The public sector's finances are deteriorating by 43 billion kronor this year. The deficit is estimated to land at 80 billion kronor, according to a new forecast from the National Financial Management Authority (ESV).
As a result, the state's finances will fall short of the Riksdag's target for this year.
The low-growth economy means that tax revenues are increasing slowly.
"At the same time, expenditure in the state is increasing significantly due to the previously high inflation, increased defence expenditure, and other measures in the budget proposal for 2024," writes ESV in a press release.
The municipal sector is also responsible for a large part of the total deficit.
Next year, the finances will rapidly improve again, and the deficit will shrink to eleven billion kronor.
The national debt remains low and is relatively stable as a percentage of Sweden's GDP, rising slightly this year and falling again in 2025, according to ESV's forecast.
