Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	NOTE 2. SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation. The Company, through USCAN, owns 65 percent of the issued and outstanding shares of Galileo, which represents controlling interest of Galileo. Galileo is consolidated with USCAN and the non-controlling interest in this subsidiary is included in “non-controlling interest in subsidiary” in the equity section of the Consolidated Balance Sheets. 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 lacks 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 USGIF and, until November 2017, 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. 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 4 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 $9.6 million at June 30, 2018, and $11.3 million at June 30, 2017. Since the Company is not the primary beneficiary of the above funds it advises, the Company evaluated if it should consolidate 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 any of the above funds it advises; therefore, the Company does not consolidate any of these funds. The Company holds a variable interest in a fund advised by Galileo, and during fiscal 2018 held a variable interest in another fund advised by Galileo, but these funds do not qualify as VIEs. Since the funds are not VIEs, the Company evaluated if it should consolidate the funds 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 funds and, therefore, does not consolidate the funds. However, during fiscal 2018, the Company’s ownership ranged between approximately 23 and 30 percent of one fund until the investment was redeemed in full and between 20 and 25 percent of the other fund, and is considered to have the ability to exercise significant influence. Thus, the investments are accounted for under the equity method of accounting. See further information about these investments in Note 3. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts have been reclassified for comparative purposes. Business Combinations. Cash and Cash Equivalents. Restricted Cash. A reconciliation of cash, cash equivalents, and restricted cash reported from the consolidated balance sheets to the statements of cash flows is shown below: June 30, (dollars in thousands) 2018 2017 Cash and cash equivalents $ 6,364 $ 3,958 Restricted cash 1,000 1,000 Total cash, cash equivalents, and restricted cash $ 7,364 $ 4,958 Investments. Trading Securities. Held-to-Maturity Securities. Available-for-sale Securities. The Company evaluates its available-for-sale investments for other-than-temporary decline in value on a periodic basis. This may exist when the fair value of an investment security has been below the current value for an extended period of time. When a security in the Company’s investment portfolio has an unrealized loss in fair value that is deemed to be other than temporary, the Company reduces the book value of such security to its current fair value, recognizing the credit related decline as a realized loss in the Consolidated Statements of Operations and a revised GAAP cost basis for the security is established. For available-for-sale securities with declines in value deemed other than temporary, the unrealized loss recorded net of tax in accumulated other comprehensive income (loss) is realized as a charge to net income. As discussed further in the Recent Accounting Pronouncements and Developments of this note, the Company will adopt ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities Other Investments.

The Commission indicated that The Tax Cuts and Jobs Act, which was enacted on December 22, 2017, affects companies’ reporting because of the Act’s changes that impact U.S. corporate tax rates, business-related exclusions, and deductions and credits. ASC Topic 740 provides accounting and disclosure guidance on accounting for income taxes under U.S. GAAP. This guidance addresses the recognition of taxes payable or refundable for the current year and the recognition of deferred tax liabilities and deferred tax assets for the future tax consequences of events that have been recognized in an entity’s financial statements or tax returns. ASC Topic 740 also addresses the accounting for income taxes upon a change in tax laws or tax rates. The income tax accounting effect of a change in tax laws or tax rates includes, for example, adjusting (or re-measuring) deferred tax liabilities and deferred tax assets, as well as evaluating whether a valuation allowance is needed for deferred tax assets. The Commission issued SAB 118 to address situations where the accounting under ASC Topic 740 is incomplete for certain income tax effects of the Act upon issuance of an entity’s financial statements for the reporting period in which the Act was enacted. A company’s financial statements that include the reporting period in which the Act was enacted must first reflect the income tax effects of the Act in which the accounting under ASC Topic 740 is complete. These completed amounts would not be provisional amounts. The company would then also report provisional amounts for those specific income tax effects of the Act for which the accounting under ASC Topic 740 will be incomplete but a reasonable estimate can be determined. For any specific income tax effects of the Act for which a reasonable estimate cannot be determined, the company would not report provisional amounts and would continue to apply ASC Topic 740 based on the provisions of the tax laws that were in effect immediately prior to the Act being enacted. For those income tax effects for which the company was not able to determine a reasonable estimate (such that no related provisional amount was reported for the reporting period in which the Act was enacted), the company would report provisional amounts in the first reporting period in which a reasonable estimate can be determined. U.S. Global has revalued its deferred tax assets and liabilities as of the date of enactment and has considered the provisions of SAB 118 related to provisional amounts. See further discussion in Note 12.

