About Gross Domestic Product YoY — Japan
DEFINITION
Japan's Gross Domestic Product YoY came in at 1.100000% for August, missing the 2.000000% estimate. This marks a decline from May's 2.100000%, indicating a slowdown in economic growth. The weaker reading may influence market expectations and monetary policy considerations ahead of upcoming data releases. Updated 8/17/26
WHY THIS INDICATOR MATTERS
Aggregate growth figures anchor cyclical positioning across asset classes and inform fiscal and monetary policy debate. Surprises against consensus can drive short-term moves, particularly when the print breaks an established trend. Released monthly.
WHAT CHANGED THIS MONTH
Latest reading (Apr 2026): actual 1.1 %, consensus 2 %. Prior reading (Jan 2026): 2.1 %. Before that (Oct 2025): 0.2 %.
WHAT'S NEXT
Sigmacast's 1-month forecast points to a materially higher reading versus the latest print, with the 3-month outlook reinforcing that direction. Both horizons are aligned bullish for this indicator, suggesting a consistent trend signal. Trend-driven dynamics are the primary tailwind in the current projection. This indicator correlates most strongly with USD/JPY (Bullish JPY, r=-0.50) — a useful reference for forex-focused traders.
