This policy is designed to mitigate potential financial risks associated with high DTI loans, which can make borrowers more vulnerable to economic shocks. By imposing this cap, APRA aims to ensure that lending practices remain prudent and that the financial system remains stable.

For borrowers, this change means that obtaining high DTI loans may become more challenging. Lenders are likely to tighten their assessment criteria, focusing more on borrowers' income levels and existing debt obligations. Prospective homebuyers and investors should be prepared for more stringent scrutiny during the loan application process.

It's important to note that while this cap is intended to reduce systemic risk, it may also impact the housing market by potentially slowing down the rate of new loan approvals for high DTI borrowers. This could lead to a cooling effect on property prices, particularly in markets where high DTI loans are more prevalent.

Borrowers are encouraged to assess their financial positions carefully and consider seeking advice from financial professionals to understand how these changes may affect their borrowing capacity and overall financial health.
