RBA Rate Decision May 2026: What It Means for Your Mortgage

The Reserve Bank of Australia cut the official cash rate by 25 basis points in May 2026, bringing it to 3.85% — and if you've got a mortgage, you're right to want to know what it means for your hip pocket. Here's the full breakdown: what the RBA did and why, how much your repayments could drop, which lenders are passing on the cut, and whether you should be fixing your rate right now.

What Did the RBA Actually Decide?

At its May 2026 meeting, the RBA Board voted to lower the cash rate target from 4.10% to 3.85%. This is the second cut of the current easing cycle, following the February 2026 cut that moved the rate from 4.35% to 4.10%.

In its statement, the Board cited continued easing in underlying inflation — which has now returned to the 2-3% target band — alongside softer-than-expected GDP growth and a labour market that, while still tight, has shown signs of cooling. The language was cautious: the Board emphasised it remains "data dependent" and is not pre-committing to further cuts.

Markets were split heading into the meeting, with some economists expecting the RBA to hold given persistent services inflation. The decision to cut reflects growing confidence that inflation is under control without inflation expectations becoming unanchored.

How Much Will Your Repayments Drop?

The maths depends on your loan size, remaining term, and whether your lender passes on the full cut. On a standard 25-year variable rate mortgage, a 25 basis point reduction saves roughly $16 per month for every $100,000 of outstanding loan balance.

Monthly Savings by Loan Size (Full 0.25% Cut Passed On)

Loan Balance	Monthly Saving	Annual Saving	Remaining Loan Life Saving*
$400,000	~$64/month	~$768/year	~$9,600 (25yr)
$500,000	~$80/month	~$960/year	~$12,000 (25yr)
$600,000	~$96/month	~$1,152/year	~$14,400 (25yr)
$800,000	~$128/month	~$1,536/year	~$19,200 (25yr)

*Approximate. Assumes consistent rate and minimum repayments. Actual savings vary with loan type, offset accounts, and extra repayments.

Keep in mind: these figures assume your lender passes on the full 0.25% cut. Not all do — and the timing matters too. Check your lender's announcement carefully.

Which Banks Are Passing On the Full Cut?

The major banks moved quickly after the RBA announcement. Here's where each of the Big Four stands:

• Commonwealth Bank (CBA): Passed on the full 0.25% cut. New variable rates effective from May 23, 2026. CBA's standard variable rate now sits at 6.14% p.a. (comparison rate 6.16%).
• NAB: Passed on the full 0.25% cut. Effective May 21, 2026. NAB's variable rate: 6.09% p.a. for owner-occupiers paying principal and interest.
• ANZ: Passed on the full 0.25% cut. Effective May 22, 2026. ANZ's variable rate: 6.19% p.a.
• Westpac: Passed on the full 0.25% cut. Effective May 23, 2026. Westpac's variable rate: 6.24% p.a.

Non-bank lenders and smaller mutuals are generally following suit, though timing varies. If you haven't received a notification from your lender, check your online banking or call them directly — the cut should flow through within 2-3 weeks of the RBA decision.

Should You Fix Your Rate Now?

This is the question everyone's asking, and there's no clean answer — but here's the honest framework.

The Case for Staying Variable

If you believe the RBA has more cuts to come (markets are currently pricing in a further 1-2 cuts before end of 2026), staying variable means you continue to benefit from each reduction automatically. Variable loans also give you more flexibility: offset accounts, redraw facilities, and the ability to make extra repayments without penalty are all standard on variable mortgages.

With the cash rate at 3.85% and some economists forecasting a terminal rate of around 3.35-3.60%, there's a reasonable argument that you're better off staying variable and riding the cycle down.

The Case for Fixing

Fixed rates from the major banks currently cluster around 5.49-5.79% for 1-2 year terms — which is lower than most standard variable rates after the May cut, but only by a small margin. If your priority is certainty (you're buying in the next year, or cash flow planning is critical), a 1 or 2-year fix could make sense.

However, be cautious about fixing for 3+ years. If the RBA continues cutting, you could end up locked into a rate well above where the market lands. And fixed loans come with break costs if you need to exit early.

The Split Loan Option

Many borrowers split their loan — fixing a portion (say 50%) for payment certainty while keeping the rest variable to benefit from further cuts. This is a legitimate hedging strategy, especially for larger loans. Talk to your broker about the optimal split for your situation.

