Wall Street is shorting Donald Trump’s run for the White House — or at least Citigroup is.

The Republican presidential nominee “could trigger a US and global slowdown” if he’s elected, Citigroup predicted Thursday — and said he has a better shot at winning than polls are showing.

If the 70-year-old self-proclaimed billionaire is elected, the global GDP would fall by 0.7 to 0.8 percentage point, said the bank’s research note, which was primarily written by Willem Buiter.

“[A] Trump victory in particular could prolong and perhaps exacerbate policy uncertainty and deliver a shock (though perhaps short-lived) to financial markets,” the report from Citi, led by Chief Executive Michael Corbat, added.

The note gives Trump’s Democratic rival, Hillary Clinton, a 65 percent chance of winning the US presidency, which is lower than the 83.5 percent odds that Nate Silver’s FiveThirtyEight polling site has.

Silver has accurately predicted the last two presidential elections.
