Thaksin was reported as telling Swiss newspaper Mittelland Zeitung that he would sue Swiss banks for freezing his accounts and revealing a customer's confidential records.
The newspaper quoted Thaksin in advance extracts from an interview scheduled for publication on September 16.
"Good old bank secrecy is no more. Absolute discretion is a thing of the past," he said.
Jaruvan said the AEC did not even have contacts with those banks.
AEC member Kaewsan Atibhodi said the AEC knew nothing about the matter. If the report was true, the Swiss banks might have moved on their own, he said.
Jacques Lauer, an official of the Swiss Embassy in Bangkok, said Switzerland had no financial crime treaty with Thailand so it would be hard for authorities here to make requests to impound Thaksin's assets domiciled there.
Swiss authorities would also never take action until Thaksin was found guilty with solid evidence, Lauer said.
Thaksin's lawyer Noppadon Pattama said he could not comment on the report because he had been in China and had not communicated with Thaksin for a while.
