Donald Trump's electoral upset has breathed new life into the bet that diverging economic paths will drive the euro toward parity with the dollar for the first time since 2002.

Traders see about a 45% chance the European currency will sink to $1 in the next year, about double the probability assigned a week ago, data compiled by Bloomberg show. The president-elect's pledges to boost spending and cut taxes are fueling speculation that economic growth will accelerate, pushing the Federal Reserve to raise interest rates more quickly. That sentiment sent a gauge of the dollar to the strongest since February on Monday, while the euro fell to about $1.07, touching its lowest since 2015.

For Deutsche Bank, the world's fourth-biggest currency trader, the election results are enough to jolt the euro out of a range it's been stuck in for months and push it below $1 in 2017. Calls for parity crumbled this year as the Fed cut back on the number of expected rate hikes, even as the European Central bank continued to add unprecedented amounts of stimulus. Now Trump's win is rekindling the wager that drove the dollar to back-to-back annual gains in 2014-2015, for its biggest two-year rally since the euro's 1999 debut.
