Forex Trading Sessions in South Africa (SAST): Best Trading Hours & USDZAR Guide
BY TIOmarkets
|March 3, 2026The forex market operates 24 hours a day from Monday to Friday, but not all hours are equal.
Trading activity, liquidity, and spread conditions vary significantly depending on which financial centres are open at any given time.
For traders and Forex brokers in South Africa, understanding how global sessions align with South African Standard Time (SAST) helps identify when conditions are likely to be most favourable and when to exercise more caution.
This article covers the main forex trading sessions, how they map to SAST, what that means for spread conditions and volatility, and what South African traders should consider when choosing a broker.
The Four Main Forex Trading Sessions
The global forex market is typically divided into four main sessions, named after the financial centres that drive activity during each period: Sydney, Tokyo, London, and New York. Each session has different characteristics in terms of liquidity, volatility, and which currency pairs tend to be most active.
South Africa Standard Time (SAST) is UTC+2 year-round. South Africa does not observe daylight saving time, which means the SAST equivalent of each session remains relatively consistent. However, European and US clocks do change seasonally, which can shift session overlap times by approximately one hour depending on the time of year. The times below are approximate and intended as general reference points.
Sydney Session
The Sydney session is the first to open each week and marks the start of the forex trading day. It tends to be the quietest of the four sessions in terms of overall volume, with activity concentrated in Australian dollar pairs and New Zealand dollar pairs.
For South African traders, this session falls in the early hours of the morning, roughly from around 00:00 to 09:00 SAST. Most South African traders are not active during these hours, and it is generally not considered the most relevant session for those trading major pairs or USDZAR.
Tokyo Session
The Tokyo session overlaps partially with Sydney and brings increased activity in Japanese yen pairs and some Asian currency pairs. Overall volume during the Tokyo session is higher than Sydney but still lower than the European sessions.
In SAST terms, the Tokyo session falls approximately between 01:00 and 10:00. Like the Sydney session, this window falls largely outside standard waking hours for South African traders and tends to see wider spreads on pairs that are less active during Asian hours.
London Session
The London session is the largest and most liquid forex session by trading volume. It covers a significant portion of global daily forex turnover and sees the tightest spreads on major pairs under normal conditions. The London session is when European economic data is released, which can drive short-term volatility on EUR, GBP, and related pairs.
For South African traders, the London session falls approximately between 10:00 and 19:00 SAST. This window aligns well with standard business hours in South Africa, making it one of the most accessible and liquid sessions for local traders. Spreads on major pairs tend to be at their tightest during this period under normal market conditions.
New York Session
The New York session is the second largest by volume and overlaps with the London session for several hours each day. This overlap period is generally considered the most liquid window of the forex trading day, when the largest concentration of transactions occurs across both European and American markets.
In SAST terms, the New York session falls approximately between 15:00 and 00:00. The London-New York overlap, roughly 15:00 to 19:00 SAST, is typically when liquidity peaks and spreads on major pairs are at their most competitive under normal conditions.
The London-New York Overlap: Most Active Window for South African Traders
The overlap between the London and New York sessions is widely regarded as the most active period of the forex trading day. A large proportion of daily forex volume passes through the market during this window, and major pairs such as EURUSD, GBPUSD, and USDJPY tend to see their tightest spreads and most consistent liquidity.
For South African traders, this overlap falls in the mid-to-late afternoon, roughly 15:00 to 19:00 SAST, which is a convenient time to trade. The combination of high liquidity and tighter spreads under normal conditions makes this window generally favourable for strategies that are sensitive to entry costs, such as scalping or short-term trading.
It is worth noting that major US economic data releases, such as Non-Farm Payrolls or CPI figures, fall within the New York session and can cause sharp short-term volatility and spread widening even during otherwise liquid periods. Traders should be aware of scheduled high-impact releases and factor them into their approach.
USDZAR: Trading the South African Rand
USDZAR is the primary currency pair for traders with a specific interest in the South African rand. It measures the value of the US dollar against the South African rand and is one of the more widely traded emerging market currency pairs.
