After Jerome Powell's neutral-to-slightly-dovish-but-mostly-boring speech on Friday morning, investors could be forgiven for suspecting that this year's Fed-sponsored gathering in Jackson Hole might be disappointingly dull (especially with all that's going on in Trump's twitter feed, the escalating trade war and escalating geopolitical unrest).

Then along came former Goldman banker and current (outgoing) BOE governor, Mark Carney, who in his lunchtime address laid out a shocking, radical proposal - perhaps the most stunning thing to ever be unveiled at Jackson Hole - urging to replace the US Dollar with a "Libra-like" reserve currency in a dramatic revamp of the global monetary, financial and economic order.

While it was unclear if Carney was focusing on Libra as the new reserve currency, or simply was hoping to find something against which the dollar could be devalued, the proposal was clearly shocking as it suggests that the central bank quiet acceptance of cryptocurrencies (especially in Japan) has been what many have speculated all along: a "currency" against which fiat money can be devalued in hopes of sparking fiat hyperinflation that inflates away record amounts of fiat debt.
