Islamabad Memorandum of Understanding

The expiry of the 60-day timeframe stipulated in the Memorandum of Understanding has left the Middle East facing an exceptionally complex geopolitical vacuum, following the failure to forge a strategic agreement that would either defuse tensions or secure the full reopening of the Strait of Hormuz. This does not necessarily signal a sudden or dramatic collapse in negotiations. Rather, it raises a fundamental strategic question about what comes next. The region appears to be entering a calculated tactical transition from conventional diplomacy to a bitter phase of brinkmanship and mutual attrition between Washington and Tehran. As a result, maritime security in one of the world’s most vital waterways, through which approximately 21 million barrels of oil pass each day, equivalent to 20% of global oil consumption, together with around 20% of global liquefied natural gas trade, is increasingly subject to volatile political calculations.   Understanding US conduct in this crisis requires a careful examination of two seemingly contradictory, yet ultimately complementary, perspectives. President Trump’s insistence that there is no pressing timetable for resolving the crisis can be understood as part of a broader doctrine of tactical manoeuvre. Washington is effectively weaponising time to exert systematic economic pressure, sustained by the continuing naval blockade of Iranian ports and an intensification of sanctions. The strategic objective is to drive the Iranian economy towards breaking point and compel Tehran to make substantive concessions, while sparing the US the costs and risks of an open military confrontation. A parallel and more probing assessment, however, suggests that this tactical calm conceals a classic dilemma that sharply constrains US options. Full-scale military escalation would carry prohibitive security and financial costs, potentially driving maritime insurance premiums and energy futures into double-digit surges and placing global supply chains at risk. Yet acquiescing to Tehran’s terms would effectively subordinate international navigation to Iranian will. The current stalemate therefore amounts to little more than an enforced freeze, reflecting institutional frustration at the absence of effective surgical solutions.   On the other side of the strategic equation, Tehran has been far from a passive recipient of pressure. Instead, it has devised a counter-strategy that seeks to redefine the rules of engagement and weaponise geography as a potent source of negotiating leverage. In a particularly consequential move, Iran has succeeded, at least temporarily, in shifting international attention away from the complexities of its nuclear ambitions and uranium enrichment programme, while exploiting maritime chokepoints as an instrument of immediate coercive pressure. Tehran has transformed control over the flow of global trade through the Strait of Hormuz into a decisive bargaining instrument, demonstrating its ability to disrupt global geoeconomic calculations. Iran’s brinkmanship is clearest in the far-reaching conditions it has set for reopening the strait. Rather than limiting its demands to lifting the blockade, Tehran has raised the stakes by calling for the withdrawal of US forces and payment of financial compensation, while insisting on exclusive security control over the waterway and threatening to impose sovereign transit fees. Such maximalist escalation does not necessarily indicate an expectation that all these gains can be secured immediately and in a single settlement. Instead, it is intended to engineer a new geopolitical reality that affords Iranian negotiators greater room for trade-offs and forces the US administration onto the defensive.

The Middle East is witnessing a new geopolitical crisis centred on the Bab al-Mandab Strait after Yemen’s Houthi movement announced on 20 July 2026 the imposition of a naval blockade on the Kingdom of Saudi Arabia, in application of a principle the group terms “blockade for blockade”. The measure comes as a direct response to the restrictions Saudi Arabia has placed on the airports and ports lying under Houthi control, most notably Sanaa Airport and the ports of Hodeidah, and the decision followed a military escalation that included strikes on Sanaa Airport and the launching of missiles and drones towards Saudi airports.   Through this closure the Houthis seek to transfer the cost of the blockade from the Yemeni interior to a corridor vital to Saudi Arabia in the Red Sea and the Bab al-Mandab Strait, by closing the strait to vessels flying the Saudi flag or bound for the Kingdom. The closure also coincides with the disruption affecting the Strait of Hormuz as a result of the ongoing Iranian–American war, where the Revolutionary Guard’s interception rate of vessels transiting the strait has reached some 89 per cent. This has driven the Kingdom over the past four months to reroute its oil exports westwards, moving 4.5 million barrels of oil a day through a pipeline to the port of Yanbu on the Red Sea in order to provide an alternative passage, an increase of close to fivefold on the period before the war began.   On another front, Pakistan faces a complex strategic position as a result of these developments, since Islamabad is bound by a mutual strategic defence agreement with the Kingdom of Saudi Arabia signed in September 2025, alongside the presence of Pakistani forces stationed in the Kingdom. The agreement stipulates that any aggression against either state is deemed an aggression against the other, while Islamabad simultaneously performs the role of diplomatic mediator between the United States and Iran, having sponsored the signing of a ceasefire memorandum of understanding between the two parties in June 2026. In this context, Pakistani officials regard attacks on Saudi Arabia as a red line, which makes the naval blockade not merely a problem touching Saudi security but a direct test of Pakistan’s ability to balance its role as mediator with Tehran against its military commitments towards Riyadh. This tension places the Pakistani leadership before a clear challenge and raises an important question as to whether it will persist in its neutral position, or move towards a firmer stance should the crisis develop into a regional confrontation affecting the interests of its Saudi partner.
