Interest Rate Forecast Australia 2026 — RBA Cash Rate Now 4.35%, Heading to 4.7% by December (Big-Four Predictions)

By , Founder & Editor·14 May 2026·Last updated 18 May 2026

Where Australian interest rates are heading: cash rate at 4.35% after the 5 May 2026 RBA hike, big-four banks forecasting 4.6–4.85% by December, RBA central outlook 4.7% peak. What each 0.25% move costs you (~$75/month per $500K loan) and what FHBs should do now.

Updated 14 May 2026 — 9 days after the RBA's May rate decision. Few numbers affect Australian first home buyers more than the RBA cash rate. Every 0.25% move is roughly $75 a month on a $500,000 loan — which means a half-percent shift either way can decide whether you can comfortably afford a home or whether it stretches you too far. This guide covers where the cash rate sits right now (4.35% after the 5 May hike), what the major banks and the RBA itself are forecasting for the rest of 2026, and what first home buyers should actually do about it.

Because the RBA meets every six weeks and the forecasts move with every meeting, treat this page as a current snapshot — NestPath updates it after each RBA decision. This page was last fully refreshed after the 5 May 2026 meeting.


Current RBA Cash Rate — May 2026

The RBA cash rate target is currently 4.35%, effective from 5 May 2026. The Reserve Bank's Monetary Policy Board voted (eight-to-one) to lift the cash rate by 25 basis points at the May meeting, taking it back to the November 2023 cycle peak. The Board's reasoning was straightforward: headline inflation has picked up materially since the second half of 2025, capacity pressures have not eased, and the recent run-up in global fuel and commodity prices (off the back of Middle East conflict) is already feeding into Australian inflation expectations.

This brings the post-2022 RBA trajectory into clearer focus. The rba interest rate path over four years has been a round trip rather than a straight line:

  • 2022–2023: the RBA lifted the cash rate from 0.10% in May 2022 to 4.35% in November 2023 — 13 increases across 18 months, the fastest tightening cycle in Australian history.
  • 2024: the cash rate sat at 4.35% for the entire year as inflation slowly came down from its 2022 peak.
  • February 2025: the first cut in four and a half years — 25 basis points down to 4.10% — as headline inflation returned inside the 2–3% band.
  • May 2025: another 25 bp cut to 3.85%.
  • August 2025: a further 25 bp cut to 3.60% — the low point of the easing cycle.
  • February 2026: the RBA lifted the cash rate 25 bp back to 3.85% after inflation reaccelerated and the labour market tightened again.
  • March 2026: a second 25 bp increase to 4.10%.
  • 5 May 2026: a third 25 bp increase to 4.35% — the rate you're paying today. Match for the late-2023 peak.

The practical takeaway: borrowers who entered 2026 expecting more cuts have absorbed 75 basis points of increases across three meetings. Borrowers who locked in fixed rates at the August 2025 low of 3.60% look very smart — they're insulated for the duration of their fixed term. Variable-rate borrowers on a $500,000 loan are paying roughly $225 more per month than they were in late 2025.

The RBA's next decision is scheduled for 16 June 2026. Market pricing as of mid-May 2026 implies the RBA pauses at 4.35% in June, with a roughly 35% probability of a further 25 bp hike. The RBA's own May 2026 Statement on Monetary Policy assumes the cash rate increases to 4.7% by the end of 2026 — implying one more 25 bp hike at some point between July and December.


Interest Rate Forecast Australia — Where to From 4.35%?

The big-four banks publish economic forecasts every quarter and update them after each RBA decision. Heading into the 5 May meeting, the interest rate forecast Australia consensus had already shifted hawkish — and the 5 May hike has cemented that. The next round of big-four updates is expected after the May SMP and the late-May/early-June CPI data; we'll refresh this section as those updates land. Here is where each major bank's economics team sat heading into the May meeting and immediately after:

