The RBA held the cash rate at 4.35% on 11 August 2026. Second consecutive hold. Cue the headlines about relief for borrowers.
Here is the problem with that framing: a hold is not relief. It locks in the damage. Three hikes in the first half of 2026 (February, March and May) took the cash rate from 3.60% to 4.35%, and every one of those 75 basis points is now sitting in your cost base for the full year.
For a typical Australian SME turning over $2 million with 15 staff, this rate cycle is quietly draining approximately $31,000 to $45,000 this year. That is more than most businesses pay for a full year of fractional CFO oversight, and three to four months of cash runway for plenty of small businesses. This article breaks down exactly where that money goes, line by line, so you can see the real cost and do something about it before it compounds further.
Published: August 2026
The RBA's Monetary Policy Board left the cash rate target unchanged at 4.35% at its 11 August 2026 meeting. That followed a hold in June and three consecutive 25 basis point increases before it: February (3.60% to 3.85%), March (3.85% to 4.10%) and May (4.10% to 4.35%).
In plain terms: the relief businesses felt during the 2025 cutting cycle is completely gone. The cash rate now sits 75 basis points above the mid-2025 trough, and the board has been explicit that it will lift rates further if inflation does not keep easing.
The August hold came after June quarter CPI, released on 30 July, printed at 3.8% headline and 3.6% trimmed mean. Softer than feared, still well above the 2 to 3 per cent target band. Governor Bullock's message after the meeting was that the board needs to see further progress before it can be confident inflation is heading back to target, and that a period of subdued growth will be required to get there.
Where to from here? CommBank expects the cash rate to stay at 4.35% for the remainder of 2026, with cuts not on the table until 2027. The market is far from settled though: Finder's August survey of 38 economists found 92% correctly picked the hold, but 44% still expect at least one more rise before the end of 2026. The next decision lands on 29 September.
For business owners, the planning assumption is simple: 4.35% or higher for at least the next 12 months. Anything better is upside.
The mortgage headlines give you a rough proxy: each 25 basis point move adds roughly $161 per month to repayments on a $1 million home loan, so the three 2026 hikes have that borrower paying close to $480 a month more than at the mid-2025 low. But business lending carries a commercial premium, and the impact extends well beyond a single loan.
Here is the full picture across four cost categories, using a typical $2 million revenue, 15-staff Australian SME as the benchmark. These are illustrative calculations. Your numbers depend on your facilities, your lender and your lease.
Most SMEs carry some form of equipment or asset finance. A $500,000 facility is common in trades, manufacturing, logistics and healthcare.
Say your variable rate on that loan sat around 5.75% at the mid-2025 trough. With the cash rate now 75 basis points higher, you are looking at roughly 6.50% or more depending on your risk profile and lender.
That 75 basis point increase adds approximately $3,750 per year in interest on a $500,000 facility. Over a five-year term, that is $18,750 you were not budgeting for when you signed.
The numbers scale linearly. A $300,000 loan costs an extra $2,250 per year. A $750,000 facility costs an extra $5,625. Whatever your equipment book looks like, multiply accordingly.
Variable overdraft rates track the cash rate closely. A $200,000 overdraft that cost around 6.00% at the mid-2025 trough now sits near 6.75% or above, adding approximately $1,500 per year in direct interest.
But that is the small part of this category, because 2026 delivered a second hit to working capital at exactly the wrong time.
Payday Super went live on 1 July 2026. Super guarantee is now paid with every pay run, calculated on qualifying earnings, and contributions must reach your employees' funds within seven business days of payday. The quarterly super float is gone.
For a 15-staff business with a $1 million annual payroll, super at 12% is $120,000 a year. Under the old quarterly system, up to $30,000 of that sat in your bank account for as long as three months before it was due. That buffer no longer exists. The cash leaves with every pay run.
The practical first-year cost is not the full $120,000. It is the cost of funding the buffer you lost. Depending on your pay cycle and existing cash reserves, expect an estimated $8,000 to $12,000 in additional overdraft usage or alternative funding costs. And you are funding that gap at post-hike rates.
Combined with the direct rate increase, this category is costing approximately $9,500 to $13,500 per year. Not sure how Payday Super lands on your specific payroll? Use our employee cost calculator to model the full cost per employee.
