The Federal Reserve Board plans to issue an annual revision to the index of industrial production (IP) and the related measures of capacity and capacity utilization on March 27, 2009.

The Z.1 Flow of Funds statistical release was reposted on January 6, 2009 at 10:00 a.m. to correct errors on table L.108 lines 8 and 16 affecting data in 2008:Q3. Corrected data were made available through the Data Download Program on January 6, 2009 at 10:15 a.m.

The H.3 statistical release indicates that nonborrowed reserves of depository institutions were negative for much of 2008 but more recently have turned positive.

By definition, nonborrowed reserves are equal to total reserves minus borrowed reserves. Borrowed reserves are equal to the sum of credit extended through the Federal Reserve's regular discount window programs and credit extended through certain Federal Reserve liquidity facilities. Total borrowings from the Federal Reserve are presented in table 1a of the release. Over much of 2008, in order to maintain a level of total reserves consistent with the Federal Open Market Committee's objective for the federal funds rate, increases in borrowed reserves were offset through a nearly commensurate decrease in nonborrowed reserves, which was accomplished through a reduction in the Federal Reserve's holdings of securities and other assets. The negative level of nonborrowed reserves was an arithmetic result of the fact that borrowings from the Federal Reserve liquidity facilities were larger than total reserves.

More recently, nonborrowed reserves have again turned positive. This development is purely an arithmetic result, in this case of the fact that a large volume of reserves has recently been provided through channels that, for purposes of the Federal Reserve's statistical releases, are not considered borrowings. These channels include foreign currency swap arrangements with foreign central banks and certain special purpose vehicles. Credit extended to these special purpose vehicles are not shown on the Federal Reserve's balance sheet. Rather, as noted on the H.4.1 statistical release, the assets of these vehicles are consolidated onto the Federal Reserve's balance sheet, and consequently credit extended to these special purpose entities is not treated as a borrowing for purposes of the H.3 statistical release.

Capacity utilization rates for October 2007 through February 2008 have been updated with the G.17 Statistical Release published on September 15, 2008. In April 2008, a six-month reporting window was instituted for the industrial production indexes in the G.17 Statistical Release; however, the capacity utilization rates inadvertently continued to be calculated for only a four-month window. Table 7A shows the revised rates for the affected months. The download program and the historical data files on the Federal Reserve Board's website have been updated with revised data.

February 15, 2008: The data in this release include preliminary estimates of industrial capacity for 2008. Measured fourth quarter to fourth quarter, total industrial capacity is projected to rise 1.9 percent this year after having expanded 1.8 percent in 2007. Manufacturing capacity is estimated to increase 2.1 percent in 2008, the same amount as in 2007. In 2008, mining capacity is estimated to expand 0.7 percent, and utilities capacity is projected to rise 1.9 percent; both rates of increase would be slightly faster than for last year. With the publication on March 28, 2008, of the annual revision to industrial production, capacity, and capacity utilization, these estimates will be updated to reflect more-comprehensive source data, including the 2006 Survey of Plant Capacity, physical capacity data from government and trade sources, and the revised production indexes.

The H.3 statistical release indicates that nonborrowed reserves of depository institutions have declined substantially since mid-December to a level that is now negative. This development reflects the provision of a large volume of reserves through the Term Auction Facility (TAF) and has no adverse implications for the availability of reserves to the banking system.

By definition, nonborrowed reserves are equal to total reserves minus borrowed reserves. Borrowed reserves are equal to credit extended through the Federal Reserve's regular discount window programs as well as credit extended through the TAF. To maintain a level of total reserves consistent with the Federal Open Market Committee's target federal funds rate, increases in borrowed reserves must generally be met by a commensurate decrease in nonborrowed reserves, which is accomplished through a reduction in the Federal Reserve's holdings of securities and other assets. The negative level of nonborrowed reserves is an arithmetic result of the fact that TAF borrowings are larger than total reserves.

The above corrections have been made to the historical data. In addition, some earlier observations in the historical data have been corrected. However, these observations were published correctly on the original statistical releases.

The DDP values for 09/5/07 and 09/12/07 for Total borrowings of Depository Institutions from the Federal Reserve (RESBR14A_N.WW) have been updated to reflect the correct values as posted on the H.3 release and H.3 Weekly Historical Aggregate Table 6: Memorandum Items dated 09/13/2007.

The Z.1 Flow of Funds statistical release was reposted on March 8, 2007 at 5:21 PM to correct errors in components of federal government debt affecting data from 1970 forward. Corrected data were made available through the Data Download Program on March 9, 2007 at 10:30 AM.

As of the release dated February 25, 2002, the H.15 no longer reports a 30-year constant maturity yield for Treasury securities and begins reporting a yield for Treasury securities with 25 years or more remaining to maturity.

The changes reflect the Treasury's announcement on January 30, 2002, that, effective February 18, it would cease supplying an estimate of the 30-year constant maturity yield and that it would commence supplying a long-term yield based on a basket of long-dated securities.

As indicated in footnote 12 of the release, the new long-term rate is based on an unweighted average of the bid yields for all Treasury fixed-coupon securities with remaining terms to maturity of at least 25 years. A factor to adjust the daily long-term average to estimate a 30-year rate is available at the Treasury web site reported in footnote 13 of the release.

The H.15 site has links to the original September 17, 2001, release as well as to the revised releases for that date and for September 24.

Data for most of the interest rates reported in the H.15 release of September 17, 2001, were missing for September 11-13 because of inactive markets or delays in data processing arising from the disasters of September 11.

On September 25 the Treasury released the data that had been missing for September 13 regarding the constant maturity interest rates on Treasury securities and the secondary rates on bills. On October 1, 2001, the Federal Reserve issued a revised version of the H.15 release of September 17 to show the September 13 values of those series and the correspondingly updated values of the averages for the week ending September 14; also on October 1, 2001, the Federal Reserve issued a revised version of the September 24 release to show the new values of the averages for the week ending September 14.

On July 31, 2001, the Department of the Treasury began the weekly issuance of 4-week bills. On August 27, 2001, the Treasury stopped reporting secondary market yields for 1-year Treasury bills, the final issuance of which was on February 27, 2001.

Effective with the issue of September 4, 2001, the H.15 statistical release reflects these changes by reporting the secondary market rate for 4-week bills and by no longer reporting the secondary market rate for 1-year bills.

In addition, the H.15 now reports a 1-month constant maturity rate, which the Treasury began calculating when it introduced the 4-week bill.

Rates for fixed-rate payers in interest rate swaps, as collected under the auspices of the International Swaps and Derivatives Association, Inc., are being added. These swap rates are for maturities of 1, 2, 3, 4, 5, 7, 10, and 30 years.

No longer appearing on the release are auction highs for 3-month, 6-month, and 1-year Treasury bills. These figures continue to be available from the Treasury's website: http://www.publicdebt.treas.gov/of/ofrespr.htm. Also being dropped is the Treasury composite (an unweighted average of yields on all outstanding bonds neither due nor callable in less than 10 years).
