Japan Economic Flash: Raising Our FY2027 Inflation Forecasts Due to

Weaker Yen, Higher Memory Chip Prices, and Rebound in Food Prices

n The upward revision to our FY2027 forecasts reflect our forex research team’s

revised forecast (12-month forecast: from ¥155/US$ to ¥165/US$), a significant

rise in memory chip prices, and higher food prices partly due to weather factors.

While these factors will accelerate inflation not only in FY2027 but also in

FY2026, our FY2026 inflation forecast remains unchanged, since the rise in

private services prices is tracking below our forecast. Naphtha-flation (the rise in

naphtha-related product prices) took a breather in the June corporate goods

price index (CGPI, goods-PPI equivalent) print. This is consistent with our

forecast that the margin of price increases will narrow as pass-through

progresses downstream. We expect some price increases from June, mainly in

non-durable goods, but the margin of increase in retail prices, which are the

farthest downstream in the supply chain, is likely to be small.

n Meanwhile, our core CPI (excludes fresh food) forecasts for FY2026 and FY2027
