18? Lecture at .of Banking, University of Wisconsin Madison, Wisconsin THE FUNCTION OF BANK RESERVES The term "bank reserves" is one that may have several meanings. It ay be used to refer to the total amount of reserves which qualify for meeting legal requirements of commercial banks or it may be used to include quick assets that banks hold as secondary reserves. Both commercial banks and the Federal Reserve Banks hold reserves but these are quite different in form. In our discussion today, when I refer to bank reserves shall in general be referring to the reserves that member banks hold on de posit with the Federal Reserve Banks, of which a part are legally required reserves and a part may be excess reserves. Nonmember bank reserves take several forms in accordance with various state laws, but the ulk of them are held in vault cash and on deposit with correspondent )Q nks. Reserves of the federal Reserve Banks consist of gold certificates held in their vaults. m For more than a century, it has been an accepted feature of the nation's banking system that commercial banks should be required to hold a certain fraction of their deposit or note liabilities in reserves. As °ur monetary and banking institutions have developed, however, our conception of the primary function of legal reserves of banks has undergone Sl gnificant change. Originally the principal purpose of legally required ^serves was to assure the ability of individual banks to meet liabilities demand during a period of strain. That is to say, it was to provide ° r the convertibility of bank notes and bank deposits into cash. With the establishment of the Federal Reserve System, the role of bank required reserves was greatly modified, and today they serve mainly to set a limit ° n ^ e total volume of bank, credit and the money supply. Reserve requirements against circulating bank notes became a part of American banking law a century ago, and requirements against bank deposits were introduced by the National Bank Act in 1863 and by two States even earlier. At first each bank's reserves comprised the specie in its own faults. Later these reserves came to include funds which a bank might have on deposit with another bank in a financial center. In the course of time it became evident that reserves alone were not adequate protection to banks and their depositors. The reserves which . a bank was legally required to maintain were not reserves which the bank could pay out. In other words, required reserves did not assure the abilof a bank to honor its obligations on demand. Moreover, since part these reserves was held on deposit with correspondent banks, their recall for meeting the demands of local depositors only transferred to the correspondent banks the problem of raising cash to liquidate banking system liabilities. In fact, in deposit withdrawal emergencies, outlying canks tended to rely on borrowing from their correspondent banks with whcm they maintained deposits. But these banks could use only their excess reserve^ for such lending, and the scattered excess reserves of the entire banking system were inadequate when a large number of banks were facing unusually heavy depositor withdrawals. an 188? Gradually it became more clearly understood that the ultimate siaf ty of bank deposits depended much more upon the availability of 8 reservo of reserve funds, to be drawn upon in case of need, than upon l e g a l reserves. That is, what was needed was an institution to provide additional money and reserves in emergencies; and, more important, to provide additional means of payment, under appropriate regulatory safeguards in accordance with the growth of agriculture, industry and commerce. The Federal Reserve System was established primarily to meet thes needs. The Reserve authorities were empowered to issue money. They ^ were also empowered to lend to member tanks or to buy United States uo eminent securities or certain kinds of commercial paper in the open ma ket, a process that creates member tank reserves in the form of niemter bank deposits at the Reserve banks. It was provided that member oanKS could not legally reduce their reserves below the statutory minimum a: since excess reserves do not produce income, it was. expected that mem, banks would not ordinarily keep excess reserves. The Federal R e s e r v e System, through its discount and open market instruments, was g i v e n a thority to exercise a regulatory influence over the volume of deposit which member bank lending and investing activities could create. These facts gave bank reserves and reserve requirements a new significance. Instead of serving largely as an individual bank's m a m guaranty of readiness to honor its obligations, they became the means\ j which the central banking authorities exert a restrictive or exp^sion^ influence, as public economic interest directs, on the ability of nan • to extend credit and expand deposits. Relationship of reserve requirements to the volume of deposits: The two factors I have just mentioned—the volume of tank r e s e r v e s and legal reserve requirements—serve as a team to set a limit to the total volume of deposits at any time. I shall have more to say la er about the volume