When Is the Asian Forex Session? Trading Hours Explained
Understand the Asian Forex session: its key hours, market dynamics, and how global overlaps influence currency trading activity.
The foreign exchange (forex) market operates continuously, 24 hours a day, five days a week, due to its global nature and varying time zones. This uninterrupted operation is structured around distinct trading sessions, reflecting the business hours of major financial hubs worldwide. Understanding these sessions helps participants identify periods of heightened activity, varying liquidity levels, and specific market behaviors that influence trading decisions.
Global Forex Trading Sessions
The forex market’s continuous nature is maintained by four primary trading sessions: Sydney, Tokyo (Asian), London (European), and New York (North American). These sessions seamlessly transition, allowing trading activity around the clock from Monday morning in Asia until Friday evening in North America. Each session plays a role in the global market, with unique characteristics influenced by economic events and market participants in its region. The Sydney session marks the trading week’s beginning, followed by the Tokyo session, which overlaps with the opening of the European market in London. The New York session then overlaps with London before concluding the trading day, leading back to Sydney.
The Asian Forex Session
The Asian forex session begins with the opening of markets in Sydney, Australia, and encompasses financial centers like Tokyo, Japan; Singapore; and Hong Kong. The broader Asian session runs from approximately 10:00 PM Coordinated Universal Time (UTC) to 9:00 AM UTC. For traders in the Eastern Standard Time (EST) zone, this corresponds to 5:00 PM EST to 4:00 AM EST. The Tokyo market, a component of this session, operates from 12:00 AM UTC to 9:00 AM UTC, or 7:00 PM EST to 4:00 AM EST.
Liquidity during the Asian session is generally lower compared to the more active European and North American sessions. This can lead to more range-bound price movements, where currency pairs trade within a narrower price band. Currency pairs involving the Japanese Yen (JPY), Australian Dollar (AUD), and New Zealand Dollar (NZD) often experience higher volatility due to economic data releases from these regions. Economic reports, such as Japan’s GDP figures or Australia’s employment data, can impact currency prices and set the tone for the trading day.
Overlapping Trading Hours
Forex session overlaps occur when two major financial markets are simultaneously open, leading to increased trading activity. These overlaps contribute to higher liquidity and heightened volatility, as more market participants are active. The most significant overlap involving the Asian session occurs with the start of the European (London) session. The London market opens around 7:00 AM UTC or 8:00 AM UTC, while the Tokyo session is active until 9:00 AM UTC.
This period, from 7:00 AM UTC to 9:00 AM UTC, sees a convergence of traders from both Asian and European financial centers. The increased volume can result in larger price movements and tighter bid-ask spreads, making it an attractive time for traders seeking dynamic market conditions. While the London-New York overlap is often cited as the most active, the Tokyo-London overlap is an important period, particularly for currency pairs actively traded in both regions, such as EUR/JPY or GBP/JPY. A minor overlap also exists between the Sydney session and the closing hours of the New York session, providing a brief transition before the full Asian trading day commences.
