due to Japanese Prime Minister Sanae Takaichi issuing a warning about abnormal exchange rate fluctuations, traders will be on high alert at the beginning of this week to guard against Japanese government intervention aimed at stopping the recent decline of the yen — this action may even receive rare assistance from the United States. Michael Brown, Senior Research Strategist at Pepperstone Group, stated: "Exchange rate checks are usually the last warning before intervention actions are taken. The Takaichi administration's tolerance for foreign exchange speculation appears to be much lower than that of its predecessor." Reports about exchange rate checks may deter the market from further shorting the yen, thereby squeezing yen short positions that have reached their largest increase in more than a decade. In the last few trading hours of last week, the yen experienced sharp fluctuations, reversing from a downward trend toward 2024 lows, surging 1.75% against the dollar to 155.63 at one point, marking the largest single-day gain since August last year. Nick, Chief Analyst at AT Global Markets, pointed out that if the United States participates in the potential exchange rate check, its impact would not be limited to the yen but could also affect global markets.
