RBA Interest Rate Rises and Fairer Inflation Control

Another interest rate rise means another household budget under pressure. Mortgage holders must find more money for the bank. Businesses face dearer finance. Workers worry about reduced hours, while people already struggling with food and rent have little spending left to cut.

RBA interest rate rises can help reduce inflation. The question is whether Australia relies too heavily on them when governments have other powers that could address rising prices and share the costs more fairly.

The Reserve Bank of Australia knows those alternatives exist. Many, however, sit outside its authority. That makes inflation a responsibility for elected governments as well as the central bank.

Quick Answer

Australia relies on interest rates because the cash rate is the RBA’s main policy tool. Higher rates restrain spending, investment and inflation, but affect households unevenly and cannot directly fix shortages. Governments can use other tools, including taxes, public investment, competition rules, and support for essential costs. A better approach would match each policy to the cause of inflation, protect people with little room to cut spending, and expand supply where feasible. Some demand restraint may still be needed. The aim should be to reduce reliance on rate rises without promising that inflation can be controlled quickly or without difficult choices.

What the latest figures show

On 3 November 2026, the RBA increased the cash-rate target by 0.25 percentage points to 4.85 per cent. Its November Statement on Monetary Policy says higher fuel prices and wider domestic cost pressures are keeping inflation elevated. It expects inflation to return to the middle of its target range in mid-2028. This is a forecast, not a guarantee. [1]

The Australian Bureau of Statistics September release, published on 28 October, recorded annual consumer price inflation of 4.3 per cent. The trimmed mean, which reduces the influence of unusually large price movements, was 3.6 per cent. Housing prices in the consumer basket rose 5.2 per cent over the year. [2]

These figures explain why inflation remains a policy concern. They do not establish that another rate rise is the best available response, or that every household has been spending beyond its means.

Why the RBA keeps choosing interest rates

The July 2025 monetary policy agreement between the government and the RBA identifies the cash-rate target as the Bank’s primary instrument. It sets an inflation target of 2–3 per cent and requires the Bank to balance price stability and full employment. There is flexibility over the time taken to return inflation to target. [3]

The RBA has used other tools. These include government bond purchases, guidance about future policy and low-cost funding for banks. Much of that experience involved supporting activity when conventional interest rates were very low. Those tools do not give the RBA the powers of a government department or Parliament. [4]

The RBA cannot change income tax, commission a national public housing program or legislate supermarket rules. It can influence financial conditions across the economy. Governments can make more specific choices about spending, taxation and regulation.

That division explains the reliance on rates. It does not settle whether the chosen level is appropriate. The Board still makes judgements about forecasts, risks and how much pressure households and employment can bear.

How higher rates reduce inflation

Higher rates change the rewards for saving and the costs of borrowing. They can discourage purchases and investment, reduce asset values, and affect the exchange rate. A stronger Australian dollar, other things equal, makes imports cheaper. The RBA’s transmission explainer describes several channels and uncertainty about their timing. The Bank also examines these effects in its economic models. [4, 20]

The most visible effect is the squeeze on borrowers. But monetary policy works more broadly than mortgage repayments alone. Businesses may delay expansion because expected returns no longer justify financing costs. Weaker sales can reduce hiring.

As an illustration, an extra 0.25 percentage points on a $600,000 loan adds about $1,500 a year in interest at an unchanged balance. That is roughly $125 a month in interest alone. The change in a principal-and-interest repayment depends on the loan’s remaining term and starting rate. This is arithmetic, not a quoted bank repayment.

The purpose is to bring spending closer to what the economy can supply. When that happens, businesses have less scope to raise prices. The burden can still be severe for someone whose budget was already tight.

Who carries the burden

The RBA’s January 2025 household cash-flow study finds that borrowers’ spending is generally more sensitive to changes in available income than savers’ spending. Lower-income borrowers also tend to have smaller financial buffers. Higher rates reduce household cash flow in aggregate because interest-sensitive debt exceeds interest-sensitive assets. [5]

Some deposit holders receive more interest. That includes retirees of modest means as well as wealthy households. Meanwhile, a debt-free homeowner may still suffer from inflation, falling investment values or a family member losing work. Age alone is a poor guide to who benefits.

