Korean battery stocks plunged Friday on reports that President-elect Donald Trump's transition team plans to scrap the $7,500 tax credit for EV purchases as part of broader tax legislation.

Trump campaigned on ending the consumer tax credit, a key part of President Joe Biden's Inflation Reduction Act (IRA). And the transition team said Trump would keep his pledges, according to earlier news reports.

The news added to woes of local EV battery stocks already struggling with the EV "chasm," which occurs before the widespread adoption of all-electric vehicles.

LG Energy Solution, the country's leading car battery maker, slumped 12.09 percent to 371,000 won, No. 2 maker Samsung SDI retreated 6.81 percent to 246,500 won, and SK Innovation, which owns an 89.52 percent stake in No. 3 firm SK On, shed 6.43 percent to 96,100 won.

The broader Korea Composite Stock Price Index, or KOSPI, only slipped 0.08 percent.

Battery materials shares also suffered declines.

POSCO Future M plunged 9.5 percent to 167,600 won, while EcoPro Materials plummeted 15.06 percent to 89,700 won, and L&F dipped 11.04 percent to 97,500 won.

The IRA, signed into law by the Biden government in August 2022, offers up to $7,500 in tax credits to each buyer of a new EV that was assembled in North America and made with minerals mined and processed in the U.S. or countries and regions that have free trade agreements with Washington. (Yonhap)
