Big-4 Bank Variable Rate Showdown 2026: CBA vs ANZ vs WBC vs NAB

Introduction

The Australian mortgage market turns on the pricing decisions of the four major banks: Commonwealth Bank of Australia (CBA), Australia and New Zealand Banking Group (ANZ), Westpac Banking Corporation (WBC), and National Australia Bank (NAB). Together they hold approximately 72 per cent of all owner-occupied and investment housing loans by value, according to the Australian Prudential Regulation Authority’s (APRA) quarterly authorised deposit-taking institution statistics for the September 2024 quarter (APRA, 2024). For English-speaking borrowers comparing headline offers, the noise of package discounts, negotiating headroom, and ever-moving variable rates makes choosing a lender harder than scanning a comparison rate sticker. This article dissects the variable-rate offering of each big-four bank as it stands in 2026, referencing the cash rate trajectory, funding cost differences, LVR tiers and non-resident restrictions. Every rate cited is drawn from the respective bank’s published schedule or a Commonwealth authority source.

The 2026 Macro Backdrop: RBA Cash Rate and Funding Costs

Variable home loan rates flow, in part, from the Reserve Bank of Australia’s (RBA) cash rate target. In February 2026 the RBA Board left the cash rate unchanged at 3.85 per cent, having reduced the target by a cumulative 50 basis points during the second half of 2025 (RBA, Statement on Monetary Policy, February 2026). Each big-four bank passes through cash rate changes unevenly. CBA and Westpac, with large retail deposit bases, tend to reprice standard variable rates (SVRs) by 20‑25 basis points for each 25‑basis‑point RBA cut—slightly less than the full move when funding costs from wholesale markets remain elevated. ANZ and NAB, more exposed to short-term wholesale funding, tracked the cash rate move almost perfectly in the 2025 easing cycle, according to the ACCC’s Home Loan Price Inquiry interim report (ACCC, September 2025). The result is that headline SVRs across the majors sat in a narrow band of 5.74–6.09 per cent per annum for owner-occupiers making principal-and-interest repayments with a loan-to-value ratio (LVR) at or below 80 per cent in March 2026.

Headline Variable Rates: March 2026 Comparison

The table below reproduces the banks’ own published owner-occupier principal-and-interest standard variable rate and the associated comparison rate as at 4 March 2026. The comparison rate is calculated on a $150,000 loan over 25 years and includes certain fees and charges; it is a statutory tool under the National Consumer Credit Protection Act 2009 and should be read alongside the headline rate.

Source: CBA, Westpac, NAB, ANZ home loan rate schedules, 4 March 2026. All rates are for owner-occupiers, principal and interest, LVR ≤80% and a package-linked loan with an annual fee of $395 (CBA/ANZ) or $395-$420 (Westpac/NAB).

The headline gap of 35 basis points between ANZ (the cheapest on the SVR measure) and CBA (the most expensive) may understate or overstate real borrowing costs because the banks structure discounts and package benefits differently.

Discounts and Life-of-Loan Pricing: What Borrowers Actually Pay

No borrower with a sound credit history and stable income pays the headline SVR. Each major bank offers a “basic” no-frills product with a discount in the range of 0.90–1.15 percentage points and a packaged offering that layers in an offset account and credit-card waiver for 0.70–0.95 percentage points below SVR. When those discounts are applied, the effective packaged variable rates for an LVR ≤70% owner-occupier loan of $500,000 sit closer to:

• CBA Wealth Package: 5.14%
• Westpac Premier Advantage: 5.09%
• NAB Choice Package: 4.89%
• ANZ Breakfree: 4.83%

ANZ’s three-point margin advantage persists after discounts. Still, CBA and Westpac have reduced the effective rate gap during the last two years by offering larger relationship discounts—up to 0.15 percentage points for customers who hold at least three products (transaction account, credit card and general insurance) with the group. NAB has relied on the shortest conditional approval turnaround among the majors (median 4 business days in the September 2025 quarter, as reported to the ACCC Home Loan Inquiry) to attract refinancers who prioritise speed over the last few basis points. The takeaway for English-speaking borrowers is that the screen rate is a starting point for negotiation; a broker can often unlock a further 10‑15 basis points off the advertised discounted rate.

Offset, Redraw and Package Fee Structures

All four majors offer full transactional offset accounts on their packaged variable loans. An offset facility applies the credit balance in the offset account to reduce the interest calculated on the home loan principal without reducing the loan balance. This feature is attractive for borrowers with substantial cash buffers or those who want flexibility without triggering a redraw event (which can have future tax consequences if the property later becomes an investment).

Package fees range from $395 to $420 per year and typically include a fee-free credit card (saving $30‑$300 annually depending on the card), a fee waiver on the offset account (otherwise $10–$15 per month) and a small discount on home and contents insurance. Table 2 summarises the key cost points.

