About Retail Sales MoM — South Korea
DEFINITION
Retail Sales MoM (Month-over-Month) is a key economic indicator that measures the change in the total value of goods and services sold by retail stores in a given month compared to the previous month. This indicator provides valuable insights into consumer spending patterns and overall economic growth, making it a crucial tool for investors, businesses, and policymakers. A positive MoM growth in retail sales indicates a strong consumer demand, while a negative growth may signal a slowdown in economic activity. Retail Sales MoM is widely used to assess the health of the retail sector and its impact on the broader economy.
WHY THIS INDICATOR MATTERS
Consumer activity accounts for the majority of GDP in advanced economies, making spending data a key cyclical signal for retail and discretionary sectors. The release is more useful as part of a longer-run signal than as a single-print catalyst. Released monthly.
WHAT CHANGED THIS MONTH
Latest reading (Jul 2026): actual -2.4 %, consensus -2 %. Prior reading (Jun 2026): 2.7 %. Before that (May 2026): 0.1 %.
WHAT'S NEXT
Sigmacast's 1-month forecast points to a 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.
