Probabilities

Scenarios

Scenario	Probability	Trigger	Market impact
H1Infrastructure war continues	60%	The front stays largely static and both sides keep up strikes on energy infrastructure.	Russian product exports stay low and Ukraine's grid enters winter fragile.
H2Mutual pause	20%	A mutual pause in strikes on energy infrastructure is agreed.	Russian export capacity recovers and Ukraine's grid gets relief.
H3Front in motion	20%	Ukraine's Lyman offensive widens or Russia launches a major new offensive.	Territorial change accelerates; losses and attack intensity increase.

Tactical frictiontemporary · eases over time

Winter calendar weeks
4/5
The impact of grid attacks grows with the start of the heating season.

Repairs to struck refineries and ports take weeks.
Waivers and sanctions enforcement months
