European gas and power markets, once a niche corner of global energy trading, are in for a major change this week: Hours will more than double to 21 from 10, ending the narrow daytime window that has been the norm for years.
The permanent expansion, announced several months ago, comes at a particularly volatile time as war in the Middle East drives sharp price swings. Even after the recent ceasefire announcement, contracts for European gas remain almost 40% above pre-conflict levels. With traders glued to their screens, preparations for the new 21-hour trading day have lagged. Some firms are taking a wait-and-see approach on whether to hire more staff or reorganise their desks.
Yet despite the turbulence, many energy traders say the change is a logical next step for a market transformed by Russia’s invasion of Ukraine. Europe’s break from a single dominant energy supplier pushed it into the global liquefied national gas market, exposing prices to disruptions far beyond the region. At the same time, the growth of renewables has added further swings in power generation, feeding through to gas demand.
These developments have made European gas and power more attractive to global traders. What was once a fundamentals-driven market, focused on weather, storage and pipeline flows, now features more complex strategies, including cross-market hedging between Europe’s gas benchmark and US Henry Hub.
Options activity has picked up from near non-existent levels, while spread trading has grown amid persistent supply risks and hedge funds have driven volumes higher.
To many, aligning trading hours with US and Asian benchmarks widens investor access and better reflects a market with expanding reach and relevance. The market will open at 5:50 am Singapore time on Monday, making it the first major energy contract to begin the trading week. The new 21-hour day is “an advantage for global players,” said Marco Saalfrank, head of continental Europe merchant trading at Swiss-based Axpo Holding AG. “If something happens in the market that affects prices, they can react immediately.”
For traders on the ground in Europe, the longer window is set to reshape how they work and live.
Until now, the routine has been relatively structured: Traders log on before markets open at 8 am in Amsterdam, assess fundamentals such as flows and storage, scan weather and geopolitical developments, and take positions at roughly the same time. When the hours expand, that rhythm will fragment across time zones, with participants dipping in and out of the market much like they do in oil.
Whether that’s a net positive depends on whom you ask. In interviews with European traders, the mood was mixed, with concerns that a 21-hour market could erode a work-life balance already rare in the industry.
A Swiss trading desk head said he worries about missing his children’s bedtime as market-moving headlines from US President Donald Trump on Iran often land after 6 pm in Europe. A London-based trader said unreliable train Wi-Fi could make the evening commute more stressful, while a utility trader joked he would expect a pay rise if longer hours become the norm. Some plan to set alarms overnight to monitor markets.
Operational questions are also mounting. A Singapore-based LNG trader said expanded hours will require far more cross-time-zone coordination, complicating decision-making. Others question whether liquidity will keep pace or simply spread volatility over a longer trading day.
The changes don’t have “obvious benefits to localised trading demographics,” said Tim Partridge, head of trading and risk management at LG Energy Group in the UK. One London-based trader at a small fund said his team is largely Europe-based, leaving him unable to rely on handovers to US or Asian desks.
Across the Atlantic, the reaction has been more positive. A trader at a cross-commodity hedge fund in Chicago said the move is a boon for paper traders, allowing algorithms to train during periods when liquidity is thinner. There is also a view that longer trading hours could help smooth some of the sharp price swings seen in recent weeks.
Compared with Europe, US power markets have long traded across a much wider window.
A Miami-based portfolio manager, who asked not to be identified, trades oil and US natural gas alongside European energy futures and said punishing hours are part of the job. He is used to 14-hour shifts and often works from home on Sundays.
