GraniteShares YieldBOOST 20Y Treasuries ETF (FIYY)

GraniteShares YieldBOOST 20Y Treasuries ETF (FIYY) is an actively managed option-income exchange-traded fund from GraniteShares, launched in 2026. It seeks to generate weekly income.

The fund sells put options on a separate exchange-traded fund that seeks three times the daily performance of the ICE U.S. Treasury 20+ Year Bond Index. Premiums collected from writing these puts provide the fund's income, while its assets are held mainly in short-term Treasury bills and cash as collateral.

The strategy gives indirect exposure to long-term U.S. Treasury bond prices through a leveraged fund, so it can incur losses when long-dated Treasuries fall significantly. Treasury bonds with very long maturities are highly sensitive to interest-rate moves, which the leveraged reference fund magnifies.