Disclosure Text Block Supplement [Abstract]
Investments and Other Noncurrent Assets [Text Block]	NOTE 3 . INVESTMENTS As of June 30, 2018, the Company held investments with a fair value of $15.3 million and a cost basis of $12.3 million. The market value of these investments is approximately 52.8 percent of the Company’s total assets. In addition, the Company held other investments of $2.2 million accounted for under the cost method of accounting and investments of approximately $283,000 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 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 but have readily determinable fair values, are reflected as non-current assets on the Consolidated Balance Sheets at their fair value. Unrealized gains and losses on available-for-sale securities are excluded from earnings and reported in other comprehensive income (loss) 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 equity investments are accounted for under the cost method of accounting and evaluated 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 earnings. Cost basis may also be adjusted for amortization of premium or accretion of discount on debt securities held or to recharacterize distributions from investments in partnerships. The following details the components of the Company’s investments recorded at fair value as of June 30, 2018, and 2017: June 30, 2018 (dollars in thousands) Cost Unrealized Gains Unrealized (Losses) Fair Value Trading securities 1 Mutual funds - Fixed income $ 7,785 $ 22 $ - $ 7,807 Mutual funds - Domestic equity 535 - (163 ) 372 Other 45 - (45 ) - Offshore fund - - - - Total trading securities 8,365 22 (208 ) 8,179 Available-for-sale securities 2 Common stock - Domestic - - - - Common stock - International 2,554 3,213 (94 ) 5,673 Corporate debt - - - - Mutual funds - Fixed income 1,000 - (9 ) 991 Mutual funds - Domestic equity 394 28 - 422 Other - - - - Total available-for-sale securities 3 3,948 3,241 (103 ) 7,086 Total securities at fair value $ 12,313 $ 3,263 $ (311 ) $ 15,265 June 30, 2017 (dollars in thousands) Cost Unrealized Gains Unrealized (Losses) Fair Value Trading securities 1 Mutual funds - Fixed income $ 8,884 $ 50 $ (7 ) $ 8,927 Mutual funds - Domestic equity 535 - (157 ) 378 Other 45 - (45 ) - Offshore fund 1,184 - (769 ) 415 Total trading securities 10,648 50 (978 ) 9,720 Available-for-sale securities 2 Common stock - Domestic 109 4 - 113 Common stock - International 191 12 - 203 Corporate debt 1,042 427 - 1,469 Mutual funds - Fixed income 1,148 1 (5 ) 1,144 Mutual funds - Domestic equity 394 12 - 406 Other 56 10 - 66 Total available-for-sale securities 3 2,940 466 (5 ) 3,401 Total securities at fair value $ 13,588 $ 516 $ (983 ) $ 13,121 1 Unrealized and realized gains and losses on trading securities are included in earnings in the statement of operations. 2 Unrealized gains and losses on available-for-sale securities are excluded from earnings and recorded in other comprehensive income (loss) as a separate component of shareholders’ equity until realized. 3 Net unrealized gains (losses) on available-for-sale securities gross and net of tax as of June 30, 201 8 , are $ 3,138 and $ 2, 089 , respectively, and as of June 30, 201 7 , are $ 461 and $ 461 , respectively. At June 30, 2017, the Company had an available-for-sale investment in corporate debt securities with a par value of approximately $1.7 million which was valued at approximately $1.5 million. The securities were scheduled to mature in 2024. The issuer of the corporate debt redeemed these debt securities early at par value in May 2018. The Company recorded a realized gain in fiscal 2018 related to the early redemption of approximately $638,000. The following summarizes investment income (loss) reflected in earnings for the periods presented. (dollars in thousands) Year Ended June 30, Investment Income 2018 2017 Realized gains on sales of available-for-sale securities $ 669 $ 31 Realized losses on sales of trading securities (736 ) - Unrealized gains on trading securities 742 15 Realized foreign currency losses (59 ) (37 ) Other-than-temporary declines in available-for-sale securities - (411 ) Other-than-temporary declines in securities held at cost - (72 ) Dividend and interest income 888 820 Total Investment Income $ 1,504 $ 346 Proceeds from the sales of available-for-sale investments were approximately $2.1 million and $649,000, for the fiscal years ended June 30, 2018, and June 30, 2017, respectively. Gross gains on sales of available-for-sale investments were $675,000 and $34,000 for fiscal years 2018 and 2017, respectively. Gross losses on sales of available-for-sale investments were $6,000 and $3,000 for fiscal years 2018 and 2017, respectively. The amounts for fiscal 2018 include the proceeds and realized gain from the early redemption of debt securities discussed above. Realized gains and losses on the sale of available-for-sale investments are reclassified from other comprehensive income into investment