Disclosure Text Block [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	NOTE 1. BASIS OF PRESENTATION U.S. Global Investors, Inc. (the “Company” or “U.S. Global”) has prepared the consolidated financial statements pursuant to accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (“SEC”) that permit reduced disclosure for interim periods. The financial information included herein reflects all adjustments (consisting solely of normal recurring adjustments), which are, in management’s opinion, necessary for a fair presentation of results for the interim periods presented. The Company has consistently followed the accounting policies set forth in the notes to the consolidated financial statements in the Company’s Form 10-K for the fiscal year ended June 30, 2017, except for the adoption of new accounting pronouncements discussed below. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, U.S. Global Brokerage, Inc., U.S. Global Investors (Bermuda) Limited, U.S. Global Investors (Canada) Limited (“USCAN”), and U.S. Global Indices, LLC, and its 65 percent interest in Galileo Global Equity Advisor Inc. (“Galileo”). U.S. Global Brokerage, Inc. ceased operations in December 2015. Galileo is consolidated with the operations of the Company. The non-controlling interest in this subsidiary is included in “non-controlling interest in subsidiary” in the equity section of the Consolidated Balance Sheets. Frank Holmes, CEO, and Susan McGee, President and General Counsel, serve as directors of Galileo. There are two primary consolidation models in U.S. GAAP, the variable interest entity (“VIE”) and voting interest entity models. The Company’s evaluation for consolidation includes whether entities in which it has an interest or from which it receives fees are VIEs and whether the Company is the primary beneficiary of any VIEs identified in its analysis. A VIE is an entity in which either (a) the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or (b) the group of holders of the equity investment at risk lack certain characteristics of a controlling financial interest. The primary beneficiary is the entity that has the obligation to absorb a majority of the expected losses or the right to receive the majority of the residual returns and consolidates the VIE on the basis of having a controlling financial interest. The Company holds variable interests in, but is not deemed to be the primary beneficiary of, certain funds it advises, specifically, certain funds in U.S. Global Investors Funds (“USGIF” or the “Funds”) and one of the offshore funds. The Company’s interests in these VIEs consist of the Company’s direct ownership therein and any fees earned but uncollected. See further information about these funds in Notes 2 and 3. In the ordinary course of business, the Company may choose to waive certain fees or assume operating expenses of the funds it advises for competitive, regulatory or contractual reasons (see Note 3 for information regarding fee waivers). The Company has not provided financial support to any of these entities outside the ordinary course of business. The Company’s risk of loss with respect to these VIEs is limited to the carrying value of its investments in, and fees receivable from, the entities. The Company does not consolidate these VIEs because it is not the primary beneficiary. The Company’s total exposure to unconsolidated VIEs, consisting of the carrying value of investment securities and receivables for fees, was $9.1 million at September 30, 2017, and $11.3 million at June 30, 2017. The Company holds a variable interest in a fund advised by Galileo, but this fund does not qualify as a VIE. Since the fund is not a VIE, the Company evaluated if it should consolidate the fund under the voting interest entity model. Under the voting interest model, for legal entities other than partnerships, the usual condition for control is ownership, directly or indirectly, of more than 50 percent of the outstanding voting shares over an entity. The Company does not have control of the fund and, therefore, does not consolidate the fund. However, the Company owns approximately 30 percent of the fund, and is considered to have the ability to exercise significant influence. Thus, the investment is accounted for under the equity method of accounting. See further information about this investment in Note 2. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts have been reclassified for comparative purposes. The results of operations for the three months ended September 30, 2017, are not necessarily indicative of the results to be expected for the entire year. The unaudited interim financial information in these condensed financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s annual report.

