The 101 explainer

Build a clear, foundational understanding before going anywhere near a setup.

What the cash rate is, in plain English

The cash rate is the interest rate that commercial banks charge each other for overnight, unsecured loans. The cash rate target is the level a central bank officially sets to steer that market.

In Australia, the RBA sets the cash rate target to manage inflation and employment. While the names vary, each acts as an anchor for the following equivalents:

• United States: Federal Funds Rate
• United Kingdom: Bank Rate
• Eurozone: Main Refinancing Rate
• New Zealand: Official Cash Rate

A simple way to think about it is as the wholesale price of money. When that wholesale price rises, the retail prices linked to it, such as mortgage rates, business loans, savings rates and bond yields, often move higher too. When it falls, borrowing costs across the economy tend to ease.

For traders, this is the macro anchor. It is not just a number on an economic calendar; it influences currencies, indices, commodities, and yield-sensitive stocks.

Why the cash rate matters more than new traders expect

Central bank decisions are among the most closely watched events on the market calendar. That is because one rate decision can influence several markets at once, from currencies and bond yields to share indices, commodities and the cost of holding leveraged positions overnight.

It affects more than currencies

For CFD traders, this matters for two main reasons. First, leverage can magnify both gains and losses when markets are volatile. Around a central bank decision, price can move quickly, spreads can widen and risk controls become especially important.

It can change holding costs

Second, the swap or holding cost on a CFD position is linked to the underlying cash rate. When rates change, the cost of carrying a position overnight may also change. For example, a pair like AUD/JPY can behave differently when the yield gap between Australia and Japan is wide compared with when it is narrow.

Markets can reprice quickly

New traders often underestimate how fast markets can react. A central bank can shift expectations with one sentence in a statement or press conference.

Markets do not wait for the next quarterly review. They often adjust as soon as the message changes.

The key terms to know

You do not need to memorise every term in this list. These are the ones that come up most often around cash rate decisions.

What a 25 bps move may cost you

Basis points can sound abstract until you connect them to position size. Here is a simplified way to show why a small percentage move can matter for a CFD trader. A standard one-lot position in major FX is 100,000 units of the base currency and a 25 bps shift in the underlying cash rate is 0.25% per year.

The point is not the exact cents. It is that small-sounding percentage changes can compound on leveraged positions held for weeks or months.

How it works in real market conditions

A central bank decision is rarely just about the rate change itself. The market reaction is shaped by three layers: the decision, the statement, and any press conference or projections.

On 5 May 2026, the RBA raised the cash rate to 4.35%. While the hike was the headline, the statement and subsequent press conference provided the context that allowed markets to reprice bond yields and currency pairs in real time.

How central banks ripple across assets

Cash rate decisions rarely affect one market in isolation. They trigger a domino effect through currencies, yields, and volatility at varying speeds.

This kind of sector dispersion is not just an equities story. The same monetary tightening can produce sharply different outcomes across consumer segments, business sizes and parts of the wider economy, a dynamic sometimes called a K-shaped economy.

What many new traders miss

Markets react to the gap between expectations and reality. A hike that is fully priced in can lead to a falling currency; a hold with hawkish guidance can trigger a rally. The chart is only one part of the story. The setup may look simple, but the risk rarely is.

"Success in these events comes from understanding what is already priced in, and what would change the view if it does not play out that way."
