A currency crisis is driving Argentina deeper into a recession. The peso is down more than 50 percent so far this year, competing in a race-to-the-bottom with the Turkish lira as the worst-performing currency in emerging markets. An emergency measure by the central bank, hiking interest rates to 60 percent from 45 percent, didn’t stop the peso’s plunge. Nor has selling reserves. Analysts say the lack of a clear, consistent strategy in South America’s second-largest nation is causing investors and the public to lose faith in the government of President Mauricio Macri.