Most commercial leases in Australia include CPI-linked annual reviews or fixed percentage escalation clauses. With headline CPI at 3.8% for the year to June 2026 and landlords' own financing costs up 75 basis points, your next review will hurt more than usual.
A business paying $5,000 per month in rent facing a 4.5% review (CPI plus a margin reflecting the landlord's cost pass-through) will see rent rise by approximately $2,700 per year.
This is not caused by the RBA in the way a loan repricing is, but it is connected. Landlords with variable rate commercial mortgages pass their increased costs through at review, and the CPI component is driven by the same inflation the RBA is fighting. Businesses on fixed escalation clauses, commonly 3% to 4% per annum, get more predictability but the compounding works the same way.
This is the cost nobody puts on a spreadsheet, and it is often the biggest one.
Your suppliers are feeling the same squeeze you are. GoCardless's Pursuing Payments research, which surveyed 500 Australian SMB owners, found 69% had received late payments, up from 63% the year before. Of those, 41% were waiting more than 14 days past due, and almost half said payments were slower than 12 months earlier.
The response from businesses under cash pressure is predictable: they tighten their own terms. Where you once had 30 days, you might now get 14. Some suppliers are moving to payment on delivery or requiring deposits.
For a $2 million revenue business, suppliers shortening terms from 30 days to 14 across even half your supplier base can mean an estimated $15,000 to $25,000 in additional working capital you need to find. That cash comes from your overdraft, at post-hike rates, or from delaying your own payments, which pushes the problem further down the chain.
This is the contagion problem. The same research found 34% of Australian SMBs turned to credit cards or loans in the past 12 months specifically because late payments hit their cash flow. They are borrowing at credit card rates, typically 15% to 22%, to cover gaps created by slow payers, while the cash rate sits at its highest level since 2011. If late payments are already hurting, use our payment reminder email templates to tighten your follow-up and recover cash faster.
Stack the four categories for a typical $2 million revenue, 15-staff Australian SME:
Total estimated annual impact: approximately $31,000 to $45,000.
The lower end assumes modest variable rate exposure and limited supplier disruption. The upper end assumes heavier reliance on working capital facilities and a supply chain where payment terms are actively shortening.
And it did not arrive as one invoice you could see and challenge. It arrived as a slow accumulation across four categories that individually look manageable and collectively change the maths of your business.
For businesses already carrying ATO debt, the rate cycle hits twice. The general interest charge is 11.43% per annum for the July to September 2026 quarter, compounding daily. And since 1 July 2025, GIC is no longer tax deductible.
Carrying $100,000 in ATO debt now costs approximately $11,400 per year in interest, none of which reduces your tax bill. Before the deduction was removed, the effective after-tax cost for a company would have been closer to $8,600. The change makes owing the ATO money roughly a third more expensive in real terms, on top of a GIC rate that has climbed with the cash rate.
The ATO is also collecting harder. Collectable debt reached $54.2 billion per the ATO's 2024-25 annual report, with the national audit office putting small business's share at around $35.9 billion, more than two-thirds of the total. The ATO issued more than 84,500 director penalty notices in 2024-25, a 136% jump on the prior year. If your business is carrying overdue ATO obligations on top of higher commercial lending costs, this is the most expensive debt on your books. Deal with it first.
You cannot control the RBA. You can control how exposed you are and how fast you respond.
Review your debt structure this month. If you hold variable rate facilities, get quotes for fixed alternatives. CommBank expects rates to hold at 4.35% through 2026 with cuts a 2027 story, while 44% of surveyed economists still see another rise this year. If a further increase would create real pressure, fixing buys certainty. If your margins can absorb it, staying variable preserves the upside when cuts eventually arrive. At minimum, know your break costs and your options before the 29 September meeting.
Run a 13-week rolling cash flow forecast. A monthly P&L will not show you the timing problem that kills businesses, particularly now that super leaves with every pay run. Weekly cash flow forecasting exposes the gaps before they become emergencies. Use our cash flow forecast calculator to get started.
Fix your Payday Super process if it is still creaking. The regime has been live since 1 July 2026. If your first pay runs under the new rules involved manual workarounds, late clearing house submissions or contributions that did not land within seven business days, treat that as a red flag now. Penalties for late super are severe, and the ATO can see your timing through Single Touch Payroll.
