What it means
The Reserve Bank of Australia, often shortened to the RBA, was established under legislation passed in 1959 and began operating as the central bank in 1960. It is owned by the government but is expected to make its monetary policy decisions independently.
Its main tool is the cash rate target, which is the interest rate on overnight loans between banks. When the RBA raises or lowers that target, other rates, including those on mortgages, business loans and savings, usually follow.
The bank's policy aims include stable prices, which in practice means keeping inflation within a target range agreed with the government, and supporting full employment and the economic welfare of Australians. It publishes its decisions after scheduled board meetings and explains them in statements.
The RBA has other roles as well. It issues banknotes, acts as banker to the government, manages the country's official reserves, oversees the payments system and works with other regulators to promote financial stability.
For businesses, the RBA matters because borrowing costs, exchange rates and consumer demand all respond to its decisions. A finance team with floating-rate debt will want to model how a change in the cash rate affects interest costs, while an exporter will watch the effect on the Australian dollar.
Non-Australian companies matter too. Multinationals with Australian subsidiaries need to understand RBA policy in order to forecast local costs, and investors compare Australian rates with those elsewhere when they decide where to place money.
In practice
Real-world examples.
Example
A property developer in Sydney has a construction loan of A$30,000,000 priced off a benchmark linked to the cash rate. After the RBA cuts its target, the developer's interest bill falls, and its finance team updates its cash flow forecast and tells the lenders about the improved interest cover.
Example
An Australian wine exporter watches the RBA's decisions closely. When the bank signals higher rates, the Australian dollar tends to strengthen, which lowers the exporter's local currency receipts from overseas sales. Its treasurer therefore reviews the forward contracts that lock in exchange rates for the next two harvests.
Example
A retail chain uses the RBA's published inflation outlook when setting next year's wage increases and price changes. The finance director builds the budget on a central case and a higher inflation case, so the board sees the range and understands how much margin protection is needed.
Formula
Calculation
Change in annual interest cost = loan balance x change in interest rate.
Suppose an Australian company has a floating-rate loan of A$4,000,000, and the cash rate rise passes through to the loan in full at 0.25 percentage points (0.0025). The extra interest each year = 4,000,000 x 0.0025 = A$10,000. If the RBA raises rates by 0.25 percentage points three times in a row, the cumulative rise is 0.75 percentage points, so the extra interest each year = 4,000,000 x 0.0075 = A$30,000.Case study
Seen in the real world.
Southern Cross Hardware is an illustrative, fictional building supplies company with stores across Australia. It borrowed A$20,000,000 at a floating rate to fund new warehouses and had never modelled how rate changes would affect its profit.
When the central bank began a series of rate rises, the finance director built a sensitivity table. Each 1 percentage point rise would add A$200,000 a year to interest costs, and the company's profit before interest and tax of A$3,000,000 gave it room to absorb a rise but not an unlimited number of rises.
She arranged to fix half the debt for three years, which cut the exposure to A$100,000 for each percentage point. The illustrative lesson is that the central bank's decisions are a regular budgeting input, not just a news headline, and she now reports the sensitivity to the board after every policy meeting.
Watch out
Common mistakes.
- Assuming the RBA directly sets the rate on every loan, when it sets the cash rate and commercial banks decide how much of a change to pass on.
- Forgetting that the effect of a rate change reaches different businesses at different times, depending on whether their debt is floating or fixed.
- Treating the RBA as a government department that follows political instructions, when its monetary policy decisions are made independently.
Questions
People also ask.
What is the cash rate?
It is the interest rate on unsecured overnight loans between banks, which the RBA targets and which influences interest rates across the economy.
How often does the RBA decide on interest rates?
It holds scheduled policy meetings through the year and publishes its decisions and reasons soon after each one.
Does the RBA regulate banks?
Banks are supervised mainly by a separate prudential regulator, though the RBA works with it on financial stability and oversees the payments system, so its work still touches the safety of the banking sector.
