About GDP Price Index YoY — Japan
DEFINITION
The GDP Price Index YoY is a key financial indicator that measures the change in prices of all goods and services produced within a country over a one-year period. It provides valuable insights into the overall inflationary trends and the purchasing power of consumers, making it a crucial tool for assessing the health of a country's economy. This indicator is closely monitored by policymakers, investors, and businesses to make informed decisions and forecast future economic conditions.
WHY THIS INDICATOR MATTERS
Aggregate growth figures anchor cyclical positioning across asset classes and inform fiscal and monetary policy debate. The release is more useful as part of a longer-run signal than as a single-print catalyst. Released quarterly.
WHAT CHANGED THIS MONTH
Latest reading (Jan 2026): actual 3.2 %, consensus 3.4 %. Prior reading (Jan 2026): 3.4 %. Before that (Oct 2025): 3.4 %.
WHAT'S NEXT
Sigmacast's 1-month forecast points to a similar reading versus the latest print, with the 3-month outlook reinforcing that direction. Both horizons are aligned bearish for this indicator, suggesting a consistent trend signal. Trend-driven dynamics are the primary headwind in the current projection. This indicator correlates most strongly with Nikkei 225 (Bullish Nikkei 225, r=0.82) — a useful reference for index-focused traders.