income. There were no impairment losses during fiscal year 2018. In fiscal year 2017, other-than temporary declines in value on available-for-sale securities of approximately $411,000 were included in investment income. The impairment losses resulted from fair values of certain equity securities being lower than book value. For the year ending June 30, 2017, there were four securities with a combined cost basis of $627,000 that were written down to a combined fair value of $216,000. Also included in investment income for fiscal 2017 was approximately $72,000 in other-than-temporary declines in value on securities held at cost. The impairment loss resulted from the estimated values of certain securities being lower than cost. In fiscal 2017, one security held at cost with a cost basis of $72,000 was written down to zero. In making these determinations, the Company considered the length of time and extent to which the fair value has been less than the 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. The Company reviewed the gross unrealized losses shown as of June 30, 2018, and determined that the losses were not other-than-temporary based on consideration of the nature of the investment and the cause, severity and duration of the loss.

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 included 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 are 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 and accounting 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 each balance sheet date, for the major categories of U.S. Global’s investments measured at fair value on a recurring basis: June 30, 2018 Quoted Prices Significant Other Inputs Significant Unobservable Inputs (dollars in thousands) (Level 1) (Level 2) (Level 3) Total Trading securities Mutual funds - Fixed income $ 7,807 $ - $ - $ 7,807 Mutual funds - Domestic equity 372 - - 372 Other - - - - Offshore fund investment measured at net asset value 1 - Total trading securities 8,179 - - 8,179 Available-for-sale securities Common stock - Domestic - - - - Common stock - International 5,673 - - 5,673 Corporate debt - - - - Mutual funds - Fixed income 991 - - 991 Mutual funds - Domestic equity 422 - - 422 Other - - - - Total available-for-sale securities 7,086 - - 7,086 Total securities at fair value $ 15,265 $ - $ - $ 15,265 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 ex p edient 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 June 30, 2018, and June 30, 2017, 100 percent of the Company’s financial assets measured at fair value are derived from Level 1 inputs. The Company recognizes transfers between levels at the end of each quarter. During the quarter ended September 30, 2017, the Company invested in 10 million common shares of HIVE Blockchain Technologies Ltd. (“HIVE”), a company that is headquartered and traded in Canada with cryptocurrency mining facilities in Iceland and Sweden, at a cost of $2.4 million. The shares are subject to Canadian securities regulations. The investment, classified as available-for-sale, was valued at approximately $5.6 million at June 30, 2018, based on the quoted market price and is classified as Level 1 in the fair value hierarchy. Cryptocurrency markets and related stocks have been, and are expected to continue to be, volatile. Cryptocurrency mining is considered an early stage high-risk industry, and the nature of mining is expected to evolve. There is potential for significant volatility in the market price of HIVE, which could materially impact the investment’s value included on the balance sheet and unrealized gain (loss) recognized in investment income. Two unit trust investment funds managed by Galileo, described below under Investments Classified as Equity Method, also hold common shares of HIVE. The Company had both a direct ownership of HIVE and a combined direct and indirect ownership of HIVE of approximately 3.2 percent as of June 30, 2018. Frank Holmes is the non-executive chairman of HIVE and held shares and options at June 30, 2018. Effective August 31, 2018, upon the retirement of HIVE’s CEO and until a new CEO is hired, Mr. Holmes became Interim Executive Chairman of HIVE. The Company had an investment in an affiliated offshore fund, classified as trading, which invested in companies in the energy and natural resources sectors. The fair value of this investment was estimated based on the net asset value per share at $415,000 as of June 30, 2017. This offshore fund liquidated during the fiscal year ended June 30, 2018. Investments Classified as Equity Method During the quarter ended September 30, 2017, the Company, through USCAN, invested approximately $500,000 in the Galileo Partners Fund, a Canadian unit trust investment fund managed by Galileo. The investment was subsequently redeemed in full during fiscal 2018, and the Company no longer has an investment in the Galileo Partners Fund as of June 30, 2018. During the period of ownership, the Company’s ownership ranged between 23 and 30 percent, and the