6 critical places in the world that could make your life much more expensive

Around 10 minutes to read

You fill up your car, buy bread and order a new washing machine. Their price can depend on whether a ship thousands of kilometres away gets through a strip of water only a few kilometres wide. Or whether a small country has had enough rain.

More than 80% of international trade in goods, by volume, travels by sea. Much of that traffic uses straits and canals you could almost overlook on a map. [1]

These are chokepoints. Imagine traffic from several motorways converging on a single tunnel. An accident inside creates queues far beyond it.

At sea, the queue contains oil, fertilisers, grain and industrial materials. A detour can mean sailing around an entire continent—if an alternative exists at all.

1. Hormuz: oil, fertilisers and helium through one narrow gateway

Where it is: between Iran to the north and Oman to the south. It connects the Persian Gulf to the Gulf of Oman and, beyond that, the Arabian Sea.

How narrow it is: roughly 34 kilometres at its narrowest point. The actual shipping lanes are much narrower: about 3.2 kilometres in each direction, with a separation zone between them. Tankers cannot use the entire width as an open motorway. [2]

Inside the Gulf lie the ports of several major energy exporters. In 2024, according to the EIA, oil and petroleum products passing through Hormuz represented roughly one-fifth of global consumption. Around one-fifth of global trade in LNG, or liquefied natural gas, also passed through. These are figures for a specific period, not a description of today's traffic. [3]

But oil is only the most visible part of the story. Hormuz is also a gateway for materials whose absence can disrupt food production, chipmaking and scientific and medical equipment.

Sulphur: an overlooked link between oil and your lunch

According to the IEA's 2026 analysis, roughly half of global seaborne sulphur trade passes through Hormuz. That means half of the volume traded by sea, rather than half of all sulphur produced. [20]

Sulphur is recovered during oil and natural gas processing. It is used to make sulphuric acid, an important input for phosphate fertilisers. Its role goes beyond being a crop nutrient: it also enables the manufacture of other fertilisers. [29][30]

If deliveries stall, trouble can spread from a chemical plant to a farm. Expensive or unavailable fertiliser can raise farmers' costs or reduce applications. At a crucial stage of crop growth, a shipment arriving three months late cannot make up for the missed timing. The effect on harvests and food prices may emerge in the following season.

Sulphuric acid is also important in processing certain metals, including copper and nickel. A sulphur shortage can therefore raise costs in battery and electrical-equipment supply chains too. [20]

Helium: a small market with a potentially irreplaceable input

According to the USGS, Qatar produced roughly 35% of the world's helium in 2024. Helium is used in semiconductor manufacturing, laboratories and cooling superconducting magnets in MRI scanners. [22][23]

Qatari supplies are also shipped through Hamad Port in specialised containers aboard container vessels. Leaving the Persian Gulf then requires passage through Hormuz. The dependence therefore involves both production and specialised logistics. Qatar's share of production cannot automatically be treated as the same share of global helium passing through the strait. [25]

For cooling near 4 kelvin, roughly −269°C, helium has no direct substitute as a liquid coolant. Some other uses do have substitutes, and modern MRI systems can greatly reduce helium consumption. A shortage would not automatically stop all scans, but could complicate operations, servicing or deliveries of equipment that needs it. [24][23][31]

For a particular process, such a disruption can be harder to solve than an oil shortage: more fuel from elsewhere cannot replace a missing industrial gas. That does not establish that helium has a greater economy-wide impact than oil.

The list continues. The region also exports urea and ammonia for fertilisers, petrochemical feedstocks and aluminium. Hormuz connects energy, food and industrial risks. [21][32]

Who has power over the passage: Iran and Oman are the coastal states. Iran can threaten shipping militarily; safe passage also matters to other exporters and buyers. An international route is not one state's private gateway.

A ship inside the Gulf cannot simply turn and sail around the strait. Pipelines help with only part of oil exports; they cannot replace a ship carrying helium, sulphur or fertiliser. That is why trouble in Hormuz can reach your petrol station, groceries and electronics. [3]

2. Malacca: where energy meets Asia's factories

Where it is: between the Indonesian island of Sumatra and the Malay Peninsula. At its southeastern end it joins the Singapore Strait; together, they form a crucial route between the Indian Ocean and the South China Sea.

