June 2026 has become a critical watershed moment for the global economy. Inflation is climbing sharply, propelled by the military conflict centered on Iran and the paralyzing closure of the Strait of Hormuz. This geopolitical crisis, initiated by the United States and Israel on February 28, 2026, has triggered severe disruptions across international energy markets, fractured fragile supply chains, and forced policymakers to confront a highly volatile economic landscape.
What began as "Operation Epic Fury" has expanded into a global crisis, exposing the vulnerabilities of modern interconnected trade. As the Strait of Hormuz remains largely impassable for maritime traffic [3], a vital transit corridor for much of the world's energy and resource flows is blocked, generating inflationary pressures and dragging down growth forecasts worldwide.

The current escalation began on February 28, 2026, when the United States and Israel launched attacks against targets in Iran. These initial strikes, which reportedly targeted the heart of the Iranian regime, Supreme Leader Ali Khamenei [4], triggered a swift and significant retaliation from Iran, involving hundreds of missiles and thousands of drones launched across the Middle East. This initial exchange reshaped regional security overnight, transforming a localized crisis into a broad conflict.
Since then, the war has featured intense maritime engagements and regional strikes. As recently as June 7, 2026, US forces have been actively shooting down Iranian drones threatening international maritime traffic in the Strait of Hormuz [6]. This defensive action highlights how contested these waters remain. Iran has also launched ballistic missiles targeting Kuwait and Bahrain, though many were intercepted [7]. Despite a fragile ceasefire agreed upon on April 8, hostilities have continued, and negotiations to end the war and reopen the Strait have repeatedly stalled [6]. Diplomatic efforts remain complex; while President Donald Trump has suggested the war is "largely finished," but indirect negotiations remain deadlocked as both sides hold to their core positions.
The Strait of Hormuz is the world's most critical maritime energy chokepoint. Through this strategic passage, over 20% of global crude oil and approximately 20% of global liquefied natural gas (LNG) supply transit to markets. Its effective closure since February 28, 2026 [3], or March 4, 2026, represents an unparalleled disruption to world energy supply since the 1970s energy crisis. This disruption has triggered systemic shocks across every level of global commerce.
+-------------------------------------------------------------+
| CONSEQUENCES OF THE CLOSURE |
+-------------------------------------------------------------+
| 1. Oil & LNG shortages (11-14M b/d out of global supply) |
| 2. Stranded Gulf exports (Kuwait, Iraq, Saudi Arabia, UAE) |
| 3. High freight rates & surging marine insurance premiums |
| 4. Minimal bypass capacity (<20% offset capability) |
+-------------------------------------------------------------+
- Massive Supply Shortfall: Massive Supply Shortfall: Approximately 11-14 million barrels per day (b/d) of Gulf crude and condensate supply have been curtailed [11]. A full closure would remove roughly 20 million b/d from global markets, accounting for about 20% of world petroleum liquids consumption. This has forced European and Asian refineries to seek costlier alternatives.
- Stranded Exports: Stranded Exports: Oil and LNG exports from major producers like Kuwait, Iraq, Saudi Arabia, and the United Arab Emirates have been severely impacted, with some experiencing significant drops in production and even force majeure declarations on exports [11]. Storage infrastructure in the Gulf is near capacity as tankers remain anchored, unable to safely transit out of the region.
- Limited Bypass Capacity: Limited Bypass Capacity: While some bypass pipeline capacity exists, it can offset less than 20% of the disrupted flows, leaving a substantial global deficit. Gulf countries are actively exploring and utilizing new trade corridors, such as the Oman-UAE route and the Neom logistics hub in Saudi Arabia, but these efforts cannot fully compensate for the Strait's closure. Overcoming these geographic bottlenecks requires long-term infrastructure investment that cannot be built overnight.
The combined impact of the Iran War and the closed chokepoint has intensified global inflation. This is primarily driven by three key factors:
The restriction on oil and gas deliveries has sent energy costs higher worldwide. Brent crude oil prices have risen nearly 31% since the war began, surging past $100 per barrel on March 8, 2026, and reaching a peak of $126 per barrel. Analysts warn that if supply disruptions persist, Brent could hit $150 per barrel and even approach $200 per barrel in an "Extended Disruption" scenario where the Strait remains largely closed through year-end.
