AMP chief economist Shane Oliver has produced a list of risks to markets in the next year, with a key one focused on the White House. President Donald Trump will be less constrained after the coming midterm elections, he says, with a window next year before the presidential election in 2028 where he could might decide to ramp up foreign adventures including another go at Iran, and maybe Greenland and Cuba. This is particularly so if he loses the House and the Senate in November, Oliver adds. (james.glynn@wsj.com; X @JamesGlynnWSJ)