Disclosure Text Block Supplement [Abstract]
Investments and Other Noncurrent Assets [Text Block]	NOTE 2. INVESTMENTS As of September 30, 2017, the Company held investments with a fair value of approximately $22.5 million and a cost basis of approximately $13.1 million. The fair value of these investments is approximately 62.7 percent of the Company’s total assets. In addition, the Company held other investments of $2.1 million accounted for under the cost method of accounting and an investment of $2.0 million accounted for under the equity method of accounting. Investments in securities classified as trading are reflected as current assets on the Consolidated Balance Sheets at their fair value. Unrealized holding gains and losses on trading securities are included in earnings in the Consolidated Statements of Operations. Investments in securities classified as available-for-sale, which may not be readily marketable, are reflected as non-current assets on the Consolidated Balance Sheets at their fair value. Unrealized holding gains and losses on available-for-sale securities are excluded from earnings and reported in other comprehensive income as a separate component of shareholders’ equity until realized. Other investments consist of equity investments in entities over which the Company is unable to exercise significant influence and which do not have readily determinable fair values. These investments are accounted for under the cost method of accounting and evaluated periodically for impairment. The Company considers many factors in determining impairment, including the severity and duration of the decline in value below cost, the Company’s interest and ability to hold the security for a period of time sufficient for an anticipated recovery in value, and the financial condition and specific events related to the issuer. When an impairment of a security is determined to be other than temporary, the impairment is recognized as a loss in the Company’s earnings. Investments classified as equity method consist of investments in companies in which the Company is able to exercise significant influence but not control. Under the equity method of accounting, the investment is initially recorded at cost, then the Company’s proportional share of investee’s underlying net income or loss is recorded as a component of “other income” with a corresponding increase or decrease to the carrying value of the investment. Distributions received from the investee reduce the Company’s carrying value of the investment. These investments are evaluated for impairment if events or circumstances arise that indicate that the carrying amount of such assets may not be recoverable. The Company records security transactions on trade date. Realized gains (losses) from security transactions are calculated on the first-in/first-out cost basis, unless otherwise identifiable, and are recorded in earnings on the date of sale. The following details the components of the Company’s investments recorded at fair value as of September 30, 2017, and June 30, 2017.

On September 30, 2017, the Company had $8.9 million and $55,000 at fair value invested in USGIF and an offshore fund the Company advises, respectively. These amounts were included in the Consolidated Balance Sheets and the table above as “trading securities” and “available-for-sale securities.” Investment income can be volatile and varies depending on market fluctuations, the Company’s ability to participate in investment opportunities, and timing of transactions. The Company expects that gains and losses will continue to fluctuate in the future. Investment income (loss) from the Company’s investments includes: • realized gains and losses on sales of securities; • unrealized gains and losses on trading securities; • realized foreign currency gains and losses; • other-than-temporary impairments on available-for-sale securities; • other-than-temporary impairments on held-at-cost securities; and • dividend and interest income. The following summarizes investment income (loss) reflected in earnings for the periods discussed: (dollars in thousands) Three Months Ended September 30, Investment Income 2017 2016 Realized gains on sales of available-for-sale securities $ 7 $ - Realized losses on sales of trading securities (654 ) - Unrealized gains on trading securities 686 99 Realized foreign currency gains (losses) (22 ) 2 Other-than-temporary declines in available-for-sale securities - (16 ) Dividend and interest income 192 168 Total Investment Income $ 209 $ 253 Included in investment income were other-than temporary declines in value on available-for-sale securities of approximately $16,000 for the three months ended September 30, 2016. There were no impairment losses for the three months ended September 30, 2017. During the three months ended September 30, 2016, impairment losses resulted from fair values of securities being lower than book value, and two securities with a combined cost basis of $98,000 were written down to a combined fair value of $82,000. In making these determinations, the Company considered the length of time and extent to which the fair value has been less than cost basis, financial condition and prospects of the issuers and the Company’s ability to hold the investment until recovery. Unrealized Losses The following tables show the gross unrealized losses and fair values of available-for-sale investment securities with unrealized losses aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position.

