Release Information

The Federal Reserve Board's "Selected interest rates (H.15)" contains daily interest rates for selected monetary policy, U.S. Treasury (secondary market), private money market and capital market instruments. Yields are in percent per annum. Weekly, monthly, and annual figures are averages of business days unless otherwise noted.

Definitions

Discount securities
Treasury Bills that are purchased at a price less than face value, to be redeemed for the face value at a specified later date. The rate of discount is approximately equal to the percentage below face value at which the security is purchased.
Coupon securities
Securities that pay periodic interest. They are purchased at a price very close to face value and at maturity are redeemed at face value. The rate of interest paid periodically, typically every six months, is referred to as its "coupon".
Equivalent bond yield (EBY)
Restates yields of discount securities on a basis that makes them comparable to the yield to maturity figures of coupon securities. For discount securities with six months or less to maturity, the EBY is the simple interest rate offered by the instrument, however for discount securities with more than six months to maturity, the EBY must account for the reinvestment of semiannual coupon payments.

Constant maturity series

Yields on Treasury nominal securities at “constant maturity” are interpolated by the U.S. Treasury from the daily yield curve for non-inflation-indexed Treasury securities. This curve, which relates the yield on a security to its time to maturity, is based on the closing market bid yields on actively traded Treasury securities in the over-the-counter market. These market yields are calculated from composites of quotations obtained by the Federal Reserve Bank of New York.

The constant maturity yield values are read from the yield curve at fixed maturities, currently 1, 3, and 6 months and 1, 2, 3, 5, 7, 10, 20, and 30 years. This method provides a yield for a 10-year maturity, for example, even if no outstanding security has exactly 10 years remaining to maturity.

Similarly, yields on inflation-indexed securities at “constant maturity” are interpolated from the daily yield curve for Treasury inflation protected securities in the over-the-counter market. The inflation-indexed constant maturity yields are read from this yield curve at fixed maturities, currently 5, 7, 10, and 20 years.

Periodicity, timeliness and gaps

The daily H.15 is published at 4:30 p.m. ET daily, with a one-business day lag. Federal holidays on Monday will (a) delay the report and (b) cause a gap in most series.

The weekly H.15 is published each Monday at 4:30, except when delayed by a Monday holiday. The reference date is the previous Friday.

The monthly H.15 is published on the first Monday of each month (hence, the lag varies between one and seven days), except when delayed by a holiday. Note that the human-readable report is posted at 2:30 p.m., but the FRB's bulk data system (DDP) is not updated until 4:30.

The FRB's reporting requires sufficient activity in the market. Gaps are not unusual in: rates on 2- and 3-month financial and nonfinancial commercial paper (IRCP(N,F)(2,3)MD.IUSA) and on 1-, 3- and 6-month CDs (IRCD(1,3,6)D.IUSA).

The 12-month Treasury bill on the secondary market (IRTB12MD.IUSA) was not reported from September 2001 to May 2008, but then resumed.

The 30-year Treasury constant maturity series (IRGT30YD.IUSA) was discontinued on February 18, 2002, and reintroduced on February 9, 2006. Moody's Analytics provides an estimated series (IRGTX30YD.IUSA) that fills the gap, using an adjustment factor published by the U.S. Treasury for this purpose.

How to use

Because the daily series have holiday-gaps, when converting to a lower frequency, please use the "ignore missing values" option in Data Buffet baskets and charts. Otherwise all periods containing holiday-gaps (i.e., ND values) will themselves show as ND.

The H.15 figures are not subject to revision.

The TED spread

The "TED Spread" is a popular indicator of credit risk. It is the price difference between three-month futures contracts for U.S. Treasuries and three-month contracts for Eurodollars having identical expiration months, or similar instruments. The series is computed daily by Moody's Analytics. An increase in the TED Spread indicates increasing risk of default, and investors will likely switch to safer investments; and vice-versa. Moody's Analytics updates the TED spread with the release of the H.15 Daily Interest rates.

The TED spread is the difference between the three-month USD Libor Rate and three-month T-bill rate, expressed in basis points. That is, ((IR%LIBOR3MUD.IUSA - IRTB3MD.IUSA) * 100)

Series altered by Data Buffet

The "three-month Nonfinancial Commercial Paper" rate (IRCPN3MM.IUSA) as reported by the Federal Reserve starts at January 1997. We have extended the series back to April 1971 by using the discontinued "three-month prime commercial paper - Average dealer offering rate, discount basis" series (IRCP3MM.IUSA).

Numbered footnotes

Generally quoted from the source:

1. The daily effective federal funds rate (IRFEDD.IUSA) is a weighted average of rates on brokered trades.

2. Weekly figures are averages of seven calendar days ending on Wednesday of the current week; monthly figures include each calendar day in the month.

3. Annualized using a 360-day year or bank interest.

4. Commercial paper, finance paper placed directly, and banker's acceptances are stated on a discount basis.

5. Interest rates on commercial paper are interpolated from data on certain commercial paper trades settled by The Depository Trust Company. The trades represent sales of commercial paper by dealers or direct issuers to investors (that is, the offer side). The 1-, 2-, and 3-month rates are equivalent to the 30-, 60-, and 90-day dates reported on the Board's Commercial Paper web page.

6. Rates on CDs on the secondary market are an average of dealer bid rates on nationally traded certificates of deposit.

7. Bid rates for Eurodollar deposits are collected around 9:30 a.m. Eastern time.

8. The bank prime loan rate is the rate posted by a majority of top 25 (by assets in domestic offices) insured U.S.-chartered commercial banks. Prime is one of several base rates used by banks to price short-term business loans.

9. The discount window primary credit rate is charged for discounts made and advances extended under the Federal Reserve's primary credit discount window program, which became effective January 9, 2003. This rate replaces that for adjustment credit, which was discontinued after January 8, 2003. For further information, see this 2002 FRB press release. The rate reported is that for the Federal Reserve Bank of New York. Historical series for the rate on adjustment credit as well as the rate on primary credit are available at the H.15 page.

10. Treasury constant maturities - nominal. Yields on actively traded non-inflation-indexed issues adjusted to constant maturities. The 30-year Treasury constant maturity series was discontinued on February 18, 2002, and reintroduced on February 9, 2006. From February 18, 2002, to February 9, 2006, the U.S. Treasury published a factor for adjusting the daily nominal 20-year constant maturity in order to estimate a 30-year nominal rate. The historical adjustment factor can be found at the U.S. Treasury web site and more methodology is here.
