The escalating conflict between Israel and Iran has sent shockwaves through global supply chains, threatening energy markets, trade routes, and economic stability worldwide.
With attacks on critical infrastructure, threats to the Strait of Hormuz, and disruptions in oil and gas production, the war risks triggering a new era of inflation, recession, and supply chain paralysis.
Israel is already bearing massive economic costs. Estimates suggest that a month-long war could cost Israel around $12 billion, with daily military expenses averaging $725 million. If Iran targets more civilian infrastructure, these costs could escalate sharply. Over 5,000 Israelis have already been evacuated from their homes due to missile strikes. Labor shortages are worsening as tens of thousands of reservists, many from critical high-tech and industrial sectors, are mobilized. By the end of 2024, the Gaza war had already drained Israel of over $67.5 billion, excluding significant civilian and infrastructure damages and broader economic losses, which remain difficult to quantify.
Even before the Israel strikes, Iran faced a daunting infrastructure crisis, urgently needing over $500 billion in investments to address critical economic shortfalls exacerbated by U.S. sanctions. Israeli attacks have deepened this crisis, destroying vital civilian and energy infrastructure. The direct costs of reconstruction alone could reach tens of billions of dollars, adding enormous strain to Iran’s already battered economy and limited fiscal resources. Iran’s Kharg Island, responsible for 90% of its oil exports, has seen activity grind to a halt. Israel’s Leviathan and Karish gas fields have been shut down, cutting off two-thirds of its gas supply and impacting exports to Egypt and Jordan. The Strait of Hormuz, through which 20% of global oil and 25% of LNG flows, faces potential closure, which could send oil prices soaring to $150 per barrel. Brent crude has already surged from $72 to $78 per barrel, with analysts warning of a 1970s-style oil shock if the conflict worsens. Iran’s oil exports have plummeted from 1.7 million barrels per day to just 102,000, tightening global supply. Maritime insurance costs have risen by 30% due to Houthi attacks in the Red Sea and fears of Iranian mining in the Strait of Hormuz. JPMorgan Chase has restricted non-essential travel to the Middle East, reflecting corporate fears of prolonged instability.
Oil markets are entering a new phase of uncertainty after the U.S. joined the war between Iran and Israel, with experts warning of triple-digit prices. Investors are closely watching for Tehran’s reaction following the U.S. strikes on its nuclear facilities, with Iran’s foreign minister warning his country reserved “all options” to defend its sovereignty. Oil futures were up over 2% as of early Asia hours. U.S. WTI crude rose more than 2% to $75.22 per barrel, while global benchmark Brent was up nearly 2% at $78.53 per barrel. “There is real risk of the market experiencing unprecedented supply disruptions over coming weeks, of a much more severe nature than the oil price shock in 2022 in wake of the Ukraine war,” said MST Marquee’s senior energy analyst Saul Kavonic. Every $10 increase in oil prices could raise U.S. inflation by 0.5%, potentially pushing it to 5.5% if prices hit $130 per barrel. Gasoline prices in the U.S. may surge to $7 per gallon, adding $2,500 annually to household expenses. A prolonged conflict could slash 0.4% off global GDP growth and increase inflation by 1.5%, leading to stagflation.
President Trump has vowed further strikes if Iran refuses diplomacy, while Democrats demand congressional oversight under the War Powers Act. Moscow has condemned U.S. actions, while China may benefit from higher oil prices as Russia and Iran compete for its market. With U.S. arms potentially diverted to Israel, Kyiv fears losing critical anti-drone missiles, weakening its defense against Russian Shahed drones.
Oil prices stabilize, supply chains recover, and diplomacy resumes. Continued tensions keep oil prices volatile, inflation high, and shipping costs elevated. Strait of Hormuz blockade triggers $100+ oil, hyperinflation, and a global depression. Threats of blocking the Strait of Hormuz, after Iran’s parliament approved closing it as per state media, have added to market jitters. The strait, which connects the Persian Gulf to the Arabian Sea, is a critical artery for global oil trade, with about 20 million barrels of oil and oil products passing through it per day. That makes up almost one-fifth of global oil shipments. If Iran does close the Strait of Hormuz, Western forces will likely “directly enter the fray” and try to reopen it, Kavonic told CNBC, adding that oil prices could approach $100 per barrel and retest the highs seen in 2022 if the closure goes beyond more than a few weeks. “Even a degree of harassment of passage through the strait, short of a full closure, could still see a serious heightening of oil prices,” said the senior energy analyst.
The Israel-Iran war is no longer just a regional conflict; it is a global economic crisis in the making. With energy markets in turmoil, supply chains buckling, and inflation threatening to spiral, the world economy stands on the brink. The coming weeks will determine whether diplomacy can avert catastrophe or if the world must brace for a prolonged economic storm. Along with that, the conflict could have significant implications for the global economy, including higher oil prices and supply chain disruptions, which could lead to slower economic growth, particularly in countries heavily reliant on oil imports. Higher energy costs could lead to increased inflation, potentially delaying interest rate cuts by central banks. The conflict could lead to increased market volatility, with potential impacts on financial markets and investor confidence.
