Credit Suisse has asked investors for about $2 billion because the chief executive is trying to rebuild his finances after suffering “unacceptable” losses.

The Swiss banking giant, one of the industry’s most respected names, has gone bankrupt.

On Thursday, Swiss regulators announced that they were expanding their investigation into Credit Suisse’s activities.

These are related to transactions with two companies called Archegos and Greensil.

Credit Suisse has lost billions of dollars since the U.S. hedge fund Archegos folded.

The bank is also a donor to the failed financial institution Greensil, which has made headlines for funding Liberty Steel in the UK and lobbying former Prime Minister David Cameron.

On Thursday, Credit Suisse posted losses of 757 million Swiss francs ($ 827 million) for the first three months of the year, previously warning that losses could reach SFr 900m.
