The iShares 1–3 Year Treasury Bond ETF (SHY) is an exchange-traded fund that seeks to track the performance of an index composed of U.S. Treasury securities, providing exposure to the short-term fixed income segment. The ETF is managed by BlackRock and trades under the ticker SHY on NYSE Arca.
Classified as a U.S. short-term fixed income ETF, SHY aims to reflect, before fees and expenses, the aggregated performance of the U.S. Treasury securities that comprise its benchmark index.
To achieve this objective, the fund employs a passive management strategy, maintaining a portfolio that seeks to replicate the composition and weighting of the index.
SHY’s benchmark index consists of U.S. Treasuries weighted by float-adjusted market capitalization, with periodic updates to add new issues and remove securities approaching maturity.
Composition and Exposure Profile
SHY provides exposure to the short-term U.S. government bond market, with a focus on highly liquid, low-credit-risk instruments, including U.S. Treasury securities with maturities between 1 and 3 years.
This structure gives the ETF a low-volatility profile, suitable for investors prioritizing capital preservation and stable income in the short term.
Structure and costs
Shares of SHY are traded on the secondary market, while creation and redemption of shares are carried out by authorized participants, a mechanism that helps keep the ETF’s market price close to its net asset value (NAV).
The fund carries a low expense ratio, typical of passively managed short-term fixed-income ETFs, and does not charge a performance fee. SHY makes periodic income distributions, derived from interest payments on the U.S. Treasury securities held in its portfolio. The ETF has a single share class and trades exclusively under the ticker SHY.
History and evolution of the ETF
The iShares 1–3 Year Treasury Bond ETF was launched in 2002, amid growing demand for efficient access to the U.S. short-term fixed income market.
Since its inception, SHY has been used by institutional and individual investors as a tool for capital preservation and cash management, particularly during periods of volatility or economic uncertainty.
Between 2020 and 2024, the ETF tracked expectations for short-term interest rates and adjustments in monetary policy, maintaining high liquidity and broad use as a risk-management and return tool in short-term fixed income.
