Japanese finance minister hints at intervention if the yen falls to 160.
As the yen continues to come under pressure, Japanese Finance Minister Mayumi Katayama issued a clear warning, hinting that the authorities are ready to take intervention measures, drawing a clear line of defense for the exchange rate in the market.
On Friday, according to Bloomberg, when asked about the issue of yen weakness, Katayama stated that the authorities will “respond firmly, including taking bold measures.” This wording, customary among Japanese officials, is often interpreted by the market as a signal of imminent FX intervention.
Before her remarks, the USD/JPY exchange rate hovered around 159.70, approaching the 160 mark—a trigger point for several interventions by Japanese authorities in 2024. Boosted by her comments, the yen briefly rose to 159.49, but the gains later narrowed.
This statement came against the backdrop of ongoing tensions in the Middle East and surging energy prices. The dollar was strong overall this month, with Bloomberg’s dollar spot index rising more than 2% due to safe-haven inflows and the market’s downward revision of Fed rate cut expectations. The direct trigger for the yen’s pressure was speculative selling sparked by rising oil prices.
160 Threshold: Historical Intervention Level Near Again
160 is a psychologically sensitive level for Japan's FX authorities.
In 2024, the Ministry of Finance intervened multiple times when the USD/JPY touched or exceeded this level, deploying funds totaling several trillion yen to support the currency. With the exchange rate nearing this mark again, the market is highly alert as to whether authorities will repeat their intervention actions.
Katayama’s statement continued the officials’ usual “verbal intervention” strategy—pressuring the market with rhetoric before actually tapping into foreign exchange reserves.
The yen’s brief strengthening after her remarks shows the market still reacts to such signals, but the gains did not last, indicating that investors remain cautious on whether the authorities will truly step in.
Oil Market Speculation: Intervention May Extend to Commodities
What’s notable is that Katayama not only focused on the exchange rate this time, but also extended attention to the commodity markets. She once again attributed the yen’s recent speculative pressure to oil market fluctuations, and stated that the authorities are closely monitoring wider market dynamics, including commodities.
According to a previous WallstreetCN article, the Japanese government is evaluating an unconventional plan—using FX reserves to directly intervene in the crude oil futures market by establishing short positions to push down oil prices, thus indirectly easing depreciation pressure on the yen. Finance Minister Katayama Mayumi on Tuesday shifted focus from speculative actions in forex markets to the crude oil futures market, stating the latter is disturbing exchange rate movements, and saying “The Japanese government is ready to take comprehensive action on all fronts at any time.”
On oil prices, Trump once again delayed the deadline for strikes on Iran’s energy infrastructure on Thursday, saying negotiations with Iran were “very smooth,” and promised not to attack Iranian energy facilities for now. This statement brought a brief retreat in oil prices; on Friday morning in Tokyo, the yen and Japanese government bond yields also got a short respite, but the effect was fleeting.
Katayama also revealed that a G7 meeting of energy and finance ministers will be held next week, with Middle Eastern tensions expected to be a core topic. At the same time, Katayama said the Japanese government will hold an emergency meeting on Friday with financial institutions to jointly study how to support companies facing financing pressure due to Middle Eastern conflicts.
