MILAN, May 22 (Reuters) - UniCredit studies every possible acquisition target for the bank, Chief Executive Andrea Orcel told the Financial Times in an interview, ruling out interest in Societe Generale.

Citing people with knowledge of its Russia exposure, the newspaper also reported that UniCredit would book provisions for potential losses in its next quarterly results after a court-ordered seizure of some of its assets in Russia.

A St Petersburg arbitration court last week seized 463 million euros ($503 million) in shares and other securities, accounts and property, or 5% of UniCredit's Russian assets, in a case over a gas plant project that was aborted due to Western sanctions.

Ample excess capital that can be deployed for mergers and acquisitions have fuelled speculation about Orcel's M&A moves since the investment banker arrived at UniCredit in 2021.

Orcel has walked away from a deal to buy bailed-out rival Monte dei Paschi di Siena, but he explored possible bids for smaller Italian lender Banco BPM as well as Germany's Commerzbank, sources have previously told Reuters.

"Theoretically, most of the rumours are true inasmuch as, in every single market we look at every possible target," he said.

UniCredit operates in 13 markets, with a large presence in Germany and Austria.

"The interest is there under the right conditions, but we haven't found the right conditions yet, and we have had the discipline to say no."

Orcel welcomed a recent call by French President Emmanuel Macron for European banks to join forces, but ruled out any interest in Societe Generale after Macron said Paris would not oppose a foreign buyer for the French lender.

"It's good to have this...commitment from a major European leader," Orcel said.

But "if the rules...don't change, no one is going to be interested beyond domestic because you can't make synergies," he added.
