The U.S. Department of the Treasury has announced new Series I bond rates through April 2027.

From the article:

The new rate includes a variable portion of 4.08% based on inflation data, and a fixed portion of 1.40%. The fixed rate is up from 0.90% announced in April, and the highest since 2006.

Combined, the composite I bond rate is 5.51% after rounding, according to the Treasury.

Seems like inflation is bad of these seem like an attractive investment again.
