Nosferatu was a Romanian broker/dealer, headquartered high in the Carpathian mountains. It was an intermediate broker for Lehman brothers and MF Global. It had a long and magnificent history, first clearing Transylvanian futures for the Medicis and Rothschilds, only to meet a sticky end when tulip mania finally broke in 1637. But, miraculously, it lived on, in boxes of sacred earth, only to wreak a similar hell on undercapitalised American brokers in 2008.
