Is the stock market open today? Memorial Day market and mail guide

On May 25, 2026 — Memorial Day — the major U.S. equity exchanges, the New York Stock Exchange (NYSE) and Nasdaq, are closed for the full trading day; regular stock trading will not occur and activity is expected to resume on Tuesday.

The holiday closure follows the exchanges’ official 2026 holiday calendars and coincides with other federal observances that affect settlement and reporting cycles. Many futures and derivatives venues operate on modified hours for the holiday; CME Group has announced changes to settlement practices and will not derive certain settlement prices on May 25, while other futures exchanges have issued adjusted trading schedules.

Although cash equity markets are closed, futures, energy markets and U.S. Treasury-related instruments may trade with thinner liquidity and wider spreads, increasing short-term volatility risk. Traders should be aware that price discovery can continue offshore or in overnight sessions, but execution cost and slippage typically rise during U.S. market holidays.

The U.S. Postal Service (USPS) has confirmed that retail post office locations will be closed and regular mail delivery suspended on May 25, 2026; customers are directed to online and self-service options for non-urgent needs. This pause can affect e-commerce flows and logistics planning for businesses expecting package pickups or deliveries on the holiday.

Market observers expect a pickup in activity on Tuesday as pent-up orders and scheduled corporate or economic releases are processed. Investors and portfolio managers should monitor the specific holiday schedules published by exchanges and clearinghouses, and treat intraday trades with extra caution due to reduced liquidity and altered settlement timelines.
