On March 23, 2006, the Board of Governors of the Federal Reserve System will cease publication of the M3 monetary aggregate. The Board will also cease publishing the following components: large-denomination time deposits, repurchase agreements (RPs), and Eurodollars. The Board will continue to publish institutional money market mutual funds as a memorandum item in this release.

Measures of large-denomination time deposits will continue to be published by the Board in the Flow of Funds Accounts (Z.1 release) on a quarterly basis and in the H.8 release on a weekly basis (for commercial banks).

M3 does not appear to convey any additional information about economic activity that is not already embodied in M2 and has not played a role in the monetary policy process for many years. Consequently, the Board judged that the costs of collecting the underlying data and publishing M3 outweigh the benefits.
