The only reliable guide to the dollar’s value in the wake of Donald Trump’s electoral victory is the wisdom of legendary investor Bernard Baruch about the stock market: it will fluctuate. If the prospects for the US economy have never been so uncertain, then the prospects for the dollar similarly have never been so uncertain.

Still, we can attempt to make sense of this scenario from three angles. A first is from the vantage point of US fiscal and monetary policies. One thing we know is that a more expansionary fiscal policy is coming. It may take the form of tax cuts for the wealthy and tax credits for investors; or it may be a more balanced programme, including a significant rise in infrastructure spending.

Either way, growth and inflation are likely to accelerate, and the US Federal Reserve will respond by raising interest rates sooner and faster. We know from the Reagan era that a mix of loose fiscal and tight monetary policies makes for a strong dollar. No surprise, then, that investors are bidding up the greenback.
