When does the Indonesian market open? When does it pause during the day, and when does trading stop entirely? These are practical questions faced daily by traders, investors, and institutions active in Indonesia’s financial markets.
As participation in Indonesian equities, bonds, and derivatives continues to grow, knowing the market schedule has become essential. Indonesian trading hours determine when prices can move and trades can be executed, while national holidays define periods when markets are fully closed. Both directly influence volatility, spreads, and strategic positioning across asset classes.
Quick Summary
Indonesia’s financial markets operate on a centralised schedule based on Jakarta time (WIB, UTC+7), ensuring consistency for local and international participants.
The Indonesian Stock Exchange uses a two-session trading structure with a mandatory midday break, which plays a key role in shaping intraday liquidity and execution timing.
Price discovery occurs at both the open and the close, via auction mechanisms that are particularly important for institutional order flow.
Liquidity is most concentrated during the morning session, especially between 09:00 and 10:30, when market participation is at its highest.
Indonesia’s extensive holiday calendar, driven by national and religious observances, regularly affects trading continuity and liquidity conditions.
Eid al-Fitr closures represent the most significant annual market interruption, often leading to thinner volumes ahead of the holiday and price adjustments on reopening.
Trading hours overlap with major Asian markets but not with Europe or the US, making overnight risk management essential for global investors.

Quick Market Notes
Price discovery occurs twice daily, at the open and at the close, both via auction mechanisms.
The highest liquidity is typically observed during Session I, particularly between 09:00 and 10:30
No new trades are executed during post-trading
The midday break is a hard halt and materially impacts intraday execution strategies.
During Ramadan, IDX generally applies the Friday trading schedule to all weekdays, mainly by extending the midday break.
| Session | Trading Hours (WIB) | Notes |
|---|---|---|
| Pre-Opening | 08:45 – 08:59 | Order input and opening auction preparation |
| Session I | 09:00 – 11:30 | Continuous trading (morning session) |
| Break | 11:30 – 14:00 | Extended midday break during Ramadan |
| Session II | 14:00 – 15:49 | Continuous trading (afternoon session) |
| Pre-Closing | 15:50 – 16:00 | Order input for closing auction |
| Post-Closing | 16:01 – 16:15 | Reporting and administrative processing only |
Continuous trading hours remain unchanged, but are split by a longer pause.
Exact implementation is formally announced by the exchange each year, and traders should always confirm the official circular.
Indonesia’s market closes well before Europe and North America open, meaning global macro developments released during Western hours are reflected in Indonesian prices on the following trading day.
| Market | Time Zone | Overlap With IDX |
|---|---|---|
| Tokyo | UTC+9 | Partial (Morning) |
| Hong Kong | UTC+8 | Strong |
| Singapore | UTC+8 | Strong |
| London | UTC+0 | None |
| New York | UTC−5 | None |
Indonesia maintains one of the most extensive holiday calendars among major emerging markets. Holidays are defined through a combination of fixed national events and movable religious observances.
Categories of Market Holidays
National Holidays
Commemorate political and historical milestones such as Independence Day and Pancasila Day.
Religious Holidays
Indonesia officially recognises multiple religions, resulting in public holidays for Islamic, Christian, Hindu, and Buddhist observances. Islamic holidays account for the largest share and shift annually.
Joint Leave Days
Additional collective leave days may surround the major holidays. While not always official market closures, trading activity often declines sharply.
| Holiday | Date (2026) | Day | IDX Market Status |
|---|---|---|---|
| New Year’s Day | 1 January 2026 | Thursday | Closed |
| Isra Mi’raj | 16 January 2026 | Friday | Closed |
| Chinese New Year (Imlek) | 17 February 2026 | Tuesday | Closed |
| Nyepi (Balinese Day of Silence) | 19 March 2026 | Thursday | Closed |
| Eid al-Fitr (Idul Fitri) | 21–22 March 2026 | Saturday–Sunday | Closed (Weekend)* |
| Good Friday | 3 April 2026 | Friday | Closed |
| International Labour Day | 1 May 2026 | Friday | Closed |
| Ascension of Jesus Christ | 14 May 2026 | Thursday | Closed |
| Eid al-Adha | 27 May 2026 | Wednesday | Closed |
| Vesak Day | 31 May 2026 | Sunday | Closed (Weekend) |
| Pancasila Day | 1 June 2026 | Monday | Closed |
| Independence Day | 17 August 2026 | Monday | Closed |
| Prophet Muhammad’s Birthday (Maulid Nabi) | 25 August 2026 | Tuesday | Closed |
| Christmas Day | 25 December 2026 | Friday | Closed |
* Eid al-Fitr is typically accompanied by government-designated collective leave (cuti bersama), which often results in several consecutive non-trading days.
