In January 2007, the amount of "central bank money" was $750.5 billion while the amount of "commercial bank money" (in the M2 supply) was $6.33 trillion. The money multiplier is the amount of money that banks generate with each dollar of reserves. C The empirical evidence is thus clearly aligned against the traditional belief about the workings of the money multiplier trillion.6 This simple comparison suggests that reservable deposits are in no way sufficient to fund bank lending. In fact, bank loans decline initially monetary transmission mechanism, Bernanke and Blinder estimate a monthly, six-variable VAR with the federal funds rate, consumer price index, bank loans, total deposits, bank securities, and the unemployment rate. earlier sample (more than three times as much), the relative share of large time deposits increased substantially as the share of transaction deposits declined by the end of the sample. Y 2000. continue to refer to the very narrow money multiplier and accord it a principle role in the transmission of monetary policy. If a depository institution's customers deposit more funds in their checking accounts, that depository institution is required to hold a higher level of reserves. Most simply, it can be defined either as the statistic of "commercial bank money"/"central bank money", based on the actual observed quantities of various empirical measures of money supply, such as M2 (broad money) over M0 (base money), or it can be the theoretical "maximum commercial bank money/central bank money" ratio, defined as . cause reserves (row 1, column 2). According to the standard multiplier theory, an increase in bank lending is associated with an increase in demand deposits. This process continues multiple times, and is called the multiplier effect. loans or invests causes the money The increase in the oney is either M currency oney held = Supply by the public C+D. + C Y (2004), Meltzer (2001) and most notably, the European Central Bank, put serious weight on the role of money in the macroeconomy and policy analysis. so this paper will not address which sectors of the economy are affected by monetary policy. "Bank Core Deposits and the Mitigation of Monetary Policy." The data appendix describes the construction of our key series in detail.18. Therefore, the response of reservable deposits is not expected to be different when we suppress bank loans. Our quarterly VAR (using quarter-end values) includes the federal funds rate, GDP deflator, securities, loans, transaction deposits, large time deposits, and the unemployment rate. The upper panel in Figure 8 shows the response of managed liabilities. In these results, there is some evidence that funding is not completely frictionless and that a bank's balance sheet does, in fact matter. our sample in 1994:Q1 and end it shortly before the beginning of the crisis in 2007:Q2.17 We use large time deposits as a proxy for managed liabilities and www.people.hbs.edu/dscharfstein/Lending_During_the_Crisis.pdf. Table 1 presents results of Granger causality tests. Hamilton, James. = Instead, it seems to be the case that small banks sell securities and issue large time deposits to offset the decline in their transaction deposits and meet the increased demand for loans. . Nevertheless, it is the link between money and reserves that drives the theoretical money multiplier relationship. The simple theoretical model developed by Jayaratne and Morgan (2000) serves well for our purposes. the level of reserve balances is expected to have an impact on the economy, it seems unlikely that a standard multiplier story will explain the effect. Nevertheless, it is not entirely clear what is behind the decline in bank loans for the less liquid Additionally, money market mutual funds account for about one-fifth of M2, but are not on Because these liabilities are not subject to reserve requirements, the textbook story of the money multiplier cannot be the operative channel of policy transmission. 2008. Despite this increase by a factor of 50, no similar increase in any measure of money, as The fact that part of M2, retail money funds, is not on depository institutions' books is not relevant for this comparison. Some variant of the money multiplier, then, may be operative only for these banks. t A This information alone suggests that banks' ability to raise large time deposits increased drastically over the last decade consistent with our earlier discussion about changes to the regulatory environment. 2 try to offset this decline in liabilities by raising large time deposits (row three). Despite the increase in bank loans following a tightening (second row, first column), there is a decline in total nonfinancial borrowing (second row, second column), a result that is consistent with the asymmetric information If a $1 increase in M0 by the Federal Reserve causes M2 to increase by $10, then the money multiplier is 10. Hafer, Rik, Haslag, Joseph, and Jones, Garett. 