Geopolitical Conflict Threatens Yet Another Shipping Choke Point

 | Apr 18, 2024 08:03

It's a stark fact: more than 80% of global goods trade is transported by sea. And any disruption in maritime trade can have a profound impact on the worldwide economy. The latest potential flashpoint is the Strait of Hormuz. It's a vital artery that carries around a fifth of the world's oil. It's been at the centre of numerous geopolitical tensions for many years. Any disruption could have yet another negative economic impact on the global economy, hampering vital trade routes and lengthening transit times, resulting in production delays and higher inflation.

But the Strait is not the only place where there's deep concern about security.

For some time now, the Strait of Bab el-Mandeb-Suez Canal, which handles around 15% of global maritime trade, has seen significant disruption due to attacks by Houthi rebels on ships in the region. The Red Sea is still largely being avoided, with daily transits down two-thirds year-on-year, according to IMF PortWatch data. On the other side of the globe, a drought at the Panama Canal, which handles 5% of global maritime trade, is slowly improving as daily transits have risen to 27 in March from 24 in January and 22 in December 2023. Yet, capacity is still off the normal daily average of 34-40 transits, a level currently only expected to be reached again by 2025. And next to this, shallow waters in the world’s main inland shipping waterways could easily return over the course of this year.

Due to the mounting tension in the Middle East, those risk-laden waters have spread from the Red Sea to the Gulf of Aden, and the vital Strait of Hormuz could be caught up in it too. It was only days ago that Iranian forces seized the MSC Aires container vessel. We know from all the disruption in the Red Sea that elevated risks could quickly impact trade routes once seafarers and cargo are threatened and insurance risk premiums go up. As such, trade has become increasingly politicised. It's worth noting here that another maritime area in the scope of geopolitical risks is the Taiwan Strait, which is a gateway to large Chinese ports.

When it comes to international trade, it's difficult to quantify the financial effect of one or two events, whether they're geopolitically related or not. That said, you may recall the blockage of the Suez Canal by a container ship, Ever Given, in 2021. That led to an estimated loss of 0.2 to 0.4 percentage points in global trade. Low water levels in the Rhine in Germany had a negative impact of 0.3% on GDP numbers due to higher transport and trade costs and production delays.
