Strategy [Heading] oef_StrategyHeading Principal Investment Strategies of the Fund
Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock
The Fund is a money market fund that intends to qualify as a “government money market fund,” in accordance with Rule 2a-7 under the Investment Company Act of 1940, as amended (Rule 2a-7). As a government money market fund, the Fund must invest at least 99.5% of its total assets in cash, government securities and/or repurchase agreements that are “collateralized fully” (i.e., backed by cash or government securities). The securities in which the Fund invests may have fixed, floating or variable interest rates. The Fund may also invest in affiliated and unaffiliated government money market funds.
Under normal market conditions, the Fund invests at least 80% of its net assets (plus borrowings, if any, for investment purposes) in government securities and repurchase agreements that are collateralized by government securities. In contrast to the Fund’s 99.5% policy, the Fund’s 80% policy
does not include cash or repurchase agreements collateralized by cash. The 80% investment policy is a non-fundamental investment policy and will not be changed without 60 days’ advance notice to shareholders. Government security generally means any security issued or guaranteed as to principal or interest by the United States or by a person controlled or supervised by and acting as an instrumentality of the government of the United States.
The Fund invests in conformity with SEC rules and regulation requirements for money market funds for the quality, maturity, diversification and liquidity of investments. The Fund invests only in U.S. dollar-denominated securities maturing within 397 calendar days of the date of purchase, with certain exceptions permitted by applicable regulations. The Fund maintains a dollar-weighted average portfolio maturity of no more than 60 calendar days, and a dollar-weighted average life to maturity of portfolio securities of not more than 120 calendar days (determined without reference to exceptions regarding interest rate adjustments). The Fund will limit investments to those securities that are Eligible Securities as defined by applicable regulations at the time of purchase. Eligible Securities are (i) government securities, (ii) shares of other money market funds and (iii) securities determined to present minimal credit risks by Invesco Advisers, Inc. (Invesco or the Adviser) pursuant to guidelines approved by the Fund's Board of Trustees (the Board). In selecting securities for the Fund’s portfolio, the portfolio managers focus on securities that offer safety, liquidity, and a competitive yield. The portfolio managers normally hold portfolio securities to maturity, but may sell a particular security when they deem it advisable, such as when market or credit factors materially change.
Bar Chart and Performance Table [Heading] oef_BarChartAndPerformanceTableHeading Performance Information
Performance Narrative [Text Block] oef_PerformanceNarrativeTextBlock
The bar chart and performance table provide an indication of the risks of investing in the Fund. The Fund has adopted the performance of the Oppenheimer Government Money Fund/VA (the predecessor fund) as the result of a reorganization of the predecessor fund into the Fund, which was consummated after the close of business on May 24, 2019 (the “Reorganization”). Prior to the Reorganization, the Fund had not yet commenced operations. The bar chart shows changes in the performance of the Series I shares of the Fund and the Non-Service Shares of the predecessor fund from year to year as of December 31. The bar chart and performance table below do not reflect charges assessed in connection with your variable product; if they did, the performance shown would be lower. The Fund’s (and the predecessor fund’s) past performance is not necessarily an indication of how the Fund will perform in the future.
The returns shown for periods ending on or prior to May 24, 2019 are those of the Non-Service Shares of the predecessor fund, which are not offered by the Fund. The Non-Service Shares of the predecessor fund were reorganized into Series I shares of the Fund after the close of business on May 24, 2019. Series I shares’ and Series II shares’ returns of the Fund will be different from the Non-Service Shares’ returns of the predecessor fund as they have different expenses.
Fund performance reflects any applicable fee waivers and expense reimbursements. Performance returns would be lower without applicable fee waivers and expense reimbursements.
All Fund performance shown assumes the reinvestment of dividends and capital gains and the effect of the Fund’s expenses.
Effective April 29, 2016, the predecessor fund changed its investment strategy from a prime money market strategy to a strategy that classified the predecessor fund as a “government money market fund,” as defined by Rule 2a-7. Performance shown prior to that date reflects the predecessor fund’s former prime money market strategy, which permitted investments in certain types of securities that as a government money market fund, the predecessor fund (and therefore the Fund) is no longer permitted to hold. Consequently, the performance information below would have been different if the current investment limitations had been in effect during the period prior to the predecessor fund’s conversion to a government money market fund.
The Series I shares and Series II shares invest in the same portfolio of securities and will have substantially similar performance, except to the extent that the expenses borne by each share class differ. Series II shares have higher expenses (and therefore lower performance) resulting from its Rule 12b-1 plan, which provides for a maximum fee equal to an annual rate of 0.25% (expressed as a percentage of average daily net assets of the Fund).
Updated performance information is available on the Fund’s website at www.invesco.com/us.