of bank reserves. First, I should like to examine wi you, as I have before, the present-day role and significance of can/ i serve requirements—that is, the percentages of demand and time deposi that banks are required to hold as reserves. At existing levels of reserve requirements, one dollar of r e s e r v e s will support over 6 dollars of bank deposits. Stated in another^way, given addition to bank reserves makes possible about a six-fold in bank deposits. A contraction in reserves of a given amount tends ^ produce a six-fold contraction of deposits. The basic principle underlying this possible expansion and c o n t r a c tion is that tank deposits have their principal source in bank lending and investing. If there were only one bank in the country and it we c assume that peoole hold their money in the form of bank deposits, the bank could expand its deposits indefinitely by making loans to its customers and crediting the proceeds of the loans to its customer c h e c k i n g accounts. Being the only bank, it would not need to fear loss of depo> its to other banks. Those who receive checks drawn on the bank w o u l d deposit them at the bank,the effect w mid be merely a transfer of deposit ownership on the books. The only limitation on the expansion m 189? deposits would arise out of the amount of reserves in proportion to its deposits which the bank maintained, either because of its own rules or because of legal reserve requirements. At the present time member bank reserve requirements average about 15 per cent of total deposits. Fifteen per cent reserves permit deposits to expand about six and two-third w.mes. Thus, if there were but one large commercial bank serving the ene country and holding all the deposits of the people, its deposits could expand to £666 for each additional $100 of reserves. But we have not one bank but approximately M,000 commercial banks. herefore, in the actual competitive situation that exists no bank can expand its deposits by making by itself new loans and investments of six aes the amount of any newly acquired reserves. It can not do so bemuse bank customers do not borrow with the expectation of leaving the borrowed funds on deposit; they borrow in order to spend, and the 'funds 'hey borrow are more apt to be checked out to another bank than to remain with the bank which lent them. Consider an illustration of how credit and deposit expansion tends to occur, using an average reserve requirement for all banks of 15 per cent. When a bank receives a deoosit vlOO, it must put aside $15 as a reserve against the deposit and it can lend $85. When it has done this it has both the $100 deposit and tte W deposit put to the account of the borrower. But this £85 will probably be transferred by a payment to a depositor of a second bank. The second bank receiving the $85 deposit must increase its reserves by 15 Per cent of the deposit; that is $12.75. It then has $72.25 left which it can lend and which will probably find its way through a payment to a third bank. 1 This process may continue through a succession of banks, assuming a demand for bank credit, until taking all the banks together a result is reached which is the same as would be reached if there were only one bank. That is, all banks taken together constitute a system comparable £o a single bank performing all the banking business. Ceoosits may shift om bank to bank but, as a general thing, they do not leave the banking system. So, the process of lending and moving funds from bank to bank *ith resulting increases in deposits and in required reserves can continue through a succession of banks until the total of the new deposits, counting the original deposit of $100 at the first bank and the deposits created through the successive loans and investments, will amount to $666. ihe reserves set aside by the banks involved will total $100, which is the 15 per cent required against the aggregate deposit of $666. From this illustration we may draw two important generalizations. First, the lower the percentage reserve requirements of banks are, the greater the volume of credit and deposit expansion a given volume of additional reserves will support and the greater the volume of credit and deposit contraction a given loss of reserves will tend to require. Second, with our system of H,000 independent banks, legal reserve requirements at some level are an essential element in the mechanism through which the total volume of bank credit and deposits may be brought under some over-all control. Reserve requirements of the Federal Reserve Banks: I believe it is helpful for a fuller understanding of the modern role of commercial bank reserves to contrast the significance of commercial 190? reserve requirements and the requirements in gold certificate reserves applicable to the Federal Reserve Banks. It needs to be recognized that as far as reserve requirements are concerned, .as in other re soects, there are important differences between commercial banks and Federal Reserve Banks. As we have seen, the principal p r e s e n t - d a y nine tion of commercial bank reserves is as a mechanism through which tae total amount of m o n e y in the country may be influenced. What is