Will Australia's Surcharge Ban Actually Cut Inflation? The 0.1% Question Every Merchant Should Understand
Australia’s card surcharge ban will begin on 1 October 2026, removing surcharges on designated eftpos, Mastercard and Visa debit, prepaid and credit card transactions.
The reform has been welcomed as a cost-of-living measure. Treasurer Jim Chalmers has said removing surcharges will give Australians greater certainty at the checkout. But whether it will reduce inflation is a more complicated question.
The Reserve Bank of Australia (RBA) estimates that removing surcharges could have a negligible, one-off impact of approximately +0.1% on measured CPI. That may sound inflationary, but it does not mean consumers will suddenly pay 0.1% more overall.
The figure is primarily an accounting effect: a cost consumers already pay through a surcharge may move into the advertised price of goods and services, which is captured differently in the Consumer Price Index (CPI).
The central message for merchants is clear: the surcharge ban is a price-transparency reform, not a major disinflationary event. It moves payment costs from the checkout line into the price tag, while lower interchange caps should reduce some of the underlying cost burden.
THE KEY TAKEAWAY
The surcharge ban will make prices easier to understand, but it will not automatically make the economy cheaper.
Around 16% of Australian merchants currently surcharge designated card payments. Those surcharges total approximately $1.8 billion a year, with consumers paying around $1.6 billion and businesses bearing the remaining $200 million.
From 1 October, merchants will need to choose whether to:
absorb payment costs in their margins;
incorporate them into base prices;
negotiate a lower-cost payment plan;
use discounts to encourage preferred payment methods; or
combine several of these strategies.
At the same time, lower interchange caps are expected to reduce merchants’ wholesale card costs by approximately $910 million a year.
The outcome will vary by merchant, sector, payment mix and acquiring arrangement. For consumers, the visible surcharge disappears: but the cost may not disappear entirely.
WHAT IS ACTUALLY CHANGING?
The RBA is removing its prohibition on card network “no-surcharge” rules. This allows the designated networks to impose rules preventing merchants from adding a payment surcharge.
The changes apply to:
eftpos debit and prepaid cards;
Mastercard debit, prepaid and credit cards; and
Visa debit, prepaid and credit cards.
American Express has also indicated it will remove surcharging from 1 October 2026, although it is not currently one of the RBA’s designated networks. Merchants should confirm the final requirements with their acquirer and payment service provider, particularly for Amex, UnionPay, wallets and other payment methods.
The reform applies to fees added because a customer pays by card. It does not automatically remove:
weekend surcharges;
public holiday surcharges;
booking fees; or
general service fees that apply regardless of payment method.
Interchange cap changes
Interchange is a wholesale fee paid between the card acquirer and card issuer. It forms part of the broader cost of accepting card payments.
Card transaction type | Current cap | New cap | Effective date |
Domestic debit and prepaid | 10 cents or 0.20% | 8 cents or 0.16% | 1 October 2026 |
Domestic consumer credit | 0.80% | 0.30% | 1 October 2026 |
Domestic commercial credit | 0.80% | 0.80% | 1 October 2026 |
Foreign-issued cards | Unregulated | 1.0% | 1 April 2027 |
These caps do not represent the complete merchant service fee. Acquirer margins, scheme fees, gateway costs, terminal charges and other services may remain.
WHY THE RBA SAYS IT IS ABOUT 0.1% TO INFLATION
The inflation question turns on how the CPI is constructed.
Today, a customer may see:
advertised price: $100; and
card surcharge: $1.
The customer pays $101, but the surcharge is not currently included in the CPI basket in the same way as the advertised price of the product or service.
After the ban, the merchant may instead display:
advertised price: $101; and
card surcharge: $0.
The customer may pay approximately the same amount, but the extra dollar has moved into the price that is measured by the CPI.
The RBA estimates that if existing surcharges were fully incorporated into sticker prices, the result would be an approximately 0.1% increase in the CPI level. Because the change happens once, it would create a temporary effect on the measured inflation rate rather than a permanent increase in the rate of inflation.
This distinction matters:
Inflation is the rate at which prices are rising.
The price level is the amount consumers pay at a point in time.
The surcharge ban may alter the price level and the way costs are recorded without creating a lasting inflationary trend.
Lower interchange caps provide a counterweight. If acquirers pass the savings through to merchants, the cost of accepting cards should fall. The RBA expects this to reduce the amount that merchants need to recover through higher base prices.
THE REAL ECONOMICS: WHO WINS AND WHO LOSES?
The reform creates different outcomes across consumers, merchants and financial institutions.
Consumers who previously paid surcharges
These consumers should benefit from a simpler checkout and the removal of visible card fees. They will no longer need to calculate whether paying with cash or another card is cheaper.
However, they may still contribute to payment costs through higher general prices if a merchant spreads acceptance costs across all customers.
Cash and non-surcharged buyers
A customer who previously paid cash at a surcharging business may have avoided the card fee. If the business increases its advertised prices, that customer could pay more than before.
This is the distributional issue at the heart of the debate: a cost previously paid mainly by card users may become part of the price paid by everyone.
The practical importance of this effect is limited by the decline in cash use. Cash represented approximately 69% of in-person transactions in 2007, but only around 15% in 2025.
Merchants that currently surcharge
These businesses lose a direct cost-recovery mechanism. But they also receive the opportunity to benefit from lower interchange caps and stronger incentives to review their acquiring plan.
A merchant on a high-cost or blended plan may find that renegotiating fees creates more value than simply reproducing the old surcharge in its base prices.
Merchants that do not surcharge
The majority of merchants do not currently surcharge. They may benefit from lower interchange costs without losing surcharge revenue.
Small merchants could benefit disproportionately because they are more likely to pay rates close to existing caps and have less negotiating power than large retailers.
Banks and card rewards programmes
Lower interchange revenue may pressure banks to change the economics of credit cards. Possible responses include:
higher annual fees;
higher interest rates;
reduced rewards earn rates;
tighter rewards caps; or
less generous loyalty programmes.
This means the consumer impact may extend beyond the checkout. A household could save on surcharges while receiving fewer points or paying more for a rewards card.
WHAT MERCHANTS SHOULD DO NOW
1. Model your pricing options
Calculate your current surcharge revenue, card mix, average transaction value and merchant service fees. Compare the cost of absorbing fees with the cost of a modest base-price adjustment.
2. Verify interchange pass-through
Do not assume the lower caps will automatically reduce your total merchant service fee. Ask your acquirer to explain:
how the new caps affect your plan;
when the savings will appear;
whether pricing is blended or unblended; and
what other fees remain unchanged.
3. Review least-cost routing
Least-cost routing (LCR) can help eligible merchants route dual-network debit transactions through the lower-cost network. Review whether LCR is enabled, operating correctly and available across your in-person payment estate.
4. Audit every checkout channel
Remove surcharge logic from:
terminals;
online checkouts;
payment links;
invoices;
subscriptions;
recurring billing;
APIs; and
customer communications.
The change must be consistent across an omnichannel operation.
5. Review discounts and customer messaging
Merchants can generally use discounts to encourage a preferred payment method, subject to applicable rules and provider arrangements. Any discount strategy should be easy to understand and should not recreate confusing checkout pricing.
6. Consolidate payment data
A unified payments platform can connect transactions, acquiring costs, reconciliation and business intelligence. Quantum Payments supports payment orchestration and analytics, helping merchants compare performance across channels and make pricing decisions using transaction-level data.
WHAT TO WATCH
The surcharge ban is one part of a broader shift in payment economics. Merchants should monitor:
whether acquirers pass the full interchange savings through;
changes to credit card annual fees, interest rates and rewards programmes;
how American Express and other non-designated networks apply no-surcharge rules;
whether BNPL providers and digital wallets gain share;
how foreign-issued card costs change from 1 April 2027; and
the RBA’s next review of mobile wallets, three-party networks, BNPL and e-commerce platforms.
The key risk is not a sudden inflation shock. It is a gradual redistribution of payment costs between merchants, cardholders, cash users, banks and payment providers.
CONCLUSION
Australia’s surcharge ban should be understood as a reform of price presentation and payment-system incentives, not as a conventional anti-inflation measure.
The RBA’s approximately +0.1% CPI estimate does not mean consumers will collectively pay 0.1% more. It reflects the possibility that existing surcharge costs move into prices that the CPI measures directly.
Some consumers will pay less at checkout. Some non-card users may pay more through higher base prices. Merchants will face greater pressure to control their payment costs, while banks may reprice credit card rewards and benefits.
The strategic question is therefore not whether surcharges disappear. They will. The question is whether merchants use the transition to build a more efficient, transparent and data-led payment strategy.

