Rising interest rates can affect far more than household mortgages. For Australian business owners, higher rates can increase borrowing costs, reduce available cash flow and make it more difficult to fund growth.

In The CEO Breakdown discussion, John Saade highlighted the potential impact of higher interest rates on businesses and the broader Australian economy. With interest rates affecting mortgages, business loans and overall borrowing capacity, businesses carrying significant debt may face additional pressure when rates rise.

The Reserve Bank of Australia (RBA) currently has the cash rate target at 4.35%, effective from 12 August 2026, with the next scheduled monetary policy announcement on 29 September 2026.

For business owners, understanding how interest rate changes flow through to the business can help with better cash flow management and financial planning.

How Do Rising Interest Rates Affect Businesses?

When the RBA increases the cash rate, borrowing costs across the economy can increase. Banks and other lenders may pass higher funding costs through to borrowers through higher lending rates.

The RBA has noted that changes in the cash rate influence broader financial conditions, including the interest rates faced by businesses and households.

For a business with debt, this can mean higher repayments without any corresponding increase in revenue.

For example, a business with a variable-rate loan may see its interest expense increase following a rate rise. While one increase may appear manageable, several increases can significantly affect annual financing costs.

This is particularly important for businesses that rely heavily on debt to fund:

• Property purchases
• Equipment and machinery
• Business acquisitions
• Inventory
• Expansion
• Working capital
• Commercial property development

Higher Interest Costs Can Reduce Business Cash Flow

Cash flow is one of the biggest areas of concern when interest rates rise.

A business may remain profitable on paper but still experience cash flow pressure if more of its available cash is being used to service debt.

For example, if a business has substantial loans and its interest rate increases, the additional interest expense may reduce the amount of cash available for:

• Employee wages
• Supplier payments
• Tax obligations
• Stock purchases
• Marketing
• Equipment
• Business expansion
• Owner drawings

The RBA’s Financial Stability Review has noted that cash flow pressures on household and business borrowers can increase when financial conditions tighten, although most businesses were considered well placed to manage those pressures at the time of its March 2026 assessment.

The impact will vary significantly between businesses depending on their debt levels, revenue, cash reserves and ability to increase prices.

Rising Rates Can Make Business Debt More Expensive

Businesses often use debt as part of their growth strategy.

Borrowing can allow a business to purchase assets, expand into new locations or invest before it has accumulated enough cash to fund the project itself.

However, debt becomes more expensive when interest rates increase.

Consider a business with a $1 million loan. Even a 1 percentage point increase in the interest rate could represent an additional $10,000 in annual interest expense, assuming the full $1 million balance remains outstanding and ignoring principal repayments.

That additional cost needs to come from somewhere.

If revenue does not increase, the business may need to reduce other expenses, increase prices, use cash reserves or slow down its investment plans.

Higher Rates Can Affect Business Growth

One of the reasons interest rates matter beyond the cost of a loan is that they can influence business decisions.

When borrowing becomes more expensive, business owners may delay major investments.

For example, a business considering:

• Opening another location
• Purchasing commercial property
• Buying new equipment
• Acquiring another business
• Hiring additional employees
• Increasing inventory

may reconsider the timing of that investment if the expected return is no longer attractive compared with the cost of finance.

This can make business growth more difficult, particularly for businesses that rely heavily on borrowed capital.

What Happens When Debt and Revenue Move in Opposite Directions?

The most significant problem can occur when rising interest rates happen at the same time as falling revenue.

Imagine a business experiencing weaker customer demand while its loan repayments are increasing.

The business could face a double pressure:

Lower revenue + higher financing costs = greater cash flow pressure.

This is why business owners should not only look at whether their business is profitable.

They should also understand:

• How much debt the business has
• When loans need to be refinanced
• Whether interest rates are fixed or variable
• How much interest the business currently pays
• How much cash is available
• How quickly expenses can be reduced
• How sensitive profits are to changes in interest rates

How Can Business Owners Prepare for Higher Interest Rates?

Business owners cannot control the RBA’s decisions, but they can improve their financial resilience.

1. Review Your Existing Debt

Start by reviewing every business loan and financing arrangement.

Understand the interest rate, repayment schedule, loan term, and whether the rate is fixed or variable.

This can help identify which debts could become more expensive if rates rise further.

2. Stress-Test Your Cash Flow

Consider what would happen if your interest rate increased by another 1% or 2%.

Would the business still have enough cash to cover:

• Wages?
• Suppliers?
• Tax?
• Loan repayments?
• Rent?
• Essential operating costs?

Cash flow forecasting can help identify potential problems before they become urgent.

3. Build a Cash Buffer

A healthy cash reserve can provide breathing room when business conditions become more difficult.

Rather than using every available dollar for expansion, consider whether maintaining an appropriate cash buffer could provide greater financial security.

4. Review Pricing

If financing costs, wages, rent, and other operating expenses increase, businesses may need to review their pricing.

However, price increases should be based on the business’s market position, customer demand and overall cost structure.

5. Avoid Taking on Unnecessary Debt

Debt can be useful when it funds productive investment, but taking on additional borrowing simply because finance is available can increase risk.

Business owners should consider whether the expected return from new borrowing justifies the additional interest expense.

Why Business Owners Should Look Beyond the Interest Rate

Interest rates are only one part of a business’s financial position.

John Saade’s discussion also highlights how businesses can become vulnerable when debt, weak cash flow, and broader economic pressures occur at the same time.

A business with strong cash reserves, manageable debt and reliable revenue may be able to withstand higher rates.

Another business with high debt, narrow margins and inconsistent cash flow may experience significant financial pressure from the same rate increase.

The important question is therefore not simply “Will interest rates rise?”

It is:

“How prepared is my business if they do?”

Final Thoughts

Rising interest rates can affect Australian businesses through higher loan repayments, increased financing costs, reduced cash flow and slower investment.

The impact will depend on the amount and type of debt a business carries, its revenue, profit margins, cash reserves and ability to adapt.

With the RBA’s cash rate currently at 4.35%, businesses should understand how sensitive their finances are to further changes in borrowing costs.

Reviewing debt, forecasting cash flow, and stress-testing different interest rate scenarios can help business owners make more informed decisions.

Most importantly, business owners should not wait until cash flow becomes a problem before reviewing their financial position.

Frequently Asked Questions About Rising Interest Rates and Business Debt

How do rising interest rates affect business cash flow?

Higher interest rates can increase loan repayments and financing costs, reducing the amount of cash available for wages, suppliers, tax, investment and other business expenses.

Are businesses with variable-rate loans more exposed to interest rate rises?

Generally, variable-rate borrowers can be affected more quickly because changes in lending rates may increase their interest costs and repayments.

Should my business pay down debt when interest rates rise?

It depends on the business’s cash reserves, loan terms, investment opportunities, and overall financial position. Paying down debt can reduce future interest costs, but retaining sufficient working capital is also important.

How can I prepare my business for higher interest rates?

Review your debt, forecast cash flow, build an appropriate cash buffer and stress-test your finances against higher interest rates. Professional financial advice can also help identify appropriate strategies.

Can rising interest rates affect business growth?

Yes. Higher borrowing costs can make investments such as expansion, equipment purchases, acquisitions and property purchases more expensive, potentially causing businesses to delay growth plans.

Should I review my business loans with my accountant?

Yes. Your accountant can help you understand how financing costs affect profitability and cash flow and help you assess the financial implications of different scenarios.
