Bloomberg had earlier reported that FAB had been exploring an offer for Standard Chartered as part of a plan aimed at building an emerging markets bank, driving StanChart shares up as much as 20%.
The Abu Dhabi lender said it had been in "the very early stages of evaluating a possible offer" for the emerging markets-focused bank.
Furthermore, the mooted combination of FAB and StanChart would have been subjected to more onerous capital requirements that would burden the resulting lender, a banking source said.
FAB was created via a merger between National Bank of Abu Dhabi and First Gulf Bank in 2016.
The lender sources around half its deposits from the Abu Dhabi government and reported total assets of 1.15 trillion AED ($313.1 billion) as of end-September 2022.
