Executive Summary
Perth's residential property market has undergone a dramatic structural transformation from chronic oversupply (2015—2019) to acute shortage (2020—present). With listings down over 80% from their peak, days-to-sell compressed to single digits, and rents doubling, the market exhibits characteristics of price discovery under duress rather than equilibrium clearing. This analysis situates Perth housing within the broader context of elevated Australian household debt and historically high global equity valuations, providing a framework for prudent decision-making.
Perth Residential Market: The Transformation
The Perth market has experienced a regime change from structural oversupply to chronic shortage. Understanding this shift is essential for contextualising current price levels and market behaviour.

| Period | Median House Price | Active Listings | Median Days to Sell | Market Condition |
|---|---|---|---|---|

|---|---|---|---|
| March 2015 | $440 | 31 | — |

The Demand Driver: Population Surge
Western Australia's population growth has re-accelerated to become the fastest of any Australian state, driven by net overseas migration and interstate inflows. This demand is concentrated in Greater Perth, overwhelming new housing supply.

The Leverage Context: Australian Household Debt
Australian household debt-to-income ratios remain among the highest in the developed world. This structural leverage provides the capacity for price escalation but also represents a prudential vulnerability.
Australian Household Debt Metrics
| Metric | Current Reading | Historical Context | Prudential Implication |
|---|---|---|---|
| Total Household DTI | ~182% | Near record; 5th highest in OECD | Structurally elevated |
| Housing Debt/Income | ~135% | Highest on record | Mortgage burden high |
| Interest Payments/Income | ~9.5% | Near 2008 GFC peak | Serviceability stretched |
| Borrowing Capacity | −30% | Due to APRA 3% buffer | Constrains new entrants |
| Loans in Arrears (90+ days) | <1% | Low but rising | Labour market key |
Aggregate Buffers Offset Risk
Australian households hold liquid assets approximately equal to their debt (~190% of income). Offset accounts and savings act as shock absorbers. The RBA notes this has dampened the transmission of rate rises to spending.
Risk Concentration
Highly leveraged borrowers (high LVR or LTI) are significantly more likely to fall into arrears. While aggregate figures appear manageable, a minority of households face genuine financial stress, particularly new borrowers at elevated prices.
Global Equity Valuations: The Broader Picture
The elevated conditions in Perth housing are mirrored by historically high equity market valuations globally. Both asset classes exhibit characteristics of "pricing at the margin" by urgent participants with capacity.
Equity Market Valuation Indicators
| Indicator | Current Reading | Long-Term Median | Historical Precedent |
|---|---|---|---|
| Shiller CAPE Ratio | ~40 | 16.04 | Exceeded only 1929, 1999—2000 |
| Buffett Indicator | ~220% | ~80% | 2.4σ above trend |
| S&P 500 Regular P/E | ~31 | ~17 | Elevated but not extreme |
| Implied 10-Year Return | ~1—3% p.a. | ~6.6% p.a. | Based on CAPE regression |

The Two-Dial Prudential Model
Traditional property clocks measure direction—is the market rising or falling? This misses the critical question of quality—is price being set in a fair, unpressured exchange? We propose a two-dial framework that separates cyclical position from prudential stress.
Measures market direction and the intensity of price drivers. The force that sets headline price.
Measures market quality, affordability, leverage, and the pressure on buyers. The cost to own.
Asset Class Positioning Matrix
| Asset Class | Price Cycle (Dial 1) | Prudential Stress (Dial 2) | Key Risk |
|---|---|---|---|
| Perth Housing | Approaching Peak | CRISIS | 8-day median sale; buyers under duress; 100% rent increase from trough |
| US Equities (S&P 500) | Highly Priced | TIGHT | CAPE ~40 (2.5× median); concentration in AI/tech themes |
| Australian Mortgage Debt | — | TIGHT | DTI 182%; interest payments near GFC peak; buffers depleting |
| Australian Equities | Rising | Moderate | Less extended than US; resources/banks dominate |
