How interest rate decisions move currencies

Interest rates are the single most important long-run driver of exchange rates, and central bank decisions are the most closely watched events on the economic calendar.

Why interest rates matter for currencies

Money tends to flow towards higher returns. When one country's interest rates rise relative to another's, deposits and bonds in its currency become more attractive, and investors need that currency to buy them. The gap between two countries' rates is called the interest rate differential, and changes in it are a major reason currency pairs trend.

Expectations do most of the work

Markets price in expected rate changes long before they happen, using futures and swap markets. By decision day, a widely expected move is usually already in the price. That is why:

• A hike that was fully expected can leave the currency unchanged, or even weaker if the central bank signals that it is the last one.
• A hold can strengthen a currency if markets had expected a cut.

The market reacts to the surprise and to what the decision implies for future meetings.

What to read beyond the rate

1. The statement. Compare its wording with the previous one line by line. A single changed phrase about inflation risks can matter more than the decision.
2. The vote. A split vote, like the Bank of England's 6–3 decision in July 2026, tells markets which way the next move might go.
3. Projections. Some central banks publish forecasts for inflation, growth and even their own rates, such as the Federal Reserve's dot plot.
4. The press conference. Unscripted answers often move markets more than the prepared statement.
5. Minutes, published weeks later at some central banks, can revive a debate.

Hawkish and dovish

• Hawkish means leaning towards higher rates to fight inflation. Usually supportive for the currency.
• Dovish means leaning towards lower rates to support growth. Usually negative for the currency.

How often central banks meet

• Federal Reserve: 8 times a year
• European Central Bank: 8 times a year
• Bank of England: 8 times a year
• Bank of Japan: 8 times a year
• Reserve Bank of Australia: 8 times a year
• Bank of Canada: 8 times a year
• Reserve Bank of New Zealand: 7 times a year
• Swiss National Bank: 4 times a year

Rates are not the only driver

Risk sentiment, trade flows, energy prices and intervention can all overwhelm the rate story for a while. The yen, for example, often strengthens during market stress despite low Japanese rates; see safe-haven currencies.
