Patriots' Day is not a recognized market holiday. Major U.S. financial exchanges, including the New York Stock Exchange (NYSE) and Nasdaq, remain open for trading and operate on a normal schedule. The day's status as a state-level observance, rather than a federal holiday, is the primary reason it does not affect market operations.
U.S. financial market closures are determined by a schedule of federal holidays, such as New Year's Day, Memorial Day, and Thanksgiving Day, as recommended by regulatory bodies like the Securities Industry and Financial Markets Association (SIFMA). Patriots' Day, celebrated on the third Monday of April, is an official public holiday only in the states of Massachusetts and Maine. While state government offices and many local businesses in those states close in observance, this has no bearing on the operational calendar of the national securities and bond markets.
Consequently, for all investors, traders, and financial institutions, it is a standard business day. All trading, clearing, and settlement activities proceed as usual. While some physical bank branches in the observing states may be closed, national electronic banking and trading systems function without interruption, requiring market participants to treat the day as any other active trading session.
