US-Iran Confrontation and Geopolitical Tensions: Economic and Maritime Disputes

The conflict began in September 2022 with US sanctions on Iran for alleged cyberattacks and drone use, escalating into direct military confrontation by March 2026. Following US-Israeli strikes on Iranian infrastructure in Tehran and Beirut, tensions intensified in the Strait of Hormuz. On April 23, 2026, Iran seized a vessel and launched fast-boat swarms in response to a US ultimatum to open the Strait, challenging US naval dominance. Although Israel and Lebanon extended a ceasefire following US-Iran talks, the Strait remained closed due to stalled negotiations. On April 27, Iran proposed reopening the Strait without a nuclear agreement, demanding the US lift its blockade; the US rejected this, with Senator Rubio stating the US could not accept Iranian control of the waterway. Consequently, the US formed a coalition to reopen the Strait, oil prices surged past $126, the Iranian rial collapsed, and the UAE withdrew from OPEC+ on April 28. In early May, the US launched 'Project Freedom' to guide ships through the Strait, but Iran warned this violated the ceasefire. After exchanges of fire and attacks on shipping, Secretary of State Mitt Romney declared the end of offensive operations, shifting to a defensive blockade. On May 10, the US suspended 'Project Freedom' citing progress in talks, but by May 15-16, negotiations stalled over Hormuz control and uranium export demands. Trump rejected Iran’s peace proposal on May 11, causing oil prices to surge. By May 22, peace talks collapsed over Hormuz control and uranium demands, with Trump asserting US control of the Strait and Iran claiming sovereignty. A peace framework emerged in June 2026. On June 15, a 14-point Memorandum of Understanding (MOU) was signed, including a $300 billion fund and sanctions relief, leading to the Strait reopening on June 18. However, disputes immediately emerged over maritime fees, with the US asserting toll-free passage and Iran claiming the right to charge service fees. On June 20, Iran closed the Strait again, citing Israeli strikes in Lebanon as a ceasefire breach; the US disputed this closure, noting ships continued to pass. Tensions flared again on June 26 when Iran attacked a cargo ship, prompting US strikes on Iranian missile and drone facilities, with both sides accusing the other of violating the ceasefire. By June 29, both sides agreed to pause attacks and resume technical talks in Qatar. The conflict oscillated between diplomatic mediation and military escalation through July and August. In late June, traffic dropped 80%, and by July 8, Trump declared the ceasefire over following Iranian attacks on US sites in Bahrain and Kuwait. The US reimposed a naval blockade and launched strikes, while Iran maintained control over the Strait. On August 27, US and Israeli forces attacked Iran, killing its Supreme Leader, marking a significant escalation. Despite this, a ceasefire agreement was announced on August 28, including provisions for free navigation, though Iran warned it would re-close the Strait if demands were unmet. The US claimed the Strait was cleared of mines, a claim Iran denied, asserting the Strait remained under its control. By late August and September 2026, the conflict entered a renewed crisis. On August 28, the US declared the Strait fully de-mined and open, while Iran and Oman agreed to a temporary corridor contingent on US lifting port blockades and paying compensation. Iran’s Foreign Ministry condemned US sanctions as 'economic terrorism.' By August 30, Iran declared the Strait completely closed, rejecting US claims of free passage. Oil prices surpassed $90 per barrel on August 31 as military exchanges resumed. By September 10, oil prices surpassed $100 amid escalating tensions, with Iran claiming attacks on US ships and oil tankers. The conflict did not remain in a continuous state of blockade from April to September; it oscillated with significant ceasefires and reopenings in June and August, ending in a renewed crisis after the US strike on Iran's Supreme Leader on August 27.
