We can only hope that the cpi drops to the fed’s targeted 2% as quickly as possible since I bonds only preserve capital. Although from my readings it is likely to drop more slowly over the next 1-3 years.

Historically speaking one article I was reading about the fed’s approach during the inflation period of the 70’s to 80’s was they eased off rate hikes too early only to raise them again. No real good option though since the article also said that once the fed actually breaks the economy their hand is forced to ease off the rate hikes.

Consider too that if inflation does drop to 2% in May your money doesn’t lose purchasing power except for the last 3 months of interest if cashed out before 5 years. Right now everything not matching an I bond is losing its purchasing power.
