Trumpcrash
The surprise results (well, surprising to journalists, anyway) of the 2016 presidential election of Donald Trump caused a temporary upheaval in the worldwide financial markets that lasted... hours, maybe minutes.
Known as the Trumpcrash, the Dow Jones futures markets plunged almost 900 points, but recovered the next day when he made his acceptance speech and dialed down some of the rhetoric from the campaign. The international markets were not so fortunate with Asian markets falling because of their distate for his tariff policy which focused on trying to have the frictions that those countries lay upon the U.S. to be equally shared in the other direction.
To date, trade restrictions have highly favored other nations over the U.S. so um it's probably not surprising that Asian markets wanted their parties to continue on the backs of U.S. workers. Additionally, the Mexican peso dropped to a record low against the U.S. dollar with talk of building a wall and reducing free trade with them. However Wall St. did respond well to his promise of corporate tax cuts, and the stock markets made prodigious gains in the years after the election day.