19. may be due to a decrease in non-bank sources of funding. The observed differences in the response of bank "Lending During the Financial Crisis of 2008." "Is There a Bank Lending Channel for Monetary Policy?" increase in managed liabilities declines if the CD rate is kept constant but the difference is mostly insignificant. In other words, a positive shock to loan demand (that is an increase in increases the equilibrium quantity of loans: Consequently, if contractionary monetary policy triggers an increase in loan demand, the money multiplier mechanism, which predicts a decline in loans or securities, fails. = transmission mechanism, we want to ask if there is a direct link from reserve balances to money or lending. Furthermore, the removal of interest rate ceilings through Regulation Q significantly improved the ability of banks to generate non-reservable liabilities by offering competitive rates on large time deposits. , the particular solution) is easily solved by letting Finally, the assumed link in the textbook version of the money multiplier between the creation of loans and the creation of demand deposits is dubious. We also run Granger Causality tests with lags of CPI (in difference form) included for comparability with the previous literature. p American Economic Review, 90: 1125-1135. following a contractionary shock and hover around zero for large and medium banks (columns one and two) whereas they increase substantially for small banks (column three). 1 If small banks had difficulties in raising nonreservable deposits, and if bank loans were indeed a dependent on transaction The exceptions in this class of models are those where the positive trend in C&I loans over that sample period (not shown), one can conclude that total loans under commitment increased significantly over the last decade, which was not prevalent in Bernanke and Blinder's sample. They also tend to reduce securities holdings less than other banks (row four). , or: The complementary function, Our findings suggest that this is not the case. t where Answer 36 : Money multiplier is defined as the reciprocal of the required reserve ra . In a recent paper, Ivashina and Scharfstein (2008) underlined this phenomenon by pointing to the rise in commercial and industrial (C&I) loans around the bankruptcy of Lehman Brothers during the recent financial turmoil. were about $43 billion, the tight link drawn in the textbook transmission mechanism from reserves to money and bank lending seems all the more tenuous. Our results with the aggregate data remain mostly unchanged when we restrict the sample to the post-1994 period, although the increase in total loans is less pronounced. This classification divides the sample into three comparable sized bins.21. Figure 6 shows the results from this exercise. Keynesian economists often calculate multipliers that measure the effect on aggregate demand only. Further complicating the story is the fact that required reserves and the reserves held by banks at the Federal Reserves, which we refer to as reserve balances, are different concepts.8 The lower panel in Figure 2 shows the level of reserve balances as the dotted line. "Money and Monetary Policy: An Essay in Honor of Darryl Francis." 0 C Note that the banks with the least liquid balance sheets do not decrease their securities as much, while the banks with the most liquid balance sheets sell off their securities more than the other banks to link between reserves and money--as defined as M2. Banks do not have an active role in controlling reservable deposits because their customers tend to determine how much money to keep in 1998. . Since the 1980s, two broad transmission mechanisms have been discussed: an "interest-rate" or "money channel," in which interest rates adjust to clear markets and influence borrowing and lending behavior; and a The US Reserve requirement is ten percent, yet because of leakage, the Federal Reserve Band of St. Louis estimates the M1 multiplier is closer to one! This is because if you have deposits of 1 million and a reserve ratio of 5%. We run the Granger causality tests in both log levels and in differences. People and banks retain an average 25 percent of their deposits. The multiplier effect on the money supply is governed by the following formulas: = : definitional relationship between monetary base MB (bank reserves plus currency held by the non-bank public) and the narrowly defined money supply, , seem to be associated with the decline in transaction deposits. If you had a reserve ratio of 5%. Furthermore, the partial derivative of bank If bank size alone does not determine a bank's ability to raise nonreservable deposits, what other factors could? We group banks based on whether their securities to assets ratio is less than 20 percent (least liquid), between 20 and 30 percent (liquid), and more than 30 percent (most liquid) in each quarter. Bernanke and Blinder (1988) and Kashyap and Stein (1995) note that the bank lending channel is not operative if banks have access to external sources of funding. tightening (Figure 4). c "New Evidence on the Monetary Transmission Mechanism," Brookings Papers on Economic Activity, 149-198. Merchants accepted gold receipts as a means of payment even though the receipts were issued by goldsmiths, not the government, because the government's currency could not be trusted. (row four), in contrast to the predictions of the bank lending channel. In theory, we can predict the size of the money multiplier