Traders note heavy sales of Swiss from a US investment bank helping give the greenback a boost this morning. EUR/USD has fallen through 1.42 and USD/CHF has rallied as high as 1.0740. The aggressive nature of the move may have spooked the market into fearing intervention, initially.
Earlier today, China was rumored nibbling in USD/CHF, so that too may have been a factor behind the jumpy nature of the market.
