate remarkable resilience.

Exports rose 19.3% year-on-year to ¥10.93 trillion, marking the strongest annual increase since November 2022 and extending export growth to a tenth consecutive month.

The result also exceeded economists' expectations for an 18.6% increase.

Demand remained robust across Japan's major export destinations, including:

• Vietnam: +32.6%

• European Union: +20.3%

• ASEAN: +20.0%

• China: +17.6%

• United States: +13.0%

Exports to the Middle East, however, declined 4.2%.

The expansion was driven by broad-based gains across several industries, including electrical machinery, semiconductor equipment, transport equipment, scientific and optical instruments, non-ferrous metals, plastics, and other manufactured products.

Strong global demand for AI-related semiconductors and data center equipment continued to support overseas shipments despite supply chain disruptions associated with the conflict involving Iran.

Energy Costs Continue to Shape Trade Flows

The latest figures underscore the growing influence of geopolitical developments on Japan's external sector.

Higher crude oil prices and changing energy supply routes have significantly increased import costs, while Japan's effort to reduce reliance on the Strait of Hormuz has altered trade patterns across energy markets.

Although exports remain healthy, rising energy bills continue to absorb much of the benefit generated by the weaker yen.

EcoPulse24 Analysis

Japan's latest economic data tells a more nuanced story than the headline trade deficit alone suggests.

On one side, the weakening yen continues to provide a powerful competitive advantage for exporters. Shipments expanded at their fastest pace in more than two years, supported by sustained global demand for semiconductors, AI infrastructure, and advanced manufacturing equipment. The tenth consecutive month of export growth highlights that external demand remains resilient despite geopolitical disruptions.

On the other side, the same weak currency is becoming increasingly costly for an economy that relies heavily on imported energy and industrial inputs. Record import values, together with a 59.3% jump in crude oil imports, demonstrate how currency depreciation and elevated energy prices are feeding directly into Japan's import bill.

The yen's slide beyond ¥163 per dollar also increases the likelihood that authorities may face renewed pressure to stabilize the currency should volatility intensify further. At the same time, the Bank of Japan's gradual approach to policy normalization and expanding fiscal spending continue to reinforce expectations that interest-rate differentials with the United States will remain wide.

Ultimately, Japan is benefiting from a weaker yen through stronger exports, but paying a growing price through higher import costs. Whether that trade-off remains sustainable will depend largely on the trajectory of global energy prices, U.S. monetary policy, and continued demand for AI-related technology exports.
