When do the world's stock markets open? (GMT guide)

A 24-hour GMT timeline with the trading sessions of Asia-Pacific, Europe and the Americas, and the London–New York overlap highlighted from 14:30 to 16:30.

Stocks trade somewhere on Earth almost around the clock on every weekday. Wellington opens the day at 21:00 GMT, and Wall Street closes it at 21:00 GMT the next evening.

Below is every major exchange with its local hours and the same session in GMT, so you can convert once to your own time zone and stop guessing.

One warning before you read: clocks are moving right now. Europe left summer time on 25 October, and the US follows on 1 November. All GMT times below are the winter schedule, valid from 2 November 2026 until March 2027. Summer-time differences are listed at the end.

Americas

The Americas close the global day, and almost all of them sync to New York.

  • USA – NYSE & Nasdaq (New York): 09:30–16:00 ET → 14:30–21:00 GMT. Pre-market 04:00–09:30 ET (09:00–14:30 GMT), after-hours 16:00–20:00 ET (21:00–01:00 GMT).

The trading day in GMT, and the overlaps that matter

The busiest hours of the global day are 14:30–16:30 GMT, when London and New York are open together.

  1. 21:00 – Wellington opens
  2. 23:00 – Sydney opens
  3. 00:00 – Tokyo and Seoul open
  4. 01:30 – Shanghai and Hong Kong open
  5. 03:45 – Mumbai opens
  6. 07:00 – Istanbul, Riyadh and Johannesburg open; Tokyo and Shanghai are closed
  7. 08:00 – London, Frankfurt and Paris open; Hong Kong closes
  8. 10:00 – Mumbai closes
  9. 14:30 – New York and Toronto open: the London–New York overlap begins
  10. 16:30 – London and Europe close
  11. 21:00 – New York closes, and Wellington opens again

Three windows worth knowing:

  • London + New York (14:30–16:30 GMT): the deepest liquidity of the day, and when US data releases hit European prices.
  • Asia → Europe handover (07:00–08:00 GMT): Asia’s closing moves get priced into the European open.
  • The quiet gap (21:00–23:00 GMT): only New Zealand and US after-hours trading are live.

Daylight saving, and what changes on 6 December

Local hours never move; the GMT times do, whenever a country changes its clocks.

  • Between the two clock changes (26–30 October 2026): Europe is already on winter time but the US is not, so New York opens at 13:30 GMT and the London–New York overlap runs three hours instead of two.
  • US summer time (from 14 March 2027): New York, Toronto and Mexico City trade 13:30–20:00 GMT; São Paulo shortens its session again.
  • European summer time (from 28 March 2027): London and the continent shift one hour earlier, to 07:00–15:30 GMT.
  • Southern hemisphere (from 4 April 2027): Sydney moves to 00:00–06:00 GMT and Wellington to 22:00–04:45 GMT.
  • No clock changes: Japan, China, Hong Kong, Korea, Taiwan, Singapore, India, Turkey, Saudi Arabia and South Africa keep the same GMT times all year.

The big one: Wall Street goes (almost) 24 hours. Nasdaq and NYSE Arca are targeting 6 December 2026 for 23-hour trading, five days a week, still subject to SEC approval and data-feed readiness. The new overnight session runs 21:00–04:00 ET, Sunday to Thursday, which is 02:00–09:00 GMT. Once it is live, US stocks will trade during the Asian and European mornings, and the only pause will be one hour each night.

Trading hours can change for holidays and special sessions. Check the exchange’s own calendar before you trade.
