The USD/CHF pair struggles to gain ground near 0.8830 after retreating from nearly the 0.8900 mark during the early European trading hours on Monday. The downtick of the pair is backed by the weaker US Dollar (USD) and lower US Treasury bond yields. Market players await the Swiss February Consumer Price Index (CPI) for fresh impetus, which is expected to ease from 1.3% in January to 1.1% in February.