by knowing the reserve ratio. Under the fractional reserve banking system, a unit of cash injected into the system by a central bank increases as it propagates through the banking system. t The argument against the textbook money multiplier is not new. link between reserves and loans.7. borrowing, reservable deposits, managed liabilities, securities, and funds rate. + Open market operations adjust the level of reserve balances, so to understand the Required reserves, however, fell dramatically just after 1990 following the reduction in required reserve ratios and trended down through 2000, largely as retail sweep programs allowed depository institutions to reduce their reserve requirements. Money Supply is measured and expressed using different monetary aggregates like M1, M2, M3, M4 etc. consumer price index. r holding checking accounts, similar to the response of total deposits in Bernanke and Blinder. We cannot reject the hypothesis that reserves do not Granger cause reservable liabilities (row 2, column = Variables are ordered as they are listed in the VAR specifications in each column heading. The multiplier may vary across countries, and will also vary depending on what measures of money are being considered. Open the link to. Jayarante, Jith, and Donald Morgan. these institutions lead to oscillating series. 2 A is themonetary bank its excess reserves to one-dollar increase supply to increase by oney supply is them earn m in the ore oney ore interest. The upper panel shows the results when the variables are in log levels and the lower panel shows the results when the variables are in first differences. For this sample, we substitute large time deposits (Deposits_Lg) for the series relative to each other. Moreover, OMOs affect Federal Reserve balances owned by the banking sector, not required reserves specifically. deposits. Figure 3 shows the results from the impulse response analysis to a funds rate shock. The most simple money multiplier described in textbooks links reservable deposits to bank reserves according to equation (1): where refers to changes in total reserves, refers to changes in when the federal funds rate was at its effective lower bound. If we take these results completely literally, bank loans increase rather than decrease in response to a decrease in reservable deposits. multiplier theory assumes that the lender bank puts the loan proceeds into the borrower's checking account. who point out the importance of globalization as a way to insulate the banks from domestic monetary policy shocks. and The upper panel shows that managed liabilities rise immediately in response to an increase in bank loans whereas the increase in reservable deposits is barely significant and short-lived, reinforcing the notion that it is The effect of reserve balances in simple Balance sheet variables are normalized by the GDP deflator and are in log form. "What Do a Million Observations on Banks say About the Transmission of Monetary Policy?" It is also sometimes called monetary multiplier or credit multiplier. 6. Our results, therefore, are not out of the mainstream. example Kashyap and Stein (2000) and Kishan and Opelia (2000)). note that inclusion of A second issue involves the effect of the large volume of reserves created as we buy assets. The appendix illustrates these relationships with a simple model. p t We consider a panel VAR to exploit the bank level data and yet preserve our methodology from the previous section. Because loans and managed liabilities in a real sense If there is a dominant group that has easier access to external finance, does bank size, bank liquidity (see Kashyap and Stein, 2000), bank In this paper, we tested the existence of a bank lending channel by checking whether or not bank loans are a function of reservable deposits. a money multiplier signifies the ratio of the money supply to the monetary base. c 2 *The month that corresponds to September 11, 2001 is excluded from the sample. Define money multiplier Money multiplier is defined as the number of dollars of money supply that can be created from each dollar of monetary base. Nevertheless the Meanwhile, changes in loans do not Granger cause managed liabilities but large time deposits (rows 5 and 6, column 3). It represents how a single dollar deposited in a bank can 'multiply' into a greater amount in the economy . The Survey of Terms of Business Lending notes that the percentage of C&I loans made under commitment remained stable around 70 to 80 percent from 1982 generally greater than the simple multiplier. Y If this characterization is accurate, these managed liabilities and loans should move together, but the ability to distinguish between statistical causality and true causality is difficult (we address this issue in more detail in the next section). The dashed lines represent 95 percent confidence intervals computed by bootstrap method. t = The multiplier effect is an economic term, referring to the proportional amount of increase, or decrease, in final income that results from an injection, or withdrawal, of capital. loans to monetary policy seem to be driven by demand factors. Freeman, Scott, and Kydland, Finn. 3, while the line with hollow circles and the line with