Mortgage stress is only part of the story. Small businesses must meet financing costs while customers cut spending. Employees can face fewer shifts or weaker hiring. Our article on the human cost of unemployment examines those consequences. [6]

There is also a measurement issue. Mortgage interest is excluded from the Consumer Price Index, but included in the ABS Selected Living Cost Indexes. Those measures serve different purposes. A household can therefore experience rising mortgage costs while the inflation measure targeted by the RBA improves. The ABS explanation of housing costs makes this distinction clear. [7]

Different causes need different responses

Inflation can arise when spending exceeds available capacity. It can also follow fuel disruptions, poor harvests or shortages of essential inputs. Often these forces overlap.

In a July 2026 speech on supply shocks, RBA Assistant Governor Sarah Hunter explained that monetary policy manages demand and cannot materially change the economy’s long-term productive capacity. Supply shocks can lift inflation while weakening activity, creating a difficult trade-off. [8]

An interest rate rise cannot restore an oil shipment or train an electrician. Yet persistent supply-driven inflation can spread into other prices and expectations. The Bank may still judge that restraining demand is necessary to stop inflation becoming entrenched.

The useful policy question is how much demand must fall, how quickly supply can improve, and who should bear the adjustment. A household buying necessities has far less room to respond than one making large discretionary purchases.

Better options alongside RBA interest rate rises

Use fiscal policy to share necessary restraint

Fiscal policy means government decisions about taxes and spending. It can reduce total demand while protecting essential services and assistance for people in hardship.

The International Monetary Fund’s 2023 analysis found that fiscal restraint can support inflation control and reduce the monetary tightening required. Its modelling also examined protecting vulnerable households through targeted transfers. This supports a broader policy mix; it does not provide an exact prescription for Australia today. [9]

My view is that governments should examine poorly justified concessions and lower-priority spending before cutting services relied on by people with low incomes. Where further restraint is needed, progressive taxation deserves consideration.

Fairness and inflation control still need separate tests. A tax on very high incomes may be equitable, but affluent households might reduce saving rather than spending. A windfall-profits tax does not automatically lower shelf prices. Governments should estimate the effect on demand, investment and prices instead of assuming that a large revenue figure guarantees a large inflation reduction.

Build housing capacity with a realistic delivery plan

Higher borrowing costs can slow the construction needed to ease housing shortages. The RBA acknowledges this effect in its analysis of housing market fundamentals. Planning, infrastructure, land and building costs also influence whether projects proceed. [10]

A sustained public and community housing program could provide homes outside the private market and reduce unmet need. Its value depends on completed, suitable dwellings, rather than funding announcements alone.

Delivery requires serviced land, tradespeople, materials and capable project management. The Productivity Commission’s housing construction research identifies slow approvals, limited innovation and workforce issues among barriers to better performance. [11]

My recommendation is to link housing commitments to workforce training and a staged construction schedule. Governments should coordinate competing infrastructure projects so they do not all bid for the same workers at once. Public investment can ease future scarcity while adding to demand during construction; both effects belong in the plan.

Reduce energy costs through reliable supply and efficiency

Energy affects household bills and the cost of producing and transporting goods. Measures that improve supply and reduce energy waste can address costs more directly than a mortgage increase.

The Australian Energy Market Operator’s 2026 Integrated System Plan identifies renewables, networks, storage and gas backup as the least-cost pathway for the National Electricity Market through to 2050 as coal plants retire, while meeting government policies. It is a system plan under stated assumptions, rather than a promise of immediate retail bill reductions. [12]

Governments can help deliver infrastructure and household efficiency upgrades, including access for renters and low-income households. Projects need cost controls and reliable delivery. Electricity bills also include network, retail and other costs, so cheaper generation alone cannot determine the final price.

Temporary bill relief can protect households now. Its success should be judged separately from investment that changes the underlying cost of supplying energy.

Strengthen competition and enforce existing rules

The Australian Competition and Consumer Commission (ACCC) supermarket inquiry reported in March 2025 that average product margins at ALDI, Coles and Woolworths had increased over the preceding five financial years. It recommended clearer pricing, better supplier transparency and changes to planning and zoning to support competition. [13]

There has also been legislative action. The ACCC states that an excessive-pricing prohibition for very large supermarket retailers commenced on 1 July 2026. That is an existing measure requiring enforcement and evaluation, rather than a reform still awaiting commencement. [14]

Governments should report whether these measures improve prices, entry and supplier treatment. The inquiry provides grounds to challenge market power. It does not establish that supermarket profits explain all Australian inflation.

