The forex market operates 24 hours a day from Sunday evening to Friday evening. However, trading activity is not evenly distributed throughout the day. Liquidity and volatility change as the major financial centres in Asia, Europe and North America open and close.
Understanding forex session times can help traders identify when their preferred currency pairs are most active. EUR/USD, for example, normally attracts stronger participation during the London and New York sessions, while AUD/JPY is often more active during Asian trading hours.
This guide explains the main forex trading sessions, the most actively traded currency pairs and how session overlaps can affect spreads, liquidity and price movement.
Major Currency Pairs
The major currency pairs are the most heavily traded pairs in the forex market. Each one contains the US dollar alongside another major global currency.
The seven pairs commonly recognised as forex majors are:
Currency pair Currencies represented Common name
EUR/USD Euro and US dollar Euro-dollar
USD/JPY US dollar and Japanese yen Dollar-yen
GBP/USD British pound and US dollar Cable
USD/CHF US dollar and Swiss franc Dollar-Swiss
AUD/USD Australian dollar and US dollar Aussie
USD/CAD US dollar and Canadian dollar Loonie
NZD/USD New Zealand dollar and US dollar Kiwi
Major currency pairs typically attract high trading volumes because they represent some of the world’s largest economies and most widely used currencies.
Higher participation often produces deeper liquidity and tighter spreads than those available on less frequently traded pairs. However, spreads can still widen during major news releases, periods of market stress and quieter trading hours.
What moves the major currency pairs?
Currency prices respond to changes in economic expectations. Some of the most influential factors include:
Central bank interest-rate decisions
Inflation reports
Employment data
Economic growth
Government policy
Commodity prices
Political developments
Market risk sentiment
Each pair also has its own important drivers. USD/CAD can react to changes in oil prices because Canada is a major crude oil exporter. AUD/USD may respond to commodity demand and developments in China, one of Australia’s largest trading partners.
USD/JPY is particularly sensitive to interest-rate differences between the United States and Japan. EUR/USD and GBP/USD, meanwhile, often move sharply around policy decisions from the Federal Reserve, European Central Bank and Bank of England.
What are minor and exotic currency pairs?
Minor currency pairs, also called crosses, combine two major currencies without the US dollar. Examples include EUR/GBP, EUR/JPY and GBP/JPY.
Exotic pairs combine a major currency with the currency of a smaller or emerging economy. They may offer large price movements, but they often have lower liquidity and wider spreads.
For beginners, major currency pairs can be easier to monitor because they generally have more available market analysis, greater liquidity and lower average trading costs.
Forex Session Times
The four main forex trading sessions are Sydney, Tokyo, London and New York. Together, they create a continuous trading week as activity moves from one financial centre to another.
The following table shows the commonly used forex session times in Coordinated Universal Time:
Forex session Standard-time hours Daylight-saving hours
Sydney 21:00 to 06:00 UTC 20:00 to 05:00 UTC
Tokyo 00:00 to 09:00 UTC 00:00 to 09:00 UTC
London 08:00 to 17:00 UTC 07:00 to 16:00 UTC
New York 13:00 to 22:00 UTC 12:00 to 21:00 UTC
These times can shift because London, New York and Sydney observe daylight saving at different points in the year. Tokyo does not observe daylight saving time. Traders should therefore confirm the current session schedule instead of assuming that every market opens at the same UTC time throughout the year.
The global forex trading week generally begins when the Sydney session opens on Monday morning in Australia, which is Sunday evening in New York. It continues until the New York session closes on Friday.
Although currency prices can move at any time during the trading week, activity usually increases around major market openings, economic announcements and session overlaps.
London Session
The London session is one of the busiest periods in the forex market. London’s position between the Asian and North American trading days allows it to interact with both regions.
The standard London session forex time is:
08:00 to 17:00 UTC during the UK winter
07:00 to 16:00 UTC during British Summer Time
Liquidity often increases when London opens because European banks, investment firms, companies and institutional traders become active.
This rise in participation can produce tighter spreads and stronger price movement, particularly in European currency pairs.
Popular pairs during the London session include:
EUR/USD
GBP/USD
EUR/GBP
GBP/JPY
EUR/JPY
USD/CHF
The first few hours of the session can be active as traders react to developments from Asia and prepare for European economic reports. Important releases may include UK inflation, employment and gross domestic product data. Eurozone inflation, economic growth and European Central Bank decisions can also affect activity.
The London session does not guarantee strong market movement every day. Prices may remain quiet when the economic calendar is light or when traders are waiting for an important US announcement later in the day.
New York Session
The New York session brings US and Canadian market participants into the forex market. It is closely watched because the US dollar appears in every major currency pair.
The standard New York session forex time is:
13:00 to 22:00 UTC during US standard time
12:00 to 21:00 UTC during US daylight saving time
The session can become particularly active when influential US economic data is released. Reports such as inflation, employment, retail sales and economic growth can quickly change expectations for Federal Reserve policy.
Frequently traded pairs during the New York session include:
EUR/USD
GBP/USD
USD/JPY
USD/CAD
USD/CHF
AUD/USD
USD/CAD may receive additional attention during this period because both the United States and Canada are active. Canadian employment, inflation and Bank of Canada decisions can move the pair alongside US data.
