ZURICH (Reuters) - On Jan. 19, Credit Suisse (CSGN.S) Chief Executive Tidjane Thiam contacted the head of the Swiss bank's markets business asking for more details about the fourth-quarter results at the trading division, according to materials seen by Reuters.

Two-and-a-half months and nearly $1 billion in write-downs later, investors, analysts and former board members are questioning why Thiam and his finance chief, David Mathers, were caught out by the scale of the division's illiquid trades -- positions that are not easy to sell out of.

The write-downs have compounded for Credit Suisse what has already been a tough start to 2016 for all investment banks, with its share price down around 38 percent so far this year, one of the biggest slides of all large European lenders.

In January, Thiam, by then just over six months into his job as CEO of Switzerland's second-biggest bank, wondered whether Credit Suisse had gone too big on some trades and addressed the issue with another top executive.

"I wonder about the absolute size of our inventory in a number of activities," he told Global Markets head Tim O'Hara on Jan. 25, according to the materials shown to Reuters on condition that no further details would be disclosed.

"You and I need to discuss case by case the appropriate inventory levels," Thiam said.

Thiam has said he and other senior bank officials were unaware of the size of the positions behind the write-downs but that no trading limits had been breached or trades concealed.

In response to Reuters questions about the bank's risk management and the exchange between Thiam and O'Hara, a Credit Suisse spokesman reiterated those comments.

"He only learned of the extent of the positions in January and took steps to address the situation," the spokesman said.

Thiam and O'Hara declined further comment on Monday.

On Feb. 4 the markets division reported an adjusted pre-tax loss of 658 million Swiss francs ($686.35 million) for the quarter, in which Credit Suisse racked up $633 million in write-downs on illiquid trades. A further $346 million in write-downs followed in the first quarter as of March 11, the bank disclosed on March 23.

Now Thiam faces questions about the bank's risk controls and oversight by senior management of part of its markets business.

"Does it raise concerns? Yes it does," said Andreas Vendetti, an analyst at Swiss private bank Vontobel who rates Credit Suisse's stock "hold".

Some people familiar with the Zurich-based bank's operations expressed surprise and scepticism that top management could be unaware of such important details.
