The global foreign exchange market does not rest on Saturday and Sunday, because Arab countries do not rest on Saturday and Sunday, but on Friday. So generally speaking, large foreign exchange transactions on Saturdays and Sundays will be transferred to the foreign exchange trading center in Dubai, which is open from 10 to 16 local time (Beijing time 14: 00 ~ 20: 00). For banks, foreign exchange assets such as traveler's checks will still be accepted on Saturday and Sunday. Therefore, at that time, the great Japanese minister of Tibet, Kiichi Miyazawa, once boasted that "the foreign exchange market is not on holiday", but the suspension of holidays on various platforms is different.
