But the ongoing war involving Iran and the resulting blockade of the Strait of Hormuz are violently scrambling investment patterns within that fossil fuel sector, pushing some in the opposite direction of the clean transition.

The Strait of Hormuz: The Largest Energy Security Crisis in History

The numbers behind the Strait of Hormuz crisis are staggering. Since the United States and Israel launched military strikes on Iran on February 28, 2026, shipping through the narrow waterway—which normally carries about 20% of the world's seaborne oil trade—has been largely blocked .

The disruption has removed an estimated 11 to 14.5 million barrels per day (mb/d) of oil from the global market . This single event has a larger impact than the combined supply losses of the 1973 Arab oil embargo and the 1979 Iranian Revolution, a point IEA Executive Director Fatih Birol has made repeatedly since March . Birol has not minced words, calling the situation "the largest energy security crisis the world has ever faced" and "the biggest energy security threat in history" . Japan's central bank governor has framed it as a "fifth oil price shock" .

The Fossil Fuel Split: Oil Down, Coal and Gas Up

This historic crisis is creating a deeply contradictory set of incentives for fossil fuel investors.

Oil investment is falling for the third straight year. Despite elevated crude prices—Brent crude surged above $100 per barrel in early March and peaked at $126—the IEA projects that global upstream oil spending will decline again in 2026, dropping below $500 billion . The agency attributes this counterintuitive trend to deep uncertainty about how long high prices will last, long project development timelines, supply-chain constraints, and a structural shift of capital toward electrification . Simply put, investors are not convinced that this wartime price spike signals a lasting boom in oil demand worth betting a multi-year, multi-billion-dollar project on.

Natural gas investment is surging. The crisis is a powerful accelerant for the gas industry. With Qatari LNG shipments trapped behind the blockade and European and Asian nations suddenly desperate to replace lost energy flows, investment in liquefied natural gas (LNG) terminals, pipelines, and new supply infrastructure is expected to rise by more than 10% to around $330 billion—its highest level in a decade . Nations are scrambling to diversify trade routes away from the volatile Strait, fast-tracking alternative supply projects .

Coal is making a punishing comeback. The most troubling immediate trend is in coal. As the blockade drives oil and gas prices to painful levels, a number of countries are turning back to coal as a cheaper, often domestically-sourced alternative for power generation. The IEA reports that global coal investment is rising to approximately $180 billion, its highest level since 2012, wiping out years of progress toward a managed phase-down of the dirtiest fossil fuel .

The Clean Energy Counter-Current

Even as the short-term crisis revives coal and boosts gas, the overarching investment trend remains overwhelmingly tilted toward clean energy technologies. The $2.2 trillion flowing into clean electricity infrastructure is being propelled by a different, deeper driver than immediate fuel prices: the strategic imperative for energy independence .

For many nations, every barrel of displaced oil is being replaced not just with another fossil fuel, but with a structural investment in domestic renewables, nuclear power, and grid resilience that permanently reduces exposure to a volatile, choke-point-dependent global fuel market . The IEA's report makes clear that energy security concerns have become one of the single most powerful drivers of the clean energy build-out .

The Economic Fallout: Bangladesh and the New Wave of IMF Bailouts

The financial shockwaves from the energy crisis are not limited to investment boardrooms. They are crashing into the balance sheets of developing nations. Bangladesh has emerged as a high-profile example. On May 26–27, 2026, Bangladesh formally requested a new IMF-supported assistance program as the soaring cost of energy imports strains its economy to a breaking point .

IMF mission chief Ivo Krznar confirmed that negotiations are underway on a reform agenda and new policy priorities . Dhaka is seeking at least $2 billion in additional external financing on top of its existing IMF arrangements, with its central bank working to shore up strained foreign exchange reserves .

Bangladesh is not alone. While no single source has pinned a precise figure on the total aggregate need, the cascade of similar pressures across dozens of energy-importing developing economies suggests billions of dollars in additional financial support will be required globally to prevent wider economic instability.

A World Rewired by Crisis

The 2026 IEA report captures a world at an inflection point. The Strait of Hormuz crisis is simultaneously accelerating two opposite trends: a desperate, short-term dash to lock in any available fossil fuel supply (especially coal and gas), and a more strategic, long-term rush to build an electricity system that is insulated from such shocks forever.

The net flow of capital, dollar for dollar, remains locked at roughly a 2:1 ratio in favor of clean energy. But the surge in coal spending is a stark reminder that crises do not just accelerate the future—they can also resurrect the past.
