Before the 29 April CPI and 5 May RBA: the 6-day mortgage playbook for Australian borrowers (April 2026)

By Bishnu Adhikari, mortgage broker and director, Azure Home Loans — Thursday, 23 April 2026.

In six days, the Australian Bureau of Statistics will release the March quarter Consumer Price Index. Twelve days from now, the Reserve Bank's Monetary Policy Board decides whether to lift the cash rate for a third consecutive meeting — from 4.10% to 4.35% — undoing every one of the three rate cuts delivered in 2025.

That is the week. Those are the dates. And for most Australian mortgage holders, the decisions you make in the six days between those two events will matter more than anything you did in the preceding twelve months.

This article is what I am telling my own clients this week. It is not a forecast, and it is not financial advice for your specific situation. It is the factual backdrop, three scenarios priced against a real $600,000 loan, and a day-by-day checklist built from what actually moves in banks' credit pipelines when a big macro number lands.

Want a personal stress-test on your loan before 29 April? Call or text me on 0400 77 77 55 or message me on WhatsApp. I will model your repayments under all three RBA scenarios in under 20 minutes — no cost, no commitment, no sales pitch. That is what a good broker should do in a week like this.

The two dates that matter

Where the cash rate actually is right now

The RBA has now hiked twice in 2026:

• 4 February 2026: +25 bp, taking the cash rate from 3.60% to 3.85%
• 17 March 2026: +25 bp, taking it from 3.85% to 4.10%

The Board vote at the March meeting was 5–4 — the narrowest majority of this cycle. Four Board members judged that the existing tightening was already doing enough work and voted to hold.

That narrow vote is the reason 5 May is genuinely uncertain despite the market pricing. A 60% probability of a hike is also a 40% probability of a hold, and four Board members have already shown their hand.

What the major banks are forecasting for 5 May

Current as of this week — big-four economist forecasts shift regularly; these are the published house views going into the May meeting.

AMP's Shane Oliver: "Our base case is they will hike, but it's not a certainty. Roughly a 60% chance of a hike, a 40% chance they will hold." UBS describes the RBA as a "hawkish outlier" among global central banks.

Why 29 April CPI matters more than any CPI this year

The ABS transitioned to a complete monthly CPI series from November 2025. The 29 April release carries the March monthly reading plus the full March quarter detail (tables 17–18 of the ABS publication), which is the cut RBA forecasting models consume.

Right now, the inflation picture looks like this (ABS CPI, February 2026 release, published 25 March):

• Headline CPI: 3.7% annual (down marginally from 3.8% in January)
• Trimmed mean (the RBA's preferred measure): 3.3% annual — unchanged for three months
• Housing: +7.2% annual — still the largest contributor to inflation
• Food and non-alcoholic beverages: +3.1% annual

What the Board is watching on 29 April is whether the trimmed mean has moved. The RBA's target band is 2–3%. Trimmed mean at 3.3% for three consecutive months is just above that band and stalling. If the March reading shows even modest progress toward 3%, the case for holding strengthens. If trimmed mean prints at 3.4% or higher, the case for hiking to 4.35% becomes close to overwhelming.

The second thing the Board is watching is the pass-through of energy prices from the Middle East conflict. The February and March 2026 hikes were both partly justified as pre-emptive moves against imported inflation from a supply shock. The March quarter CPI will be the first full picture of how much of that has actually landed in Australian retail prices.

Three scenarios, priced against a real $600,000 loan

I am going to use a standard example: a $600,000 owner-occupier principal-and-interest loan, 30-year term, currently on a variable rate of 6.10% — which is roughly where the average owner-occupier variable sat after the March hike flowed through the big four. Current monthly repayment at 6.10%: $3,637.

Scenario 1 — "Hot" CPI (Board hikes to 4.35%)

Trimmed mean prints at 3.4% or higher, or quarterly CPI runs hot on energy and housing. Probability today: I would put it around 45–50%.

• Cash rate rises to 4.35% on 5 May
• Major banks pass through the 25 bp in full within 7–14 days (they did it inside five days in February and March)
• Your variable rate rises to ~6.35%
• New monthly repayment: $3,731 — +$94/month, +$1,128 for the year

If Westpac's hawkish track is right and two further hikes follow in June and August to 4.85%, the same loan is paying $3,923/month by September 2026 — +$286/month versus today, $3,432 for the year.

Scenario 2 — "In line" CPI (Board split; small probability skew toward hike)

Trimmed mean unchanged at 3.3%, headline CPI around 3.6–3.8%. Probability: 30–35%.