These high energy costs affect refining and transportation sectors:
The energy crisis has a direct impact on global food supply networks. Modern agriculture relies heavily on energy inputs for farming, harvesting, processing, and transportation. The Middle East controls a significant portion of critical fertilizer components, and disruptions in the Strait of Hormuz have led to price surges of 30-40% for fertilizer markets by March, with nitrogen costs doubling compared to 2024 levels. This has caused a sharp rise in farm operating expenses worldwide.
This directly fuels food inflation, disproportionately affecting low-income countries where food constitutes a large share of household expenditure [7]. Elevated agricultural inputs have forced farmers in regions like Sub-Saharan Africa and South Asia to reduce fertilizer usage, threatening future crop yields. The UN's World Food Programme (WFP) warns that if oil prices remain above $100 per barrel, an estimated 45 million more people worldwide could face acute hunger, showing the human cost of this geopolitical conflict.
The economic fallout extends beyond energy and food markets. Key industrial materials have also seen supply lines disrupted:
- Chemicals and Materials: Chemicals and Materials: The Middle East accounts for nearly half of the global sulfur market, a vital industrial input, and a significant portion of helium, critical for semiconductor manufacturing [13]. Sulfur shortages have hit battery production and paper manufacturing, while helium supply concerns put high-tech industries at risk.
- Semiconductors: Semiconductors: Countries like Taiwan and South Korea, reliant on Middle Eastern helium, face potential 10-20% production dips, delaying the global semiconductor recovery and potentially adding $50-100 billion to global production costs between 2027 and 2030. This has raised concerns of a renewed electronics shortage, impacting automotive and defense industries.
- Manufacturing Costs: Manufacturing Costs: Supply bottlenecks in the tech sector, coupled with rising import and transportation costs, are putting upward pressure on core goods prices [17]. Companies are passing these accumulated transport and component costs on to consumers, keeping core inflation high.
The dual shock of inflation and trade disruptions has altered the economic landscape for 2026, leading to lowered growth projections.

Central banks face challenging choices. Many had anticipated stable inflation at the start of the year, hoping to lower rates. However, the energy price spike and strong growth momentum are now "stoking inflation, paving the way for monetary policy tightening". This shift is complicating previous plans for policy normalization.
To counter these pressures, central banks are adjusting rates. The European Central Bank and the Bank of Japan are expected to raise policy rates in June to anchor inflation expectations. Concurrently, The San Francisco Federal Reserve noted that "households and financial market participants now expect inflationary pressures to persist somewhat", showing that inflation concerns have become embedded in consumer expectations.
This economic impact is distributed unevenly across global regions. Energy importers are far more exposed, and poorer countries face greater strain from higher food and fertilizer prices and tighter financial conditions [14]. This has worsened balance-of-payments challenges in vulnerable emerging markets. The UN Development Programme estimated that the war could reduce economic growth in Arab nations by $120–194 billion in GDP. Some neighboring economies face severe economic and fiscal challenges. Iraq, heavily dependent on oil and gas for 90% of its income and 90% of its imported goods via the Strait of Hormuz, is particularly hard hit, illustrating the high vulnerability of producers reliant on a single trade corridor.
The road ahead remains uncertain. While some efforts are underway to mitigate the impact, such as OPEC+ preparing its fourth increase in oil production quotas to stabilize the market, these supply increases cannot solve the physical transit constraints through the Persian Gulf.
These disruptions are accelerating a strategic shift toward supply chain resilience over cost efficiency. The shift towards supply chain resilience over efficiency, accelerated by this crisis, is expected to lead to a higher cost of living and potentially a slower pace of technological growth in the long run. This near-shoring and friend-shoring trend introduces structural costs that are likely to persist. In response, Businesses and governments are being forced to adapt, reconfiguring supply chains and exploring alternative routes [15]. This transition involves significant initial capital expenditure.
As June 2026 progresses, markets continue to closely monitor the Middle East. Reopening the Strait of Hormuz is essential for easing global inflationary pressures and supporting a more stable growth outlook. Until a diplomatic or operational resolution is achieved, global commerce must adapt to higher baseline costs, continued volatility, and a landscape reshaped by geopolitical risk.
