Stephen Dunbar-Johnson, the IHT's commercial director and senior vice president, said he expected the new section, which launches on 21 November, to appeal to B2B, financial and investment advertisers.
To coincide with the launch, the newspaper is planning a promotional and marketing campaign aimed at financial institutions.
Dunbar-Johnson said he expected Marketplace to draw in a significant number of new readers to the newspaper.
He said: "We have been doing a similar thing with Bloomberg in our Asian edition and it's one of the reasons we are the best selling international newspaper in Asia. We hope and expect it to have a similar impact in Europe."
Average circulation for the European edition of the IHT in 2004 was 144,797, with the UK taking 11,765 or 8% of the share.
Mike Oreskes, executive editor of the IHT, said that launching Marketplace was the next logical step for the newspaper. He said: "What we are adding is hardcore financial depth and I think this will add a considerable amount to our current business reports."
The announcement coincides with this week's rollout of the compact version of rival title, the Wall Street Journal Europe.
IHT bosses have ruled out a similar move, pledging to invest in further product enhancements such as the planned launch of a luxury magazine.