FAQ: AUSTRALIA’S CARD SURCHARGE BAN AND INFLATION
Will Australia’s surcharge ban reduce inflation?
Not materially. The RBA expects a negligible, one-off impact of approximately +0.1% on measured CPI if existing surcharges are incorporated into base prices. Lower interchange costs may offset some of the upward pricing pressure.
Why does the RBA estimate a +0.1% CPI impact?
Card surcharges are not currently included in the CPI in the same way as the underlying advertised price. If merchants move surcharge costs into their sticker prices, more of the cost appears in CPI-measured prices.
Will consumers pay less after 1 October 2026?
Some card users will pay less because the separate surcharge disappears. However, merchants may increase base prices, so the total saving will vary by business and payment method.
What happens to merchants that currently surcharge?
They must remove card surcharges on designated networks. They can absorb the cost, include it in general prices, negotiate lower payment fees or use permitted discounts to encourage preferred payment methods.
What are the new interchange caps?
From 1 October 2026, domestic debit and prepaid interchange is capped at 8 cents or 0.16%, domestic consumer credit at 0.30%, and domestic commercial credit remains capped at 0.80%. Foreign-issued cards receive a 1.0% cap from 1 April 2027.
Can businesses still apply weekend or service surcharges?
The RBA reform applies to fees added because a customer pays by card. Weekend, public holiday, booking and general service fees are outside the reform when they are not specifically tied to card payment.

