Global Economic Outlook 2026: Supply Shocks, Fragmentation, and the Strategic Imperatives for the Global South

Executive Summary

The 2026 midyear global economic outlook reveals a world economy increasingly constrained by supply-side disruptions, geopolitical conflict and policy-induced fragmentation. Global growth is projected to ease from 3.4% in 2025 to 2.9% in 2026, before recovering to 3.2% in 2027. This deceleration is not merely cyclical but reflects a structural shift toward a more expensive, less efficient and more regionally divided global economy.

For the Global South, the stakes are particularly high. Slower growth in advanced economies, elevated uncertainty and shifting investment patterns could reduce access to development finance, complicate trade diversification and heighten external vulnerabilities. Yet the same dynamics—especially the rapid build-out of AI infrastructure and the reconfiguration of global supply chains—offer openings for countries that pursue deliberate industrial, digital and regional strategies.

This article provides a development-focused reading of the 2026 midyear outlook, examining its implications for emerging markets, South-South cooperation, industrialization, infrastructure investment and long-term economic transformation.

Introduction

In June 2026, EY-Parthenon released its midyear global economic outlook, warning that the global economy is entering a new paradigm defined by layered supply shocks. These shocks include geopolitical conflict, tariffs, industrial policy interventions, energy security concerns, demographic constraints and uneven technology diffusion. The report notes that these forces are raising the cost of growth, reducing efficiency and gradually weighing on medium-term potential output, even as headline activity remains resilient.

For developing countries, the external environment has become more complex. While the Global South has demonstrated remarkable resilience in the face of successive crises, the cumulative burden of trade restrictions, fragmented financial systems and rising protectionism may disproportionately affect countries with limited fiscal space and weaker institutional buffers. At the same time, the global push toward digitalization and artificial intelligence creates a new competitive landscape, with both risks of marginalization and opportunities for leapfrogging.

Background & Context

The global economy has been tested by a series of shocks over the past several years: the pandemic, Russia’s invasion of Ukraine, inflation surges, aggressive monetary tightening and now the Middle East conflict. According to the EY-Parthenon outlook, before the most recent conflict, the drag from tariffs and trade fragmentation had been partially offset by robust AI-related investment, supportive financial conditions and policy easing across several major economies. But the conflict introduced a fresh supply shock through energy prices, commodity markets, shipping routes and financial conditions.

The report emphasizes that the recent wave of tariffs has not triggered a collapse in global trade, thanks to carve-outs, partial rollbacks, corporate hedging and supply-chain reconfiguration. Nevertheless, trade restrictions, export controls and industrial policy are reshaping investment flows, raising operating costs and accelerating regionalization, particularly in semiconductors, energy and critical minerals.

This is the context in which the Global South must navigate its development agenda. Emerging economies face a more fragmented global economy, with implications for export-led growth models, access to technology and the availability of financing for infrastructure and the energy transition.

Main Analysis

A meaningful but non-recessionary slowdown

The EY-Parthenon outlook projects global growth of 2.9% in 2026, down from 3.4% in 2025 and from an earlier December 2025 forecast of 3.1%. A modest recovery to 3.2% is expected in 2027. This is a slowdown, not a slump, but it is occurring against a backdrop of high uncertainty and structural pressures.

For the Global South, these numbers imply a less favorable external demand environment. Many developing economies depend on exports of goods, services and commodities to advanced economies. If growth in the United States, Europe and Japan remains subdued, demand for exports from emerging markets will be dampened, although some countries with strong intra-regional trade links may be less affected.

Regional bifurcation

The advanced economies are experiencing diverging fortunes. The United States remains resilient, supported by affluent consumers, AI-fueled capital investment and elevated asset valuations. Productivity gains from AI are concentrated in the US, giving it a competitive edge. In contrast, the euro area faces softer growth as the Middle East conflict weighs on real incomes, sentiment and external demand, while Japan’s recovery remains modest due to demographics and weak external demand.

