I bond rate: May 2001 - October 2001
Series I savings bond · issue period 2001-05
A Series I savings bond issued May 2001 - October 2001 earns a composite rate of 5.92% for its first six-month interest period. This is the 3.00% fixed rate — locked in for the life of the bond — combined with the 1.44% semiannual inflation rate set for this period. After the first six months the bond moves on to later inflation rates; only the fixed rate stays constant.

How the composite rate is computed
The Treasury composite-rate formula, applied to this period:
3.00% + (2 x 1.44%) + (3.00% x 1.44%) = 5.92%
The composite rate is floored at 0%, so a Series I bond never loses nominal value even when the inflation component is negative. The fixed rate of 3.00% applies for the bond’s full 30-year life. Try the composite-rate calculator to vary the inputs.

What is the fixed rate on a May 2001 - October 2001 I bond?
The fixed rate is 3.00%. The fixed rate never changes for the 30-year life of an I bond, so a bond bought in this period always carries a 3.00% fixed component on top of whatever inflation rate is in effect.
How is the 5.92% composite rate calculated?
Using the Treasury formula: 3.00% + (2 x 1.44%) + (3.00% x 1.44%) = 5.92%. The result is floored at 0%, so an I bond can never lose nominal value.
