The Organisation for Economic Co-operation and Development (OECD) has issued stark warnings about the serious repercussions of geopolitical tensions in the Middle East. In its latest report, released on Thursday, the organization explained that an escalation of the conflict and the outbreak of a full-blown confrontation would derail growth, clearly highlighting the close link between a war with Iran and the global economy . The OECD noted that a potential near-total disruption of energy shipments through the strategic Strait of Hormuz would send shockwaves through markets, threatening to sharply increase inflation and shatter hopes for economic recovery.
The historical roots of tensions and their impact on energy corridors
To understand the implications of these warnings, one must consider the broader context and historical background of the event. The Middle East, and specifically the Arabian Gulf and the Strait of Hormuz, has always been a vital artery for global oil and gas supplies. Historically, any conflict in this region, from the oil crisis of the 1970s to the Tanker War of the 1980s, has led to devastating global energy crises. Today, history is repeating itself with escalating mutual threats, as approximately one-fifth of the world's daily oil consumption passes through the Strait of Hormuz. This critical interdependence makes any threat to navigation in this waterway a direct threat to international economic security, explaining the deep concern expressed by major financial institutions regarding any potential military escalation.
The repercussions of the Iran-Iraq war on the global economy: local and international dimensions
The significance of this event and its anticipated impact are multifaceted, extending beyond the warring nations to encompass both emerging and developed markets. Regionally, the conflict will disrupt development plans and reduce foreign direct investment in the Middle East. Internationally, the repercussions of a war with Iran and on the global economy will be evident in rising production and transportation costs, straining the budgets of energy-importing countries. The OECD, headquartered in Paris, confirmed that the global economy was steadily progressing toward strong growth before these tensions escalated, bolstered by lower tariffs and technological investments. However, the specter of war threatens to completely erase these gains, presenting policymakers with unprecedented challenges in controlling prices.
Grim outlook for growth and inflation in major economies
In its detailed report, the OECD paints a pessimistic picture of the near future. Global GDP growth is expected to slow from 3.3% last year to 2.9% by 2026, before recovering slightly to 3% in 2027. This decline is primarily attributed to the anticipated surge in energy prices and the unpredictable nature of conflict.
For the United States, the OECD expects headline inflation to jump to 4.2% in 2026, an increase of 1.2 percentage points from previous forecasts, which will force the Federal Reserve to adopt tighter monetary policy. In China, the world's second-largest economy, growth is expected to slow to 4.4% in 2026 and 4.3% in 2027, in line with the OECD's previous estimates but within a more fragile global environment.
In Europe, the impact will be more severe, with the Eurozone's GDP growth expected to fall to just 0.8% in 2026. This setback is a direct result of the negative impact of rising energy prices on industrial and economic activity, before rebounding to 1.2% in 2027, mainly supported by increased defense and military spending in response to growing security threats.