This bifurcation also extends to the Global South. Countries with stronger domestic markets, digital infrastructure and industrial capacity are better positioned to weather global headwinds. Those heavily dependent on commodity exports or vulnerable to energy price spikes face greater risks. For example, net energy importers in South Asia and parts of Africa may see their trade balances deteriorate, while energy exporters in the Middle East and Latin America could benefit from higher prices.

Inflation and monetary policy divergence

The EY outlook highlights rising inflation pressures from energy costs and tariffs. Central banks in advanced economies are maintaining a cautious stance, with some still battling to bring inflation durably to target. This has implications for global interest rates and financial conditions. For emerging markets, higher-for-longer rates in advanced economies can lead to capital outflows, currency depreciation and tighter external financing conditions.

Many emerging market central banks, having learned from past crises, have adopted more credible monetary frameworks. This provides some buffer, but external constraints remain significant. Development finance will be more expensive and harder to access for many developing countries, straining budgets and limiting investments in education, health and infrastructure.

Trade fragmentation and supply chain reconfiguration

The report notes that tariffs and industrial policy are accelerating regionalization of supply chains. This is a double-edged sword for the Global South. On one hand, shifting supply chains may open opportunities for new manufacturing hubs in countries like Vietnam, India, Mexico and Morocco. On the other hand, the rise of friend-shoring and near-shoring could marginalize countries unable to meet infrastructure, skill or regulatory standards.

For the Global South, the key is to position itself as a reliable and competitive link in regional value chains. This requires investment in logistics, digital connectivity, access to predictable energy, and institutional reforms to improve the business environment.

AI investment: a game-changer with obstacles

Artificial intelligence is emerging as a major driver of investment and productivity. However, the EY outlook warns that AI-related investment is creating bottlenecks in energy, semiconductors, data centers and other inputs. For the Global South, this presents several challenges and opportunities. The region risks being a passive consumer of AI technologies developed elsewhere, exacerbating digital divides. Yet, there is also potential for using AI to leapfrog in agriculture, healthcare, education, and public service delivery.

Several developing countries are establishing data centers, digital identities and AI strategies. The cost and energy requirements of AI are significant, requiring substantial infrastructure investment. For many low-income countries, this is a daunting prospect. Regional cooperation and South-South knowledge exchange will be crucial to help share costs and build capacities.

Development Impact

Economic development and industrialization

The global slowdown and fragmentation could complicate industrialization efforts in the Global South. Export-led manufacturing may face higher tariffs and nontariff barriers in key markets. However, the reconfiguration of global supply chains presents an opportunity for developing countries to attract foreign direct investment in higher-value manufacturing. Countries that have invested in infrastructure, skills and governance will be better positioned to benefit.

Employment and technology adoption

AI and automation pose risks to low-skill manufacturing jobs, but also create new roles in digital services, software, and maintenance of advanced technologies. The net employment impact depends on the pace of adoption and the development of complementary skills. For the Global South, investing in education and vocational training is critical. Technology adoption, especially mobile-based financial services, has already transformed financial inclusion, and further diffusion of digital technologies could accelerate productivity growth.

Infrastructure and regional trade

The global shift toward regional value chains raises the importance of intra-regional infrastructure. The African Continental Free Trade Area (AfCFTA), ASEAN economic integration, and other regional agreements gain new significance as countries seek to deepen South-South trade. Infrastructure gaps remain a critical barrier; investment in transport corridors, energy grids and digital networks will be essential.

Foreign direct investment and innovation ecosystems

Global competition for FDI is intensifying, with advanced economies providing incentives to reshore or friend-shore production. The Global South must respond with a clear investment case: market access, stable policies, skilled labour and improved infrastructure. Innovation ecosystems require more than just technology; they need financing, research institutions and entrepreneurship. Development banks and multilateral institutions have a role in crowding-in private investment.