the purpose or role of the reserve requirements imposed by law on the i'ea& Reserve Banks? bank The reserve of 25 per cent against deposit and note that the Federal Reserve Banks are required to hold in gold certificates na& importance in connection with two major kinds of functions performed uy the Federal Reserve System. Such reserve requirements could, m a F ^ of vast credit expansion, restrain the System from expanding Reserve w credit beyond a certain point. This would then tend to put an automata limit, although sometimes a high one, on the total monetary and creai> expansion that could take place. The System, however, does not expand i credit irresponsibly; substantial increases in Reserve Bank credit have been made only to meet national emergencies of depression and war. moi over, if the System were disposed to act in an irresponsible way to expand credit in a period of inflation, it has now more than enough leeway of excess reserves to cause very serious damage before its reserve lim would even begin to be effective. l i a b i l i t i e s While the limit on the expansion of Federal Reserve credit which i9 set by the gold reserve requirement is not an effective or necessary device for curbing monetary expansion, it may at some stage hincer tie ie era! Reserve in meeting a financial emergency. The System is the agency responsible for assuring the convertibility of bank deposits (and today perhaps I should also add Savings Bonds) into currency, should anything cause the peoole to want to hold currency rather than bank deposits or these other licuid .assets. The System also is responsible for providing needed elasticity in the supoly of available bank reserves. Tne r e s e r v e requirements on the Reserve Banks serve to limit their capacity to perform these functions. It seems to me that under the kind of a monetary and banking system we now have, there is no reason for any mechanical limitation on the capacity of the Federal Reserve to insure t h e c o n v e r t ! bility of bank deposits into currency or to extend needed credit „o meiber banks. influence over the volume of bank reserves: As I pointed out earlier, two factors limit t h e volume of d e p o s i t s that banks may create and hold: the volume of bank reserves, ana the 10 serve requirements of banks. When the volume of bank reserves i n c r e a s e s , banks as a group may expand their deposits by a multiple amount; conversely, a loss of reserves tends to induce a multiple contraction oi deposits. Thus if the Federal Reserve can influence the volume of b a n k reserves it can restrain or promote the expansion of bank deposits and help to bring about their proper adjustment to the needs of the economy. There are three principal instruments which the Federal Reserve System may employ to alter the volume of bank reserves. One means of control has been through changes in Reserve Bank rediscount rates. When a 191? aember bank has lent or invested all of its available funds, it may obtain additional reserves by rediscounting or borrowing at its Federal serve Bank. Although when a member bank applies for such accommodation l© Keserve Bank is under no obligation to grant credit, a member bank icv p l s f a c t o r y collateral can usually obtain it. Federal Keserve pol/ of encouraging or discouraging borrowing by member banks is expressed Principally not in the granting or refusing of loans but in the rate th f g e + !°r ^discounts and advances.

That is, it can enter the market at its n initiative to sell Government securities to contract Reserve Bank edit and to buy Government securities to expand that credit. Bank rerves may thus be contracted or expanded by the System as it seems in the Public interest to do so. ^gderal Reserve authority to change member bank reserve ^gguirements: — — ^ As you know, the Board of Governors has the power to vary the reserve quirements of member banks. The basic requirements established by law ain st demand deposits are 13, 10, and 7 per cent for central reserve c| reserve bv city, and country banks, respectively. These may be raised B a r d t o a m a x i m u i n o f 26 ° > and H per cent, respectively.

Under this authority, which expired e n d o f June , > the Board raised reserve requirements last September, lowered them in May and June. 192? The instrument of changes in reserve requirements is not one tha well adapted to frecment use for influencing the total volume ot bank credit and bank deposits. It is instead a measure to be used ' f to time as needed for contracting or expanding the. liquidity position the banking system and for bringing the other credit control instrume. of the Federal Reserve into broad contact with the credit situation, the period of financial reconversion from war through which we have n largely passed, however, changes in bank reserve reouirements assumea ceptional importance as an instrument for credit and inflation contro . This was the case because the System's other instruments for influence the total volume of money and credit were severely limited in use d/ special circumstances arising out of the financing of the war and tne absence of real oeace after the war. Recent developments, which X sn discuss