The Swiss Federal Statistics Office released its consumer inflation data on Friday. Switzerland's consumer price index fell 0.4% in December, missing expectations for a 0.3% fall, after a 0.1% decrease in November.

The decline was partly driven by lower prices for petroleum and food products.

On a yearly basis, Switzerland's consumer price index rose to -1.3% in December from -1.4% in November, missing forecasts for a 1.2% drop.
