RBA independence may have created an accountability gap. Governments receive the political benefits of spending and tax decisions, while the RBA frequently bears the political cost of controlling their inflationary consequences.

Most Australians know who to blame when mortgage repayments rise.

The Reserve Bank raises interest rates, banks pass on the increase, and households immediately feel the impact. When inflation is high and borrowing costs are rising, public frustration often lands squarely on the Reserve Bank of Australia (RBA).

But is the institution administering the pain always responsible for creating the conditions that made it necessary?

Inflation is not determined by monetary policy alone. Government spending, taxation, budget deficits, labour market conditions, productivity growth and global economic shocks all influence inflation outcomes. Yet public debate frequently treats inflation management as though it rests solely with the RBA.

This raises an important question: has Australia’s system of central-bank independence created an accountability gap?

This is not an argument against an independent RBA. The Bank’s independence protects monetary policy from short-term political pressures and remains a cornerstone of Australia’s economic framework. Rather, the question is whether that framework concentrates public accountability on the RBA while reducing scrutiny of the fiscal decisions that can also influence inflation.

History provides some compelling examples.

Why RBA Independence Matters

The RBA’s independence exists for good reason.

Politicians face elections. Central bankers do not.

Australia’s monetary policy framework gives the RBA responsibility for maintaining inflation between 2 and 3 per cent on average over time. The Bank is expected to make decisions that support long-term economic stability, even when those decisions are unpopular.

The challenge is that inflation is rarely created by monetary conditions alone.

Government budgets can either complement the RBA’s efforts or make its task more difficult. When fiscal and monetary policy are aligned, inflation control becomes easier. When they move in different directions, tensions can emerge.

The following case studies examine periods when fiscal and monetary policy appeared to be pulling in opposite directions.

Case Study 1: The Howard-Costello Budget and the RBA’s Inflation Fight (2006-2007)

By 2007, Australia was enjoying the benefits of the mining boom. Economic growth was strong, unemployment was exceptionally low, and inflationary pressures were beginning to emerge.

The Commonwealth Government acknowledged this reality in the 2007-08 Budget, noting that Australia was “as close to full employment as it has been for over 30 years” while also identifying capacity constraints within the economy. ¹

Despite these conditions, the Government announced approximately $31.5 billion in personal income tax reductions over four years. The Budget stated that these reforms would increase disposable incomes and support workforce participation. ²

At the same time, the RBA was attempting to restrain inflation.

In the Governor’s Foreword to the 2007 Annual Report, Glenn Stevens noted:

“Monetary policy was tightened somewhat in the first half of the financial year and again in August 2007, as the Board acted to keep inflation close to the target.” ³

This created a notable policy tension.

While fiscal policy increased household disposable income, monetary policy sought to slow spending through higher borrowing costs.

Reasonable observers may disagree about whether either institution made the wrong decision. However, it is difficult to deny that the two arms of macroeconomic policy were exerting pressure in different directions.

For most Australians, the most visible consequence was not the tax relief announced in Budget Paper No. 1.

It was the increase in their mortgage repayments.

This highlights a recurring feature of economic policymaking: fiscal policy can contribute to inflationary conditions, but monetary policy is often the mechanism through which households experience the response.

Case Study 2: Inflation, Interest Rates and Cost-of-Living Relief (2022-2024)

Australia’s post-pandemic inflation surge presented policymakers with one of the most difficult economic environments in decades.

Inflation rose to levels not seen for a generation. Supply-chain disruptions, labour shortages, strong consumer demand and rising energy prices all contributed to sustained price pressures.

The RBA responded with one of the fastest interest-rate tightening cycles in modern Australian history.

By May 2024, the Bank remained concerned about inflation. It stated that inflation was “falling more gradually than expected” and emphasised that returning inflation to target remained its highest priority ⁴. The Bank also stated that higher interest rates were expected to bring demand into better balance with supply and noted that aggregate demand remained above the economy’s productive capacity ⁵.

At the same time, governments faced intense political pressure to relieve cost-of-living pressures.

The Commonwealth’s 2024-25 Budget included:

• Energy bill relief;
• Increases to Commonwealth Rent Assistance;
• Personal income tax changes;
• Other targeted household support measures. ⁶

Importantly, the Government did not present these measures as inflationary stimulus. Instead, it argued they would help reduce inflation while providing household relief. The Budget specifically stated that cost-of-living measures would lower headline inflation in the near term. ⁷

The available evidence suggests that at least some measures achieved that objective.

