Yen Plunges to Four-Decade Low, Rattling Japan's Economy Amid Import inflation Fears

Yen Plunges to Four-Decade Low, Rattling Japan's Economy Amid Import inflation Fears​

The Japanese yen has experienced a significant slump, trading at its weakest level against the US dollar since 1986. This historic depreciation is causing considerable unease across Japan and has placed financial regulators on high alert regarding market stability.

Global Financial Markets React to Yen’s Historic Decline​

The currency recently depreciated by up to 0.1%, hitting 161.96 against the US greenback, breaching the 161.95 mark first seen in July 2024. This level is notable because it was last reached when the yen was rapidly appreciating during a major rally engineered by the US.

Currently, Japan is navigating a period of economic difficulty after a generation of stagnation. While this currency weakness boosts profits for exporters and helps the nation's stock market achieve highs, the downside risks are clear.

Inflationary Pressures Threaten Domestic Stability​

A primary concern stemming from the yen’s soft performance is the increasing cost of imports, particularly oil and gas shipments priced in dollars. The resulting inflation is negatively affecting consumers who are facing higher prices for essentials such as food and electricity.

This sustained inflationary pressure threatens to undermine the popularity of Prime Minister Sanae Takaichi's government. Structural challenges like the country’s aging and shrinking population exacerbate these woes, fueling a growing pile of public debt that weighs on prospects for significant rate hikes.

Central Bank Response and Government Intervention Efforts​

The yen’s decline has continued despite changes within the Bank of Japan (BOJ). The BOJ ended its negative-interest rate policy in 2024 by lifting the benchmark interest rate to 1% on June 16, which is the highest level since 1995. However, the impact of this move remains minimal as traders anticipate a continued hawkish stance from the Federal Reserve.

The Japanese government has also been actively involved in defense mechanisms. A record yen-11.73 trillion ($72.5 billion) intervention campaign was conducted between April 28 and May 27 after the yen first surpassed the 160 per dollar level. Finance Ministry reserve data suggest that this intervention likely involved drawing on foreign securities, including US Treasuries.

Policymakers Vow "Bold Action" Amid Speculative Pressure​

Japanese Finance Minister Satsuki Katayama reiterated on June 19 that authorities are prepared to take "bold action" to curb excessive speculative movements in the foreign exchange market.

Katayama also noted a growing alignment between Japan and the US on currency policy following her meeting with US Treasury Secretary Scott Bessent, affirming that both nations agreed to take "bold steps" on currencies if necessary.

Shaun Osborne, head of currency strategy at Scotiabank, commented that the Bank of Japan is closely monitoring developments after the yen breached the key level. The massive amount deployed in the recent intervention highlights not only the gravity of the situation for Japan but also the difficulty of resisting economic tides in the $9.5 trillion-a-day global foreign exchange market.