Trading activity may slow later in the New York afternoon, particularly after European markets have closed. However, unexpected political developments, central bank comments and changes in US bond yields can still produce significant price movements.
Asian Session
The Asian forex session is led by activity in Sydney and Tokyo, with participation from other financial centres including Singapore and Hong Kong.
The commonly followed Asian session forex time runs from approximately 21:00 UTC, when Sydney opens during standard time, until 09:00 UTC, when Tokyo closes.
Tokyo itself operates from:
00:00 to 09:00 UTC throughout the year
Japan does not observe daylight saving time, so the Tokyo schedule remains unchanged. Sydney’s UTC hours move when Australia changes its clocks.
Currency pairs that often attract attention during the Asian session include:
USD/JPY
AUD/USD
NZD/USD
AUD/JPY
NZD/JPY
AUD/NZD
The session can react strongly to economic data from Japan, Australia, New Zealand and China. Chinese economic reports are particularly important because China is a major trading partner for Australia and New Zealand.
The Asian session is sometimes described as quieter than London or New York, but that description does not apply to every currency pair. AUD, NZD and JPY pairs can move sharply following central bank decisions, employment reports, inflation data or unexpected political news.
Lower activity in some European and North American pairs may lead to narrower trading ranges. However, thinner liquidity can also contribute to sudden price changes when important news arrives.
When Do Forex Trading Sessions Overlap?
A session overlap occurs when two major financial centres are active at the same time. These periods often attract more trading volume because participants from both regions are buying and selling currencies.
London and New York overlap
The London and New York overlap is generally the busiest part of the forex trading day.
It normally occurs between:
13:00 and 17:00 UTC during standard-time alignment
12:00 and 16:00 UTC when both regions observe daylight saving time
The precise schedule can briefly differ because the United States and United Kingdom change their clocks on different dates.
EUR/USD and GBP/USD often experience higher liquidity during this overlap. US economic announcements are also frequently released while London remains open, creating the potential for sharp price movements.
Sydney and Tokyo overlap
Sydney and Tokyo overlap during the earlier part of the Asian trading day. AUD, NZD and JPY pairs may attract more attention during this period.
The overlap can be influenced by economic news from Australia, New Zealand, Japan and China.
Tokyo and London overlap
Tokyo and London overlap only briefly. The limited crossover means it is normally less active than the London and New York overlap.
Even so, the transition can matter for pairs such as EUR/JPY and GBP/JPY as European traders respond to movements that developed during the Asian session.
What Is the Best Forex Session to Trade?
There is no single best forex session for every trader. The most suitable period depends on the currency pair, trading strategy, risk tolerance and availability of the trader.
A trader following EUR/USD may prefer the London session or the London and New York overlap. Someone trading AUD/JPY may find more relevant activity during Asian hours.
Different strategies may also favour different conditions:
Day traders may seek active periods with higher liquidity and frequent price movements.
Breakout traders may focus on major session openings or economic announcements.
Range traders may prefer quieter conditions when prices remain between established support and resistance levels.
Swing traders may use session times to improve entries but hold positions for several days.
Higher volatility is not automatically better. Rapid markets can create opportunities, but they can also produce larger losses, slippage and false breakouts. The best session is one that suits the trader’s tested strategy and risk controls.
How Session Times Affect Spreads and Volatility
Liquidity describes how easily a currency can be bought or sold without causing a large price change. When more traders are active, liquidity generally improves.
High-liquidity periods can offer:
Tighter bid-ask spreads
Faster order execution
More consistent pricing
Greater trading activity
Quiet periods may produce wider spreads and less predictable execution. This is particularly important around the weekly market opening, major holidays and the interval between the New York close and stronger Asian participation. Volatility measures how much and how quickly prices move. It often rises after important economic releases or unexpected news.
A highly liquid market can still be volatile. EUR/USD, for example, may retain deep liquidity while moving sharply after a Federal Reserve announcement.
Traders should consider both conditions. Liquidity affects the ease and cost of entering a trade, while volatility affects how quickly the position can gain or lose value.
How to Choose the Right Currency Pair and Trading Session
Start by choosing a small number of currency pairs rather than trying to follow the entire market.
Consider the following:
When can you trade? Choose pairs that are active during the hours available to you.
Which economies do you understand? Following a pair becomes easier when you understand its central banks and economic drivers.
What are the trading costs? Compare spreads, commissions and overnight financing charges.
How volatile is the pair? Some currency pairs move more sharply than others.
Are major announcements scheduled? Check the economic calendar before opening a position.
Does the pair suit your strategy? A method designed for active markets may perform differently during quieter sessions.
A trading plan should also define the maximum amount at risk, the conditions required for entry and the point at which the position will be closed.
Conclusion
Understanding major currency pairs and forex session times helps traders identify when different parts of the currency market are most active.
The London session is important for European currencies, the New York session is heavily influenced by US data and the Federal Reserve, while the Asian session is especially relevant for the Japanese yen, Australian dollar and New Zealand dollar.
Session overlaps can create stronger liquidity and price movement, but timing alone does not make a trade successful. Currency selection, market analysis, trading costs and risk management remain essential parts of every trading decision.