Company was considered to have the ability to exercise significant influence. Thus, the investment was 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 year ended June 30, 2018, is $1.7 million of equity method income of Galileo Partners Fund. Frank Holmes also directly held an investment in the fund as of June 30, 2018. Summarized income statement information on the Galileo Partners Fund for the period of the Company’s investment is as follows: Galileo Partners Fund Summary Financial Information For the Period from August 31, 2017 (investment) to June 30, 2018 (dollars in thousands) Realized gains on sales of investments $ 6,254 Decrease in unrealized gains on investments (28 ) Fund fees and expenses, including performance fees (1,677 ) Net income of fund $ 4,549 During the year ended June 30, 2018, the Company, through USCAN, invested approximately $401,000 in the Galileo Technology and Blockchain Fund, a Canadian unit trust investment fund managed by Galileo. This fund has a concentration in technology and blockchain companies, which may result in volatility in the fund’s valuation. The Company owns approximately 25 percent of Galileo Technology and Blockchain Fund as of June 30, 2018, and the company is considered to have the ability to exercise significant influence. Thus, the investment is accounted for under the equity method of accounting. Included in other income for the year ended June 30, 2018, is $99,000 of equity method loss for Galileo Technology and Blockchain Fund. The Company’s investment in the fund was valued at approximately $283,000 at June 30, 2018. Frank Holmes also directly held an investment in the fund as of June 30, 2018.

Disclosure Text Block Supplement [Abstract]
Shareholders' Equity and Share-based Payments [Text Block]	NOTE 1 1 . SHAREHOLDERS’ EQUITY The Company has three classes of common equity: class A, class B, and class C common stock. The Company’s class A common stock is traded over-the-counter and is quoted daily under NASDAQ’s Capital Markets under the symbol “GROW.” There is no established public trading market for the Company’s class B and class C common stock. There are no shares of class B stock issued as of June 30, 2018, or 2017. The Company’s class A and class B common stock have no voting privileges. Dividends Dividends of $0.0025 per share per month totaling $393,000 and $394,000 were paid to holders of class A common stock in fiscal years 2018 and 2017, respectively. Dividends of $62,000 and $62,000 were paid to holders of class C common stock in fiscal years 2018 and 2017, respectively. The monthly dividend of $0.0025 is authorized through September 2018 and will be considered for continuation at that time 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. On a per share basis, the holders of the class C common stock and the nonvoting class A common stock participate equally in dividends as declared by the Company’s Board of Directors. Share Repurchase Plan The Company has a share repurchase program, approved by the Board of Directors, authorizing the Company to annually purchase up to $2.75 million of its outstanding common shares, as market and business conditions warrant, on the open market in compliance with Rule 10b-18 of the Securities Exchange Act of 1934 through December 31, 2018. The repurchase program has been in place since December 2012, and the Board of Directors has annually renewed the repurchase program each calendar year. The acquired shares may be used for corporate purposes, including shares issued to employees in the Company’s stock-based compensation programs. As of June 30, 2018, approximately $2.74 million remains available for repurchase under this authorization. During fiscal years 2018 and 2017, the Company repurchased 48,947 and 69,636, respectively, of its class A shares on the open market using cash of $141,000 and $114,000, respectively. To date, the Company has repurchased a total of 540,235 class A shares under the repurchase program using cash of $1.3 million. Other Activity The Company did not grant any shares of class A common stock to employees during fiscal year 2018 or 2017. Grants vest immediately after issuance. The Company granted 7,200 and 3,600 shares of class A common stock at a weighted average fair value of $2.62 and $1.66 to its non-employee directors in fiscal years 2018 and 2017, respectively. Grants vest immediately after issuance. Issuances of treasury stock for grants or bonuses are accounted for using the weighted-average cost basis of the shares issued. During fiscal year 2018, shares were issued, as described above, with a weighted-average cost basis less than current fair value, which resulted in a combined increase to additional paid-in capital of approximately $2,000 for fiscal year 2018. During fiscal year 2017, shares were issued with a weighted-average cost basis greater than current fair value, which resulted in a combined negative adjustment to additional paid-in capital of approximately $5,000 for fiscal year 