Are I-bonds a good investment now? Here's what to know.

Another investment savers may want to consider that has benefited from the upward drift in rates is Series I savings bonds, known as "I-bonds." The U.S. Department of Treasury raised the rate on I-bonds last week to 5.27%, up from 4.35% in January.