shortly, indicate that perhaps greater emphasis may now saie j be placed on other monetary instruments and that the instrument otcna in reserve requirements may play a more balanced role in the tuture. Recent Federal Reserve Credit Action: A year ago, when I discussed the subject of bank reserves at a seminar session of this School of Banking, circumstances were such tna these Federal Reserve instruments for affecting the volume o, bank re serves were very severely limited in their usefulness. At that time, with financial transition to peace-time conditions only Partially aco plished and with the international situation es it was, stability in Government securities market was an overriding consideration. Open m ket operations, therefore, were not then usable for the purpose ot ax fecting aggressively the volume of bank reserves. For exercising som. measure of restraint on monetary expansion over the period ^ postwar flation, monetary authorities were obliged to rely on use of the then substantial Treasury cash surplus, cn a modest rise m short-term r*te and on increases in reserve requirements. By the end of last June circumstances were such that the Federal Open Market Committee was able to announce a change in policy vlucn w help to restore the effectiveness of certain traditional instruments i ^ influencing the volume of bank reserves. Purchases, sales, and excnar^ of Government securities are now made with primary regard to the business and credit situation. The policy of maintenance ot a ^ fixed pattern of rates has been discontinued, although it "ill to be the System's policy to maintain orderly conditions in the Govern ment security market, and the confidence of investors m Government conAbout the time the change in open market policy was announced, ex cess reserves of member banks were expanded approximately SOOmiiiioi lars by the expiration of the special reserve requirementauthority i Congress granted to the Board a year ago. These tree funds, seeking! vestment, pressed down the market yields on all Government ^ l ^ l l l d B but particularly short-term interest rates. After the short-term g e l had declined about \/U of 1 per cent it became clear that these rates were under such pressure that further precipitous declines w e r e likeiy, and the System made short-term Government securities, largely bills, available from its portfolio in order to avoid a disorderly market situation. 193? In early August the Board announced further reductions in reserve requirements, and over August and early September these reductions are waking available to member banks an additional 1,800 million dollars of excess reserves. Short-term Government securities, again primarily bills, being supplied in the market from the System portfolio so that banks way find a t least temporary investment for these funds without pressing down short-term yields to an undue extent. Generally speaking, the Board's reserve requirement actions coupled ith the change in open market policy of the System have had two major effects that should help to promote the availability of bank credit at this time. Member bank liquidity positions—that is, their holdings of cash, excess reserves, and short-term Government securities—have been expanded by about 2,600 million dollars. At the same time the yields on short-term Government securities are down considerably from what they w ere in the early summer, and accordingly the attractiveness of these investments is much reduced as compared with say a loan to a business concern or to a farmer. I should also mention the fact that the Reserve System is no longer freely selling Government bonds to keep their yields from declining. With the adoption of this policy by the System, pressure ef market forces brought about a decline in yields on medium, and longterm Government securities, with an accompanying tendency for investors to seek corporate and municipal securities as outlets for the funds they have available for investment. I believe that these credit actions by the Federal Reserve have had some influence in making the current economic situation somewhat more favorable than in general it promised to be a few months ago. y How_should the burden of holding reserves be distributed gmong banks? In order to keep the volume of money in the country at a level which is appropriate to economic conditions, we have seen that under our banksystem it is essential that banks be required to hold reserves, and that the Federal Reserve be able to influence the volume of reserves available to banks. At any given time, there is an appropriate volume of total reserves that banks as a group need to hold to promote monetary stability. But bank reserves are immobilized assets that cannot be loaned or invested to earn an income. The required reserves which an individual bank holds represent, therefore, a contribution which the bank makes to effective Rational monetary policy. The basis or principle for allocating the total burden of holding required reserves as among different banks thus becomes extremely important. The Federal Reserve System has studied the problem of allocating the reserve burden among banks for a long time. As you all doubtless know, the