Shock Therapy Awaits Argentina as Macri Breaks the Kirchners’ Grip by Geoffrey Smith @FortuneMagazine November 23, 2015, 6:26 AM EST E-mail Tweet Facebook Linkedin Share icons Buenos Aires mayor Mauricio Macri swept to power in Argentina’s presidential election run-off Sunday, heralding a new departure for South America’s second-largest economy. Macri defeated Daniel Scioli, the heir-apparent to left-leaning President Cristina Fernandez de Kirchner, who succeeded her husband Nestor as President eight years ago. Macri has promised to bring Argentine policy back into the western mainstream after a decade of increasingly erratic rule under the Kirchners, in which the country defaulted twice on its international debts. Argentina, one of the world’s largest agricultural exporters, had ridden the Chinese-fueled commodity ‘supercycle’ but has struggled since that boom turned to bust. Inflation has soared to around 25% as the government has increased spending, notably on subsidising energy and public transport, in an effort to sustain living standards. Subsidies now cost over 5% of GDP, according to Luiz Kessler at Oxford Economics. The local stock market has already risen 25% since the first round of voting in October, when it first began to sense that Macri could win. The Buenos Aires mayor had got a better-than-expected 34% in the first round of voting, only just behind the 37% polled by Scioli. Macri built on his momentum to take 51.4% of votes in the run-off to Scioli’s 48.6%. OE’s Kessler argues that, while both candidates recognized the need for change after 12 years of ‘Kirchnerism’, the main difference between the two candidates is the speed at which they intend to push through reforms, starting with the abolition of the country’s dual exchange rate regime that will probably lead to a sharp fall in the peso in the short term. While a dollar buys 9.64 pesos at the official rate, its black market value is over 15. Macri has promised to end capital controls on his first day in office. If Macri implements the ‘shock therapy’ that he has promised, the economy could contract by 3% in both of the next two years before starting to recover in 2018, Kessler said in a note to clients.
