Westpac Posts $6.8B Profit While Forecasting 11% Australian House Price Decline by March

The Quick Take

• Westpac posted $6.8 billion in annual profit while warning Australian house prices will fall more than 10% by March.
• Australia's second-largest lender expects interest rates to remain elevated, compressing mortgage affordability.
• The simultaneous profit beat and housing warning creates a bifurcated narrative for Australian banking investors.
• Westpac's house price forecast, if accurate, would represent the largest correction since the 2008-09 financial crisis.

Westpac, Australia's second-largest lender by assets, delivered $6.8 billion in annual profit while simultaneously issuing a stark warning that Australian house prices will decline more than 11% by March 2026, driven by the RBA's elevated interest rate trajectory and deteriorating mortgage affordability. The results mark a pivotal inflection for Australian bank earnings: the tailwind of higher net interest margins from rate increases is now being partially offset by rising mortgage stress, higher provisioning requirements, and the prospect of a meaningful house price correction affecting collateral values across the residential loan book. Westpac's forecast represents one of the most explicit guidance downgrades for Australian property from a major institutional lender.

For ANZ, CBA, and NAB — Westpac's peer competitors — the explicit house price decline forecast raises questions about whether all four major banks have provisioned adequately for a synchronized property correction. Mortgage insurance providers and property developers face the most direct negative impact, as an 11% house price decline would trigger loan-to-value ratio breaches on recent high-LVR originations. Household consumption in Australia is highly correlated with house price sentiment, meaning the correction Westpac is forecasting creates second-order impacts on retail sector revenues, consumer confidence surveys, and the broader Australian GDP growth trajectory through 2026.

Watch for the Reserve Bank of Australia's November rate decision and accompanying statement — any signal of a pivot to cutting rates would materially alter Westpac's house price decline scenario, as the forecast explicitly assumes rates remain elevated. Key data to watch includes the monthly CoreLogic house price index, which will provide real-time tracking of whether Westpac's 11% decline forecast is materializing on schedule. The macro variable is RBA CPI response: if Australian inflation prints below 3% in Q4 2026, rate cut expectations will reprice rapidly and potentially short-circuit the severity of the house price correction Westpac has flagged.
