The Argentine crisis has demonstrated that unilateral currency pegs imply the risk of serious misalignments with other trading partners and subsequent realignments. The standard basket peg is not a solution because of its limited transparency and credibility. We therefore discuss a proposal to create dual currency boards that could be a workable solution for the Mercosur countries
