Toyota Leads Losses After Renesas Fire Stokes Chip Crunch Fears

Japanese automaker shares fell Monday after a fire unexpectedly halted one of chipmaker Renesas Electronics Corp.’s largest plants, exacerbating a growing global shortage of automotive semiconductors.

Renesas slid as much as 5.4%, while customers from Toyota Motor Corp. to Honda Motor Co. and Nissan Motor Co. also fell in early trading. One of the biggest suppliers of car chips, Renesas was forced to halt a Japanese plant Friday after a fire broke out in one of its clean rooms, critical areas designed to keep impurities from contaminating semiconductors.

Toyota said Monday it’s trying to gauge the fallout from that unexpected halt, which could ripple across an industry already struggling to keep assembly lines operating during a severe shortage of chips. The Renesas fire will likely worsen a crunch that stemmed from booming demand for home and work gadgets during the pandemic, estimated earlier this year to cost global automakers about $61 billion in lost sales in 2021.

Chief Executive Officer Hidetoshi Shibata warned the plant could be sidelined for a month and cost the company 17 billion yen ($156 million) in revenue.

“I’m concerned that this will have a very big impact,” Shibata said at a news conference on Sunday, following the fire.

Renesas, which posted 715.7 billion yen in revenue last year, gets about 6.6% of its sales from Toyota, according to Bloomberg’s Supply Chain Analysis. The Japanese automaker also warned that cold weather-induced semiconductor shortages will force it to suspend a factory in the Czech Republic for two weeks. A Toyota representative said it’s investigating the potential impact from the Renesas stoppage but had nothing more to share at this moment.

“This is turning into a negative story,” said Takeshi Miyao, an analyst at independent researcher Carnorama. “Production is shrinking, not increasing, so the balance between supply and demand is only getting worse.”

Shibata had told Bloomberg News earlier in March that shortages could persist into the second half, joining other industry leaders in bracing for a chip crunch to snarl production of cars and gadgets well past the summer.

“This is terrible for the automobile supply chain; they might have to move toward holding more inventory,” Bloomberg Intelligence analyst Masahiro Wakasugi said of the Renesas fire.

Renesas has production facilities at six sites in Japan. The N3 building where the fire broke out is home to 300-millimeter wafer production, which would make it one of the company’s more advanced lines. In 2019, Renesas was the third-largest maker of automotive silicon. Along with Toyota, Renesas counts Japanese personal electronics maker distributor Ryosan Co. among its biggest customers, Bloomberg’s analysis shows. Carmakers including Volkswagen AG are also clients, with Honda Motor Co. and Nissan Motor Co. contributing about 2% of sales apiece.

“Supply will remain tight through the first half of the year,” Shibata said in the interview published March 12. “And the way things look now, the situation will continue into the second half. But it’s anyone’s guess.”
