Japan’s national CPI excluding fresh food rose 1.8% year on year in March. This matched the forecast of 1.8%.
With Japan’s core inflation coming in at 1.8%, exactly as expected, the data gives the Bank of Japan no reason to rush into another interest rate hike. This reading for March 2026 remains below the central bank’s 2% target, reinforcing our view that monetary policy will stay accommodative for the foreseeable future. Traders should see this as a green light for strategies that benefit from a cautious central bank.
The most direct implication is continued pressure on the Japanese Yen, especially as the interest rate gap with the United States remains wide, with the Fed funds rate sitting over four percentage points higher. We saw how the Yen weakened past 155 per dollar last year in 2025 before the Ministry of Finance stepped in, and conditions are now similar. Buying call options on USD/JPY seems like a sensible way to position for further Yen weakness in the coming weeks.
This environment is also supportive of Japanese equities, as a weaker Yen boosts profits for the country’s major exporters. The Nikkei 225 has already gained over 15% since the BoJ finally ended its negative interest rate policy in late 2025, showing the market prefers a slow and predictable path. We feel that long positions through Nikkei 225 futures or call options remain an attractive trade.
Given the lack of any inflationary surprise, volatility in the Japanese Government Bond (JGB) market is likely to remain subdued. The 10-year JGB yield has been steady, hovering just under 1.0% recently, and this inflation print won’t change that narrative. Traders could use options to bet on this low volatility continuing, selling strangles on JGB futures if they believe yields will stay within a tight range.
The primary risk remains a sudden shift in tone from the Bank of Japan or direct currency intervention from the government if the Yen’s decline accelerates too quickly. Implied volatility on Yen currency pairs is currently quite low, suggesting the market is not pricing in a major surprise event. This complacency could make protective put options on USD/JPY an inexpensive way to hedge against an unexpected policy shock.
