(Photo courtesy of Envision AESC Group) Copper, used widely in wire harnesses and motors, is up by half, based on London-traded futures. EVs require two to three times as much copper as is used in gasoline cars.
EV inputs are not the only materials going up in price. Rhodium, used in catalytic converters to scrub tailpipe exhaust, is now 30 times as expensive as five years ago. Steel for autos has also become costlier owing to higher iron ore prices.
All of this puts a dent in automakers' earnings. Toyota, Japan's top automaker, expects a 440 billion yen hit to operating profit, or 18% of its forecast. Honda sees a 250 billion yen impact, or 38% of its operating profit guidance.
Nissan Motor, Subaru Corp., Mazda Motor and Mitsubishi Motors face blows ranging from 37.4 billion yen to 100 billion yen.
This pressure on automakers' earnings is not confined to Japan. General Motors expects an annual cost increase of several billion dollars linked to higher materials prices. The average materials cost for a gasoline auto made in the U.S. came to $3,600 in May, double the year-earlier level, according to consulting firm AlixPartners.
With automakers planning to ramp up output of electrics, the EV market is expected to reach 23 million vehicles in 2030, 10 times its size in 2020. Analysts say this pace of growth could keep prices of lithium and other battery materials elevated.
Materials inflation bites beyond the auto industry. Japan's Daikin Industries, one of the world's top air conditioner makers, forecasts a 53.5 billion yen cost increase this fiscal year on the back of higher copper prices. Panasonic sees materials costs shaving 50 billion yen from its profit.
Coping with this pressure will test companies' efforts both in research and development and on the supply chain front. Nissan, Tesla and others are developing powerful batteries that do not require cobalt. The Toyota group and Volkswagen are each moving to lock in rights to lithium mine output. Panasonic has joined a project led by U.S. oil services company Schlumberger that seeks to extract lithium from underground salt water in a fraction of the time.
Passing along higher costs to car buyers is a harder option, industry voices say.
"It's difficult to raise [vehicle] prices" while remaining competitive, said an auto industry executive who asked not to be named.
