This decision comes in response to escalating property prices and accelerated credit growth. Recent data indicates that property investors now account for two in every five new home loans, with investor lending surging nearly 18% in the September quarter compared to the previous three months. Such rapid growth has raised concerns about the sustainability of the housing market and the potential for financial instability.

APRA's chair, John Lonsdale, emphasized the importance of this intervention, stating that the regulator is prepared to implement additional limits if macro-financial risks continue to rise or if there is a deterioration in lending standards. This proactive approach aims to ensure that the financial system remains resilient amidst the current economic climate.

For borrowers, this new cap means that obtaining high DTI loans will become more challenging. Lenders will need to be more stringent in their assessments, potentially leading to a reduction in the availability of such loans. Prospective homebuyers and investors should be prepared for more rigorous scrutiny of their financial positions and may need to explore alternative financing options.

In summary, APRA's introduction of a cap on high DTI home loans is a strategic move to safeguard the Australian housing market from potential risks associated with excessive borrowing. Borrowers are advised to stay informed about these changes and consider seeking professional financial advice to navigate the evolving lending landscape.
