Organization	9 Months Ended
	Jun. 30, 2017
Organization	1. Organization World Currency Gold Trust (the “Trust”) was organized as a Delaware statutory trust on August 27, 2014 and is governed by the Third Amended and Restated Agreement and Declaration of Trust (“Declaration of Trust”), dated as of January 6, 2017, between WGC USA Asset Management Company, LLC (the “Sponsor”) and the Delaware Trust Company (the “Trustee”). The Trust is authorized to issue an unlimited number of shares of beneficial interest (“Shares”). The beneficial interest in the Trust may be divided into one or more series. The Trust has established five separate series. The accompanying unaudited financial statements relate to the Trust and the SPDR® Long Dollar Gold Trust (the “Fund”), currently the only operational series of the Trust, which commenced operations in the first calendar quarter of 2017. The fiscal year end of both the Trust and the Fund is September 30. The investment objective of the Fund is to seek to track the performance of the Solactive GLD® Long USD Gold Index (the “Index”), less Fund expenses. The Index seeks to track the daily performance of a long position in physical gold, as represented by the London Bullion Market Association (“LBMA”) Gold Price AM, and a short position in a basket of specific non-U.S. currencies (i.e., a long U.S. dollar (“USD”) exposure versus the basket). Those non-U.S. currencies, which are weighted according to the Index, consist of the following: euro, Japanese yen, British pound sterling, Canadian dollar, Swedish krona, and Swiss franc (each, a “Reference Currency” and together the “Reference Currencies”). BNY Mellon Asset Servicing, a division of The Bank of New York Mellon (“BNYM”) is the Administrator and Transfer Agent of the Fund. BNYM also serves as the custodian of the Fund’s cash, if any. HSBC Bank plc (the “Custodian”) is responsible for custody of the Fund’s gold bullion. Merrill Lynch International is the Gold Delivery Provider to the Fund. State Street Global Markets, LLC is the marketing agent of the Fund. Solactive AG (“Index Provider”) has licensed the Index to the Sponsor for use with the Fund. The statement of financial condition and schedule of investments at June 30, 2017, the statements of operations and of cash flows for the three and nine months ended June 30, 2017 and the statement of changes in net assets for the nine months ended June 30, 2017 have been prepared on behalf of the Trust and the Fund without audit. In the opinion of management of the Sponsor, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows as of and for the three and nine months ended June 30, 2017 and for all periods presented have been made. The results of operations for the three and nine months ended June 30, 2017 are not necessarily indicative of the operating results for the full fiscal year. Capitalized terms used but not defined herein shall have the meaning as set forth in the Declaration of Trust. The Trust had no operations with respect to the Fund’s Shares prior to January 27, 2017 other than matters relating to its organization, the registration of the Fund’s Shares under the Securities Act of 1933, as amended, and the sale and issuance by the Fund on December 19, 2016 to WGC (US) Holdings, Inc. of 10 Shares of the Fund for an aggregate purchase price of $1,000.
