If you have a mortgage with an offset account, a recent offset account investigation by ASIC may have you wondering whether your account has actually been reducing your home loan interest. While offset accounts can be a powerful tool for saving money and paying off your mortgage faster, ASIC’s findings revealed that some borrowers may not have received the benefits they expected due to administrative errors and account linking issues.
Offset Account Investigation: What Every Homeowner Needs to Know
Offset accounts have become one of Australia’s most popular home loan features, helping borrowers reduce interest costs while maintaining easy access to their savings.
In fact, more than half of Australian home loans now include an offset account. For many homeowners, this feature has become an essential part of their mortgage strategy.
However, a recent offset account investigation conducted by the Australian Securities and Investments Commission (ASIC) uncovered issues affecting some borrowers, raising concerns about whether all offset accounts are functioning correctly.
The good news is that there are simple steps you can take to confirm your offset account is working as intended and helping you maximise your savings.
What Is an Offset Account and How Does It Work?
Before looking at the findings of the offset account investigation, it’s important to understand how offset accounts operate.
An offset account is a transaction account linked directly to your home loan.
Rather than earning interest like a traditional savings account, the balance in your offset account reduces the portion of your mortgage that lenders use to calculate interest.
For example:
- Home loan balance: $600,000
- Offset account balance: $50,000
Instead of charging interest on the full $600,000, your lender calculates interest on just $550,000.
This means:
- Less interest charged
- More of each repayment reduces your loan principal
- Potential savings of thousands of dollars over the life of your loan
- Because your repayments generally remain the same, the savings can add up significantly over time.
What the ASIC Offset Account Investigation Found
The recent offset account investigation was launched after the growing popularity of offset accounts across Australia.
Homeowners currently hold more than $349 billion in offset accounts, making them a major feature of the mortgage market.
ASIC reviewed offset account processes across eight major lenders:
- AMP Bank
- ANZ
- Commonwealth Bank
- Westpac
- Macquarie Bank
- ING
- HSBC
- Great Southern Bank (formerly Credit Union Australia)
Together, these lenders represent approximately 70% of Australia’s mortgage market.
During the review, ASIC identified several issues that prevented some borrowers from receiving the full benefits of their offset accounts.
The most common problem involved offset accounts that had been opened but never properly linked to a customer’s home loan.
This accounted for around 55% of all issues identified in the offset account investigation.
Without the correct link in place, borrowers may have believed their savings were offsetting mortgage interest when, in reality, they were paying interest on the full loan balance.
Another significant issue involved offset accounts that should have been established but were never opened correctly, representing around 22% of the cases reviewed.
Why These Offset Account Problems Matter
The issues uncovered through the offset account investigation can have a major financial impact over time.
Even a relatively small offset balance can generate meaningful savings when applied consistently over many years.
For example, a borrower maintaining a $30,000 to $50,000 offset balance could potentially save thousands of dollars in interest over the life of their loan.
If an offset account isn’t linked correctly, these savings may never be realised.
The borrower continues making normal mortgage repayments while unknowingly paying more interest than necessary.
This highlights why regular home loan reviews are so important.
Many homeowners assume everything is working correctly once their loan settles, but administrative issues can occasionally occur, particularly following loan changes or refinancing.
Which Borrowers Are Most at Risk?
According to ASIC’s findings, problems were more likely to occur after major changes to a home loan.
These situations included:
Refinancing a Home Loan
Refinancing can be a great way to secure a better interest rate or access improved loan features.
However, during the transition process, the connection between the home loan and offset account may not always transfer correctly.
End of a Fixed-Rate Period
Borrowers moving from a fixed-rate loan to a variable-rate loan may also face an increased risk of offset account issues.
In some cases, the offset feature may need to be reconnected or activated following the change.
Loan Restructures
Changes to loan products, account consolidations, or mortgage restructuring can occasionally affect linked accounts as well.
This is why homeowners who have recently changed lenders or loan products should perform a quick review to make sure their offset account remains active.
How to Check If Your Offset Account Is Working
Fortunately, confirming your offset account is functioning correctly is usually straightforward.
Check Your Online Banking
Log in to your banking app or internet banking portal and open your home loan account.
Look for sections such as:
- Offset Accounts
- Account Details
- Loan Settings
- Manage Accounts
You should see the account number of any linked offset accounts displayed within your loan information.
Review Your Home Loan Statement
Your mortgage statement may also show:
- Linked offset account numbers
- Daily balance calculations
- Interest calculations
- Details of how the offset balance was applied
Reviewing these details can provide reassurance that your offset account is operating correctly.
Contact Your Lender
If anything appears unclear, contact your lender directly and ask them to confirm:
- Whether the offset account is linked
- When it was linked
- Whether it is reducing the interest calculation on your loan
Speak With a Mortgage Broker
A broker can review your loan setup and help identify whether your mortgage is structured in the most effective way for your financial goals.
What Banks Are Doing to Fix the Issue
Following the offset account investigation, lenders have already paid more than $55 million in compensation to affected customers.
ASIC has also made it clear that lenders must strengthen their systems, improve processes, and reduce the likelihood of future offset account failures.
The regulator continues to monitor lenders closely and expects institutions to proactively identify and remediate impacted customers.
While industry representatives have stated that only a small number of accounts were affected relative to the total number reviewed, it’s still worth taking a few minutes to confirm your own account is working correctly.
Make Sure Your Mortgage Is Working for You
An offset account can be one of the most effective tools for reducing home loan interest and paying off your mortgage sooner.