• 5 May becomes a genuine coin flip
• Futures market pricing collapses toward 50/50 in the two days after CPI
• If the Board hikes: same as Scenario 1
• If the Board holds: cash rate stays at 4.10%, your variable stays at 6.10%, but the market starts pricing a June hike instead — fixed rates keep drifting higher

Scenario 3 — "Soft" CPI (Board holds)

Trimmed mean prints at 3.1–3.2%, headline CPI below 3.5%, with quarterly momentum clearly easing. Probability today: 15–25%.

• Cash rate holds at 4.10%
• Some lenders begin trimming margins on new variable rates to compete for refinance flow
• Fixed rates stabilise; a few 1-year fixed deals may drift back toward the 5.5–5.8% range
• Your variable repayment stays at $3,637
• The RBA's next decision (16 June) becomes the next focal point

A word of honesty. None of these three scenarios involves rates falling meaningfully this year. Not one major bank's economics team currently forecasts a cut in 2026. The tightening cycle has re-started, the only debate is how high it goes.

The 6-day playbook — what I am actually telling clients this week

This is the day-by-day I am running for my own book. Adapt it to your file.

Thursday 23 April – Friday 24 April (today and tomorrow)

• Get a current rate read. If you have not had your rate checked in the last six months, get it done. Some lenders have quietly moved your existing variable up by more than the 50 bp of cash-rate hikes this year. I will do this over the phone in 10 minutes.
• Confirm your break fee if you are on a fixed rate. Fixed break costs move with swap rates, and swap rates have been volatile since the March hike. Ask for a current break quote in writing — it is usually valid for 14 days.
• Gather two payslips and your most recent home loan statement. If the CPI is hot and we decide to move, having these ready saves 3–5 business days in the application window.

Monday 27 April – Tuesday 28 April

• Decide your trigger. Do not leave this until Wednesday morning. Commit to a rule now: "If trimmed mean prints at X or higher, I submit an application on Thursday. If it prints at Y or lower, I stay put." Trigger-based decisions beat emotion-based decisions every time on macro weeks.
• Shortlist two options: your best refinance target and your best retention ask at your existing bank. ANZ is currently offering existing customers who have lodged discharge paperwork a $2,000 retention payment plus 15–20 bp discounts off competitors' rates (AFR, 16 April 2026). The other majors are starting to follow quietly.

Wednesday 29 April, 11:30am AEST — CPI release

• Do not react in the first 30 minutes. Headlines move violently on the top-line number. Wait for the RBA forecasters (CBA, Westpac, AMP, UBS) to publish their trimmed-mean and quarterly breakdowns — usually by 1pm.
• Re-pull futures market pricing at 2pm. If the May hike probability moves from 60% into the 80%+ range, I am submitting refinance applications and fixed-rate lock requests that afternoon. If it drops below 40%, I am holding.

Thursday 30 April – Monday 4 May

• Lodge by end-of-day Friday 1 May if you are moving. Most lenders will not price-lock a rate more than 90 days out, and applications lodged after Monday 4 May will settle under post-RBA pricing regardless.
• If you are going fixed, request rate-lock in writing. Lock fees are currently running 0.10–0.15% of the loan amount at most majors. On a $600,000 loan that is $600–$900 — cheap insurance if the Board hikes.

Tuesday 5 May, 2:30pm AEST — RBA decision

• Expect your lender to email within 48 hours if there is a move. Every big-four bank passed the February and March hikes through within five business days. Diarise a rate check for 15 May.

I run this playbook for every client, every RBA week. If you want me to run it for you this time — including the rate check, the trigger rule, and the lender shortlist — call 0400 77 77 55 or message me on WhatsApp. The call takes 15 minutes. There is no cost.

The refinance cashback war — and why it is not a reason to refinance

The cashback market has got noisy in the last fortnight. Current published offers as of this week:

Source: Canstar — April 2026 refinance cashback comparison.

Here is the honest broker read on cashbacks. A $3,000 cashback on a $600,000 loan is the equivalent of about 0.50% off your rate for a single year. If the lender offering that cashback is sitting 0.30% above the sharpest non-cashback rate in the market, you are paying them back within year two, and losing money by year three. Check the total cost over a 3–5 year hold, not the sticker.

The other quiet risk: cashbacks are often paired with slower service SLAs, less flexible offsets, or product fine print (e.g. restrictions on splits, redraw limits, or LVR tolerances on top-ups down the track).

A cashback is worth exactly what a cashback is worth — no more. It is never, by itself, a reason to refinance.

