The evolving conflict in the Middle East is having significant humanitarian costs and testing the resilience of the global economy. The duration and extent of the conflict remain uncertain, though at the time of finalising the Outlook there are some encouraging signs of a negotiated settlement. Even after the conflict ends, the economic effects are likely to be felt for some time given the months it will take to restore damaged infrastructure and transport routes and deliver products around the world. Energy prices and the prices of other key agricultural and industrial inputs produced in the Persian Gulf economies have soared since February as production and exports have been curtailed, with the likelihood of shortages and actions to reduce energy usage becoming more pronounced in all countries the longer the conflict persists. Headline inflation has been pushed up in many economies, hitting the real incomes of households. Consumer and business confidence have eased and some signs of supply shortfalls have emerged. Many Asian economies are the most directly exposed to these shocks given their reliance on imports from the Middle East but the impact will be felt everywhere given interlinkages in global supply chains and integrated global energy markets. The heaviest burden is likely to fall on commodity-importing developing economies, as they are least able to attract scarce supplies or cushion households and firms against the shocks, and on the Gulf economies themselves.
Given the exceptionally uncertain situation and the extent to which economic prospects depend on achieving a durable resolution to the conflict, this Economic Outlook presents two different scenarios of how the global economy might evolve over the next eighteen months. These are largely shaped by the evolution of the energy crisis, the time taken to achieve a lasting settlement to the conflict and the resulting policy responses, and highlight the range of possible outcomes that might occur. Both scenarios occur against a background of an otherwise solid underlying momentum in the global economy, with output boosted by strong AI-related investment, production and trade, and supportive financial and fiscal conditions. Lower US effective tariff rates on imports than originally announced have also reduced headwinds to growth.
A projections-based scenario is one in which the disruptions from the conflict are sizeable but limited to a relatively short period of time, hereafter referred to as the “time-limited disruption” scenario. Energy prices are assumed to decline gradually over time in line with futures prices, amidst progress towards a negotiated and durable peace agreement. Energy production and trade in the Gulf economies gradually return to pre-conflict levels from the third quarter of 2026 onwards in this scenario. There may be some limited energy shortages in some economies, especially in Asia, but the use of strategic reserves, oil in transit or stored on tankers, and some modest additional supply from non-Gulf producers helps to cushion the shock. Global GDP growth is projected to slow from 3.4% in 2025 to 2.8% in 2026 before picking up to 3.1% in 2027. Policy interest rates are expected to remain broadly stable this year in most major economies with underlying price pressures generally projected to remain contained, before easing slightly in 2027. The fiscal stance is anticipated to be broadly neutral in the majority of countries in the near-term, with planned consolidation measures often being offset by additional expenditure to cushion the impact of energy price shocks on households and companies. Annual consumer price inflation in the G20 countries is expected to rise to 4.0% in 2026 from 3.4% in 2025, before easing to 3.1% in 2027 as energy price pressures fade and food price pressures peak. Core inflation is expected to return close to target in many economies by the end of 2027. If a lasting settlement is attained, with larger declines in energy prices than implied by futures prices in late May, then global growth is likely to be marginally higher and inflationary pressures lower. For instance, an additional decline of 10% in oil and gas prices and fertiliser costs from the latter half of 2026 would raise global GDP growth by an additional 0.1 percentage point in 2027 and reduce global inflation by 0.3 percentage points.
A model-based analysis, hereafter referred to as the “prolonged disruption” scenario, highlights the potential costs of failing to secure a peace agreement until well into 2027. The current disruptions to energy production and exports in the Gulf economies are assumed to persist until the latter half of 2027, before gradually fading thereafter. In this scenario, the likelihood of substantial shortages of energy products and agricultural and industrial inputs produced by the Gulf economies is high, resulting in scarring effects on potential output via lower efficiency and foregone investment. Global energy and fertiliser prices are significantly higher for an extended period relative to the time-limited disruption scenario, financial conditions are considerably tighter and household and business confidence substantially weaker. Global growth is expected to slow significantly, to just 2.1% in 2026 and 1.8% in 2027, pushing several economies into or close to recession, and raising unemployment. Global inflation is raised, by an additional 0.4 percentage points in 2026 and 1.3 percentage points in 2027, with upside pressures from elevated commodity prices partially offset by weaker final demand. Many Asian economies would be hard hit in this scenario, reflecting their heavy exposure to energy supplies from the Middle East. Policy interest rates would be likely to rise from current levels in 2026, by between 50‑75 basis points in most countries to help moderate inflation pressures, with these increases being removed gradually in 2027 as downward pressure on growth intensifies. Budgetary pressures are increased because of the weaker economy and higher interest costs on new debt issuance, potentially limiting the space available for discretionary measures to help stabilise activity.
