The forex market is a 24-hour relay race. Sydney passes the baton to Tokyo. Tokyo hands off to London. London passes to New York. New York closes for the day, and Sydney opens the next round.
For South African traders, this matters more than it does for traders sitting in any one financial centre. Our country sits in a time zone (SAST, UTC+2) that does not observe daylight saving, while three of the four global sessions do. The result: the forex day on a South African clock shifts on its own four times a year.
This guide is the master reference for when the forex market opens in South Africa, how each session lines up in SAST, where the overlaps are, and when daylight saving shifts the day on your screen.
Forex Market Opening and Closing Times in South Africa
The forex market opens at 23:00 SAST on Sunday night and closes at 23:00 SAST on Friday night. It runs continuously, 24 hours a day, five days a week.
The exact open and close times shift by an hour depending on whether the major financial centres are observing daylight saving. Most of the year, in South African winter, the market opens at 23:00 SAST Sunday and closes at 23:00 SAST Friday. In South African summer, when Australia is on AEDT but the UK and US are not, the cycle compresses slightly and the close can fall as late as 00:00 Saturday SAST.
Between Friday close and Sunday open, the market is effectively dark. Your broker may show price quotes but liquidity is virtually nil. Most retail brokers do not allow new positions between Friday 23:00 SAST and Sunday 23:00 SAST.
The Four Global Sessions in SAST
The 24-hour forex day is broken into four sessions, each anchored to a financial centre. They overlap at the edges, which is where the deepest liquidity sits.
Sydney (the opener)
The first session of the week. Opens Sunday 23:00 SAST in summer (Australia on AEDT, October to April) or 00:00 SAST in winter (Australia on AEST, April to October). Thin liquidity. Home market for AUD and NZD. The Sunday-evening open is the only weekly reset window in forex. See our full guide on the Sydney session in South Africa.
Tokyo (the JPY engine)
Opens at 02:00 SAST year-round (Japan does not observe DST). The most active part of the wider Asian session. Drives JPY pair movement, with the Tokyo Fix at 02:55 SAST a daily volatility moment. See our full guide on the Tokyo session in South Africa.
London (the volume centre)
Opens at 09:00 SAST in summer (UK on BST) or 10:00 SAST in winter (UK on GMT). The single most liquid forex session globally. EUR/USD, GBP/USD, USD/CHF all see their busiest moves here. See our full guide on the London session in South Africa.
New York (the close)
Opens at 14:00 SAST in summer (US on EDT) or 15:00 SAST in winter (US on EST). News-driven; most major US economic releases (NFP, CPI, Fed decisions) hit during this session. Closes at 23:00 or 00:00 SAST, depending on DST. See our full guide on the New York session in South Africa.
For the umbrella view that combines Sydney and Tokyo, see our Asian session guide.
When Each Session Opens and Closes in SAST
The exact SAST hours depend on which regions are currently on DST. Here are the two main scenarios:
SA winter (June to August, the most common scenario)
Australia on AEST (no DST). UK on BST (DST active). US on EDT (DST active).
| Session | Open (SAST) | Close (SAST) | Hours |
|---|---|---|---|
| Sydney | 00:00 | 09:00 | 9 |
| Tokyo | 02:00 | 11:00 | 9 |
| London | 09:00 | 17:00 | 8 |
| New York | 14:00 | 23:00 | 9 |
SA summer (December to February)
Australia on AEDT (DST active). UK on GMT (no DST). US on EST (no DST).
| Session | Open (SAST) | Close (SAST) | Hours |
|---|---|---|---|
| Sydney | 23:00 | 08:00 | 9 |
| Tokyo | 02:00 | 11:00 | 9 |
| London | 10:00 | 18:00 | 8 |
| New York | 15:00 | 00:00 (next day) | 9 |
The transition months (March, April, October, November) carry mixed regimes. Always check the calendar for the current state of each region’s DST status.
Daylight Saving Time and Forex Market Hours
South Africa stays on SAST (UTC+2) year-round. It does not observe daylight saving. But three of the four major forex centres do, on different schedules:
- Australia (Sydney): AEDT (UTC+11) from October to April. AEST (UTC+10) the rest of the year. Southern hemisphere, so DST aligns with SA summer.
- Japan (Tokyo): No DST. JST is UTC+9 year-round. The stable anchor of the forex day.
- United Kingdom (London): BST (UTC+1) from late March to late October. GMT (UTC+0) the rest of the year.
- United States (New York): EDT (UTC−4) from second Sunday in March to first Sunday in November. EST (UTC−5) the rest of the year.
Because SA does not shift, all DST changes happen on your local clock. When Australia springs forward in October, Sydney opens at 23:00 SAST instead of 00:00. When the UK and US spring forward in March, London opens at 09:00 SAST and New York at 14:00 SAST, both one hour earlier than during their winter.
Mark the four transition dates on your calendar:
- Second Sunday in March: UK and US spring forward. London and New York shift one hour earlier on SAST.
- First Sunday in April: Australia falls back. Sydney shifts one hour later on SAST.
- First Sunday in October: Australia springs forward. Sydney shifts one hour earlier on SAST.
- Last Sunday in October (UK) / first Sunday in November (US): UK and US fall back. London and New York shift one hour later on SAST.
