Commonwealth Bank of Australia has raised its special offer 12-month term deposit rate to 5.20% per annum, adding fresh momentum to Australia’s intensifying competition for household savings. The move comes just ahead of the Reserve Bank of Australia’s next interest rate decision, where many economists expect another rate increase.
The latest adjustment reflects how major banks are trying to attract deposits in a higher-rate environment. With ANZ still offering the top 12-month rate among the big four at 5.25%, the battle for savers is becoming increasingly aggressive.
Key Overview
CommBank’s new special offer rate applies from May 1 for deposits between A$5,000 and A$5 million, with interest paid annually. The new 5.20% rate is a sharp rise from the 4.25% offer available in January. The change comes as markets widely expect the RBA to raise the cash rate from 4.10% to 4.35%. Meanwhile, ANZ leads the major banks at 5.25%, while NAB and Westpac sit around 5.10% for comparable one-year products.

CommBank Raises Deposit Rates Again
Commonwealth Bank of Australia has increased its special offer 12-month term deposit rate to 5.20% per annum, continuing a pattern of regular increases seen throughout 2026. The move underlines how major Australian banks are competing more aggressively for customer deposits as interest rate expectations remain elevated.
The new offer takes effect from May 1 and is available for balances ranging from A$5,000 to A$5 million. Interest is paid annually under the latest terms.
For savers, the increase provides a more attractive fixed return at a time when many households are rethinking where to place cash balances. For banks, it reflects a broader need to secure stable funding in a competitive environment.
A Sharp Increase Since January
The latest 5.20% offer is significantly higher than CommBank’s 4.25% special offer available in January. That means the bank has lifted rates by nearly a full percentage point in just a few months.
Such rapid repricing highlights how quickly funding competition can change when markets expect central bank tightening or when banks want to attract more deposits.
Deposits remain one of the most important sources of funding for commercial banks. When lending demand remains strong or wholesale funding becomes more expensive, banks often turn to retail savers with higher rates.
This explains why term deposit promotions can rise even before official policy rates move again.
Why the Timing Matters
CommBank’s latest move comes just ahead of the Reserve Bank of Australia’s next monetary policy announcement. The RBA cash rate currently stands at 4.10%, but economists widely expect another increase.
According to a Reuters poll, 30 out of 33 economists expected the central bank to raise the cash rate by 25 basis points to 4.35%.
If that occurs, it would reinforce the current high-rate environment and potentially create room for further competition among banks for household savings.
Markets are closely watching because term deposit pricing often moves in anticipation of central bank decisions rather than only after them.
Competition Among the Big Four Intensifies
Although CommBank’s 5.20% rate is competitive, it does not currently top the major bank rankings for 12-month deposits. ANZ holds that position with a 5.25% annual rate for balances between A$5,000 and under A$2 million, with interest paid at maturity.
ANZ’s offer matches Macquarie Bank’s comparable 12-month rate for balances of A$1 million or less.
Meanwhile, NAB and Westpac are both around 5.10% for similar one-year products, though product conditions vary.
This means the spread between the big banks is relatively narrow, forcing savers to compare not just headline rates but also payment timing, eligibility rules, and deposit caps.
Why Banks Are Fighting for Deposits
Deposit competition usually intensifies when cash becomes more valuable. In low-rate eras, savers may accept minimal returns because alternatives are limited. In higher-rate environments, however, households become more sensitive to where they store funds.
A difference of 0.25% or 0.50% can become meaningful for larger balances. That forces banks to compete more actively if they want to retain deposits or attract new ones.
From the bank’s perspective, customer deposits are often considered a more stable funding source than some wholesale market borrowing channels. That makes term deposit campaigns strategically important.
Household Savings Are Back in Focus
For several years, many consumers paid limited attention to cash returns because rates were extremely low. That is changing.
As term deposits move above 5%, conservative savers who avoided equities or property risk may again find fixed income products appealing. Retirees, income-focused households, and risk-averse investors are especially likely to notice these rates.
Cash products are also regaining relevance because market volatility remains possible in shares, property affordability remains stretched, and some households prefer certainty.
In simple terms, cash is becoming investable again.
CommBank’s Longer-Term Offers Also Rise
CommBank did not only raise its 12-month rate. It also increased 24 to 33 month term deposit rates by 25 basis points to 5.20% for balances between A$5,000 and under A$50,000, with annual interest payments.
For larger balances between A$50,000 and A$5 million, the bank offers 5.25% annually.
This pricing suggests CommBank wants to encourage customers not just to deposit funds, but to lock them away for longer periods.
Longer maturities can help banks improve funding visibility and reduce refinancing uncertainty. For customers, they offer certainty but reduce flexibility.

Westpac and NAB Still Competing
Westpac is offering a 24-month special online-only product at 5.20%, matching part of CommBank’s longer-term pricing. Westpac reportedly accepts balances up to A$2 million with annual interest payments.
For 12-month products, Westpac offers up to 5.10% through a combination of a fixed special rate and an online bonus. NAB is also advertising 5.10% for 12-month balances up to nearly A$2 million.
This demonstrates that the market is highly active. No major bank wants to be visibly uncompetitive in a period where savers are comparing rates more carefully.
What Savers Should Consider Beyond the Headline Rate
While the top advertised percentage usually gets attention, the best term deposit is not always the one with the highest number.
Interest payment timing matters. Some products pay at maturity, while others pay annually or periodically. Early withdrawal rules also matter, as breaking a term deposit can reduce returns.
Deposit caps, minimum balances, online-only conditions, and renewal rules can also affect value.
A 5.20% product with more flexibility may suit one saver better than a 5.25% product with tighter restrictions.
What If the RBA Hikes Again?
If the Reserve Bank raises the cash rate to 4.35%, some banks may continue nudging deposit offers higher. However, the relationship is not always immediate or one-to-one.
Banks consider several factors beyond the cash rate, including funding mix, loan demand, margins, competitor pricing, and customer retention needs.
Still, higher official rates generally create upward pressure on deposit returns over time.
If Westpac’s forecast of a higher cycle peak proves correct, deposit competition could remain active for longer than many expect.
Why This Matters for the Economy
Rising deposit rates can influence broader economic behavior. Higher returns may encourage saving rather than spending, which can help cool inflationary demand.
They can also shift money away from riskier assets such as speculative investments or highly leveraged property plays.
For banks, however, higher deposit costs can squeeze margins if lending rates do not rise proportionally. That means deposit competition is positive for savers but not automatically positive for bank profitability.
What Investors Are Watching
Bank shareholders often watch deposit trends closely because funding costs are central to earnings performance.
Commonwealth Bank shares ended Friday at A$173.04, down 0.36%, while the ASX 200 rose 0.74% near 8,730. Although daily share moves are influenced by many factors, investors remain attentive to how competition for deposits may affect future margins.
If banks pay materially more for deposits without equivalent lending income growth, profitability pressure can emerge.
Final Takeaway
CommBank’s move to lift its 12-month term deposit rate to 5.20% shows that Australia’s battle for household savings is intensifying. With ANZ offering 5.25% and rivals close behind, savers are seeing some of the most attractive cash returns in years.
The timing ahead of the RBA’s rate decision suggests banks expect policy to remain restrictive and funding competition to stay strong.
For consumers, this is a rare moment when comparing cash products can meaningfully improve returns. For banks, it is a reminder that in a higher-rate world, deposits are no longer cheap or passive—they are contested assets.
