Strategic Harvest: Food Security and Investment Strategy in a Fragmenting Global Order

Executive Summary

The weakening of the US-led international order is introducing profound new sources of risk into investment portfolios, risks that many traditional asset allocation frameworks are fundamentally ill-equipped to assess or manage. Through the lens of food security—a domain where the breakdown of stable, market-driven systems has become particularly visible—we can observe how geopolitical fragmentation, strategic rivalry, and the weaponization of trade are reshaping the risk-return dynamics across multiple asset classes and geographies. The global agricultural system, long organized around efficiency and comparative advantage, now operates increasingly as a strategic arena where policy interventions override market signals, supply chain vulnerabilities multiply, and historical correlations dissolve. For investors, this transformation demands a reassessment of portfolio construction principles. Active management is no longer optional for those seeking alpha but essential for those seeking to identify, measure, and navigate the non-linear risks that passive strategies cannot accommodate. The imperative is not merely portfolio optimization but portfolio resilience in an environment where tail risks proliferate and traditional diversification offers diminishing protection.

The Retreat of the US-Led Global Order

The international architecture that facilitated agricultural trade and cooperation for the past seventy years is experiencing unprecedented strain, with cascading implications for investment portfolios exposed to agricultural assets, commodity markets, and regions dependent on food imports. Structural changes in international relations and governance reflect the rise of multipolar competition, with China’s economic ascendance, Russia’s assertive posture, and the emergence of regional powers challenging the primacy of Western-led institutions. The erosion of multilateral trade frameworks has accelerated, as seen in the proliferation of bilateral agreements and the increasing use of sanctions as a tool of statecraft. By 2024, state-based conflicts reached historic levels, with 61 active conflicts marking the highest number recorded since 1946³, fundamentally disrupting the stable geopolitical environment that agricultural markets—and the investment portfolios built upon them—long took for granted.

The impact on agricultural trade flows and input supply chains has been substantial and far-reaching, introducing systematic risks for which historical models cannot account. Trade weaponization and export restrictions have become commonplace, with approximately 75 export restrictions on agrifood products imposed in 2023 and disproportionately affecting food and feed⁴. Strategic competition over fertilizer and energy resources intensified as nations recognized these inputs as leverage points in geopolitical contests. The Russia-Ukraine conflict provided a stark illustration of these dynamics, resulting in what has been characterized as the greatest military-related increase in global food insecurity in the last century⁵ and severely disrupting national and global food supplies, while simultaneously creating unexpected volatility in asset classes seemingly distant from agricultural markets.

Recent disruptions in grain, fertilizer, and energy markets underscore the transition from rules-based to power-based resource allocation, a shift with profound implications for how investors must assess country risk, sector exposure, and portfolio diversification. In 2024, more than 295 million people across 53 countries6 and territories experienced acute levels of hunger, an increase of 13.7 million from 2023⁶, with famine confirmed in Sudan for the first time since 2020⁷. These humanitarian crises translate directly into political instability, sovereign risk, and investment losses in affected regions and their trading partners. The global NPK fertilizer supply chain has proved highly susceptible to disruption, with more than 57% of nitrogen exports coming from just five sources (the European Union, China, Russia, Qatar, and Saudi Arabia), over 77% of phosphorus exports from five sources (China, Russia, the EU, Morocco, and the United States)⁸, and more than 89% of potassium exports from five suppliers (Canada, Russia, Belarus, Morocco, and the United States). China’s severe export restrictions on nitrogen and phosphate to secure domestic supply, combined with ongoing sanctions on Russia and Belarus, elevated price volatility across all three nutrient streams throughout 2024 and 2025⁹.

From Efficiency to Strategic Contestation

The transformation of food production from commodity to strategic asset represents one of the most significant shifts in the global economy, and through the agricultural sector we can observe broader trends that are reshaping risk across investment portfolios. Food security has been explicitly reframed as a national security priority, with the Canadian Prime Minister Mark Carney capturing this new reality at the 2026 World Economic Forum by declaring that “we are in the midst of a rupture, not a transition” and that countries must develop strategic autonomy in energy, food, critical minerals, and finance, noting that “a country that can’t feed itself, fuel itself or defend itself has few options.”¹⁰ Government intervention and industrial policy have expanded dramatically, with nations implementing subsidies, production quotas, and strategic reserves to ensure domestic supply security. The reshoring and nearshoring of production capacity has accelerated as countries seek to reduce dependence on potentially unreliable foreign suppliers.

Input supply chains have emerged as critical geopolitical leverage points, but the concentration of NPK fertilizer production is not merely a matter of geographic distribution—it reflects fundamental geological constraints that make supply diversification far more difficult than conventional trade analysis suggests. Phosphate rock deposits of commercial quality are geologically rare, concentrated in Morocco (which controls approximately 70% of global reserves)¹¹, China, and a handful of other locations. Potash deposits similarly reflect ancient geological processes, with economically viable reserves limited to specific sedimentary basins in Canada, Russia, Belarus, and a few other regions. Even nitrogen—while technically producible anywhere with access to air and energy—requires massive capital investment in ammonia synthesis plants and abundant natural gas feedstock, creating economic concentration that mirrors geological constraints for phosphorus and potassium. These geological realities mean that supply chain diversification faces physical limits that policy interventions cannot easily overcome.

