The Swiss government said Wednesday it suffered its first federal budget deficit in nearly a decade last year following a surprise nine percent drop in tax revenue.
The deficit of 124 million Swiss francs (118.5 million euros or $133.8 million) was the first since 2005, and was also a surprise as Bern had forecast for 2014 a budget surplus of 121 million francs.
Swiss Finance Minister Eveline Widmer-Schlumpf said "we will investigate" the 2.4 billion franc shortfall in revenues.
The deficit would have been higher had Bern not cut spending by 2.1 billion francs.
In 2013, Switzerland recorded a federal budget surplus of 1.3 billion Swiss francs.
The revenue shortfall does not augur well for Switzerland as its economic growth is expected to slow due to the sharp rise in the value of the franc after the central bank abandoned last month its efforts to keep the value of the currency down.
Swiss banking giant UBS believes the country's economic growth will slow from an estimated 1.9 percent in 2014 to 0.5 percent this year.
