Argentine peso futures have weakened sharply in recent days as traders place tentative bets on a faster depreciation of the embattled currency amid uncertainty over the exchange rate regime ahead of a deal with the International Monetary Fund. The April peso future contract has weakened to around 1,180 per dollar from 1,125 on April 9 when the IMF announced that it had reached a staff-level agreement with Argentina over a new $20 billion loan program to help bolster depleted reserves. That's seen traders playing a guessing game on what that might mean for the currency, which is currently held in check by strict capital controls and a so-called crawling peg, which allows it to depreciate at 1% each month currently.
