GraniteShares YieldBOOST 20Y Treasuries ETF (FIYY)

On our desk, we are closely tracking FIYY's liquidity profile since its inception on May 5, 2026. With assets under management hovering around $737K and very low average daily volume, execution requires extreme caution. However, seeing Jane Street open a new position worth approximately $709K in Q2 2026 gives us a clear signal that market makers are actively facilitating liquidity for this derivative income structure.

Looking at the fund's expense ratio of 1.07%, which includes a management fee of 0.99%, I find the overhead quite steep for an ETF tied to long-duration U.S. Treasury exposure. Combined with the fact that its July 2026 distribution statement pursuant to Section 19(a) revealed that roughly 79.45% of the payout came from a return of capital, long-term investors need to carefully evaluate the tax and capital erosion implications.

When analyzing the technical mechanics of FIYY for portfolio construction, you must recognize that it doesn't just hold 20+ year bonds. Instead, it utilizes an options-based YieldBOOST strategy primarily by selling put options on leveraged ETFs tracking the 3x Long 20Y+ Treasuries Daily ETF. This introduces unique path-dependent volatility and gamma risks that standard bond fund analysts often overlook.

From a risk management standpoint, the fund's weekly targeted distribution frequency sounds attractive for income-seeking portfolios, but the 30-day SEC yield sitting at 0.92% as of mid-2026 tells a more conservative underlying story. We are advising clients to monitor how the fund sustains its payouts without eroding its net asset value, which currently sits around $24.57.

Watching the market reception on FIYY since its Nasdaq listing, retail engagement remains extremely quiet with minimal daily share turnover. The lack of an underlying tracked index means it relies entirely on active management decisions regarding its derivative overlay, making transparency into daily option strikes and expirations vital for our desk's risk models.
