Japan and the U.S. just spent billions to try to save the yen. Why is it already losing ground?

**Yen's Rollercoaster Ride: Japan and U.S. Spend Billions, Yet Currency Loses Ground**

Despite a joint intervention by the U.S. and Japan, worth billions of dollars, the Japanese currency has already lost half of its post-intervention gains, sparking concerns about the effectiveness of the unprecedented move. The yen, once trading at a 40-year low, has been on a rollercoaster ride since the U.S. and Japan's finance ministries stepped in to bolster its value. The development raises questions about the underlying reasons behind the yen's weakness and whether the intervention is merely a temporary fix.

Background & Context

The yen's decline has been a long-standing issue, dating back to 2012 when it traded at around 78 to the dollar. Since then, the currency has been steadily losing ground, with corporate Japan initially welcoming a weaker currency to boost exports. However, as import costs have risen, companies have started to feel the pinch, and a weaker currency has also led to increased cost of living concerns for consumers.

The Bank of Japan's data suggests that the Japanese government sold as much as $58.97 billion to buy the yen, while the U.S. Treasury Secretary Scott Bessent and Japan's Finance Minister Satsuki Katayama pledged to intervene again if needed. The joint intervention was the first of its kind since 1998, and both countries have been working closely to address the yen's weakness.

Key Details

The yen began the year at 156 to the dollar before steadily weakening to 163 by late July. Following the intervention, the yen strengthened to 157 to the dollar, but it has since fallen back to 159, indicating a loss of half its post-intervention gains. Traders reported that the U.S. sold euros rather than dollars to fund its yen purchases, which analysts suggested was necessary to limit disruption to the U.S. Treasury market.

According to Reuters, the U.S. and Japan have discussed a joint intervention as early as January, with conversations intensifying after Bessent's visit to Japan in May. The size of the U.S. action is unknown, but a photograph of Bessent's notepad at a Friday cabinet meeting revealed a note to "Buy Japanese Yen (JPY) $5-10 bil."

What Experts Say

Economists point out that the U.S.-Japan intervention does not address the underlying reasons behind the yen's weakness, including a large gap between U.S. and Japanese interest rates and concern about fiscal profligacy on the part of Japan's government. The fact that better yields can be found elsewhere has also contributed to the yen's decline.

"A weak yen does not necessarily mean all is well," Mitsubishi Electric chief financial officer Kenichiro Fujimoto told Reuters. The Bank of Japan's data suggest that the Japanese government's sales of the yen have been significant, with the country selling as much as $58.97 billion. The U.S. involvement was likely due to a need to maintain "stable U.S. Treasury yields by limiting pressure from Japanese sales," wrote David Meier, an economist at Julius Baer.

Key Takeaways

• The yen has lost half of its post-intervention gains, raising concerns about the effectiveness of the joint intervention.
• The U.S. and Japan's finance ministries sold as much as $58.97 billion to buy the yen, with the U.S. involvement likely due to maintaining stable U.S. Treasury yields.
• The joint intervention does not address the underlying reasons behind the yen's weakness, including a large gap between U.S. and Japanese interest rates.
• The yen's decline has significant implications for corporate Japan, with rising import costs and increased cost of living concerns for consumers.

What This Means For You

The yen's rollercoaster ride has significant implications for everyday readers, particularly those who rely on imports or have investments in Japan. The joint intervention may provide temporary relief, but it does not address the underlying reasons behind the yen's weakness. As a result, the yen's decline may continue, leading to increased costs for consumers and reduced profitability for companies.

In the long term, the yen's decline may lead to increased pressure on the U.S. Treasury market, as Japan is the largest foreign holder of U.S. Treasuries, totaling $1.2 trillion in holdings. If Tokyo were to decide to sell Treasuries to fund its yen intervention, it would have significant implications for the global economy.

As the yen continues to fluctuate, it is essential for investors and consumers to remain vigilant and adapt to changing market conditions. The joint intervention may be a temporary fix, but it does not address the underlying structural issues that have led to the yen's decline.