Critically, no single country produces all three components of NPK fertilizers in sufficient quantities to ensure full agricultural self-sufficiency, a reality that introduces systemic vulnerability across the entire global food system rather than creating simple regional “winners and losers.” The United States, though a major agricultural producer, depends heavily on Canadian potash and imported phosphates. China, despite massive fertilizer production capacity, imports potassium and increasingly restricts exports to prioritize domestic food security. Russia possesses vast potash reserves but depends on global trade networks to monetize them. Even resource-rich nations face vulnerabilities throughout the supply chain—from mining and processing infrastructure to transportation networks and financial settlement systems. Most significantly, the apparent increasing reluctance of the United States to play its traditional role as the prime guarantor of the US-led international rules-based order (on which global shipping security is based) introduces fundamental uncertainty into the maritime trade routes through which the vast majority of fertilizer moves.¹² In an environment where safe passage can no longer be assumed, disruptions to any segment of the NPK supply chain cascade rapidly across global agricultural production, affecting food availability, commodity prices, and investment portfolios everywhere, regardless of regional resource endowments.

The implications for investors are profound. The notion that investors can simply allocate capital to “food-secure” regions and thereby insulate themselves from agricultural volatility fundamentally misunderstands the nature of systemic risk in a fragmented world. Supply chain disruptions affect global agricultural output, not merely regional production. When phosphate shipments from Morocco face interruptions, when potash railroads from Saskatchewan experience delays, when nitrogen plants in Qatar halt operations, or when maritime insurance costs spike due to geopolitical tensions, the effects ripple through global food systems regardless of where individual agricultural assets are located. Portfolio resilience in this environment requires not just regional selection but rather the analytical capacity to identify, measure, and respond to supply chain vulnerabilities for which traditional asset allocation frameworks were not designed.

Geopolitical and Policy-Driven Volatility

New sources of systematic risk in agricultural markets have proliferated as policy considerations increasingly override market fundamentals, introducing volatility patterns that challenge conventional portfolio construction and risk management techniques. Policy uncertainty and regulatory divergence across jurisdictions create compliance challenges and investment risks, as nations pursue conflicting objectives in food security, climate policy, and trade relations. Sanctions regimes and trade restrictions have become commonplace tools of statecraft, with the weaponization of agricultural trade evident in actions ranging from export bans to targeted tariffs. Climate policy and its differential regional impact introduce additional complexity, as carbon pricing, renewable mandates, and sustainability standards impose varying costs on producers depending on their geographic location and production methods. For investors, these policy-driven risks exhibit non-linear characteristics that historical risk measures cannot anticipate.

The breaking of correlation structures across asset classes represents a shot across the bow to traditional portfolio theory and diversification strategies.¹³ Geopolitical risks increasingly dominate price formation for food commodities.¹⁴ Currency and sovereign risk implications have grown more complex, as food security concerns could influence central bank policy, fiscal spending, and government bond yields in ways that backward-facing macroeconomic models might struggle to capture. The practical consequence for investors is that diversification benefits calculated using historical data have become unreliable guides to future risk, potentially leaving portfolios exposed.

Increased tail risk and reduced predictability characterize the current environment, with event-driven shocks ranging from conflicts and export bans to climate events capable of triggering abrupt market dislocations that overwhelm conventional hedging strategies. The Sudan crisis of 2024-2025, which left half of the country’s 25.6 million people experiencing acute food insecurity, exemplifies how rapidly conditions can deteriorate when conflict, economic collapse, and supply chain disruptions converge. Reduced market depth and liquidity during stress periods amplify price movements and limit investors’ ability to adjust positions, while the concentration of NPK fertilizer trade means that disruptions in any single source can trigger global shortages that affect multiple asset classes simultaneously. The inadequacy of historical models and backward-looking analysis has become increasingly apparent, as the regime change in agricultural markets means that past risk measures provide unreliable guides to future behavior. Value-at-Risk calculations, stress tests based on historical scenarios, and optimization models built on decades of price data all suffer from the same fundamental flaw: they assume that the statistical properties of the past offer meaningful guidance about the future, an assumption that geopolitical fragmentation has rendered problematic.

Investment Implications: Risk-Return Dynamics

Portfolio construction challenges in the new environment require a fundamental rethinking of established principles, moving beyond optimization toward resilience as dual objectives. Traditional diversification benefits are under pressure as correlations between asset classes shift unpredictably and historical relationships break down under the influence of policy interventions and geopolitical events. Specific opportunity and risk areas demand careful analysis and selective positioning, but the capacity to identify these opportunities in real-time distinguishes successful portfolio management from passive exposure to sector benchmarks.

