First Abu Dhabi Bank (FAB), the United Arab Emirates' biggest lender, said on Thursday it was considering a bid for London-listed Standard Chartered but was no longer doing so.
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 shares pared the gains to trade up 6% at 1421 GMT following FAB's statement that it was no longer pursuing a potential deal.
The Abu Dhabi lender said it had been in "the very early stages of evaluating a possible offer" for the emerging markets-focused bank.
