Capital markets do not tolerate uncertainty well. And for good reason: When the future is less clear, risk rises. Risk is defined as the probability of the unexpected occurring. When expectations are blurred, as is the current case with the tax reform legislations winding its way through the corridors of political power in the US, the probability that an unexpected outcome will occur rises, hence the risk. The likelihood that the bill will falter altogether or that it will arrive with less than clear benefits for business and industry is causing the US Dollar to become weaker relative to the Euro and the Japanese Yen.
