The Turkish Lira crashed 20% within a few days and the fall was accelerated by a speech by Turkish President Erdogan and a Tweet from US President Donald Trump... "There are various campaigns being carried out. Don't heed them," Erdogan said Thursday "Don't forget, if they have their dollars, we have our people, our God. We are working hard. Look at what we were 16 years ago and look at us now," Erdogan told supporters. A few moment later, Donald Trump tweeted.
