“Newly purchased I bonds will pay 4.26% annual interest through Oct. 31, up from the 4.03% yield offered through April 30, the U.S. Department of the Treasury announced last week.”

DISPUTED

The claim states I bonds will pay 4.26% through Oct 31. However, the provided web search evidence explicitly states that I bonds will pay 9.62% interest through October. This is a direct contradiction of the interest rate figure.
