Interest Rate
The cost of borrowing money, set by central banks.
Full Definition
Interest rates are the cost of borrowing money, set by central banks through their policy rates. They significantly impact currency values because investors, corporations, and governments move capital across borders in search of higher returns. Higher rates attract foreign investment seeking better yields, strengthening the currency. Lower rates make borrowing cheaper but reduce yield appeal, typically weakening the currency.
Rate decisions by the Federal Reserve, European Central Bank, Bank of Japan, Bank of England, and other major central banks are among the most significant market-moving events on any forex calendar. Markets price in expectations ahead of meetings, so the actual currency reaction depends more on how the decision compares to expectations than on the absolute rate change. A 25 basis point hike that is fully expected may produce little currency movement, while an unexpected pause can produce dramatic swings in minutes.
For example, when the Federal Reserve raised rates from near zero to above 5 percent between 2022 and 2023 while the Bank of Japan kept rates near zero, the interest rate differential drove the US dollar sharply higher against the yen. USD/JPY rose from around 115.00 to above 150.00, a 3,500 pip move. A trader long 1 standard lot through that trend captured roughly $23,000 in unrealized gains before fees, driven almost entirely by the policy divergence.
