Treasury Inflation-Protected Securities are inflation-adjusted bonds issued by the U. S. Treasury. The principal is periodically adjusted for inflation, and the semi-annual fixed interest is paid on the adjusted principal. You pay tax annually on the interest payment. A drawback is that you also pay tax annually on the adjustment to the principal even though you don't receive the adjustment until you cash the bond.
