Tokyo’s CPI excluding fresh food rose 1.3% year on year in May, a softer reading than expected. The market forecast had been 1.5%, leaving the outturn 0.2 percentage points below consensus.
The result points to a slower pace of price growth in the capital on this core measure, which is widely monitored as a proxy for underlying inflation trends in Japan.
Implications For Bank Of Japan Policy And The Yen
The lower-than-expected Tokyo CPI figure suggests inflationary pressures in Japan are not as strong as anticipated. This gives the Bank of Japan (BoJ) significant reason to delay any interest rate hikes or reduction in its asset purchases. We believe the central bank will maintain its accommodative policy stance through the summer.
This data reinforces the view of continued yen weakness, driven by the widening interest rate gap with other major economies. The U.S. Federal Reserve, for instance, is maintaining its policy rate above 5%, creating a yield differential of over 500 basis points that heavily favors the dollar. We see a path for USD/JPY to test its multi-decade highs seen back in 2024, potentially pushing towards the 162 level.
Trading Strategies And Equity Market Outlook
For derivatives traders, this points to buying call options on the USD/JPY pair. An alternative strategy is to establish carry trades, borrowing in the low-cost yen to invest in higher-yielding currencies like the U.S. dollar or Mexican peso. We expect this environment to persist as long as the BoJ remains hesitant to tighten policy.
The weaker yen should also act as a tailwind for Japanese equities, particularly for large exporters. We view long positions in Nikkei 225 futures as a favorable trade. Looking at historical data from 2022 to 2024, a depreciating yen consistently correlated with strong gains in the Nikkei as corporate profits from overseas swelled.
We should be mindful of potential verbal intervention from the Ministry of Finance if the yen’s depreciation becomes too rapid. However, without a fundamental policy shift from the BoJ, any such intervention is likely to create only short-term volatility and better entry points. The underlying pressure on the yen will remain until the BoJ signals a clear move towards normalization.
