ZURICH (Reuters) - Windfall revenue and falling debt service costs as a result of negative interest rates helped the Swiss federal budget swing to an underlying surplus of 752 million Swiss francs (£597 million) in 2016, the government said on Thursday.
But it forecast structural deficits of 1.0 billion francs in 2018, 1.1 billion in 2019 and 0.5 billion in 2020, announcing spending cuts to ensure it meets limits on fresh borrowing.
Gross debt fell to 98.8 billion francs at the end of last year from 103.8 billion, it said.
