The Board of Governors discontinued the H.3 statistical release on September 17, 2020. For more information, please see the announcement posted on August 20, 2020.

Currency in circulation includes paper currency and coin held both by the public and in the vaults of depository institutions. The total includes Treasury estimates of coins outstanding and Treasury paper currency outstanding. This definition of currency in circulation differs from the currency component of the money stock, (CURRENCY), which excludes currency held in vaults of depository institutions.

Effective February 2, 1984, reserve computation and maintenance periods have been changed from weekly to bi-weekly. Series with data prior to February 2, 1984 have different values reported from one week to the next. After February 2, 1984, the value repeats for 2 consecutive weeks.

Release: H.6 Money Stock Measures  

Units:  Billions of Dollars, Seasonally Adjusted

Frequency:  Weekly, Ending Monday

Notes:

This weekly series is discontinued and will no longer be updated. The non-seasonally adjusted version of this weekly series is WM2NS, and the seasonally adjusted monthly series is M2SL.

Starting on February 23, 2021, the H.6 statistical release is now published at a monthly frequency and contains only monthly average data needed to construct the monetary aggregates. Weekly average, non-seasonally adjusted data will continue to be made available, while weekly average, seasonally adjusted data will no longer be provided. For further information about the changes to the H.6 Statistical Release, see the announcements provided by the source.

Before May 2020, M2 consists of M1 plus (1) savings deposits (including money market deposit accounts); (2) small-denomination time deposits (time deposits in amounts of less than $100,000) less individual retirement account (IRA) and Keogh balances at depository institutions; and (3) balances in retail money market funds (MMFs) less IRA and Keogh balances at MMFs.

Beginning May 2020, M2 consists of M1 plus (1) small-denomination time deposits (time deposits in amounts of less than $100,000) less IRA and Keogh balances at depository institutions; and (2) balances in retail MMFs less IRA and Keogh balances at MMFs. Seasonally adjusted M2 is constructed by summing savings deposits (before May 2020), small-denomination time deposits, and retail MMFs, each seasonally adjusted separately, and adding this result to seasonally adjusted M1. For more information on the H.6 release changes and the regulatory amendment that led to the creation of the other liquid deposits component and its inclusion in the M1 monetary aggregate, see the H.6 announcements and Technical Q&As posted on December 17, 2020.
