Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a government money market fund and seeks to maintain a stable price of $1.00 per share. The Fund seeks to achieve its investment objective by investing at least 99.5% of its total assets in cash, securities issued or guaranteed by the United States or certain U.S. government agencies or instrumentalities (“U.S. Government Securities”) and/or repurchase agreements that are collateralized fully by these types of obligations. In addition, the Fund must invest, under normal circumstances, at least 80% of its net assets, plus any borrowings for investment purposes, in U.S. Government Securities and repurchase agreements collateralized fully by these types of obligations. The Fund will invest in securities with maturities of (or deemed maturities of) 397 days or less and will maintain a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average portfolio life of 120 days or less.

The Fund invests in issues of the U.S. Treasury, such as bills, notes and bonds, and issues of U.S. government agencies and instrumentalities established under the authority of an Act of Congress. This includes securities of various U.S. government agencies which, while chartered or sponsored by Acts of Congress, are neither issued nor guaranteed by the U.S. Treasury. The Fund may invest in, among other things, obligations that are supported by the “full faith and credit” of the United States (e.g., obligations guaranteed by the Government National Mortgage Association); supported by the right of the issuer to borrow from the U.S. Treasury (e.g., obligations of the Federal National Mortgage Association); or supported only by the credit of the agency or instrumentality (e.g., obligations of the Federal Farm Credit Bank). The Fund may also invest in repurchase agreements that are collateralized by U.S. Government Securities, as well as securities of other money market funds that primarily invest in U.S. Government Securities and repurchase agreements collateralized by U.S. Government Securities.

In purchasing and selling securities for the Fund, portfolio managers consider the credit analysis performed by HSBC Global Asset Management (USA) Inc., the Fund’s investment adviser (the “Adviser”). Portfolio managers select investments from an approved credit list compiled by the Adviser’s global credit analysts, who have conducted an independent qualitative and quantitative review of each issuer on the list. Safety is prioritized, with additional emphasis placed on liquidity and yield.

Risk [Text Block] rr_RiskTextBlock The Fund has the following principal investment risks. The risks are presented in an order intended to facilitate readability, and their order does not imply that the realization of one risk is likely to occur more frequently than another risk, nor does it imply that the realization of one risk is likely to have a greater adverse impact than another risk.
Risk Closing [Text Block] rr_RiskClosingTextBlock

Risk is inherent in all investing. You could lose money by 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. An investment in the Fund is not a bank account or a deposit of HSBC Bank USA, N.A. and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not expect that the sponsor will provide financial support to the Fund at any time, including during periods of market stress.

The 7-day yield information reflects any contractual and voluntary fee waivers/expense reimbursements. Without these fee waivers/expense reimbursements, the yields would have been lower.

HSBC U.S. Government Money Market Fund | Debt Instruments Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Debt Instruments Risk: The risks of investing in debt instruments include:
HSBC U.S. Government Money Market Fund | Credit Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Credit Risk: The Fund could lose money if an issuer or guarantor of a debt instrument is unable or unwilling to make or perceived to be unable or unwilling to make timely payments of interest or principal, defaults on its other obligations or enters bankruptcy. The issuer or guarantor could also suffer a rapid decrease in credit quality rating, which would adversely affect the value and liquidity of the investment.
HSBC U.S. Government Money Market Fund | Interest Rate Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Interest Rate Risk: Fluctuations in interest rates may affect the yield, volatility, liquidity and value of investments in income producing or debt instruments. Generally, if interest rates rise, the value of such investments will fall. A low interest rate environment poses additional risks to the Fund, because low yields on the Fund’s portfolio holdings may have an adverse impact on the Fund’s ability to provide a positive yield to shareholders, pay expenses out of current income, or, at times, maintain a stable $1.00 share price and/or achieve its investment objective. The risks associated with changing interest rates may have unpredictable effects on the markets and the Fund’s investments.
HSBC U.S. Government Money Market Fund | Inventory Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Inventory Risk: The market-making capacity in debt markets has declined as a result of reduced broker-dealer inventories relative to fund assets, reduced broker-dealer proprietary trading activity and increased regulatory capital requirements for financial institutions such as banks. Because market makers provide stability to a market through their intermediary services, a significant reduction in dealer market-making capacity has the potential to decrease liquidity and increase volatility in the debt markets. A decrease in liquidity may affect the ability of the Fund to pay redemption proceeds within the allowable time period.
HSBC U.S. Government Money Market Fund | Market Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Market Risk: The value of the Fund’s investments may decline due to changing economic, political, social, regulatory or market conditions. Market risk may affect a single issuer, industry or section of the economy or it may affect the economy as a whole. Events such as war, acts of terrorism, social unrest, natural disasters, rapid changes in interest rates, the spread of infectious illness or other public health threats could also significantly impact the Fund and its investments.
HSBC U.S. Government Money Market Fund | Repurchase Agreements [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Repurchase Agreements: If the seller in a repurchase agreement defaults on its obligation to repurchase the underlying securities at a time when the value of these securities has declined, the Fund may incur a loss upon disposition of the securities. There is also a risk that the seller of the agreement may become insolvent and subject to liquidation.
HSBC U.S. Government Money Market Fund | Stable NAV Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Stable NAV Risk: The Fund may not be able to maintain an NAV per share of $1.00 (a “Stable NAV”) at all times. The failure of other money market funds to maintain a Stable NAV (or the perceived threat of such a failure) could adversely affect the Fund’s NAV. Shareholders of the Fund should not rely on or expect the Adviser or an affiliate to help the Fund maintain a Stable NAV.
HSBC U.S. Government Money Market Fund | U.S. Government Securities Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock U.S. Government Securities Risk: There are different types of U.S. Government Securities with different levels of credit risk. U.S. Government Securities issued or guaranteed by the U.S. Treasury and/or supported by the full faith and credit of the United States have the lowest credit risk, although they are not risk free. A U.S. government-sponsored entity, although chartered or sponsored by an Act of Congress, may issue securities that are neither insured nor guaranteed by the U.S. Treasury and are riskier than those that are.

Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund is a government money market fund and seeks to maintain a stable price of $1.00 per share. The Fund seeks to achieve its investment objective by investing, under normal market conditions, exclusively in direct obligations of the U.S. Treasury. The Fund will invest in securities with maturities of (or deemed maturities of) 397 days or less and will maintain a dollar-weighted average portfolio maturity of 60 days or less and a dollar-weighted average portfolio life of 120 days or less.

The U.S. Treasury issues various types of marketable securities consisting of bills, notes, bonds and other debt securities. The Fund will not invest in securities issued or guaranteed by agencies or instrumentalities of the U.S. government, will not enter into loans of its portfolio securities and will not, under normal conditions, invest in repurchase agreements.

Under adverse market conditions, the Fund may temporarily invest in repurchase agreements collateralized by U.S. Treasury obligations. These securities may entail more risk than the types of securities in which the Fund typically invests. Additionally, as an alternative to investing in negatively yielding securities, the Fund may also elect to hold uninvested cash with the Fund’s custodian.

Risk is inherent in all investing. You could lose money by 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. An investment in the Fund is not a bank account or a deposit of HSBC Bank USA, N.A. and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund’s sponsor is not required to reimburse the Fund for losses, and you should not expect that the sponsor will provide financial support to the Fund at any time, including during periods of market stress.

