BlackRock has launched five iShares ETFs that invest in U.S. Treasury Inflation-Protected Securities (TIPS) of varying maturities. Investors can use the TIPS funds to seek inflation protection, build a bond ladder, and manage interest rate risk. “BlackRock has a strong suite of target maturity ETFs to help advisors and clients manage their duration,” said VettaFi’s head of research Todd Rosenbluth.