Food security and climate resilience

The supply shock world, particularly energy price spikes, affects food production costs – fertilizer, transport, and irrigation. Climate change amplifies these pressures. The EY outlook does not directly address agriculture, but the link between energy and food is clear. For the Global South, investing in climate-resilient agriculture and renewable energy is both a strategic necessity and a development imperative.

Financial inclusion and institutional capacity

Digital public infrastructure can support financial inclusion, as demonstrated by India’s UPI and similar systems elsewhere. The global push toward digitalization provides a window for low-income countries to build inclusive financial systems. Institutional capacity—both regulatory and administrative—remains a bottleneck. Strengthening local institutions is essential for absorbing external shocks and implementing development plans.

Global South Perspective

The implications of the 2026 outlook vary by region.

• Africa: Many African economies face high debt service costs, climate vulnerability and commodity dependence. A global slowdown could reduce demand for raw materials, but also encourages diversification. The AfCFTA and regional infrastructure projects (e.g., in transport and energy) offer a path toward resilience. Partnerships with emerging economies, especially China and India, are already reshaping trade and investment patterns.
• Asia: South Asia and Southeast Asia are at the heart of supply chain reconfiguration. India and Vietnam are benefiting from manufacturing shifts, but need to upgrade skills and infrastructure to sustain growth. Central Asia has potential in energy and transcontinental corridors.
• Latin America: Latin America has rich natural resources and a growing tech ecosystem. However, political instability and fiscal constraints remain. The energy transition positions the region as a provider of critical minerals, green hydrogen and renewable energy. Regional integration, such as Mercosur modernization, could enhance bargaining power.
• Middle East: Energy exporters at times gain from higher oil prices, but face long-term demand uncertainty. Investment in AI and digital diversification is already notable in places like the Gulf states. For the broader region, resolving conflict remains essential for stability.
• Pacific developing economies: Small island nations are especially vulnerable to climate shocks and commodity price volatility. They require concessional finance and technology transfer for adaptation.

South-South cooperation is becoming a strategic force for sharing development lessons. The BRICS expansion, the New Development Bank, and the Asian Infrastructure Investment Bank provide alternative sources of finance and policy knowledge. The Global South must not merely adapt to a fragmented world; it must actively shape new governance frameworks for trade, technology and finance.

Future Outlook

The next 5–10 years will be defined by how the Global South responds to a world of supply shocks and digital transformation. Several trends are likely:

• Artificial Intelligence and digital economy: AI will become central to productivity growth. Developing countries must invest in digital infrastructure, data governance and human capital. Regional AI hubs could reduce dependence on the US and China.
• Regional integration: The Global South will look inward toward regional value chains. The African Continental Free Trade Area, the Regional Comprehensive Economic Partnership, and other agreements will become more important as global fragmentation deepens.
• Climate adaptation and energy transition: Green industrialization offers a pathway for the Global South to leapfrog carbon-intensive development paths. Solar, wind and hydrogen investments can improve energy security while generating new export opportunities.
• Development finance: Traditional sources will be insufficient. Blended finance, local currency debt markets and multilateral reform will be needed to mobilize trillions for the Sustainable Development Goals. The Global South should push for reforms in global financial architecture, including reallocation of Special Drawing Rights and expanded lending capacity of development banks.
• Global governance: The Global South is likely to demand a stronger voice in institutions such as the IMF, World Bank and WTO. The growing influence of BRICS and other groupings could lead to a more pluralistic global order.

Conclusion

The 2026 global economic outlook is not about a single shock but a systemic shift toward a supply-shock world. Growth will be slower, costs higher and fragmentation deeper. For the Global South, this is both a threat and an opportunity. Countries that take strategic measures—investing in digital infrastructure, regional cooperation, industrial capacity, and climate resilience—can turn these global realignments into developmental gains. The Global South cannot control global headwinds, but it can chart a course of structural transformation that positions it as a resilient, innovative and increasingly self-reliant part of the world economy.
