While you may not be a huge fan of the issuer — that would be the U.S. Treasury, a department of the U.S. government — you’re not going to find many safer sources of fixed income. After all, they have the power to create money.
These bonds are not new, but they’re newly enticing. You see, the interest rate is tied to one of the U.S. Governments measure of inflation, the CPI-U, and that’s been going nowhere but up in recent months.
In summary, it’s a combination of a fixed rate (currently 0%) and a variable rate, each of which are updated every six months in November and May. The fixed rate has been under 1% since May of 2008 and has not been above 2% since 2001.
