The Reserve Bank of Australia, usually shortened to the RBA, is Australia’s central bank. It sets the country’s main interest rate, known as the cash rate, and its decisions ripple through mortgages, savings, the Australian dollar and even global markets. For traders in London, the RBA matters because it often meets during the Asian session, so its decisions set the tone before Europe opens.
What the RBA does
Like the Bank of England or the US Federal Reserve, the RBA’s main job is to keep inflation under control while supporting employment. Its target is to keep inflation between 2 and 3 per cent over time. When inflation runs too hot, the RBA raises the cash rate to make borrowing more expensive and cool spending. When the economy weakens, it cuts rates to encourage borrowing and investment.
The RBA also manages Australia’s foreign currency reserves, oversees the payments system and issues the country’s banknotes.
How decisions are made
Rate decisions are made by a monetary policy board that meets eight times a year. Decisions are announced at 2.30pm Sydney time, which falls in the early hours of the morning in the UK. Alongside the decision, the board releases a statement explaining its thinking and, in some meetings, updated economic forecasts. The governor then holds a press conference.
Traders pay close attention to how board members vote. A split decision, such as six members in favour and three against, tells the market the board is divided and that future moves are less certain. This week the RBA raised its cash rate to 4.85 per cent on a six to three vote, as covered in our Morning Market Brief.
Why the RBA moves the Australian dollar
Currencies respond to interest rate differences. If Australian rates rise relative to those in the US or UK, holding Australian dollars becomes more rewarding, which can support the currency. But the reaction depends on expectations. If a hike is fully expected, the Australian dollar may barely move, or even fall if the RBA signals it is close to finished.

Why the RBA matters beyond Australia
Australia is a major exporter of iron ore, coal and gas, and China is its biggest customer. That means the RBA’s view of the economy often contains useful clues about Chinese demand and global commodity prices. Its decisions can also influence other central banks in the region, and its commentary on inflation from energy prices is relevant to the UK too.
What traders watch on decision day
- The decision versus expectations. Did the RBA do what markets had priced in?
- The vote split. A narrow majority suggests a less predictable path.
- The statement’s tone. Words about inflation risks or slowing growth hint at the next move.
- The forecasts. When the RBA expects inflation to return to target shows how long rates may stay high.
- The Australian dollar and local bond yields. These give the instant verdict.
A beginner’s takeaway
You do not need to trade the Australian dollar to benefit from following the RBA. Its decisions offer a window into global inflation, commodity demand and the direction of interest rates around the world. Treat decision day as a lesson in how central banks communicate and how markets react to surprises.
