Three major factors are converging right now that could slash your borrowing power overnight.
Today, thousands of Australians are walking into auctions with pre-approval letters that became 'zombies' overnight. Between a new APRA 'quota' system that launched at midnight and a looming RBA hike on Tuesday, your 'Max Bid' isn't what it was on Friday. If you don't adjust your numbers by 10 AM, you're not just bidding for a house, you're bidding for a bank decline.
1. The "Quota Queue": Why your income just lost its power
The Signal
As of today, February 1, 2026, APRA's new 20% cap on high Debt-to-Income (DTI ≥ 6) loans is officially live.
Banks are now legally restricted: only 1 in 5 new loans can go to people borrowing more than 6x their gross income. If you're an investor with a portfolio or a high-leverage buyer in Sydney or Melbourne, you aren't just competing against other bidders—you're competing for a spot in the bank's quarterly "High DTI" allowance.
Reality check:
Your application might be perfect, but if you're applicant #21 this week and the bank has already approved 20 high-DTI loans, you're getting declined. Not because you're unqualified, but because of timing.
The Action:
If your ratio is over 6.0, we need to shift your application to non-bank lenders (who aren't bound by this cap) before you sign a contract.

2. The 48-Hour "Serviceability Cliff"
The Signal
The RBA meets this Tuesday. Markets are currently pricing in a 67% probability of a 0.25% hike to 3.85%.
ASX Market Data (January 29, 2026):
ASX 30-Day Interbank Cash Rate Futures February 2026 contract:
• Probability of NO CHANGE to 3.60%: 33%
• Probability of INCREASE to 3.85%: 67%
Note: This represents a dramatic shift from just 8 days earlier when the probability of an increase was only 25%. The market repriced rapidly following recent economic data releases.
A 0.25% hike is a "double hit." It increases your monthly interest AND forces the bank to test your "repayment buffer" at a higher floor. This can slash a $1.2M borrowing limit by $25,000+ in a single afternoon.
The Action
If you're heading to an auction this week, your Friday pre-approval is high-risk. Run a Borrowing Power Calculator at 3.85% + 3% buffer.
3. The "Scarcity Trap": Why "Stale" is the New "Shiny"
The Signal
Listing volumes in major hubs have plummeted 16.6% below the 5-year average.

Extreme scarcity is driving "panic bidding" on "shiny" new listings, leading to record-high prices for average properties. Meanwhile, "stale" listings (on market 45+ days) are being ignored, despite having motivated sellers who are terrified of Tuesday's rate decision.
Additional Context (KPMG Jan 2026):
• National house prices rose 8.6% in 2025 (strongest since 2021)
• Net housing supply forecast to fall 30% short of government targets
• Housing momentum accelerated dramatically in 2025H2, with some cities recording 60-76% of their annual growth in just the last 6 months
• Median house now 8.9x average income (up from 6.6x five years ago)
The opportunity
While everyone fights over fresh listings at 20+ bidders per auction, properties that have been sitting for 6+ weeks are essentially invisible. These sellers are watching the calendar and sweating the RBA meeting. They'll negotiate.
Key Takeaways for This Week
If you're planning to buy in the next 7 days:
✓ Verify your DTI ratio and understand if you're affected by the 20% cap
✓ Confirm your pre-approval is current with your broker
✓ Understand your borrowing capacity at different rate scenarios
✓ Have a clear maximum bid that includes a safety buffer
✓ Know that Tuesday's RBA decision could affect future borrowing, not your existing approval
