Australia's inflation problem is a hot topic, and it's time to uncover what's really going on. The Reserve Bank of Australia (RBA) has taken a bold step to tackle it, but will it work?
This week, the RBA decided to increase interest rates for the first time in two years, and the reason is clear: inflation is on the rise. The central bank's monetary policy board unanimously voted to raise the cash rate by 0.25 percentage points, aiming to slow down spending and bring inflation under control.
But here's where it gets controversial: this decision could impact borrowers significantly. RBA Governor Michelle Bullock acknowledged this, stating, "I know it's not what mortgage holders want to hear, but it's necessary for the economy's health."
So, what exactly is inflation, and how does it affect us? Let's dive in.
Inflation Explained:
Inflation is the rate at which consumer goods prices increase. It's measured using the Consumer Price Index (CPI), published by the Australian Bureau of Statistics. The CPI is released monthly, with an additional quarterly update.
The RBA aims to keep inflation within a target band of 2-3%. Recently, inflation has been creeping up, with headline CPI inflation reaching 3.8% in December 2025, up from 3.4% in November. Even underlying inflation measures, which exclude volatile price swings like petrol, have increased, with trimmed mean inflation at 3.3%.
The RBA's monetary policy board meets eight times a year to decide on the cash rate. They use it to cool down spending when prices rise too fast or to support the economy during weak growth periods.
With the "underlying momentum of inflation" being too strong, the board unanimously voted to raise rates.
Understanding the Cash Rate:
The cash rate is the key interest rate set by the RBA. It influences the cost of borrowing for banks, which then affects the interest rates we pay and earn on things like home loans and savings accounts.
When the cash rate increases, loan repayments can rise, especially for those with variable-rate mortgages. On the other hand, people with savings might see higher interest rates on their bank accounts.
What's Driving High Inflation?
The RBA cited several key reasons for the higher inflation, including growing private demand, capacity pressures, and a tight labor market.
AMP Chief Economist Shane Oliver explained that rising private demand refers to Australian consumers' spending on homes, construction, and investment.
"Capacity pressures" relate to the balance between demand and supply in the economy. When demand for resources is high but output is constrained, it can drive inflation.
Jack Thrower, a senior economist at the Australia Institute, said, "If more demand appears in the economy, but we don't have the resources to expand production, businesses will put up their prices. That's the concern for the RBA."
To address capacity constraints, both Thrower and Oliver emphasized the importance of productivity.
"Productivity is about using our resources efficiently. We can increase it by working smarter, building more factories, or expanding our workforce," Thrower explained.
Oliver warned that a tight labor market, while good for workers, could lead to upward pressure on inflation as workers demand higher wages.
Other Factors:
Thrower mentioned that the RBA acknowledged some "one-off" and "unusual" events, like expenditure on overseas holidays and the withdrawal of electricity price subsidies, but these aren't major concerns.
Meg Elkins, an associate professor of economics at RMIT University, described the December inflation rate as "unsurprising," citing factors like food, accommodation, and cultural activities, especially with artists returning and ticket prices rising.
She explained consumer behavior in 2025 as driven by "rational expectations." People spent more when rates were expected to continue falling, and now that they're told to tighten their belts, they'll likely spend less.
What Can You Do About It?
According to Thrower, not much. He believes it's a macroeconomic problem affecting the entire economy, making it challenging for individuals to make a significant impact.
"Inflation is about businesses increasing their prices. In a market economy like Australia's, firms aim to maximize profits, and that often means charging higher prices for their goods, especially with limited market competition in sectors like groceries, insurance, and airlines,"
Elkins suggests shopping around and supporting the right companies. She emphasizes the importance of strategic spending and sending a signal to businesses.
"The interest rate hike affects different groups unequally. It's almost like a two-tier economy, with self-funded retirees on one side and renters or mortgage holders on the other,"
She adds that the rate hike is a signal to the market that "consumers need to slow down."
Michelle Bullock described the rate hike as a "blunt instrument" to curb inflation, and its impact on households is a concern.
"For mortgage holders, this is a tough outcome. But if inflation remains high, it's not great for anyone. Getting inflation under control is the ultimate goal, and interest rates are our tool,"
Elkins believes the RBA's message to average Australians is clear: "Spend less, save more, and be cautious about asking for big wage increases."
