[NPORT-P] iShares Trust iShares USD Systematic Bond ETF SEC Filing

Rhea-AI Filing Summary

iShares Trust – iShares 20+ Year Treasury Bond BuyWrite Strategy ETF (symbol: USBF) filed its Form NPORT-P covering the period ended 30 April 2025.

Fund size and balance sheet: Total assets were reported at $1.0656 billion with total liabilities of $25.1 million, leaving net assets of $1.0404 billion. Liabilities therefore represent roughly 2.4 % of assets, indicating a low leverage profile.

Performance (last three months):

• Month 1 (most recent): +3.71 %
• Month 2: +0.61 %
• Month 3: -0.77 %

The fund produced positive total returns in two of the last three months, although results show a modest reversal in Month 3.

Derivatives activity: The Series employs equity-index options as part of its buy-write strategy. For Month 1 the portfolio realised $5.9 million of option gains but booked $26.4 million of unrealised losses, signalling mark-to-market volatility. The pattern reversed in Month 2 with $6.5 million of realised losses offset by $27.0 million of unrealised gains. Month 3 again showed realised gains ($7.5 million) and a smaller unrealised loss ($1.2 million).

Non-derivative investments: Realised losses persisted across all three months (-$0.6 million, -$1.1 million, -$8.2 million respectively). Unrealised moves were highly positive in Month 1 (+$55.2 million) but negative in Months 2 and 3 (-$15.6 million and -$11.1 million).

Risk & leverage: The filing shows no outstanding borrowings, preferred stock, delayed-delivery payables or cash equivalents, suggesting a conservative capital structure. Credit-spread risk metrics were not populated, implying that the <1-year rolling average of debt exposure is below the 25 % NAV threshold.

Other observations: • Securities-lending collateral details were not provided. • The fund indicates this is not its final NPORT-P filing. • LEI codes are supplied for both the trust and the Series. • Sales/redemption flow data were not included in the excerpt.

Insights

ETF Analyst

TL;DR: $1.04 B NAV, low liabilities & mixed option P/L; overall neutral impact.

The April 2025 NPORT-P shows the BuyWrite Treasury ETF maintaining >$1 billion in net assets with liabilities at only 2.4 % of assets—comfortably low for an options overlay vehicle. Monthly returns are mildly positive on a three-month look-back, but the swing between realised and unrealised option P/L underscores strategy-specific volatility. Absence of borrowings or preferreds limits balance-sheet risk, while unreported credit-spread metrics suggest minimal credit exposure. Missing flow data prevents assessment of investor demand. Net result: routine disclosure with no material surprises; neutral for valuation.

Risk Specialist

TL;DR: Volatile option marks yet conservative leverage keep risk contained.

From a risk lens, the vehicle shows zero structural leverage, no borrowing lines and no delayed-delivery payables. Option activity creates mark-to-market swings—Month 1 unrealised loss of $26 million vs Month 2 unrealised gain of $27 million—but these represent roughly 2.5 % of NAV each month, within normal variance for a buy-write mandate. The limited liabilities cushion the impact of such swings. Because credit-spread, borrowing and lending disclosures are minimal, systemic risk appears low. Impact to investors is neutral: performance volatility is expected, and solvency indicators remain strong.
