This instrument seems to be asleep at the wheel. With inflation weighing in at about 8%, and TIPS bonds paying about 2⅓%. I did the calcuations, and the numbers aren't adding up... maybe one of you can check my math. Can anyone explain why TIPS bonds aren't covering the inflation rate, when that's their raison d'être; their purpose for existing? 1. https://www.treasurydirect.gov/indi..., or,original principal, whichever is greater.
