Lehman Brothers collapsed in September of 2008 after months of credit-crunched volatility, and various pundits have made comparisons to this year as sovereign debt woes in America and Europe caused wild market gyrations throughout 2011.
Also back in 2008, Goldman Sachs crunched through the figures to report that September was a bad trading month for US markets in the previous 57 years.
What prompted last night's carnage was the Federal Reserve Bank's decision to put downward pressure on longer term interest rates by "twisting" the yield curve on US government bonds.
But investors in the US and Europe expected more stimulus than what has been labelled as "operation twist" - resulting in widespread market sell offs.

London Metal Exchange cash copper prices closed at $US7653 a tonne last night - down a frightening 11.7% since Friday.
