When Britain leaves the European Union, the safe-haven demand for gold prices will heat up, which will strengthen the dollar. The currencies of various countries fluctuated to varying degrees.

Sterling: Short-term decline.

Euro: it fell first and stabilized at 1.05.

Yen: Driven by global risk aversion, the yen will become the target of looting.

Swiss franc: It will rise at first, on the grounds that the referendum is risky in Europe.

Canadian dollar, New Zealand dollar and Australian dollar: The trade exposure to Britain is relatively small, and it remained stable in the first round of Britain's exit from the EU.

Renminbi and rupee: they will depreciate in the short term.
