The Japanese Yen has fallen below 160 per US Dollar, which was the last time it was at this level in July 2024, causing a raise of speculation that Japan’s Ministry of Finance may intervene in the Foreign Exchange (FX) market. Since April 2025, the US dollar has gained 14% value against the yen, resulting in Japan’s Vice Finance Minister for International Affairs, Atsushi Mimura, cautioning that “decisive action” might be required to deter speculation.
Since 2022, Japan has already spent nearly $150 billion on several interventions to prop up the Yen, the most significant one was the period of April-July 2024, when $95 billion was injected. The latest breaking of the 160 mark has put more Yen under pressure, and Mimura’s statement implies that officials are keeping a very close watch on the developments.

Japan’s potential FX intervention might lead to reverberations in crypto markets as well. In the event that the yen gains strength, it is likely that there will be a rise in interest towards cryptocurrencies, especially those that have a Japan-heavy market like Bitcoin and Ethereum. However, the determining factors will still be how successful the intervention is and the overall sentiment of the market.

Experts point out that the Japanese government may step into the FX market if the USD/JPY rate moves beyond the 162-164 levels. Hence, the Japanese Central Bank’s perspective on interest rates will significantly influence the depreciation or recovery of the yen. Since the annual inflation rate in Tokyo is 1.7%, it is likely that the Bank of Japan will take a very measured stance towards raising interest rates, which might be a factor in supporting the yen.
There is an increasing likelihood of FX intervention in Japan due to the weakening yen and enhanced speculative activities. Even though this may impact the crypto market, the final decision is still unknown. The investment community should keep an eye on the changes in the FX market and revise their investment plans accordingly.
