Vietnam stock market opening hours
Vietnam trades on Vietnam time (ICT, UTC+7). The practical issue for foreign investors is not only when the market is open, but which session type is active and whether your broker accepts orders during breaks or holidays.
Regular trading day
The core Vietnamese equity trading day runs through a morning session, a lunch break, and an afternoon session. HOSE opens with an order-matching auction from 09:00 to 09:15 ICT, followed by continuous matching until 11:30. The market closes for a lunch break from 11:30 to 13:00. Afternoon continuous matching runs from 13:00 to 14:30, and a closing auction runs from 14:30 to 14:45. HNX follows a similar schedule but with slightly different closing auction timing. UPCOM, the unlisted public company market, trades continuously from 09:00 to 11:30 and 13:00 to 14:45 with no formal auction phases. Aveluro uses 09:00–11:30 and 13:00–14:45 ICT as the regular market-hours window for live updates.
Order phases and matching rules
Opening and closing auctions use periodic call auctions, where orders accumulate and execute at a single clearing price. During continuous matching, orders execute immediately against the order book at the best available price. This distinction matters for foreign investors because limit orders placed during auction phases behave differently than during continuous trading. Market orders are not available on HOSE — only limit orders are accepted. HNX accepts both market and limit orders during continuous sessions. If your broker queues orders placed outside trading hours, confirm whether they enter the book at the next session's opening auction or are held until continuous matching begins.
Price limits and circuit breakers
HOSE enforces a daily price limit of ±7% from the reference price (the previous session's closing price). HNX allows ±10%, and UPCOM allows ±15%. These limits mean a stock can hit its ceiling or floor price and effectively stop trading in one direction for the rest of the day. Foreign investors accustomed to markets without daily price caps should factor this into position sizing and order timing. A stock at its floor price may have no buyers, making it impossible to exit until the next session.
Settlement cycle: T+2
Vietnam equities settle on a T+2 basis. After buying shares, they are available in your account two business days later. You cannot sell shares you purchased today until T+2, which means day trading is not possible on the same stock. Cash settlement also follows T+2, so proceeds from a sale are not available for reinvestment until two days later. This affects portfolio rebalancing speed and means foreign investors need to plan cash positions ahead of intended trades.
Holidays and non-trading days
Vietnamese public holidays follow the lunar calendar for Tet (Vietnamese New Year, typically late January to mid-February) and fixed dates for Reunification Day (April 30), Labour Day (May 1), and National Day (September 2). The exchange publishes its holiday calendar annually. Trading is also closed on weekends. Foreign investors should note that Tet typically results in a full week of market closure, and the days surrounding Tet often see reduced liquidity as local participants wind down positions ahead of the holiday.
Time zone conversion for common markets
Vietnam (ICT, UTC+7) opens before European markets and after East Asian markets. For a trader in New York (EST/EDT), the Vietnamese morning session runs from roughly 22:00 to 00:30 the previous evening. For London (GMT/BST), it runs from 02:00 to 04:30 and 06:00 to 07:45. For Singapore/Hong Kong (SGT/HKT, UTC+8), sessions run from 10:00 to 12:30 and 14:00 to 15:45. Plan your order entry and monitoring windows accordingly, especially if your broker does not queue out-of-hours orders.
