The history of U.S. Treasury interest rates depicts the yield on a security to its time to maturity, with historical information available on the Treasury Direct website. Visitors can modify the data accordingly to view the historical treasury rate for a particular period.
The U.S. Department of the Treasury website offers interactive charts and lists showing historical interest rates. The lists contain information on the date and the associated interest rates, which vary based on the time to maturity. For instance, some of the data lists the long-term composite rate for a security with a 10-year maturity period. Visitors can select the type of interest rate to view and the appropriate time period. The descriptions below the table specify the factors that impacted the interest rates for a particular period.
The U.S. Department of the Treasury website also lists information related to daily treasury yield curve rates, daily treasury real yield curve rates, daily treasury bill rates and daily treasury long-term rates. These rates vary based on the time to maturity and the closing market bids on actively traded securities. Statistical information on various type of treasury securities, including Treasury Inflation Protected Securities, is also available. The resource center also lists press releases and other information associated with treasury rates.
