We are only 1 or 2 years away from another full-blown global competition for currency devaluation.
The next crisis will NOT be like 2008. In 2008 we began the crisis with the US Dollar Index (DXY) at an all-time record low and the crisis caused a flood into the dollar. Where we are now is much more similar to 2000: High dollar, high stock market, quiet commodities market, incoming easy money policies.
Additionally, the Fed is acting very preemptively. They will not wait until recession is blatant before they take action (like in 2008), they're already doing QE4, which means if the economy turns lower even more ---> they will launch an official and permanent asset purchasing program in order to keep rates low.
We are at the beginning of the end game now: Which is a global race to devalue the currency in order to keep asset prices up and to enable insolvent governments to continue to print and borrow. The global banking system will soon need massive central bank interventions, bigger than anything we've seen before. Look for a new all-time low in the DXY below 70 to be set before the mid-2020s.
