What is the RBA?

The RBA (Reserve Bank of Australia) is Australia's central bank. It sets monetary policy, issues banknotes, runs key parts of the payments system, and contributes to financial stability. If you've ever wondered why interest rates move, how inflation is managed, or where banknotes come from, the RBA's decisions and publications are the starting point. This guide explains what the RBA does, how decisions are made and published, and — most importantly — how those decisions filter through to your mortgage, savings and business borrowing.

Core functions

The RBA's responsibilities can be summarised into a few core roles:

• Monetary policy — Set the policy interest rate (the cash rate) to achieve the inflation target and support sustainable employment.
• Financial stability — Monitor and contribute to a stable financial system, working alongside regulators such as APRA and ASIC.
• Payments system — Operate and oversee key settlement systems (including real-time settlement) and support innovation in payment rails.
• Banknotes — Design, produce and issue banknotes and work to prevent counterfeiting.
• Banker to government — Provide banking services to the government and manage certain public debt operations.
• Research and data — Publish statistics, minutes, speeches and reports that help markets and the public interpret policy choices.

How monetary policy works

Monetary policy is the set of tools the RBA uses to meet its inflation target and support sustainable growth. The best-known tool is the cash rate — the rate at which banks lend to each other overnight.

Policy target: The RBA's framework aims to keep inflation near its target range while taking account of employment and broader economic conditions.

The cash rate: The RBA Board sets a target for the cash rate. That target influences short-term money market rates and, over time, bank lending and deposit rates.

Decision process: The RBA Board meets regularly (normally the first Tuesday of each month) to consider economic data, forecasts and risks. Decisions are made by the Board, which includes the Governor, Deputy Governor, the Treasury Secretary and independent members.

Publications and rhythm:

Board announcements with monetary policy decisions and a short statement are released immediately after the Board meeting. Minutes are published about two weeks after the decision and provide greater detail on the Board's discussions. The quarterly Statement on Monetary Policy provides in-depth analysis and the RBA's economic forecasts. Senior officials and staff publish speeches and papers that provide further context. Decisions are usually announced at set times (check the RBA calendar for exact release schedules at https://www.rba.gov.au/calendar/).

How the cash rate affects you

When the RBA changes the cash rate, the effect on your finances is indirect but generally quick:

Variable-rate mortgages: Lenders adjust their variable loan rates in response to cash-rate moves and market conditions. A 1 percentage point increase in the cash rate often translates into a similar — or slightly larger — increase in standard variable mortgage rates, depending on banks' funding costs and competition. For example, a 1 percentage point increase on a $100,000 mortgage raises annual interest by approximately $1,000 ($100,000 × 0.01 = $1,000).

Fixed-rate loans: Fixed rates are set by lenders based on expected future cash rates and the yield curve. They can move before or after a Board decision as markets price future policy.

Savings and deposit rates: Banks may increase deposit rates when the cash rate rises, but deposit-rate changes can lag and are influenced by competition for funds.

Business borrowing: Cash-rate changes influence short-term corporate lending costs, lines of credit and overdrafts. The effect on investment and hiring can be significant for small and medium businesses.

Credit cards and other consumer credit: While credit card rates don't move in lockstep with the cash rate, changes in market rates influence lenders' funding costs and the pricing of unsecured credit.

Exchange rates and inflation: Higher cash rates can support a stronger currency, lowering import prices and easing inflation; lower rates can reduce borrowing costs but may put upward pressure on inflation over time.

Transmission speed and magnitude vary by product and lender. Balance-sheet factors, funding markets and regulation all shape how quickly policy changes affect households and firms.

Other policy tools and balance-sheet operations

Beyond the cash rate, the RBA has other instruments it can use when markets are stressed or the cash-rate channel is insufficient:

• Short-term operations to add or remove liquidity (often repos) and overnight facilities that help set a corridor for short-term rates.
• Buying or selling government bonds to influence longer-term yields if necessary.
• Foreign-exchange operations in extreme or disorderly currency markets.
• Special programs in crisis periods to ensure credit keeps flowing to households and businesses.

These tools are best understood as backstops or complements to the cash rate rather than everyday policy levers.

Payments system and banknotes

The RBA runs the plumbing that keeps transactions moving:

Settlement systems: It operates Real-Time Gross Settlement (RTGS) and supports the New Payments Platform (NPP), ensuring obligations between banks are settled securely and promptly.

Oversight and cooperation: The RBA works with industry and regulators to promote efficiency, resilience and competition in payments.

Banknotes: The RBA issues polymer banknotes, manages design and security features, and publishes statistics on issuance and counterfeiting deterrence.

A resilient payments system reduces settlement risk and underpins confidence in everyday payments and large-value transfers.

Independence, accountability and governance

Independence and transparency are central to central-bank credibility:

Legal and governance framework: The RBA is a statutory body with responsibilities and governance arrangements described on the RBA's about pages. Its monetary policy decisions are operationally independent.

The Board: The Board sets monetary policy and is accountable through statutory reporting, public minutes and appearances before Parliament.

Relationship with other agencies: The RBA works closely with Treasury, APRA and ASIC — each has distinct responsibilities (fiscal policy, prudential regulation, market conduct).

Transparency: The Bank publishes minutes, the quarterly Statement on Monetary Policy, the Financial Stability Review and a full statistical database so the public and markets can assess its decisions.

Transparency — timely announcements, explanatory minutes and rich data — reduces uncertainty and helps households and businesses plan.
