What Is an Interest Rate?
An interest rate is the cost of borrowing money, expressed as a percentage of the loan amount. It represents what a borrower pays a lender for the use of funds, and equally what a saver earns on deposited money. Interest rates can be fixed, staying the same over the term, or variable, changing in response to market conditions. They have a powerful influence on borrowing, saving, and investment returns.

The Role of Central Banks
Central banks set benchmark interest rates as a key tool of monetary policy. Raising rates can help cool an overheating economy and curb inflation, while lowering rates can encourage borrowing and support growth. These decisions ripple through the wider economy and financial markets.
Interest Rates and Currencies
Interest rates are a major driver of currency values. Higher rates can attract capital seeking better returns, which may strengthen a currency, while lower rates can have the opposite effect. Interest rate differentials between countries are central to many forex strategies.
The Market Impact of Rate Decisions
Interest rate announcements are among the most market-moving events on the economic calendar, and the reaction can be swift across currencies, bonds, and equities. Expectations are often priced in ahead of time, so surprises relative to forecasts can trigger sharp volatility. Traders should treat rate decisions and central bank guidance as high-impact events.
