The Swiss National Bank announced today that it was dropping its three year-long peg to the euro. The franc soared on the news gaining as much as 30% against the euro and as much as 25% against the dollar before settling in with about a 15% gain against the USD. The revaluation was a punishing blow to Swiss exporters. The Swiss stock market is down about 8.5% on the news, but in USD terms it is up better than 5%.