  • Commonwealth Bank (CBA): expected the May hike and now sees the cash rate holding at 4.35% for the remainder of 2026, with the first cut not returning until Q1 2027. CBA's outlook is broadly in line with the RBA's own May SMP assumptions but more dovish on the year-end peak (CBA still 4.35%, RBA outlook 4.7%).
  • Westpac: the most hawkish of the big four. Westpac's chief economist forecast the May hike to 4.35% followed by two further 25 bp increases in July and September, taking the cash rate to a cycle peak of 4.85% — 50 bp above the November 2023 peak. Westpac sees cuts returning in the second half of 2027.
  • ANZ: forecast the May hike and base case has the cash rate holding at 4.35% for the rest of 2026, with modest cuts (25–50 bp in total) beginning in Q1 2027. ANZ flags the RBA's 4.7% outlook as a meaningful upside risk to its own call.
  • NAB: in line with ANZ — May hike to 4.35% then extended pause. NAB is slightly more dovish on the recovery, with cuts potentially starting as early as November 2026 if inflation surprises to the downside.

Across the four banks, the median 2026 peak forecast is now 4.35% — the rate we're already at — with Westpac as the hawkish outlier at 4.85% and the RBA's own outlook implying 4.7%. No major bank currently forecasts further cuts in 2026.

Independent forecasters (AMP, Deloitte Access Economics, Judo Bank) sit mostly between CBA and Westpac — most see the cash rate either holding here or ticking to 4.60% by mid-year before any easing materialises in 2027. The risk both ways remains live: a stronger-than-expected June quarter CPI print would lock in a further hike, while a sharp rise in unemployment could bring cuts forward.

Because forecasts change with every piece of economic data, treat any 2026 cash rate number as a guide, not a promise.

What to Watch Before the Next RBA Meeting

If you want to form your own view on where rates go next, there are four key data releases the RBA watches closely — and that move market pricing the most:

  • Quarterly CPI (Consumer Price Index): released by the ABS on the last Wednesday of the month following each quarter. This is the single biggest input to RBA decisions. The March 2026 quarter CPI release on 29 April 2026 is the most important number before the 5 May meeting — a headline print above 3.5% year-on-year would virtually lock in another hike, while a surprise drop toward 3.0% would put a pause back in play.
  • Monthly CPI Indicator: released mid-month, this is a lighter, partial-coverage read but useful for spotting turning points. The mid-April 2026 monthly indicator is what market pricing is reacting to right now.
  • Labour Force Survey: monthly, from the ABS. Unemployment is the other half of the RBA's dual mandate. If unemployment rises above 4.5% while inflation is still sticky, the RBA will pause rather than keep hiking. A labour market that stays tight at 3.8%–4.2% while wages grow above 4% gives the RBA cover to keep tightening.
  • Wage Price Index: released quarterly. Sustained wages growth above 4% keeps upward pressure on services inflation, which is exactly what the RBA is trying to break in 2026. A wages print at or below 3.5% would materially weaken the case for further hikes.

In practice, most buyers don't need to track these in real time — but if you're deciding between fixing and going variable in the week before an RBA meeting, knowing what data has come out in the previous 30 days gives you a much better read on the probabilities than the bank headlines.

The ASX RBA Rate Tracker consolidates all of this into a single number: the probability of a move at the next meeting, updated daily from interbank futures pricing. It's not perfect (markets are wrong all the time), but it's a clean starting point for understanding where informed money is currently positioned.


How Interest Rates Affect Your Mortgage Repayments

The mechanics of the RBA cash rate and your home loan interest rates are straightforward: when the RBA moves the cash rate, Australian lenders almost always pass the move through to variable-rate mortgages within a few days. Fixed-rate loans don't change during the fixed period, but new fixed-rate deals reprice immediately.

For a standard principal-and-interest variable-rate home loan over 30 years, the rule of thumb is that every 0.25% rate move changes monthly repayments by about $15 per $100,000 of loan. The table below shows how that plays out across common rate moves on a $500,000 home loan:

Rate changeMonthly repayment impact on $500,000 loan
+0.25%~$75 more per month
+0.50%~$148 more per month
+1.00%~$290 more per month
-0.25%~$75 less per month
-0.50%~$148 less per month
-1.00%~$290 less per month

The 5 May 2026 hike to 4.35% has already added around $75 per month to a typical $500,000 variable-rate borrower's repayments — on top of the $150-ish monthly increase already absorbed from the February and March hikes. That puts the same borrower roughly $225 per month higher than the August 2025 low. If Westpac's hawkish scenario plays out and the cash rate climbs to 4.85% by Q3 2026, the same borrower would be paying an additional $300 per month versus the August 2025 low — a $3,600-a-year hit.

