Global Economic Outlook Highlights Risks from US-Iran Conflict and AI Investment Trends

According to Wood Mackenzie’s Q3 2026 Global Economic Outlook, while the world economy shows resilience amid significant pressures, a downside scenario could drastically alter investment strategies. The baseline forecast has been revised upward, with projected global GDP growth of 2.5% for 2026, up from 2.3%, and an expectation of recovery to 3.0% in 2027. This growth is supported by three main factors: drawdowns of strategic energy reserves by major economies, the rerouting of energy exports from the Gulf, and a surge in AI investments, particularly in the US and Asia.

However, this stability hinges on a crucial assumption: that normal energy traffic through the Strait of Hormuz resumes promptly. If disruptions continue, the potential for a global recession looms, characterized by depleting reserves, rationing, rising prices, inflation, tighter monetary policy, and contractions in developed markets. The recent collapse of the US-Iran Memorandum of Understanding in June has already pushed back recovery timelines.

Investors should be aware of the divergent regional forecasts:

- **Middle East**: Countries including Iraq, Kuwait, Iran, and Qatar are expected to contract in 2026. Saudi Arabia, which experienced a 4.8% GDP contraction year-on-year in Q2, benefits from its diversification efforts, with non-oil revenues constituting 46% of government income, up from 27% in 2015. A rebound of 7.5% GDP growth is forecasted for 2027 as oil production rebounds.

- **Asia**: Taiwan, South Korea, and Malaysia are positioned as key beneficiaries of the AI supply chain, with exports increasing over 40% year-on-year in the first half of the year. Taiwan’s Q1 GDP growth of 14.5% showcases the significant opportunity within AI-related manufacturing.

- **United States**: The AI investment wave is estimated to have contributed 61% to US GDP growth in H1 2026, making it the primary growth driver. Investment by top tech firms is projected to exceed $700 billion in 2026, providing a strong structural boost despite restrictive monetary policies keeping rates at 3.75%.

- **Europe**: The region is lagging behind, with EU-27 GDP growth forecast at only 1.1% in 2026. Europe struggles to leverage the high-margin value of AI intellectual property, hindered by regulatory issues and lack of domestic hyperscalers.

The current environment of geopolitical fragmentation is reshaping the global economy. The US-China AI race, alongside supply chain and energy security challenges, indicates that elevated geopolitical risks will persist. This fragmentation may redefine global trade patterns, commodity demands, and investment landscapes for the foreseeable future.

Long-term projections anticipate an increase in global real GDP from $99 trillion in 2025 to $213 trillion by 2060, though demographic trends and geopolitical tensions introduce notable risks to this forecast.
