Russia-Ukraine: The Long Conflict and Its Market Architecture
The Russia-Ukraine conflict is now in its fourth year, and it has developed a market architecture that is distinct from its early-stage dynamics. The acute shock of February 2022 the initial market dislocation, the commodity price spike, the rapid redesign of European energy imports has been partially absorbed. European gas infrastructure has been restructured; Russia has reoriented its export flows eastward; the world has adjusted to a bifurcated energy market.
What has not been priced because it is inherently non-priceable as a point estimate is the resolution path. The conflict's duration and ultimate settlement terms have profound implications for European energy costs, reconstruction investment flows, and the political economy of European defence spending. Several scenarios bracket the range:
Scenario A: Negotiated ceasefire (moderate probability). US diplomatic pressure, combined with Ukrainian military resource constraints and Russian cost accumulation, produces a frozen conflict agreement. Ukraine retains sovereignty over most of its territory, Russia retains some occupied areas, and international security guarantees are constructed. This scenario unlocks a significant Ukraine reconstruction investment programme estimated at $400-500 billion in which European financial institutions, infrastructure funds, and multinational corporations would be primary participants.
Scenario B: Continued military stalemate (higher probability, nearer term). The most likely scenario for 2026 itself is continued stalemate Russian territorial control over occupied areas, ongoing Ukrainian offensive operations, and diplomatic activity that produces process but not resolution. This scenario maintains the current geopolitical risk premium at approximately its current level. European defence spending continues to accelerate. Energy prices remain at elevated (though not crisis-level) baseline.
Scenario C: Significant escalation. A scenario in which Russian strikes on NATO territory, Polish or Baltic state involvement, or a breakdown in ceasefire negotiations triggers formal NATO engagement. This is assessed as a low-probability event by most risk frameworks, but the market impact would be severe energy price spike, equity selloff, flight to US dollar and gold, forced reassessment of European asset premiums.
The persistent relevance of the Ukraine conflict for energy markets is worth specific attention. Russia remains a significant global supplier of oil (approximately 10% of global supply), natural gas, and agricultural commodities. Any significant escalation in strikes on energy infrastructure which both sides have periodically targeted creates potential supply disruptions that oil markets would immediately reprice.
The Middle East: The Strait of Hormuz as the World's Most Important Chokepoint
The Iran-Israel-US dynamic has escalated materially in early 2026. US and Israeli military operations that expanded in late February and continued through March have created a market response the S&P 500 fell approximately 7% below its prior peak before stabilising, while international equities declined 8-12%. The critical variable for markets is not the military engagement itself but the impact on the Strait of Hormuz, through which approximately 20% of global oil supplies and a significant portion of global LNG exports transit daily.
A full closure of the Strait of Hormuz even a temporary one lasting days would produce an oil price spike of a magnitude that would be immediately inflationary. Goldman Sachs and other energy research desks model a Strait disruption scenario at $120-150/barrel, compared to current prices in the $70-80 range. This is not a prediction; it is a stress scenario that illustrates the tail exposure in energy markets.
The direct economic transmission of an oil shock of this magnitude runs as follows: energy costs rise immediately for transport, manufacturing, and home heating; food prices follow with a 6-12 week lag (food production and distribution are energy-intensive); core inflation rises; central banks face the impossible choice between tightening (to address inflation) and cutting (to address growth); and the stagflationary dynamic higher inflation, lower growth produces the asset class configuration most hostile to multi-asset portfolios.
The agricultural dimension of the Middle East conflict deserves more attention than it typically receives. The conflict's impact on fertiliser supply both through sanctions on Russian potash and nitrogen production, and through potential disruptions to shipping routes used for fertiliser transport creates a food price vulnerability that disproportionately affects lower-income economies and populations.
Taiwan: The Extreme Tail That Analytical Frameworks Struggle to Hold
Taiwan presents the most analytically challenging geopolitical risk in the global investment landscape. The challenge is not that the risk is misunderstood the basic parameters are well-known. It is that the scenario is so consequential, so multi-dimensional, and so discontinuous from the current state that conventional risk frameworks which extrapolate from historical distributions have limited usefulness.
A military conflict over Taiwan whether a blockade, a missile campaign, or an amphibious invasion attempt would involve the world's leading semiconductor manufacturer (TSMC, which alone accounts for approximately 90% of the world's most advanced chip production capacity), the world's two largest economies in direct military confrontation, and a supply chain disruption across electronics, automotive, defence, and consumer technology that would dwarf the COVID-19 supply chain shock.
The market response to such a scenario would be severe and multi-year. Supply of advanced chips would be disrupted for a minimum of 12-24 months under optimistic assumptions; under more pessimistic ones, the productive capacity at risk might not be fully replaced for five years or more.
The investment community's typical response to this scenario is to treat it as a tail risk low probability, extreme impact and to hold it lightly in portfolio construction, perhaps through a modest overweight to defence-related assets or through maintaining some gold allocation as a crisis hedge. This approach is not irrational, but it does involve a choice to accept the correlation risk that comes from having no effective hedge to the scenario.
Integrating Geopolitical Risk: A Framework for Portfolio Construction
The practical challenge for institutional investors is translating this scenario analysis into actionable portfolio adjustments. Several principles guide a rigorous approach:
Distinguish between priced and unpriced risk. Many geopolitical risks are partially reflected in current asset prices. European equities trade at a meaningful discount to US equivalents some of which reflects geopolitical risk premium. EM assets with Gulf or Eastern European exposure carry risk premia that embed some geopolitical concern. The investment question is not whether geopolitical risk exists, but whether it is appropriately priced relative to the investor's own assessment.
Identify assets with natural geopolitical hedging properties. In a world of elevated geopolitical risk, certain asset classes have historically functioned as partial hedges: gold (crisis store of value), energy commodities (supply shock beneficiaries), defence sector equities (spending acceleration), and USD (safe haven in acute risk-off episodes). These are not reliable hedges across all scenarios but they can reduce overall portfolio correlation to geopolitical tail scenarios.
Macro hedge funds as diversifiers. Discretionary macro hedge funds have been the best-performing hedge fund category in 2025, partly because their ability to express directional views across currencies, rates, and commodities is well-suited to a macro environment dominated by geopolitical variables. The negative correlation of macro strategies to equity portfolios during drawdowns makes them an unusual and valuable diversifier.
Maintain liquidity. In environments of elevated geopolitical uncertainty, the ability to rebalance, add to positions, or exit is worth more than in stable environments. Portfolios that have sacrificed liquidity for yield through high allocations to illiquid alternatives or lock-up vehicles face real optionality costs in a world where geopolitical discontinuities can arrive with limited lead time.
Conclusion: Living With a Higher Geopolitical Baseline
The post-Cold War period roughly 1991 to 2022 was characterised by an unusually low and declining level of geopolitical risk. That period has ended. The new baseline involves more active conflicts, more fragmented global governance, and more frequent use of economic instruments for strategic purposes.
This new baseline does not require abandoning risk assets or adopting a bunker mentality. It requires treating geopolitical risk as a persistent portfolio input embedding it in scenario analysis, stress testing portfolios against energy shock and trade disruption scenarios, and maintaining diversification across assets whose geopolitical sensitivities differ. It is, in the final analysis, the same discipline that has always been required of serious long-horizon investors: understanding the risk you are taking, ensuring you are being compensated for it, and structuring your portfolio to survive the tail without requiring perfect timing to exit.
