Events in 2021 will be the consequence of a developing hyperinflation of the dollar. Foreign holders of dollars and dollar assets - currently totalling $27.7 trillion - are sure to increase the pace of reducing their exposure. This is a primal threat to the Fed's policy of using QE to continually inflate assets in the name of promoting a wealth effect and continuing to finance a rapidly increasing federal government deficit by suppressing interest rates.
Bubbles will then pop, leaving establishment investors exposed to a combined collapse of fiat currencies, bonds and equity markets, which could turn out to be very rapid. The question remaining is what will replace collapsing fiat currencies: limited issue distributed ledger cryptos, such as bitcoin, or precious metals, such as gold?
