Higher readings indicate price movements are more volatile than the historical norm, a risk signal distinct from the direction of price movement itself. 2Metric Definition **Primary metric: Asset Volatility Risk Scalar, Z-Score** Z-Score Construction Current (Q2 2026)−0.3402σ **Metric typology:** Z-score of the Asset Volatility Risk Scalar, AVRSt = σP,8 × |ΔPt / P̄8| ÷ LIQt: eight-quarter price volatility, scaled by the latest quarterly price move and divided by owner-occupier loan commitments. 3Data Sources Tier-1 sovereign sources. Price: ABS Total Value of Dwellings (6432.0), mean price of residential dwellings. Liquidity: ABS Lending Indicators (5601.0), owner-occupier new loan commitments excluding refinancing, number, seasonally adjusted. Quarterly, N=51 (rolling 8-quarter window, from Q2 2013). No commercial data dependency exists in the node. 4Analytical Interpretation At −0.3402σ, price volatility sits slightly below its historical baseline. The mean dwelling price eased 0.7% in the June quarter 2026; price movements over the past eight quarters have been wide, but the small latest move keeps the score below average. The reading follows +1.18σ in the December quarter 2025, when the price rose 4.0% in a single quarter, and +0.03σ in the March quarter 2026. **Position.** 44.2, ranked against 53 quarters of the node’s record, from the June quarter 2013.
