Federal Reserve Actions Affecting Its Holdings of U.S. Government Securities
In discussing various factors that affect reserves, it was often indicated that the Federal Reserve offsets undesired changes in reserves through open market operations, that is, by buying and selling U.S. government securities in the market. However, outright purchases and sales of securities by the Federal Reserve in the market occur infrequently, and typically are conducted when an increase or decrease in another factor is expected to persist for some time. Most market actions taken to implement changes in monetary policy or to offset changes in other factors are accomplished through the use of transactions that change reserves temporarily. In addition, there are off-market transactions the Federal Reserve sometimes uses to change its holdings off U.S. government securities and affect reserves. (Recall the example in illustrations 38 and 40). The impact on reserves of various Federal Reserve transactions in U.S. government and federal agency securities is explained below. (See table for a summary).

38. When a Foreign Central Bank makes a dollar-denominated payment from its account at the Federal Reserve, the recipient deposits the funds in a U.S. bank. As the payment order clears, U.S. bank reserves rise.

40. If the sell order is executed with the Federal Reserve's account, however, the increase in reserves from (38) will remain in place. The Federal Reserve might choose to execute the foreign customer's sell order with the System's account if an increase in reserves is desired for domestic policy reasons.

Outright transactions
Ownership of securities is transferred permanently to the buyer in an outright transaction, and the funds used in the transaction are transferred permanently to the seller. As a result, an outright purchase of securities by the Federal Reserve from a dealer in the market adds reserves permanently. The Federal Reserve can achieve the same net effect on reserves through off-market transactions where it executes outright sell and purchase orders from customers internally with the System account. In contrast, there is no impact on reserves if the Federal Reserve fills customers' outright sell and purchase orders in the market.
Temporary transactions
Repurchase agreements (RP's), and associated matched sale-purchase agreements (MSP's), transfer ownership of securities and use of funds temporarily. In an RP transaction, one party sells securities to another and agrees to buy them back on a specified future date. In an MSP transaction, one party buys securities from another and agrees to sell them back on a specified future date. In essence, then, an RP for one party in the transaction works like an MSP for the other party.
When the Federal Reserve executes what is referred to as "System RP," it acquires securities in the market from dealers who agree to buy them back on a specified future date 1 to 15 days later. Both the Systems portfolio of securities and bank reserves are increased during the term of the RP, but decline again when the dealers repurchase the securities. Thus System RP's increase reserves only temporarily. Reserves are drained temporarily when the Fed executes what is known as a "System MSP." A System MSP works like a System RP, only in the opposite direction. In a System MSP, the Fed sells securities to dealers in the market and agrees to buy them back on a specified day. The System's holdings of securities and bank reserves are reduced during the term of the MSP, but both increase when the Federal Reserve buys back the securities.
The Federal Reserve also uses MSP's to fill foreign customers' RP orders internally with the System account. Considered in isolation, a Federal Reserve MSP transaction with customers would drain reserves temporarily. However, these transactions occur every day, with the total amount of RP orders being fairly stable form day to day. Thus, on any given day, the Fed both buys back securities from customers to fulfill the prior day's MSP, and sells them back about the same amount of securities to satisfy that day's agreement. As a result, there generally is little or no impact on reserves when the Fed uses MSP's to fill customer RP orders internally with the System account. Sometimes, however, the Federal Reserve fills some of the RP orders internally and the rest in the market. The part that is passed on to the market is known as a "customer related RP." The Fed ends up repurchasing more securities from customers to complete the prior day's MSP than it sells to them in that day's MSP. As a result, customer related RP's add reserves temporarily.
Maturing securities
As securities held by the Federal Reserve mature, they are exchanged for new securities. Usually the total amount maturing is replaced so that there is no impact on reserves since the Fed's total holdings remain the same. Occasionally, however, the Federal Reserve will exchange only part of the amount maturing. Treasury deposits decline as payment for the redeemed securities is made, and reserves fall as the Treasury replenishes its deposits at the Fed through TT&L calls. The reserve drain is permanent. If the Fed were to buy more than the amount of securities maturing directly from the Treasury, then reserves would increase permanently. However, the Federal Reserve currently is prohibited by law from buying securities directly from the Treasury, except to replace maturing issues.

Miscellaneous Factors Affecting Bank Reserves
The factors described below normally have negligible effects on bank reserves because changes in them either occur very slowly or tend to be balanced by concurrent changes in other factors. But at times they may require offsetting action.
Treasury Currency Outstanding
Treasury currency outstanding consists of coins, silver certificates and U.S. notes originally issued by the Treasury, and other currency originally issued by commercial banks and by Federal Reserve Banks before July 1929 but for which the Treasury has redemption responsibility. Short-run changes are small, and their effects on bank reserves are indirect.
The amount of Treasury currency outstanding currently increases only through issuance of new coin. The Treasury ships new coin to the Federal Reserve Banks for credit to Treasury deposits there. These deposits will be drawn down again, however, as the Treasury makes expenditures. Checks issued against these deposits are paid out to the public. As individuals deposit these checks in banks, reserves increase. (See explanation on pages 18 and 19).
When any type of Treasury currency is retired, bank reserves decline. As banks turn in Treasury currency for redemption, they receive Federal Reserve notes or coin in exchange or a credit to their reserve accounts, leaving their total reserves (reserve balances and vault cash) initially unchanged. However, the Treasury's deposits in the Reserve Banks are changed when Treasury currency is retired. Transfers from TT&L balances in banks to the Reserve Banks replenish these deposits. Such transfers absorb reserves.
Treasury Cash Holdings
In addition to accounts in depository institutions and Federal Reserve Banks, the Treasury holds some currency in its own vaults. Changes in these holdings affect bank reserves just like changes in the Treasury's deposit account at the Reserve Banks. When Treasury holdings of currency increase, they do so at the expense of deposits in banks. As cash holdings of the Treasury decline, on the other hand, these funds move into bank deposits and increase bank reserves.
Other Deposits in Reserve Banks
Besides U.S. banks, the U.S. Treasury, and foreign central banks and governments there are some international organizations and certain U.S. government agencies that keep funds on deposit in the Federal Reserve Banks. In general, balances are built up through transfers of deposits held at U.S. banks. Such transfers may take place either directly, where these customers also have deposits in U.S. banks, or indirectly by the deposit of funds acquired from others who do have accounts at U.S. banks. Such transfers into "other deposits" drain reserves.
When these customers draw on their Federal Reserve balances (say, to purchase securities), these funds are paid to the public and deposited in U.S. banks, thus increasing bank reserves. Just like foreign customers, these "other" customers manage their balances at the Federal Reserve closely so that changes in their deposits tend to be small and have minimal net impact on reserves.
Non float-Related Adjustments
Certain adjustments are incorporated into published data on reserve balances to reflect non float-related corrections. Such a correction might be made, for example, if an individual bank had mistakenly reported fewer reservable deposits than actually existed and had held smaller reserve balances than necessary in some past period. To correct for this error, a non float-related as-of adjustment will be applied to the bank's reserve position. This essentially results in the bank having to hold higher balances in its reserve account in the current and/or future period reserve requirements.
Other Federal Reserve Accounts
Earlier sections of this booklet described the way in which bank reserves increase when the Federal Reserve purchases securities and decline when the Fed sells securities. The same results follow from any Federal Reserve expenditure or receipt. Every payment made by the Reserve Banks, in meeting expenses or acquiring any assets, affects deposits and bank reserves in the same way as does the payment to a dealer for government securities. Similarly, Reserve Bank receipts of interest on loans and securities and increases in paid-in capital absorb reserves.