Emerging risk factors for traditional portfolios require heightened attention and active management, as exposure to these risks cannot be mechanically hedged through passive allocation adjustments. For instance, exposure to import-dependent regions carries significant downside risk as these areas face persistent food insecurity and price volatility, with 2024 seeing acute hunger reach 295 million people across 53 countries.¹⁵ However, the belief that simply reducing exposure to these regions eliminates agricultural risk reflects a fundamental misunderstanding of systemic vulnerability. Single-source supply chain dependencies create concentration risk that materializes rapidly when geopolitical events disrupt established trade flows, as demonstrated by US agricultural exports falling from $174.1 billion in 2024 to an estimated $173 billion in 2025 with projections of $169 billion for 2026—the lowest level since 2021 —driven primarily by the collapse of soybean and sorghum shipments to China after the US imposed higher tariffs^{16 17}. Policy and regulatory risk concentration has intensified as governments intervene more aggressively in agricultural markets, with actions ranging from export bans to price controls capable of destroying value in affected sectors within days or weeks.

Traditional valuation metrics based on historical cash flows and commodity price relationships provide increasingly unreliable guides as policy interventions distort market signals and geopolitical risk premiums widen. The challenge for investors is assessing risks that have little historical precedent and limited market price discovery—a challenge that passive strategies cannot address and quantitative models trained on historical data might dramatically misjudge.

The Case for Active Management and Strategic Flexibility

Passive strategies are increasingly challenged for navigating the current environment, not because they fail to capture market beta but because the concept of a stable, representative market portfolio has become incoherent in a fragmenting global order. Index composition biases toward legacy structures fail to capture the rapid sectoral and geographic shifts reshaping agricultural markets and the broader investment landscape. Index weightings reflect historical production and trade patterns that bear diminishing resemblance to emerging realities, exposing passive investors to declining sectors and vulnerable regions while missing opportunities in ascendant areas. The inability to respond to rapid policy shifts represents a fundamental limitation of passive approaches, as changes in trade policy, export restrictions, and industrial policy can materially alter the profitability and risk profile of entire sectors within weeks or months. Geographic and sectoral rigidity inherent in index-based strategies prevents reallocation in response to evolving geopolitical conditions, technological disruptions, or climate-related shifts in production geography

Active management emerges as an essential capability—not only for generating alpha through superior security selection but for assessing and responding to non-linear risks that passive strategies cannot accommodate. The distinction is critical. In a world of stable correlations and mean-reverting markets, passive strategies offer efficient exposure to systematic risk factors at low cost. In a fragmenting world where correlations break down, tail risks proliferate, and policy interventions dominate price formation, active management becomes necessary to maintain portfolio resilience and mitigate catastrophic drawdowns. Dynamic regional allocation enables portfolio managers to shift exposure in response to evolving supply chain vulnerabilities, policy developments, and geopolitical alignments, but the objective is not solely about maximizing returns but calibrating exposure to risks that backward-looking frameworks may not be able to properly model. Tactical exposure to policy-driven opportunities allows investors to benefit from government support for strategic sectors, subsidies for technology adoption, or trade agreements that open new markets. Risk management through flexible positioning becomes crucial as tail risks proliferate and historical correlations break down, requiring the ability to adjust portfolio composition rapidly in response to emerging threats or dislocations that automated rebalancing rules cannot address.

The premium on information, analysis, and adaptability has never been higher than through the lens of agricultural markets, and through this domain we can observe the broader requirements for portfolio management in a fragmented world. Underwriting risk in this sector, for instance, requires granular, region-specific underwriting that accounts for water reliability, diversified cropping systems, infrastructure quality, and policy stability, but more fundamentally it requires analytical frameworks for assessing supply chain vulnerabilities, geopolitical risks, and policy trajectories that quantitative models cannot capture. Satellite-derived analytics and agricultural technology tools provide enhanced visibility into production trends, resource constraints, and operational efficiency, creating information advantages for investors willing to deploy these capabilities, but technology alone cannot substitute for the judgment required to assess non-linear risks in real-time. The complexity of evaluating geological constraints on NPK fertilizer supply, maritime security risks in a post-Pax Americana environment, and the cascading effects of policy interventions across interconnected supply chains demands expertise and analytical frameworks that passive strategies may not provide and conventional risk models might underestimate.

Active management in this context does not mean frequent trading or attempts to time market cycles. It means maintaining the analytical capability to identify risks that have no historical precedent, assess vulnerabilities that market prices do not reflect, and adjust portfolio exposures in response to developments that automated rebalancing rules cannot process. Food security, viewed through the lens of geopolitical fragmentation, offers critical insights into these types of systemic risks. It means abandoning the illusion that passive exposure to broad market indices offers meaningful diversification in an environment where the assumptions underlying modern portfolio theory no longer hold. Most importantly, it means accepting that portfolio resilience—the capacity to withstand tail risks and preserve capital through regime changes—has become a more critical objective than portfolio optimization in a world where the statistical properties of asset returns exhibit fundamental instability.
