Sanctions, infrastructure disruption and electricity markets: pricing geopolitical risk

The last few years have given European power markets an unwelcome real-world lesson in how geopolitical shocks feed through into electricity prices. Cuts to Russian pipeline gas, the damage to Nord Stream, and wave after wave of energy sanctions have all left their mark on how European gas and power markets are priced and structured.

This article looks at how sanctions and infrastructure disruption work their way through power markets: the transmission mechanism, the pricing effects, and what they mean for risk management on a trading desk.

How do sanctions affect energy markets?

Sanctions on energy exports are meant to restrict fuel supply from a particular source. What they actually do to prices depends on how large that source is, how fast buyers can find alternatives, and whether the sanctions apply broadly or leave carve-outs for energy trade.

The sanctions on Russian energy following the 2022 invasion of Ukraine are the clearest recent example of sanctions risk in European energy markets. They didn't stop Russian gas flows overnight; pipeline gas kept moving through some routes for a long time afterwards. But they created enough doubt about future supply to force a complete rethink of European energy security.

That rethink is what actually moved prices. Utilities and trading houses rushed to refill storage, bid aggressively for LNG cargoes, and pushed to cut their reliance on Russian gas through new contracts and infrastructure spending. The scramble to prepare for a possible supply loss pushed prices up well before any gas actually stopped flowing.

This is typical of how sanctions episodes play out in energy markets: prices reflect the probability of disruption, not just the eventual outcome. As the odds of a serious supply shock rise, prices start moving before the disruption itself happens. Traders who understand this dynamic can position ahead of the physical impact rather than reacting once it's already visible in the data.

Infrastructure disruption is a different risk

Physical damage to energy infrastructure behaves differently from sanctions. It tends to be sudden, unambiguous in its immediate effect, and much harder to work around through alternative sourcing.

Nord Stream in September 2022 is the clearest example of infrastructure disruption in European gas markets. Taking that pipeline out didn't itself cut gas flows much further, since flows had already dropped sharply by that point. What it did was close off a structural supply option for Europe, possibly for good. Markets weren't just reacting to the immediate gas balance; they were pricing in what the loss meant for Europe's supply security over the long run.

Infrastructure damage feeds through into power markets mainly by cutting gas supply and pushing prices up. It can also cut regions off from each other, widen the gap between regional power prices, and create local shortages if interconnectors are hit. Damage to storage or regasification facilities leaves the whole system more exposed to swings in demand and renewable output.

How quickly infrastructure can be repaired matters a great deal for pricing. Assets that can be fixed within weeks have a very different effect on the forward curve than infrastructure that's gone for years, or permanently. The market's view on how likely and how fast recovery will be shapes the entire curve. A disruption seen as temporary tends to hit near-term prices hard while leaving the far end of the curve more or less untouched. A disruption seen as permanent shifts the whole curve upward.

Regional exposure to sanctions and infrastructure risk

Sanctions and infrastructure disruption don't hit all European power markets the same way. Exposure depends on which supply routes and infrastructure are affected, and how easily each market can find alternative supply.

Central and Eastern European markets that relied heavily on Russian pipeline gas through specific transit routes were hit hardest. When those routes were curtailed, there simply weren't as many affordable alternatives close at hand. Markets further west, with better access to LNG import terminals and more diverse supply, were better insulated, though still affected through gas price links across the wider European network.

Electricity markets tend to follow gas market exposure, but the generation mix complicates the picture. Markets where gas plants set the marginal price for most hours felt the impact directly. Markets with a larger share of nuclear, hydro or coal were partly shielded, though not completely, since interconnector flows carry price signals across borders regardless of local generation mix.

Some countries also moved faster than others on infrastructure. Germany's rapid rollout of floating LNG storage and regasification units is the standout example of a country cutting its exposure quickly, in contrast with markets slowed down by planning or permitting delays.

Forward curves vs spot prices during a supply shock

The pricing effects of sanctions and infrastructure disruption don't land evenly across the curve, and spot markets react quite differently from forward markets.

Spot and near-term prices move fast. When pipeline flows drop or infrastructure goes offline, day-ahead gas and power prices adjust within hours as the market absorbs the new supply picture. Intraday markets can be particularly volatile right after a disruption, as traders reposition and system operators manage balancing in real time.

Forward curves show what the market expects about how long a disruption will last and what it means structurally. A disruption viewed as temporary tends to spike short-term prices without moving longer-dated contracts much. One viewed as permanent or long-lasting pushes the entire curve higher, signalling that the market expects tighter supply for good. Shifts between these two views, as new information comes in about the chances of recovery, can drive real volatility in forward power prices.

Risk premiums also tend to climb across the curve during periods of heightened sanctions risk or infrastructure uncertainty. Even contracts well beyond the immediate crisis trade higher, as the market prices in the chance of further deterioration. These premiums can stick around long after the initial crisis has passed, reflecting a genuine reassessment of tail risk in the supply outlook.

Trading implications of sanctions and infrastructure disruption

Sanctions and infrastructure disruption create trading dynamics that don't look much like the usual drivers of power price volatility.

1. Speed matters most in the initial move

The first reaction to a sanctions announcement or an infrastructure incident is usually sharp and fast, and positions already aligned with the direction of the shock benefit the most. Risk frameworks built for rapid position adjustment, rather than slow approval chains, cope better with these episodes.

2. Temporary versus permanent disruption is the key judgement call

The shape of the forward curve after a disruption tells you what the market currently believes about recovery. Traders who can form their own view on recovery timing, drawing on infrastructure knowledge, geopolitical analysis and supply chain understanding, can spot mispricing against the market consensus.

3. Cross-market spreads tend to widen

Sanctions and infrastructure disruption often hit specific routes or regions harder than others, so regional gas and power price divergence can grow sharply, opening up spread-trading opportunities for desks with cross-border capability.

4. Alternative supply flows become an important signal

During a disruption, how fast alternative supply gets mobilised, whether that's LNG cargoes being diverted, storage being drawn down, or interconnector flows shifting, tells you a lot about how tight the market is likely to stay. Watching these flows closely improves the quality of positioning decisions.

Risk management for sanctions and infrastructure risk

Managing exposure to sanctions and infrastructure disruption means stretching standard risk frameworks to cover events that are sudden, potentially permanent, and poorly captured by historical price data.

Scenario analysis is the most useful practical tool here. Stress tests should include the sudden loss of a major supply route, a sharp escalation in the scope of sanctions, or damage to a key interconnector or storage site. The aim isn't to predict which scenario will happen, but to understand how the portfolio would hold up if it did, and to spot any concentrations that would cause unacceptable losses.

Liquidity deserves particular attention. In the immediate aftermath of a major disruption, bid-ask spreads widen, market depth thins out, and adjusting positions gets a lot more expensive. Portfolios heavily concentrated in products that become illiquid under stress are far more exposed than those that keep flexibility across a range of instruments and time horizons.

As covered in our blog on structural volatility in power markets, the current environment produces a wider range of outcomes than historical models would suggest. Sanctions and infrastructure disruption are among the tail events driving that wider range. Risk limits calibrated to the pre-2021 world may well understate the true risk of the current one, and are worth revisiting.

Conclusion

Sanctions and infrastructure disruption sit at the sharp end of geopolitical risk in energy markets. They happen suddenly, they can be irreversible, and they can move power and gas prices in ways that catch models off guard.

For trading desks, the answer isn't trying to predict when the next disruption will land; that's not a solvable problem. It's building frameworks that can absorb the shock when it comes, through scenario planning, careful liquidity management, the ability to adjust positions quickly, and enough analytical depth to tell a temporary shock apart from a permanent structural shift.
