Já descobri o que é a “mão invisível” da economia hayekiana e neoliberal que determina a “eficiência do mercado”:
Um corretor (e não “corrector”, com “c”) de uma empresa americana comprou, durante a noite de 29 para 30 de Junho, 520 milhões de US Dollars em futuros de petróleo — ¡ comprou 69% do mercado global disponível ! — , o que fez com que o preço do petróleo no mercado internacional subisse a pique.
Quando foi interrogado pela empresa para saber por que tinha feito essa compra durante a noite, o corretor explicou que não se lembrava de nada porque passou a noite bêbedo. Portanto, da próxima vez que a gasolina subir, provavelmente há um americano bêbedo que explica a “mão invisível da eficácia do mercado”.

On June the 30th 2009 oil mysteriously jumped by more than $1.50 a barrel during the night, to reach its highest price in eight months, the kind of swing that is caused by a major geopolitical event.
The amazing, true cause of this price spike has now been released by a Financial Services Authority investigation (FSA).
Although not authorised to invest company cash in trades Steve Perkins, a long standing, senior broker at PVM Oil Futures, had managed to spend $520 million on oil futures contracts throughout the night.
On the morning of the 30th an admin clerk called Mr Perkins to ask why he had bought 7 million barrels of crude during the night. Mr Perkins had no recollection of the transactions, and it turned out that he had made the trades during a “drunken blackout.”
By the time PVM had realised the transactions had not been authorised by a client, they had incurred losses of $9,763,252.
Between the hours of 1.22am and 3.41am, Mr Perkins gradually bought 69 percent of the global market, whilst driving prices up from $71.40 to $73.05, by bidding higher each time.
