How the Iran War Is Shaking the Global Economy Through Energy Markets and the Strait of Hormuz

When conflict threatens this route, several economic effects ripple across global markets:

• Oil and gas supply risks push crude prices higher
• Shipping, freight, and insurance costs increase
• Energy‑intensive industries face higher input costs
• Global supply chains become less reliable

International institutions note that these dynamics behave like a textbook negative supply shock—raising production costs across economies while eroding consumer purchasing power.

Energy Prices and the Global Inflation Risk

Energy markets have been particularly sensitive to the conflict. Oil price spikes linked to the war have pushed energy costs higher worldwide, feeding into broader inflation pressures. In the euro area, for example, energy prices surged sharply and helped push annual inflation to around 3%, driven partly by a 10.9% increase in energy costs.

Global institutions warn that the broader commodity impact could be significant. The World Bank has projected that energy prices could rise by about 24% in 2026 due to the Middle East conflict, with overall commodity prices increasing as well.

Because energy is a foundational input for transportation, manufacturing, agriculture, and electricity, sustained increases can spread throughout the entire economy.

India: RBI Warns of Imported Inflation and Slower Growth

India’s central bank has been explicit about the risks. The Reserve Bank of India (RBI) has warned that the West Asia conflict could affect the country through several channels, particularly higher oil prices and disruptions around the Strait of Hormuz.

According to RBI officials and Monetary Policy Committee minutes, the conflict could:

• Raise imported inflation through higher crude prices
• Increase freight and insurance costs for trade
• Disrupt supply chains and the availability of key inputs
• Weaken economic growth if the shock persists

RBI Governor Sanjay Malhotra has said the central bank is closely watching whether the supply shock spreads more broadly through the economy and leads to generalized price increases. If inflation pressures become entrenched rather than temporary, policy action could be required.

At the same time, the RBI has noted that India’s macroeconomic fundamentals are stronger than in past energy shocks, potentially helping the economy absorb some of the impact.

Europe: Lower Growth and Higher Inflation Forecasts

Europe faces similar pressures because it is a large net importer of energy. The European Commission has warned that the conflict‑driven energy shock is weakening the region’s economic outlook.

In its latest forecasts, the Commission:

• Cut expected EU growth in 2026 to about 1.1%, down from earlier projections of 1.4%
• Lowered the eurozone growth forecast to roughly 0.9%
• Predicted higher inflation due to elevated energy prices linked to the conflict and shipping risks around the Strait of Hormuz

The concern is not only about energy prices themselves but also the broader effects on business confidence, investment, and household spending.

Why Policymakers Fear a “Stagflationary” Scenario

The combination of slower growth and rising prices is the outcome policymakers worry about most. Economists describe the Iran‑related energy disruption as producing the same macroeconomic dynamics seen during past energy crises: cost‑push inflation alongside weakening activity.

For central banks, this creates a difficult policy dilemma:

• Raising interest rates can control inflation but weaken growth further.
• Cutting rates to support growth risks fueling higher inflation.

As a result, many central banks are taking a cautious “wait‑and‑watch” approach while monitoring whether energy‑driven price increases spread across the broader economy.

The Global Outlook: Growth Slower, Inflation Higher

Across major economies, the transmission channel from the conflict is broadly the same:

Iran conflict → energy supply disruption → higher oil prices → rising transport and production costs → inflation pressure → weaker economic growth.

Even if the conflict remains geographically limited, sustained disruption to oil flows through the Strait of Hormuz could keep energy prices elevated and prolong inflation pressures worldwide. Economists therefore increasingly view the crisis as a key downside risk to the global economy in the near term.
