Interest rate rise and your business loan: a 4-step check before the next RBA decision

If you carry business debt, 2026 has been a year of letters from your lender. The Reserve Bank lifted the cash rate in February, March, May and again on 29 September, taking it from 3.60% to 4.60%, the highest it has been since 2011. That’s a full percentage point in eight months.

The question most owners are asking isn’t “why?” It’s “what does this mean for my loan, and should I do something about it now?” This guide walks you through a four-step check you can do in an afternoon with your bank statements and loan documents. At the end you’ll know whether to hold, restructure or refinance, and you’ll have that answer before the RBA’s next decision on 3 November.

What did the RBA actually do, and is another rise coming?

In its 29 September statement, the Monetary Policy Board said some of the “upside risks flagged in August are materialising”, pointing to higher fuel prices flowing through to other goods and services. It lifted the cash rate target by 0.25 percentage points to 4.60%.

The minutes of that meeting are worth a skim. Two lines matter for business borrowers:

• Market pricing at the time pointed to roughly another 0.15 percentage points of tightening by the end of the year, and more in the first half of 2027.
• The board said it would keep “increasing the cash rate target further if required”, and noted business conditions “were more challenging in certain sectors”.

Nobody can tell you what happens on 3 November, and you don’t need to guess. The smart move is to plan as if there’s one more rise and see whether your business still breathes comfortably. If it does, you can stop worrying. If it doesn’t, you’ve found out with time to act.

Step 1: Which of your debts actually move?

This is where many owners overestimate the damage, or underestimate it. A cash rate rise doesn’t touch every loan.

Grab a sheet of paper and list every facility the business pays. Then mark each one:

Type of debt	Usually moves with rate rises?
Business overdraft	Yes, variable
Business line of credit	Usually variable
Property-secured business loan	Often variable, sometimes fixed for a period
Unsecured term loan	Often fixed for the term
Equipment or vehicle finance	Usually fixed for the term
Fixed-period loan coming off its fixed term	Yes, it resets to the current variable price

The last row is the sleeper. If you fixed a loan two or three years ago and the fixed period ends in the next six months, your repayments could jump by much more than one quarter’s rise. Circle it.

Coaching question: how much of your total debt is variable, in dollars? Write it down. That’s the number every rise works on.

Step 2: Repayment headroom, tested against your quietest month

Averages hide trouble. Your test month should be the quietest month in the past 12, not a typical one.

1. Find the quietest month’s deposits. Look at your business bank statements and pick the lowest month of takings.
2. Add up your monthly repayments across every facility, using the new amounts after the September rise.
3. Add one more rise. As a rough guide, each 0.25 percentage point on variable debt adds about $2,500 a year in interest for every $1m borrowed. That’s roughly $1,000 a year, or about $83 a month, on $400k.
4. Work out the share: repayments (with the extra rise) ÷ quietest month’s deposits.

Then score yourself honestly:

• Green: after wages, suppliers, rent, tax set-asides and repayments, the quiet month still leaves something over. Holding is probably fine.
• Amber: the quiet month only just covers everything, or you’d have to delay a BAS payment or a supplier to make it work.
• Red: the quiet month already runs short, or the extra rise pushes it under.

If you’re amber or red, keep going. This test exists so you find out on paper, not when a direct debit bounces.

Step 3: What does the rise do to your cash runway?

Headroom tells you about one month. Runway tells you how long the business could keep paying its bills if trade slowed. Our cash runway guide has the full method, but the short version is: available cash (after tax already owed) ÷ weekly costs.

Rerun that calculation with your higher repayments included. A rise that adds a few hundred dollars a month might look small, but if your runway was already sitting at six or seven weeks, it can quietly knock a week off. business.gov.au suggests using a cash flow statement to forecast ahead and plan for payments, and a 13-week view is the right horizon here: it captures the next RBA decision, the December BAS quarter and the January slowdown many sectors feel.

What you’re looking for: your lowest week in the next 13. If it dips below zero, or below the buffer you’d normally hold, that’s your signal to act before it arrives.