Since valuations are based on quoted prices that are readily and regularly available in an active market, value of these products does not entail a significant degree of judgment. Level 2 – Valuations based on quoted prices in markets for which not all significant inputs are observable, directly or indirectly. Corporate debt securities valued in accordance with the evaluated price supplied by an independent service are categorized as Level 2 in the hierarchy. Other securities categorized as Level 2 include securities valued at the mean between the last reported bid and ask quotation and securities valued with an adjustment to the quoted price due to restrictions. Level 3 – Valuations based on inputs that are unobservable and significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the financial instrument. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with the investing in those securities. Because of the inherent uncertainties of valuation, the values reflected may materially differ from the values received upon actual sale of those investments. For actively traded securities, the Company values investments using the closing price of the securities on the exchange or market on which the securities principally trade. If the security is not traded on the last business day of the quarter, it is generally valued at the mean between the last bid and ask quotation. The fair value of a security that has a restriction is based on the quoted price for an otherwise identical unrestricted instrument that trades in a public market, adjusted for the estimated effect of the restriction. Mutual funds, which include open- and closed-end funds, exchange-traded funds, and offshore funds, are valued at net asset value or closing price, as applicable. Certain corporate debt securities not traded on an exchange may be valued by an independent pricing service using an evaluated quote based on such factors as institutional-size trading in similar groups of securities, yield, quality maturity, coupon rate, type of issuance and individual trading characteristics and other market data. As part of its independent price verification process, the Company periodically reviews the fair value provided by the pricing service using information such as transactions in these investments, broker quotes, market transactions in comparable investments, general market conditions and the issuer’s financial condition. Certain debt securities may be valued based on review of similarly structured issuances in similar jurisdictions, when possible, or based on other traded debt securities issued by the issuer. The Company also takes into consideration numerous other factors that could affect valuation such as overall market conditions, liquidity of the security and bond structure. Securities for which market quotations are not readily available are valued at their fair value as determined by the portfolio management team. The portfolio management team includes representatives from the investment, accounting and legal/compliance departments. The portfolio management team meets periodically to consider a number of factors in determining a security’s fair value, including the security’s trading volume, market values of similar class issuances, investment personnel’s judgment regarding the market experience of the issuer, financial status of the issuer, the issuer’s management, and back testing, as appropriate. The fair values may differ from what may have been used had a broader market for these securities existed. The portfolio management team reviews inputs and assumptions and reports material items to the board of directors. The following presents fair value measurements, as of September 30, 2017, and June 30, 2017, for the major categories of U.S. Global’s investments measured at fair value on a recurring basis: September 30, 2017 Quoted Prices Significant Other Inputs Significant Unobservable Inputs (dollars in thousands) (Level 1) (Level 2) (Level 3) Total Trading securities Mutual funds - Fixed income $ 7,067 $ - $ - $ 7,067 Mutual funds - Domestic equity 389 - - 389 Other - - - - Offshore fund investment measured at net asset value 1 55 Total trading securities 7,456 - - 7,511 Available-for-sale securities Common stock - Domestic 118 - - 118 Common stock - International 200 11,395 - 11,595 Corporate debt 1,606 - - 1,606 Mutual funds - Fixed income 1,148 - - 1,148 Mutual funds - Domestic equity 410 - - 410 Other 67 - - 67 Total available-for-sale securities 3,549 11,395 - 14,944 Total securities at fair value $ 11,005 $ 11,395 $ - $ 22,455 June 30, 2017 Quoted Prices Significant Other Inputs Significant Unobservable Inputs (dollars in thousands) (Level 1) (Level 2) (Level 3) Total Trading securities Mutual funds - Fixed income $ 8,927 $ - $ - $ 8,927 Mutual funds - Domestic equity 378 - - 378 Other - - - - Offshore fund investment measured at net asset value 1 415 Total trading securities 9,305 - - 9,720 Available-for-sale securities Common stock - Domestic 113 - - 113 Common stock - International 203 - - 203 Corporate debt 1,469 - - 1,469 Mutual funds - Fixed income 1,144 - - 1,144 Mutual funds - Domestic equity 406 - - 406 Other 66 - - 66 Total available-for-sale securities 3,401 - - 3,401 Total securities at fair value $ 12,706 $ - $ - $ 13,121 1 In accordance with Subtopic 820-10, certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Consolidated Balance Sheets. As of September 30, 2017, approximately 49 percent of the Company’s financial assets measured at fair value were classified as Level 1 and 51 percent of the Company’s financial assets measured at fair value were classified as Level 2. As of June 30, 2017, 100 percent of the Company’s financial assets were classified in the fair value hierarchy as Level 1. The Company recognizes transfers between levels at the end of each quarter. During the quarter ended September 30, 2017, the Company invested in common shares of HIVE Blockchain Technologies Ltd. (“HIVE”), a company that is headquartered and traded in Canada with cryptocurrency operations in Iceland. The shares held by the Company are restricted for resale until February 2018 and are also subject to Canadian insider regulations. The investment, classified as available-for-sale, was valued at approximately $11.4 million at September 30, 2017, based on the quoted market price adjusted for the restriction on resale and is classified as Level 2 in the fair value hierarchy. A unit trust investment fund managed by Galileo, described below under Investment Classified as Equity Method, The Company has an investment in an affiliated offshore fund, classified as trading, which invests in companies in the energy and natural resources sectors. The fair value of this investment has been estimated based on the net asset value per share at $55,000 and $415,000 as of September 30, 2017, and June 30, 2017, respectively. This offshore fund is in the process of liquidating, and partial liquidation proceeds were received in the quarter ended September 30, 2017. It is anticipated that the offshore fund will complete its liquidation in the second quarter of fiscal year 2018. Investment Classified as Equity Method During the quarter ended September 30, 2017, the Company, through USCAN, invested in the Galileo Partners Fund, a Canadian unit trust investment fund managed by Galileo. This fund’s sole investment is in HIVE, the same company described above that the Company has also invested in directly; the fund held 6.7 million common shares as of September 30, 2017. The Company owns approximately 30 percent of Galileo Partners Fund, and is considered to have the ability to exercise significant influence. Thus, the investment is accounted for under the equity method of accounting. Under the equity method, the Company’s proportional share of the fund’s net income or loss, which primarily consists of realized and unrealized gains and losses on investments offset by fund expenses, is recognized in the Company’s earnings. Included in other income for the three months ending September 30, 2017, is $1.5 million of equity method income of Galileo Partners Fund. Frank Holmes also directly held an investment in the fund as of September 30, 2017.

