OECD Economic Outlook June 2026: Under Pressure

 The conflict in the Middle East has emerged as the dominant force shaping the global economic outlook in mid-2026. While the world economy initially showed resilience through strong investment in artificial intelligence and easing trade tensions, it is now "under pressure" from severe disruptions to regional shipments and infrastructure.

Core Economic Disruptions

The impacts are primarily driven by damage to energy infrastructure and the near-halt of shipments through the Strait of Hormuz.

• Energy Supply: Global oil supply fell by 13.5% between February and April 2026, with Gulf production alone dropping by 45%. LNG exports from the region, notably from Qatar, have also halted due to production facility damage.
• Commodity Prices: Prices for crude oil, natural gas, sulphur, and fertilisers (like urea) have ratcheted upward.
• Trade and Logistics: Strait of Hormuz transits remain a fraction of pre-conflict levels, leading to severe port congestion in areas like Oman and the Red Sea. Global ocean freight rates have risen approximately 45% above pre-conflict levels.
• Industrial Inputs: The region is a critical source for methanol, ammonia, and helium. Helium is particularly vital for semiconductor manufacturing, meaning disruptions could eventually hinder AI infrastructure development.

Scenario-Based Outlook

Recognizing high uncertainty, the sources present two possible trajectories for the global economy:

1. Time-Limited Disruption Scenario: This assumes energy production and trade return to pre-conflict levels from the third quarter of 2026. Under this path, global GDP growth is projected to slow from 3.4% in 2025 to 2.8% in 2026 before recovering to 3.1% in 2027. Inflation in G20 countries would rise to 4.0% in 2026.
2. Prolonged Disruption Scenario: If disruptions persist into late 2027, global growth could plummet to 2.1% in 2026 and 1.8% in 2027, pushing some economies toward recession. In this case, global inflation would see significant upside pressure, rising by an additional 1.3 percentage points in 2027.

Impact on Specific Regions and Sectors

The burden of the conflict is not distributed evenly:

• Asian Economies: These are among the most exposed due to their heavy reliance on Persian Gulf energy imports. Countries like Thailand, Korea, and India have particularly high direct and indirect exposure.
• Developing Economies: Commodity-importing developing nations face severe risks, as they often lack the fiscal capacity to cushion households against price shocks and have weaker social safety nets.
• Agriculture: Higher fertiliser prices and supply disruptions threaten global crop yields and food security, with grain prices expected to remain higher for longer than the duration of the conflict itself.
• AI and Technology: Prolonged energy shortages would increase data center operating costs—energy accounts for 60% of these costs—and potentially delay large-scale AI infrastructure projects.

Policy Recommendations

The OECD emphasizes that flexible and agile policies are required to ensure stability.

• Fiscal Policy: Governments should provide relief to households and firms, but measures should be temporary and well-targeted to avoid excessive fiscal costs and preserve incentives to reduce energy use.
• Energy Resilience: The crisis underscores the urgent need to diversify energy supplies and improve energy efficiency to "wean" economies off dependency on fossil fuel imports from single chokepoints.
• Monetary Policy: Central banks must remain vigilant; while they may "look through" temporary supply-driven price rises, they must act if inflation expectations become de-anchored or growth weakens substantially.

Recognizing the exceptional uncertainty surrounding the conflict in the Middle East, the June 2026 OECD Economic Outlook frames global projections through two distinct trajectories for the next eighteen months. These scenarios are primarily conditioned on the duration of disruptions to energy production and trade routes in the Persian Gulf.

1. Time-Limited Disruption Scenario (Projections-Based)

This scenario assumes that the disruptions caused by the conflict are significant but relatively short-lived.