A worked example: one business, two different answers

This is an illustrative example, not a real client.

A regional electrical contractor has three debts: a $400k variable property-secured loan used to buy the workshop, a $60k line of credit, and a fixed-term vehicle loan on two vans.

• Step 1: only the property-secured loan and the line of credit move. That’s $460k of variable debt. The van loan is fixed, so it hasn’t changed.
• Step 2: the four rises this year have added roughly $4,600 a year in interest across those two facilities, about $380 a month. One more 0.25 point rise would add around $96 a month on top. Their quietest month (January) still covers everything with a small margin: amber leaning green.
• Step 3: runway is about nine weeks, falling to just over eight with the higher repayments.

The answer: hold, but tidy up. The owner keeps the property loan where it is, but notices the line of credit has been drawn to the limit for most of the year. It’s no longer a buffer. It’s become long-term debt at short-term repayment patterns. They plan to talk about rolling the drawn amount into the longer-term property-secured loan so the line of credit is free again for genuine gaps.

Now change one detail: the workshop loan was fixed and the fixed period ends in February. Suddenly a large part of that $400k resets to the current variable price all at once. Same business, different answer. That owner should be talking to their lender, or looking at options, now, while bank statements look strong and there’s no deadline breathing down their neck.

If your check is landing in amber or red, it’s worth seeing what structure might suit you before the next RBA decision, rather than after it.

Step 4: Hold, restructure or refinance?

This is the decision the first three steps set up. Here’s how to read your result:

Hold

You’re green on headroom, your runway is healthy, and your loans already match their purpose (long-term assets on long-term debt). Keep an eye on the November and December decisions, and recheck your numbers if a fixed period is ending.

Restructure with your existing lender

You’re amber, or one facility is clearly the wrong shape. Common fixes include extending a term to lower repayments, moving a permanently drawn line of credit into a term loan, or a short interest-only period while you lift prices or trim costs. Banks that have adopted the Banking Code of Practice say they’ll work with small business customers in financial difficulty to find a sustainable solution, including interest-only periods, term extensions and deferrals. The key is to ask early.

Refinance

You’re amber or red and your current lender can’t or won’t restructure, or you have several debts that would work better as one. Refinancing can also make sense if you’ve built up equity in property that could replace more expensive short-term debt. Our refinancing page covers when consolidating debts makes sense and when it just moves the problem around.

Common mistakes when rates are rising

• Refinancing to bet on the forecast. Switching lenders because you expect rates to fall (or rise) next year is speculation. Decide on structure, fit and total cost.
• Forgetting break costs. Leaving a fixed loan early can come with break costs. Ask for the figure in writing before you compare.
• Stretching the term without counting the cost. Smaller repayments over a longer term usually mean more interest in total. That trade can still be right, but make it on purpose. Our good debt vs bad debt self-test helps here.
• Using the line of credit to make loan repayments. If you’re borrowing to service borrowing, something in the business needs to change too: prices, costs or the structure of the debt.
• Waiting for a missed payment. Lenders have more room to help, and you have more options, while your account is still up to date.

Is the rate rise squeezing your business? Let’s look at the right structure together

Rising rates don’t mean your business is in trouble. They mean the shape of your debt matters more than it did a year ago. Plenty of owners come out of this check realising one facility is doing the wrong job, and a simple restructure frees up both cash and peace of mind.

If you’d like a second opinion on whether to hold, restructure or refinance, we’re happy to help. Our enquiry takes about 60 seconds, and checking your options won’t touch your credit file — there’s no credit check when you first enquire. We won’t fire your details off to a pile of lenders either, so there’ll be no flood of calls. A real person reads your answers, looks at your debts, your takings and your timing, and calls you to talk it through.

Please fill the form in accurately: what you owe and to whom, roughly what you’d like to change, and your typical monthly deposits. Getting those right means we can match you with the right option the first time. Prefer to explore on your own first? The 2-minute funding profile ranks the options that suit your stage and goal.
