What Is the 30-Year Treasury?

The 30-Year Treasury is a U.S. Treasury debt obligation that has a maturity of 30 years. The 30-year Treasury used to be the bellwether U.S. bond but now most consider the 10-year Treasury to be the benchmark.

Understanding the 30-Year Treasury

The U.S. government borrows money from investors by issuing debt securities through its Treasury department. Debt instruments that can be purchased from the government include Treasury bills (T-bills), notes, and Treasury Inflation-Protected Securities (TIPS). T-bills are marketable securities issued for terms of less than a year, and Treasury notes are issued with maturities from two to 10 years.

TIPS are marketable securities whose principal is adjusted by changes in the Consumer Price Index (CPI). When there is inflation, the principal increases. When deflation sets in, the principal decreases. U.S. Treasury securities with longer-term maturities can be purchased as U.S. Savings bonds or Treasury bonds.

Special Considerations

Treasury bonds are long-term debt securities issued with a maturity of 20 years or 30 years from the issue date. These marketable securities pay interest semi-annually, or every six months until they mature. At maturity, the investor is paid the face value of the bond. The 30-year Treasury will generally pay a higher interest rate than shorter Treasuries to compensate for the additional risks inherent in the longer maturity. However, when compared to other bonds, Treasuries are relatively safe because they are backed by the U.S. government.

The price and interest rate of the 30-year Treasury bond is determined at an auction where it is set at either par, premium, or discount to par. If the yield to maturity (YTM) is greater than the interest rate, the price of the bond will be issued at a discount. If the YTM is equal to the interest rate, the price will be equal to par. Finally, if the YTM is less than the interest rate, the Treasury bond price will be sold at a premium to par. In a single auction, a bidder can buy up to $5 million in bonds by non-competitive bidding or up to 35% of the initial offering amount by competitive bidding. In addition, the bonds are sold in increments of $100 and the minimum purchase is $100.

30-Year Treasury vs. Savings Bonds

U.S. Savings bonds, specifically, Series EE Savings bonds, are non-marketable securities that earn interest for 30 years. Interest isn’t paid out periodically. Instead, interest accumulates, and the investor receives everything when they redeem the savings bond. The bond can be redeemed after one year, but if they are sold before five years from the purchase date, the investor will lose the last three months’ interest. For example, an investor who sells the Savings bond after 24 months will only receive interest for 21 months.

Because the U.S. is seen as a very low-risk borrower, many investors see 30-year Treasury interest rates as indicative of the state of the wider bond market. Normally, the interest rate decreases with greater demand for 30-year Treasury securities and rises with lower demand. The S&P U.S. Treasury Bond Current 30-Year Index is a one-security index comprising the most recently issued 30-year U.S. Treasury bond. It is a market value-weighted index that seeks to measure the performance of the Treasury bond market.

What Is a 10-Year Treasury Note?

The 10-year Treasury note is a debt obligation issued by the United States government with a maturity of 10 years upon initial issuance. A 10-year Treasury note pays interest at a fixed rate once every six months and pays the face value to the holder at maturity. The U.S. government partially funds itself by issuing 10-year Treasury notes.

Understanding 10-Year Treasury Notes

The U.S. government issues three different types of debt securities to fund its obligations: Treasury bills, Treasury notes, and Treasury bonds. Bills, bonds, and notes are distinguished by their length of maturity.

Treasury bills (T-bills) have the shortest maturities, with durations only up to a year. The Treasury offers T-bills with maturities of four, eight, 13, 26, and 52 weeks. Treasury notes have maturities ranging from a year to 10 years, while bonds are Treasury securities with maturities longer than 10 years.

Treasury notes and bonds pay interest at a fixed rate every six months to maturity, and are then redeemed at par value, meaning the Treasury repays the principal it borrowed.

In contrast, T-bills are issued at discounts to par and pay no coupon payments. The interest earned on T-bills is the difference between the face value repaid at maturity and the purchase price paid.

The 10-Year Note Yield as a Benchmark

The 10-year T-note is the most widely tracked government debt instrument in finance. Its yield is often used as a benchmark for other interest rates, like those on mortgages and corporate debt, though commercial interest rates do not track the 10-year yield exactly.

Below is a chart of the 10-year Treasury yield from March 2019 to March 2020. Over that span, the yield steadily declined with expectations that the Federal Reserve would maintain low interest rates or cut them further. In late February 2020, the decline in yield accelerated amid growing concerns about the economic effects of the COVID-19 pandemic. As the Fed ordered an emergency rate cut of 50 basis points in early March, the decline of the 10-year yield accelerated even further, with the yield dropping to 0.32%, a record low, before rebounding.

The Advantages of Investing in Treasury Notes

Fixed-income securities offer important portfolio diversification benefits, because their returns are not correlated with the performance of stocks.

Government debt and the 10-year Treasury note in particular is considered a relatively safe investment, so its price often (but not always) moves inversely to the trend of the major stock-market indices. In a recession, central banks tend to lower interest rates, which lowers the coupon rate on new Treasuries and, subsequently, makes older Treasury securities with higher coupon rates more desirable.

Another advantage of investing in 10-year Treasury notes and other federal government securities is that the coupon payments are exempt from state and local income taxes. However, they are still taxable at the federal level. The U.S. Treasury sells 10-year notes and those with shorter maturities, as well as T-bills and bonds, directly through the TreasuryDirect website via competitive or noncompetitive bidding, with a minimum purchase of $100 and in $100 increments. Treasury securities can also be purchased through a bank or broker.

Investors can choose to hold Treasury notes until maturity or sell them early in the secondary market. There is no minimum holding term. Although the Treasury issues new T-notes of shorter maturities every month, new 10-year notes are issued only in February, May, August, and November. In other months, the Treasury sells additional 10-year notes from the most recent issue in what is known as a re-opening. Re-opened notes have the same maturity date and coupon interest rate as the original issue, but a different issue date and a purchase price reflecting subsequent change in market interest rates.

All T-notes are issued electronically, meaning investors cannot obtain paper certificates. Series I Savings Bonds are the only Treasury securities currently issued in paper form, and they can only be bought in paper form with the proceeds of a tax refund.