How narrow it is: the critical constriction near Singapore, in the Phillips Channel, is roughly 2.7 kilometres wide. When this width is quoted for Malacca, it refers to the adjoining Singapore section, rather than the entire long strait. [6]

This is a short sea route between Middle Eastern energy suppliers and major Asian markets. According to the EIA, around 23.2 million barrels of oil and petroleum products passed through Malacca each day in the first half of 2025, representing about 29% of global seaborne trade in those commodities. That is not the same as 29% of all global trade. [7]

Who has power over the passage: Indonesia, Malaysia and Singapore are the main coastal states of the combined route. They cooperate on navigational safety and protection of the marine environment. China is a major user of this route, but dependence on a strait does not mean ownership or administration of it. [8]

A narrow, busy route creates risks of collisions, groundings and pollution. Piracy and armed robbery are also security concerns. Alternatives exist, including Indonesia's Sunda and Lombok straits, but rerouting means a longer journey and greater demands on shipping. [6]

Malacca is also relevant beyond energy. Indonesia and Malaysia are major palm oil exporters. For European shipments from ports using this route, a disruption can complicate supplies of food and chemical inputs. Not every shipment from the region must pass through Malacca: the port's location and the destination determine its route. [28]

The reverse flow matters to your wallet too: Asian factories need energy and materials to manufacture goods for Europe. If both inputs and outward shipping become more expensive, costs can rise at both ends of the chain. Some detours also pass through other straits; an alternative route may struggle to absorb all the diverted traffic without delays.

3. Bab el-Mandeb: a gateway ships can abandon without anyone locking it

Where it is: between Yemen on the Arabian Peninsula and the African coast near Djibouti and Eritrea. It connects the Red Sea to the Gulf of Aden and, beyond that, the Indian Ocean.

How narrow it is: roughly 29 kilometres at its narrowest point. Perim Island also divides the strait, so large ships use specific navigational corridors. [4]

For an Asia-to-Europe voyage through Suez, Bab el-Mandeb is the southern entrance. A ship must pass through it first, then travel along the Red Sea before entering the Egyptian canal. Without a safe southern entrance, the northern shortcut loses much of its value.

Who has power over the passage: several states border the strait, but shipping safety also depends on armed forces along Yemen's coast. The Houthis, an Iranian-backed Yemeni movement, have shown that attacks on ships can influence decisions by global shipping companies. That does not mean they legally own the entire strait. It means they can make using it dangerous. [5]

After attacks on merchant ships began in November 2023, shipping companies started rerouting vessels around Africa. On some routes, that added roughly one to two weeks at sea. [5]

This is the heart of the problem: a chokepoint does not have to be physically blocked. It only has to become too risky to use. A shipping company must protect its crew, vessel and cargo. An insurer prices the risk. A customer needs to know when the goods will arrive.

European electronics shops are not the only ones facing a bill. Food supplies to countries around the Red Sea are also exposed. In March 2024, the FAO warned that Yemen imported roughly 90% of its staple cereals and that shipping disruption could raise prices and reduce food availability. [26]

A company can fly in delayed components at a high cost. Replacing a huge grain shipment with air freight is a different economic proposition. The same threat at sea can mean a more expensive product in one place and a serious food-supply problem in another.

Bab el-Mandeb shows that influencing global trade does not require ownership of a canal. The ability to threaten ships where they need to pass can be enough.

4. Suez: one ship showed the world what a shortcut is worth

Where it is: in Egypt, between the Mediterranean and the Red Sea. It separates the Sinai Peninsula from the rest of the country.

How narrow it is: the canal is roughly 193 kilometres long, with many sections measured in hundreds of metres across. The exact width depends on the location and the depth at which it is measured. It is not a uniformly wide channel, and part of the route has parallel branches. [9]

Suez allows ships travelling between Europe and Asia to avoid sailing around Africa. Its value lies in the distance and time saved. According to UNCTAD, it handled roughly 12–15% of global trade in 2023. [10]

Who has power over the passage: Egypt, through the Suez Canal Authority, which manages operations and collects transit fees. But Egypt alone cannot guarantee the safety of the entire route: a ship coming from the Indian Ocean also needs safe passage through Bab el-Mandeb and the Red Sea.

In March 2021, the container ship Ever Given ran aground in the canal and blocked it for six days. One accident halted passage and created a queue of waiting vessels. [11]

Containers of consumer goods and components travel through this shortcut alongside energy and agricultural commodities. A disruption is about more than expensive purchases: a factory might lack a cheap component needed to finish a costly product. The missing part's price does not reflect the value of production it can halt. [27]

Sailing around Africa uses more time and fuel, and each ship completes fewer voyages. Delayed cargo can also bunch up at ports after shipping resumes. Reopening the canal does not immediately restore the entire schedule.

Egypt's SUMED pipeline can take over some oil transport. It is not a bypass for containers, grain or LNG. Replacement infrastructure must suit the cargo concerned. [7]

Suez and Bab el-Mandeb are two chokepoints on one important route. Their shares of trade cannot simply be added together: much of the same cargo passes through both.

5. Bosphorus: hundreds of metres between the Black Sea and the wider world

Where it is: in Türkiye, running through Istanbul. It connects the Black Sea to the Sea of Marmara. To reach the Mediterranean, a ship must then also pass through the Dardanelles.

