Vanguard Short-Term Inflation-Protected Securities Index Fund 

This exchange-traded fund seeks to mirror an index tracking U.S. Treasury inflation-protected securities (TIPS) with maturities of less than five years. It is designed to produce returns closely aligned with actual short-term inflation and aims to provide investors with a more stable investment profile compared to TIPS funds holding longer-dated assets. Due to its shorter duration, the fund typically incurs less real interest rate risk, though this often translates to lower overall returns when compared to longer-duration TIPS funds. Its portfolio consists of bonds guaranteed by the U.S. government, with their principal value adjusted twice a year according to inflation, thereby offering a safeguard against unforeseen increases in inflation.
