Treasury inflation-protected securities

Definition

Treasury inflation-protected securities (TIPS) are a type of investment issued by the U.S. Department of the Treasury. They are designed to provide protection against inflation by adjusting their principal value based on changes in the consumer price index (CPI). 

What are Treasury inflation-protected securities?

TIPS offer investors a way to protect the purchasing power of their investment over time, making them particularly attractive during periods of rising prices.

Unlike traditional fixed-income securities, TIPS provide investors with inflation protection. The principal value of TIPS adjusts periodically based on changes in the CPI. As inflation rises, the principal value of TIPS increases, providing investors with a hedge against purchasing power degradation.

TIPS pay interest semiannually, but the interest payments are calculated based on the adjusted principal value of the security. This means that as the principal value increases with inflation, the interest payments also increase. As a result, investors receive a higher income stream that reflects changes in the cost of living.

TIPS are issued by the U.S. government, making them backed by the full faith and credit of the United States. They are considered one of the safest investments available, as they are backed by the government’s ability to tax and print currency. This makes TIPS particularly attractive to investors seeking a low-risk investment option.

While TIPS interest payments are subject to federal income tax, the inflation adjustments to the principal value are not taxed until the securities are sold or mature. This tax treatment can provide investors with additional tax advantages, particularly in periods of high inflation.

Example of Treasury inflation-protected securities

An example of Treasury inflation-protected securities is when an investor purchases $10,000 worth of TIPS with a fixed interest rate of 2% and an inflation adjustment based on the consumer price index. If inflation increases by 3% over the next year, the principal value of the TIPS would adjust upward by 3%, resulting in a new principal value of $10,300. Additionally, the interest payment would be calculated based on the adjusted principal, providing the investor with a higher income stream that reflects the impact of inflation.