The RBA estimated that government electricity rebates reduced headline inflation by around 0.3 percentage points in the March quarter of 2024. ⁸

However, the same RBA documents also observed that public spending continued to support economic activity and that overall demand remained stronger than the economy’s supply capacity. ⁹

This reveals a more nuanced tension than the 2007 example.

The Government sought to shield households from rising living costs. The RBA sought to bring inflation back to target. Both objectives were defensible. Yet they operated through different channels and potentially created competing effects.

What happened politically is perhaps more interesting.

Media coverage focused overwhelmingly on:

• Interest-rate decisions;
• Mortgage stress;
• Statements from the RBA Governor;
• Predictions of future rate increases.

Far less attention was given to the interaction between fiscal and monetary policy.

As a result, the institution delivering the most visible economic pain became the focal point of public frustration, even though inflation was being shaped by a much broader combination of fiscal decisions, monetary policy and external economic forces.

The Accountability Gap

These episodes reveal an asymmetry at the heart of Australia’s policy framework.

Governments receive political credit for:

• Tax cuts;
• Rebates;
• Infrastructure projects;
• Cost-of-living support.

The benefits are visible and easy to communicate.

The RBA, by contrast, often bears political responsibility for:

• Higher mortgage repayments;
• Slower economic activity;
• Reduced borrowing capacity;
• Falling asset prices.

The costs are immediate and highly visible to households.

This creates a situation where one institution frequently delivers the benefits while another delivers the pain.

That does not mean governments deliberately use the RBA as a scapegoat.

A more evidence-based conclusion is that the design of Australia’s institutions may create an accountability gap. The public naturally focuses on the decision-maker most visibly affecting household finances, even when the underlying economic outcomes result from a broader mix of fiscal and monetary policies.

Conclusion

Public debate often frames economic management as a story about the Reserve Bank.

But inflation is not created by the RBA, nor can it be controlled by the RBA alone.

Economic outcomes emerge from the combined effects of government budgets, taxation, spending decisions, monetary policy and global economic forces.

The experiences of 2007 and 2022-24 illustrate that fiscal and monetary policy do not always move in the same direction. When they do not, public attention tends to focus on the institution that raises interest rates because its actions are immediate and painful.

Perhaps the more important question is not whether the RBA receives too much scrutiny.

It is whether elected governments receive enough.

If you hold a mortgage, it probably feels like the Reserve Bank of Australia has a personal grudge against you. Every time they increase the cash rate, your disposable income takes a direct hit. And it is entirely reasonable to feel like they are targeting you to solve a national problem.

But the cash rate isn’t like a laser pointer aimed at your home loan. It is more like the thermostat to an air conditioner in a massive Australia sized house. And right now, the Australian economy is overheating.

Think of the entire country as a giant house. Over the last few years, everyone was moving around, working hard, and we all generated a lot of heat. Businesses were hiring frantically, global supply chains changed, and consumer spending surged. The economic temperature skyrocketed, and that blazing heat is what we call inflation. It devalues your savings, drives up the cost of groceries, and makes everything unlivable.

To fix this, the RBA has to turn on the air conditioner to cool the house back down to a comfortable 2% to 3% target zone.

The catch? The RBA only has one thermostat dial, the cash rate, and the vents to that air conditioner aren’t evenly distributed. Mortgage holders happen to be sitting directly underneath the main vent. You are feeling the icy blast first, and it freezes your budget.
But while you are shivering under that vent, the cold air is quietly moving through the rest of the house. Higher rates mean commercial banks stop handing out cheap money, businesses put massive expansion plans on ice, and savers suddenly lock their cash away in high-yield accounts rather than spending it. The thermostat is adjusting the climate for everyone. Mortgage holders just happen to be on the front line of the breeze.

How the Chill Spreads Beyond the Living Room

When you are sitting directly under the vent, it is easy to assume everyone else is enjoying a warm, comfortable room. But a thermostat change alters the climate of the entire house. The RBA’s cash rate sets the baseline price of money for the whole financial system, and as that price goes up, behavior changes in three distinct zones:

1. The Business Expansion Freeze

Just like a household budget, businesses rely on credit to grow. When the RBA raises the dial, commercial loans instantly become more expensive.

• The Reaction: That local manufacturing plant or tech startup that was planning to borrow $5 million to build a new warehouse or hire twenty new staff suddenly looks at the interest bill and says, “Not this year.”
• The Economic Impact: By forcing businesses to pause expansion, the RBA slows down hiring and reduces overall demand for raw materials and equipment. The corporate world catches a major chill.

