Russell: The impact of the closure on Chinese EVs is not limited to oil, but also extends beyond it.

The Indian diet cola consumer and the buyer of an electric vehicle may appear to have little in common. But they both face the risk of being affected by the closure of the Strait of Hormuz.

The world economy will be affected by the second and third round effects of the closure of the narrow waterway. Already, the price of refined fuels like diesel and gasoline has increased and inflation is a result.

Electric vehicles (EVs), which allow users to reduce their dependence on fossil fuels, are considered by many to be a big winner in the current conflict between Iran and the United States.

EVs, however, are still exposed to the Strait of Hormuz because the manufacturing of their batteries relies on sulphuric acids. This is a component that is used in the extraction of nickel and lithium.

The high-pressure acid-leach method is essential for the extraction of battery-grade Nickel from ore in mines in Indonesia, which is the world's largest producer of metal.

Copper and lithium are also produced in Australia.

Before the U.S.-Israeli attack on Iran on February 28, about half of the world's seaborne sulphur passed through the Strait of Hormuz and largely went to Asia.

Sulphur is produced as a byproduct when crude oil or gas is refined into fuels. Middle East countries like the United Arab Emirates, Saudi Arabia, and Kuwait are major suppliers of raw materials used to produce sulphuric acids.

Bulk carriers usually transport sulphur, but volumes have fallen since the Iran conflict began. According to Kpler's commodity analysts, only 30,000 tons of metric sulphur made it through in April and 188,000 tons in March.

Kpler reported that this was a decrease from the average of 1.27 millions tons per month during the three months before the beginning of the conflict.

Delivered prices in Asia have risen by 50% since the beginning of the war, to $880 per ton.

Sulphuric Acid costs will rise for nickel, lithium, and copper miners. But the greater concern is that there could be a shortage of sulphuric acids.

The risk is that some miners may have to cut back production if they cannot obtain enough sulphuric acids.

RISE IN CONCERN

The sulphuric-acid supply is becoming increasingly difficult to secure on a long-term basis, according to several mining executives from Indonesian and Australian companies that attended the Asian Battery Raw Materials Conference held in Hanoi last month.

China's EV makers and battery manufacturers are vulnerable to any disruption in the supply of lithium as well as nickel from Australia.

Alternatives to sulphuric acids are available, but are not suitable for producing battery-grade Nickel. For copper and lithium, they require more energy to produce smaller volumes.

The processing of metals may not be a crisis yet, but the closer we get to that point the longer the Strait of Hormuz is effectively closed.

This raises the issue of what Beijing will do if the threat to its EV industry and battery industries is more than just a remote possibility.

The logical next step would be to increase pressure on Iran, its ally, and Donald Trump in the United States to reach an accord that at least reopens all traffic through the Strait of Hormuz.

Other impacts are already felt, besides crude oil and LNG.

Before the Iran?war, about 8% of the global aluminium supply passed through the Strait of Hormuz. This has now largely ceased.

Kpler data shows that 20,000 tonnes of lightweight metal left the Strait of Hormuz in April. This is down from a previous average of 1,26 million tons during the three months before the beginning of the war.

Loss of these cargoes have tightened the supply of aluminium in India. This has led to a shortage of Diet Coke which is sold only in aluminum cans.

This is a 'inconvenience' for Diet Coke consumers, but it also shows how shortages can occur in unexpected places, disrupting supply chains and leading to higher prices.
