The data on Swiss trade in precious metals for January 2014 has been broken down by country for the first time in 30 years, report swissinfo.ch and vaterland.li. It shows that Switzerland imports most of its gold, silver and precious coins from the UK, while its main export markets are in Asia. Total exports were over 5.3 billion euros in January, while imports were worth almost 6 billion euros.
The press release by the Swiss Federal Customs Administration has the breakdown by country.

No explanation is given in the press release for this sudden growth since 2005. Given that Switzerland is a commodities hub and not a producer there was most likely a change in trade regulations or taxation around this time.