There are many other factors that could affect the outlook under either scenario. Prolonged disruptions to the supply of energy and energy products could adversely affect AI investment due to the dependence of key infrastructure on energy availability and on products, such as semiconductors, that rely on specialised inputs from the Gulf economies. A further increase in national export restrictions for key products in short supply would add to policy uncertainty and intensify the impact of prolonged supply disruptions and energy shortages. There could also be more extensive risk repricing in financial markets than seen so far, adding significantly to the existing pressures on some highly leveraged non-bank financial institutions such as private credit and equity funds. Higher energy import costs could widen external deficits in commodity-importing emerging and developing economies, putting pressure on reserves and external financing conditions. On the upside, a continuation of the recent resilience and adaptability to shocks shown by the business sector, and increasing visibility of the possible productivity gains from AI technologies could push growth higher, especially in 2027. Further changes to US tariff levels could raise or lower trade, policy uncertainty and growth.
Given the high level of uncertainty, flexible and agile policies are needed to ensure macroeconomic stability. Polices also need to focus on medium-term challenges, including the need to establish a credible fiscal path to debt sustainability, enhance energy security, secure a lasting decline in trade tensions and strengthen the prospects for sustainable and resilient growth.
Central banks need to remain vigilant and attentive to shifts in the balance of risks around economic and financial developments to ensure that underlying inflation pressures are durably contained. The current supply-induced rise in global energy prices can be looked through provided inflation expectations remain well-anchored, but policy adjustment will be needed if there are signs of broader price pressures, as in the prolonged disruption scenario, or signs of a significant growth moderation. Clear communication is needed to ensure that the factors behind finely balanced policy decisions are well understood. In the event of a significant tightening of global financial conditions, it could be necessary to enhance currency swap lines and reconsider the current plans of some central banks for a further reduction in sovereign bond holdings.
Government measures to cushion the impact of higher energy prices should, be well‑targeted on households most in need and viable firms, while preserving incentives to reduce energy use and diversify energy sources. Such measures should also include clear sunset mechanisms as energy prices decline. Untargeted support and measures such as tax reductions and price caps are likely to have higher fiscal costs and weaken incentives to reduce energy use, delaying the necessary adjustment in energy demand. Such policies would be particularly costly should the impact of the conflict in the Middle East persist. If growth weakens substantially, as in the prolonged disruption scenario, fiscal policy will need to provide any necessary stimulus to cushion output given the limited scope for monetary policy to do so. The scope to act is likely to vary across countries according to their current budgetary position, with many emerging and developing countries particularly constrained. Careful policy choices will be needed to ensure that any stimulus measures do not magnify imbalances in energy markets or intensify inflationary pressures.
The potential need for further stimulus in the prolonged disruption scenario highlights that stronger efforts to contain and reallocate spending, improve public sector efficiency and enhance revenues are required to ensure longer-term debt sustainability and maintain the ability to react to significant shocks. The pace and composition of such adjustments will depend on the specific circumstances and challenges in each economy over time but should seek to preserve and foster the growth potential on which debt reduction ultimately depends.
Safeguarding financial stability requires robust supervision, progressing with robust regulatory policies for non-bank financial intermediaries (NBFIs) and crypto-assets in line with internationally agreed recommendations, and closing remaining data gaps on the many less regulated NBFIs. Enhanced stress-testing frameworks are also needed to better assess the risks around the increasing interconnectedness between banks and NBFIs, including scenarios that explore the potential effects of long-lasting disruptions in the Middle East and to marked changes in AI valuations.
The vulnerability of economies to future energy supply shocks can be mitigated by efforts that improve the diversification of energy supply and promote energy efficiency, highlighting the importance of maintaining clear price signals in energy support measures. In the near-term, emergency demand‑restraint measures and international coordination of strategic energy stocks can help mitigate adverse supply disruptions.
Constructive dialogue between countries is central to ensure a lasting resolution to trade tensions. Agreements to ease trade tensions and deepen trade relations would improve policy certainty, help ensure well-functioning and open global markets, and strengthen the prospects for investment, productivity and output growth. New export restrictions in response to supply disruptions should be avoided, as these only exacerbate global product shortages and push up prices.
Enhanced reform efforts can improve the foundations and prospects for sustainable medium‑term growth and improve resilience. Actions to reduce regulatory burdens, strengthen skill development, and promote labour mobility and participation are especially important. Collectively, these improve the investment incentives and the capacity for workers and markets to adjust smoothly to structural changes in the mix of tasks and jobs over time, including those that result from new digital technologies.
