After reporting outflows in the tens of billions in November, the tide is turning and money is flowing back to Credit Suisse says its CEO.

In November, Credit Suisse reported outflows of around 6 percent of assets under management from October to mid-November, totaling approximately 84 billion francs, but the bleeding has been stanched, CEO Ulrich Koerner.

«The outflows, as we said, have reduced very significantly, and we are seeing money now coming back in different parts of the firm,» Koerner told «CNBC» in an interview at the World Economic Forum in Davos on Wednesday.

Transition Going Well

Last year, Credit Suisse embarked on a new strategic path, led by Koerner and financed by a 4 billion Swiss franc capital increase. The transformation to a new Credit Suisse is going well.

«I think the plan, the strategy resonates very much. We are in full execution swing, so I think we are making really good progress,» Koerner said.

Lehmann and Helfenstein

Koerner's comments follow those made by Chairman Axel Lehmann in early December when he told a London banking conference that outflows had reversed and that very few clients had left the bank.

Just days before Lehmann's comments, the CEO of Credit Suisse's Swiss unit Andre Helfenstein, said that the bank «lost a total of 1 percent of our asset base,» adding that very few clients closed accounts after withdrawing money.

CS First Boston

Koerner also commented on Credit Suisses acquisition of Michael Klein's eponymous advisory firm, reportedly valued in the hundreds of millions of dollars, over which conflict of interest issues was raised, including by finews.com.

The deal will allow shareholders in M. Klein & Co. to obtain stakes in CS First Boston.

Koerner sought to dispel conflict-of-interest notions, saying he has «zero concerns,» according to the interview, calling Klein an «excellent banker.»

«We can deal with a situation like that in the utmost professional way,» Koerner said.

In November, Credit Suisse said it expects a $1.6 billion loss in the fourth quarter. It is scheduled to report results on February 9.
