Japan’s Consumer Price Index (CPI) for August 2025 increased by 2.7% compared to last year. This is lower than the expected 2.8% and down from last month’s 3.1%. This is the slowest inflation rate in nine months. The core-core CPI, which excludes fresh food and energy, rose by 3.3%, matching expectations but slightly lower than last month’s 3.4%. The core CPI, excluding fresh food but including energy, also rose by 2.7%, as expected, but fell from the previous 3.1%.

Global Economic Concerns

Tokyo’s headline CPI for August was reported at 2.6%, as expected. There are concerns regarding global economic issues, such as a potential 15-20% tariff on EU goods by the U.S. and upcoming monetary policy changes in Canada, Mexico, and the UK. Investors think that the Bank of Japan may be careful about raising interest rates, especially as inflation shows signs of slowing. There are expectations for rate cuts from central banks like the U.S. Federal Reserve and the Reserve Bank of Australia due to different economic pressures. With inflation in Japan slowing to 2.7%, expectations for a Bank of Japan rate hike soon have faded. This suggests a weaker yen may be on the way, as the gap between its policies and those of other central banks remains large. Consider using call options on USD/JPY with strikes around the 155 level to capitalize on this anticipated move. This sentiment is evident in the bond market, where the 10-year Japanese Government Bond (JGB) yield has dropped below 1.0% after the data release. The ongoing interest rate difference between the U.S. and Japan makes the yen attractive for carry trades. We saw a similar situation in late 2024 when speculation about rate hikes declined, leading to a strong rally in USD/JPY.

US Dollar Complexity

Meanwhile, the outlook for the U.S. dollar is becoming more complicated. Federal Reserve officials have noted a weakening labor market. The latest U.S. jobs report for August showed only 155,000 new jobs, reinforcing the idea that Fed rate cuts may come sooner rather than later. Therefore, any weakness in the yen could be more significant against currencies from central banks perceived as more aggressive. For equity derivatives, a cautious Bank of Japan is positive for Japanese stocks. A dovish policy keeps borrowing costs low and is likely to boost corporate sentiment, which could help the Nikkei 225 rise. Selling out-of-the-money puts on the index to collect premiums seems like a good strategy, betting that this policy environment will support the market. Despite these trends, implied volatility on currency pairs remains high, with 3-month USD/JPY volatility around 9.0%. This indicates that the market is preparing for possible policy surprises or external shocks, such as the U.S. tariff discussions. Therefore, using defined-risk option strategies, like bull call spreads, is a wise way to protect against unexpected changes in sentiment. Create your live VT Markets account and start trading now.
