iShares Gold Trust SharesIAU

iShares Gold Trust (IAU) tells investors they own gold, but what they actually hold is a claim on a basket of 50,000 ounces whose size is recalculated every trading day using the LBMA Gold Price PM and the trust’s net asset value. The issuer’s marketing page glows with the promise of “physical gold exposure,” yet the fine print reveals the gold never leaves the vault; instead, the trustee adjusts the “Basket Gold Amount” when gold is sold, lost, or when fees accrue, turning ownership into a ledger entry underwritten by a series of agreements and a 1.50% expense ratio. The fund competes directly with other gold-backed products, traditional mining equities, and direct bullion purchases-none of which charge a daily vig for adjusting the filing trail.

The fund’s structure is straightforward but opaque: the trustee multiplies the NAV by 50,000 shares, divides by the LBMA PM price, and then subtracts accrued fees and expenses to determine the Basket Gold Amount for the next day. This daily mechanical grind means investors are not buying a static pile of metal but a rolling, trustee-managed instrument whose net exposure fluctuates with the trust’s costs as much as with the gold price. The filing even specifies that the gold bars must meet LBMA “good delivery” rules, a bureaucratic flourish that underscores the distance between the product’s marketing and the reality of a paper claim managed by a third-party trustee.

According to IAU’s latest 10-K (filed 27 February 2026), the trust competes with other financial vehicles, including traditional debt and equity securities issued by gold companies and other gold-backed or linked securities such as exchange-traded products, direct investments in gold, and other ETFs. The filing does not break out revenue or profit for IAU as a separate line item, because as a pass-through trust, its economics are embedded in the expense ratio and the daily NAV adjustments. The trustee is entitled to fees and reimbursement for out-of-pocket expenses in accordance with written agreements, a fact codified in the Fifth Amended and Restated Depositary Trust Agreement referenced in the trust’s SEC filings.

The fund’s expense ratio is 1.50%, a fixed levy that does not vary with gold’s price or the volume of shares traded. This ratio covers the trustee’s fees, storage, insurance, and other operating costs, and it is deducted from the trust’s gold holdings before the NAV is calculated each day. The SEC’s EDGAR database confirms the fund’s documents and amendments, including the trust agreement that governs how the basket is adjusted and how fees are deducted, but it does not publish real-time revenue or cash-flow figures for the trust itself. Investors therefore cannot disentangle how much of the 1.50% fee covers vault storage versus administrative overhead versus the issuer’s margin, because the trust’s structure is designed to pass through all costs to the NAV, not to disclose issuer-level margins.

On Nasdaq, IAU trades under the ticker IAU with intraday liquidity provided by market makers quoting on NYSE Arca, but the fund’s daily price is ultimately tethered to the LBMA PM gold price and the trust’s daily NAV calculation. The fund’s page on iShares’ official ETF centre confirms its mandate and top-line facts but offers no deeper disclosure on holdings concentration beyond the basket mechanics or issuer-level economics. The FINRA Fund Analyzer similarly treats IAU as a pass-through vehicle and reports only the expense ratio and risk disclosures, not the issuer’s internal economics or the gold’s physical custody details beyond what is stated in the SEC filings.

What changed this week: the fund’s NAV and basket size adjust daily, but no new filings, amendments, or earnings events were published in the SEC EDGAR feed for IAU during the past five trading days. The trust’s operating rhythm remains unchanged: each day the trustee recalculates the Basket Gold Amount, subtracts accrued fees and expenses, and publishes the new NAV. The only moving part is the gold price itself, which is reflected in the LBMA PM fix and the fund’s NAV, not in the issuer’s disclosed economics.
