Serviceability Buffer Stays at 3%: Why Aussies Are Eyeing RBA Rate Cuts Instead
APRA has confirmed that the mortgage serviceability buffer will remain at 3%, a move that has many aspiring homeowners feeling the squeeze. Initially raised from 2.5% during the pandemic era, this buffer ensures lenders assess a borrower’s ability to service a loan at a rate 3% higher than the contract—making it tougher to qualify amid rising living costs and high property prices.
Why Does This Matter So Much?
When evaluating home loan applications, banks apply the buffer to ensure borrowers can handle future rate hikes. But with today’s cash rates already elevated, this extra margin can significantly restrict how much applicants are allowed to borrow—even if their finances are strong. APRA has defended the decision by pointing to high household debt levels, rapid credit growth, and ongoing global economic uncertainties.
Borrowers Feel the Heat—But Hope Rides on RBA
For many, the buffer is now the main barrier—not their income or deposit size. As APRA keeps its settings unchanged, potential buyers are now pinning their hopes on a different lever: a cash rate cut by the RBA. A reduction in the RBA’s official rate would lower lenders’ costs and potentially ease loan assessments—even if the buffer stays firm.
What This Means for Buyers
- First-home buyers and upgraders face blocked borrowing power—putting homeownership dreams further out of reach.
- Timing is everything: should the RBA finally cut rates, it could provide a much-needed boost to affordability.
- Strategic planning matters: borrowers could explore options like locking in lower fixed rates now, or preparing documentation to act swiftly once lending conditions improve.
Final Thoughts
With APRA ruling out any buffer reduction, the path to unlocking borrowing power may lie with future decisions from the RBA. If rate cuts come through, that could offer the only viable relief for buyers looking to enter the market in 2025.
