You’re not alone if mornings start with checking the Middle East-fuelled fuel price, sweating payment chases, and wondering if that next rate hike will be the one that breaks you.
Most small business owners are right there with you at the moment.
Rising inflation and the Reserve Bank of Australia’s (RBA’s) March 2026 official cash rate target hike to 4.10% (increase of 25 base points) are squeezing Aussie SMEs with higher operating costs and tighter cash flow.
The question is: what can you do about it? Here’s a look at what the current economy is costing small businesses and how you can protect your margins.
The cost of interest and cash rate hikes
A ScaleSuite cost analysis suggests that many SMEs are facing $29,000 to $43,000 in extra annual expenses for a typical $2 million turnover business.
Here’s how these costs stack up against key pressure points:
- Equipment and asset finance – A $500,000 variable rate loan, which would have been around 5.75% at the mid‑2025 trough, is now closer to 6.25% or higher. That adds roughly $2,500 per year in extra interest and could go up to $3,750 if another rate rise occurs.
- Overdraft and working capital pressure – Variable overdraft rates track cash rate moves closely. While direct interest costs rise incrementally, changes like the new Payday Super rules mean cash is needed sooner, increasing reliance on overdrafts. This added working capital pressure can represent around $9,000 to $13,000 in extra annual costs.
- Commercial lease escalations – Most leases include CPI‑linked reviews. With headline inflation around 3.8%, a business paying $5,000/month in rent can expect rent increases of about $2,700 a year.
- Supplier terms tightening and cash flow squeeze – Late payments and tighter supplier terms are a big hidden pressure. As suppliers shorten terms, your working capital needs rise. This can add an estimated $15,000 to $25,000 in working capital costs.
Taken together, these costs total $29K–$43K, or about 1.5–2% of turnover. For many SMEs, that’s enough to wipe out profit entirely.
How to protect your margins
Rising inflation and rate hikes don’t have to shrink your profits if you act fast and smart. Here are some actions you can take right now.
Start with projections
Don’t wait to see how rising costs hit your business. Model it so you can act.
The Middle East crisis, fuel spikes and rate hikes are creating volatility, but a simple projection can show where the real pain points are. It will help you make a decision based on real numbers, not panic.
- Stress-test your cash flow – Forecast fuel, energy and interest costs under different price scenarios. This will show where you need to act fast and whether you need to tap your savings account or other reserves.
- Model price changes – Use your projection to test the impact of price changes on low-elasticity items. This will help you protect margins without guessing.
- Plan debt repayments – Layer your projections with upcoming loan repayments and overdraft interest. Know when to refinance or pay down high-interest credit first.

As business advisors, we can run financial projections for you, including complicated modelling, scenario testing and number-crunching.
Take control of cash flow
Cash is king in small business, and late payments are a hidden drain.
- Chase payments early – Run a payment report in Xero or MYOB to identify your top 10 late payers. Send your debtors email reminders on Day 7 and give them a phone call on Day 14. Cutting your usual 78-hour chase time by 40% can save $10K+ versus taking credit card debt.
- Split your invoice terms – Offer better terms for Day 7 payment, and charge 2% on Day 60. This will help encourage those late payers to pay up faster.
- Sort out ATO debt now – Call the tax office to set up a payment plan before automated collections kick in.
Slash big costs in these financial conditions
Extra dollars often leak out of energy, fuel and leases. They’re also where you can recover them.
Right now, global events are pushing costs higher: oil prices are volatile thanks to the Middle East crisis, and electricity and fuel bills are climbing across the board.
- Run an energy audit –Compare business electricity plans (Google ‘business electricity comparison [your postcode]’, switch to time-of-use tariffs, and stagger big loads. With careful planning, you could save 20–30%.
- Fuel hacks – Route-optimise deliveries (cuts 15% diesel spend), bulk-buy fuel cards, or negotiate fleet rates. With fuel prices up 15–30% recently, even small changes make a real difference.
- Talk to your landlord – Ask for a 6-month CPI freeze on leases, citing your loyalty. Even partial success reduces fixed costs when every dollar counts.

Make smart debt moves
By looking at your current debt and finding better ways to manage it, you can stay ahead of the next RBA hike.
- Refinance now – Talk to your bank to review rates and to determine if locking in rates now will save you money or provide some certainty.
- Prioritise repayments: Credit cards first (highest rates), then variable loans, then equipment finance.
- Invoice financing – Take up to 80% advance on receivables at 1.5% monthly – often cheaper than overdraft for seasonal peaks.

Revisit your pricing
Just because costs are rising, it doesn’t mean your profits have to be shrinking. What it does mean is that you need to price strategically – but carefully. You don’t want to scare off clients or customers with big increases.
- Test a small increase – Try a small increase on select products or services first. Run it with 20% of your customers for a week to see the response.
- Prioritise high-margin items – Increase prices a little more on ‘must-haves’ while holding prices on loss-leader items. This will protect your overall profitability without losing volume.
- Bundle strategically – Combine essentials into a pack. Bundles often soften price increases and increase perceived value, making it easier to pass through costs.
Extra steps to keep margins safe
In addition to the advice above, here are some small operational changes you can make that add up:
- Inventory management – Reduce overstock, negotiate just-in-time delivery or bundle slow-moving products.
- Supplier terms – Ask for longer payment terms or early-payment discounts, lock in fixed rates for fuel/raw materials.
- Operational efficiency – Audit staff schedules, automate repetitive tasks, streamline delivery routes.
- Scenario planning – Build contingency cash reserves based on worst-case fuel, energy and interest scenarios.
What is scenario planning?
Scenario planning is a key part of projections – and something we also deliver. It takes your projections and models multiple ‘what if’ outcomes: best case, worst case, and everything in between.
Stop sweating; start acting
You can’t control the RBA’s interest rate decision or fuel prices, but you can control what happens next in your business.
Enough checking the news and sweating the late payers. Even if you grab just one move from above – chase those Day 7 invoices, test that small price bump, or lock in fixed-interest-rate debt – and run with it this week.