Risk [Text Block] rr_RiskTextBlock Debt Instruments Risk: The risks of investing in debt instruments include:
HSBC U.S. Treasury Money Market Fund | Credit Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Credit Risk: The Fund could lose money if an issuer or guarantor of a debt instrument is unable or unwilling to make or perceived to be unable or unwilling to make timely payments of interest or principal, defaults on its other obligations or enters bankruptcy. The issuer or guarantor could also suffer a rapid decrease in credit quality rating, which would adversely affect the value and liquidity of the investment.
HSBC U.S. Treasury Money Market Fund | Interest Rate Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Interest Rate Risk: Fluctuations in interest rates may affect the yield, volatility, liquidity and value of investments in income producing or debt instruments. Generally, if interest rates rise, the value of such investments will fall. A low interest rate environment poses additional risks to the Fund, because low yields on the Fund’s portfolio holdings may have an adverse impact on the Fund’s ability to provide a positive yield to shareholders, pay expenses out of current income, or, at times, maintain a stable $1.00 share price and/or achieve its investment objective. The risks associated with changing interest rates may have unpredictable effects on the markets and the Fund’s investments.
HSBC U.S. Treasury Money Market Fund | Inventory Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Inventory Risk: The market-making capacity in debt markets has declined as a result of reduced broker-dealer inventories relative to fund assets, reduced broker-dealer proprietary trading activity and increased regulatory capital requirements for financial institutions such as banks. Because market makers provide stability to a market through their intermediary services, a significant reduction in dealer market-making capacity has the potential to decrease liquidity and increase volatility in the debt markets. A decrease in liquidity may affect the ability of the Fund to pay redemption proceeds within the allowable time period.
HSBC U.S. Treasury Money Market Fund | Market Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Market Risk: The value of the Fund’s investments may decline due to changing economic, political, social, regulatory or market conditions. Market risk may affect a section of the economy or it may affect the economy as a whole. Events such as war, acts of terrorism, social unrest, natural disasters, rapid changes in interest rates, the spread of infectious illness or other public health threats could also significantly impact the Fund and its investments.
HSBC U.S. Treasury Money Market Fund | Stable NAV Risk [Member]  
Prospectus [Line Items] rr_ProspectusLineItems  
Risk [Text Block] rr_RiskTextBlock Stable NAV Risk: The Fund may not be able to maintain an NAV per share of $1.00 (a “Stable NAV”) at all times. The failure of other money market funds to maintain a Stable NAV (or the perceived threat of such a failure) could adversely affect the Fund’s NAV. Shareholders of the Fund should not rely on or expect the Adviser or an affiliate to help the Fund maintain a Stable NAV.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing all of its assets in the Portfolio, which has the same investment objective as the Fund. For simplicity purposes, this prospectus may use the term “Fund” to include the Portfolio. The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus borrowings for investment purposes, in U.S. equity securities of small- and mid-cap companies that meet the Subadviser’s (as defined below) fundamental and environmental, social, and governance (“ESG”) criteria described below (measured at the time of purchase). Small- and mid-cap companies generally are defined as those companies with market capitalizations within the range represented in the Russell 2500® Growth Index (as of December 31, 2023, between approximately $13 million and $20 billion), the Fund’s broad-based securities market index. The Fund may also invest in equity securities of larger, more established companies.

Radiant Global Investors LLC (formerly, RadiantESG Global Investors LLC), the Portfolio’s subadviser (“Radiant” or the “Subadviser”), uses proprietary models to evaluate companies along key fundamental characteristics as well as ESG criteria. In managing the Portfolio, Radiant seeks to identify and invest in companies with compelling fundamentals and attractive ESG profiles.

The Subadviser’s fundamental view of companies is primarily assessed using two proprietary models: Comprehensive Quality and Stock Sentiment.

•The Comprehensive Quality Model seeks to identify companies with higher profitability, greater earnings stability, and higher perceived sustainability of earnings as indicated by lower levels of asset growth, lower use of accruals, and other measures.
•The Stock Sentiment Model seeks to identify companies with attractive earnings revisions, positive industry momentum, and positive news sentiment.

The Subadviser uses its proprietary Positive Change Model to evaluate companies using ESG criteria. The Positive Change Model seeks to identify companies that are “ESG Leaders” (companies believed to have leading ESG positioning in their relevant industries/sectors), “ESG Evolvers” (companies believed to be improving their ESG positioning in their relevant industries/sectors) and “Impact Leaders” (companies with products and services believed to be aligned to the United Nations Sustainable Development Goals (“UNSDGs”)). The Positive Change Model assigns multiple “scores” to each company in the Portfolio’s investment universe based on these ESG and Impact criteria. Company-level E, S, and G scores and combined ESG scores, along with company-level Impact scores, are the primary criteria in Radiant’s assessment of a company’s ESG profile. The Subadviser believes that these scores convey material information on a company’s operational strengths and weaknesses as well as a company’s positioning with respect to systemic forces (including climate change) that Radiant believes will economically affect all companies. The Subadviser uses proprietary and third-party data to assess ESG and Impact exposure to specific criteria, including, for example, greenhouse gas (“GHG”) emissions, water use, diversity, human rights, corporate ethical behavior and board structure/independence. The importance and weighting of ESG and Impact criteria will vary by industry/sector. Radiant defines “Impact” as the percentage of net revenue aligned to the UNSDGs, a globally accepted standard for evaluating investment impact.

Radiant uses a “bottom-up” investment process in which stocks deemed to exhibit excessive tail risk (e.g., micro-cap companies, companies with excessive valuations or volatility, companies that operate in controversial business lines, and companies facing severe controversies) are first excluded from the Portfolio’s investment universe and not considered for investment. Companies that operate in controversial business lines are generally those that are directly engaged in and/or derive significant revenue from, business lines that are believed to be inconsistent with environmental and socially-aware investing, including:

•Tobacco;
•Coal mining/production; and
•Casinos and gambling.*

* Please see the SAI for complete list of all business-line exclusions.

