Australian households may soon face another financial squeeze. Mortgage holders have already endured a series of interest rate increases, and new forecasts suggest the pressure may not ease anytime soon. Instead, the coming months could bring even higher borrowing costs.
Major Bank Predicts More Rate Hikes
One of Australia’s biggest banks, Westpac, is now forecasting three additional interest rate increases in the coming months. If those hikes occur, the Reserve Bank of Australia’s cash rate could rise to 4.85 per cent by August, a level not seen since the late 2000s, reports 9News.
The prediction follows two interest rate increases already delivered earlier in 2026. At the end of 2025, the cash rate stood at 3.60 per cent, but it has already climbed to 4.15 per cent. For mortgage holders, each increase translates into higher monthly repayments. Even small adjustments can make a noticeable difference for households managing tight budgets.
Fuel Crisis And Global Conflict Driving Inflation
Westpac economists say the ongoing conflict in the Middle East is playing a major role in the changing outlook. The war has disrupted global energy markets, pushing up oil prices and creating uncertainty in fuel supply chains.
Particularly concerning is the disruption around the Strait of Hormuz, one of the world’s most important oil shipping routes. If supply through that region remains restricted, global fuel markets could remain unstable for months.
Higher fuel prices tend to ripple through the entire economy. Transport costs rise, supply chains become more expensive, and businesses often pass those costs onto consumers. That process, economists say, is already pushing inflation higher across Australia.
Inflation Expected To Climb Again
Australia’s most recent inflation figures show prices rising 3.7 per cent over the past year, though those numbers only reflect economic conditions up to February. Economists believe the real impact of the global fuel shock has not yet fully appeared in official data. According to Westpac’s modelling, inflation could peak around 5.4 per cent in the coming months.
Even the government’s decision to halve the fuel excise temporarily may only soften the increase rather than stop it entirely. Higher fuel costs also affect products beyond petrol itself. Aviation fuel, plastics and other oil-based materials can become more expensive, pushing prices up across a wide range of goods.
Economic Growth Could Slow
If interest rates rise further, the broader economy could begin to feel the strain. Westpac predicts that higher borrowing costs may lead to slower economic growth and a possible increase in unemployment. Joblessness could rise to around five per cent if economic activity cools significantly.
For households, that combination — rising prices, higher mortgage repayments and weaker economic growth — creates a difficult financial environment. Many Australians are already adjusting spending habits, cutting back on non-essential purchases or delaying major financial decisions.
More Pressure Ahead For Borrowers
The Reserve Bank faces a complicated balancing act. Raising interest rates can slow inflation, but it also increases financial stress for households and businesses. If inflation continues rising due to global energy prices, policymakers may feel they have little choice but to tighten monetary policy further.
For millions of Australians with mortgages, the months ahead could bring yet another test of household finances. And for now, the message from economists is clear: the interest rate cycle may not be finished yet.
