"In comparison to previous months the cooling trend gathered some momentum in December. The prospects for the Swiss economy are noticeably bleaker in the new year," the KOF said in a statement.
In a separate report, the UBS bank said that Switzerland's consumption indicator strengthened further in December reflecting increases in hotel stays, despite no improvement in the retail industry. A gauge of consumption, which includes consumer confidence, consumer spending, tourism, new car sales, and retail activity, climbed to 1.34 from 1.23 in November.
