US Treasury bonds

Treasury bonds pay a fixed interest rate on a semi-annual basis. This interest is exempt from state and local taxes. But it’s subject to federal income tax, according to TreasuryDirect.

Treasury bonds are government securities that have a 30-year term. They earn interest until maturity and the owner is also paid a par amount, or the principal, when the Treasury bond matures. They are marketable securities, so they can be sold before maturity – unlike U.S. savings bonds, which are non-marketable securities and are issued and registered to a specific owner and can’t be sold in the financial market.

Where can you buy Treasury bonds?

You can buy Treasury bonds directly and electronically from TreasuryDirect through non-competitive bidding. Non-competitive bidding means that you agree to accept the yield determined at auction and you’re guaranteed to receive both the amount and bond you want, according to TreasuryDirect.gov.

T-bonds are also bought through banks, brokers or dealers by either a competitive or non-competitive bid. In a competitive bid, you specify the yield that you’ll accept and you may or may not get the bond you want. If you do receive the Treasury bond, it may be less than the amount you requested.

Treasury bond auctions happen four times a year: in February, May, August and November. You must purchase at least $100 worth of Treasury bonds and they are sold in $100 increments. The maximum amount of Treasury bonds you may buy is up to $5 million during non-competitive bidding or up to 35 percent of the initial offering amount via competitive bidding.

What do Treasury bonds pay?

A 30-year U.S. Treasury Bond was paying around a 3.00 percent coupon in September 2018. That means the bond will pay $30.00 per year for every $1,000 in face value that you own. The semiannual coupon payments are half that, or $15.00 per $1,000. If you have a TreasuryDirect.gov account and use it to buy and hold U.S. Treasury securities, the coupon interest payments are made directly into your bank account.

Who should be looking at Treasury bonds?

Treasury bonds might be a good fit for someone who seeks safety, because Treasury securities are backed by the “full faith and credit” of the U.S. government, according to the U.S. Securities and Exchange Commission.

If you’re heavily invested in stocks, Treasury bonds may be an option to diversify your portfolio.

U.S. Treasury bonds are the de facto safe-haven investment for investors, says Greg McBride, CFA, Bankrate’s chief financial analyst. “So when the stock market goes down, you’ll often see investors flocking to the safety of Treasuries,” McBride says.

If it’s backed by the government, what’s the risk?

While they are relatively safe investments, the primary risk is that inflation will erode your returns over the years. When you get the bond’s face value back, it won’t have the same purchasing power that it did 30 years earlier.

If you’re looking at a time horizon of five years or less, CDs might be a better place for your money.

Treasury bonds in mid-2018 paid a little more than 3 percent. And the inflation over the next 30 years is likely to be around 3 percent annually, McBride says.

McBride says that in three decades, $1,000 will only have the buying power of $476, if inflation averages 2.5 percent over that period.

“So, this is not something that’s going to grow your buying power or your wealth in any meaningful way,” McBride says. “And you’ve got tremendous interest-rate risk if, for some reason, you need to sell prior to maturity.”

In that case, you’ll get more or less than the face value of the bonds.
