It is not clear how much foreign currency the government has injected into the market since the first week of September when the rial began to fall.Unlike past nationwide unrest, this time it is clear that protesters want an end to the clerical regime of the Islamic Republic and will not be easily satisfied with minimal concessions, even if the hardliner core of the regime decides to offer an olive branch.However, it is not clear how much discount Tehran is offering Chinese buyers and how much foreign currency it receives despite parallel US banking sanctions.So far, hardliners in charge of the military, the presidency and parliament have shown no willingness to compromise with the populace, but even major concessions may prove to be insufficient to quell the young generation that has tasted success in defying a fearsome suppression machine fore almost 7 weeks.The government is talking about a 20-percent raise for workers in its sprawling state-sector economy, but the rial's steep fall has already eaten away at any benefit for workers who make less than $200 a month."
