August Tokyo CPI came in broadly in line with expectations, as the resumption of electricity and gas subsidies weighed on inflation and is expected to continue pulling down the headline rate through the October release. Non-fresh food inflation cooled even as upstream cost pressures persisted, suggesting the pass-through to consumer prices is taking longer than anticipated.
Services inflation, meanwhile, accelerated, driven mainly by rents and medical charges. While the impact on nationwide CPI has so far been limited, underlying price pressure remains and the backdrop points to firmer repricing activity in coming months. A Teikoku Databank survey indicates another wave of price revisions toward year-end, a development consistent with a continued hawkish path for the BoJ.
Subsidies Mask Underlying Inflation Pressures
We see today’s Tokyo CPI figures confirming that temporary energy subsidies are successfully masking broader inflationary pressures, which will likely suppress headline figures through October. However, core inflation, excluding fresh food, still holds steady near 2.4%, showing that the underlying trend remains robust. This divergence means derivative traders should not be fooled by softer headline numbers in the coming weeks.
Positioning for Hawkish BoJ Policy and Persistent Inflation
We believe the Bank of Japan remains firmly on its hawkish path, supported by rising services inflation and expectations of year-end price hikes. Currently, overnight index swaps are pricing in a nearly 60% chance of another interest rate hike by the December meeting. Traders should use this temporary, subsidy-driven dip in CPI to position for higher interest rates.
We recommend focusing on shorting ten-year Japanese Government Bond futures, as yields are bound to rise once the subsidy distortions clear. Additionally, buying Japanese Yen call options against the US Dollar could yield strong returns as the policy divergence between the BoJ and other central banks widens. Volatility in the currency space is currently underpricing the BoJ’s hawkish resolve.
We also note that service sector inflation, driven by rising rents and medical costs, is starting to anchor itself firmly above 2%. While non-fresh food inflation has slowed temporarily, upstream wholesale costs are still climbing and will likely trigger a new wave of price revisions by year-end. Positioning in short-term interest rate swaps now allows us to capitalize on the market’s eventual realization of this persistent inflation.
