Japanese Yen Plunges to Near 40-Year Lows Amid Economic Woes

The Japanese yen has reached near 40-year lows against the U.S. dollar, driven by external shocks and long-term structural problems in Japan's economy.

Market analysts say that while short-term pressures from external factors like geopolitical tensions have contributed to the yen's decline, deeper causes include wide interest rate differentials between the United States and Japan, sluggish growth in emerging industries, rapid population aging, and other challenges.

Akira Nakaminato, a visiting professor at Japan's Tama University, notes that Japanese companies shifted production overseas not only due to exchange rates but also to stay close to local markets. Today, structural issues like a shrinking labor force and concerns over energy supplies undermine incentives for manufacturers to bring production back.

Tohru Sasaki, chief strategist of Fukuoka Financial Group, argues that exchange rate intervention alone addresses symptoms rather than underlying causes, emphasizing the need to tackle deeper issues such as persistent fiscal expansion, low interest rates, and economic imbalances for the yen's depreciation to reverse.
