RBA Explained

The Reserve Bank of Australia (RBA) is Australia’s central bank. Its role is to issue Australian currency and set our country’s monetary policy. The RBA is tasked with ensuring the stability of the Australian financial system and aims to look after both the economic prosperity and the welfare of all Australians.

The RBA is wholly owned by the Commonwealth of Australia. The bank’s board consists of up to nine members who are appointed by the Treasurer, and the current Chair of the RBA board is Glenn Stevens.

What is the official cash rate and who sets it?

One of the key responsibilities of the RBA is setting the official cash rate. This is the rate the RBA offers on overnight loans to commercial banks, and changes to the rate have widespread repercussions for the economy as a whole.

Once a month, the RBA board meets to decide whether to raise the cash rate, lower it or keep it the same. Their decision will be influenced by a wide range of factors including inflation, the performance of the Aussie Dollar, the housing market, Australia’s Gross Domestic Product (GDP) and levels of consumer confidence. The board will assess all of these factors in relation to the RBA’s goals and objectives before reaching a consensus on what to do with the official cash rate.

A look at the RBA's historic cash rate moves

If the RBA wants to encourage Australians to spend money and stimulate growth in the economy, they may look at lowering the cash rate. If they want to cool down an overheating economy, raising the rate can help control consumer spending levels across the country.

How does the cash rate affect home loan interest rates?

Banks and other lenders all over the country use the RBA’s official cash rate as the benchmark for the rates they offer on their variable rate home loans and other financial products. You may have seen or heard news stories following a rate change announcement by the RBA as economists predict when the banks will pass the RBA’s change on to their customers.

For people with home loans, rising interest rates can spell future financial pain. A higher variable rate means you’ll have to pay more interest on the money you have borrowed. If the cash rate is dropped, however, this can lead to banks lowering their interest rates, and in turn lead to lower repayments for borrowers.

The story is a little different for those people who are locked into fixed rate loans. While these borrowers are protected against any rate rises, they can’t take advantage of any rate decreases when they occur.

What does the RBA have to do with inflation?

The RBA’s monetary policy aims to achieve three key objectives which are set out in the Reserve Bank Act 1959:

  • The stability of the currency of Australia;
  • The maintenance of full employment in Australia; and
  • The economic prosperity and welfare of the people of Australia.

In order to reach those objectives, the RBA sets an inflation target of 2-3% over the medium term. In other words, the RBA wants the Consumer Price Index (CPI, based on the average prices for a range of common goods and services) to increase by between 2 and 3 per cent each year.

The bank can control inflation by making adjustments to the official cash rate. For example, if inflation rises above the target rate it means that Australians are spending their money too freely and prices are increasing too rapidly. But if the RBA raises interest rates to make it more expensive to borrow money, the economy will settle and price increases will slow down. Conversely, the RBA will drop interest rates if inflation is too low and the economy is stagnating, encouraging more Australians to spend more money and stimulate economic growth.

    Hi Colin,

    Thanks for your question.

    Savings accounts interest rates generally move in line with the RBA cash rate. If you see the RBA cash rate decrease, savings accounts rates generally go down as well.

    Cheers,
    Shirley