Session Overlaps That Matter for SA Traders
Overlaps are where liquidity peaks. Two are worth knowing in detail:
Sydney–Tokyo overlap (02:00 to 08:00 / 09:00 SAST)
The deepest liquidity window of the Asian trading day. Both Sydney and Tokyo banks are active. JPY pairs (USD/JPY, AUD/JPY) and AUD/NZD see their cleanest moves. The Tokyo Fix at 02:55 SAST sits inside this window.
London–New York overlap (14:00 to 17:00 / 18:00 SAST)
The most active window of the entire global forex day. Two of the three largest financial centres open at once. US economic data (NFP, CPI, Fed) lands in this window. The London close at 17:00 SAST often produces a final volatility burst as European traders square positions before going home.
Most South African traders structure their day around the London–New York overlap. It falls inside the local working day, the spreads are tightest, and the cleanest setups of the global day appear here. For the deeper play, see our best time to trade forex in South Africa guide.
When Is the Forex Market Closed?
The forex market is closed in three scenarios:
- Weekends. From Friday 23:00 SAST to Sunday 23:00 SAST (winter SA) or 22:00 SAST (summer SA). Brokers freeze positions. Weekend news (geopolitical, central-bank weekend statements) builds up unpriced until the Sunday open.
- Major global holidays. The two reliable closures are Christmas Day (25 December) and New Year’s Day (1 January). Many brokers also close on Good Friday and Easter Monday. Some regional holidays (US Thanksgiving, UK bank holidays) thin liquidity dramatically without fully closing the market.
- Daily rollover. Not a closure, but a brief pause around 23:00 SAST when brokers credit or debit swap fees on overnight positions. Spreads can widen 5 to 10 pips for 30 seconds. Most platforms display a notification.
The weekend gap is the biggest of these for South African traders. Positions held over the weekend are exposed to whatever happens in Asia between Friday close and Sunday open without any way to react. Some traders close all positions ahead of the close on Friday; others use stop-losses set far enough to absorb a gap. Both are valid; trading into the weekend without a plan is not.
Why Forex Hours Matter for South African Traders
Four reasons the forex clock matters more than the average trader thinks:
- Liquidity defines spread. A pair traded at the London-NY overlap has tighter spreads than the same pair traded at 03:00 SAST during quiet Asian hours. Cost of the trade follows liquidity.
- Volatility defines opportunity. The clean trends and breakouts South African traders want sit inside specific 2 to 4 hour windows. Outside those windows, the market drifts and chops.
- News timing is fixed. NFP at 14:30 SAST on the first Friday of every month. RBA at 05:30 SAST on the first Tuesday. Fed rate decisions at 20:00 SAST on Wednesdays. If you do not know when news lands in SAST, you are trading blind.
- DST shifts move your edge. Setups that work at 15:00 SAST in winter (mid-overlap, US session just opened) do not work at 15:00 SAST in summer (no US session yet). Many traders miss this and lose a quarter twice a year.
The South African time-zone advantage is real: the most liquid window of the global forex day, the London-NY overlap, sits squarely inside your normal working day. Most American traders are too early. Most Asian traders are too late. SA hits the sweet spot.
Practical Trading Examples by Session
Five practical reads of the clock from a South African desk:
- 09:00 SAST (BST summer) or 10:00 SAST (GMT winter): London opens. Mark the Asian range. Watch EUR/USD and GBP/USD for the opening breakout.
- 14:00 SAST (EDT summer) or 15:00 SAST (EST winter): New York opens. London-NY overlap begins. Tightest spreads of the day. Best three hours for scalping the majors.
- 14:30 SAST (first Friday of the month): Non-Farm Payrolls. Step back or scale down. EUR/USD can move 50 to 100 pips in minutes.
- 02:55 SAST: Tokyo Fix. USD/JPY can spike. Range-trading setups need cleaner stops here.
- Sunday 23:00 SAST (or 00:00 in winter): Weekly open. Carry trade setups roll. Thin liquidity, wide spreads — execute carefully or wait for Monday.
The trader who reads the clock first and the chart second has a structural edge over the trader who does the reverse.
Trading Terms You’ll See Here
-
Forex Market Hours
The 24-hour-by-five-day window when the global forex market is open. Runs from Sunday 23:00 SAST to Friday 23:00 SAST, divided into four overlapping session zones.
-
South African Standard Time (SAST)
South Africa's time zone, UTC+2, fixed year-round with no daylight saving. The reference clock South African forex traders use to convert global session times.
-
Daily Rollover
The moment around 23:00 SAST when brokers credit or debit overnight swap fees on open positions. Spreads can widen briefly during the rollover window.
-
Session Overlap
A window when two forex sessions are open at the same time. The London to New York overlap from 14:00 to 17:00 SAST is the most liquid window of the global day.
-
Weekend Gap
The price difference between Friday 23:00 SAST close and Sunday 23:00 SAST open. Weekend news (geopolitical, central-bank statements) can create sharp gaps when the market reopens.
The Pulse of the Forex Day
Markets do not move at the same rate from 23:00 Sunday to 23:00 Friday. They pulse. Sydney opens quietly. Tokyo lifts liquidity. London floods it. New York peaks. New York closes and the cycle restarts.
For South African traders, the gift is that this pulse runs through your daylight hours. You do not need to wake up at 02:00 to trade forex. You can hit the London open with your morning coffee, ride the New York open through your afternoon, and clock off when the overlap closes.
The traders who beat the market are not the ones who trade every hour. They are the ones who know which hours matter and show up for those.
So the real question is not when the forex market opens. It is which hours of it you are willing to own.
