Taro Kono, a member of Japan’s ruling party, has advocated for higher Bank of Japan rates since mid-2024. He reiterated this stance in a recent conference, emphasising the need to raise rates to strengthen the yen.
Kono pointed out the issues caused by the yen’s weakness against the dollar, such as inflation’s impact on domestic prices. At the time he began his calls for higher rates in July 2024, the USD/JPY exchange rate was approximately 158.
Renewed Calls For A Stronger Yen
Renewed calls from political figures like Taro Kono for a stronger yen through higher interest rates are a significant signal. We have been monitoring this sentiment since it first emerged in mid-2024. With USD/JPY currently trading near 162, the political pressure on the Bank of Japan (BoJ) to act is intensifying.
The central bank has been very cautious, with its policy rate sitting at just 0.25% more than a year after it ended its negative interest rate policy. This political push against the BoJ’s gradual approach creates uncertainty, which typically increases volatility. Therefore, we expect implied volatility on yen currency pairs to rise ahead of the next BoJ meeting in September.
Derivative traders should consider buying JPY call options or, more directly, USD/JPY put options. This strategy offers a defined-risk way to profit from a potential sharp drop in USD/JPY if the BoJ surprises the market with a hawkish statement or an actual rate hike. The current environment makes such a surprise more plausible than it has been in months.
Persistent Inflation And Market Reaction
Our outlook is reinforced by Japan’s persistent inflation, with the latest core Consumer Price Index for July 2025 coming in at 2.8%, still well above the bank’s target. Even as the U.S. Federal Reserve has slowly cut its own rates to 4.5%, the massive interest rate differential continues to weigh on the yen. This economic reality gives political calls for a rate hike more credibility.
We should not forget the market’s reaction to the BoJ’s unexpected policy adjustment back in December 2022, which sparked a significant yen rally. The current setup feels similar, where market complacency could be punished by a sudden policy shift. A verbal intervention hinting at future action is a distinct possibility in the next few weeks.
