| Accounting Policies [Abstract] | |
| Basis of Accounting | 2.1. Basis of Accounting For accounting purposes, GLDM is an investment company within the scope of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services—Investment Companies, and therefore applies the specialized accounting and reporting guidance therein. It is not registered as an investment company under the Investment Company Act of 1940, as amended. These financial statements present the financial condition, results of operations and cash flows of the Trust combined with its operating series and GLDM separately. For the periods presented, there were no balances or activity for the Trust and the footnotes accordingly relate to GLDM, unless stated otherwise. |
| Basis of Presentation | 2.2 Basis of Presentation The financial statements are presented for the Trust, as the SEC registrant, combined with GLDM and for GLDM individually. The debts, liabilities, obligations and expenses incurred, contracted for or otherwise existing with respect to GLDM are enforceable only against the assets of GLDM and not against the assets of the Trust generally or any other series that the Trust may establish. |
| Cash and Cash Equivalents | 2.3 Cash and Cash Equivalents Cash and cash equivalents, when outstanding, include highly liquid investments of sufficient credit quality with original maturity of three months or less. |
| Fair Value Measurement | 2.4. Fair Value Measurement U.S. GAAP defines fair value as the price a fund would receive to sell an asset or pay to transfer a liability in an orderly transaction between market participants at the measurement date. GLDM’s policy is to value its investments at fair value. Various inputs are used in determining the fair value of GLDM’s assets or liabilities. Inputs may be based on independent market data (“observable inputs”) or they may be internally developed (“unobservable inputs”). These inputs are categorized into a disclosure hierarchy consisting of three broad levels for financial reporting purposes. The level of a value determined for an asset or liability within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement in its entirety. The three levels of the fair value hierarchy are: Level 1 – Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability either directly or indirectly, including quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not considered to be active, inputs other than quoted prices that are observable for the asset or liability and inputs that are derived principally from or corroborated by observable market data by correlation or other means; and Level 3 – Inputs that are unobservable for the asset and liability, including a fund’s assumptions (if any) used in determining the fair value of investments. The following table summarizes GLDM’s investment at fair value: (Amounts in 000’s of US$) June 30, 2024 Level 1 Level 2 Level 3 Investment in Gold $ 7,395,810 $ - $ - Total $ 7,395,810 - - (Amounts in 000’s of US$) September 30, 2023 Level 1 Level 2 Level 3 Investment in Gold $ 5,779,814 $ - $ - Total $ 5,779,814 $ - $ - There were no transfers between Level 1 and other Levels for the nine months ended June 30, 2024 or for the year ended September 30, 2023. The Administrator values the gold held by GLDM on the basis of the price of an ounce of gold as determined by ICE Benchmark Administration Limited (the “IBA”), a benchmark administrator, which provides an independently administered auction process, as well as the overall administration and governance for the London Bullion Market Association (the “LBMA”). In determining the NAV of GLDM, the Administrator values the gold held on the basis of the price of an ounce of gold determined by the IBA 3:00 PM auction process (the “LBMA Gold Price PM”), which is an electronic auction. The auction runs twice daily at 10:30 AM and 3:00 PM London time. The Administrator calculates the NAV of GLDM on each day the NYSE Arca is open for regular trading, generally as of 12:00 PM New York time. If no LBMA Gold Price PM is made on a particular evaluation day or if the LBMA Gold Price PM has not been announced by 12:00 PM New York time on a particular evaluation day, the next most recent LBMA Gold Price AM or PM is used in the determination of the NAV of GLDM, unless the Administrator, in consultation with the Sponsor, determines that such price is inappropriate to use as the basis for such determination. |
| Custody of Gold | 2.5. Custody of Gold Gold is held by the Custodians on behalf of GLDM, 100% of which is allocated gold in the form of good delivery gold bars. A current list of all gold held by each Custodian, including any held with a subcustodian is available on the Sponsor’s website at www.spdrgoldshares.com. |