2017. Shareholders of class C shares are allowed to convert to class A. During fiscal years 2018 and 2017, 90 and 180 shares, respectively, were converted from class C to class A. Conversions are one class A share for one class C share and are recorded at par value. There are no restrictions or requirements to convert. Stock-based compensation In November 1989, the Board of Directors adopted the 1989 Non-Qualified Stock Option Plan (“1989 Plan”), amended in December 1991, which provides for the granting of options to purchase 1,600,000 shares of the Company’s class A common stock to directors, officers and employees of the Company and its subsidiaries. Options issued under the 1989 Plan vest six months from the grant date or 20 percent on the first, second, third, fourth, and fifth anniversaries of the grant date. Options issued under the 1989 Plan expire ten years after issuance. No options were granted in fiscal years 2018 or 2017. As of June 30, 2018, there were no options outstanding under the 1989 Plan. In April 1997, the Board of Directors adopted the 1997 Non-Qualified Stock Option Plan (“1997 Plan”), which provides for the granting of stock appreciation rights (SARs) and/or options to purchase 400,000 shares of the Company’s class A common stock to directors, officers, and employees of the Company and its subsidiaries. Options issued under the 1997 Plan expire ten years after issuance. In fiscal year 2018, 2,000 options were granted with a fair value, net of tax, of approximately $4,000. The options granted in fiscal year 2018 will vest over six months through September 2018. No options were granted in fiscal year 2017.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	NOTE 1 2 . 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 U.S. statutory rate for the consolidated U.S. federal income tax return was approximately 34 percent for the fiscal year ended June 30, 2017. The current applicable Canadian statutory rate for the Canadian subsidiaries is approximately 26.5 percent. The Tax Cuts and Jobs Act (“the Act”) was enacted on December 22, 2017. The Act reduces the U.S. federal corporate tax rate from 35 percent to 21 percent, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. In the second quarter, the Company revised its estimated annual effective rate to reflect a change in its U.S. federal statutory rate from 34 percent to 21 percent. See further discussion in the Provisional amounts At June 30, 2018, the Company has not completed its accounting for the tax effects of enactment of the Act; however, in certain cases, as described below, the Company has made a reasonable estimate of the effects on existing deferred tax balances and the one-time transition tax. The Securities and Exchange Commission has issued guidance that allows for a measurement period of up to one year after the enactment date of the Act to finalize the recording of the related tax impacts. The final transitional impacts of the Act may differ from the initial estimates. Prior to the enactment of Act, the Company had not recorded U.S. income taxes on the undistributed earnings of the Company’s foreign subsidiaries. The earnings of the foreign subsidiaries were considered to be indefinitely reinvested, and as a result, no deferred tax liability was previously recorded. The Company has reevaluated its historic indefinite reinvestment assertion as a result of the enactment of the Act and determined that historical or future undistributed earnings of foreign subsidiaries are no longer considered to be indefinitely reinvested. As a result, for the period ended June 30, 2018, the Company recorded a deferred tax expense and liability related to foreign withholding taxes in the amount of approximately $57,000 for those undistributed earnings which are no longer considered indefinitely invested. The Act also established new tax provisions that become effective in future periods, including but not limited to eliminating the corporate alternative minimum tax, creating the base erosion anti-abuse tax (“BEAT”), establishing new limitations on deductible interest expense and certain executive compensation, creating a new provision designed to tax global intangible low-tax income (“GILTI”) and generally eliminating U.S. Federal income taxes on dividends from foreign subsidiaries. Under the new GILTI tax rules, an accounting policy election must be made to either treat taxes due on future GILTI inclusions in U.S. taxable income as a current period expense when incurred or reflect as a component of deferred taxes. This provision is effective for tax years beginning on or after January 1, 2018, which for the Company would be the fiscal year beginning on July 1, 2018 (fiscal 2019). The Company’s analysis of the new GILTI rules and its impacts is currently incomplete. Accordingly, the Company has not yet made a policy election regarding the treatment of the GILTI tax. Provisional amounts Deferred tax assets and liabilities: Certain domestic-related deferred tax