The CHF is the strongest
As London traders exit for the day, the list of the strongest and weakest has seen the CHF increase in value since the NY open. The USD has taken over as the weakest currency of the majors.
Above is the early NY opening rank. Note the spread between the cumulative gains of the strongest and the cumulative losses of the weakest. There was not a lot separating the strong from the weak.
Below is the current ranking. The CHF has moved higher and the USD has gotten weaker, and surpassed the GBP as the weakest.
