While I bond rates change twice yearly based on inflation, you can still lock in 9.62% annual interest for six months — as long as you complete the purchase by Oct. 28. With the rate expected to drop to roughly 6.48% in November, there’s a brief window to secure higher interest for six months, assuming you haven’t exceeded the I bond purchase limits for 2022.