assets and liabilities were remeasured in the second quarter of fiscal 2018 based on the rates at which they are expected to reverse in the future, which is generally 21 percent. The remeasurement at the lower tax rate on domestic-related deferred tax assets and liabilities resulted in a deferred tax benefit of approximately $1.4 million. However, the Company is still analyzing certain aspects of the Act and refining the calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. As a valuation allowance is recorded for the full amount of these net deferred tax assets, the remeasurement of the net deferred tax assets was offset by a corresponding remeasurement of the valuation allowance. Foreign tax effects: The one-time transition tax is based on total post-1986 earnings and profits (“E&P”) that were previously deferred from U.S. income taxes. The Company recorded a provisional amount for the one-time transition tax for foreign subsidiaries of $17,000. The Company has not yet completed its calculation of the total post-1986 E&P for these foreign subsidiaries. Further, the transition tax is based in part on the amount of those earnings held in cash and other specified assets. This amount may change when the calculations are finalized. Carryovers For U.S. federal income tax purposes at June 30, 2018, the Company has U.S. federal net operating loss carryovers of $4.7 million with $2.0 million and $2.7 million expiring in fiscal years 2035 and 2036, respectively. The Company has capital loss carryovers of $1.1 million with $750,000 and $348,000 expiring in fiscal years 2022 and 2023, respectively. The Company has charitable contribution carryovers totaling approximately $69,000 with $34,000; $19,000; $5,000; and $11,000 expiring in fiscal years 2019, 2020, 2021, and 2023, respectively. For Canadian income tax purposes, Galileo has net operating loss carryovers of $338,000 with $102,000; $44,000; $121,000; and $71,000 expiring in fiscal years 2027, 2030, 2036 and 2037, respectively. 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. Additional Disclosures 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 June 30, 2018, and 2017, a valuation allowance of $1.7 million and $3.3 million, respectively, was included to fully reserve for net operating loss carryovers, other carryovers and certain book/tax differences in the balance sheet.

RELATED PARTY TRANSACTIONS On June 30, 2018, and 2017, the Company had $9.6 million and $11.1 million, respectively, at fair value invested in USGIF and offshore funds the Company advised. These amounts were included in the Consolidated Balance Sheet as “trading securities” and “available-for-sale securities” in fiscal years 2018 and 2017. The Company recorded $131,000 and $110,000 in income from dividends and capital gain distributions and $10,000 and $15,000 in net recognized gains (losses) on its investments in the Funds and offshore clients for fiscal years 2018 and 2017, respectively. The offshore clients liquidated during fiscal 2018. In addition, the Company had $283,000 at June 30, 2018, invested in a fund advised by Galileo accounted for under the equity method of accounting. During fiscal 2018, the Company was also invested in another fund advised by Galileo accounted for under the equity method of accounting. This investment was no longer held at June 30, 2018. The Company recorded income from equity method investments of $1.6 million in fiscal 2018. See further discussion of these investments in Note 3. The Company earned advisory and administrative services fees, as applicable, from the various funds for which it and its subsidiaries act as investment adviser, as disclosed in Note 4. Receivables include amounts due from the funds for those fees and out-of-pocket expenses, net of amounts payable to the funds for expense reimbursements. As of June 30, 2018, and 2017, the Company had $419,000 and $396,000, respectively, of receivables from mutual funds included in the Consolidated Balance Sheets within “receivables.” As discussed in Note 3, the Company holds an investment in HIVE valued at $5.6 million as of June 30, 2018. Frank Holmes, a director and Chief Executive Officer of the Company, is the non-executive chairman of HIVE, for which he received director fees from HIVE during fiscal 2018. Mr. Holmes held shares and options of HIVE at June 30, 2018. Effective August 31, 2018, upon the retirement of HIVE’s CEO and until a new CEO is hired, Mr. Holmes became Interim Executive Chairman of HIVE.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	NOTE 1 7 . 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 of Directors has authorized a monthly dividend of $0.0025 per share from July 2018 through September 2018, at which time it will be considered for continuation by the Board of Directors. 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. The total amount of cash dividends to be paid to class A and class C shareholders from July 2018 to September 2018 will be approximately $113,000.

