It really depends what Trump will be able to do.
- If he starts a trade war with China, then immediately our biggest and second biggest export market would be in trouble. And that will mean the dollar probably fall to round more realistically 50c/$1.
- If he starts a war with Iran (aka by proxy with Russia), and/or Korea (aka by proxy with China), would mean that Australia will have to put trillions in as well,as part of the coalition of the 'willing". This would blow a massive hole in our budget, increasing our foreign debt (towards various US banks)
- If he is able to do both or part of the above, plus he is able to build a mexican border wall, plus give tax breaks to big companies - like the ones he owned - then, I think.... with the current debt situation in USA, this would cause hyper inflation (reduction of cheap imports), debt crisis, and possibly another recession in USA.
Perhaps, starting hoarding up long life milks, canned food, and gold bars.