Westpac’s package fee is the highest, but the bank offers a slightly lower variable rate to offset the difference for loans above $250,000. The economic decision on which package is optimal hinges on the interaction between the interest rate saving and the packaged perks versus a basic loan with a cheaper rate but a $10 monthly offset fee.

LVR Tiers, LMI and Regulatory Guardrails

APRA’s prudential standard APS 220 requires lenders to apply a minimum 3.0-percentage-point serviceability buffer above the product rate when assessing new variable-rate applications, unchanged since the buffer was increased from 2.5 percentage points in October 2021 (APRA, October 2021). For an ANZ packaged customer paying 4.83 per cent, the assessment floor is 7.83 per cent. Across all four institutions, borrowers with an LVR above 80 per cent incur lenders’ mortgage insurance (LMI) and may face a rate loading of 0.10–0.25 percentage points depending on the precise LVR band. In 2026 the majors use the following LVR breakpoints for their core variable products:

• ≤60%: best discounted rates, no LMI
• 60.01–70%: 1–2 bp loading but still top-tier discounts
• 70.01–80%: highest discount band without LMI
• 80.01–90%: small rate loading (0.05–0.15%) plus LMI
• 90.01–95%: higher rate loading (up to 0.25%), LMI required, and a maximum loan term of 30 years

ANZ and NAB accommodate 95 per cent LVR (including capitalised LMI) for owner-occupier purchasers, whereas CBA and Westpac cap standard variable loans at 95 per cent for first-home buyers only and tighten to 90 per cent for subsequent purchasers. APRA’s quarterly data show the share of new loans originated above 90 per cent LVR stabilised at 7.2 per cent in the December 2025 quarter, well below the 10 per cent benchmark APRA uses as a trigger for macroprudential intervention. This means the current LVR limits are likely to remain steady through 2026.

The Non-Resident and Foreign-Income Dimension

English-speaking borrowers earning income outside Australia or classified as foreign persons under the Foreign Acquisitions and Takeovers Act 1975 face a different set of rules. The Foreign Investment Review Board (FIRB) requires foreign buyers to obtain approval before purchasing residential property, and most new lending to non-residents attracts a 0.50–1.00 percentage point surcharge above the standard variable rate. In addition, the major banks’ maximum LVR for a non-resident borrower is limited to 70‑80 per cent, and all four require the loan to be serviced in Australian dollars using Australian-sourced income, unless the borrower qualifies under a specific expatriate policy. For an ANZ expatriate applicant earning in Singapore dollars or US dollars, the bank applies a 20 per cent income haircut and limits the LVR to 70 per cent. NAB’s expatriate policy permits loans in select foreign currencies but adds a risk margin of 0.40 percentage points. CBA and Westpac generally only accept foreign-income applications from permanent residents or citizens with a clear intention to return to Australia within three years. For cross-border borrowers, the cost of a variable home loan can be 6.20–7.00 per cent per annum after surcharges, making a mortgage broker with cross-border experience indispensable.

When Variable Beats Fixed: 2026 Rate Outlook

With the RBA signalling a cautious easing cycle—the February 2026 Statement on Monetary Policy projected trimmed mean inflation returning to the 2–3 per cent band by mid-2026—most market economists forecast one further 25-basis-point cut in the cash rate later in the year, followed by a pause. In this environment a variable rate offers the prospect of lower repayments without the cost of breaking a fixed contract. The three-year fixed rates on offer from the big four in March 2026 sit between 5.35 and 5.55 per cent, approximately 30‑70 basis points above the best discounted packaged variable rates. The break‑even analysis turns on the borrower’s view of the cash rate path: if the cash rate is reduced twice more by December 2026, the effective variable rate would cross below today’s three-year fixed rate. Conversely, if funding pressures from international capital markets re-emerge and push up swap rates, the bank could reprice variable loans higher even if the cash rate does not move. Between 2015 and 2024, SVRs moved independently of the cash rate three times (out of 44 OCR decisions), each driven by increases in short‑term wholesale funding costs. Borrowers should be aware that variable rates are exactly that—variable.

Conclusion: No Single Winner, Just Trade-Offs

The big-four variable-rate contest in 2026 lines up as follows: ANZ continues to produce the lowest headline and packaged variable rate, aided by a larger proportion of low-cost deposit funding relative to wholesale liabilities. NAB offers the second‑lowest rate and the fastest approval speeds. Westpac sits in the middle on price but provides the most generous packaged credit-card inclusion, while CBA charges a small premium but couples it with leading digital banking infrastructure and the largest branch network, which may hold value for borrowers seeking in‑person support. For a $750,000 owner-occupier loan with 70 per cent LVR, the difference between the cheapest and most expensive packaged variable product is approximately $1,900 per year in interest—meaningful but not dispositive if the cheaper lender processes the application 10 days more slowly and the borrower misses a settlement deadline. As with any financial commitment, rates are only one part of the due diligence equation.
