Open market operations refer to the process by which the Central Bank of a country buys or sells securities in the open market in order to influence the money supply, interest rates, and ultimately, the overall economy. This involves the Central Bank purchasing or selling government securities, such as bonds or treasury bills, from or to commercial banks or other financial institutions. By doing so, the Central Bank can increase or decrease the amount of money in circulation, affecting the interest rates at which banks lend and borrow money from each other, and ultimately impacting the broader economy. Open market operations are one of the primary tools used by Central Banks to control inflation, stabilize the currency, and promote economic growth.
