Brief Explanations:

Open market operations (OMO) involve the Federal Reserve buying or selling government securities from or to commercial banks. When the Fed buys securities, it pays the banks, which increases the banks' reserves. Conversely, when the Fed sells securities, it collects payment from the banks, which decreases their reserves. These changes in reserve levels directly determine the volume of funds that banks have at their disposal to issue new loans to consumers and businesses. While OMO eventually influences interest rates, its primary and immediate mechanism is the manipulation of the liquidity and supply of money within the banking system.
