Italian lenders are studying countermoves to Intesa Sanpaolo's surprise takeover of UBI Banca earlier this year, bankers say. Italy's Treasury is looking for a buyer for bailed-out lender Monte dei Paschi di Siena and UniCredit is widely seen as a potential candidate.

"We have a very clear message, which is no M&A, and we use our excess capital to fund capital re-distribution," Mustier told a banking conference organised by S&P Global.

Mustier said it was "a matter of when not if" before the European Central Bank allowed banks to resume paying dividends or carrying out buybacks. He added the boost to earnings per share from such actions was larger than what could be obtained through mergers.
