大田金業讲故事：瑞银魔鬼交易员惹祸端
雷曼兄弟倒闭3周年之际，一则消息又让投资者的心揪到了嗓子眼。2011年9月15日，伦敦警方逮捕了瑞士银行集团交易员奎库·阿多博利，罪名为滥用职权从事欺诈和伪造账目。阿多博利被指控进行未授权交易，导致瑞银集团（UBS)损失20亿美元。9月16日，UBS承认，其投资银行部门交易员进行的一项未经授权的交易，可能对其造成20亿美元的损失。消息传出后，UBS股价应声下跌，一度探低至9.88瑞士法郎，跌幅达9.6%。
瑞银的巨额损失全拜这位魔鬼交易员所赐，而一位交易员创造出高达20亿美元的损失，也着实令市场惊愕。这位交易员本年以为瑞士法郎汇率会上升，但由于瑞士中央银行突然干预市场，导致了瑞士法郎对欧元大幅度贬值，该笔交易出现了巨额亏损。
实际上交易员交易的额度是有限制的，但是这可难不住“聪明”的交易员们，他们可以伪造反向交易，这样事实上单边交易的额度就可以无限扩大。他们有时也利用系统设置的漏洞，进行非同类产品的反向交易，也使得交易员的单边交易限额扩大。
2011年9月24日，UBS首席执行官奥斯瓦尔德·格吕贝尔因交易员阿多博利违规交易造成重大损失而引咎辞职，结束了其在瑞士银行业40多年的职业生涯，令人惋惜。
从受次贷危机严重冲击到此次违规交易造成的巨额损失，UBS近年屡遭困境。在次贷危机时期，UBS出现多年来的首度亏损。之后，随着市场条件恶化，金融危机爆发，UBS损失进一步加重，并数次大规模裁员。最后，瑞士政府出巨资救助UBS，瑞士央行收购了UBS危机后无法处理的400亿美元不良资产。