How narrow it is: roughly 700 metres at its narrowest point. Large ships navigate a winding route with currents and local traffic in the middle of a major city. [16][17]

The Bosphorus is part of the Black Sea's only natural maritime connection to the world's oceans. It is therefore essential to exports from Black Sea ports. Oil is only part of the story: the region is also important to trade in grain and other agricultural products.

The historic Black Sea Grain Initiative illustrates the scale of food shipments. From 2022 to July 2023, it enabled approximately 32.9 million tonnes of food commodities to leave Ukrainian ports. It was a specific agreement for a particular period, rather than a permanent corridor guaranteeing every future shipment's safety. [18]

Who has power over the passage: Türkiye. Transit is governed by the 1936 Montreux Convention, which distinguishes merchant ships from warships. Ankara has significant powers, but the rules cannot be reduced to a claim that it can stop all trade without restriction. [17]

Russia and Ukraine have a major stake in Black Sea routes. Russia's war against Ukraine has shown that shipping can also be threatened outside the Bosphorus itself, through attacks on ports or disruption of navigational safety. Turkish control of the strait therefore does not mean control over everything happening in the Black Sea. [19]

Oil matters too, including supplies from Kazakhstan shipped through Black Sea ports. The EIA identifies Kazakhstan as the largest oil exporter through the Turkish Straits in the first half of 2025. The Bosphorus is therefore more than a Russia–Ukraine story: disruption can affect exports from a country with no Black Sea coastline at all. [7]

There is no simple maritime detour. Some cargo can move overland or through other ports, but that requires extra handling, infrastructure and spare capacity. For grain, higher costs can affect flour and, through animal feed, meat and eggs.

Restrictions on warship passage are also distinct from merchant-shipping safety. Closing the straits to certain warships does not automatically ban grain exports; attacks on ports can disrupt exports even while the Bosphorus remains navigable. [17][19]

6. Panama: a global shortcut that depends on rain

Where it is: in Panama, in Central America. It connects the Atlantic Ocean, via the Caribbean Sea, to the Pacific Ocean.

How narrow it is: here, the precise dimensions of the locks are also a constraint. The larger Neopanamax lock chambers are 55 metres wide and 427 metres long. For a large vessel, this is a passage with very definite boundaries. [12]

The Panama Canal avoids a long voyage around South America. It is important to transport between the oceans, including trade routes linking American ports with Asia.

Who has power over the passage: Panama, through the autonomous Panama Canal Authority. The canal has been under Panamanian administration since the end of 1999. Operating a port at its entrance is not the same as controlling the canal itself. [13]

Its most interesting weakness, however, is a natural one. Unlike at Suez, ships in Panama must overcome differences in water level. Locks raise and lower them, using fresh water from local water sources. That water also serves the population. [14]

During the drought of 2023 and 2024, the operator had to restrict traffic and ships' permitted draught. Later improvements in conditions allowed some restrictions to be eased. The episode shows why canal capacity cannot be treated as a fixed number independent of the weather. [15]

A lower permitted draught—the depth a ship extends below the waterline—can mean carrying less cargo per vessel. Fewer available transits mean waiting or looking for another route. Either way, a cheap shortcut becomes a more expensive service.

Panama carries more than containers. Shipments of LPG, particularly propane and butane, from the US to Asia are important too. LPG is different from LNG: it serves as fuel and petrochemical feedstock. In 2023, the EIA documented how canal queues raised freight rates for large gas carriers and reduced available capacity elsewhere. [33]

The impact on Central Europe is often less direct than at Suez, but each country does not have a separate fleet. A vessel spending weeks waiting or on a detour is unavailable for its next voyage. Rerouting through Suez helps only if the Red Sea route is safe too.

Panama reminds us that an alternative on a map may be unusable when needed. When one shortcut faces water restrictions and another security threats, the problems compound.

How trouble at sea reaches your shopping bill

You need not live by the sea to pay for its problems. Even local products may need imported materials, components or packaging.

Costs spread through freight, insurance, inventories and replacement supplies. A critical material shortage can disrupt production itself. Making a product more expensive and making it temporarily impossible to manufacture are different problems.

Not every disruption immediately raises every price. Stocks, contracts, alternative suppliers and recycling can help. Helium recovery can reduce dependence; for fertilisers, the timing of application also matters. Doubling freight charges does not double a washing machine's price, and a material's share of global trade does not by itself determine how replaceable it is.

These places combine narrow passages, huge cargo flows and limited alternatives. Oil has a vast market; a small industrial-gas shipment can still be decisive for a particular factory. Fertiliser disruption may show up in the next harvest.

A tanker waiting outside a strait or a drought in Panama can also be the beginning of a bill you pay later.
