US Treasury Secretary John Snow has said he would not rule out the idea of Bono making the shortlist of potential candidates to head the World Bank.
However, an American is expected to get the job.
The U2 frontman, who has campaigned for international debt relief for poor nations, was nominated to replace the outgoing President, James Wolfensohn, by the Los Angeles Times newspaper.
Mr Snow said he admired Bono for his good work in the economic world.
