Japanese Finance Minister Shunichi Suzuki stated on Friday that authorities are monitoring currency movements with a strong sense of urgency. However, market participants remained perplexed by the yen's sharp fluctuations earlier in the day. Suzuki told reporters at the Ministry of Finance, "We are watching with a high sense of urgency as always." He declined to answer questions about whether authorities had intervened in the market.

The yen experienced violent swings around the conclusion of Bank of Japan Governor Kazuo Ueda's press conference. This followed a widely anticipated decision by the BOJ's policy committee earlier in the day to leave its benchmark interest rate unchanged. Within minutes of Ueda finishing his remarks, the yen plummeted to 159.23 per dollar, only to rebound sharply to 157.37 just a few minutes later.

Following comments from Finance Minister Suzuki, the yen gave back some of its gains, trading at 157.97. Masato Kanda, the top official in charge of currency affairs, told reporters he had no intention of commenting at this time on whether the government had stepped in to support the yen. He also declined to comment on whether rate checks had been conducted.

In 2024, when the yen breached the 160 level, authorities intervened four times, spending nearly $100 billion to buy the Japanese currency. This action has established a rough reference point for market participants regarding the potential timing of future intervention by the Ministry of Finance.

Officials have stated they do not have a specific, predetermined level in mind for intervention, but rather act to counter sudden, disorderly, or speculative movements. Economist Taro Kimura said, "Ueda mixed hawkish and dovish signals to maintain flexibility on the timing of the next rate hike. He highlighted the risk that a weak yen could boost inflation expectations by raising import prices."

Japanese markets have been on edge this week after Prime Minister Takaichi Sanae pledged to suspend the 8% consumption tax on food and non-alcoholic beverages for two years if she and her Liberal Democratic Party win a snap election on February 8th. Growing concerns that expanded government spending could worsen Japan's debt burden, which is the largest among developed economies, pushed the yield on 40-year Japanese government bonds to a record high earlier this week. These worries have also weighed on the yen's performance.
