CBA Chief Warns of Unsustainable Housing Credit Amid Price Surge

Post by : Bianca Suleiman

Australia's leading financial institution is issuing a rare warning. Matt Comyn, CEO of Commonwealth Bank, has indicated that the current pace of housing credit growth may not be sustainable as property prices continue to escalate in major urban areas.

During a hearing with members of parliament and the Economics Committee, Comyn reported that total housing credit growth is around 6 percent, with investor loans seeing an even higher trajectory. He remarked, “To ensure long-term financial stability, a reduction in credit levels would be advantageous.”

Real Estate Market Booming

According to recent data from the Australian Bureau of Statistics, new dwelling loan commitments saw a year-on-year increase of 6.4 percent in the September quarter of 2025, with the total value of loans surging nearly 10 percent. The rise in investor loans raises questions about whether regulatory intervention is necessary to temper demand.

Senator Barbara Pocock has urged APRA to restrict investor lending, claiming it has become “the largest unacknowledged leviathan of house price inflation.” She highlighted the urgent need to prioritize loans for owner-occupied housing over investment properties.

Mortgage Default Rates Remain Low

Despite the uptick in credit, Commonwealth Bank has reported that mortgage default rates are exceptionally low, largely attributed to consistent unemployment levels over the last four years. Currently, 85 percent of mortgage holders are ahead on their payments. Comyn warned, however, that a shift in unemployment could significantly impact these statistics.

The bank is also closely monitoring housing demand following the lack of anticipated further rate cuts, suggesting a potential softening of market activity.

Wider Economic Challenges

Comyn provided a cautious outlook on the global economy, referencing structural issues like geopolitical unrest, changes in trade dynamics, technological evolution, decarbonization efforts, and shifting demographics. He emphasized that these trends demand resilience from financial institutions to protect their operations and the overall banking framework.

He underscored that banks need to ensure profitability not just for returns, but to cover both anticipated and unexpected lending risks. For instance, a $500,000 loan necessitates setting aside $15,000 for potential losses, which can escalate rapidly if there are repayment issues.

As the House of Representatives Economics Committee continues its hearings with Australia's major banking institutions, topics such as mortgage interest rates, bank fees, the closure of regional branches, scam defenses, and AI integration will come under scrutiny. Comyn's observations highlight the fragile equilibrium between bolstering housing markets and securing long-term financial stability.
