According to industry sources, choosing an ad agency has become a high priority.
"They need to figure out what to do with their brand so that puts agency selection toward the top of the priority list, one source said.
The pitch covers the four markets where UOB has as a presence - Singapore, Hong Kong, Thailand and Malaysia.
It is understood those invited to pitch are DDB, McCann-Erickson and one other undisclosed agency.
McCann has handled most of UOB's advertising in recent times, while DDB/Rapp Collins has UOB Asset Management.
Since the merger last September, UOB has become Singapore's largest domestic bank ahead of DBS Bank.
It has been quick to phase out the UOB brand by redecorating branches, revamping ATMs and changing the company's marketing materials.
The consolidation in the banking industry in Singapore was spurred on by government deregulation.
It remains unclear which agency is the main incumbent on the OUB account.
However, FCB handles most OUB below-the-line work.
