In recent years, bond investors have been reaping the benefits of rising interest rates. Bonds are now offering higher yields than ever before, making the bond market more appealing than ever. As a result, investors are on the hunt for the best broker for bonds, and some new upstart brokers are even allowing investors to invest in partial bonds, enabling them to get started with virtually any amount of money.

Why Bonds Are a Great Option for Retirement Portfolios

Bonds are not as popular as stocks among individual investors because their potential return is generally lower. However, a bond promises a specific payout over its lifetime and is less volatile than a stock. These qualities make it an attractive option for retirement portfolios. While the best brokers for stock trading have slashed their commissions to zero, trading bonds may still cost a small commission.For example, Charles Schwab charges no commission on U.S. Treasurys and only $1 per bond for other types of bonds, with a $10 minimum. Fidelity also allows investors to buy U.S. Treasurys through auctions or on the secondary market for no commission. Other dollar-denominated bonds have a $1 per bond price with no stated minimum.

Charles Schwab: A Low-Cost Option for Bond Trading

Charles Schwab is an attractive place to trade bonds due to its low commissions. The broker charges no commission on U.S. Treasurys and only $1 per bond for corporate and municipal bonds, with a $10 minimum. In addition to bonds, Schwab offers access to a variety of other tradable securities such as stocks, ETFs, mutual funds, options, and more. This makes it one of the best places to build an investment portfolio.For instance, when investing in U.S. Treasurys, there is no commission. On other types of bonds, the commission is just $1 per bond, which is relatively low compared to other brokers.

Fidelity Investments: A Reliable Choice for Bond Investors

Investors can buy corporate or Treasury bonds with as little as $100. The broker charges $0.10 to $0.25 for every $100 face value in Treasurys and $0.35 to $0.50 for every $100 in face value of corporate bonds.Clients can also open a bond account with a $1,000 minimum investment.

Corporates cost 0.1 percent of face value for the first $10,000, with a $1 minimum, and amounts above $10,000 are charged at just one-quarter the base rate.Interactive Brokers also provides access to markets around the world and a broad range of tradable securities, including cryptocurrencies in cooperation with a business partner.

Terms of less than one year are charged 0.07 percent, those from one to three years are charged 0.4 percent, and those longer than three years are charged 0.7 percent.
