Iran Conflict 2026: Global Impact of Rising Oil Prices

By WorldReport.Press Team | March 27, 2026

The ongoing U.S.-Israeli conflict with Iran, now in its fourth week, has triggered one of the largest energy supply shocks in recent history. Disruptions in the Strait of Hormuz — through which roughly 20% of global crude oil and a significant share of liquefied natural gas (LNG) normally flow — have caused Brent crude prices to surge dramatically, reaching highs above $110–$119 per barrel before partially easing to around $106–$110.

This energy shock is rippling across the world, driving up fuel costs, reigniting inflation fears, and pressuring stock markets. Energy-importing nations in Asia and Europe are feeling the pain most acutely, while even net energy exporters like Australia face mixed effects through higher inflation and market volatility.

Here’s a detailed country/region-wise breakdown of the impacts as of late March 2026.

Japan: High Vulnerability, Strong Reserves but Rising Costs

Japan relies on the Middle East for approximately 95% of its crude oil imports, with about 70% of that transiting the Strait of Hormuz. It also sources a notable portion of its LNG from the region.

Key Impacts:

• Energy Prices: Retail gasoline prices have already started climbing sharply. The government has activated subsidies (potentially costing hundreds of billions of yen monthly) to cap prices and is drawing down both private and state oil reserves.
• Stock Market: The Nikkei 225 has fallen by around 8–11% since the conflict escalated in late February, reflecting broader investor concerns over energy costs and global growth.
• Economic Outlook: Higher import bills threaten to squeeze household spending and corporate margins. Japan’s large strategic petroleum reserves (covering hundreds of days of consumption) provide a buffer, but prolonged disruptions could push inflation higher and delay economic recovery. Some sectors, like petrochemicals and refining, face immediate cost pressures, with ripple effects on everyday goods (e.g., packaging and snacks).

Japan is actively monitoring the situation and has coordinated with allies on potential measures to secure shipping lanes.

Europe: Renewed Energy Crisis and Inflation Risks

European countries, still recovering from the energy fallout of the Russia-Ukraine war, now face a fresh shock to oil and especially LNG supplies from Qatar and other Gulf producers. European gas prices have jumped significantly (Dutch TTF benchmark up sharply, with some reports of 24–70% spikes in sessions).

Key Impacts:

• Energy Costs: Higher oil and gas prices are feeding directly into electricity, heating, and transportation. Jet fuel and diesel prices have risen markedly, affecting airlines, logistics, and manufacturing.
• Stock Markets: Europe’s STOXX 600 has declined around 6%, with major indices like Germany’s DAX, France’s CAC 40, and the UK’s FTSE 100 posting losses of 2–3% in volatile sessions. Energy-intensive industries (chemicals, steel, autos) are under pressure.
• Broader Economy: The European Central Bank and national governments are watching inflation closely. Economists warn that sustained high energy prices could reduce eurozone GDP growth by 0.5–1 percentage point or more. Countries like Germany, with heavy industrial bases, are particularly exposed. Some nations are considering price caps or support schemes, but fiscal space is limited after previous crises.
• Longer-Term Concerns: Replenishing gas storage for next winter will be more expensive and competitive, especially as Asian buyers vie for limited supplies.

Overall, Europe risks a return to stagflation-like conditions if the conflict drags on.

India: Severe Exposure to Import Costs and Growth Slowdown

India imports nearly 85–90% of its oil and a large share of its natural gas, with a significant portion historically linked to the Gulf region. It is one of the most vulnerable major economies to this shock.

Key Impacts:

• Fuel and Inflation: Higher global oil prices directly increase the cost of petrol, diesel, and cooking gas (LPG). This feeds into higher transportation and food costs, pushing overall inflation higher (projections suggest it could reach 4.1% or more if prices stay elevated).
• Current Account and Rupee: The import bill is ballooning, widening the current account deficit (potentially to 1.9–2.2% of GDP). The Indian rupee has seen sharp declines, hitting multi-year lows in some sessions.
• Stock Market: The Nifty 50 has dropped around 7% since late February, reflecting concerns over corporate margins and consumer spending.
• Growth Outlook: Economists warn that if Brent averages near $100 per barrel for an extended period, India’s GDP growth could slow to 6–6.6% (from earlier higher forecasts). The government is exploring measures like increased Russian oil purchases (with waivers) and boosting domestic refinery output, but subsidies to shield consumers will strain fiscal balances.
• Other Effects: Fertilizer production (heavily dependent on gas) and agriculture could face disruptions, adding to food price pressures.

India is actively diversifying supplies and managing strategic reserves, but the scale of the shock makes it one of the hardest-hit large economies.

Australia: Mixed Effects – Beneficiary in LNG but Inflation Headwinds

Unlike its Asian neighbors, Australia is a major net exporter of LNG and has significant energy resources, which provides some insulation and even upside.

Key Impacts:

• Energy Sector Gains: Higher global LNG and coal prices benefit Australian exporters. The mining and energy sectors have seen some support, though overall market sentiment remains cautious.
• Stock Market: The ASX 200 has declined 6% or more since the conflict began, driven by global risk-off sentiment and concerns over slower growth in key trading partners like China and Japan.
• Inflation and Policy: Rising imported fuel costs (Australia still imports refined products and some crude) add to domestic inflation pressures. The Reserve Bank of Australia has responded with interest rate hikes, signaling concerns that the oil shock could keep inflation “higher for longer.” Trimmed-mean inflation is under watch.
• Broader Economy: Higher energy costs could dampen consumer spending and slow growth slightly. However, Australia’s commodity exports (iron ore, LNG) may partially offset the pain if demand from Asia holds up. The Australian dollar has shown relative resilience in some trading.

Australia is positioned better than pure importers but is not immune, especially through trade linkages with hard-hit Asian economies.

Common Themes Across These Economies

• Inflation vs Growth Trade-off: Central banks face a dilemma — higher energy prices stoke inflation while simultaneously weakening demand and growth, raising risks of stagflation.
• Stock Market Volatility: Major indices in all these regions have posted losses ranging from 6–11%, with heightened daily swings tied to conflict headlines.
• Currency Pressures: Import-dependent currencies (yen, rupee, euro) have weakened against the dollar.
• Mitigation Efforts: Governments are releasing reserves (Japan, South Korea coordination), offering subsidies, seeking alternative supplies (e.g., more Russian oil for India), and coordinating internationally on shipping security.

Outlook: If the Strait of Hormuz disruptions ease quickly and tanker traffic resumes, prices could moderate and markets stabilize. However, a prolonged conflict or further infrastructure damage risks deeper and longer-lasting economic pain, particularly for Asia and Europe. The WTO and OECD have already flagged potential downward revisions to global growth.
