According to a source close to the pitch process, around six firms with a global presence are vying to handle the brief.
It is understood that the newly created brief does not include the US.
The source said that NASD is looking to raise awareness of its services outside the US, including its role advising governments on regulatory affairs.
It also operates a securities dispute resolution service.
The brief is mainly media relations focused with the key target group being government finance ministers.
It involves launching NASD and raising awareness of the work it does as government adviser, helping to set up legal frameworks. The pitch is being co-ordinated by its London office.
NASD is best known as the former owner of Nasdaq, which it sold off in 2000 to concentrate on its regulatory and advisory work.
It operates as a private, not-for-profit organisation. In the US, around 5,200 brokerage firms, more than 95,000 brand offices and around 661,000 registered security representatives come under its jurisdiction.
