Supply Chain Disruption

The United States–Israel–Iran war, which began with a set of vaguely defined objectives including regime change in Iran and the dismantling of its missile and nuclear capabilities, now appears to be shifting toward a different set of priorities. Iran has managed to internationalise the conflict in a way that has redirected attention toward containing the scale of global economic disruption. Put simply, the focus is increasingly on securing the flow of oil amid what is being described as one of the most severe energy crises in modern history. Much of the world’s attention has centred on the Strait of Hormuz, and rightly so. This vital shipping lane accounts for roughly 20% of global liquid petroleum consumption, as well as a significant share of global liquefied natural gas trade (LNG). However, with the Iran-backed Yemeni Houthis now entering the conflict, the risks facing regional oil exports and maritime routes have intensified further. As the de facto controllers of the Bab al-Mandeb Strait, the Houthis are in a position to disrupt shipping through the Red Sea and the Gulf of Aden.   This raises several critical questions. Why have the Houthis chosen this moment to enter the war? Under what conditions might they escalate their involvement? And what would be the consequences of a closure of the strait?

In April 2025, the Trump administration stunned global markets by announcing a sweeping tariff expansion under the International Emergency Economic Powers Act (IEEPA), introducing a flat 10% universal tariff on all imports. This move, framed as a national economic emergency response, immediately triggered global trade uncertainty and diplomatic friction. The policy marked a significant escalation of Trump’s protectionist agenda, signalling a break with multilateralism and targeting long-standing trade imbalances with strategic rivals and allies alike. We found that the United States (U.S.) trade structure is deeply imbalanced, with persistent deficits concentrated in sectors essential to industrial production, such as machinery, electronics, and vehicles. These deficits have exposed the U.S. to retaliatory measures from key trade partners—particularly China, Canada, and the EU—who have calibrated their responses to hit politically and economically sensitive export categories. Tariffs have initiated a multi-channel inflationary shock: direct consumer price increases, rising intermediate input costs, and cascading pressures on logistics and wages. The compounded effect has resulted in a net consumer price index (CPI) increase of approximately 1.2%, with higher spikes in key durable goods. Global supply chains are beginning to reconfigure.   The automotive sector, in particular, has seen disruption in bilateral flows with traditional partners, creating openings for new logistical nodes. The UAE stands out as a beneficiary, attracting redirected FDI and becoming a strategic re-export and final assembly hub. Collectively, these findings underscore a paradox: while the policy aims to reduce dependency and correct trade imbalances, it simultaneously accelerates external retaliation, domestic cost pressures, and global fragmentation in trade infrastructure.
