Investment bank loss mars Thiam's final act at Credit Suisse

By Brenna Hughes Neghaiwi

ZURICH (Reuters) - Credit Suisse posted its highest annual profit in nearly a decade on Thursday, but volatile earnings at its investment bank and trading divisions muted outgoing Chief Executive Tidjane Thiam's swan song.

The 57-year-old Franco-Ivorian native will leave the Swiss bank on Friday following a spying scandal which clouded the final overview of the turnaround he has led since joining Credit Suisse in 2015.

Thiam said Switzerland's second-biggest bank would continue to benefit from the bet it made on global wealth nearly four-and-a-half years ago, shortly after his arrival.

"It's not my job description to make myself indispensable, but to build something that lasts," an emotional Thiam told journalists and executives gathered at the lender's Zurich headquarters.

He later referenced public tensions that had emerged over spying in recent months.

"There are differences, within Switzerland, in how people feel about me. That's life," he said. "All I can say in conscience is every second, I've done the best I could."

Thiam will be replaced by company veteran Thomas Gottstein, a long-time dealmaker promoted under the outgoing CEO to run the lender's newly created domestic unit in 2015.

Gottstein on Thursday confirmed his commitment to the strategy initiated by Thiam, describing his predecessor as a "personal friend".

At 3.419 billion Swiss francs ($3.5 billion), the bank's 2019 profit was the best since 2010.

However, a steeper-than-expected loss in its investment banking business and a ramp-up in pressure from climate activists, at odds over Credit Suisse's fossil fuel financing, underscore the challenges which remain for Gottstein.

The 55-year-old, in his first public appearance as designated CEO on Thursday, said that after years of cost cuts the bank was now poised to start reinvesting into its businesses.

"Going forward, I see many attractive opportunities to grow... and this growth should for the first time in a long time also be based on the reinvestment of surplus capital," he told journalists in Zurich.

Following his appearance, activists gathered around the lender's Paradeplatz headquarters to demand its divestment from fossil fuels, likening it to a sinking ship.

A CLEAR CONSCIENCE

Thiam spent much of his time at Credit Suisse trying to put the lender on a more stable footing, slashing costs and exiting riskier and more capital-intensive investment banking activities.

But his legacy will be defined by the spying controversy which saw Credit Suisse, one of the highest-profile names in European banking, admit to snooping on two former executives.