| Gold Receivable | 2.6. Gold Receivable Gold receivable represents the quantity of gold covered by contractually binding orders for the creation of Shares where the gold has not yet been transferred to GLDM’s account. Generally, ownership of the gold is transferred within one Jun-30, Sep-30, (Amounts in 000’s of US$) 2024 2023 Gold receivable $ - $ - |
| Gold Payable | 2.7. Gold Payable Gold payable represents the quantity of gold covered by contractually binding orders for the redemption of Shares where the gold has not yet been transferred out of GLDM’s account. Generally, ownership of the gold is transferred within one Jun-30, Sep-30, (Amounts in 000’s of US$) 2024 2023 Gold payable $ - $ 14,867 |
| Creations and Redemptions of Shares | 2.8. Creations and Redemptions of Shares GLDM creates and redeems Shares from time to time, but only in one or more Creation Units (a Creation Unit equals a block of 100,000 Shares). GLDM issues Shares in Creation Units to certain authorized participants (“Authorized Participants”) on an ongoing basis. The creation and redemption of Creation Units is only made in exchange for the amount of gold and any cash represented by the Creation Units being created or redeemed. This amount will be based on the combined net asset value of the number of Shares included in the Creation Units being created or redeemed determined on the day the order to create or redeem Creation Units is properly received. As the Shares are redeemable in Creation Units at the option of the Authorized Participants, GLDM has classified the Shares as Net Assets for financial reporting purposes. Changes in the Shares for the nine months ended June 30, 2024 and 2023 are as follows: Nine Months Nine Months Ended Ended (Amounts are in 000’s) Jun-30, 2024 Jun-30, 2023 Activity in Number of Shares Created and Redeemed: Creations 33,700 38,000 Redemptions (29,000 ) (15,300 ) Net Change in Number of Shares Created and Redeemed 4,700 22,700 Nine Months Nine Months Ended Ended (Amounts in 000’s of US$) Jun-30, 2024 Jun-30, 2023 Activity in Value of Shares Created and Redeemed: Creations $ 1,454,404 $ 1,396,621 Redemptions (1,249,711 ) (545,186 ) Net change in Value of Shares Created and Redeemed $ 204,693 $ 851,435 |
| Income and Expense | 2.9. Income and Expense (Amounts in 000 s of US$) The Administrator will, at the direction of the Sponsor, sell GLDM’s gold as necessary to pay its expenses. When selling gold to pay expenses, the Administrator will endeavor to sell the smallest amount of gold needed to pay expenses in order to minimize GLDM’s holdings of assets other than gold. Unless otherwise directed by the Sponsor, the Administrator will give a sell order and sell gold to the Custodians at the LBMA Gold Price PM following the sell order. A gain or loss is recognized based on the difference between the selling price and the average cost of the gold sold, and such amounts are reported as net realized gain/(loss) from investment in gold sold to pay Sponsor expenses on the Statement of Operations. GLDM’s net realized and change in unrealized gain/(loss) on investment in gold for the nine months ended June 30, 2024 of $1,430,999 is made up of a realized gain of $751 from the sale of gold to pay Sponsor fees, a realized gain of $214,919 from gold distributed for the redemption of shares, and a change in unrealized gain of $1,215,329 on investment in gold. GLDM’s net realized and change in unrealized gain/(loss) on investment in gold for the nine months ended June 30, 2023 of $677,598 is made up of a realized gain of $260 from the sale of gold to pay Sponsor fees, a realized gain of $17,736 from gold distributed for the redemption of shares, and a change in unrealized gain of $659,602 on investment in gold. |
| Income Taxes | 2.10. Income Taxes GLDM is classified as a “grantor trust” for U.S. federal income tax purposes. As a result, it is not subject to U.S. federal income tax. Instead, its income and expenses “flow through” to the shareholders, and the Administrator will report GLDM’s proceeds, income, deductions, gains and losses to the Internal Revenue Service on that basis. The Sponsor has evaluated whether there are uncertain tax positions that require financial statement recognition and has determined that no reserves for uncertain tax positions are required as of June 30, 2024. As of June 30, 2024, the 2023, 2022 and 2021 tax years remain open for examination. There were no examinations in progress at period end. |
