The Looming Oil Shock: US-Iran Conflict and Global Economic Implications

When war breaks out in the Middle East, its impact doesn’t stop at the battlefields; shockwaves are felt across the world, especially in oil markets, financial systems, and national economies. The renewed conflict between the United States and Iran has once again reminded the world of the vulnerability of the world’s oil supplies. Oil prices are soaring in the wake of rising tensions, and economists are drawing parallels to crises that reshaped the world’s economic order.

The Strategic Importance of Middle Eastern Oil

Though oil is at the core of geopolitics, nowhere is its importance felt more than in the Middle East, where nearly half of the world’s proven oil reserves are located, and the region is the focal point of global petroleum exports. Instability in the Middle East means instability in oil supplies, which will have a ripple effect on national and international economies, from the industrial nations of Europe and East Asia to oil-dependent developing nations.

The US and Israel launched strikes on Iran on February 28, 2026, targeting Iranian military assets and leadership, resulting in the death of Supreme Leader Ayatollah Ali Khamenei [1]. Mojtaba Khamenei, his son, was subsequently appointed as his successor by the Assembly of Experts [1]. Iran has retaliated by targeting U.S. Military facilities, as well as energy and civilian infrastructure in the Gulf states [1].

Iran is a geopolitically critical country located on the northern coast of the Persian Gulf and is a neighbor to the Strait of Hormuz, a key shipping channel for oil tankers. Approximately 20 million barrels of oil pass through the Strait each day, equating to one-fifth of the world’s oil consumption and a third of all oil traded by sea.

Any interruption in oil flow through the Strait of Hormuz will result in immediate shortages in major oil-importing countries such as China, India, Japan, and South Korea, sending oil prices skyrocketing. Iran has repeatedly threatened to close the Strait if its security is threatened, a threat that has already unsettled oil traders and investors.

Historical Precedents: Oil Shocks of the 1970s

The instability of the region’s oil infrastructure has been experienced before. In 2019, drone and missile attacks on Saudi Arabia’s Abqaiq oil processing facilities took out nearly five percent of the world’s oil supply overnight, causing oil prices to rise sharply.

To appreciate the potential impact of the current crisis, it’s crucial to examine the 1973 Oil Crisis. The crisis began during the Yom Kippur War when Egypt and Syria attacked Israel in October 1973. In retaliation for Western support of Israel, Arab countries in the Organization of Petroleum Exporting Countries (OPEC) imposed an oil embargo against the US and several European countries.

The industrial world was highly dependent on Middle Eastern oil at the time and lacked strategic reserves. Within a year, the price of oil quadrupled from about $3 to nearly $12 per barrel. The economic impact was severe, with fuel shortages, long lines at gas stations, fuel rationing, and a slowdown in economic growth. The crisis also created stagflation, a combination of high inflation and low growth.

Just six years later, the Iranian Revolution of 1979 caused another surge in oil prices. The revolution disrupted the Iranian oil industry, leading to a decline in exports. Even though the actual cut in oil supply wasn’t large, the psychological impact was significant, as energy traders feared unrest could spread to other parts of the Persian Gulf. Oil prices almost doubled, increasing from $15 to $39 per barrel, resulting in another economic shock and global slowdown.

How Today’s Crisis Differs

While oil supply crunches have occurred before, the world today is different than it was during the 1970s. Over the last five decades, governments and industries have taken steps to reduce their dependence on oil. These include the establishment of strategic petroleum reserves, diversification of energy resources (gas, nuclear, wind, and solar), and technological innovation, such as the shale revolution in the US, which has increased global energy supply.

However, the modern global economy is still heavily reliant on oil for aviation, shipping, transportation, and many industrial processes. Any sharp increase in oil prices can still cause a ripple effect throughout the economy.

The Inflation Threat and Impact on Developing Economies

One immediate effect of rising oil prices is inflation. Increased fuel prices raise transportation costs, production expenses, and the cost of producing agricultural products. Businesses typically pass these higher costs onto consumers. Rising oil prices could lead to stagflation, characterized by high inflation and stagnating economic growth, especially as the global economy is still recovering from the COVID-19 pandemic.

For developing economies like Bangladesh, which heavily depend on imported oil, rising prices can be devastating, leading to increasing trade deficits, a depreciating local currency, and difficulties in maintaining fiscal balance. These nations may be prompted to invest more in alternative energy sources.

Recent Oil Price Surges

Over the past several decades, geopolitical crises have repeatedly driven oil prices higher. The 1973 oil embargo, the Iranian Revolution of 1979, the Gulf War of 1990, and rapid global economic growth in 2008 all led to significant price increases. More recently, Russia’s invasion of Ukraine and the escalation of the Middle East conflict have pushed oil prices over $100 a barrel.

A Critical Moment for the Global Economy

The world is at a critical juncture where geopolitics and oil prices are interlinked, potentially altering the global economic order. If tensions between the US and Iran remain contained, oil prices are likely to remain stable. However, if tensions escalate, especially if the Strait of Hormuz is closed, the consequences for the world economy could be immense.

History shows that oil price shocks often mark a turning point in the global economy. The current scenario has not yet reached those levels, but the warning signs are ominous. Oil price hikes, geopolitical tensions, and economic instability are a potent mix that economic policymakers cannot ignore. In a globalized world, energy security is a key component of economic stability.
