How the Iran War Exposes the Fragility of the Global Development Model

Over the past thirty years, the global development narrative has often rested on a default assumption: trade routes remain largely open, energy supplies can continue, and even when shocks occur, they are only short-term disturbances. In reality, this assumption has never been a law, yet it has long been treated as one. The Iran war has made this fragility impossible to ignore—it reminds the international community that the global development system is not built on a solid foundation, but on the assumption that a “normal state” will continue to exist.

The key significance of this war lies not only in changes to the regional security landscape, but in how it cuts through multiple links in the development chain: energy prices, fertilizer supply, food production, industrial costs, financing conditions, and the risk of poverty reduction being reversed. In other words, war is not merely an event confined to the geopolitical level; it also constitutes a stress test of the global development model.

When “Efficiency First” Meets “Shocks as the New Normal”

The development framework of the post-Cold War era generally favored maximum efficiency: supply chains were extended as much as possible to cut costs, energy dependence on the global market was maximized, capital was allowed to flow as freely as possible, and countries were encouraged to focus on comparative advantage. In stable environments, this model did improve growth efficiency and helped many countries expand exports, create jobs, and improve infrastructure.

The problem is that this model often treats resilience as a secondary variable. As long as maritime routes are not blocked, energy supplies do not fluctuate sharply, and financial markets remain liquid, the system appears to be functioning. Once a shock becomes a “correlated hit” across geopolitics, energy, logistics, and finance, fragility quickly emerges.

The reason the Iran war matters for global development is precisely that it is not a single-point shock, but one that can be amplified through multiple channels: shipping insurance, energy transport, fertilizer raw materials, industrial inputs, food prices, and fiscal pressure all interact with one another. For many developing countries, this means the risk is no longer simply a rise in a single price, but the squeezing of development budgets, the forced sidelining of social protection, and even setbacks in poverty reduction.

Fertilizer, Food, and Poverty: Where Development Fragility Appears First

There is a fact in development studies that is often underestimated: food security depends not only on land and weather, but also on whether energy, fertilizer, and the international trade system remain stable. The reference material notes that Brazil is one of the world’s largest fertilizer importers and that its agricultural production is highly dependent on external inputs; meanwhile, a significant share of global urea trade passes through the Strait of Hormuz. In this way, shifts in the Middle East are no longer just news for the energy market—they directly affect agricultural costs in South America and, in turn, the affordability of food in Africa, the Middle East, and South Asia.

This is a classic chain reaction in global development:

• Upstream: energy and transport risks;
• Midstream: rising fertilizer and agricultural input costs;
• Downstream: food price volatility and declining household purchasing power;
• Ultimately: increased risks of malnutrition, poverty rebound, and fiscal support burdens.

The poverty-reversal risk highlighted by the United Nations is precisely the social outcome of this chain reaction. It shows that poverty reduction is not a one-time achievement, but an institutional result that requires continuous maintenance. As long as external shocks are superimposed on vulnerable countries, the improvements accumulated over many years can be rapidly eroded.

Why ESG Becomes More Important at This Moment

The impact of the Iran war on ESG is not just a matter of “rising energy prices.” In fact, it is pushing ESG from corporate disclosure and investment screening to the central role of risk governance and supply-chain resilience.

On the environmental dimension, the tension between energy security and the low-carbon transition has become more pronounced. Many countries, while advancing the energy transition, originally hoped to reduce dependence on a single energy source through market mechanisms. But when war raises the costs of energy, transportation, and raw materials, transition projects, green infrastructure, and public finances may all come under pressure. This may lead some countries to temporarily revert to a policy hierarchy of “securing supply first, transitioning later.”

On the social dimension, food prices, employment stability, and public service spending will be hit on two fronts. For low-income households, food and energy are the two most sensitive expenditures; for governments, subsidies, relief, and debt servicing may all rise at the same time. The “S” in ESG is not an abstract concept, but whether a country can protect people’s livelihoods in the face of external shocks.

On the governance dimension, this war once again proves that risk disclosure cannot stop at the corporate annual report level. What really matters is how countries, financial institutions, and multilateral organizations identify systemic risks, and how they establish cross-border early warning, emergency financing, and policy coordination mechanisms. If ESG lacks a global governance perspective, it will degenerate into a local compliance tool and fail to respond to structural vulnerabilities in the development system.

Development Finance Is Shifting from “Expansion” to “Defense”

The reference material mentions that the International Monetary Fund’s assessment of global growth has become more cautious and emphasizes “time-limited, targeted” responses for the most vulnerable groups. This change has important policy implications: it shows that international development finance is shifting from being expansion-oriented to being defense- and buffer-oriented.

