APRA Lending Policy in 2026: What Has Changed and What Borrowers Need to Know

APRA's Role and Approach to Australian Mortgage Regulation

APRA supervises authorised deposit-taking institutions (ADIs) — banks, credit unions and mutual banks — under the Banking Act 1959 and associated prudential standards. Its primary objective is financial system stability, not consumer protection (that is ASIC's domain). In the mortgage market, APRA uses both prescriptive standards (such as minimum capital requirements) and macroprudential tools (such as the serviceability buffer and lending limits) to manage systemic risk.

APRA's approach is countercyclical — it tends to tighten standards when credit is growing rapidly and household leverage is increasing, and may ease standards when conditions moderate. This means APRA settings change over time, and keeping up to date with current standards is important for borrowers, lenders and advisers.

Key APRA Mortgage Policy Settings as of 2026

The 3% serviceability buffer: APRA requires all ADIs to assess whether borrowers can service their loan at a minimum of 3% above the loan's actual rate. This has been in place since October 2021 and remains unchanged in 2026. At 6.0% variable, the assessment rate is 9.0%. At 5.8% fixed, the assessment rate is 8.8%.

Interest-only lending limits: APRA does not currently have a hard cap on the proportion of interest-only loans in lenders' books (the 30% system-wide cap introduced in 2017 was removed in 2019). However, APRA monitors IO lending and requires lenders to apply enhanced scrutiny to IO applications, including assessing affordability at the revert-to-P&I repayment. Investor lending: APRA's 10% annual growth cap on investor lending (in place 2014–2018) has not been reinstated. Lenders make their own risk-based decisions on investor loan volumes within APRA's general risk management framework.

• ✓3% serviceability buffer — assessment rate = loan rate + 3% (unchanged)
• ✓Interest-only lending — no system-wide cap, but enhanced scrutiny applies
• ✓Investor lending — no growth cap currently, lender-managed within risk frameworks
• ✓LVR limits — no Australian-equivalent of NZ-style LVR restrictions currently in place
• ✓Lending concentration — APRA monitors geographic and sector concentration risks

How APRA Policy Affects What You Can Borrow in Practice

The most direct APRA impact on individual borrowers is the 3% serviceability buffer, which reduces borrowing capacity by approximately 20–25% versus assessment at the actual loan rate. This is by design — APRA intends this as a precautionary measure to ensure borrowers can absorb rate increases. For most mainstream home loan applicants at ADIs, the buffer is the primary APRA constraint.

For borrowers seeking non-bank lender products (ASIC-regulated, not APRA-regulated), the buffer requirement does not legally apply — though most responsible non-bank lenders apply their own serviceability stress-testing. Non-bank lenders may use a 2% or 2.5% buffer, which can increase maximum borrowing amounts. This is one legitimate reason to use a non-bank lender in certain circumstances.
