The Mexican peso/US dollar currency cross is possibly the most sensitive markets gauge of how likely a Donald Trump victory is, as traders worry about whether a Trump President would dismantle trade relations with its southern neighbour.
The US dollar slid nearly 2 per cent to 19.51 pesos as presidential hopefuls Clinton and Trump clashed over the economy, cyber security, trade and race in New York.
“This is the FX market’s current weapon of choice, such is the level of concern that were Trump to win, he would unleash a trade war with Mexico,” says NAB global co-head of currency strategy Ray Attrill.
It’s a sharp turnaround as investors have punished the peso in recent weeks. The greenback had climbed nearly 10 per cent since early September as polls started tightening, extending a rout for the Mexican currency which has lost nearly a third of its value over the past two years. Net short positions on the peso jumped 37 per cent in the week ending September 20 and were at the highest in more than 20 years of data.
The Australian dollar also rose 0.6 per cent to US76.63¢ during the debate.
The Japanese yen, a safe haven currency for foreign exchange traders, weakened as relief swept through financial markets. Japan’s currency had climbed earlier as a Bloomberg Politics poll showed the candidates deadlocked before the debate.
The yen dropped 0.4 per cent to 100.74 per dollar during the 90-minute debate. It had touched 100.09, the strongest since August 26 before the start of the debate.
“The market has been ignoring the US election as a risk just as it had with Brexit,” said Peter Rosenstreich, head of
market strategy of Swissquote Bank. “But the combination of new elections polls and uncertainty of tonight’s debate has put the market on edge.”
Gold as a safe haven asset slid 0.4 per cent during the debate.
“On balance, the markets perceive that the first debate went to Mrs Clinton, hence USD under a bit of pressure,” said Annette Beacher chief Asia-Pacific macro strategist at TD Securities. “Risk assets are a little firmer after a soft overnight session.”
