The cause of Brexit: or prevalence of isolationism around the world

It is a national referendum in United Kingdom that people vote whether they should leave from European Union or remain. The result was leave side's won by 52% to 48%, which cause huge financial turmoil all over the world. For example, in Japan, the Brexit result cause \1,286, around 8% plummet at Nikkei average next day.

  • Why the referendum held in the first place?

I should be pointed out first, UK wasn't very much cooperative to EU from the beginning. They have retained their own currency, pond and they have needed passport to travel to EU territory. So, they were rather easier position to leave from EU. And it seems there was anxiety growing among British people these several years, since immigrant population surged when Poland joined to EU, and they prospect of more influx people from Middle East countries. It seems a decisive factor why most of British people wanted to leave from EU. The decision to hold the referendum was made around 2010, when the whole world was suffering from great recession caused by bankrupt of Leman Bro's. At the time, it seems the referendum was mere a political tool for British PM James Cameron to bargain with other EU nations, so the referendum was declared to be hold by him. However, since those perturbed behavior which the PM show after the referendum, it seemed he miscalculated the outcome.

  • What can be predicted from Brexit

Britain would lose more of its access to EU market, which makes around 50% of its export. And it will damage the reputation that London as one of the most important world's financial center. Also, it may impact to Scotland region, since its liquor export businesses will suffer. So, the Scottish momentum to independent from UK might grow more after Brexit. Furthermore, English language's value might be reduced since other EU countries resign to use English as their common language.
