Japan's trade balance swung to a deficit in May, a development that economists say could weigh on growth in the second quarter. The shift reflects the persistent impact of a weakened yen, which has inflated the cost of imports.

The deficit comes amid broader concerns about Japan's economic trajectory, with many analysts already anticipating a slowdown tied to the ongoing war in Iran. This external conflict adds further pressure to an economy heavily reliant on energy imports.

According to the Japan Times, the trade figures underscore how currency depreciation is reshaping Japan's trade dynamics. The yen's slide has made imports more expensive without a commensurate boost in export volumes, eroding the trade surplus.

The implications are significant for Japanese policymakers, who face the twin challenges of supporting growth while managing inflation. A sustained deficit could complicate the Bank of Japan's monetary policy stance.

The war in Iran remains a key variable, with its duration and intensity likely to influence both global energy prices and Japan's trade outlook in coming months.
