From 25 Oct 2026 (London's clocks go back to GMT): London 15:00–00:00 (next day), New York 19:00–04:00 (next day), overlap 19:00–00:00 (next day).
Currency futures and licensing in Thailand
From 2 official sources, checked 8 October 2026.
What the official sources say
On TFEX, the Thailand Futures Exchange, USD/THB futures (1,000 US dollars a contract) trade in three sessions, each after a short pre-open: 09:45–12:30, 13:45–16:55 and 18:50 to 03:00 the next morning, Thai time. The night session spans the whole London–New York overlap on Thai time.
Thailand's SEC keeps an Investor Alert list of businesses that appear to operate without its licence or registration, built from investors' reports; one of its categories is unlicensed securities and derivatives business. Check a firm against it before you deposit.
This is a summary of public sources, not legal or tax advice. Rules and hours change: check with your regulator, and with your broker, before you open an account.

Why London–New York, with the source
London and New York overlap when the two largest trading locations' business days coincide; the UK alone handled 38% of global FX turnover in April 2025 (BIS). That is a fact about volume by location, not a forecast for any pair or hour.
