The latest prediction of an economic slowdown in 2012 comes from Thomas Jordan, the interim head of the Swiss National Bank.

Speaking at the Swiss American Chamber of Commerce in Geneva today, Jordan warned that economic certainty abounds.

He said the strength of the franc as well as the sluggish global economy would weigh on Swiss growth, which he puts at just 0.5 percent for the year.

But that’s assuming there are no major shocks.

Jordan warned that the debt crisis in Europe would have the most drastic influence on the Swiss economy.

He also used the opportunity to reiterate the bank’s support for the 1.20 franc-to-euro floor, saying that the bank would continue to defend it at any cost.
