Stability of funding models: an analytical framework
With the recent financial crisis, many financial intermediaries experienced strains created by declining asset values and a loss of funding sources. In reviewing these stress events, one notices that some arrangements appear to have been more stable?that is, better able to withstand shocks to their asset values and/or funding sources?than others. Because the precise determinants of this stability are not well understood, gaining a better grasp of them is a critical task for market participants and policymakers as they try to design more resilient arrangements and improve financial regulation. ...

Aggregate Liquidity Management
It has been largely acknowledged that monetary policy can affect borrowers and lenders differently. This paper investigates whether the distributional effects of monetary policy are an inherent feature of monetary economies with private credit instruments. In our framework, both money and credit instruments can potentially be used as media of exchange to overcome trading frictions in decentralized markets. Entrepreneurs have access to productive projects but face credit constraints due to limited pledgeability of their returns. Monetary policy affects the liquidity premium on private credit ...

On the fundamental reasons for bank fragility
A substantial body of literature has now developed as a result of efforts to identify the fundamental reasons for the fragility of financial intermediaries in the Diamond-Dybvig theory of banking. Many of these articles focus on the interaction between sequential service and uncertainty about the aggregate need for liquidity in the economy. The articles in this literature are inevitably technical and focus somewhat narrowly on the implications of specific assumptions. Here, we provide a more accessible discussion of the main ideas and findings in this literature. Our discussion can be used as ...

Should Central Banks Issue Digital Currency?
We study how the introduction of a central bank-issued digital currency affects interest rates, the level of economic activity, and welfare in an environment where both central bank money and private bank deposits are used in exchange. Banks in our model are financially constrained, and the liquidity premium on bank deposits affects the level of aggregate investment. We study the optimal design of a digital currency in this setting, including whether it should pay interest and how widely it should circulate. We highlight an important policy tradeoff: while a digital currency tends to promote ...

Bank runs and institutions : the perils of intervention
Governments typically respond to a run on the banking system by temporarily freezing deposits and by rescheduling payments to depositors. Depositors may even be required to demonstrate an urgent need for funds before being allowed to withdraw. We study ex post efficient policy responses to a bank run and the ex ante incentives these responses create. Given that a run is underway, the efficient response is typically not to freeze all remaining deposits, since this would impose heavy costs on individuals with urgent withdrawal needs. Instead, (benevolent) government institutions would allow ...

Why are banks holding so many excess reserves?
The buildup of reserves in the U.S. banking system during the financial crisis has fueled concerns that the Federal Reserve's policies may have failed to stimulate the flow of credit in the economy: banks, it appears, are amassing funds rather than lending them out. However, a careful examination of the balance sheet effects of central bank actions shows that the high level of reserves is simply a by-product of the Fed's new lending facilities and asset purchase programs. The total quantity of reserves in the banking system reflects the scale of the Fed's policy initiatives, but conveys no ...

Why are banks holding so many excess reserves?
The quantity of reserves in the U.S. banking system has risen dramatically since September 2008. Some commentators have expressed concern that this pattern indicates that the Federal Reserve's liquidity facilities have been ineffective in promoting the flow of credit to firms and households. Others have argued that the high level of reserves will be inflationary. We explain, through a series of examples, why banks are currently holding so many reserves. The examples show how the quantity of bank reserves is determined by the size of the Federal Reserve's policy initiatives and in no way ...

Bank runs and investment decisions revisited
We examine how the possibility of a bank run affects the deposit contract offered and the investment decisions made by a competitive bank. Cooper and Ross (1998) have shown that when the probability of a run is small, the bank will offer a contract that admits a bank-run equilibrium. We show that, in this case, the bank will chose to hold an amount of liquid reserves exactly equal to what withdrawal demand will be if a run does not occur. In other words, precautionary or "excess" liquidity will not be held. This result allows us to determine how the possibility of a bank run affects the ...

Can Redemption Fees Prevent Runs on Funds?
We ask whether imposing fees on redeeming investors can prevent runs on money market mutual funds (MMFs) and related intermediation arrangements. We first show that imposing a fee only in extraordinary times often leaves the fund susceptible to a preemptive run where investors rush to redeem before the fee applies. We then show how a policy that imposes a fee when current redemption demand is above a threshold, even in normal times, can make the fund run proof. We characterize the best policy of this type, which is immune to a run of any size. We show that the reform adopted in the U.S. in ...

Divorcing money from monetary policy
Many central banks implement monetary policy in a way that maintains a tight link between the stock of money and the short-term interest rate. In particular, their implementation procedures require that the supply of reserve balances be set precisely in order to implement the target interest rate. Because bank reserves play other key roles in the economy, this link can create tensions with other important objectives, especially in times of acute market stress. This article considers an alternative approach to monetary policy implementation -- known as a "floor system" -- that can reduce ...