stars plot the impulse response functions with managed liabilities and reservable deposits suppressed respectively. respectively, then substituting these in: or, rearranging and rewriting as a second order linear difference equation: The solution to this system then becomes elementary. loans with respect to a shock to loan demand is positive. Definition of Money Supply Money Supply can be defined as the money circulating in an economy. particular bank switches to a different size category for less than three quarters, then it will not have sufficient history to have two lags for the VAR estimation and will be automatically dropped from the sample. and results are virtually unchanged under alternative orderings. explain this increase? It is plausible to expect contractionary monetary policy to be more binding for smaller banks because "these banks are least likely to be able to bank lending. and respectively. 1992. For example, if an increase in German government spending by 100, with no change in tax rates, causes German GDP to increase by 150, then the spending multiplier is 1.5. {\displaystyle Y_{c}} If a variable has a significant role in A priori, it is hard to see why this is necessarily the case, given that these banks do not constitute a larger share in the universe of all banks, as indicated in Table 4. or bank deposits:The held (lower left panel). conditions and the above equations determine the equilibrium quantities of reservable deposits, managed liabilities, and loans: They consider a case where banks only make loans, . panel analysis, we control for bank-specific fixed effects. These temporary fluctuations are dropped from estimation. Once again, the relative sizes of the three groups are comparable.22 Figure 12 shows the impulse responses to a funds rate shock for the three groups. "Putting `M' Back into Monetary Policy." 2008. Journal of Money, Credit, and Banking, 40: 1-24. 2001. That is to say, the causality is unidirectional, from deposits to reserves. Similarly, we cannot reject the hypothesis that loans do not Granger cause reservable liabilities (row 2, column 3) either. After putting aside a part of these deposits as mandated bank reserves, the balance is available for the making of further loans by the bank. Specifically, if a Y t The marginal cost of reservable deposits and managed liabilities are: Finally, reservable liabilities fund only a small fraction of bank lending and the evidence suggests that they are not the marginal source of funding, either. covers January 1990 to June 2007, which corresponds to the most recent interest rate targeting regime.11 We intentionally excluded data from the financial This assumption ensures that banks fund their marginal It can simply be defined as the ratio of commercial bank money/central bank money. 1998. through the standard money multiplier model from reserves to money and bank loans. While banks in all three liquidity categories raise significantly more large time deposits to shield against the loss in reservable deposits, the negative relationship is most exception is bank capital, which is one of the four entries in the Call Reports that is allowed to be negative. We conclude that the textbook treatment of money in the transmission mechanism can be rejected. Each cell shows the p-values from pairwise Granger causality tests where the dependent This topic is also taught in class 12 Economics! Federal Reserve Bank of St. Louis, Review, July/August: 23-31. A more general but perhaps less rigorously derived multiplier links the monetary base to broader monetary aggregates (such as M2) to the monetary base according to: 4. Similarly, the relationship between bank loans and transaction deposits is negative for the least liquid banks who had experienced a decline in their loans bank balance sheets, and thus they cannot be used to fund lending. M2 trends upward, growing in nominal terms with the economy. {\displaystyle Y=Y_{c}+Y_{p}}, Opponents of Keynesianism have sometimes argued that Keynesian multiplier calculations are misleading; for example, according to the theory of Ricardian equivalence, it is impossible to calculate the effect of deficit-financed government spending on demand without specifying how people expect the deficit to be paid off in the future. The simple multiplier abstracts from excess reserves and currency. monetary policy, measures employed by governments to influence economic activity, specifically by manipulating the supplies of money and credit and by altering rates of interest. variables contemporaneously at a quarterly frequency. 1 Another way of understanding the role of reservable deposits and managed liabilities in funding bank loans is to consider what happens to impulse response functions when their roles are independently Indeed, at the other extreme, many economics textbooks and some academic research, such as Freeman and Kydland (2000) or Diamond and Rajan (2006) deposits, M2). Since 2008, the Federal Reserve has supplied an enormous quantity of reserve balances relative to historical levels as a result of a set of nontraditional policy actions. It tells the maximum number of times the amount will be increased with respect to the given change in the deposits.
