One-month risk reversal on EUR/USD, a measure of the spread between call and put prices, prints the highest level since December 08 for Wednesday per data source Reuters. 

A call option gives the holder the right but not obligation to buy the underlying asset at a predetermined price on or before a specific date. A put option represents a right to sell. 

That being said, the daily difference between them rose to +0.038 at the latest, per Reuters.

It’s worth noting that the options market’s optimism could be witnessed in the EUR/USD price moves that rose the most in two weeks. However, the latest challenges to the risk appetite seem to test the pair buyers ahead of the key US data.
