S&P Warns Australia's 5% Deposit Scheme Could Backfire — What Borrowers Need to Know

S&P Warns 5% Deposit Scheme Could Backfire on Australia's Housing Market

S&P Global has issued a caution on Australia's popular Home Guarantee Scheme, warning that while the policy lowers the entry barrier for first home buyers, it may be creating new vulnerabilities in the mortgage market as interest rates remain elevated.

What the Scheme Offers

The Home Guarantee Scheme allows eligible first home buyers to purchase property with as little as a 5% deposit, with the federal government guaranteeing the gap to the standard 20% threshold. Borrowers avoid Lenders Mortgage Insurance (LMI) — a saving that can reach $20,000 or more on a median-priced property.

S&P's Core Concern

S&P's analysis points to a structural risk: borrowers entering with minimal equity have very little buffer if conditions shift. Specifically, the risk increases when:

• Property values decline, wiping out thin equity margins
• Interest rates stay high, stretching already-stretched repayment capacity
• Employment conditions worsen, reducing household income

With the ABS reporting CPI at 3.7% annually as of February 2026 and the RBA's next rate decision not due until 5 May 2026, the rate environment remains uncertain. S&P notes that high loan-to-value ratios have historically correlated with elevated default rates during periods of economic stress.

Who the Scheme Actually Serves — and Who It Doesn't

The scheme is designed for PAYG employees with stable, verifiable income. But a significant portion of Australians fall outside its eligibility:

• Self-employed borrowers whose income doesn't meet income cap or verification requirements
• New migrants and PR holders still building credit and employment history
• Business owners who structure income through dividends or distributions
• Borrowers seeking properties above price thresholds in major metro areas

For these borrowers, the scheme simply isn't available — regardless of their actual financial position.

Non-Bank Solutions for Borrowers Outside the Scheme

Non-bank lenders offer flexible pathways that don't depend on government guarantees. MPFG Capital's Alt Doc loan products, for instance, allow self-employed borrowers to verify income through BAS statements or accountant letters instead of payslips. Lending criteria is assessed holistically rather than against rigid PAYG-based templates.

For borrowers with a strong asset base but non-standard income, this approach can be more appropriate — and more accessible — than schemes designed for a narrower borrower profile.

Key Takeaway

The 5% deposit scheme offers genuine opportunity for eligible borrowers, but S&P's warning is a timely reminder that low-deposit lending carries real risk. Those who don't qualify should be aware that non-bank alternatives exist and may better suit their circumstances.
