Currently, approximately 10% of investor loans and 4% of owner-occupied loans exceed this DTI threshold. By implementing this cap, APRA aims to proactively manage the potential risks associated with high-risk lending practices before they escalate into more significant issues.

APRA Chair John Lonsdale emphasized the importance of this initiative, stating that it is a proactive step to address emerging risks from high-risk lending before they become disruptive. Given the banking system's substantial exposure to residential mortgages, this cap is designed to mitigate potential shocks related to the housing sector.

The decision follows a period of rapid housing price increases and an 18% surge in investor lending in the last quarter. Factors contributing to this trend include earlier interest rate cuts and various buyer incentives that have stimulated demand in the housing market.

Both Treasurer Jim Chalmers and the Australian Banking Association have expressed support for APRA's move, highlighting its significance in promoting responsible lending practices and maintaining a stable housing supply. Market analysts interpret this development as an indication that further policy easing is unlikely in the near future. With the current cash rate at 3.6%, there is speculation that interest rates may rise to counteract inflationary pressures.

For prospective homebuyers and investors, this policy change underscores the importance of assessing financial capacity and understanding the implications of high DTI ratios. It also highlights the need for lenders to exercise caution and diligence in their lending practices to ensure the long-term stability of the housing market.
