Treasury Inflation-Indexed Securities (TIIS)
Refers to a broad range of U.S. Treasury securities that are inflation indexed. The most popular are the TIPS. The index for measuring the inflation rate is the non-seasonally adjusted U.S. City Average All Items Consumer Price Index for All Urban Consumers (CPI-U), published monthly by the Bureau of Labor Statistics (BLS).

Treasury Inflation-Protected Security
A U.S. Treasury security that protects the bondholder from inflation. Most Treasury securities, like most fixed dollar obligations, pay a fixed coupon rate periodically and mature at par. While this carries low risk, it exposes investors to the possibility that the inflation rate will outpace the interest rate represented on the coupon. In order to protect against this, a Treasury Inflation-Protected Security automatically increases its principal according to the inflation rate as tracked by the Consumer Price Index. Thus, while the coupon rate does not increase, the dollar amount paid does. Because TIPS are so safe, they offer a very low rate of return. See also: Real Return Bond.
