TreasuryDirect has made improvements to its website to enhance the user experience for buying I bonds. The changes include removing the virtual keyboard, introducing a one-time passcode sent to email, and reducing hold times for customer service calls [4ae2197a]. The surge in I bond buying last year caused strain on the system, prompting the Bureau of the Fiscal Service to implement these upgrades. The interest rates for I bonds have increased, making them an attractive investment. The composite rate for I bonds issued between May and October 2023 was 4.3%, and the Treasury Department recently announced that the composite rate for bonds issued between November 2023 and April 2024 is climbing up [4ae2197a]. TreasuryDirect has also simplified the process for adding a bank to an account and changing bank account information. However, customers still need to provide personal information and get it certified by a notary or certifying officer. While TreasuryDirect is the only place to buy U.S. savings bonds, other brokerage firms offer advantages for buying Treasury bills, Treasury notes, and Treasury Inflation-Protected Securities (TIPS). Overall, the changes made by TreasuryDirect have improved the user experience and attracted more interest in their other products [4ae2197a].
