The US Dollar plummeted against the Yen and Euro while the Mexican Peso also fell to a record low with gold gaining more than five percent.
The United States Dollar and stock markets around tumbled on Wednesday as US Republican nominee Donald Trump looked on course to win the race for the White House.
Investors' initial confidence that Democratic candidate Hillary Clinton would win the US election was wiped out as results from key states of Ohio, North Carolina and Florida showed Trump in a clear lead.
Clinton is considered by many investors to be a safer bet than Trump, who is seen as a loose cannon with policies.
Many fear the firebrand tycoon could wreck the world's number-one economy.
The Dollar plummeted against the Yen and Euro while the Mexican Peso also fell to a record low with gold gaining more than five percent.
"It's been a bloodbath in the markets over the last few hours with the Mexican Peso suffering particularly badly as Trump edges ever closer to the White House," said Craig Erlam, senior market analyst at Oanda.
