The U.S. Dollar’s Global Roles: Where Do Things Stand?

Linda S. Goldberg and Robert Lerman



Previous Liberty Street Economics analysis and New York Fed research addressed the potential implications for the United States if the dollar’s global role changed, noting that the currency might not retain its dominance forever. This post checks the status of the dollar, considering whether any erosion in the dollar’s international standing has occurred. The evidence to date is that the dollar remains the world’s dominant currency by broad margins. Alternatives have not gained extensive traction, albeit this does not rule out potential future pressures.

Post-Crisis Financial Regulation: Experiences from Both Sides of the Atlantic

Nicola Cetorelli, Stephanie Clampitt, Giovanni Majnoni d’Intignano, and Valerio Vacca



To mark the 100-year anniversary of the Banca d’Italia’s New York office, the Federal Reserve Bank of New York and the Banca d’Italia hosted a workshop on post-crisis financial regulation in November 2018. The goal of the workshop was to discuss differences in regulation between the United States and Europe (and around the globe more broadly), examine gaps in current regulations, identify challenges to be addressed, and raise awareness about the unintended consequences of regulation. The workshop included presentations by researchers from the U.S. and Europe on such topics as market liquidity, funding, and capital requirements. In this post, we present some of the findings and discussions from the workshop.

How Do the Fed's MBS Purchases Affect Credit Allocation?

Antoine Martin and Sam Schulhofer-Wohl



It is sometimes said that the Federal Reserve should not engage in “credit allocation.” But what does credit allocation actually mean? And how do current Fed policies affect the allocation of credit? In this post, we describe two separate ideas often associated with credit allocation. The first idea is that the Fed should not take credit risk, which taxpayers would ultimately have to bear. The second idea is that the Fed’s actions should not influence the flow of credit to particular sectors. We consider whether the Fed’s holdings of agency mortgage-backed securities (MBS) could affect the allocation of credit. In a companion post, we discuss how the economic effects of the Fed’s MBS holdings compare with the economic effects of more traditional holdings.

Size Is Not All: Distribution of Bank Reserves and Fed Funds Dynamics

Gara Afonso, Roc Armenter, and Benjamin Lester



As a consequence of the Federal Reserve’s large-scale asset purchases from 2008-14, banks’ reserve balances at the Fed have increased dramatically, rising from $10 billion in March 2008 to more than $2 trillion currently. In that new environment of abundant reserves, the FOMC put in place a framework for controlling the fed funds rate, using the interest rate that it offered to banks and a different, lower interest rate that it offered to non-banks (and banks). Now that the Fed has begun to gradually reduce its asset holdings, aggregate reserves are shrinking as well, and an important question becomes: How does a change in the level of aggregate reserves affect trading in the fed funds market? In our recent paper, we show that the answer depends not just on the aggregate size of reserve balances, as is sometimes assumed, but also on how reserves are distributed among banks. In particular, we show that a measure of the typical trade in the market known as the effective fed funds rate (EFFR) could rise above the rate paid on banks’ reserve balances if reserves remain heavily concentrated at just a few banks.

Note: This analysis provides insight into how the fed funds market might react to changes in the aggregate level of bank reserves. However, as it does not account for all relevant factors, it should not be construed as an analysis of any specific time period. In particular, our analysis does not incorporate the technical adjustment introduced by the FOMC on June 13 that lowered the interest paid on banks' reserves relative to the top of the target range.

Is Stigma Attached to the European Central Bank’s Marginal Lending Facility?

Helene Lee and Asani Sarkar




The European Central Bank (ECB)’s marginal lending facility has been used by banks to borrow funds both in normal times and during the crisis that started in 2007. In this post, we argue that how a central bank communicates the purpose of a facility is important in determining how users of the facility are perceived. In particular, the ECB never refers to the marginal lending facility as a back-up source of funds. The ECB’s neutral approach may be a key factor in explaining why financial institutions are less reluctant to use the marginal lending facility than the Fed’s discount window.

Hey, Economist! What Do Cryptocurrencies Have to Do with Trust?

Michael Lee and Antoine Martin




Bitcoin and other “cryptocurrencies” have been much in the news lately, in part because of their wild gyrations in value. Michael Lee and Antoine Martin, economists in the New York Fed’s Money and Payment Studies function, have been following cryptocurrencies and agreed to answer some questions about digital money.

Why Pay Interest on Excess Reserve Balances?

Laura Lipscomb, Antoine Martin, and Heather Wiggins



In a previous post, we described some reasons why it is beneficial to pay interest on required reserve balances. Here we turn to arguments in favor of paying interest on excess reserve balances. Former Federal Reserve Chairman Ben Bernanke and former Vice Chairman Donald Kohn recently discussed many potential benefits of paying interest on excess reserve balances and some common misunderstandings, including that paying interest on reserves restricts bank lending and provides a subsidy to banks. In this post, we focus primarily on benefits related to the efficiency of the payment system and the reduction in the need for the provision of credit by the Fed when operating in a framework of abundant reserves.

Counterparty and Collateral Policies of Central Bank Lending Facilities

Editor’s note: When this post was first published there was an omission in text; text has been restored. (August 16, 2017, 9:05 a.m.)



In a previous post, we compared the Federal Reserve’s discount window with the standing lending facilities (SLFs) at the Bank of England (BoE), the European Central Bank (ECB), and the Bank of Japan (BoJ). We showed that the Fed’s discount window was less integrated with monetary policy than the SLFs of the other central banks. In this post, we observe that the counterparty and collateral policies of the Fed’s discount window are similarly less integrated with the practices involved in monetary policy operations, in comparison with the other central banks.

A Closer Look at the Fed’s Balance Sheet Accounting

Deborah Leonard, Antoine Martin, and Jennifer Wolgemuth




An earlier post on how the Fed changes the size of its balance sheet prompted several questions from readers about the Federal Reserve’s accounting of asset purchases and the payment of principal by the Treasury on Treasury securities owned by the Fed. In this post, we provide a more detailed explanation of the accounting rules that govern these transactions.

How the Fed Changes the Size of Its Balance Sheet: The Case of Mortgage-Backed Securities

Deborah Leonard, Antoine Martin, Simon Potter, and Brett Rose



In our previous post, we considered balance sheet mechanics related to the Federal Reserve’s purchase and redemption of Treasury securities. These mechanics are fairly straightforward and help to illustrate the basic relationships among actors in the financial system. Here, we turn to transactions involving agency mortgage-backed securities (MBS), which are somewhat more complicated. We focus particularly on what happens when households pay down their mortgages, either through regular monthly amortizations or a large payment covering some or all of the outstanding balance, as might occur with a refinancing.
