1980: The Hunt Brothers tried to corner the market, IIRC.
There wasn't any radical shift in fiscal policy in 1980 to justify the rapid spike in silver. There was a major shift, however, in 1971 (1972?) when President Nixon put the USA completely on a fiat (no precious metal backing) currency.
OTOH, the US Treasury and NY Federal Reserve have put at least $4 Trillion USD into the marketplace, vastly expanding the M3 money supply. Very little of this money has reached Main Street to ease the current credit (lines of credit) crisis -- the TBTF|TBTJ Banksters and Wall Street are hanging onto that "new money", propping up crony corporations and foreign central banks which coincidentally are also private for-profit banks. The Federal Reserve refused to inform Congress about exactly how much money they have released, nor to whom. As the double-dip recession begins to bottom out, these Banksters will be buying up Main Street USA and the residential & commercial real estate at pennies on the dollar.
Without fundamental changes, including tightening regulations on commodity futures speculation and increased central bank backing of local bank lines of credit to Main Street, the economic meltdown of September 2008 will be repeated, although it will likely be worse than that of the Great Depression. This would still only be the equivalent of a band-aid on a gushing arterial wound. The fiscal fundamentals of the American economy are unsustainable. Major economic change is on it's way.
The Obama regime, chock full of Banker lobbyist/advisors, has merely been "kicking the economic credit/debt crisis down the street". This is the only way that the USA government can continue to justify the tremendous fiscal drain of maintaining 3-1/2 overseas conflicts, the Departments of Defense & Homeland Security and the National Intelligence infrastructure. Without the prospect of propping up the American Exceptionalism mercantile colonial empire that is based on Oil, the USA dollar as the world's reserve currency will end. When it does end, this country will experience hyper-inflation.
thank you god so well put...