2. The Incentive to Hoard Cash (The Savers’ Room)

For years, leaving money in a bank account felt like putting it under a mattress; you earned next to nothing. High interest rates completely flip that script.

• The Reaction: Suddenly, high-interest savings accounts and term deposits are offering 5% or more. If an investor or a wealthy household has $100,000 sitting around, they are no longer incentivized to risk it in the stock market or spend it on a new luxury car. They lock it away to collect guaranteed returns.
• The Economic Impact: This effectively vacuums active money right out of the economy. Instead of that cash circulating through retail stores, restaurants, and tourism, it sits frozen in a vault.

3. The International Currency Shield

We live in a global economy, and money flows wherever it can get the best return.

• The Reaction: When Australia’s interest rates rise relative to other countries, global investors want to move their capital into Australian banks to chase those higher yields. To do that, they have to buy Australian Dollars (AUD).
• The Economic Impact: This drives up the value of the AUD. A stronger dollar makes our imports, like cars, computers, and pharmaceuticals cheaper. It acts as an external shield, cooling down the global inflation we accidentally import at the docks.

The Global Currency Neighbourhood (The Mundell-Fleming Reality)

We like to think of our economy as an independent island, but financially, Australia is more like one house in a massive global street. And in that street, there is an invisible, unstoppable current called the Global Baseline Interest Rate.

This baseline is primarily controlled by the world’s financial heavyweights like the US Federal Reserve. Because the global economy is deeply interconnected and capital flows freely across borders, big global investors are constantly looking for the safest, highest-paying place to park their billions.

Here is how that reality forces the RBA’s hand:

• The Reality of Being a ‘Small Open Economy’: Australia is too small to dictate terms to global financial markets. If major central banks overseas raise their rates to say, 5%, and the RBA tries to keep Australian rates low at 3% to protect local mortgage holders, a massive chain reaction occurs.
• The Flight of Capital: Global investors, and even Australian super funds, will instantly pull their money out of Australian banks and move it overseas to chase those higher, safer returns.
• The Exchange Rate Collapse: To move that money out of the country, investors have to sell their Australian Dollars (AUD) and buy foreign currency. When everyone dumps the AUD, its value plummets.

Why a Crashing Currency Makes Life Worse

If the RBA lets the AUD crash just to save mortgage holders some pain, it triggers a different, more vicious kind of penalty for the whole country:

• Imported Inflation: Australia relies heavily on imports for everything from fuel and electronics to heavy machinery and cars. A weak currency makes everything we buy from overseas instantly more expensive.
• The Result: The price of petrol at your local bowser spikes, retail prices jump, and business costs skyrocket. The “heat” in our house goes up anyway, completely defeating the purpose of trying to keep rates low.

By lifting the local cash rate in lockstep with global trends, the RBA isn’t trying to be cruel. They are closing the front door of the house, to prevent the heat from the other houses coming inside, shielding the entire population from imported inflation.

The Hard Truth: Why We Can’t Just Turn Off the AC

It is completely valid to look at this entire system and feel a sense of deep frustration. If you have a mortgage, you are effectively being forced to sit directly under the freezing draft of the economic air conditioner, so the rest of the house doesn’t burn down. It feels unfair because the burden is inherently unequal.

But the alternative to this temporary chill is a permanent fire.

If the RBA chose to turn off the AC entirely by slashing interest rates to relieve mortgage holders while the economy was still running hot, then the consequences would ripple out to destroy everyone’s purchasing power equally.

When inflation gets locked into an economy, it changes from a temporary spike into a psychological trap:

• The Wage-Price Spiral: Workers demand higher pay to keep up with skyrocketing grocery bills. Businesses then raise prices to cover those higher wages. Around and around it goes.
• The Death of Savings: The money you worked hard to save quietly evaporates in value year after year.
• Economic Paralysis: When prices change by the week, businesses stop investing because they can’t predict their costs, and long-term economic growth grinds to a halt.

High interest rates are a painful, blunt, and deeply imperfect tool. They demand a heavy sacrifice from a single third of the country, the mortgage holders. But they are used because runaway inflation is a tax on 100% of the country, hitting the most vulnerable and those without assets the hardest.

The RBA isn’t adjusting the thermostat because they enjoy watching mortgage holders’ shiver. They are doing it because keeping the entire house from overheating is the only way to ensure we all still have a house to live in tomorrow.