Companies facing severe controversies are generally those that are believed to be the worst offenders when it comes to unethical behavior, environmental damage, legal liability or violation of human rights and liberties.

After excluding stocks that are deemed to exhibit excessive tail risk, an initial portfolio is constructed from companies scoring highly along both fundamental and ESG criteria, subject to risk management criteria (e.g., industry/sector exposure and position size); then Radiant performs a qualitative review before constructing the final portfolio. After purchase, the Subadviser will sell a stock if the company no longer exhibits both compelling fundamentals and an attractive ESG profile.

The Subadviser believes that incorporating ESG criteria into its investment process is an important complement to its two fundamental models (Comprehensive Quality and Stock Sentiment). The Subadviser’s objective in evaluating ESG considerations is to identify threats faced by companies, including transition and regulatory risk, as well as investment opportunities associated with the more efficient use of natural resources, more effective use of human resources and better governance. The Subadviser also believes that attractive ESG characteristics will economically advantage companies relative to their peers, potentially characterized by superior earnings growth, fewer incidents of legal or regulatory action, greater talent attraction and retention, and fewer incidents of value-destroying ethical or governance malfeasance.

The Fund will invest primarily in U.S. common stocks, but may, to a limited extent, invest in other types of securities, such as non-U.S. securities listed on U.S. securities exchanges.

For example, the Fund generally will not seek to invest in companies that operate in, or derive a specific amount of revenue from, controversial business lines (e.g., tobacco, nuclear armaments and other controversial weapons, and thermal coal extraction), or companies with severe controversies (e.g., severe violators of human rights and liberties). As a result, the Fund could underperform or outperform other mutual funds that do not consider ESG criteria in their investment processes. In evaluating a company, the Subadviser is dependent upon third-party data that it believes to be reliable, but it does not guarantee the accuracy of such third-party data. ESG data from third-party data providers may be incomplete, inaccurate or unavailable and may vary significantly from one third-party data provider to another, which could adversely affect the analysis of ESG criteria relevant to a particular company. Investing on the basis of ESG criteria is qualitative and subjective by nature and there can be no assurance that the process utilized by the Subadviser or any third-party research or data providers or any judgment exercised by the Subadviser will reflect the views of any particular investor or result in effective investment decisions for the Fund.

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Portfolio’s portfolio turnover rate was 103% of the average value of its portfolio.

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

The Fund seeks to achieve its investment objective by investing all of its assets in the Portfolio, which has the same investment objective as the Fund. For simplicity purposes, this prospectus may use the term “Fund” to include the Portfolio. The Fund seeks to achieve its investment objective by investing, under normal circumstances, at least 80% of its net assets, plus borrowings for investment purposes, in U.S. equity securities of small- and mid-cap companies that meet the Subadviser’s (as defined below) fundamental and environmental, social, and governance (“ESG”) criteria described below (measured at the time of purchase). Small- and mid-cap companies generally are defined as those companies with market capitalizations within the range represented in the Russell 2500® Growth Index (as of December 31, 2023, between approximately $13 million and $20 billion), the Fund’s broad-based securities market index. The Fund may also invest in equity securities of larger, more established companies.

Radiant Global Investors LLC (formerly, RadiantESG Global Investors LLC), the Portfolio’s subadviser (“Radiant” or the “Subadviser”), uses proprietary models to evaluate companies along key fundamental characteristics as well as ESG criteria. In managing the Portfolio, Radiant seeks to identify and invest in companies with compelling fundamentals and attractive ESG profiles.

The Subadviser’s fundamental view of companies is primarily assessed using two proprietary models: Comprehensive Quality and Stock Sentiment.

•The Comprehensive Quality Model seeks to identify companies with higher profitability, greater earnings stability, and higher perceived sustainability of earnings as indicated by lower levels of asset growth, lower use of accruals and other measures.
•The Stock Sentiment Model seeks to identify companies with attractive earnings revisions, positive industry momentum and positive news sentiment.

