By David F. Lafferty (Natixis) | Over the last few months, we have written, spoken, and tweeted incessantly about the coming headwinds to both the global economy and the capital markets. In July we noted that despite the current macroeconomic momentum, there are many factors that are likely to hamper growth by the time we get to late 2019 or 2020. These include tighter monetary policy that will actually begin to pinch growth, fading tax-cut and fiscal stimulus (especially if the Democrats take the US House of Representatives in the midterm elections), continued trade and export headwinds, a Brexit supply-shock to the UK and EU, and so on.