Best Variable Rate Mortgages Right Now

The most competitive variable rates in the market following the May 2026 cut are coming from online lenders and challenger banks, not the majors. Here's a snapshot of the market:

• Reduce Home Loans (Rate Slasher): ~5.59% p.a. variable (comparison rate 5.61%) — consistently competitive, online-only, offset available
• Athena Home Loans: ~5.64% p.a. variable — no fees, automatic rate reductions as you pay down LVR
• uBank: ~5.69% p.a. variable — 100% offset, strong app, backed by NAB
• ING Orange Advantage: ~5.74% p.a. variable — 100% offset, good for everyday banking integration
• Big Four average: ~6.10-6.24% p.a. variable — significantly higher; the loyalty premium is real

The gap between the major banks and the most competitive online lenders is still significant — often 0.40-0.60%. On a $600,000 loan, that's $144-$216 per month in unnecessary interest. That's the real story here: the RBA cut matters, but where your rate sits relative to the market matters more.

Is Now a Good Time to Refinance?

If you haven't refinanced in the last 2-3 years — and especially if you're on a major bank's standard variable rate — the answer is almost certainly yes.

Here's the quick test: if your current rate is above 6.00% and you have at least 20% equity in your home, you should speak to a mortgage broker immediately. The savings are real and the process is more streamlined than ever — most refinances can be completed in 4-8 weeks, and a good broker will handle the paperwork.

When Refinancing Makes Sense

• Your rate is more than 0.50% above the best available in the market
• You have at least 20% equity (to avoid LMI on the new loan)
• You have a clean repayment history for the past 12 months
• You're not planning to sell in the next 12-18 months
• You don't have a fixed rate with large break costs attached

When to Hold Off

• You're mid-fixed-term and break costs would eat the savings
• Your LVR is above 80% (you'd trigger Lenders Mortgage Insurance)
• You've recently changed jobs or your income situation is in flux
• You plan to sell within 12 months

What About Savings Accounts?

The flip side of a rate cut is always savings accounts. The same day the RBA cut, the major banks began trimming their savings rates. If you're earning interest on a high-interest savings account or term deposit, expect your rate to drop by a similar 0.25%.

The best savings rates in the market (bonus rate accounts with conditions) were sitting around 5.10-5.25% before the cut, and will likely settle around 4.85-5.00% in the coming weeks. Term deposit rates have already been moving lower in anticipation of the cut.

If you have a large cash holding and are focused on returns, this is a good moment to lock in a 6-12 month term deposit at current rates before they fall further.

What Comes Next for the RBA?

The next RBA meeting is scheduled for July 2026. Market pricing (as of late May) suggests roughly a 55% chance of another 25 basis point cut at that meeting, taking the cash rate to 3.60%. A further cut later in 2026 is also possible if inflation remains contained and growth stays soft.

However, the RBA has been clear that it is not on a pre-set path. If inflation proves stickier than expected — particularly in services and housing-related components — the Board could pause. The labour market, wages growth data, and quarterly CPI prints will be the key inputs.

For mortgage holders, the most likely scenario is another 1-2 cuts over the next 12 months — meaning variable rate borrowers who stay the course should see further relief. But "likely" is not "certain," and your personal cash flow needs should drive your fixed vs variable decision more than rate predictions.

Bottom Line

The May 2026 RBA cut puts real money back in mortgage holders' pockets — up to $128/month on an $800k loan if your lender passes it all on. The Big Four have all moved quickly to pass on the full cut this time, which is good news.

But the bigger opportunity here isn't the 0.25% cut — it's the 0.40-0.60% you might be leaving on the table by staying with a major bank when competitive online lenders are sitting well below them. If you haven't reviewed your mortgage in the last 12 months, do it now. The market is in your favour.

Frequently Asked Questions

When does the rate cut take effect on my mortgage?

Each lender sets their own effective date, but most major banks implement RBA cuts within 2-3 weeks of the announcement. Check your lender's website or call them to confirm. Some lenders apply changes automatically; others require you to confirm your new repayment amount.

Will my repayments automatically drop or do I need to contact my lender?

For principal-and-interest variable loans, most lenders automatically reduce your repayment amount. For interest-only loans, the repayment reduces automatically. For offset account users, the benefit flows through as a lower interest charge each month. If your repayments don't change within 3-4 weeks of the RBA announcement, contact your lender.

Should I keep my repayments the same and pay off faster?

If you can afford to, yes. Keeping your repayments at their pre-cut level while rates fall is one of the most effective strategies for paying down your loan faster. Every extra dollar reduces your principal, reducing future interest charges. Your lender won't do this automatically — you'll need to either keep your direct debit at the old amount or set up an additional repayment.

How does this cut affect fixed rate loans?

It doesn't directly — fixed rate loans are locked in for the duration of their term. However, the cut does affect where fixed rates are being priced for new borrowers, and it will affect your rate when your fixed term expires and you roll onto a variable rate or re-fix.

Is it worth switching to a fixed rate now?

Only if certainty matters more to you than maximising savings. Fixed rates are currently slightly below standard variable rates from the majors, but online lenders' variable rates are often lower than available fixed rates. If you're comfortable with variable and can absorb some rate movement, staying variable gives you more flexibility and likely lower rates over the next 12-18 months if the RBA continues cutting.
