Katayama said the government is prepared to take all possible steps in currency markets if necessary, highlighting the link between higher oil prices and Japan’s exchange rate.Japan imports nearly all of its energy, making the country particularly sensitive to spikes in crude prices. A weaker yen can compound those pressures by raising the cost of imported fuel and raw materials.The comments come as USD/JPY approaches the 160 level, a threshold widely viewed by traders as a potential danger zone for Japanese currency intervention. The Ministry of Finance last intervened in the foreign exchange market in 2024 when the yen weakened sharply.Katayama also said Tokyo is in close contact with U.S. authorities on foreign exchange matters, reinforcing the government’s readiness to coordinate with international partners if market conditions become disorderly. I bolded that, Japanese authorities like to wield the 'US" as a big stick. Officials in Japan have repeatedly emphasised that excessive or speculative currency movements are undesirable, particularly when they threaten to amplify inflation pressures through higher import costs.With energy markets under strain and the yen weakening, the government’s latest remarks appear aimed at signalling a stronger willingness to act if volatility intensifies.While Katayama did not specify a particular exchange-rate level that would trigger intervention, the comments underline rising concern within Japanese authorities that higher oil prices and currency weakness could combine to increase pressure on the domestic economy.For markets, the message is clear: Tokyo is watching developments closely and stands ready to respond if the combination of rising energy prices and yen depreciation begins to disrupt economic stability.
