Segment Reporting [Abstract]
Number of operating segments	1
Segment Reporting, Expense Information Used by CODM, Description	An operating segment is defined in Topic 280 as a component of a public entity that engages in business activities from which it may recognize revenues and incur expenses, has operating results that are regularly reviewed by the public entity’s Chief Operating Decision Maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance, and has discrete financial information available. Selective members of the Executive Management Committee and other senior personnel of the Sponsor act as the Trust’s CODM. The Trust represents a single operating segment, as the CODM monitors the operating results of the Trust as a whole and the Trust’s long-term strategic asset allocation is pre-determined in accordance with the terms of its Trust agreement, based on a defined investment strategy which is executed by the Sponsor. The financial information in the form of the Trust’s assets, total returns, expense ratios and changes in net assets (i.e., changes in net assets resulting from operations, creations and redemptions), which are used by the CODM to assess the segment’s performance versus the Trust’s comparative benchmarks and to make resource allocation decisions for the Trust’s single segment, is consistent with that presented within the Trust’s financial statements. Segment assets are reflected on the accompanying statement of assets and liabilities as “total assets” and significant segment expenses are listed on the accompanying statement of operations.