The Company recorded base advisory fees from USGIF totaling $1.1 million and $1.5 million, respectively, for the three months ended September 30, 2017, and 2016, respectively. The advisory agreement for the equity funds within USGIF provides for a base advisory fee that is adjusted upwards or downwards by 0.25 percent when there is a performance difference of 5 percent or more between a fund’s performance and that of its designated benchmark index over the prior rolling 12 months.

The aggregate fees waived and expenses borne by the Company for USGIF for the three months ended September 30, 2017, were $232,000 compared with $234,000 for the corresponding period in the prior fiscal year. Management cannot predict the impact of future waivers due the number of variables and the range of potential outcomes. The Company receives administrative service fees from USGIF based on the average daily net assets at an annual rate 0.05 percent per investor class and 0.04 percent per institutional class of each fund. As of September 30, 2017, the Company had $437,000 in receivables from fund clients, of which $318,000 was from USGIF.

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	NOTE 7. EARNINGS PER SHARE The basic earnings per share (“EPS”) calculation excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution of EPS that could occur if options to issue common stock were exercised. The following table sets forth the computation for basic and diluted EPS: Three Months Ended September 30, (dollars in thousands, except per share data) 2017 2016 Net Income $ 1,236 $ 264 Less: Net Income (Loss) Attributable to Non-Controlling Interest (34 ) 1 Net Income Attributable to U.S. Global Investors, Inc. $ 1,270 $ 263 Weighted average number of outstanding shares Basic 15,182,651 15,240,957 Effect of dilutive securities Employee stock options - - Diluted 15,182,651 15,240,957 Earnings Per Share Attributable to U.S. Global Investors, Inc.

During the three months ended September 30, 2017, and 2016, the Company repurchased class A shares on the open market. Upon repurchase, these shares are classified as treasury shares and are deducted from outstanding shares in the earnings per share calculation.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	NOTE 8. INCOME TAXES The Company and its non-Canadian subsidiaries file a consolidated U.S. federal income tax return. USCAN and Galileo file separate tax returns in Canada. Provisions for income taxes include deferred taxes for temporary differences in the bases of assets and liabilities for financial and tax purposes, resulting from the use of the liability method of accounting for income taxes. The Company has not recognized deferred income taxes on undistributed earnings of Galileo since such earnings are considered to be reinvested indefinitely. For federal income tax purposes at September 30, 2017, the Company has charitable contribution carryovers totaling approximately $149,000, with $68,000 expiring in fiscal year 2018, $34,000 expiring in fiscal year 2019, $19,000 expiring in fiscal year 2020, $5,000 expiring in fiscal year 2021, $21,000 expiring in fiscal year 2022, and $2,000 expiring in fiscal year 2023. The Company has federal net operating loss carryovers of $4.8 million with $2.0 million expiring in fiscal year 2035, $2.7 million expiring in fiscal year 2036, and $71,000 expiring in fiscal year 2038.

If certain changes in the Company’s ownership should occur, there could be an annual limitation on the amount of net operating loss carryovers that could be utilized. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax amount will not be realized. At September 30, 2017, and June 30, 2017, a valuation allowance of $3.3 million and $3.3 million, respectively, was included net operating loss carryovers, other carryovers and book/tax differences in the balance sheet.

