Washington, Monday, 6 April 2026.
With a fifth of global oil supply blocked, President Trump’s Tuesday ultimatum to destroy Iranian power plants threatens severe disruptions across international energy markets and supply chains.

The “Power Plant Day” Ultimatum

In a stark escalation of rhetoric, U.S. President Donald Trump has set a definitive deadline of Tuesday, April 7, 2026, at 8:00 P.M. Eastern Time, for Iran to reopen the vital shipping lane [3][4][6]. During an eight-minute interview with The Wall Street Journal on Sunday, Trump warned that if Iranian leaders fail to comply, they will “lose every power plant and every other plant they have in the whole country” [2]. He amplified this threat on his Truth Social platform, dubbing the impending deadline “Power Plant Day, and Bridge Day,” and delivering an expletive-laden warning that Iran would be “living in Hell” if the strait remains blocked [3][4][8].

Escalating Tit-for-Tat Infrastructure Strikes

The Tuesday deadline arrives on the heels of a highly volatile weekend that saw both sides intensify their attacks on critical energy and military infrastructure. On Sunday, April 5, Israel executed a powerful strike on a major petrochemical plant at Iran’s South Pars natural gas field [5]. The U.S. and Israel also conducted targeted strikes in Tehran that resulted in the death of Major General Majid Khademi, the intelligence chief of Iran’s Revolutionary Guards [5]. In retaliation, Iran expanded its offensive against Gulf energy infrastructure, launching drone and missile strikes that caused severe damage to oil and petrochemical facilities in Kuwait, Bahrain, and the United Arab Emirates [3][5]. Furthermore, an Iranian ballistic missile struck a residential building in Haifa, Israel, leaving four people dead [3][5].

Diplomatic Whispers Amidst the Crossfire

Despite the aggressive posturing, back-channel diplomacy appears to be operating in overdrive. Regional mediators have presented a proposal for a 45-day ceasefire to both the U.S. and Iran [5]. In an interview with Fox, President Trump suggested that a diplomatic deal with Iran could be reached as early as Monday, even as he simultaneously threatened to rain down destruction if his Tuesday deadline is ignored [9]. Trump is scheduled to hold a White House news conference on Monday afternoon to provide updates on the conflict and detail the successful rescue of a U.S. F-15 fighter jet crew member who was downed over Iran last week [8][9].
