The election of nationalist Karol Nawrocki as Poland’s new president has cast a shadow over the country’s fiscal outlook, adding uncertainty to the government's already delicate efforts to manage public finances, attract investor confidence, and stay within European Union budgetary norms. Nawrocki's victory, seen as a win for conservative opposition forces, complicates Prime Minister Donald Tusk's pro-European reform drive and could hinder fiscal consolidation.

Poland’s budget is under significant strain, not only from ambitious social spending programs but also due to elevated defense expenditures following Russia's invasion of Ukraine. Tusk, who returned to power in 2023 with a centrist coalition, has struggled to balance his campaign promises with economic prudence. His plans have already faced resistance from former president Andrzej Duda, and with Nawrocki likely to follow a similar path, the president’s veto power could paralyze key legislative and fiscal initiatives.

Analysts warn that Nawrocki's administration may intensify political divisions and disrupt policymaking. Eurasia Group’s Orsolya Raczova predicts increased internal discord, especially among coalition partners. Nawrocki is expected to resist reforms, further burdening the state with spending pressures ahead of the 2027 general election. Credit agencies like S&P Global are cautious but maintaining their ratings for now, stressing that Poland’s economic fundamentals remain vital for long-term assessments.

The market reaction was swift. On Monday, Polish stocks slid from recent highs, underperforming regional peers, and long-term bond prices declined, reflecting investor anxiety. The zloty, previously among the stronger emerging-market currencies this year, could face headwinds. Although the IMF projects stable growth around 3% over the next few years, the European Commission has flagged Poland’s deficit as one of the EU’s worst, expected to exceed 6% of GDP through 2025.

Scope Ratings has expressed concern that political polarization could push Poland towards looser fiscal policies, undermining efforts to reduce the deficit. S&P similarly cautioned that while it isn’t adjusting the country's credit rating immediately, rising political risks could eventually impact fiscal credibility. With bond yields stabilizing near 5.5%, borrowing remains relatively manageable for now, but the long-term sustainability of Poland's fiscal path remains in question.

Tusk faces mounting pressure to fulfill high-cost promises, particularly the pledge to double the income tax exemption, which alone would cost nearly 55 billion zloty. Economic analysts argue that delivering this while maintaining fiscal discipline is increasingly implausible. As Professor Aleks Szczerbiak of the University of Sussex puts it, the government is caught in a dilemma—voter expectations tied to populist pledges clash directly with economic realities. Without a clear roadmap, the administration risks being politically cornered and fiscally hamstrung.
