Should You Fix Your Home Loan in 2026 After the RBA Rate Hikes?

The decision borrowers are facing

After three RBA rate rises in 2026, a lot of borrowers are asking the same question: should I fix my home loan now?

The RBA cash rate target is 4.35%, effective 6 May 2026. The increases in February, March and May have pushed mortgage stress back into the conversation and made fixed rates feel tempting again.

But fixing is not just a bet on where rates go next. It is a trade-off between certainty and flexibility.

A fixed rate can protect your budget. A variable rate can preserve offset access, extra repayment flexibility and easier refinancing. A split loan can sit between the two.

The right answer depends less on your rate forecast and more on your cash flow, savings habits and plans for the next few years.

What the RBA decision changes

The cash rate is not your mortgage rate, but it strongly influences lending and deposit rates across the economy.

When the cash rate rises, variable mortgage rates usually rise too, although lenders still set their own pricing based on funding costs, competition, credit risk and customer strategy.

That means borrowers should not assume every lender will price the same way. ASIC MoneySmart notes that there can be large differences between variable home loan rates on the market, so checking your loan against current offers is still worthwhile.

Before deciding to fix, compare your current rate, the best variable rate you can negotiate, and available fixed rates over the period you actually expect to keep the loan.

Use the Loan Comparison Calculator to compare total cost, not just the headline rate.

What a fixed rate gives you

A fixed rate gives repayment certainty for a set period, usually one to five years.

That can be valuable if:

• Your household budget is tight.
• You are about to start parental leave.
• You are moving from two incomes to one.
• You are self-employed and want stability.
• You would struggle with another rate rise.
• You prefer knowing the exact repayment.

Certainty has value. If a surprise increase would force you to cut essentials or rely on credit cards, fixing part or all of the loan can be sensible even if it is not the cheapest possible outcome.

What you give up when you fix

Fixed loans usually come with restrictions.

Depending on the lender and product, you may face:

• Limited or no full offset account.
• Caps on extra repayments.
• Break costs if you repay, refinance or sell during the fixed term.
• Less benefit if variable rates fall.
• A revert rate when the fixed term ends.

These are not minor details. For some borrowers, losing offset access can cost more than the rate saving from fixing.

Why offset access can change the answer

An offset account reduces the loan balance on which interest is calculated while keeping your cash accessible.

If you have meaningful cash savings, a variable loan with a full offset can be powerful.

For example, if you have a $700,000 variable loan and keep $60,000 in offset, interest is calculated on $640,000 instead of $700,000. At a rate around the mid-6% range, that offset balance can save thousands of dollars a year in interest.

If fixing means giving up the offset, you need to compare:

• The fixed-rate saving.
• The lost offset benefit.
• Any extra repayment limits.
• The likelihood you will need access to the cash.

This is why borrowers with large offset balances often split the loan rather than fixing everything.

Break costs are the risk people forget

Break costs can apply if you exit a fixed loan early.

This can happen if you:

• Sell the property.
• Refinance.
• Repay a large amount beyond the permitted cap.
• Switch products before the fixed term ends.

ASIC MoneySmart warns borrowers to check fixed-rate break fees before switching home loans. The cost depends on lender policy, wholesale rate movements, remaining fixed term and loan balance.

The key point is practical: do not fix for three years if there is a real chance you will sell, refinance, separate, relocate, renovate with a major cash injection, or need to restructure the loan in year one.

When variable can be the better choice

A variable rate may suit if:

• You want full offset access.
• You plan to make large extra repayments.
• You expect to refinance soon.
• You may sell in the next year or two.
• Your income is variable but your cash buffer is strong.
• You want to benefit quickly if rates fall.

Variable does not mean passive. A variable borrower should actively negotiate.

MoneySmart suggests asking your current lender for a better deal before switching. Lenders often reserve sharper rates for new customers unless existing customers ask.

When fixing can be the better choice

Fixing may suit if:

• Repayment certainty matters more than maximum flexibility.
• You have little or no offset balance.
• You are not planning to sell or refinance during the fixed period.
• You are comfortable with the fixed loan's extra repayment limits.
• Your budget would be exposed if rates rose again.
• The fixed rate is competitive against your negotiated variable option.

For many households, the emotional value of certainty is real. A technically cheaper variable loan is not helpful if every RBA meeting causes budget stress.

The split loan middle ground

A split loan divides the mortgage into fixed and variable portions.

For example:

• 50% fixed for repayment certainty.
• 50% variable with offset and extra repayment access.

This can work well when you want protection but do not want to give up all flexibility.

Common split strategies include:

• 70% fixed and 30% variable for higher certainty.
• 50% fixed and 50% variable for balance.
• 30% fixed and 70% variable for flexibility with some protection.

There is no perfect ratio. The right split depends on how much cash you keep in offset, how stable your income is, and how painful another rate rise would be.

A simple way to choose your split

Start with the amount you want to keep flexible.

If you have $80,000 in savings and expect to save another $2,000 per month, fixing the entire loan may waste the benefit of that cash.

You could keep a variable portion large enough to absorb your offset balance and expected extra repayments, then fix the rest.

For example, if your loan is $700,000 and you want $150,000 of flexibility, a $550,000 fixed portion and $150,000 variable portion may be more practical than an all-fixed loan.

This is not a recommendation. It is a modelling approach. The goal is to avoid fixing money that you already know you want to offset or repay quickly.

Do not compare rates without comparing fees

The lowest advertised rate is not always the cheapest loan.

Compare:

• Application fees.
• Annual package fees.
• Monthly fees.
• Offset account fees.
• Discharge fees.
• Break cost risk.
• Cashback conditions.
• Revert rates after a fixed period.

The comparison rate can help, but it has limits because it is based on a standard loan size and term that may not match your situation.

Use the Loan Comparison Calculator with your actual loan balance, term and fees.

Refixing when your fixed term ends

If your fixed term is ending in 2026, do not wait for the lender's automatic rollover.

Your action plan:

1. Ask your lender for the current fixed, variable and split options.
2. Ask for a retention discount on the variable option.
3. Compare at least two external lender offers.
4. Check whether refinancing costs outweigh savings.
5. Decide whether offset access matters more now than it did when you first fixed.
6. Avoid extending the loan term back to 30 years unless you intentionally want lower repayments now.

MoneySmart warns borrowers to be clear on the length of the new loan when switching, because a longer loan term can increase total interest even if the rate is lower.

Questions to ask before fixing

Before locking in a fixed rate, ask:

• Can I make extra repayments, and what is the cap?
• Is there a full offset, partial offset or no offset?
• What happens if I sell during the fixed term?
• How are break costs calculated?
• What variable rate will the loan revert to when the fixed period ends?
• Can I split the loan?
• Can I keep my offset against the variable portion?
• Are there package fees or annual fees?
• Can I redraw extra repayments?

If the lender cannot explain the restrictions clearly, slow down.

Bottom line

Do not fix your home loan just because rates have already risen. Fix because the structure suits your next few years.

A fixed rate may suit borrowers who need repayment certainty and do not rely heavily on offset or extra repayments.

A variable rate may suit borrowers with strong cash buffers, large offset balances, refinancing plans or uncertain life events.

A split loan may suit borrowers who want both protection and flexibility.

Before deciding, run three scenarios:

1. All variable.
2. All fixed.
3. A split loan.

Compare monthly repayments, total interest, fees, offset savings and the cost of losing flexibility.
