ZURICH, Jan 31 (Reuters) - Swiss wealth manager Julius Baer is discussing replacing one or more members of its senior leadership team including CEO Philipp Rickenbacher, Bloomberg News reported on Wednesday, citing people familiar with the matter.

The company declined to comment. Rickenbacher, who has led the bank since 2019, did not immediately respond to a message sent to his mobile phone.

Julius Baer has been under pressure for months over the company's ties to property and retail group Signa, which is controlled by Austrian magnate Rene Benko and last year declared insolvency.

Analysts have estimated the bank's losses in relation to Signa to be around 400 million Swiss francs, and a Swiss newspaper last week said Julius Baer was set to announce a writeoff of around 400 million Swiss francs ($463 million) when it reports its results on Thursday.

Switzerland's financial regulator, FINMA, launched an investigation into the bank over its risk controls, Bloomberg reported in December.

According to the Bloomberg story published on Wednesday, the Swiss firm is also considering other ways to hold executives accountable and could still decide to keep its current line-up as it assesses how it built up exposure to Signa.

Julius Baer's shares have fallen about 14% since November when it revealed it had a 606 million franc exposure - the largest in its private debt loan book - to a European conglomerate. It has declined to confirm if the client is Signa. (Reporting by Oliver Hirt and Noele Illien in Zurich and Harshita Meenaktshi in Bengaluru; Editing by Shailesh Kuber and Alex Richardson)