• Conflict Resolution: It assumes progress toward a negotiated peace agreement, with energy production and regular shipping routes returning to pre-conflict levels starting in the third quarter of 2026.
• Growth Path: Global GDP growth is projected to moderate from 3.4% in 2025 to 2.8% in 2026, before recovering to 3.1% in 2027.
• Inflation: Consumer price inflation in the G20 is expected to rise to 4.0% in 2026 (up from 3.4% in 2025) before easing to 3.1% in 2027 as energy and food price pressures fade.
• Policy Stance: Central banks are generally expected to keep policy interest rates broadly stable through 2026 before easing slightly in 2027. The fiscal stance remains broadly neutral in most countries during 2026.
• Mitigating Factors: Strong underlying momentum from AI-related investment, resilient household balance sheets, and a reduction in effective US tariff rates are expected to support near-term growth.

2. Prolonged Disruption Scenario (Model-Based)

This scenario highlights the severe costs if a peace agreement is not secured until late in 2027.

• Market Shocks: Energy production remains subdued, and oil, gas, and fertiliser prices are assumed to rise by 50% relative to the time-limited scenario from Q3 2026 to Q3 2027.
• Global Recession Risks: Global growth would plummet to 2.1% in 2026 and 1.8% in 2027, potentially pushing several major economies into or close to recession.
• Higher Inflation: Global inflation would see significant upside pressure, rising by an additional 1.3 percentage points in 2027.
• Scarring Effects: The sustained period of lower energy supply and higher costs would lead to lower potential output starting in 2028 due to foregone investment and reduced efficiency.
• Financial Impact: This path involves a renewed tightening of financial conditions, a 15% decline in global equity prices, and an increase in risk premia.

Comparative Impacts and Specific Risks

The difference between these scenarios underscores the global economy's vulnerability to regional chokepoints.

• Regional Exposure: Many Asian economies face the heaviest impact in the prolonged scenario due to their high direct and indirect reliance on Persian Gulf energy.
• Industry Vulnerability: A prolonged conflict could specifically hinder the AI sector by increasing data center operating costs and disrupting the supply of critical hardware and specialized inputs like helium.
• Food Security: Persistent disruptions to fertiliser exports (like urea and ammonia) could lead to lower crop yields and substantial food price inflation well into 2027, particularly hurting developing nations.

Policy Implications

The Outlook emphasizes that "Under Pressure," policymakers must remain flexible and agile. Under the time-limited scenario, central banks can "look through" temporary price rises. However, in the prolonged scenario, many central banks would likely have to raise policy rates (by 50-75 basis points) to anchor inflation expectations, even as growth weakens. Fiscal policy would then face the primary burden of cushioning the downturn, despite already elevated public debt levels in many nations.

The global economy entered 2026 with more resilience than anticipated, driven by strong investment in artificial intelligence (AI), supportive financial conditions, and a temporary easing of trade tensions. However, the onset of the conflict in the Middle East has placed the global system "under pressure," primarily through severe disruptions to energy production and trade routes.

Growth and Inflation Projections

The OECD frames the outlook through two primary macroeconomic trajectories based on the duration of Middle East disruptions:

• Time-Limited Disruption: Under the assumption that energy production and shipping normalise by the third quarter of 2026, global GDP growth is projected to slow from 3.4% in 2025 to 2.8% in 2026, before a modest recovery to 3.1% in 2027. Inflation in G20 countries is expected to rise to 4.0% in 2026 due to the energy shock before easing to 3.1% in 2027.
• Prolonged Disruption: Should disruptions persist into late 2027, global growth could plummet to 2.1% in 2026 and 1.8% in 2027, potentially pushing several major economies into or near recession. In this scenario, global inflation would see significant upside pressure, rising by an additional 1.3 percentage points in 2027.

Key Drivers of Economic Pressure

Macroeconomic developments are currently dominated by several supply-side shocks and shifting fiscal priorities:

• Energy and Commodity Spikes: Global oil supply fell by 13.5% between February and April 2026, with Gulf production alone dropping by 45%. This has led to sharp increases in the prices of crude oil, natural gas, and fertilisers (like urea and ammonia).
• Trade and Logistics: Transits through the Strait of Hormuz remain severely restricted, leading to significant port congestion in the Red Sea and Oman. Global ocean freight rates have risen approximately 45% above pre-conflict levels.
• AI-Related Resilience: Despite these pressures, underlying momentum has been sustained by AI-related investment, particularly in the United States and advanced Asian economies. However, prolonged energy shortages could eventually raise data centre operating costs and disrupt the supply of critical hardware.
• Labour Markets: Employment conditions remain generally stable with low unemployment by historical standards, but real wages have been hit hard by the renewed spike in inflation, with one-third of OECD economies projected to have negative real wage growth in 2026.

