The Reserve Bank of Australia (RBA) is Australia’s central bank and the key institution responsible for setting and implementing monetary policy to keep inflation low and stable, support full employment and promote the economic prosperity and welfare of the Australian people.
Its main instrument is the cash rate target—the interest rate on overnight loans between banks—which the RBA adjusts to influence other interest rates, spending, and inflation across the economy.
RBA mandate and objectives in monetary policy
The RBA’s role and objectives are set out in the Reserve Bank Act 1959, which charges it with:
- Stability of the currency of Australia
- Maintenance of full employment
- Economic prosperity and welfare of the people of Australia
Investopedia’s overview “Reserve Bank of Australia: Role, History, and Monetary Policy” explains that the Bank pursues these objectives mainly through monetary policy and by managing the payments system and issuing banknotes. In practice, the RBA and the Australian Government operate under an inflation target of 2–3% on average over time, agreeing that this level of inflation is consistent with currency stability and sustainable growth.
The article “RBA Monetary Policy: Managing the Australian Economy” summarises the RBA’s aim as keeping inflation within the 2–3% band while supporting employment and economic activity, using adjustments in the cash rate and clear communication to guide expectations.
A teaching note on the roles and functions of the Reserve Bank of Australia emphasises that while the Bank also promotes financial‑system stability, issues currency and provides banking services to government, its central macroeconomic responsibility is monetary policy.
How the RBA sets monetary policy: the Monetary Policy Board and the cash rate
Monetary policy decisions are made by the Monetary Policy Board (formerly the Reserve Bank Board), which meets 11 times per year, usually on the first Tuesday of each month except January.
According to Investopedia’s RBA profile, the Board reviews data on inflation, employment, GDP, wages, global conditions and financial markets, then decides whether to raise, lower or hold the cash rate target. After each meeting, the RBA publishes a media release outlining its decision and reasoning.
In its 2 February 2026 media release, “Statement by the Monetary Policy Board – Monetary Policy Decision,” the RBA announced it had increased the cash rate target by 25 basis points to 3.85%, while the interest rate paid on Exchange Settlement (ES) balances was also adjusted higher. The Board explained that although inflation had fallen from its 2022 peak, it had picked up in late 2025 and was likely to remain above the 2–3% target without more restrictive policy.
The cash rate target and the policy interest‑rate corridor
What is the cash rate?
The cash rate is the interest rate on unsecured overnight loans between banks in the Australian money market. The RBA’s explainer “How the Reserve Bank Implements Monetary Policy” describes the cash rate target as the main lever of monetary policy in Australia. By changing the cash rate target, the Bank influences other interest rates:
- Variable home‑loan rates
- Business loan and overdraft rates
- Deposit and savings rates
These changes affect household and business spending, asset prices, the exchange rate and ultimately inflation and employment.
The policy interest‑rate corridor
To keep the actual cash rate close to the target, the RBA operates a policy interest‑rate corridor.
The RBA’s explainer and its teacher update “Bridging the Textbook Gaps on How the RBA Implements a Change in Monetary Policy” explain that the corridor is defined by:
- A ceiling – the rate at which the RBA will lend overnight to banks.
- A floor – the rate the RBA will pay on ES balances that banks hold at the central bank.
Banks will not normally borrow at rates above the RBA’s lending rate or lend at rates below the deposit rate, so all cash‑market transactions occur within this corridor. When the Board alters the cash rate target, the RBA shifts the corridor up or down and adjusts the rate it pays on ES balances, ensuring that banks trade at rates consistent with the new stance.
The RBA implementation explainer notes that in the current “ample reserves” environment, the cash rate tends to sit close to the floor of the corridor, with ES balances plentiful after years of bond purchases and liquidity support.
Implementation tools: open market operations and ES balances
To ensure the cash rate trades near its target, the RBA uses open market operations (OMOs) in short‑term money markets.
A BIS review, “The RBA’s Monetary Policy Implementation System”, explains that the Bank conducts repurchase agreements (repos) and outright transactions in government securities to adjust the supply of ES balances.
- By supplying more ES balances through repos, the RBA puts downward pressure on the cash rate.
- By draining reserves (or supplying less), it pushes the cash rate up toward the corridor ceiling.
The RBA’s implementation explainer states that OMOs are used to ensure that the quantity of ES balances is consistent with the cash rate trading close to target, while the corridor’s floor and ceiling anchor the possible range of rates.
For students, the “RBA Monetary Policy: A Year 12 Economics Guide” clarifies that:
- The RBA allows the cash rate to fluctuate in a narrow band of about 5–10 basis points around the target.
- It offers term repos (e.g., 7‑day, 28‑day) via regular operations, meeting banks’ liquidity needs at rates aligned with the policy stance.
