About CPI Purchasing Power of Dollar — United States
DEFINITION
US CPI Purchasing Power of Dollar held steady at 29.900000 in August, matching July’s level. The reading for August shows no change from July’s 29.900000, continuing a gradual decline from 30.9 in November 2025. Market focus remains on inflation trends as the Federal Reserve maintains its current policy stance. Updated 10/4/26
WHY THIS INDICATOR MATTERS
Inflation prints feed directly into central-bank policy expectations and real-yield calculations, and are among the most rate-sensitive releases on the calendar. Surprises against consensus can drive short-term moves, particularly when the print breaks an established trend. Released monthly.
WHAT CHANGED THIS MONTH
Latest reading (Aug 2026): actual 29.9 Index 1982-84=100. Prior reading (Jul 2026): 29.9 Index 1982-84=100. Before that (Jun 2026): 29.9 Index 1982-84=100.
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 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 XAU/USD (Bearish XAU, r=-0.63) — a useful reference for commodities-focused traders.
