Central Banks Explained: Fed, ECB, BoE, BoJ and What Traders Watch

The big four central banks set the tone for currencies. What each one does, when they meet and which phrases move markets.

What they do

Central banks aim for stable prices and, in some cases, full employment. Their main tool is the policy interest rate, plus balance-sheet measures such as bond buying (quantitative easing) or reduction (quantitative tightening).

The big four

The US Federal Reserve (Fed), the European Central Bank (ECB), the Bank of England (BoE) and the Bank of Japan (BoJ) each meet on a published schedule, usually every 6-8 weeks. Their decisions affect USD, EUR, GBP and JPY and, through them, nearly every other market.

The words that matter

Traders read the statement for changes in wording: "data dependent", "restrictive for longer", "patient". A tone that is more hawkish (favouring higher rates) than expected tends to lift the currency; a more dovish tone weakens it.

How to use it

Know the next meeting dates, follow inflation and jobs data that change expectations and avoid sizeable positions through decisions unless you accept the volatility. You can follow current rates on our fundamental page.

Example: reading a statement

The previous statement said inflation risks were "balanced". The new one says they are "tilted to the upside" and the chair declines to rule out another hike. Rates were unchanged, but the language is more hawkish than before.

The currency often rises on such a change in wording, even if the rate decision itself was a hold.

Tools beyond interest rates

Central banks also use forward guidance (telling markets what they expect to do), bond purchases or sales, reserve requirements and, occasionally, direct market intervention to support their currency. Intervention is rare but can move a currency by hundreds of pips in minutes, so it is a reason to respect stops on yen pairs near historic lows.

Key takeaways

Policy rates and guidance drive currencies.
Meetings follow a published calendar.
Wording changes move markets.
Respect event volatility.
