The RBA Weighted Mean CPI YoY is a key financial indicator used by the Reserve Bank of Australia to measure the average change in prices of goods and services over a one-year period. This indicator provides valuable insights into the overall inflation rate and helps inform monetary policy decisions. It is calculated using a weighted average of the Consumer Price Index (CPI) for various categories, providing a comprehensive view of price movements in the Australian economy.
Inflation prints feed directly into central-bank policy expectations and real-yield calculations, and are among the most rate-sensitive releases on the calendar. The release is more useful as part of a longer-run signal than as a single-print catalyst. Released monthly.
Latest reading (Jan 2021): actual 1.3 %, consensus 1.3 %. Prior reading (Oct 2020): 1.4 %. Before that (Oct 2020): 1.4 %.
Sigmacast's 1-month forecast points to a similar reading versus the latest print. The 1-month and 3-month horizons disagree, suggesting a mixed signal. Trend-driven dynamics are the primary neutral force in the current projection. This indicator correlates most strongly with AUD/USD (Bullish AUD, r=0.55) — a useful reference for forex-focused traders.
