Personal credit growth reached 5.1% in the year to August 2026, according to the Reserve Bank of Australia's Financial Aggregates release published on 30 September 2026. That is the fastest annual pace for personal credit in the RBA's growth table since May 2008, and it arrived in the same month the cash rate target was lifted to 4.60%. For anyone weighing up a car loan or personal loan, the figures are a useful backdrop: more households are borrowing outside their home loans, and lenders are assessing those applications in a higher rate environment.
This article sets out what the RBA data shows, what it does not show, and the practical points car loan applicants may want to consider before they apply.
Quick answer: what the August 2026 personal credit growth figures show
Personal credit rose 0.7% in August 2026, after 0.5% in July, and was 5.1% higher than a year earlier. A year before, in August 2025, annual personal credit growth was 4.0%. Total credit across housing, personal and business lending grew 8.4% over the year, up from 7.2% in August 2025. All of these growth rates are seasonally adjusted and adjusted for breaks in the series.
The headline numbers from the RBA
The RBA's Financial Aggregates summary for August 2026 reported:
- Total credit: up 0.6% in the month and 8.4% over the year.
- Housing credit: up 0.4% in the month and 7.3% over the year, compared with 6.1% a year earlier.
- Personal credit: up 0.7% in the month and 5.1% over the year, compared with 4.0% a year earlier.
- Business credit (lending to non-financial businesses): up 0.9% in the month and 10.9% over the year.
Within housing, the RBA's growth table shows owner-occupier credit rose 0.5% in August and 6.2% over the year. Investor housing credit rose 0.3% in the month, and its annual pace eased to 9.6% from 10.4% in June 2026.
Why personal credit growth matters to car loan applicants
The RBA splits total credit into housing, personal and business lending. Personal credit sits outside home loans and business lending, which is why people looking at a car loan or personal loan tend to watch it. Faster growth means more borrowing is building up in that part of household balance sheets.
That matters at the individual level for a simple reason: when you apply for a car loan, the lender looks at your existing debts as well as the new loan. ASIC's guidance on responsible lending says credit licensees must make reasonable inquiries about a consumer's financial situation, take reasonable steps to verify it, and assess whether the credit contract is not unsuitable. Moneysmart notes that lenders may say no if you have other debts that reduce your capacity to repay.
If you have added a personal loan, a larger credit card limit or a buy now, pay later account over the past year, those commitments generally form part of the picture a lender sees. Our guide to how buy now, pay later can affect a car loan application explains why limits and repayment history can matter as much as balances.
Borrowing growth and a 4.60% cash rate
The August figures cover the month before the RBA's Monetary Policy Board raised the cash rate target by 0.25 percentage points to 4.60%, effective 30 September 2026. Personal credit kept growing while rates were already elevated, and the RBA's next decision is due after its meeting on 2 and 3 November 2026.
Higher rates generally flow into the buffers lenders apply when they test whether repayments are affordable. For car loan applicants, that can mean a smaller margin between what a lender will approve and what you would like to borrow. Our explainer on why car loan rates do not move one for one with the cash rate covers how lenders price personal and car lending differently from home loans, and the RBA minutes for September 2026 set out why the Board moved.
What the data does not tell you
The Financial Aggregates are a broad, economy-wide measure. A few limits are worth keeping in mind:
- The RBA notes its credit aggregates measure credit provided by financial institutions operating domestically, and do not capture cross-border or non-intermediated lending.
- The release reports growth rates, not the reasons people are borrowing. It does not say how much of the increase is car finance, credit cards or other personal lending.
- The RBA says levels of credit are not adjusted for series breaks, and growth rates should not be calculated from the levels data. The growth figures quoted here come directly from the RBA's tables.
So the data is a signal about the overall direction of household borrowing, not a forecast of how any one lender will treat your application.
How car loan applicants can respond
Rising personal credit across the economy does not change your own application, but it is a reminder to tidy up your side of the ledger before you apply. Some practical steps:
- List every commitment. Include car loans, personal loans, credit card limits, buy now, pay later accounts and any home loan. Our guide to what lenders check on your bank statements shows how these commitments can appear.
- Review unused credit limits. Lenders often consider the limit on a credit card rather than the balance, so a card you rarely use can still reduce what you can borrow.
- Check your credit report. Moneysmart says you can get a free copy from a credit reporting body every three months. Errors are worth fixing before a lender sees them.
- Avoid scattered applications. Moneysmart notes each credit application is recorded on your credit report, and too many in a short time can lower your credit score.
- Test the repayment. Use our car loan calculators to see how the repayment changes with the loan amount and term, and compare it with your budget.
If you already hold more than one loan, it may also be worth reading our explainer on how car loan repayments are calculated so you can see how term and rate change the total cost.
Personal credit growth and the wider household picture
Personal credit growth sits alongside other recent data on households. The ABS reported household debt rose in the June quarter, mostly through home loans, which we covered in household debt rose $73.5 billion in the June quarter. Fixed home loan rates also moved above variable rates in August, covered in our article on fixed home loan rates rising above variable.
Taken together, the picture is one of households carrying more debt at higher rates. That does not mean car finance is unavailable, but it does mean the application itself deserves care.
What to watch next
The RBA's schedule lists the next Financial Aggregates release, covering September 2026, for 30 October 2026, with the Statement on Monetary Policy due on 3 November 2026. Those two releases will show whether personal credit growth held its pace and how the Board views household borrowing after the September increase.
Compare before you commit
If you are planning a car purchase, compare the comparison rate and fees across lenders rather than the advertised rate alone. Our current car loan rates page and lender profiles are a starting point, and the car loans page explains how Loanseekers can help you compare options.