Fixed vs variable — the April 2026 snapshot

The market has pulled apart sharply since the March hike.

• Lowest variable rate in the market: 5.44% (Laboratories Credit Union / LCU), owner-occupier, 80% LVR — per Canstar's April 2026 comparison
• Average owner-occupier variable (post-March hike pass-through): 6.42% for principal and interest
• Lowest fixed rate in the market: 5.49% (Northern Inland Credit Union, 1-year fixed, owner-occupier)
• Only 89 home loans on Canstar's database priced below 5.75% — down from 101 the previous week

Fixed-rate pricing has broken 6% across the major banks. 490 individual fixed rates were lifted by an average of 0.32% in the fortnight to mid-April. If you are considering fixing, the universe of sub-5.5% offers is collapsing.

My personal read this week:

• If you are more than 12 months from the end of a current fixed rate, do not move on the fix. Run the numbers after 29 April.
• If you are on variable and refinance-ready, a partial fix — say 50–60% of the loan for 1 or 2 years — is a reasonable hedge against the Westpac 4.85% scenario while keeping offset flexibility on the variable portion.
• If you are on a variable above 6.40% without offset or redraw features, there is almost certainly a sharper deal waiting for you regardless of what happens on 5 May.

Frequently asked questions

Is the RBA definitely hiking on 5 May?

No. Markets are pricing 60–62% probability, and the March vote was 5–4. CBA, NAB, Westpac and ANZ all forecast a hike to 4.35%. ANZ's base case is a hike then an extended pause. The single biggest input between now and 5 May is the March quarter CPI on 29 April.

Should I refinance before 29 April or wait?

It depends on two things: your current rate, and whether your file is ready. If your variable is above 6.40% and your documents are current, locking in application now gives you options in either direction. If you are under 6.00% and your file needs work, use the next six days to prepare — then decide after 29 April.

Should I fix my rate now?

The lowest fixed rates in the market (5.49% 1-year from Northern Inland Credit Union) are below some variable rates. But the majors are now above 6% on their sharpest fixed products. If the Westpac scenario plays out and the cash rate reaches 4.85% by August, sub-5.5% fixed rates will look brilliant in hindsight. If CPI surprises soft and the Board holds on 5 May, fixed pricing may drift back. A partial fix is how I split that uncertainty for most clients.

My lender just hiked my rate — can I push back?

Yes. ANZ is on record paying $2,000 retention payments plus 15–20 bp discounts to customers who lodge discharge paperwork. The other majors are matching quietly. The leverage only works if you have a written offer from another lender in hand — a refinance pre-approval is the specific document that moves a retention team.

What if inflation drops sharply on 29 April?

A print with trimmed mean at 3.1% or below and clear quarterly momentum easing would likely take the May hike off the table. Expect fixed-rate pricing to stabilise, some variable retention offers to soften, and the market focus to shift to the 16 June RBA decision. This is still not a cut scenario — no major bank currently forecasts a 2026 cut.

Does the 5 May decision affect the First Home Guarantee or Help to Buy?

Not directly. The First Home Guarantee now has unlimited places, no income caps, and higher property price caps from 1 October 2025. The Help to Buy shared-equity scheme (CBA and Bank Australia at launch) has already approved over 2,356 places and settled 278 households since its 5 December 2025 launch. Cash-rate moves affect the interest rate you pay on the loan portion — not your eligibility for either scheme.

I bought in late 2023 at the last peak — am I about to see that rate again?

If the Board hikes to 4.35% on 5 May, yes — that matches the November 2023 peak. If Westpac's 4.85% track plays out by August, you will be above your 2023 rate. Stress-testing your budget at 4.85% — not just 4.35% — is the prudent exercise this week.

How quickly can you actually run the stress-test?

On most files, 15–20 minutes on the phone. I need your current loan balance, rate, lender, a recent payslip and a 30-second chat about your goals. I will send back a one-page summary modelling all three scenarios against your actual loan. At no cost. That is the job.

The bottom line

The next twelve days are not normal. The 29 April CPI is the most important mortgage data release of 2026 so far, and the 5 May RBA decision has a real chance of pushing the cash rate back to its November 2023 peak — or staying put, depending on one number.

If you do nothing else in the next week, do two things:

1. Get a current rate check from an independent broker — someone who sees rates across 30+ lenders, not just one bank's book
2. Write down your trigger rule before Wednesday — the CPI print is not a decision, it is a signal. Decide in advance what you will do under each scenario

Get both of those done and you will walk into 5 May with a plan. Walk in without either and you will be reacting to a market that has already moved past you.
