ZURICH, Oct 22 (Reuters) - Swiss exports fell in September on weak demand across all regions and sectors, highlighting the bumpy road out of recession for the Swiss economy. Swiss exports fell 2.3 percent on the month when adjusted for price effects and seasonal swings, the Federal Customs Office said on Thursday.
Exports were down 16 percent in real terms when compared to last year. Imports were 10 percent lower. The nominal trade surplus widened to 1.9 billion Swiss francs in September, up from 1.7 billion francs in August.
Signs have been mounting recently the Swiss economy is recovering already from the worst recession in over three decades.
But the Swiss National Bank has cautioned that the sustainability of the global recovery was still uncertain, sticking to its ultra-loose policy, including bond purchases, currency interventions and interest rates close to zero. (Reporting by Sven Egenter; editing by Chris Pizzey)
