Top Safest Banks in Australia (2024)

No Australian bank has collapsed since Queensland Permanent Building Society in 1977. Through shocks like the Global Financial Crisis (GFC) and the Covid19 pandemic, Aussie banks have stood firm. It’s unlikely that any Australian Bank will collapse in the manner of Silicon Valley Bank in the US, for example, but if you prefer to err on the side of caution, small differences do make some institutions a slightly safer bet than others.

Why Australian Banks are so safe

Common Equity Tier 1 (CET1)Ratio

After the GFC, sweeping regulations were introduced across the globe to ensure banks didn’t behave quite so recklessly. CET1 requirements were introduced to ensure banks had the capital reserves to absorb unexpected shocks, like the housing crisis of 2008. The capital held by banks was broken down into several categories, with CET1 being the “highest quality of regulatory capital”, or the money that is on hand and readily available to absorb losses. CET1 capital doesn’t include customer deposits, because these are a liability for the bank rather than an asset.

Banks have to have a certain amount of CET1 capital (at least 4.5%) on hand as a percentage of its assets like loans and investments, so that if there is a surge in loss, there are the cash reserves on hand so the bank doesn’t collapse. If this threshold is breached, regulators will likely step in to ensure the bank improves its capital position.

The banks in Australia well exceed the 4.5% mark. The largest banks all exceed 10%, with Commonwealth Bank at 12.3% as of December 31 2023.

$250,000 Deposit Guarantee

Cash deposits in Australian Banks are guaranteed by the Federal Government under the Financial Claims Scheme (FCS). Introduced post GFC, the FCS covers any deposit balance up to $250,000 held in banks, building societies or credit unions. This covers every Authorised Deposit-taking Institution (ADI), and applies per account holder - keep in mind some banks share banking licences (ADI), for example CommBank and Bankwest.

The FCS covers transaction accounts, savings accounts, term deposits, offset accounts, and more other types of deposits. This also extends to policies with general insurers in the unlikely event that one of these financial institutions failed.

The guarantee means there is no need to pull your money out of the bank if you feel it is going under. This is to benefit the bank as well as they are less likely to be bled dry of deposits. Your money is guaranteed, keeping both you and the bank safe.

Lending standards

Regulators like APRA have responsible lending standards that banks need to abide by. For example, when assessing home loan applications, banks apply a 3% serviceability buffer to the interest rate the borrower will pay. If you’re applying for a loan at 6% p.a, you will only be approved if your lender is satisfied you would be able to repay the loan at 9% p.a.

Another one is the debt-to-income ratio, or DTI. Many banks have hard caps on their DTI ratios, and some are more conservative than others. At present many banks restrict lending if the debt is more than 7-times someone’s income. For example, if you earned $100,000 per year, a bank might be reticent to lend you more than $700,000.

This is to ensure banks aren’t giving out loans to people who present an unacceptable risk of defaulting at some stage during the loan term.

Which Australian Bank is the safest by credit risk?

Each year, news outlet Global Finance publishes its list of the safest banks in the world. This is based on long term foreign currency credit ratings, or the ability of banks to meet financial commitments in foreign currency. High ratings mean the international financial community see this bank as more reliable, and therefore more secure for depositors and investors. Global Finance used ratings from Moody’s, Standard and Poor’s (S&P) and Fitch to come up with the rankings.

According to Global Finance, the safest bank in Australia in 2023 was Commonwealth Bank. This list was unchanged from 2022.

As you can see, the big four have identical scores, all very strong indicating a very low credit risk. On the global rankings, Australia’s big four sit 35th-38th, while Suncorp also made the top 100, coming in at 86th.

Regions like Western Europe, North America and Asia had higher scores across the top ten banks, while Australia’s biggest banks are considered more secure than those of Latin America, Africa and Eastern Europe.

Across all nine banks, the credit scores meet the ‘Investment Grade’ standard at all three credit agencies, except Fitch which did not assess Newcastle Mutual. This seems to validate the general consensus, from economists and politicians, that the Australian banking sector is secure.

In the aftermath of the collapse of the US based Silicon Valley Bank in 2023, Treasurer Jim Chalmers reassured Australia that its financial institutions were well positioned to deal with global challenges.

“[Australia’s] banks are well-regulated, well capitalised and highly liquid and are in a better position than most to deal with these disruptions,” he said.

Which Australian Bank is safest from hackers and scammers?

Bank collapse may be unlikely, but there are other areas of concern. In February 2016, hackers stole $81 million USD from the central bank of Bangladesh, while cyber attacks have also successfully stolen money in Russia.

The Australian Banking Association (ABA) is clear that the cybersecurity of Aussie banks needs to be continually updated to stay ahead of these kind of threats, protecting both the deposits and personal information of customers.

Scamming however is a different story. Australians lose billions of dollars each year to scams, which has seen institutions improve their infrastructure to better protect customers. In late 2023, every bank and credit union in Australia with an ADI licence signed an anti scam agreement, rolling out anti scam measures including improved warnings and payment delays.

At the end of the day, your bank account is only as secure as you make it. Practices such as not sharing your PIN, having a strong password, using 2-factor authentication, and not trusting calls or emails purporting to be from your bank demanding payment, can all go a long way in keeping your money safe.