Australia’s card surcharge ban is unlikely to be the inflation cure some headlines imply.
From 1 October 2026, surcharges on designated eftpos, Mastercard and Visa transactions will disappear.
But the RBA estimates the reform could create a negligible, one-off +0.1% impact on measured CPI if merchants move existing surcharge costs into their advertised prices.
That is an accounting effect, not proof that consumers will pay 0.1% more overall.
The bigger story is where payment costs move:
from a visible checkout surcharge;
into the merchant’s price structure;
and, potentially, into card fees and rewards programmes.
At the same time, lower interchange caps are expected to reduce merchants’ wholesale card costs by approximately $910 million a year.
The policy is best understood as a price-transparency reform. The economic test will be whether lower payment costs are genuinely passed through.

The key distinction is between inflation and the price level. Moving a surcharge into a sticker price can lift measured CPI once, without creating a continuing inflation trend.

For merchants, Australia’s surcharge ban is not simply a compliance task. It is a pricing strategy test.
From 1 October 2026, businesses will need to remove card surcharge logic from terminals, online checkouts, payment links, invoices and subscriptions.
The practical questions are:
How much card cost are you currently recovering through surcharges?
What will lower interchange caps actually save on your merchant service fee?
Is your plan blended, unblended or interchange-plus?
Is least-cost routing working across eligible debit transactions?
Should you absorb the cost, reprice, negotiate or use a permitted discount?
The RBA estimates approximately $910 million in annual wholesale card-cost relief for merchants. But interchange is only one component of the total acceptance cost.
Do not assume the saving has reached your P&L. Verify it.
The strongest response is a connected payments view across acceptance, routing, reconciliation and analytics.

First comment
A surcharge-free checkout does not remove the need to manage payment costs. It makes acquiring strategy, routing and fee transparency more important.
Visual concept
Use the merchant strategy image: neon pathways connecting online checkout, terminal, payment link and reconciliation data. Overlay: “Where will your payment costs go?”
Angle note
Make this operational and merchant-focused. Avoid repeating the morning post’s inflation framing. Emphasise fee verification, LCR, pricing scenarios and unified payment data.
