This is an average, not today's rate. This is the average across savings bonds already outstanding, blending decades of issues — not what a bond bought today would pay. Rates for new Series I and Series EE bonds are set twice a year and published by TreasuryDirect. For a market-based read on inflation protection, see TIPS real yields.
