Geopolitical events invariably cast a shadow over markets, but it is relatively rare for them to manifest into something that affects the economic cycle. Events that alter the secular trend are even more exceptional but this is not to say that they don't happen. Thatcher's deregulation drive of the 1980s and FDR's 'New Deal' are examples and we suspect that Trumponomics may be another. Labelling Trump's policies as Trumponomics is unhelpful since it hints of an underpinning philosophy, which is entirely absent. Political direction rests with a demagogue.

For decades, economies and markets have quietly benefited from freer movement of goods, capital and labour. This is a trend that has not only been halted but sent into reverse. The direct impact of $20bn of tariff costs on a $20tr economy will be trivial but adds unwelcome grit to the running of the system. It will be interesting to observe voters' reaction as the repercussions are felt. Already, mid-Western soybean growers are grumbling as soon might the blue collar shoppers of Walmart where 70-80% of goods are sourced from China.
