Credit Suisse declined as much as 6.4% and traded 5.6% lower by 3:13 p.m. in Zurich.
Gottstein is attempting to clean up the bank after it was tied to two companies embroiled in scandals, Luckin Coffee and Wirecard AG. Credit Suisse, which had organized a margin loan for Luckin founder Lu Zhengyao, took a large hit in its Asia business earlier this year, setting aside about $100 million for soured loans that mostly related to three cases, the largest of which was Luckin. The bank also helped sell $1 billion of Wirecard-linked securities last year after questions were raised about the German company’s accounting.
