Argentina’s central bank is in talks with private lenders about adding a put option to its local bonds that would compel the monetary authority to buy back the notes if prices fall too far. The central bank would be the counterparty for the option and the contract would have a 2% annual cost to the banks that purchase them. On Monday, the economy ministry announced it would sell local notes and bonds as it seeks to roll over 9bln pesos ($71mln) coming due. The government will have to face a much larger maturity of about 500bln pesos at the end of this month.