Commitments and Contingencies Disclosure [Text Block]	NOTE 11. CONTINGENCIES AND COMMITMENTS The Company continuously reviews all investor, employee and vendor complaints, and pending or threatened litigation. The likelihood that a loss contingency exists is evaluated through consultation with legal counsel, and a loss contingency is recorded if probable and reasonably estimable. During the normal course of business, the Company may be subject to claims, legal proceedings, and other contingencies. These matters are subject to various uncertainties, and it is possible that some of these matters may be resolved unfavorably. The Company establishes accruals for matters for which the outcome is probable and can be reasonably estimated. Management believes that any liability in excess of these accruals upon the ultimate resolution of these matters will not have a material adverse effect on the consolidated financial statements of the Company. The Board has authorized a monthly dividend of $0.0025 per share through December 2017, at which time it will be considered for continuation by the Board. Payment of cash dividends is within the discretion of the Company’s Board of Directors and is dependent on earnings, operations, capital requirements, general financial condition of the Company, and general business conditions.

Accounting Policies, by Policy

Accounting Policies, by Policy (Policies)	3 Months Ended
	Sep. 30, 2017
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	U.S. Global Investors, Inc. (the “Company” or “U.S. Global”) has prepared the consolidated financial statements pursuant to accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the United States Securities and Exchange Commission (“SEC”) that permit reduced disclosure for interim periods. The financial information included herein reflects all adjustments (consisting solely of normal recurring adjustments), which are, in management’s opinion, necessary for a fair presentation of results for the interim periods presented. The Company has consistently followed the accounting policies set forth in the notes to the consolidated financial statements in the Company’s Form 10-K for the fiscal year ended June 30, 2017, except for the adoption of new accounting pronouncements discussed below. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, U.S. Global Brokerage, Inc., U.S. Global Investors (Bermuda) Limited, U.S. Global Investors (Canada) Limited (“USCAN”), and U.S. Global Indices, LLC, and its 65 percent interest in Galileo Global Equity Advisor Inc. (“Galileo”). U.S. Global Brokerage, Inc. ceased operations in December 2015. Galileo is consolidated with the operations of the Company. The non-controlling interest in this subsidiary is included in “non-controlling interest in subsidiary” in the equity section of the Consolidated Balance Sheets. Frank Holmes, CEO, and Susan McGee, President and General Counsel, serve as directors of Galileo. There are two primary consolidation models in U.S. GAAP, the variable interest entity (“VIE”) and voting interest entity models. The Company’s evaluation for consolidation includes whether entities in which it has an interest or from which it receives fees are VIEs and whether the Company is the primary beneficiary of any VIEs identified in its analysis. A VIE is an entity in which either (a) the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or (b) the group of holders of the equity investment at risk lack certain characteristics of a controlling financial interest. The primary beneficiary is the entity that has the obligation to absorb a majority of the expected losses or the right to receive the majority of the residual returns and consolidates the VIE on the basis of having a controlling financial interest. The Company holds variable interests in, but is not deemed to be the primary beneficiary of, certain funds it advises, specifically, certain funds in U.S. Global Investors Funds (“USGIF” or the “Funds”) and one of the offshore funds. The Company’s interests in these VIEs consist of the Company’s direct ownership therein and any fees earned but uncollected. See further information about these funds in Notes 2 and 3. In the ordinary course of business, the Company may choose to waive certain fees or assume operating expenses of the funds it advises for competitive, regulatory or contractual reasons (see Note 3 for information regarding fee waivers). The Company has not provided financial support to any of these entities outside the ordinary course of business. The Company’s risk of loss with respect to these VIEs is limited to the carrying value of its investments in, and fees receivable from, the entities. The Company does not consolidate these VIEs because it is not the primary beneficiary. The Company’s total exposure to unconsolidated VIEs, consisting of the carrying value of investment securities and receivables for fees, was $9.1 million at September 30, 2017, and $11.3 million at June 30, 2017. The Company holds a variable interest in a fund advised by Galileo, but this fund does not qualify as a VIE. Since the fund is not a VIE, the Company evaluated if it should consolidate the fund under the voting interest entity model. Under the voting interest model, for legal entities other than partnerships, the usual condition for control is ownership, directly or indirectly, of more than 50 percent of the outstanding voting shares over an entity. The Company does not have control of the fund and, therefore, does not consolidate the fund. However, the Company owns approximately 30 percent of the fund, and is considered to have the ability to exercise significant influence. Thus, the investment is accounted for under the equity method of accounting. See further information about this investment in Note 2. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts have been reclassified for comparative purposes. The results of operations for the three months ended September 30, 2017, are not necessarily indicative of the results to be expected for the entire year. The unaudited interim financial information in these condensed financial statements should be read in conjunction with the consolidated financial statements contained in the Company’s annual report.
