Sweden’s September 13 parliamentary election is the dominant factor shaping the market, with recent polling consistently showing the centre-left opposition bloc led by Social Democrat Magdalena Andersson ahead of Prime Minister Ulf Kristersson’s Tidö parties by margins of roughly four to eight points. Preferred prime minister surveys have placed Andersson well ahead of Kristersson for months, reflecting voter assessments of the two main contenders. The campaign has centred on cost of living, gang crime, immigration, security and energy, with the right-wing bloc narrowing the gap in the final weeks but still trailing. Andersson’s position as the clear frontrunner for forming the next government rests on these bloc-level trends and the expectation that her party will anchor any incoming coalition.
