USD/CHF has moved steadily higher to consolidate near the afternoon US high over the last hour or so
I haven't found out what might be catalyzing the move; the closest I can get is I suspect there may be something in the European/Swiss press ... but I stress, I haven't heard/seen anything.
EUR/CHF has gained in a similar looking pattern, even as EUR/USD has dribbled to session lows.
Gold has seen a bit of a slide today also, not huge though.
