open market operation omo is a term that refers to the purchase and sale of securities in the open market by the federal reserve fed the fed conducts open market operations to regulate the supply of money that is on reserve in u s banks the fed purchases treasury securities to increase the money supply and sells them to reduce it by using omos the fed can adjust the federal funds rate which in turn influences other short term rates long term rates and foreign exchange rates this can change the amount of money and credit available in the economy and affect certain economic factors such as unemployment output and the costs of goods and services investopedia xiaojie liuunderstanding open market operations omos to understand open market operations you first have to understand how the fed the central bank of the u s implements the nation s monetary policy in an effort to keep the u s economy on an even keel and to forestall the ill effects of uncontrolled price inflation or deflation the board of governors of the federal reserve sets what s called a target federal funds rate 1the federal funds rate is the interest rate that depository institutions charge each other for overnight loans this constant flow of money allows banks to earn a return on excess cash in their fed balances while maintaining the reserves required to meet the demands of customers 2as a benchmark the federal funds rate influences a variety of other rates from savings deposit rates to home mortgage rates and credit card interest rates 1open market operations is one of the tools that the fed uses to keep the federal funds rate at its established target the u s central bank can lower the interest rate by purchasing securities and injecting money into the money supply similarly it can sell securities from its balance sheet take money out of circulation and put upward pressure on interest rates the board of governors of the federal reserve sets a target federal funds rate and then the federal open market committee fomc implements the open market operations to achieve that rate 3types of open market operationsthere are two types of omos permanent open market operations and temporary open market operations permanent open market operations refer to the fed s outright purchase or sale of securities for or from its portfolio permanent omos are used to achieve traditional goals for example the fed will adjust its holdings to put downward pressure on longer term interest rates and to improve financial conditions for consumers and businesses permanent omos are also used to reinvest principal received on currently held securities 4temporary open market operations are used to add or drain reserves available to the banking system on a short term basis they address reserve needs that are deemed to be transitory unlike permanent omos which involve outright purchases or sales temporary omos are temporary transactions they re either repurchase agreements repos or reverse repurchase agreements reverse repos 4a repo is a transaction where the fed s trading desk buys securities and agrees to sell them back at a future date a reverse repo involves the fed selling securities with the agreement that it will buy them back in the future overnight reverse repos are currently used by the fed to maintain the federal funds rate in its fomc established target range 4u s treasury securities or treasuries are government bills notes and bonds that are purchased by many individual consumers they re also purchased and held in large quantities by various types of financial institutions they are backed by the full faith and credit of the government and are considered a safe investment treasuries are first issued by the government and then traded in the secondary market expansionary and contractionary monetary policythe fed s monetary policy can be expansionary or contractionary 5if the fed s goal is to expand the money supply and boost demand the policy is expansionary the fed will buy treasuries to pour cash into the banks that encourages banks to lend the excess money that it doesn t have to keep in reserve out to consumers and businesses as the banks compete for customers interest rates drift downwards consumers are able to borrow more to buy more businesses are eager to borrow more to expand 5if the fed s goal is to contract the money supply and decrease demand the policy is contractionary the fed will sell treasuries to pull money out of the system less money in the economy means interest rates drift upwards and borrowing decreases consumers pull back on their spending businesses trim their plans for growth economic activity slows down 5benefits of open market operationsopen market operations allow the federal reserve or the central banks in other countries to prevent price inflation or deflation without directly interfering in the market economy instead of using regulations to control lending the fed can simply raise or lower the cost of borrowing money this allows the federal reserve to moderate the business cycle and reduce economic shocks during recessions the central bank lowers the cost of borrowing money encouraging business activity and growth in times of froth the fed increases the cost of borrowing money in order to rein in speculation and deflate potential bubbles open market operations can also be used to affect job growth by lowering interest rates the fed can make it easier to start businesses and hire workers resulting in increased employment example of open market operationsin 2019 the federal reserve used temporary omos term and overnight repos to support a healthy supply of bank reserves during what it referred to as periods of sharp increases in non reserve liabilities and to mitigate the risk of money market pressures that could adversely affect policy implementation 6it also used repos to counteract the stress caused by covid in 2020 and to ensure that banks could maintain plentiful amounts of reserves repos also helped accommodate the smooth functioning of short term u s dollar funding markets 6open market operations vs quantitative easingas discussed above open market operations is one of the fed s policy tools frequently used to expand the money supply and support economic activity or contact the money supply and slow that activity quantitative easing qe is an alternate non traditional tool that the fed also uses for monetary policy purposes essentially it involves the buying of securities on a very large scale to spur or steady the economy the fed normally employs quantitative easing after other monetary policy tools have been used but something more is needed to boost slow lending and economic activity for instance qe may be used when interest rates are already low but economic output is still less than what the fed believes is healthy
