APRA's Risk Weight Cuts Could Free Up Lending for Home Builders

APRA is consulting on capital changes that could reduce banks' lending costs for residential developers and boost housing supply from April 2027.

Australia's banking regulator has opened consultation on changes that could expand the capacity of banks to lend to residential developers — with potential flow-on effects for housing supply and borrowing conditions.

The Australian Prudential Regulation Authority (APRA) is proposing to lower standardised risk weights in three key lending categories, with the most significant for housing being a change to residential land acquisition, development, and construction (ADC) lending. Australian Broker reported on the proposals, which form the first of three workstreams in a broader capital and liquidity reform package announced in March 2026.

APRA intends to finalise credit risk capital changes in the second half of 2026, with a proposed effective date of 1 April 2027.

What APRA Is Proposing

Risk weights are a regulatory mechanism that determines how much capital a bank must hold against each category of loan it makes. A higher risk weight means more capital is tied up per dollar lent — and that increases the cost of that lending for the bank and, ultimately, the borrower. Lower risk weights free up capital that can be deployed elsewhere.

APRA Chair John Lonsdale framed the proposals as a calibration exercise rather than any loosening of prudential standards.

"By making our risk weights for some categories of corporate lending more granular and risk-sensitive, we believe we can improve the efficiency of the capital framework without compromising core prudential objectives," Lonsdale said. "By reducing the amount of capital banks need to hold against these categories of loans, it should give banks greater capacity to deploy released capital in a manner that supports broader economic outcomes."

APRA confirmed the full package is expected to be cost neutral overall — meaning the total capital held by the banking system does not change, only how it is distributed across lending types. The regulator also noted that, despite relatively high capital requirements by international standards, bank returns in Australia are broadly in line with global peers, capital does not currently appear to constrain lending, and credit remains readily available. These proposals are therefore designed to improve efficiency, not to address any existing credit crunch.

The three proposed changes are as follows.

**Residential land, development, and construction lending:** APRA proposes lowering the qualifying pre-sales requirement for residential developments from 100 per cent of total debt to 50 per cent. Developments meeting this lower threshold would access a lower 100 per cent risk weight, rather than the higher 150 per cent risk weight that currently applies to ADC loans that do not qualify. For build-to-let structures specifically, APRA proposes replacing the pre-sales requirement with a new pre-lease requirement. Both changes are expected to reduce the cost of capital for residential development and expand bank capacity to support housing supply.

**High-quality unrated corporate lending:** APRA proposes introducing a new 65 per cent risk weight for high-quality unrated borrowers graded equivalent to an A- credit rating or better — down from the current 85 per cent applied to investment grade lending. APRA expects this could lower the cost of credit for stronger unrated businesses, with flow-on effects for any borrower financing business growth or property-related corporate structures.

**Large domestic public infrastructure:** APRA proposes applying domestic public sector entity risk weights to eligible large public infrastructure operators. This is the least directly relevant for most residential borrowers but could improve credit conditions in large-scale project finance.

What It Means for Home Buyers and the Market

For everyday home buyers, the ADC lending change carries the most practical significance. If banks can lend to residential developers at a lower capital cost, more development projects become commercially viable — and that eventually means more new homes entering the market.

Australia's housing supply shortfall has multiple drivers. Planning delays and construction costs dominate the conversation, but the cost and availability of development finance also shapes what gets built. High pre-sales requirements have historically acted as a barrier, preventing some otherwise viable projects from proceeding and slowing the pipeline of new stock.

By lowering the qualifying pre-sales threshold from 100 per cent to 50 per cent of total debt, APRA is proposing to bring more residential developments within reach of mainstream bank financing at more competitive pricing. This matters for [first-home buyers](/home-loans/first-home-buyer) waiting on new supply to enter their target suburbs, and for investors evaluating off-the-plan developments.

It is important to be clear about what these changes are not: they are not a rate cut, and they will not lower your variable home loan rate in the near term. The effective date is 1 April 2027 and consultation is still open. What they represent is a measured policy signal that APRA sees scope to make the banking system's capital settings more efficient in a way that could, over time, support new housing construction.

What Borrowers Should Do in the Meantime

These proposals will not affect your home loan rate today. But they are worth understanding for anyone making medium-term property decisions.

If you are a **first-home buyer** weighing up new builds versus established properties, the direction of APRA's reform is a positive signal for housing supply over time. Understanding your [borrowing power](/calculators/borrowing-power) under today's settings is the most useful first step right now.

If you are an **investor** considering a development-linked or off-the-plan purchase, the regulatory direction is constructive — but current credit settings still apply. A broker who understands [investor home loans](/home-loans/investor) can map out what's available now.

If your focus is **refinancing**, APRA's capital proposals have no near-term impact on variable rates. What matters is whether your current loan remains competitive — a [refinance comparison](/home-loans/refinance) can answer that quickly.

APRA's risk weight reforms are a measured step toward making the banking system more efficient. They will not fix the housing supply problem overnight, but lowering the financial cost of development lending is a step in the right direction for a market that badly needs new residential construction.
