We do not like Purchasing Power or Real Effective Exchange Rate (REER) as measurement for currencies. For us, the trade balance decides if a currency is overvalued. Only the trade balance can express productivity increases, while REER assumes constant productivity in comparison to trade partners. On the other side, a rising trade surplus may also be caused by a higher savings rate while the trade partners decided to spend more. To control the trade balance against this “savings effect”, economists may look at imports. When imports are rising at the same pace as GDP or consumption, then there is no such “savings effect”. The Swiss trade balance in August looks extremely healthy: Swiss exports were up 7.0% against August 2015 (in real terms: + 1.2%) and imports 8.4% (in real terms: + 5.1%).Apparently imports increased because there is more export demand, but not because locals decided to consume more. Exporters could even raise prices, as we see in the difference between nominal and real. The difference between nominal and real reflect the fact that in particular pharmaceuticals and chemical exporters could increase their prices in Swiss Franc.
