Tidjane Thiam, chief executive of the Swiss-based financial services company, said his position on the UK’s divorce from the EU had not changed since last summer.
The lender has a large operation in Luxembourg and last year opened a presence in Dublin, which it has been looking to expand.
Speaking on Bloomberg, Mr Thiam appeared unconcerned over financial uncertainty in the bloc following Brexit and ahead of national elections in France, the Netherlands and Germany.
Asked when he would have a Brexit ‘plan’ and how much he thought the bank's UK business would be affected, Mr Thiam said: “On Brexit our position has always been that we’re flexible.
Tidjane Thiam said the bank could manage different scenarios
It leaves us in a relatively comfortable position of having flexibility
“We have operations in the EU, we have a big platform in Luxembourg that we’ve used for many years and we have opened in January 2016 a platform in Dublin, which is very helpful to us.
“So it leaves us in a relatively comfortable position of having flexibility and being able to manage in different scenarios.”
Credit Suisse Group is reportedly exploring its options for expanding in Dublin, as the UK moves closer to exiting the European Union.
Ireland aims to present itself as a top destination for financial firms based in Britain that wish to keep “passporting” rights, which allows them to do business within the EU.
But it has been announced that Mr Thiam is preparing to cut thousands more job at the company after it recorded a worse-than-expected £1.9bn quarterly loss.
It is reported the firm may slash between 5,500 and 6,500 staff this year on top of the 7,250 employees in 2016. Many of last year’s job losses came from investment bankers but the lender has not said where this year’s cuts would fall.
Last year, the CEO said Brexit had not changed the bank’s plans and it was business as usual.

He told CNBC: "Brexit has no immediate impact, London is a big financial centre, we have a lot of jobs in London that are going to continue operating in London and as things are clarified we will adapt our strategy."
