Mr Brown said that it was vital to secure a 'low inflation economy' that has the 'flexibility to make the right decisions'.
Three-year deals would help control inflation and make it easier for workers to budget for the long term, he said.
Mr Brown added: 'There is no point in a big salary rise that is wiped out by a big inflation rise.'
Chancellor Alistair Darling said three-year deals would also help government departments manage their spending plans.
Mr Brown was not specific about whether GPs were included in the idea.
But it appears unlikely that this thinking will influence the current contract changes to be voted on by GPs before April.