existing statutory basis for member bank reserve requirements dates back to the establishment of the National Banking System over 85 years a go. The requirements are related to the geographic location of the bank. That is, a bank's classification for reserve requirement purposes depends °n whether it is located in a central reserve city or in a reserve city, °r whether it is outside of these cities—a so-called country bank. A member bank, located for example in a reserve city must under this scheme bold reserves at the higher percentages designated for such a center whether or not it is doing a reserve banking type of business. Another 8? member bank doing a reserve banking business but located outside tner serve city areas need hold only country bank reserve requirements. *ro time to time the Federal Reserve has been able to relieve s o m e banks in reserve cities of a discriminatory reserve burden through its limited discretionary authority relating to outlying areas of re; many cases of ineauity cannot be solved in this way and a basic problem of equitv 0 ? reserve requirement treatment as among member banks st,m remains. There is also a fundamental problem of equity as between m e m b e r ^ nonmember banks, where the differences in treatment are frequ<antly very, very wide. Certainly from the standpoint of the reserves it must hold, the average nonmember bank is now making a disproportionately small ca tribution to monetary stability. The nonmember bank not on:iy is subje generally to much lower reserve requirements, bub it is also permittea hold its reserves at correspondent city banks where they serve a d o u W < ^ purpose—both as legal reserves and as a needed correspondent balance, member bank holds both a reserve balance in its with its correspondents. Further, the actual contrilbution to inonet.*ry control of a reserve balance held with a c o r r e s p o n d e n t bank is only equ to that fraction of the balance which the correspondent ban.c .s m turr obliged to hold with its Reserve Bank, since the c o r r e s p o n d e n t bank free to, and usually does, invest or lend the remainder In some stated moreover, nonmember banks are permitted to invest a portion of their r serves in interest bearing public securities. treafcmet, in favor of nonmember banks as far as reserve requirements are c o n c e r n * * tends to weaken the ability of the Federal Reserve to promote P^per ad iustraent of the volume of money to the needs of the economy. The large difference in the requirements tends to discourage banks from joining * System! and could result in weakening the System withdraw from membership. It is difficult to see the justification for discrimination of this kind. D i s c r i m i n a t o r y Uniform Reserve_Plan: • As I said a year ago at this School of Banking, a staff committee of the Federal Reserve System has developed a plan for rationalizing existing practices for distributing the reserve requirement buruen among banks. They have called the plan the Uniform Reserve Requirement plan, anS a; the request of the Joint Committee on Economic Report o f C o n g r e s s they presented to that Committee the results of their study. The suggestions of the Federal Reserve staff group are in the discussion;stage and have no official status in the System. I find the ideas in the plan very interesting, however, and I should like to tell you something about them. The plan deals only with member bank reserve J^ed it is adopted it could be, and I believe certainly should be, e x t e n d e d with appropriate modifications to cover all commercial banks. The Uniform Reserve Requirement plan consists of five basic points. These have been described by the chairman of the staff committee tnat developed the plan as follows: First, the plan would abolish central reserve city and r e s e r v e city designations of banks. In other words, the geographical basis ior the fs efsment of reserve requirements would be dropped as too i n e q u i t a b l e aS among banks which are doing various kinds of commercial banking business 195? . T3le second point of the plan is that, for purposes of reserve requirements, deposits would be classified into interbank deposits, other aemand deposits, and time deposits. Many a theoretical hair has been s Plit in disputes over the classification of deposits. The compelling practical objection to treating all deposits alike is that, depending on e level set, starting such a system would create enormous excess reserves in central reserve city banks, enormous deficiencies in non-reserve city banks, or both. The compelling practical objection to a full system deposit classification is that it would be impossible to administer, since any classification of deposits is somewhat arbitrary. Advantages given for the proposed classification are that, by and large, the three classes of deposits are used for different purposes, are readily identifiable, have traditionally been treated differently, and differential treatment would minimize initial disturbances while yet retaining effective over-all control. The staff committee recommended that initial requirements be established at 30 per cent against all interbank deposits, u per cent