What Drives USDZAR
USDZAR is influenced by a range of factors including commodity prices (South Africa is a significant exporter of gold, platinum, and other metals), domestic economic data, South African Reserve Bank policy decisions, and broader emerging market sentiment. Global risk appetite also plays a significant role: the rand tends to weaken during periods of global risk aversion and strengthen when risk appetite improves.
Because USDZAR is an emerging market pair rather than a major currency pair, it typically carries wider spreads than pairs such as EURUSD or GBPUSD, and liquidity can be thinner outside of peak trading hours.
USDZAR Trading Hours and Specifications
At TIOmarkets, USDZAR is available to trade from Monday 00:00 to Friday 23:55 MT server time (UTC+2). Traders should confirm current server time with TIOmarkets directly as settings may vary. The spread is floating and variable. The standard lot size is USD 100,000 and the minimum trade volume is 0.01 lots (USD 1,000 notional). Leverage is available up to 1:2000 on USDZAR, depending on account type and equity tier, and is available under the MISA entity only. The margin call level is 100% and the stop out level is 30%. Trading conditions vary and traders should confirm applicable conditions, including leverage, directly with TIOmarkets before opening an account.
When Is USDZAR Most Active?
USDZAR tends to see its highest liquidity and tightest spreads during the London session and the London-New York overlap, when both European and US participants are active. South African market hours also coincide with the London session, which means local economic data releases can generate additional activity during this window.
Outside of the London and New York sessions, USDZAR spreads may widen as liquidity thins. Traders focusing on USDZAR should be particularly mindful of spread conditions during the Asian session, when rand liquidity is at its lowest.
How Session Timing Affects Spreads
All spreads at TIOmarkets are variable and sourced from liquidity providers. They tighten under normal conditions when liquidity is high and widen during periods of low liquidity, high volatility, and around major news releases. Orders are executed at the best available market price and may experience positive or negative slippage, particularly during volatile periods.
For South African traders, this means the session you choose to trade in has a direct effect on the spread you are likely to pay at entry. Trading major pairs during the London session or the London-New York overlap gives the best chance of tighter spread conditions under normal circumstances. Trading the same pairs during the Sydney or Tokyo sessions, or immediately before major data releases, carries a higher likelihood of wider spreads.
This is particularly relevant for short-term strategies where the spread represents a significant proportion of the intended price movement. Longer-term traders holding positions for days or weeks are generally less affected by session-specific spread variation, though they should remain aware of overnight swap costs on positions held past the daily rollover.
Broker Considerations for South African Traders
ZAR Base Currency
One practical consideration for South African traders is whether to hold a trading account in ZAR or in a major currency such as USD. TIOmarkets supports ZAR as a base currency on Standard, Raw, and VIP Black accounts, which means deposits, withdrawals, and account balances can be denominated in rand without the need for currency conversion on every transaction.
Holding an account in ZAR removes the currency conversion step on deposits and withdrawals, but it also means that trading results on non-ZAR pairs involve an implicit conversion back to ZAR at the prevailing rate. Traders should consider which base currency suits their situation and confirm available options before opening an account.
ZAR Deposits
TIOmarkets accepts ZAR deposits via debit and credit card. Deposits are free when the minimum deposit amount is met. The minimum deposit is R500 on the Standard account. Bank wire transfer is available for major currencies but ZAR is not listed as a supported wire currency, so card is the primary route for ZAR-denominated deposits. E-wallets (Skrill and Neteller) do not support ZAR. Cryptocurrency deposits are also available as an alternative funding method, subject to availability and any applicable restrictions in your jurisdiction.
Account Types
TIOmarkets offers Standard, Raw, VIP Black, and Nano account types. The Standard account (minimum deposit $20 or currency equivalent, R500 for ZAR accounts) carries spreads from 1.1 pips with no commission and is the entry-level option. The Raw account (minimum deposit $250 or currency equivalent) offers spreads from 0.0 pips with a $6 commission per round turn lot, and may suit traders who are more cost-sensitive and trading at higher volume. The VIP Black account (minimum deposit $1,000 or currency equivalent) offers spreads from 0.3 pips with no commission. Currency equivalent amounts apply for ZAR and other supported base currencies.
