The US Treasury has weighed in on the Brexit discussion by stating that a Brexit will have a negative impact on the British, European and world economies. US Treasury Secretary Jacob Lew said this week that the consequences of a Brexit, in terms of the flow of trade and economic relationships, would have far-reaching repercussions which will not be “...good for the European, or the British economy, or the global economy…", adding that "It is clear that when you increase the level of unease, it has an economic consequence."