On larger loans the impact compounds proportionally. An $800,000 loan at 5.0% with a 1% rate rise adds around $465 to monthly repayments. A $1 million loan adds close to $580 per month. This is why borrowers with smaller deposits and larger loans feel rate cycles much more sharply than cash buyers — your borrowing capacity and your monthly budget both move with the cash rate.

Run your own numbers through the NestPath mortgage repayment calculator to see exactly what a 25, 50 or 100 basis-point move would do to your monthly, fortnightly and weekly repayments — then check how much flexibility you have in your household budget.


What First Home Buyers Should Do Now

The honest answer is: don't build your home-buying plan around a rate forecast. Forecasts are wrong often enough that betting a multi-hundred-thousand-dollar decision on one is risky. A better framework is to focus on what you can control.

1. Get pre-approved now — don't wait for the "perfect" rate. Pre-approval is free, it's valid for 3–6 months, and it tells you the real number you can borrow at today's rates. The "I'll wait for rates to drop" strategy has burned Australian buyers repeatedly — most recently those who waited through the early 2025 cuts expecting more, only to see rates rise again in early 2026. Property prices also don't sit still while you wait. The right time to have pre-approval ready is before you start actively hunting, not after.

2. Stress-test your budget at a rate 1% higher than today. APRA requires your lender to do this as part of serviceability assessment (the 3% buffer). Do it for yourself too, with your real-world spending rather than the HEM benchmark. If your variable-rate repayments would be painful at a cash rate of 4.85%, you're probably borrowing too close to your theoretical maximum. Borrow the amount you can comfortably afford at a rate 100–150 bp above today's — that gives you genuine protection through the rest of any tightening cycle.

3. Consider fixing part of your loan if you want certainty. With major-bank economists forecasting further hikes before any cuts return, fixed rates offered today may represent near-peak pricing. A split loan — part fixed, part variable — gives you certainty on half your repayments while leaving the other half free to benefit from eventual cuts and to accept extra repayments. The right split depends on your risk tolerance, not on any single forecast. Read the full fixed vs variable home loan guide for a framework to decide.

4. Use a broker to compare rates across 30+ lenders. Headline bank rates are often 30–50 basis points higher than the best rates available in the market for the same loan. Brokers see the full pricing grid across all the majors and dozens of second-tier lenders (Bank of Queensland, ME Bank, Suncorp, Macquarie, ING, AMP, Bankwest, Heritage, Bendigo). On a $500,000 loan, a 0.4% rate difference is $2,000 a year — roughly $60,000 over the life of the loan. Getting a broker to shop your loan properly is one of the highest-ROI moves a first home buyer can make. NestPath connects you with a vetted first home buyer broker at no cost.

5. Don't over-optimise for the rate at the expense of everything else. Loan features matter too — offset accounts, redraw flexibility, extra-repayment limits, fee structure, refinance penalties. A loan with a 0.1% higher rate but a proper 100% offset account can save you more over time than a cheap loan with no offset, depending on how much cash you typically keep in your linked accounts. Rate is the headline; the full loan structure is the real story.

6. Already a homeowner? Diarise a refinance check every 24 months. Rates move constantly and the best deal on the market today is almost never the one you signed up for two years ago. A 0.5% rate cut on a $500,000 loan is roughly $200 a month — see our refinancing home loan guide for the full cost/saving framework and step-by-step process.


Should You Fix or Go Variable in 2026?

The fix-vs-variable question is one of the most common first home buyer questions, and the answer depends heavily on where we are in the cash rate cycle. With the cash rate at 4.35% as of 5 May 2026 and the RBA's own outlook pointing to 4.7% by year-end, here's the honest framing:

Case for fixing: if your budget is tight and another 25–50 basis points of rate rises would genuinely stress your repayments, locking in today's rate removes that risk. Fixed rates on offer today (typically 5.5%–6.2% for 1–3 year terms) already price in some expected further tightening, but if Westpac's 4.85% scenario plays out, variable rates keep rising while your fixed rate stays put. For pure cash-flow protection, fixing part or all of your loan makes sense.

