US-Israel War on Iran Escalates: Nearly 2,000 Targets Struck as Global Energy Crisis Deepens
The US-Israel military campaign against Iran has intensified dramatically, with the US military reporting strikes on nearly 2,000 targets inside Iran, while the closure of the Strait of Hormuz has triggered a global energy crisis that is reshaping economies and political calculations around the world.
The conflict, which has drawn in multiple regional actors and sent shockwaves through global financial markets, shows no immediate signs of resolution despite diplomatic efforts from several nations. Oil prices have surged past $100 a barrel, and the disruption to global energy supply chains is being felt from London to Tokyo.
Background
The war escalated following a series of Israeli strikes on Iranian nuclear facilities, including confirmed damage to the Natanz site as verified by the International Atomic Energy Agency (IAEA). The coordinated US-Israeli campaign, which began on 28 February 2026, was stated to have twin objectives: dismantling Iran's nuclear and ballistic missile programmes and forcing a change in the country's leadership. Iran responded with missile and drone attacks on US and Israeli bases throughout the Gulf region, drawing the United States into direct military confrontation.
A pivotal moment came with the reported death of Supreme Leader Ayatollah Ali Khamenei in the initial wave of airstrikes, with reports emerging that Mojtaba Khamenei is being positioned as his successor. The conflict has also spilled into Lebanon, where Israeli strikes have intensified, displacing at least 30,000 people and deepening the humanitarian toll across the region.
The International Energy Agency (IEA) described the Strait of Hormuz closure as the "largest supply disruption in the history of the global oil market," with approximately 20% of the world's seaborne oil trade passing through the waterway. To mitigate the impact, the IEA coordinated the release of 400 million barrels of oil from strategic reserves held by member states.
Key Developments
The Iranian Red Crescent Society has reported at least 787 fatalities as a result of the conflict, with the human cost continuing to mount on all sides. Brent crude oil surged from around $70 per barrel before the conflict to over $100 a barrel, at one point reaching a peak of $126 per barrel, while UK wholesale natural gas prices saw a staggering 75% increase between late February and March 2026.
In a national address, US President Donald Trump justified the military campaign, claiming strategic objectives were "nearing completion" and suggesting the conflict could be over "very soon" through indirect talks. However, the war has created a significant rift among his conservative base and drawn widespread international condemnation. Oman and Pakistan have played key roles in mediating indirect talks between Washington and Tehran, with a conditional two-week ceasefire announced on 8 April 2026 to allow for negotiations on a more lasting agreement.
The United Nations Security Council passed a resolution on 11 March 2026, co-sponsored by the UK, demanding an end to Iranian attacks on Arab states and reaffirming freedom of navigation through the Strait of Hormuz. China and Russia abstained from the vote, underscoring the deep geopolitical fault lines the conflict has exposed.
Why It Matters
The conflict represents the most significant military escalation in the Middle East in decades and has profound implications for global energy security, international law, and the stability of the broader region. The IEA's characterisation of the Strait of Hormuz closure as the largest supply disruption in oil market history is not hyperbole — the economic shockwaves are being felt in every corner of the globe.
For ordinary households, the consequences are immediate and painful. Petrol prices in the UK rose by 14 pence per litre in the month following the conflict's outbreak, while diesel surged by 29 pence per litre. The Bank of England halted anticipated interest rate cuts, holding its main rate at 3.75% in March 2026, with analysts warning of potential hikes ahead. UK GDP growth forecasts for 2026 have been slashed from 1.1% to as low as 0.4% by some economists. The conflict has also reignited urgent debates about energy security and the need for alternative supply routes that reduce dependence on the Gulf.
Local Impact
For households and businesses across the United Kingdom, the economic consequences of the Iran conflict are already biting hard. Rising energy bills, higher fuel costs, and increased inflation are squeezing family budgets at a time when many were only beginning to recover from the cost-of-living pressures of recent years. The Bank of England's revised inflation forecast — up from an expected 2% to between 3% and 3.5% for the second and third quarters of 2026 — signals that relief is not imminent. Northern Ireland, which relies heavily on imported energy and has limited domestic generation capacity, faces particular exposure to global price shocks of this magnitude. Businesses dependent on fuel and logistics are already reporting significant cost increases, with some warning of job losses if the situation does not stabilise.
What's Next
Diplomatic efforts to de-escalate the conflict and reopen the Strait of Hormuz are ongoing, with the conditional ceasefire announced in April offering a fragile window for negotiation. The outcome will have far-reaching consequences for global energy markets, the broader geopolitical order, and the economic wellbeing of millions of people far beyond the Middle East.
