US–Israel Iran War Explained: Timeline, Oil Price Impact and the Risk of World War 3
The conflict involving the United States, Israel and Iran has become one of the most serious geopolitical crises of the decade. What began as military strikes has quickly evolved into a broader confrontation affecting global politics, energy markets and international security.
Many people around the world are now asking three key questions. What exactly has happened so far in the war? How could the conflict affect global oil prices and the economy? And perhaps the most worrying question: could this war escalate into a third world war?
To understand the situation clearly, it is important to examine the timeline of events, the strategic importance of the Middle East for global energy supply and the geopolitical dynamics shaping the conflict.
Timeline of the US–Israel Iran War: What Happened So Far
The current war began in late February 2026 after a major escalation between Israel, the United States and Iran.
On February 28, 2026, the United States and Israel launched coordinated airstrikes targeting Iranian military infrastructure and nuclear-related facilities. The attacks were part of a joint military operation aimed at weakening Iran’s strategic capabilities.
The strikes targeted several important locations, including military bases and command centers across Iran. According to reports, the operation also resulted in the death of Iran’s Supreme Leader Ayatollah Ali Khamenei, a development that dramatically intensified the conflict.
Iran responded quickly with missile and drone attacks targeting Israeli cities and U.S. military bases in the Gulf region. Several countries hosting American forces, including Bahrain, Qatar and the United Arab Emirates, reported incoming projectiles during the early phase of the war.
Within days, the conflict expanded beyond Iran and Israel. Iran-backed Hezbollah launched rockets from Lebanon into Israeli territory, prompting retaliatory strikes by Israeli forces. The fighting quickly spread across multiple fronts in the Middle East.
Another major development occurred in early March when Iran warned ships against passing through the Strait of Hormuz, one of the most important shipping routes in the world.
Why the Strait of Hormuz Is So Important
The Strait of Hormuz is a narrow waterway between Iran and Oman that serves as a gateway for global oil exports.
Every day, around 20 million barrels of oil—roughly 20 percent of the world’s supply—pass through this route.
When the conflict escalated, tanker traffic in the strait dropped dramatically as shipping companies feared attacks and insurance costs surged. At one point, more than 150 oil tankers were forced to anchor outside the strait, unable to continue their journeys safely.
The disruption immediately triggered fears of a global energy crisis.
How the Iran War Is Affecting Oil Prices Worldwide
Oil prices respond quickly to geopolitical tensions, especially when conflicts occur in the Middle East.
Since the beginning of the war, crude oil prices have surged sharply as traders worried about supply disruptions. Gasoline prices in the United States jumped around 14 percent within a single week, reflecting the sudden shock to global energy markets.
The rise in prices is mainly driven by concerns about oil shipments through the Strait of Hormuz. If the strait remains blocked or restricted for a long period, global oil supply could shrink dramatically.
Energy analysts warn that prolonged disruption could push crude oil prices toward $100 per barrel or higher.
Some oil-producing countries have already begun adjusting production levels because shipments cannot leave the region easily. Kuwait, for example, recently cut crude oil output due to the conflict and disruptions in shipping routes.
The Global Economic Ripple Effect
Oil is one of the most important commodities in the global economy. When prices rise sharply, the effects spread across many industries.
Higher oil prices increase transportation costs, which then raise the prices of goods such as food, electronics and clothing. Inflation often rises as businesses pass on higher fuel costs to consumers.
Economists warn that prolonged energy disruptions could weaken global economic growth. Rising energy costs may force central banks to rethink interest rate policies while governments struggle to manage inflation.
Even countries far from the conflict can feel the impact.
India, for example, imports about 90 percent of its crude oil, making it vulnerable to rising energy prices during global crises.
Could the War Turn Into World War 3?
One of the most common concerns surrounding the conflict is the possibility of a global war.
While the current fighting is concentrated in the Middle East, the involvement of major global powers raises the stakes significantly.
The United States is a NATO member and maintains military alliances around the world. Iran, meanwhile, has strategic partnerships with countries such as Russia and China.
If those major powers were to enter the conflict directly, the situation could escalate into a much larger global confrontation.
However, many analysts believe a world war remains unlikely for several reasons.
First, nuclear-armed states are generally cautious about direct military conflict with each other because the risks are extremely high. Second, global economic interdependence means that large-scale wars would damage all major economies.
Instead, conflicts between major powers often remain limited or indirect.
Regional Risks and Proxy Conflicts
Although a world war may be unlikely, the risk of a wider regional war is very real.
Several armed groups and regional actors are already involved indirectly in the conflict. Iran maintains relationships with multiple militant groups across the Middle East, while Israel receives support from Western allies.
Proxy conflicts—wars fought through allied groups rather than direct military confrontation—are common in this region.
If fighting spreads further into Lebanon, Syria or Gulf states, the conflict could become far more complex and dangerous.
Impact on Global Markets and Industries
Financial markets are closely watching the war because geopolitical instability often affects investments and economic forecasts.
Stock markets in several regions have shown volatility as investors react to energy price shocks and political uncertainty.
Gold prices, often considered a safe-haven asset during crises, have also risen as investors seek protection from market instability.
Industries such as aviation, shipping and manufacturing are particularly sensitive to rising fuel costs.
For airlines and logistics companies, even small increases in oil prices can significantly increase operating expenses.
What Could Happen Next
Several possible scenarios could shape the future of the war.
One possibility is a short conflict lasting a few months, after which diplomatic negotiations reduce tensions. In this scenario, oil prices would likely stabilise once shipping routes reopen.
Another scenario involves a longer regional war, with continued missile attacks and economic disruptions across the Middle East.
The most serious scenario would involve additional global powers entering the conflict directly. That outcome could dramatically reshape global geopolitics and energy markets.
For now, world leaders and international organisations are calling for restraint and diplomatic engagement to prevent further escalation.
Why the Conflict Matters to the Entire World
Although the fighting is concentrated in the Middle East, the consequences of the war extend far beyond the region.
Energy prices, global trade routes, financial markets and geopolitical alliances are all influenced by the conflict.
For ordinary people, the effects may appear in rising fuel prices, increased transportation costs and higher inflation.
For governments, the crisis presents complex challenges involving energy security, diplomacy and economic stability.
The US–Israel Iran war is still unfolding, and its long-term consequences remain uncertain. What is clear is that the conflict has already reshaped global energy markets and heightened geopolitical tensions.
Whether the war remains a regional crisis or expands into a broader international confrontation will depend on diplomatic decisions, military strategies and the willingness of global powers to avoid further escalation.