Price regulation can also be considered where essential markets are failing. Its design matters: limits that leave suppliers unable to cover efficient costs can discourage supply. Any intervention should identify the problem, monitor availability and quality, and provide for review.

Protect essentials while managing total demand

People need food, healthcare, transport and somewhere to live. Protecting access to those essentials should be an explicit part of inflation policy.

Targeted assistance can prevent hardship, but it still adds spending power. Its inflation effect depends on its size, how it is financed and whether supply can respond. A broad payment to households with comfortable buffers serves a different purpose from assistance that prevents someone going without medicine.

Rebates also need clear accounting. Lowering the bill a consumer pays can reduce measured inflation temporarily. It does not necessarily lower the underlying cost, and withdrawing the rebate can lift the measured price later. Governments should explain immediate relief and lasting cost reductions separately.

Use lending safeguards for the job they can do

Bank lending rules can address risky credit growth more precisely than raising borrowing costs for everyone. But they have a different primary purpose.

The Australian Prudential Regulation Authority’s framework focuses on financial stability. Measures affecting lending standards can limit the build-up of dangerous debt; they do not directly solve food or fuel inflation. Tight restrictions can also make access harder for some prospective buyers. [15]

Lending safeguards can complement a wider strategy. They should not be advertised as a complete replacement for monetary policy.

What monetary sovereignty changes

Australia issues its own currency and has a floating exchange rate. The Commonwealth’s position therefore differs from a household’s or a state government’s. The RBA’s exchange-rate explainer describes the floating currency system, while the Australian Office of Financial Management explains how it issues government securities and manages Commonwealth financing. [16, 17]

Under current arrangements, expenditure still requires legal authority and cash management. Monetary sovereignty does not mean ministers can bypass Parliament or ignore financing arrangements. Our explanation of taxes and government spending explores that distinction. [18]

The practical implication is to assess public investment against available resources and public benefit, rather than treat the federal budget as a family savings account. Dollars cannot create skilled workers overnight, make imported equipment available or remove environmental limits.

A weaker Australian dollar can also raise import costs. Sovereignty gives Australia policy choices; it cannot guarantee favourable overseas prices or exchange rates.

Make governments and the RBA explain the whole strategy

An effective division of responsibilities needs public accountability. RBA independence should coexist with scrutiny of its forecasts and decisions. Governments should explain their own contribution to price stability.

I propose a regular public inflation plan setting out:

Which price pressures appear temporary and which are persistent.

Where excess demand, supply shortages or weak competition matter most.

Which institution is acting, what it expects to achieve and when.

How the measures affect borrowers, renters, workers and people on low incomes.

What evidence would trigger a change of approach.

This would make alternatives concrete. A government proposing housing investment would need to show its delivery capacity. One proposing spending cuts would need to explain the services affected and the expected price benefit. The RBA would need to explain why its chosen level of restraint fits the evolving evidence.

A fairer approach is possible

Inflation harms ordinary Australians, especially those with little room in their budgets. It needs a serious response. Interest rates can contribute, but their broad reach creates costs that deserve more attention.

My conclusion is that Australia should reduce its dependence on rate rises through a deliberate mix of targeted restraint, essential-service protection, supply investment and effective market oversight. That approach cannot promise an immediate rate cut. It can make inflation policy more accountable and give governments responsibility for the choices only they can make.

The test should be whether prices become more stable while people retain access to secure housing, decent work and essential services.

Frequently Asked Questions

Could the RBA simply use taxes instead

No. Tax changes are decisions for governments and parliaments. The RBA sets monetary policy. Governments can use fiscal policy alongside it to influence demand and distribution. [3, 9]

Would cutting interest rates make inflation worse

It could, by encouraging spending and investment or weakening the dollar. The effect depends on economic conditions. Identifying the costs of high rates does not establish that an immediate cut is safe. [20]

Do landlords automatically pass mortgage increases to renters

No. RBA research published in October 2024 found small direct pass-through on average using earlier tax data. Local supply and demand remain central. The study does not settle every experience in today’s rental market. [19]

Does lower inflation mean prices return to previous levels

Usually it means prices rise more slowly. Broadly falling prices are called deflation. Some individual prices can fall even while the overall consumer basket becomes more expensive.

Can public investment help while inflation is high

Yes, if well designed and sequenced. Investment can expand supply, but construction also uses workers and materials immediately. Timing, capacity and any offsetting demand measures are crucial. [8, 11]
