Investors can take a look at a number of TIPS-related ETFs to gain exposure to Treasury inflation-protected securities. For instance, the iShares TIPS Bond ETF (NYSEArca: TIP) tracks a group of U.S. TIPS from the Barclays U.S. Treasury Inflation Protected Securities Index (Series-L). The ETF comes with an effective duration of 7.69 years and a 0.20% expense ratio.

The SPDR Barclays TIPS ETF (NYSEArca: IPE), which tracks the Barclays U.S. Government Inflation-Linked Bond Index, is a slightly cheaper alternative, with a 0.15% expense ratio and a lower 5.97 year duration. However, IPHE is less actively traded, showing an average daily volume of about 34,000 shares, according to Morningstar.

The Schwab U.S. TIPS (NYSEArca: SCHP), which also tracks the same index as TIP, is the cheapest option in the category, with a 0.07% expense ratio, and comes with a 7.7 year effective duration.
