Seismic shift: two major banks hike fixed interest rates

September 08, 2025

Understanding the Impact of Rate Hikes

Recently, two major Australian banks announced significant hikes in their fixed interest rates. These moves are part of broader market shifts that are shaping home loans and borrowing costs across the country. As a trusted advisor with over 20 years helping international clients settle in Australia, I want to break down what this means for you—whether you’re a first-time buyer, investor, or refinancing a property.

What Are Fixed Interest Rates?

A fixed interest rate is a loan rate that remains unchanged for a specific period, often 1 to 5 years. This means your mortgage repayments stay the same, offering predictability. Fixed rates contrast with variable rates, which fluctuate with market conditions.

Why Are Banks Increasing Fixed Rates Now?

Recent hikes reflect the Reserve Bank of Australia’s (RBA) cautious monetary policy to curb inflation. When the RBA raises rates, lenders often follow suit to maintain their profit margins. In the past three months, leading banks such as Commonwealth Bank and ANZ announced increases of approximately 0.50% to 0.75% on their fixed-rate products.

What Do These Changes Indicate?

  • Market Uncertainty: Economic indicators suggest inflation may stay above target for longer.
  • Lender Strategy: Banks aim to manage risks in a rising rate environment.
  • Future Expectations: Markets anticipate further rate hikes if inflation persists.

How Do Rate Hikes Affect Borrowers?

For homeowners and investors, higher fixed interest rates mean increased monthly repayments. For example:

ScenarioOld Fixed RateNew Fixed RateMonthly Repayment (on $500,000 loan)
3-year fixed3.00%3.75%~$2,100
5-year fixed3.20%4.00%~$2,130

This mild increase sounds simple, but over the loan term, the difference can add up significantly.

Key Impacts:

  • Cost of Borrowing: Higher rates increase total interest payable.
  • Budget Planning: Borrowers need to reassess household budgets.
  • Refinancing Decisions: Fixed rate hikes may influence whether to lock in or wait.

What Should Borrowers Do Now?

While rate increases are discouraging for some, they also present opportunities:

  • Review Existing Fixed Deals: If your fixed term ends soon, compare new fixed rates versus switching to variable.
  • Consider Lenders: Different banks offer varying fixed rates. Shopping around can save thousands.
  • Assess Your Capacity: Make sure your borrowing comfort aligns with new repayment amounts.

Eligibility and Documentation Tips for Australian Mortgages

Whether you're a first home buyer, investor, or refinancing, certain documents are essential across all cases:

  • Proof of Income: Recent payslips, tax returns for self-employed, or overseas income statements.
  • Deposit Funds: Sources such as overseas savings, gift letters, or Australian savings accounts.
  • Identification: Passport, visa details (if applicable), and proof of residency.
  • LMI (Lenders Mortgage Insurance): Usually required if the deposit is less than 20%.
    Note: Some lenders now accept overseas credit history, subject to approval.

Important: To qualify, you often need your deposit to be genuinely saved and sourced, with no recent large deposits unless documented properly.

First-Time Buyers & International Clients

For newcomers, understanding the Australian property market and financial system is crucial. Here are some tips:

  • Check Your Visa Status: Most lenders require a temporary or permanent residence visa.
  • Foreign Income: When converting overseas earnings, use official exchange rates and ensure funds are legally sourced.
  • FIRB Approvals: Foreign Investment Review Board approval is mandatory for non-residents purchasing Australian property.

Common Barriers and How to Overcome Them:

  • High Deposit Requirement: Typically 5-20%. Consider family assistance or gifted deposits.
  • Credit History: Keep records of overseas credit or loan history. Some banks accept international data.
  • Processing Times: Allow extra time for documentation verification, especially for overseas applicants.

The Big Picture: How Will These Rate Changes Impact the Market?

Higher fixed rates may slow down property demand slightly, especially among first-time buyers. However, in the long term, rates tend to stabilize once the market adjusts. Investors might reconsider fixed vs. variable borrowing, balancing security against potential rate drops.

Expert Insight

As David Smith, CEO of the Australian Banking Association, states:
"They're adjusting to global economic pressures, and borrowers need to plan ahead. Fixed interest rate hikes are a reminder to consider your long-term financial position and seek tailored advice."

Bottom Line

The recent fixed-rate increases reflect broader economic shifts. For borrowers, understanding how these changes influence loan costs is essential to making smart financial decisions. Whether you're locking in now or waiting, knowing your options helps you navigate this seismic shift confidently.

Next Steps:

  • Review your current fixed loan terms.
  • Shop around with different lenders.
  • Consult with a mortgage broker for personalized advice.

And remember, in uncertain times, being well-informed makes all the difference. If you’re considering purchasing property in Australia—whether for investment or your new home—proper planning and expert guidance are your best tools.