Financial Conditions and Debt

Financial conditions have tightened since the onset of the conflict amid higher market volatility.

• Asset Pricing: Sovereign bond yields and corporate spreads have increased, reflecting expectations of higher inflation and risk premia.
• Corporate Debt: Total corporate debt in G20 economies remains high at roughly 90% of GDP. Significant refinancing needs are emerging just as borrowing costs rise, posing risks to firms with weaker balance sheets.
• NBFI Vulnerabilities: There are growing concerns regarding non-bank financial institutions (NBFIs), specifically private credit and equity funds, which have high exposure to the technology sector and face potential liquidity mismatches.

The Rising Impact of Defence Spending

A significant macroeconomic shift is the rapid, synchronised rise in defence spending across OECD nations.

• Fiscal Pressure: NATO members are moving toward a target of 3.5% of GDP for core defence spending by 2035.
• Economic Impact: While providing a modest near-term boost to activity in countries with domestic military production capacity, higher defence outlays add to public debt pressures and may crowd out private investment or other public spending (such as on climate or education) over the long term.

Policy Recommendations

The Outlook emphasizes that "flexible and agile" policies are required. Central banks must remain vigilant; while they may "look through" temporary supply-driven price rises, they must act if inflation expectations become de-anchored. Fiscal policy should provide targeted relief to vulnerable households but must also establish a credible path to long-term debt sustainability in the face of ageing populations and rising defence needs.

The financial landscape in mid-2026 is characterized by significant vulnerabilities that have been exacerbated by the conflict in the Middle East, placing global stability "under pressure." While financial conditions initially remained accommodative, the escalation of the conflict has triggered tighter conditions, higher market volatility, and a substantial repricing of assets.

Corporate Debt and Refinancing Strains

Total corporate debt in G20 economies remains historically high at approximately USD 90 trillion, or 90% of GDP. Firms now face a "maturity wall," with one-quarter of this debt set to mature within the next three years.

• Rising Costs: Much of this debt was issued during the low-rate period of 2018-21; firms must now refinance at significantly higher costs, with nearly half of outstanding investment-grade bonds carrying rates above 4%.
• Refinancing Risks: For financially weak issuers, prolonged energy disruptions and weaker growth could constrain access to credit, potentially lifting global speculative-grade default rates.

Vulnerabilities in Non-Bank Financial Institutions (NBFIs)

The rapid growth of the private capital market—now estimated at USD 22 trillion—has introduced new systemic risks.

• Private Credit and Equity: These funds have grown to USD 15 trillion in assets but face increasing concerns regarding liquidity mismatches and asset quality. Some large US private credit funds have already faced increased write-downs in 2026, leading to investor redemption requests and subsequent actions to limit those redemptions.
• Tech Exposure: Private equity and credit funds are heavily concentrated in the technology sector; software alone accounts for 42% of new US private equity investments in 2025.
• Interconnectedness: Banks have increasingly ceded lending activity to these alternative lenders and have simultaneously expanded their own lending to NBFIs. This creates a "leverage on leverage" effect that could amplify shocks through simultaneous deleveraging and fire sales.

Risks in the AI Sector

The rapid expansion of the artificial intelligence sector is creating specific financial fragilities.

• Valuation Risks: High valuations for AI stocks leave them vulnerable to correlated valuation shocks if expected returns fail to materialize.
• Opaque Financing: AI firms increasingly rely on less transparent private capital and "circular financing" arrangements, where AI firms act as both borrowers and creditors to one another.
• Energy Sensitivity: Because AI infrastructure (like data centers) is highly energy-intensive, the sector is uniquely sensitive to the energy price spikes caused by the Middle East conflict.

Sovereign Debt and Financing Shocks

Sovereign bond yields have risen across most markets due to higher inflation expectations and risk premia.

