What is central bank intervention in forex?

Central bank intervention refers to the buying or selling of foreign currencies by a nation's central bank to influence its own currency’s exchange rate. The aim is often to stabilize markets, curb inflation, protect exports, or prevent capital outflows.

For example, the Reserve Bank of India (RBI) might sell US dollars to strengthen the rupee if it is depreciating too quickly.

Types of central bank interventions

• Direct intervention: Buying or selling currencies in the open market.
• Indirect intervention: Using tools like interest rate changes to influence currency demand.
• Verbal intervention: Making public statements to influence market expectations and sentiment.

These methods can be used independently or together depending on the urgency and objective.
