What Time Does the Asian Stock Market Open EST?
Unlock the exact Eastern Standard Time opening hours for key Asian stock markets, simplifying global trading schedules.
Global financial markets operate around the clock, with different regions beginning their trading days at various times. Understanding these market hours is valuable for investors and those monitoring economic news, especially since Asian markets are among the first to open each global business day.

Calculating Eastern Standard Time Openings
To determine when Asian markets open in Eastern Standard Time (EST, UTC-5), calculate the time difference from their respective UTC offsets. Most openings occur on the preceding calendar day relative to EST.
Tokyo Stock Exchange (TSE): Opens at 9:00 AM JST (UTC+9), which is 7:00 PM EST (14-hour difference).
Shanghai Stock Exchange (SSE): Opens at 9:30 AM CST (UTC+8), which is 8:30 PM EST (13-hour difference).
Hong Kong Stock Exchange (HKEX): Opens at 9:30 AM HKT (UTC+8), which is 8:30 PM EST (13-hour difference).
Singapore Exchange (SGX): Opens at 9:00 AM SGT (UTC+8), which is 8:00 PM EST (13-hour difference).
Australian Securities Exchange (ASX): Opens at 10:00 AM AEST (UTC+10), which is 8:00 PM EST (15-hour difference).
Korea Exchange (KRX): Opens at 9:00 AM KST (UTC+9), which is 7:00 PM EST (14-hour difference).
Indian Exchanges (BSE & NSE): Open at 9:15 AM IST (UTC+5:30), which is 10:45 PM EST (10.5-hour difference).
Daylight Saving Time Considerations
Daylight Saving Time (DST) introduces a shift in the time difference between Eastern Standard Time and Asian market hours. When the United States observes DST, Eastern Standard Time (EST, UTC-5) transitions to Eastern Daylight Time (EDT, UTC-4). This means the time difference between the US East Coast and Asian markets shrinks by one hour. For instance, a market that typically opens at 7:00 PM EST during standard time would open at 8:00 PM EDT when the US is on daylight saving time.
Asian countries generally do not observe daylight saving time, maintaining a consistent local time offset from Coordinated Universal Time (UTC) throughout the year. Any alteration in the Eastern Time opening hour is solely due to the US time zone adjustment. Investors tracking these markets should account for this one-hour shift during the periods when the US transitions between EST and EDT.
