the problem is BRICS trading without a reserve currency. US dollar purchases down 8% last year (how much this year?).
Some serious cope about this from boomer burgers on /pol/ kvetching that BRICS isn't a threat because none of their currencies are reliable / trusted enough to assume reserve currency status.
They don't seem to realize, reserve currency isn't needed when you have commodities to barter, not only that, seem to be doing it intentional.
Shifting reserve currency is how how zog is able to shift from host to host, Dutch-> UK -> US etc.

The beauty of bartering commodities instead of using a reserve currency is, no medium / middlemen required, ergo parasites need not apply.
