The stability of global supply chains is under threat as the world’s leading shipping companies are rerouting their vessels away from the Red Sea, in response to increasing attacks by Houthi rebels in Yemen.
These attacks have led to a significant shift in maritime traffic, avoiding one of the most crucial and busiest shipping lanes globally.
The Houthis, showing solidarity with Hamas, have targeted ships they claim are bound for Israel, although the destinations of all the attacked ships remain unconfirmed.
Recent Developments: The intensification of these assaults began with the onset of the Israel-Hamas conflict in October.
The Houthi group, supported by Iran, has been employing drones and missiles to attack international ships passing through the Bab al-Mandab Strait.
This narrow waterway, only 20 miles wide, lies between Eritrea and Djibouti in Africa and Yemen on the Arabian Peninsula, serving as a pivotal route for ships heading north towards Egypt’s Suez Canal.
In an attempt to mitigate the risk of further attacks, major shipping companies like Mediterranean Shipping Company and Maersk have now chosen to take a longer, alternative route.
This detour navigates around the Cape of Good Hope at the southern tip of Africa, then proceeds up the continent’s west coast, significantly extending travel times and potentially impacting global supply chains.
BP has also paused all shipments of oil through the Red Sea, blaming the “deteriorating security situation”.
The longer journeys will add at least 10 days shipping times and cost companies millions of dollars.
Why is this shipping route so important?
Any ship passing through the Suez Canal to or from the Indian Ocean has to come via the strait of Bab al-Mandab and the Red Sea.
The Suez Canal is the quickest sea route between Asia and Europe and is particularly important in the transportation of oil and liquefied natural gas (LNG).
About nine million barrels of oil per day were shipped through the Suez Canal in the first half of 2023, according to freight analytics firm Vortexa.
Analysts at S&P Global Market Intelligence said nearly 15% of goods imported into Europe, the Middle East and North Africa were shipped from Asia and the Gulf by sea. That includes 21.5% of refined oil and more than 13% of crude oil.
But it is not just about oil. Container ships carry all sorts of consumer goods seen in the shops including TVs, clothes, trainers and sports equipment.
What is the impact on consumers?
It is inevitable that supply chains will be affected due to ships being diverted away from the Red Sea, but consumer goods “will face the largest impact”, according to Chris Rogers, head of supply chain research at S&P Global Market Intelligence, though he does note the current disruption has occurred “during the off-peak shipping season”.
Delays to products reaching shops can be expected, with container ship journeys expected to take at least 10 days longer due to the Cape of Good Hope route adding about 3,500 nautical miles.
The extra distance will also cost companies more. Shipping rates have risen 4% in the past week and those costs could be passed on by businesses to customers.
However, rates still remain much lower than last year, and are far below the levels seen in 2021, when freight charges soared in line with demand as Covid restrictions were eased.
There are also fears the disruption could push up oil prices.
A rise in oil prices, a key ingredient in car fuel, can lead to higher prices at the pumps and also drive higher inflation. Inflation, which measures the pace of price rises, has been falling in the UK and is currently 4.6%.
When it comes to shipments of LNG being disrupted, even if wholesale energy prices rise, any increases would not feed through to domestic bills until April 2024 at the earliest.
This is because the energy price cap, which limits the amount suppliers can charge, has already been set for January.
Is moving freight by sea the only option? Mr Rogers says transporting goods by rail instead would require “crossing Russia”, which is under economic sanctions due to invading Ukraine, while “trucking from the Gulf to Israel may only offset around 3% of shipping”.
What is being done in response?
The attacks have led the US to launch an international naval operation to protect ships in the Red Sea route, and countries including the UK, Canada, France, Bahrain, Norway and Spain have joined.
US defence secretary Lloyd Austin held a virtual meeting with ministers from more than 40 countries on Tuesday, and called on more nations to contribute to efforts to keep shipping safe in the region.
But some shipping companies are reluctant to immediately start using the route again despite increased security.
Maersk and Hapag-Lloyd, which have both have ships that have been attacked by Houthi rebels, welcomed the extra measures but said it is difficult to determine when they would go back to using the Red Sea, meaning there could be disruption for some time.