Case for variable: if your household income has comfortable buffer above minimum repayments even at a hypothetical 6.5%+ mortgage rate, and if you're likely to make extra repayments or park cash in an offset account, variable wins. Variable rates allow unlimited extra repayments (fixed rates typically cap at $10,000–$30,000 per year with break costs beyond that) and almost always come with a 100% offset account (most fixed rates do not). When the rate cycle eventually turns, variable rates drop immediately — fixed-rate holders wait until their term ends.

The split: most Australian first home buyers who use a broker end up with some version of a split loan — a minority portion fixed for 1–3 years for budget certainty, the majority variable for flexibility. The right split isn't a formula; it's a function of your income stability, your cash reserves, and how much psychological comfort you need around your monthly payment. Read the full fixed vs variable home loan guide or talk to a broker to model the split against your own numbers.

One thing to avoid in any rate environment: locking a big fixed-rate chunk at a cycle peak. If the May 2026 meeting confirms that 4.35% is the peak and the next move is eventually down, fixing at today's rates is worse than waiting three months for rates to start easing. No one can time the cycle perfectly, but you don't have to — split loans and shorter fixed terms (1–2 years) let you hedge without making a high-stakes bet.


The Bottom Line

Rates rose faster than anyone expected in 2022–23, fell faster than expected through 2025, and have just resumed rising in 2026. The next RBA move is expected to be up, but the speed and final height of any further tightening remains genuinely uncertain. The best protection isn't forecasting the cycle — it's buying well inside your stress-tested budget, using a broker to secure the best rate structure, and revisiting your loan every 12–24 months to make sure you're still on a competitive deal.

If you're actively looking, start with pre-approval. The free NestPath borrowing power calculator will give you a realistic number to work with, and a vetted first home buyer broker can turn that into formal pre-approval within a week — at no cost to you.


Frequently Asked Questions

What is the current interest rate in Australia?

The RBA cash rate target is currently 4.35%, effective from 5 May 2026 after a 25 basis point increase at the May Monetary Policy Board meeting — the third consecutive hike of the 2026 tightening cycle and a return to the late-2023 peak. Standard variable home loan rates at the big four banks now sit roughly in the 5.95%–6.55% range at this cash rate level, with best-in-market discounted variable rates available through brokers from around 5.55%–5.95% for borrowers with a 20%+ deposit.

Will interest rates go down in 2026?

Probably not. As of April 2026, none of the big four Australian banks forecasts cash-rate cuts in 2026. CBA, ANZ and NAB expect one more 25 bp rise at the May meeting to 4.35%, then a hold for the rest of the year. Westpac is more hawkish, forecasting additional increases that could push the cash rate as high as 4.85% by August. The earliest any major bank sees cuts returning is late 2026 (NAB) or early 2027 (CBA, ANZ). When interest rates eventually go down again, expect a slow, staggered easing of 25 bp at a time rather than rapid cuts — the RBA has signalled it will keep rates restrictive until inflation is back inside the 2–3% band on a sustained basis.

How do interest rate changes affect my mortgage?

On a standard 30-year variable-rate principal-and-interest home loan, every 0.25% rate move changes monthly repayments by about $15 per $100,000 of loan. On a $500,000 loan that is roughly $75 per month per 0.25% move — so a 1% rise adds around $290 to monthly repayments, and a 1% cut cuts them by the same. Fixed-rate loans do not change during the fixed period, so the impact on fixed-rate borrowers is delayed until the fixed term expires. Use the mortgage repayment calculator to model the impact on your exact loan size and rate.

Should first home buyers fix or go variable in 2026?

It depends on your risk tolerance and budget headroom. With the RBA currently in a tightening cycle and no cuts forecast in 2026, fixing part of your loan for 1–3 years provides budget certainty if further hikes would genuinely stress your repayments. Variable rates give you unlimited extra repayments, full-offset-account access and immediate benefit when rates eventually drop. Most first home buyers who work with a broker end up with a split loan — typically 20–50% fixed and the rest variable — to hedge both ways. Avoid fixing a large portion right at the cycle peak; shorter fixed terms (1–2 years) and split loans give you optionality without betting everything on one forecast.
