Investor loans surge, putting pressure on RBA and housing affordability | March 2, 2026

Australia’s central bank is facing mounting pressure to rein in lending to property investors, a move that could cool the nation’s housing market and potentially alleviate the need for further interest rate hikes. New data reveals a surge in speculative investment, particularly in affordable housing, squeezing first-time buyers and contributing to inflationary pressures. The Reserve Bank of Australia (RBA) has been walking a tightrope, attempting to curb inflation although maintaining employment, but some economists argue that stronger regulatory oversight of investor lending could have prevented the recent need to increase interest rates.

The latest figures, released by the RBA on Friday, show that credit growth to property investors has accelerated to its fastest pace since late 2015, rising 8.9 per cent over the past 12 months. This contrasts sharply with the 5.3 per cent growth rate recorded a year ago, before the RBA began cutting interest rates. While credit growth to owner-occupiers has also increased, it has done so at a slower pace, rising from 5.7 per cent to 6.1 per cent. This divergence highlights the significant role investors are now playing in driving up property values.

Investor Appetite and Regulatory Response

The Australian Prudential Regulation Authority (APRA), the nation’s banking regulator, introduced new rules on February 1 aimed at curbing excessive risk-taking in the mortgage market. These rules limit the proportion of new lending that can be allocated to borrowers with debt-to-income ratios exceeding six times. However, APRA initially anticipated that these measures would have a limited impact on investor activity, as few major lenders were expected to exceed the new threshold. The recent surge in investor lending suggests that this assessment may have been overly optimistic.

The increase in investor activity is particularly pronounced in certain markets. Perth and Brisbane have experienced the most significant price growth in February, with dwelling values rising by 2.3 per cent and 1.6 per cent respectively. Perth’s median house value has jumped by over 20 per cent in the past year, reaching $1.03 million, while Brisbane’s median house value has increased by 16.7 per cent to $1.175 million. In contrast, Sydney and Melbourne have seen more modest price movements, with values easing by 0.2 per cent in February. The number of homes for sale in Sydney and Melbourne has also increased, potentially contributing to the slowdown in price growth.

The Role of First Home Buyers

The surge in investor lending is exacerbating affordability challenges for first-time buyers. While the number of loans taken out by investors to purchase existing properties has soared by 25 per cent since February last year, the number of mortgages taken out by first-time buyers has increased by only 11 per cent over the same period. This disparity is driving up competition for entry-level homes, making it increasingly difficult for first-time buyers to enter the market.

Data from Cotality, released on Monday, further supports this trend. The research indicates that demand for affordable housing remains strong, with values for Sydney’s cheapest homes increasing by 0.8 per cent in February, while values for the most expensive properties fell by 0.9 per cent. This suggests that investors are increasingly targeting lower-priced properties, further squeezing first-time buyers.

Economic Implications and the RBA’s Dilemma

Independent economist Saul Eslake argues that the strong investor response to last year’s interest rate cuts has created a problem for the RBA and its efforts to control inflation. He suggests that if APRA had taken more decisive action, such as limiting interest-only loans – a popular option among investors – the RBA may not have needed to raise interest rates. “If APRA had done that, then the increase in interest rates may have been averted,” he told this masthead.

The RBA’s own analysis confirms the growing concern about investor lending. In the minutes of its recent monetary policy meeting, the bank noted that housing credit had “picked up noticeably” and was being driven by a “pick-up in investor credit.” The bank also acknowledged that stronger-than-expected real household incomes and wealth, fueled by rising property prices, had contributed to an unexpected increase in household spending. This wealth effect is a key concern for the RBA, as it can exacerbate inflationary pressures.

Capital Gains Tax and Investor Incentives

The issue is further complicated by the debate surrounding Australia’s capital gains tax (CGT) concession. Critics argue that the 50 per cent discount on CGT incentivizes property investment and allows investors to outbid first-time buyers. Former Treasury Secretary Ken Henry recently testified before a Senate inquiry, stating that the concession had personally affected his family and should be reformed. “There would be tens of thousands, if not hundreds of thousands if not millions of parents in Australia who could tell the same story – stories of standing at an auction, seeing their kids – potential owner-occupiers – being out-bid by investors,” he said.

The current CGT rules, established in 1999, allow investors to reduce their taxable profit from the sale of an asset by 50 per cent if the asset is held for more than 12 months. This concession is intended to encourage long-term investment, but critics argue that it disproportionately benefits wealthy individuals and contributes to housing affordability issues. The House of Representatives Standing Committee on Tax and Transfer is currently examining the operation of the CGT discount.

What’s Confirmed and What Remains Unclear

Confirmed: Investor lending is increasing at a rapid pace, outpacing growth in owner-occupier lending. This trend is particularly evident in Perth and Brisbane, where property values are rising sharply. The RBA is concerned about the impact of investor lending on inflation and household spending. APRA’s recent regulatory changes have not yet had a significant impact on investor activity.

Unclear: The extent to which APRA will tighten lending standards further. The likelihood of further interest rate hikes by the RBA. The potential impact of changes to the CGT concession on property investment. The long-term sustainability of the current housing market boom.

Looking Ahead: Potential Regulatory Adjustments

The RBA and APRA are closely monitoring the situation and are likely to consider further measures to cool the property market if investor lending continues to accelerate. Potential options include tightening lending standards, increasing capital requirements for banks, or introducing macroprudential policies specifically targeting investor lending. The effectiveness of these measures will depend on a variety of factors, including the overall economic climate and the responsiveness of investors to regulatory changes. The debate over the CGT concession is also likely to continue, with potential implications for the future of property investment in Australia. Fitch Ratings recently affirmed Atlanta, GA’s IDR at ‘AAA’, demonstrating a focus on financial stability which may influence similar assessments in Australia.

The interplay between monetary policy, regulatory oversight, and fiscal incentives will be crucial in determining the future trajectory of the Australian housing market. Navigating these complexities will require careful consideration of the potential trade-offs between economic growth, inflation control, and housing affordability.
