How Bank Reserves Are Distributed Matters. How You Measure Their Distribution Matters Too.
Changes in the distribution of banks’ reserve balances are important since they may impact conditions in the federal funds market and alter trading dynamics in money markets more generally. In this post, we propose using the Lorenz curve and Gini coefficient as a new approach to measuring reserve concentration. Since 2013, concentration, as captured by the Lorenz curve and the Gini coefficient, has co-moved with aggregate reserves, decreasing as aggregate reserves declined (such as in 2015-18) and increasing as aggregate reserves increased (such as at the onset of the COVID-19 pandemic).
A New Reserves Regime? COVID‑19 and the Federal Reserve Balance Sheet
Aggregate reserves declined from nearly $3 trillion in August 2014 to $1.4 trillion in mid-September 2019, as the Federal Reserve normalized its balance sheet. This decline came to a halt in September 2019 when the Federal Reserve responded to turmoil in short-term money markets, with reserves fluctuating around $1.6 trillion in the early months of 2020. Then, in response to the COVID-19 pandemic, the Federal Reserve dramatically expanded its balance sheet, both directly, through outright purchases and repurchase agreements, and indirectly, as a consequence of the facilities to support market functioning and the flow of credit to the real economy. In this post, we characterize the increase in reserves between March and June 2020, describing changes to the distribution and concentration of reserves.
From Policy Rates to Market Rates—Untangling the U.S. Dollar Funding Market
How do changes in the rate that the Federal Reserve pays on reserves held by depository institutions affect rates in money markets in which the Fed does not participate? Through which channels do changes in the so-called administered rates reach rates in onshore and offshore U.S. dollar money markets? In this post, we answer these questions with the help of an interactive map that guides us through the web of interconnected relationships between the Fed, key market players, and the various instruments in the U.S. dollar funding market, highlighting the linkages across the short-term financial products that form this market.
