The Reserve Bank's decision to leave the cash rate at 4.35 per cent will be felt well beyond Australia's capital cities.

Regional households, businesses, property investors, builders and farmers are all exposed to interest rates, although sometimes in quite different ways.

The August decision means there will be no additional RBA-driven increase this month.

But the RBA has not declared victory over inflation.

Another increase remains possible.

Regional mortgage holders get a reprieve

Regional property prices are generally lower than those in Sydney and some other capital-city markets, but that does not mean regional households are immune from mortgage stress.

Many regional property markets experienced substantial increases during and after the pandemic.

Buyers who entered those markets with large mortgages can now face much higher repayments than they originally expected.

Holding the cash rate at 4.35 per cent prevents another immediate increase attributable to the RBA.

It does not reduce existing repayments.

The flow-on to Main Street

Interest rates can quickly become a regional business story.

When households devote more income to mortgage repayments, they have less money available elsewhere.

The consequences can appear in cafés, restaurants, clothing stores, furniture retailers, tourism businesses and other discretionary sectors.

A rate rise aimed at reducing national inflation can therefore eventually result in fewer customers walking through the door of a business in a regional town.

That is monetary policy transmission in everyday life.

Regional business borrowing

Regional SMEs face the same fundamental financing challenge as metropolitan businesses.

The RBA cash rate is 4.35 per cent, but commercial borrowers generally pay substantially more.

Banks determine their own lending rates according to funding costs and borrower risk.

There is no requirement for a bank to provide a home or business loan at the RBA cash rate.

Regional businesses should consequently compare financing carefully.

A difference of even one percentage point can become significant over a large loan and a long period.

Housing and construction

Higher rates also affect regional housing development.

Developers face increased financing costs.

Builders can experience softer demand.

Potential purchasers can borrow less.

Investors may decide that rental yields no longer adequately compensate for financing costs and risk.

That can slow the creation of new housing at precisely the time many regional communities remain concerned about accommodation shortages.

Interest rates therefore solve one economic problem while potentially exacerbating another.

Inflation is still running too high

The RBA expects inflation to return to around the midpoint of its target range only in late 2027.

That helps explain why Governor Michele Bullock is unwilling to declare the tightening cycle finished.

International energy prices remain another risk.

Regional Australia is particularly exposed to fuel because distances are greater and public transport alternatives can be limited.

Higher fuel costs affect households directly and increase the cost of moving goods throughout regional Australia.

What happens in September?

The next RBA decision is scheduled for 29 September.

Inflation will be critical, but the Board will also assess employment, wages, consumer spending, housing, business conditions and international developments.

If the economy slows and inflation follows, the case for another increase weakens.

If inflation remains stubborn, another rate increase remains possible.

The Regional Times View

Interest rates are national policy, but their consequences are intensely local.

They appear in the mortgage payment of a family in a regional town.

They influence whether a local business buys another vehicle.

They affect whether a developer proceeds with housing.

And they help determine how much money households have left to spend on Main Street.

The RBA held at 4.35 per cent.

For regional Australia, the more important question is how long it stays there — and whether the next movement is finally down or once again up.
