The trade balance showed a surplus of CHF 2.82 billion in July. It was CHF 1.77 billion in the previous month.
Exports fell by real 3 percent in July from the previous month, reversing June's 3.8 percent growth due to sluggish growth in key trading partners and the strong franc. Exports to the European Union, Switzerland's biggest trading partner, dropped 3.3 percent. Exports to emerging markets, such as China, climbed 27.7 percent.
Imports rose only 0.1 percent after registering a monthly growth of 1 percent.
