<p><b>New page</b></p><div>'''Open market operations''' ('''OMO''') are the purchase and sale of government securities—usually short-term government bonds—by a [[central bank]] in the open market. They are the most frequently used instrument of [[monetary policy]] in modern economies, by which the central bank adjusts the supply of bank reserves and thereby influences short-term [[interest rate]]s.<ref name="wiki">Wikipedia contributors, "Open market operation".</ref><br />
<br />
== Definition ==<br />
<br />
In an open market operation, the central bank buys or sells securities from or to banks and financial institutions. These transactions change the volume of reserves in the banking system, which in turn affects the interest rate at which banks lend to one another and, ultimately, a broad range of interest rates in the economy.<ref name="wiki"/><br />

== Advantages ==<br />
<br />
Open market operations are preferred by many central banks because they are:<br />
<br />
* '''Flexible''' — they can be conducted in any volume on a daily basis.<br />
* '''Reversible''' — the effects can be offset by opposite operations.<br />
* '''Precise''' — they allow fine-tuning of liquidity conditions.<br />
* '''Non-disruptive''' — they do not require changes to reserve requirements or lending facilities.<br />
<br />
== Related instruments ==<br />
<br />
Open market operations are complemented by other tools, including the [[Deposit Reserve Ratio]] and the [[Rediscount Rate]]. During periods when short-term interest rates reach the zero lower bound, central banks may employ '''unconventional''' open market operations, such as large-scale asset purchases ([[quantitative easing]]).<ref name="wiki"/><br />
