The dollar rose 1 percent on the day versus the Swiss franc on Tuesday, as the Swiss currency came under pressure on a broad upturn in risk sentiment and traders targeted option structures at 1.0600 francs.

Traders said the dollar rose to 1.0604 francs on dealing platform EBS, its highest level in nearly 2 weeks.

A digital option expiry was said to be in play at 1.0600, with some suggesting dollar/Swiss would need to be trading above that level at the 1400 GMT expiry for the option to pay out.