Contact suppliers before they contact you. If you are a reliable payer, lock in your current payment terms in writing. Suppliers hold 30-day terms for customers with strong payment histories, not for those already stretching to 45 or 60. Negotiate from strength, not desperation.
Check your breakeven point. When costs rise by $31,000 to $45,000, your breakeven revenue shifts. Use our breakeven point calculator to see how much extra revenue you need just to stand still, or how much cost to cut elsewhere to hold margin.
Check your runway. If the compound effect is eating cash, you need to know how many weeks you have. Our when-will-I-run-out-of-money calculator gives you a clear answer from your current burn rate and cash position.
If nobody in your business owns these numbers weekly, that is the actual gap. An bookkeeping support for rba rate hike cost costs a fraction of what this rate cycle is taking, and exists to catch exactly these problems before they compound.
How much does the 2026 RBA rate cycle cost a typical small business?
For a business with $500,000 in variable rate borrowings, the 75 basis point increase since the mid-2025 trough adds approximately $3,750 per year in direct interest. Indirect costs through supplier terms tightening, lease escalation and working capital pressure typically add three to five times the direct interest impact. A $2 million revenue SME with 15 staff can expect a total annual impact of approximately $31,000 to $45,000.
Will the RBA raise rates again in 2026?
Unresolved. The RBA held at 4.35% in June and August 2026 but has said it will lift the cash rate further if needed to bring inflation back to the 2 to 3 per cent band. CommBank forecasts a hold for the rest of 2026 with cuts starting in 2027, while Finder's August survey found 44% of economists still expect at least one more rise this year. The next decision is due on 29 September 2026.
Should I fix my business loan rate at 4.35%?
That depends on your view of where rates head next and your tolerance for uncertainty. If rates rise again, fixing now provides certainty. If they stabilise and eventually fall, you pay a premium for that certainty. The more useful test is cash flow sensitivity: if a further $5,000 to $10,000 in annual interest would create real pressure, fixing acts as insurance. If your margins can absorb another move, staying variable preserves flexibility. This is general information, not advice on your specific facilities.
How does the rate cycle affect my commercial lease?
Most Australian commercial leases include annual reviews linked to CPI or a fixed percentage escalation. Rate hikes do not change your lease terms directly, but they influence CPI, which feeds CPI-linked reviews, and they raise your landlord's own financing costs, which get passed through at the next market review. With headline CPI at 3.8% for the year to June 2026, expect your next review to land at or above that figure.
What is Payday Super and how does it affect my cash flow?
Since 1 July 2026, employers must pay super guarantee with every pay run, and contributions must reach the employee's fund within seven business days of payday. A longer 20 business day window applies to the first contribution for a new employee. The old quarterly float is gone: for a business with a $1 million annual payroll, roughly $30,000 that previously sat in the bank for up to three months now leaves with each pay cycle. Most businesses should expect an estimated $8,000 to $12,000 in additional working capital funding costs in the first year, depending on pay frequency and cash buffers.
How are late payments connected to interest rate increases?
When rates rise, businesses across the supply chain come under cash pressure at the same time. GoCardless research found 69% of Australian SMBs received late payments, up from 63% the year before, with almost half reporting payments slower than 12 months earlier. Suppliers respond by shortening their own terms to protect cash, which means you need more working capital to run the same operation, and that working capital now costs more because overdraft rates have risen too.
What is the ATO general interest charge right now?
The GIC is 11.43% per annum for the July to September 2026 quarter, compounding daily on outstanding balances. It has not been tax deductible since 1 July 2025, so $100,000 of ATO debt costs approximately $11,400 per year with no offsetting deduction.
Is ATO debt enforcement really increasing?
Yes. The ATO issued more than 84,500 director penalty notices in 2024-25, a 136% increase on the prior year, targeting around $5.5 billion in liabilities. Collectable debt reached $54.2 billion, with small business owing roughly two-thirds of it. Directors carrying unpaid PAYG withholding, GST or super guarantee charge can be made personally liable, so overdue ATO obligations should sit at the top of any debt reduction plan.
