Risk [Text Block] |
| Principal Risks |
An investment in the fund is not a bank account
or a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC)
or any other government agency. 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. The
fund may impose a fee upon the sale of your shares. The fund's yield will fluctuate as the short-term
securities in its portfolio mature or are sold and the proceeds are reinvested in securities with different
interest rates. BNY Mellon Investment Adviser, Inc. and its affiliates are not required to reimburse
the fund for losses, and you should not expect that BNY Mellon Investment Adviser, Inc. or its affiliates
will provide financial support to the fund at any time, including during periods of market stress. The
following are the principal risks that could reduce the fund's income level and/or share price:
|
| Risk Lose Money [Member] |
You could lose money by investing in the fund.
|
| Risk Money Market Fund Price Fluctuates [Member] |
The fund's yield will fluctuate as the short-term
securities in its portfolio mature or are sold and the proceeds are reinvested in securities with different
interest rates.
|
| Risk Money Market Fund May Not Preserve Dollar [Member] |
Although the fund seeks
to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so.
|
| Risk Not Insured [Member] |
An investment in the fund is not a bank account
or a bank deposit. It is not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC)
or any other government agency.
|
| · Interest rate risk |
· Interest
rate risk: This risk refers to the decline in the prices of fixed-income
securities that may accompany a rise in the overall level of interest rates. A sharp and unexpected
rise in interest rates could impair the fund's ability to maintain a stable net asset
value. A wide variety of market factors can cause interest rates to rise, including central bank monetary
policy, rising inflation and changes in general economic conditions. It is difficult to predict the
pace at which central banks or monetary authorities may increase (or decrease) interest rates or the
timing, frequency, or magnitude of such changes. Changing interest rates may have unpredictable effects
on markets, may result in heightened market volatility and may detract
from fund performance. For floating and variable rate obligations, there may be a lag between an actual
change in the underlying interest rate benchmark and the reset time for an interest payment of such an
obligation, which could harm or benefit the fund, depending on the interest rate environment or other
circumstances.
|
| · Liquidity risk |
· Liquidity risk: When
there is little or no active trading market for specific types of securities, it can become more difficult
to sell the securities in a timely manner at or near their perceived value. In such a market, the value
of such securities may fall dramatically, potentially impairing the fund's ability to maintain a stable
net asset value.
|
| · Credit risk |
· Credit risk: Failure
of an issuer of a security to make timely interest or principal payments when due, or a decline or perception
of a decline in the credit quality of the security, can cause the security's price to fall. Although
the fund invests only in high quality debt securities, the credit quality of the securities held by the
fund can change rapidly in certain market environments, and the default or a significant price decline
of a single holding could impair the fund's ability to maintain a stable net asset value.
|
| · Liquidity fee risk |
· Liquidity
fee risk: The fund may impose a discretionary liquidity fee upon the redemption of fund
shares if such a fee is determined to be in the best interests of the fund. The fund's board has delegated
to Dreyfus the responsibility to make liquidity fee determinations pursuant to board-approved written
guidelines. If a discretionary liquidity fee is imposed by the fund, it would reduce the amount a redeeming
shareholder would receive upon the sale of fund shares during the period the fee is in effect. If the
fund imposes a discretionary liquidity fee, it is possible that it may return the fee to shareholders
in the form of a distribution at a later time.
|
| · Banking industry risk |
· Banking industry risk: The risks
generally associated with concentrating investments (i.e., hold 25% or more of its total assets) in the
banking industry include interest rate risk, credit risk, and regulatory developments relating to the
banking industry. Banks may be particularly susceptible to certain economic factors such as interest
rate changes, adverse developments in the real estate market, fiscal and monetary policy and general
economic cycles. An adverse development in the banking industry (domestic or foreign) may affect the
value of the fund's investments more than if such investments were not concentrated in the banking industry.
|
| · Foreign investment risk |
· Foreign
investment risk: The risks generally associated with dollar-denominated foreign
investments include economic and political developments, seizure or nationalization of deposits, imposition
of taxes or other restrictions on payment of principal and interest. The imposition of sanctions, confiscations,
trade restrictions (including tariffs) and other government restrictions by the United States and other
governments, or from problems in share registration, settlement or custody, may also result in losses.
In addition, the fund will be subject to the risk that an issuer of foreign sovereign debt or the government
authorities that control the repayment of the debt may be unable or unwilling to repay the principal
or interest when due.
|
| · U.S. Treasury securities risk |
· U.S. Treasury securities risk:
A security backed by the U.S. Treasury or the full faith and credit of the United States is guaranteed
only as to the timely payment of interest and principal when held to maturity, but the market prices
for such securities are not guaranteed and will fluctuate.
|
| · Government securities risk |
· Government securities risk: Not
all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith
and credit of the U.S. Treasury. Some obligations are backed only by the credit of the issuing agency
or instrumentality, and in some cases there may be some risk of default by the issuer. Any guarantee
by the U.S. government or its agencies or instrumentalities of a security held by the fund does not apply
to the market value of such security or to shares of the fund itself.
|
| · Repurchase agreement counterparty risk |
· Repurchase
agreement counterparty risk: The fund is subject to the risk that a counterparty
in a repurchase agreement and/or, for a tri-party repurchase agreement, the third party bank providing
payment administration, collateral custody and management services for the transaction, could fail to
honor the terms of the agreement. If this occurs, the fund may suffer a loss if the proceeds from the
sale of the underlying securities are less than the repurchase price.
|
| · Asset-backed securities risk |
· Asset-backed
securities risk: Asset-backed securities are subject to credit, prepayment
and extension risk, and may be more volatile, less liquid and more difficult to price accurately than
more traditional debt securities. General downturns in the economy could cause the value of asset-backed
securities to fall. Asset-backed securities are often subject to more rapid repayment than their stated
maturity date would indicate as a result of the pass-through of prepayments of principal on the underlying
loans.
|
| · Market risk |
· Market risk: The
value of the securities in which the fund invests may be affected by political, regulatory, economic
and social developments. In addition, turbulence in financial markets and reduced liquidity in fixed-income
markets may negatively affect many issuers, which could adversely affect the fund. Global economies
and financial markets are becoming increasingly interconnected, and conditions and events in one country,
region or financial market may adversely impact issuers in a different country, region or financial market.
These risks may be magnified if certain events or developments adversely interrupt the global supply
chain; in these and other circumstances, such risks might affect companies world-wide. Local, regional
or global events such as war, acts of terrorism, natural disasters, the spread of infectious illness
or other public health issues, recessions, elevated levels of government debt, changes in trade regulation
or economic sanctions, internal unrest and discord, or other events could have a significant impact on
the fund and its investments.
