Trump's 48-Hour Iran Ultimatum Deadline Passes as Middle East Crisis Deepens
Washington, 22 March 2026
President Trump’s Saturday ultimatum demanding Iran reopen the Strait of Hormuz within 48 hours has expired, with no indication Tehran has complied. The deadline passed as Israeli forces conducted strikes in Tehran and Iran launched ballistic missiles at Israeli cities, wounding over 100 people. The crisis has now entered its fourth week, with oil prices remaining elevated at $112 per barrel and global energy supplies severely disrupted. Six oil shipments to Australia have been cancelled, while Sri Lanka raised fuel prices by 25 per cent. Trump threatened to ‘obliterate’ Iranian power plants, whilst Iran warned it would target all US energy infrastructure if attacked.
Escalation Despite Diplomatic Ultimatum
This latest escalation builds upon previous tensions where Trump had called on Britain and allied nations to deploy warships after Iran’s newly appointed Supreme Leader Mojtaba Khamenei vowed to maintain the shipping blockade. The crisis has already seen 16 tanker attacks since late February, with oil prices climbing above $100 per barrel [GPT]. Trump’s Saturday ultimatum, issued on 21 March 2026, demanded Iran “FULLY OPEN, WITHOUT THREAT, the Strait of Hormuz, within 48 HOURS from this exact point in time” or face the destruction of Iranian power plants [1]. However, Iran’s military operational command Khatam Al-Anbiya responded defiantly, warning that “if Iran’s fuel and energy infrastructure is violated by the enemy, all energy, information technology and desalination infrastructure belonging to the US and the regime in the region will be targeted” [1].
Iranian Missile Strikes Wound Over 100 in Israel
As Trump’s deadline approached, Iran launched its most devastating attack yet on Israeli territory. On Saturday, 21 March 2026, Iranian ballistic missiles struck the southern Israeli cities of Arad and Dimona, wounding approximately 100 people [1][2]. The missile that hit Arad alone wounded 84 people [1]. These strikes represented a significant escalation in Iran’s capabilities, with the country demonstrating its ability to reach deep into Israeli territory with precision-guided munitions. The attacks came as part of Iran’s broader strategy to maintain pressure on both Israel and the United States whilst the Strait of Hormuz remains effectively closed.
Israeli Retaliation and Regional Spillover
Israel responded swiftly to the Iranian missile barrage, with the Israeli military announcing on Sunday, 22 March 2026, that it was conducting strikes in Tehran [1]. The escalation has begun to spill over into neighbouring countries, with Saudi Arabia detecting three missiles launched towards Riyadh on Sunday—one was intercepted whilst two fell in an uninhabited area [1]. Iran also demonstrated its long-range strike capabilities by launching two ballistic missiles with a range of 4,000 kilometres at the US-British military base at Diego Garcia in the Indian Ocean on Saturday [1][4]. This marked the first time Iran had deployed such long-range missiles since the conflict began on 28 February 2026 [4]. Additionally, a drone attack targeted a military base near Baghdad International Airport on Sunday [1], whilst the United Arab Emirates defence ministry reported intercepting and destroying three Iranian drones in the eastern region [1].
Global Economic Ramifications Intensify
The continuing crisis has sent shockwaves through global energy markets, with Brent crude oil reaching $111 per barrel on 19 March 2026 [4] and remaining at $112 per barrel as of Friday, 20 March 2026 [5]. The impact is being felt worldwide, with Sri Lanka raising fuel prices by 25 per cent on Sunday, 22 March 2026—regular petrol increased to 398 rupees ($1.30) per litre, and diesel rose to 382 rupees [1]. Australia faces particular challenges, with six oil ships bound for the country having been cancelled on Sunday [1], and disruptions expected for oil shipments arriving in late April and May [1]. The S&P 500 dropped 1.5 per cent on Friday due to the war’s impact on energy markets [5], demonstrating how the Middle East crisis is reverberating through global financial systems. Since the US and Israeli military strikes began on 28 February 2026, oil prices have jumped approximately 50 per cent [3].
Mixed Signals from Washington
Despite issuing the ultimatum, President Trump has sent contradictory signals about the conflict’s direction. On Friday, 20 March 2026, Trump stated he was considering “winding down” the Iran war, claiming the US is “getting very close” to meeting its objectives [3][5]. He also declared that “from a military standpoint, they’re finished” when referring to Iran [4][6], yet simultaneously announced the deployment of approximately 2,500 Marines and additional warships to the region [3][5]. Adding to the confusion, the Trump administration lifted sanctions on Iranian oil that was already at sea on Friday [5], with Representative Nancy Mace of South Carolina criticising this as “bombing Iran with one hand and buying Iran oil with the other” [5]. The Pentagon has requested an additional $200 billion from Congress to fund the conflict [3][5], even as Trump suggested other nations should take responsibility for policing the Strait of Hormuz, stating “The United States does not!” use the waterway [3][5].