For many emerging markets and developing countries, the real pressure is not just slower growth, but the simultaneous rise in financing costs and decline in foreign exchange earnings. Countries that import energy and food will face greater strain between the current account, fiscal deficits, and exchange-rate stability. If debt pressure is added on top of that, the resources governments can use for education, healthcare, infrastructure, and social protection will be continually squeezed.

Therefore, today’s development finance agenda is no longer just about “how much can be borrowed,” but about:

1. Whether countercyclical funding can be obtained at lower cost; 2. Whether debt can be restructured quickly when external shocks occur; 3. Whether short-term stabilization measures can be combined with long-term transition investment; 4. Whether food, energy, and public services can be provided with sustained buffers.

This is also why multilateral financial institutions, regional development banks, and South-South cooperation instruments are becoming increasingly important. No single country can bear systemic risk alone; the value of cooperation mechanisms is rising.## The Global South Is Not a “Marginal Variable,” but a Key Part of Systemic Stability

If the global development narrative in the past was more often framed from the perspective of the industrial systems of Europe and the United States, today’s reality is different. Population growth, food demand, energy transition, digital diffusion, and urbanization are increasingly concentrated in the Global South.

This means that the Global South is no longer merely an object that “needs help,” but a core region for global growth, resource allocation, and risk transmission. Connections among the Middle East, South Asia, sub-Saharan Africa, Latin America, and Southeast Asia are becoming tighter through trade, energy, food, and capital markets. War in one region may, through pricing and financing chains, affect public budgets and household livelihoods on another continent.

From a policy perspective, this requires an adjustment in the logic of international cooperation:

• from single-point aid to building systemic resilience;
• from project-oriented approaches to risk governance;
• from short-cycle performance to long-term capacity building;
• from fragmented responses to cross-regional coordination.

In other words, the Global South is not an appendage of global governance, but the main arena for testing the effectiveness of global governance.

The Role of International Organizations: From Crisis Relief to Structural Rebuilding

Such shocks once again push international organizations back to center stage, but their role should no longer be understood merely as providers of post-crisis funding. More importantly, can they help member states rebuild development resilience?

The UN system focuses on poverty, food, and humanitarian consequences; the International Monetary Fund focuses on macroeconomic stability and payment capacity; while the World Bank and regional development banks have long-term tools in infrastructure, public services, energy, and institutional capacity. Truly effective global governance is not one institution solving all problems alone, but these institutions achieving coordination under the same risk scenario.

This also means that future international cooperation must place greater emphasis on:

• supply chain vulnerability assessments;
• strategic reserves and mutual assistance mechanisms;
• resilience of agricultural inputs and food systems;
• balancing renewable energy with local energy security;
• rapid financing channels for low-income countries.

If international organizations continue to follow the more fragmented policy logic of the past, it will be difficult to respond to today’s comprehensive shocks that cut across sectors, regions, and markets.

Long-Term Trend: Development Models Are Shifting from “Globalized Growth” to “Risk-Constrained Growth”

What the Iran war reveals is not a short-term crisis in a particular country, but a repricing of the global development order. Future development models may no longer pursue the lowest cost and highest liquidity as the sole goals; instead, they will place greater emphasis on redundancy, backup, dispersion, and local capacity.

This implies several long-term trends:

• energy structures will place greater emphasis on diversification and reserve capacity;
• agricultural systems will place greater emphasis on fertilizer, irrigation, and climate adaptability;
• industrial policy will place greater emphasis on the security of key raw materials and intermediate goods;
• fiscal policy will place greater emphasis on countercyclical room for maneuver;
• ESG investing will focus more on real resilience, rather than merely disclosure scores.For developing countries, this is both pressure and an opportunity to redefine competitiveness. Countries that can more quickly build resilience in public services, energy substitution capacity, food security mechanisms, and digital governance capacity will enjoy greater long-term advantages in the new global environment.

Conclusion: Development has never been only an economic issue

The reason the Iran war deserves close global attention from the development field is that it once again proves this: development gains are not automatically durable, and global growth is not inherently sustainable. As long as the international system remains dependent on a few critical corridors, a few energy nodes, and highly externalized supply chains, any regional conflict can evolve into a global setback for development.

Therefore, the focus in the future should not be only on “restoring growth,” but on “rebuilding resilience.” This includes more reliable development financing, more flexible international cooperation, more robust food and energy systems, and stronger public service capacity to withstand external shocks.

The global development system is entering a new stage: efficiency still matters, but resilience, inclusiveness, and governance capacity are becoming decisive variables. Whoever can sustain public well-being amid uncertainty will be closer to the next stage of development competitiveness.
