For Australian businesses, the Reserve Bank's decision to leave the cash rate at 4.35 per cent provides stability — but not necessarily relief.

The RBA's Monetary Policy Board has decided against another immediate increase after three rate rises during 2026.

For businesses carrying debt, that removes the prospect of another immediate RBA-driven increase in financing costs.

But 4.35 per cent remains a restrictive cash rate, and the interest rates actually charged on commercial loans, overdrafts, equipment finance and commercial property debt can be considerably higher.

The important question for business is therefore not simply whether the RBA moved rates this month.

It is how long expensive money will remain part of the operating environment.

The RBA has paused, not surrendered

Governor Michele Bullock has made clear that another increase remains possible if inflation does not behave as the RBA expects.

That matters for business planning.

A company considering borrowing to purchase equipment, acquire premises, increase inventory or expand operations cannot safely construct its business case around an assumption that interest rates will shortly fall.

The RBA expects inflation to return to around the midpoint of its 2–3 per cent target range only in late 2027.

Higher borrowing costs could therefore remain part of the commercial landscape for some time.

The double impact on business

Interest rates can hit businesses twice.

The first impact is direct.

A business with variable-rate debt can face higher repayments as monetary policy tightens.

The second can be even more important.

Customers with mortgages also have higher repayments.

A household spending hundreds of additional dollars each month servicing its home loan has less money available for restaurants, clothing, entertainment, travel, home improvements and other discretionary purchases.

The RBA does not need every Australian business to borrow money for interest rates to affect it.

Reducing household spending is one of the mechanisms through which monetary policy works.

Cash-rich businesses are in a different position

Higher rates do not hurt everyone equally.

Businesses with significant cash reserves and little debt may receive substantially better returns on deposits than they did during the ultra-low-rate era.

That creates a significant divergence.

A heavily leveraged company may regard the present environment as painful.

A conservatively financed competitor may regard it as an opportunity.

That difference can become particularly important when businesses compete to acquire assets or other companies.

Should businesses postpone investment?

Not necessarily.

The RBA itself notes that business debt and investment remain strong.

A productive investment can still make sense at higher interest rates.

The hurdle is simply higher.

Businesses need to examine whether the expected return from an investment comfortably exceeds its financing cost and associated risk.

Borrowing at a high rate to fund an asset generating only a marginal return is considerably harder to justify.

An investment that increases productivity, reduces labour requirements or creates substantial additional revenue can be a very different proposition.

Banks do not have to lend at 4.35%

The RBA cash rate is not a mandated business lending rate.

Banks and other lenders determine their own commercial lending rates.

They consider funding costs, risk, security, the financial position of the borrower, loan structure, regulatory requirements and their desired margin.

Two businesses borrowing the same amount can consequently receive very different offers.

That makes shopping for finance particularly important when money is expensive.

The RBA establishes an enormously influential benchmark.

It does not determine the price of every business loan in Australia.

Inflation remains the central issue

Businesses are also experiencing inflation directly.

Fuel, freight, insurance, wages, rents, electricity, imported products and other inputs can increase operating costs.

Businesses then face an unpleasant choice.

Absorb those increases and accept lower margins, or pass them to customers and risk losing sales.

The RBA is trying to prevent individual price increases from developing into persistent economy-wide inflation.

But monetary policy cannot directly solve many of the causes.

Higher Australian interest rates cannot produce oil, end geopolitical conflicts or remove international shipping disruptions.

They can reduce Australian demand.

That is the blunt power of monetary policy.

What should businesses watch before September?

The next RBA decision is scheduled for 29 September.

Businesses should watch inflation, consumer spending, employment, wages, fuel and energy prices, housing activity and international developments.

Particularly important will be evidence about whether the previous rate increases are slowing demand sufficiently.

If inflation continues to resist the RBA's efforts, another increase remains possible.

If the economy weakens materially and inflation subsides, the case for further tightening diminishes.

The Business Times View

The August RBA decision gives Australian businesses something valuable: a period of stability.

It does not give them cheap money.

Businesses should therefore continue planning around the interest-rate environment that exists rather than the lower rates they hope may eventually arrive.

For strong businesses, this environment can also create opportunity.

Competitors carrying excessive debt become vulnerable. Assets may become cheaper. Cash becomes more valuable. Productivity-enhancing investment becomes increasingly important.

The RBA has paused.

Australian business should use that pause wisely.
