Argentinian president Mr Eduardo Duhalde is considering returning to a fixed exchange rate to help halt a slide in the value of the peso.
The currency has lost nearly 70 per cent of its value since January and trades at more than three pesos to the US dollar.
Mr Duhalde abandoned Argentina's 11-year one-to-one peg with the dollar only days after taking office in January. He said the inflated strength of the peso was at the root of the country's financial problems.
Officials have suggested that a new fixed exchange rate could be set at 3.5 pesos to the dollar.
Mr Duhalde is also working to find a new economy minister following Tuesday's resignation of Mr Jorge Remes Lenicov.
The new economy minister will face the task of trying to help Argentina restore confidence among international investors following a default on the country's huge debt earlier this year.
The International Monetary Fund is also demanding deep spending cuts as a pre-condition for more aid.
