The repo rate is the interest rate at which a central bank lends money to commercial banks overnight, backed by government securities or bonds. It's a core tool for controlling money supply and financial system liquidity.
When banks need short-term funding, they access the central bank's repo facility. A higher repo rate makes this borrowing more expensive, causing banks to reduce lending and contract the money supply. A lower rate encourages borrowing and credit expansion.
For forex traders, repo rate changes matter because they affect currency valuations. Higher rates typically strengthen a country's currency—they attract foreign investment seeking better returns—while lower rates tend to weaken it. Central bank announcements about repo rate decisions can trigger sharp currency moves, which is why traders track economic calendars closely.
The repo rate influences other market interest rates and signals the central bank's stance on inflation and economic growth. Understanding when and why a central bank might shift its repo rate helps traders anticipate currency volatility and identify trading opportunities.