against other demand deposits, and 6 per cent against time eposits, which would have left the total volume of reauired reserves at about the level existing at the time. (Slightly lower requirements would a PPropriate of course should the plan be adopted now.) The third point of the plan is that the Federal Reserve should be given authority to change the requirements within limits established in he law, We have already discussed the use of changes in reserve requirements from time to time in order to help prevent injurious credit expansion or contraction. This is a modem instrument of central banking Policy which is discussed with approval in virtually every textbook on money and banking. As a fourth point, banks would be allowed to count vault cash as Part of their legal reserve. The role of vault cash in the banking system has changed fundamentally in the past half century. Before the Federal Reserve System was established, vault cash was the ultimate reserve cf the banking system, since it alone was available to meet cash withdrawals. The Federal Reserve Banks, however, are authorized to create additional reserves or cash when needed. The use of vault cash as reserves would not impair the System's influence over the volume of bank credit, provided initial requirements are established at appropriate levels to offset the change. From the point of view of credit control, here need be no concern as to the form of Federal Reserve Bank liability— ^hether it be Federal Reserve notes or reserve deposits—that a member cank prefers to hold a3 reserves. The transition to the new system of reserve requirements would be facilitated by permitting banks to count vault cash as legal reserves. Establishment of the suggested uniform requirement against other demand deoosits would increase required reserves oi - country banks. Since, however, such banks hold relatively larger amounts of vault cash the increase in their total requirements would be offset in part by permitting them to count vault cash as legal reserves. The fifth and last point is to permit a bank to count as reserves that portion of its balances held at other banks which those banks, in turn, are required to hold as reserves against such balances. The relationship between correspondent balances and reserves is a problem with a io ng history. After many discussions the staff concluded that correspondent ^balances ought to be related to reserves in such a way that (a) a shift of funds by member banks into or out of "due from banks" would not 196? the total volume of excess reserves in the system as a w h o l e , (b) "reserve credit" would be allowed for precisely the portion oi au from banks" that is on deoosit with Federal. Reserve B a n k s (by way oi reserve requirement imposed on deposits due to banks); and {o) corr spondent bank relationships and interbank balances would b e r e c o g n - e as an established part of our banking system. The fifth p o i n t is a e signed to accomplish this result. So long as the rate at which the "country" bank or the reserve city bank is allowed reserve credit 101 its "due from" balances is equal to the rate at which depositary ban** are required to maintain reserves on interbank deposits, a given res w i l l support the same volume of nonbank deposits irrespective of whe^ the owner-bank keeps all of its reserve with its Federal Reserve Bun*, or keeps a portion of it on deposit with a correspondent and thereioi indirectly with a Federal Reserve Bank. In either case, only vault and balances which are directly or indirectly on deposit with federal Reserve Banks would constitute legal reserves. affect The analysis of the Uniform Reserve Plan may be summarized as follows: Reserve retirements are an essential feature of the mechanism J * which the volume of money and credit is adjusted to the needs of tne economy but the present system of reserve requirements is freauent y equitable; required reserves of many banks are higher or lower than u of other banks doing a similar business simply because of the classi cation of the communities in which they are located. The uniform sys ^ of reserve requirements would require all member banks, or Prefeia^./ commercial banks, regardless of location, to maintain the same perc® ages of reserves against each of the three major classes of deposits interbank deposits, other demand deposits, and time deposits. BanKS whose business requires the holding of disproportionately large emom of vault cash would no longer be penalized by being required to ^ ^ the same reserves in Federal Reserve Banks as other banks doing a av lar type and volume of business but whose cash requirements vcro Changes in the total volume of interbank deposits would no longer the volume of other deposits of member banks that could b e s u p p o r t e d a piven volume of reserves. City banks would have to maintain large ^ reserves than now against balances due to country correspondents, t w latter would be given corresponding credits for such balances a g a i n e their reouired reserves. The uniform system would increase tne requ reserves for some banks and lower them for others, but the changes v be reasonable and in the direction of greater equity.
