Following in the wake of Greece's Syriza, another far-left party has taken a polling lead in Europe. This time, it is Spain's Podemos, a party founded in March this year, with a distinct and radical platform that could overturn Europe's political and economic course. The party has surged in recent months: it gained 8% of the vote in European parliament elections held this May, and is beating every other party in polls. In the latest set, 27.7% of Spaniards said they would vote for Podemos, beating both the established social democrat party and the governing conservatives. BNP Paribas analyst Victor Echerevarria outlined the party's platform: The rise of Podemos changes the political landscape in Spain: Its party platform includes calls for increased public control of key sectors of the economy (such as energy, or even the pharmaceutical and food sectors), a restructuring of Spain’s public debt and the reversal of the labour reforms of recent years. The issue is not just for Spain. Nationalisation and a massive loosening of fiscal spending are subject to stringent EU rules that the party clearly does not care for: if Podemos got into government and tried to implement their platform, it would provoke outrage in the European establishment and could trigger copycat moves in other countries. Even if it cannot form part of a government, a strong Podemos result at the next election would make forming a stable government in Spain far more difficult. Nicholas Spiro at Sprio Sovereign Strategy says that markets have fundamentally misjudged Spain, and that they could get a shock: One of the reasons why markets have taken a more sanguine view of Spain is that the country's political system always seemed more stable - particularly vis-à-vis Italy... This perception was always a superficial one and is now positively flawed. Political risk in Spain has been rising sharply of late. While investors have focused on the standoff between Barcelona and Madrid, they should be paying more attention to the surge in support for Podemos... Markets would be well advised to reassess their views of Spain which, we believe, have been far too rosy.Join the conversation about this story »
