The Japanese yen (JPY) has gained strength recently, partly due to speculation about potential government intervention. The USD/JPY exchange rate fell from 159.23 to 153.40, indicating that a joint action by the U.S. and Japan may be on the horizon.

Speculation About Intervention

The New York Federal Reserve has contacted financial institutions about the JPY market. Both Japanese officials and the U.S. Treasury Secretary have expressed worries about the yen’s weakness. The last time the U.S. and Japan coordinated action in the foreign exchange market was in March 2011. There is increasing caution among market participants about the possible impact of JPY-funded carry trades if the yen keeps gaining strength. This situation could hurt high-beta currencies like the Australian dollar (AUD) within the G10. While the situation remains unclear, analysts are keeping a close eye on developments. The Japanese yen’s sharp rise is affecting the market. The USD/JPY has dropped significantly from the 159 level to the mid-153s, indicating that the possibility of government intervention is now being taken seriously. Reports suggest that U.S. authorities are actively looking into the state of the yen market. This potential coordinated action between the U.S. and Japan is a significant event, as we haven’t seen anything like this in over a decade. In autumn 2022, Japan alone spent over ¥9 trillion on interventions, which caused major fluctuations in the currency. With U.S. Treasury concerns now on the table, any action could have a long-lasting impact, more so than past efforts.

Currency Strategy

The last joint U.S.-Japan intervention occurred in March 2011, highlighting that this tool is used for serious issues. Given the current uncertainty, traders might want to consider buying JPY volatility through options. The currency volatility index, which was low for most of 2025, is likely experiencing a sharp increase, making it a wise strategy to prepare for wider price swings. For those who have a specific view, buying JPY calls (or USD/JPY puts) is a clear way to position for further yen strength. If authorities aim to lower the dollar from the highs seen in late 2025, a move back toward the 145-150 range is quite possible. These options offer a clear way to participate in such a move with defined risk. It’s also important to monitor the unwinding of JPY-funded carry trades, a previously successful strategy. As the yen gets stronger, the cost of repaying cheap JPY loans rises, which forces traders to sell high-yield currencies they’ve purchased. This creates a ripple effect that can spread quickly through various markets. This unwinding can directly impact currencies that have performed well throughout 2025, such as the Australian dollar and Mexican peso. Derivative traders should consider buying puts on pairs like AUD/JPY to protect against or profit from further declines in these trades. The recent strength of these high-beta currencies is now genuinely at risk. Create your live VT Markets account and start trading now.
