• USD/CHF snaps a three-day winning streak to over a one-week high amid modest USD weakness.
• Expectations for another 75 bps Fed rate hike should limit the USD losses and lend some support.
• A positive risk tone could undermine the safe-haven CHF and warrants caution for bearish traders.

The USD/CHF pair comes under some selling pressure on Tuesday and snaps a three-day winning streak to over a one-week high touched the previous day. The pair maintains its offered tone through the early part of the European session and is currently flirting with the daily low, around mid-0.9900s.

The data might influence the USD, which, along with the broader risk sentiment, should provide some impetus.