Money Market Fund Risk. You could lose money investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. The share price of money market funds can fall below the $1.00 share price. The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not rely on or expect that the sponsor will enter into support agreements or take other actions to provide financial support to the Fund or maintain the Fund’s $1.00 share price at any time, including during periods of market stress. The credit quality of the Fund’s holdings can change rapidly in certain markets, and the default of a single holding could have an adverse impact on the Fund’s share price. The Fund’s share price can also be negatively affected during periods of high redemption pressures, illiquid markets, and/or significant market volatility.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Debt Securities Risk. The prices of debt securities held by the Fund will be affected by changes in interest rates, the creditworthiness of the issuer and other factors. An increase in prevailing interest rates typically causes the value of existing debt securities to fall and often has a greater
impact on longer-duration debt securities and higher quality debt securities. Falling interest rates will cause the Fund to reinvest the proceeds of debt securities that have been repaid by the issuer at lower interest rates. Falling interest rates may also reduce the Fund’s distributable income because interest payments on floating rate debt instruments held by the Fund will decline. The Fund could lose money on investments in debt securities if the issuer or borrower fails to meet its obligations to make interest payments and/or to repay principal in a timely manner. Changes in an issuer’s financial strength, the market’s perception of such strength or in the credit rating of the issuer or the security may affect the value of debt securities. The credit analysis applied to the Fund’s debt securities may fail to anticipate such changes, which could result in buying a debt security at an inopportune time or failing to sell a debt security in advance of a price decline or other credit event.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock
Changing Fixed Income Market Conditions Risk. Increases in the federal funds and equivalent foreign rates or other changes to monetary policy or regulatory actions may expose fixed income markets to heightened volatility, perhaps suddenly and to a significant degree, and to reduced liquidity for certain fixed income investments, particularly those with longer maturities. Such changes and resulting increased volatility may adversely impact the Fund, including its operations, universe of potential investment options, and return potential. It is difficult to predict the impact of interest rate changes on various markets. In addition, decreases in fixed income dealer market-making capacity may also potentially lead to heightened volatility and reduced liquidity in the fixed income markets. As a result, the value of the Fund’s investments may decline. Changes in central bank policies and other governmental actions and political events within the U.S. and abroad may also, among other things, affect investor and consumer expectations and confidence in the financial markets, which could result in higher than normal redemptions by shareholders, which could potentially increase the Fund’s transaction costs.

U.S. Government Obligations Risk. Obligations of U.S. government agencies and authorities receive varying levels of support and may not be backed by the full faith and credit of the U.S. government, which could affect the Fund’s ability to recover should they default. No assurance can be given that the U.S. government will provide financial support to its agencies and authorities if it is not obligated by law to do so.

Risk [Text Block] oef_RiskTextBlock
Market Risk. The market values of the Fund’s investments, and therefore the value of the Fund’s shares, will go up and down, sometimes rapidly or unpredictably. Market risk may affect a single issuer, industry or section of the economy, or it may affect the market as a whole. The value of the Fund’s investments may go up or down due to general market conditions that are not specifically related to the particular issuer. These market conditions may include real or perceived adverse economic conditions, changes in trade regulation or economic sanctions, changes in the general outlook for revenues or corporate earnings, changes in interest or currency rates, regional or global instability and uncertainty, natural or environmental disasters, widespread disease or other public health issues, war, military conflict, acts of terrorism, economic crisis or adverse investor sentiment generally, among others. Certain changes in the U.S. economy in particular, such as when the U.S. economy weakens or when its financial markets decline, may have a material adverse effect on global financial markets as a whole, and on the securities to which the Fund has exposure. Increasingly strained relations between the U.S. and foreign countries, including as a result of economic sanctions and tariffs, may also adversely affect U.S. issuers, as well as non-U.S. issuers.
During a general downturn in the financial markets, multiple asset classes may decline in value. When markets perform well, there can be no assurance that specific investments held by the Fund will rise in value.

Repurchase Agreement Risk. If the seller of a repurchase agreement defaults or otherwise does not fulfill its obligations, the Fund may incur delays and losses arising from selling the underlying securities, enforcing its rights, or declining collateral value.

Risk [Text Block] oef_RiskTextBlock
Yield Risk. The Fund’s yield will vary as the short-term securities in its portfolio mature or are sold and the proceeds are reinvested in other securities. When interest rates are very low or negative, the Fund may not be able to maintain a positive yield or pay Fund expenses out of current income without impairing the Fund’s ability to maintain a stable net asset value. Additionally, inflation may outpace and diminish investment returns over time. Recent and potential future changes in monetary policy made by central banks and/or their governments may affect interest rates.

Risk [Text Block] oef_RiskTextBlock
Floating and Variable Rate Obligations Risk. Some fixed-income securities have variable or floating interest rates that provide for a periodic adjustment in the interest rate paid on the securities. The rate adjustment intervals may be regular and range from daily up to annually, or may be based on an event, such as a change in the stated prevailing market rate. Floating and variable rate securities may be subject to greater liquidity risk than other debt securities, meaning that there may be limitations on the Fund’s ability to sell the securities at any given time. Such securities also may lose value.

Management Risk. The Fund is actively managed and depends heavily on the Adviser’s judgment about markets, interest rates or the attractiveness, relative values, liquidity, or potential appreciation of particular investments made for the Fund’s portfolio. The Fund could experience losses if these judgments prove to be incorrect. There can be no guarantee that the Adviser’s investment techniques or investment decisions will produce the desired results. Additionally, legislative, regulatory, or tax developments may adversely affect management of the Fund and, therefore, the ability of the Fund to achieve its investment objective.
