When the actual  Federal funds rate  is higher than the target, the New York Reserve Bank will usually increase the money supply via a repo  (effectively borrowing from the dealers' perspective; lending for the Reserve Bank). When the actual Federal funds rate is less than the target, the Bank will usually decrease the money supply via a  reverse repo  (effectively lending from the dealers' perspective; borrowing for the Reserve Bank).Federal Reserve  most commonly uses overnight  repurchase agreements  (repos) to temporarily create money, or reverse repos to temporarily destroy money, which offset temporary changes in the level of bank reserves. [4]  The Federal Reserve also makes outright purchases and sales of securities through the System Open Market Account (SOMA) with its manager over the Trading Desk at the New York Reserve Bank. The trade of securities in the SOMA changes the balance of bank reserves, which also affects short term interest rates. The SOMA manager is responsible for trades that result in a short term interest rate near the target rate set by the Federal Open Market Committee  (FOMC), or create money by the outright purchase of securities. [5]  Very rarely will it permanently destroy money by the outright sale of securities.[ citation needed  ] These trades are made with a group of about 22 (currently 18 as an immediate aftermath of 08/09 credit crisis) banks or bond dealers that are called  primary dealers .Federal Reserve Bank of New York , under the direction of the  Federal Open Market Committee . The open market operation is also a means through which inflation can be controlled because when treasury bills are sold to commercial banks these banks can no longer give out loans to the public for the period and therefore money is being reduced from circulation.en.wikipedia.org