The Subadviser uses its proprietary Positive Change Model to evaluate companies using ESG criteria. The Positive Change Model seeks to identify companies that are “ESG Leaders” (companies believed to have leading ESG positioning in their relevant industries/sectors), “ESG Evolvers” (companies believed to be improving their ESG positioning in their relevant industries/sectors) and “Impact Leaders” (companies with products and services believed to be aligned to the United Nations Sustainable Development Goals (“UNSDGs”)). The Positive Change Model assigns multiple “scores” to each company in the Portfolio’s investment universe based on these ESG and Impact criteria. Company-level E, S and G scores and combined ESG scores, along with company-level Impact scores, are the primary criteria in Radiant’s assessment of a company’s ESG profile. The Subadviser believes that these scores convey material information on a company’s operational strengths and weaknesses as well as a company’s positioning with

respect to systemic forces (including climate change) that Radiant believes will economically affect all companies. The Subadviser uses proprietary and third-party data to assess ESG and Impact exposure to specific criteria, including, for example, greenhouse gas (“GHG”) emissions, water use, diversity, human rights, corporate ethical behavior and board structure/independence. The importance and weighting of ESG and Impact criteria will vary by industry/sector. Radiant defines “Impact” as the percentage of net revenue aligned to the UNSDGs, a globally accepted standard for evaluating investment impact.

Radiant uses a “bottom-up” investment process in which stocks deemed to exhibit excessive tail risk (e.g., micro-cap companies, companies with excessive valuations or volatility, companies that operate in controversial business lines and companies facing severe controversies) are first excluded from the Portfolio’s investment universe and not considered for investment. Companies that operate in controversial business lines are generally those that are directly engaged in, and/or derive significant revenue from, business lines that are believed to be inconsistent with environmental and socially-aware investing, including:

•Tobacco;
•Coal mining/production; and
•Casinos and gambling.*

*   Please see the SAI for complete list of all business-line exclusions.

Companies facing severe controversies are generally those that are believed to be the worst offenders when it comes to unethical behavior, environmental damage, legal liability or violation of human rights and liberties.

After excluding stocks that are deemed to exhibit excessive tail risk, an initial portfolio is constructed from companies scoring highly along both fundamental and ESG criteria, subject to risk management criteria (e.g., industry/sector exposure and position size); then Radiant performs a qualitative review before constructing the final portfolio. After purchase, the Subadviser will sell a stock if the company no longer exhibits both compelling fundamentals and an attractive ESG profile.

The Subadviser believes that incorporating ESG criteria into its investment process is an important complement to its two fundamental models (Comprehensive Quality and Stock Sentiment). The Subadviser’s objective in evaluating ESG considerations is to identify threats faced by companies, including transition and regulatory risk, as well as investment opportunities associated with the more efficient use of natural resources, more effective use of human resources and better governance. The Subadviser also believes that attractive ESG characteristics will economically advantage companies relative to their peers, potentially characterized by superior earnings growth, fewer incidents of legal or regulatory action, greater talent attraction and retention, and fewer incidents of value-destroying ethical or governance malfeasance.

The Fund will invest primarily in U.S. common stocks, but may, to a limited extent, invest in other types of securities, such as non-U.S. securities listed on U.S. securities exchanges.

[2] The Total Annual Fund Operating Expenses may not equal the expense ratio stated in the Fund’s most recent annual report and financial highlights. The expense ratio in the financial highlights reflects the operating expenses of the Fund and does not include indirect expenses associated with the Fund’s investments in other money market funds (acquired fund fees and expenses). Without acquired fund fees and expenses, Total Annual Fund Operating Expenses After Fee Waiver and/or Expense Reimbursement would have been 0.48%, 0.23%, 0.13%, 0.18%, 0.20%, 0.18% and 0.23% for Class A Shares, Class E Shares, Class I Shares, Intermediary Shares, Intermediary Service Shares, Class P Shares and Class Y Shares, respectively.

Any amounts contractually waived or reimbursed by the Adviser will be subject to repayment by the Fund to the Adviser within three years, calculated monthly from when the waiver or reimbursement was recorded, to the extent that the repayment will not cause the Fund’s operating expenses to exceed the contractual expense limit that was in effect at the time of such waiver or reimbursement. The expense limitation shall be in effect until February 28, 2025. The Expense Limitation Agreement shall terminate upon the termination of the Investment Advisory Contract between the Fund and the Adviser, or it may be terminated upon written notice to the Adviser by the Trust’s Board of Trustees.

The 1 year, 5 years and 10 years average annual return is not provided for Class E Shares because there were no Class E shareholders as of December 31, 2023.