• Investor Base Shift: There has been a marked shift in who holds government debt, moving from central banks to more price-sensitive private investors, such as hedge funds. This transition increases the risk of financing shocks if investor sentiment shifts abruptly.
• Debt Sustainability: In many countries, current fiscal balances fall short of what is needed to stabilize debt ratios, especially as spending pressures rise for defence, ageing populations, and the green transition.

Scenario-Specific Financial Impacts

In the prolonged disruption scenario, where the conflict lasts well into 2027, the sources project a severe tightening of financial conditions:

• Equity Markets: A projected 15% decline in global equity prices.
• Risk Premia: Investment risk premia could rise by 75 basis points in advanced economies and 100 basis points in emerging markets.
• Default Risks: Sustained high energy costs and weak demand would likely lead to a sharp increase in corporate defaults and a significant scaling back of business investment.

To manage the global economy while it is "under pressure" from the Middle East conflict, the OECD recommends a suite of "flexible and agile" policies. These recommendations balance immediate crisis management with the need for long-term fiscal sustainability and structural resilience.

Monetary Policy: Vigilance and Anchoring Expectations

Central banks are advised to remain vigilant and attentive to shifting risks.

• "Looking Through" Shocks: Central banks can generally "look through" temporary supply-driven price rises if inflation expectations remain well-anchored.
• Rate Adjustments: Policy adjustments will be necessary if price pressures broaden (as in the prolonged disruption scenario) or if growth weakens significantly.
• Liquidity Support: If global financial conditions tighten severely, central banks should consider enhancing currency swap lines and reconsidering plans to reduce sovereign bond holdings.

Fiscal Policy: Targeted Relief and Sustainability

Fiscal space is constrained by elevated public debt and rising spending pressures from ageing, defence, and the green transition.

• Energy Relief: Support for households and firms should be well-targeted toward those most in need to contain fiscal costs and preserve incentives for energy conservation.
• Sunset Clauses: Measures should include automatic sunset mechanisms to ensure they are phased out once energy prices decline.
• Sustainability Path: Governments must establish a credible fiscal path to debt sustainability, requiring efforts to improve public sector efficiency and reallocate spending toward growth-enhancing investments.

Energy Security: Diversification and Efficiency

The vulnerability of global economies to a single chokepoint (the Strait of Hormuz) necessitates urgent shifts in energy policy.

• Diversification: Governments must intensify efforts to diversify energy supplies and reduce reliance on fossil fuel imports from single chokepoints.
• Efficiency and Electrification: Improving energy efficiency through regulatory standards and accelerating the electrification of end-uses are key to structural resilience.
• International Coordination: In the near term, international coordination of strategic energy stocks and emergency demand-restraint measures can help mitigate supply crunches.

Financial Stability: Addressing New Vulnerabilities

The OECD highlights the need for robust supervision to safeguard the financial system.

• NBFI Oversight: Progress is needed on regulatory policies for non-bank financial institutions (NBFIs) and crypto-assets.
• Enhanced Stress-Testing: Stress-tests should explore the potential effects of long-lasting Middle East disruptions and marked changes in AI valuations given the increasing interconnectedness between banks and NBFIs.

Structural Reforms and Trade

To improve medium-term growth prospects, the OECD suggests several reform priorities:

• Reducing Barriers: Actions to reduce regulatory burdens, simplify insolvency procedures, and promote product market competition.
• Labour and Skills: Policies to strengthen skill development, expand lifelong learning, and reduce tax wedges to promote labour mobility and participation.
• Trade Policy: Countries should avoid new export restrictions, which exacerbate global shortages, and instead engage in constructive dialogue to resolve trade tensions.

Defence Spending: Efficiency and Coordination

With defence spending rising toward a NATO target of 3.5% of GDP, the OECD emphasizes efficient resource management.

• Procurement Reform: Governments should improve procurement practices to reduce waste and harness competition.
• International Cooperation: Coordination in military purchases, particularly in Europe, could enlarge markets for productive firms and support interoperability.
