I Bonds

As this WSJ article explains, you might do well to  move your cash from a bank account, where it’s probably earning about 0.02%, into an inflation-protected U.S. savings bond, which will yield 3.54% annualized. Buying an “I bond” is almost risk-free and delivers significant tax advantages. Economists say there’s no such thing as a free lunch, but I bonds offer a guarantee from the U.S. government that you can recover your original capital plus any increases in the official cost of living along the way. The only catch is that this isn’t an all-you-can-eat buffet: The maximum purchase is $10,000 per year per account holder (unless you elect to take your tax refund in the form of an I bond).