During the COVID‑19 crisis, the RBA went beyond conventional OMOs. A paper in the Journal of Economic Literature, “The Reserve Bank of Australia’s policy actions and balance sheet,” explains that the Bank introduced a Term Funding Facility, implemented yield‑curve control on 3‑year government bonds and purchased large volumes of bonds to compress longer‑term rates and support credit. These measures significantly increased ES balances and shifted the implementation environment toward very ample reserves.
Transmission of monetary policy: from cash rate to the real economy
The RBA’s explainer “The Transmission of Monetary Policy” describes how changes in the cash rate flow through to the broader economy via several channels.
- Interest‑rate channel: A higher cash rate raises variable mortgage, credit‑card and business‑loan rates, increasing repayments and discouraging borrowing and spending; a lower cash rate does the opposite.
- Exchange‑rate channel: Higher interest rates tend to appreciate the Australian dollar by attracting foreign capital, which can reduce export competitiveness but lower the cost of imports; lower rates usually weaken the currency and support exports.
- Asset‑price and wealth channel: Rate changes can influence equity and housing prices; rising rates may cool asset markets and dampen wealth, while falling rates can support valuations and confidence.
- Expectations channel: Through its statements and forecasts, the RBA shapes expectations for future inflation and interest rates, influencing wage bargaining, price setting and investment decisions.
Over time, tightening policy (raising the cash rate) tends to reduce demand and bring inflation down, while easing policy (cutting the cash rate) supports demand, employment and inflation when it is below target.
Recent RBA monetary policy decisions (2025–2026)
After raising rates sharply in 2022–2023 to tackle high inflation, the RBA began cautiously easing in 2025 as inflation moderated, then tightened again in early 2026 when price pressures re‑emerged.
2025: From restrictive to slightly less tight
A February 2025 note, “RBA Monetary Policy Decision Summary – February 2025”, reports that the Board cut the cash rate to 4.10%, setting the rate on ES balances at 4.0%. The summary states that:
- Underlying inflation had fallen to 3.2% in the December quarter.
- Private demand remained subdued, with weak consumption and construction.
- Wage growth had eased, reducing risks of a wage‑price spiral.
The Board judged that monetary policy remained restrictive but could be eased slightly to avoid unnecessarily slowing the economy, while still guiding inflation back to target.
By December 2025, Money Management’s article “RBA makes final 2025 rate decision” notes that the Bank held the cash rate at 3.6%, the third straight hold and fifth for the year, after reducing the rate in earlier months. The decision reflected concerns that while inflation was declining, it was still above target, and the labour market remained relatively tight.
2026: Re‑tightening as inflation picks up again
In its 2 February 2026 statement, the RBA raised the cash rate target by 25 basis points to 3.85%, with the ES balance rate lifted correspondingly. The RBA’s media release explains that:
- Inflation had fallen substantially from its peak but picked up again in the second half of 2025.
- Capacity pressures and stronger demand made it likely that inflation would remain above the 2–3% target without further tightening.
- Monetary policy therefore needed to be “sufficiently restrictive” to ensure inflation returned to target within a reasonable timeframe.
This sequence illustrates the RBA’s data‑dependent approach: adjusting the cash rate as new information emerges about inflation, growth and the labour market.
Common misconceptions about the RBA’s role
Public commentary often misunderstands what the RBA can (and cannot) achieve.
UNSW BusinessThink’s article “The RBA explained: what we get wrong about the Reserve Bank” highlights several misconceptions:
- The RBA does not control all interest rates; it directly targets only the overnight cash rate and influences others indirectly—market forces, competition and risk premiums still matter.
- Monetary policy can slow or stimulate the economy and influence inflation, but it cannot directly fix structural issues such as housing supply shortages or productivity trends.
- The Bank must manage trade‑offs; it cannot simultaneously guarantee low inflation, very low unemployment and zero volatility in growth.
A teaching Q&A, “Explain what monetary policy is, how it is implemented in Australia by the Reserve Bank”, similarly stresses that monetary policy is about adjusting interest rates and liquidity to achieve the inflation target over the medium term, not micromanaging individual prices or markets.
Why the RBA’s monetary policy matters for households and businesses
RBA decisions affect borrowing costs, savings returns and economic conditions, so they matter directly for households and businesses.
The Alphafinance explainer on RBA monetary policy notes that when the cash rate rises, variable mortgage and business‑loan rates usually go up, increasing repayments and reducing disposable income, while deposit rates rise and benefit savers. When the cash rate falls, borrowing becomes cheaper and can stimulate housing demand, consumer spending and business investment.
The 2020 paper “The Reserve Bank of Australia’s policy actions and balance sheet” shows how, during COVID‑19, the RBA used low rates and special funding facilities to keep credit flowing and borrowing costs low, helping businesses survive the downturn and supporting the recovery.
The RBA’s transmission explainer emphasises that by anchoring inflation expectations and providing predictable policy, the Bank helps households and firms make long‑term financial decisions.