Accounting Policies, by Policy

Accounting Policies, by Policy (Policies)	12 Months Ended

Accounting Policies [Abstract]
Consolidation, Policy [Policy Text Block]	Principles of Consolidation. The Company, through USCAN, owns 65 percent of the issued and outstanding shares of Galileo, which represents controlling interest of Galileo. Galileo is consolidated with USCAN and the non-controlling interest in this subsidiary is included in “non-controlling interest in subsidiary” in the equity section of the Consolidated Balance Sheets. 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 lacks 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 USGIF and, until November 2017, 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. 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 4 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 $9.6 million at June 30, 2018, and $11.3 million at June 30, 2017. Since the Company is not the primary beneficiary of the above funds it advises, the Company evaluated if it should consolidate 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 any of the above funds it advises; therefore, the Company does not consolidate any of these funds. The Company holds a variable interest in a fund advised by Galileo, and during fiscal 2018 held a variable interest in another fund advised by Galileo, but these funds do not qualify as VIEs. Since the funds are not VIEs, the Company evaluated if it should consolidate the funds 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 funds and, therefore, does not consolidate the funds. However, during fiscal 2018, the Company’s ownership ranged between approximately 23 and 30 percent of one fund until the investment was redeemed in full and between 20 and 25 percent of the other fund, and is considered to have the ability to exercise significant influence. Thus, the investments are accounted for under the equity method of accounting. See further information about these investments in Note 3. All significant intercompany balances and transactions have been eliminated in consolidation. Certain amounts have been reclassified for comparative purposes.

Investment, Policy [Policy Text Block]	Investments. Trading Securities. Held-to-Maturity Securities. Available-for-sale Securities. The Company evaluates its available-for-sale investments for other-than-temporary decline in value on a periodic basis. This may exist when the fair value of an investment security has been below the current value for an extended period of time. When a security in the Company’s investment portfolio has an unrealized loss in fair value that is deemed to be other than temporary, the Company reduces the book value of such security to its current fair value, recognizing the credit related decline as a realized loss in the Consolidated Statements of Operations and a revised GAAP cost basis for the security is established. For available-for-sale securities with declines in value deemed other than temporary, the unrealized loss recorded net of tax in accumulated other comprehensive income (loss) is realized as a charge to net income. As discussed further in the Recent Accounting Pronouncements and Developments of this note, the Company will adopt ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities Other Investments.

The Commission indicated that The Tax Cuts and Jobs Act, which was enacted on December 22, 2017, affects companies’ reporting because of the Act’s changes that impact U.S. corporate tax rates, business-related exclusions, and deductions and credits. ASC Topic 740 provides accounting and disclosure guidance on accounting for income taxes under U.S. GAAP. This guidance addresses the recognition of taxes payable or refundable for the current year and the recognition of deferred tax liabilities and deferred tax assets for the future tax consequences of events that have been recognized in an entity’s financial statements or tax returns. ASC Topic 740 also addresses the accounting for income taxes upon a change in tax laws or tax rates. The income tax accounting effect of a change in tax laws or tax rates includes, for example, adjusting (or re-measuring) deferred tax liabilities and deferred tax assets, as well as evaluating whether a valuation allowance is needed for deferred tax assets. The Commission issued SAB 118 to address situations where the accounting under ASC Topic 740 is incomplete for certain income tax effects of the Act upon issuance of an entity’s financial statements for the reporting period in which the Act was enacted. A company’s financial statements that include the reporting period in which the Act was enacted must first reflect the income tax effects of the Act in which the accounting under ASC Topic 740 is complete. These completed amounts would not be provisional amounts. The company would then also report provisional amounts for those specific income tax effects of the Act for which the accounting under ASC Topic 740 will be incomplete but a reasonable estimate can be determined. For any specific income tax effects of the Act for which a reasonable estimate cannot be determined, the company would not report provisional amounts and would continue to apply ASC Topic 740 based on the provisions of the tax laws that were in effect immediately prior to the Act being enacted. For those income tax effects for which the company was not able to determine a reasonable estimate (such that no related provisional amount was reported for the reporting period in which the Act was enacted), the company would report provisional amounts in the first reporting period in which a reasonable estimate can be determined. U.S. Global has revalued its deferred tax assets and liabilities as of the date of enactment and has considered the provisions of SAB 118 related to provisional amounts. See further discussion in Note 12.