Additional notes:
Eid al-Fitr represents the most significant annual market disruption, with the longest continuous closure and the sharpest liquidity decline ahead of the holiday.
Holidays falling on Fridays or Mondays frequently create long weekends, reducing participation and execution quality.
Official holiday dates for Islamic observances may be confirmed closer to the event, based on lunar sightings.
Indonesia’s capital markets are centralised in Jakarta and operate through a single national exchange. As a result, Indonesia's trading hours and national holidays apply uniformly across the market and directly determine when onshore trading and settlement can take place.
The Indonesia Stock Exchange is the country’s sole stock exchange, providing a centralised venue for trading equities, exchange-traded funds, bonds, sukuk, and structured products for domestic and international investors.
Trading activity is concentrated in major banking, commodity-linked, consumer, and infrastructure sectors, with all transactions governed by standardised rules that make Indonesia's trading hours and national holidays a critical reference point for market participation.
Indonesia spans multiple time zones, but all IDX trading activity is conducted using Western Indonesia Time (WIB), which corresponds to Jakarta local time. This uniform time standard ensures operational consistency across the market and provides clarity for international participants tracking Indonesia's trading hours and national holidays.
Liquidity often contracts meaningfully ahead of long holiday periods as domestic institutions reduce exposure and foreign investors limit gap risk.
While pre-holiday volatility may compress, price gaps can emerge when markets reopen, especially if global markets moved materially during the closure.
Although equity trading halts, offshore pricing of Indonesian currency-linked instruments may continue, leading to adjustment pressure once onshore markets resume.
Intraday momentum is typically strongest in the morning session, while closing auctions often attract position-adjustment flows.
Portfolio rebalancing should be completed well-ahead of extended closures to avoid forced execution in thin conditions.
Hedging, index tracking, and ETF exposure must account for Indonesia’s non-synchronous trading hours relative to Western markets.
The Indonesian Stock Exchange opens in the morning based on Jakarta time, starting with a pre-opening session where orders are entered and adjusted. Continuous trading begins shortly after, once the opening auction establishes initial market prices.
No. The Indonesian Stock Exchange operates only from Monday to Friday. It remains fully closed on Saturdays and Sundays, with no trading, auctions, or post-trading activities conducted during weekends.
Indonesian market holidays can lead to full trading suspensions or extended closures, particularly around major religious observances. These holidays often reduce liquidity ahead of closures and may result in price adjustments when markets reopen, making advance planning essential for traders and investors.
Eid al-Fitr leads to the longest scheduled trading interruption in Indonesia, with markets closed for multiple consecutive days. Liquidity typically declines ahead of the holiday, and price adjustments may occur when trading resumes, making timing and exposure management especially important.
Yes. While most equity products follow the standard IDX trading schedule, other instruments such as bonds, sukuk, and derivatives may operate under different trading windows or reporting frameworks, depending on the market segment and execution mechanism involved.
Traders often reduce position sizes and avoid aggressive execution ahead of extended Indonesian market holidays. Lower liquidity and thinner order books can increase slippage and gap risk, making conservative positioning and advance trade planning more effective during pre-holiday periods.
Indonesia’s trading hours and national holidays define a market rhythm shaped by regional integration and deeply rooted cultural traditions. The structured daily sessions of the Indonesia Stock Exchange provide operational clarity, while the extensive holiday calendar introduces distinctive liquidity and timing considerations.
Success in Indonesian markets depends not only on economic analysis and valuation discipline, but also on precise operational awareness. Understanding when the market trades, when it pauses, and how participants behave around those pauses is essential for managing risk and capturing opportunity in one of Asia’s most dynamic emerging economies.
