It has to be said, that 2017 was a very good year for the Polish Zloty. One reason is the strong global risk sentiment but strong Polish economic numbers and the change in government has also played a role. Regardless of how you feel about the Emerging-market currencies and CHF/PLN in particular, one could argue that they are getting close to a bounce. It may not be the ultimate low, but I think value players will be looking soon at these currencies. Disclaimer: I have no CHF/PLN position, but may initiate one in the coming days.
