Core Responsibilities of the RBA
1. Monetary Policy and the Cash Rate
The most widely recognised function of theRBA is the setting of the cash rate. This is the interest rate charged onovernight loans between financial institutions. It serves as a benchmark forother interest rates, including those on mortgages, business loans, and savingsaccounts.
The RBA adjusts the cash rate to eitherstimulate or cool the economy. If inflation is too high or consumer spending issurging, the RBA may raise the cash rate to rein in demand. Conversely, wheneconomic activity slows, a lower cash rate can encourage borrowing andinvestment.
Every month (excluding January), the RBABoard meets to assess economic conditions and determine whether a change in thecash rate is needed. These decisions have a direct effect on equity markets,currency values, and investor sentiment.
2. Maintaining Financial SystemStability
The RBA plays a crucial role in promotingfinancial stability by overseeing liquidity across the banking system andcoordinating with other key regulators such as the Australian PrudentialRegulation Authority (APRA) and the Australian Securities and InvestmentsCommission (ASIC).
During times of economic stress — such asthe COVID-19 pandemic — the RBA may intervene by injecting liquidity into thesystem, ensuring banks remain functional and credit continues to flow.
Stable financial systems attract investorconfidence, making it easier for markets to function efficiently. Investorsrely on the RBA’s oversight to ensure that the risk of systemic failure remainslow.
3. Issuing Banknotes and OverseeingPayments
The RBA is the sole issuer of Australia’sphysical currency. It also oversees and operates the core of the country’spayments infrastructure, which processes billions of dollars in transactionsdaily.
Its aim is to ensure that payments aresafe, efficient, and resilient. Recent innovations include support forreal-time payments through the New Payments Platform (NPP), allowing consumersand businesses to transfer funds instantly.
For investors and financial institutions, arobust payments system is essential for market efficiency, execution of trades,and day-to-day operations.
4. Managing Foreign Exchange Reserves
The RBA manages Australia’s foreigncurrency reserves, which can be used to stabilise the Australian dollar duringperiods of volatility. This role is especially important in times of globaluncertainty, when capital flight or currency shocks could threaten economicstability.
While the RBA does not target a specificexchange rate, it may intervene in currency markets if conditions warrant it —such as during a currency crisis or sudden speculative attack.
Currency fluctuations can affect Australianexporters, multinational companies, and global investors. A well-managedforeign reserve position acts as a financial buffer for the entire economy.
5. Governance, Transparency, andAccountability
The RBA is governed by a Board composed ofexperts, including the Governor, Deputy Governor, Treasury representatives, andindependent members appointed by the government.
It is accountable to the Australian Parliament and provides regular reports, including the quarterly Statementon Monetary Policy. Public speeches, press conferences, and meeting minutesalso ensure that the RBA maintains a high level of transparency.
Investor confidence is strongly linked tothe credibility of central banks. Inconsistent or opaque policies can shakemarkets, but the RBA’s structured communication strategy helps set expectationsand reduce unnecessary market shocks.
