The iShares 20+ Year Treasury Bond BuyWrite Strategy ETF aims to replicate the performance of an index that implements a dual investment strategy. This strategy involves holding positions in the iShares 20+ Year Treasury Bond ETF while simultaneously generating income through the routine sale of one-month covered call options on those underlying assets.

iShares 20+ Year Treasury Bond BuyWrite Strat ETF (TLTW) will change its mandate and name to 'iShares TLT Premium Income+ ETF' in October 2026. TLTW will shift from a rate-hedged covered call strategy to a pure income extraction tool, mirroring TLT's total return profile. With the new structure, TLTW will no longer provide rate hedging, making its performance directly tied to long-term Treasury rates.

The Federal Reserve has taken its target rate from 4.5% to 3.75% over the past year, and reinvestment risk has arrived for anyone in money market funds.

Three little-known exchange-traded funds from BlackRock's iShares lineup distribute double-digit annual yields to shareholders monthly.

iShares 20+ Year Treasury Bond Buywrite Strategy ETF is a covered call long-term treasury ETF. The fund's covered calls boost its distribution yield to 11.2%, while capping upside potential. Downside remains unchanged, and for a long-term treasury ETF, rate downside is sky-high. Avoiding the fund while rate hikes are a possibility seems wise.

The iShares 20+ Year Treasury BuyWrite Strategy ETF is rated a strong buy, offering attractive yield and downside protection versus traditional long-duration Treasury ETFs. TLTW's covered call strategy enhances income and cushions against rising yields, outperforming AGG and BND on a total return basis since July 2024. Current long-term Treasury yields provide a much healthier margin of safety than in 2021, with breakeven yield now nearly four times higher.
