Trading power markets through geopolitical crises: a risk framework

This blog sets out a practical framework for navigating geopolitical crises in power markets, covering preparation, in-crisis management and reassessment once the immediate stress has passed.

Why crises require a different approach

The main difficulty in trading during a geopolitical crisis is that the usual tools become least dependable precisely when they are most required. This doesn't mean the toolkit is flawed; rather, it is an inherent aspect of crisis situations that honest frameworks must recognise.

Quantitative models are built on historical relationships. Geopolitical crises, by definition, introduce discontinuities - sudden changes in supply configuration, policy environment or market structure that lack direct historical precedent. A model trained on European power market data from the past decade did not include the full removal of Russian pipeline gas as a scenario. It cannot reliably price the consequences of an event it has never encountered.

Human judgment encounters specific challenges in crises. Rapidly evolving information, financial pressures and limited time create environments where cognitive biases (such as recency bias, overconfidence and anchoring to pre-crisis prices) are likely to influence decisions. The most effective traders and risk managers during crises are usually those who have prepared their responses beforehand, rather than those who react quickest in the moment.

The practical implication is that crisis management is primarily a matter of preparation. Desks that have worked through crisis scenarios, defined decision frameworks and established clear responsibilities before a crisis hits are better placed to act effectively when one arrives than those that attempt to design their response in real time.

Preparation: building a crisis-ready framework

Effective preparation for geopolitical crises involves several distinct elements, each of which needs to be in place before stress materialises.

1. Scenario analysis should be done in advance

The scenarios that matter most during a crisis are those that have been thought through before the crisis begins. Stress testing that covers major supply disruptions, escalation of sanctions, infrastructure damage and compound weather-geopolitical events gives trading desks a reference point when real events unfold. The goal is not to predict the specific crisis but to have already considered how the portfolio would perform under a range of severe conditions - and to have identified in advance what actions would be appropriate.

2. Pre-defined decision rules and escalation processes

During a fast-moving crisis, the time available to deliberate over responses is limited. Decision frameworks that define in advance when positions should be reduced, when risk limits should be tightened and when human oversight should override automated systems enable faster, more consistent responses. As explored in our blog on governance and risk control for algorithmic power trading, clear escalation processes are particularly important when automated systems may generate unreliable signals in crisis conditions.

3. Liquidity assessment across the portfolio

This involves identifying which positions and products are most vulnerable to becoming illiquid during stress periods. Typically, products that are liquid under normal conditions, such as certain intraday contracts, cross-border spreads and longer-dated forward positions, may become hard to trade quickly during market stress. By knowing in advance which segments pose the highest liquidity risk, one can manage these risks more effectively when market conditions worsen.

4. Monitoring infrastructure that covers geopolitical signals

Standard energy market data feeds are necessary but not sufficient during a geopolitical crisis. Storage levels, LNG cargo flows, pipeline nominations, diplomatic developments and infrastructure news all carry relevant information. Desks that have already built these inputs into their information flow, rather than scrambling to find them when a crisis breaks, can identify developing stress earlier and act with more lead time.

In-crisis management

During a geopolitical crisis, priorities move from analysis to immediate management. While questions about what is happening, why and how long it will last stay important, they must be balanced with urgent needs for risk mitigation and position management.

The first priority is stabilisation. Before assessing opportunities, a trading desk needs to understand its current exposure and ensure that positions remain within acceptable risk parameters in light of changed market conditions. A crisis that moves prices sharply in one direction may have transformed a well-balanced portfolio into a concentrated directional bet, even without any active decision. Reviewing exposure quickly and accurately is the foundation of everything else.

The second priority is distinguishing signal from noise. During crises, vast, often contradictory or incorrect information floods in. Refraining from reacting to every piece of data is crucial. Simple analysis—monitoring key physical indicators of supply-demand and filtering out market rumours - is most valuable.

The third priority is execution discipline. Strong views and worsening liquidity pressure can lead to aggressive actions, but during crises, such actions can be costly and counterproductive, pushing prices further against trades and limiting liquidity for adjustments. Patience and discipline, even with high conviction, usually lead to better results than urgency.

Managing model risk during crises

As discussed in our blog on model risk in power trading, automated systems are most likely to fail when market dynamics move outside their historical range. Geopolitical crises are precisely the conditions where that failure risk is highest.

The practical approach is not to turn off all automated systems, as some still provide value during crises, especially execution algorithms that handle order placement effectively. Instead, it is important to clearly specify which model outputs remain trustworthy and which should be viewed with scepticism.

Signal quality monitoring becomes critical. If a model's signals are based on relationships disrupted by the crisis - for example, a gas-to-power price relationship that has broken down because price caps are distorting one side of the spread - continuing to trade on those signals will produce poor outcomes. Identifying which signals are still working and which are not is more valuable than either switching everything off or continuing to trade as normal.

Human override capability needs to be genuinely available, not merely theoretical. Governance frameworks that require lengthy approval processes for overrides are less useful in a fast-moving crisis than frameworks in which traders and risk managers can act quickly within defined parameters. The balance between systematic discipline and human flexibility needs to be calibrated for crisis conditions, not just normal market operations.

With information overload a genuine risk during geopolitical stress, it helps to have a short list of physical and market indicators that provide the most reliable signals about how conditions are evolving.

These indicators do not fully capture a crisis, but they offer a solid physical perspective on whether supply and demand are tightening or easing - factors that ultimately influence prices. Basing analysis on physical fundamentals rather than market sentiment or price trends generally leads to more dependable assessments during times of high uncertainty.

After the crisis: reassessment and adaptation

After the immediate tension of a geopolitical crisis eases, there's often a strong urge to resume normal activities swiftly. However, avoiding this impulse and instead dedicating time to a thorough reassessment is one of the most beneficial actions a trading desk can undertake.

The essential questions are whether the crisis was a temporary disruption or a lasting structural change and whether the risk framework worked as intended or showed gaps. A crisis that exposes weaknesses in models, liquidity issues, or governance failures, especially those unforeseen, provides valuable insights. These insights should inform changes in how the desk operates, rather than being seen as just a stressful period to endure and forget.

Post-crisis reassessment should cover model performance: which signals worked during the crisis and which did not; liquidity management where execution costs were higher than expected and why; scenario coverage (whether the actual crisis was within the range of scenarios that had been prepared for); and governance (whether decision frameworks and escalation processes functioned as intended under pressure).

Each crisis that passes without a full reassessment is a missed opportunity to improve the framework for the next one.

Conclusion

Trading power markets during geopolitical crises is not a problem that can be solved by better models or faster systems alone. It requires preparation, judgment, disciplined execution and the organisational capability to act coherently under pressure.

The series covers various frameworks, including understanding LNG market transmission and power prices, managing sanctions and infrastructure disruptions, accounting for weather-related tail risks and assessing the effects of government intervention. All these factors influence how a trading desk prepares for crises. Those who have pre-emptively considered these dynamics are in a stronger position than those facing them for the first time during rapid market movements.

Geopolitical risk in European power markets is not going away. The structural forces driving it: the fragmentation of the global energy supply, the use of energy as a tool of statecraft and the growing weather dependence of the generation mix, are intensifying rather than easing. Building the frameworks to navigate that environment is not a one-off exercise. It is an ongoing part of what it means to trade European power markets well.
