Established in 1982 as a small agency for financial advisory and securities brokerage, Kaupthing became a major player in the changes in the Icelandic financial market, continually setting trends and being one of the five founding partners of the Icelandic Stock Exchange. In the mid-1990s, Kaupthing widened its focus to include opportunities abroad, becoming the first Icelandic financial institution to operate outside Iceland. Under the leadership of
Sigurður Einarsson, Kaupthing was listed on the Icelandic Stock Exchange in October 2000, at which point the original owners of the bank, the savings banks in Iceland, reduced their holdings, and individuals and institutional investors replaced them as shareholders. Kaupthing Bank shares were listed on the
Stockholm Stock Exchange in 2002. By 9 October 2008, Kaupthing Bank HF was forced into government receivership, only days after a crisis at
Landsbanki placed that bank into government control. Due to the crisis throughout the Icelandic financial system, all trading in the country's equity markets was suspended on 13 October 2008. The events were followed by the collapse of Iceland's banking sector, which led to the
2008–2011 Icelandic financial crisis. On 31 July 2009, internal documents from Kaupthing Bank were leaked:
WikiLeaks exposed a confidential 210-page document listing Kaupthing's exposure to loans ranging from 45 million to 1.25 billion euros. The leaked presentation revealed that the bank had loaned billions of euros to its major shareholders, including a total of €1.43 billion to
Exista and subsidiaries, which own 23% of the bank. On 9 December 2009, Daniel Thordarsson, former asset manager, and Stefnir Ingi Agnarsson, former stockbroker, both of Kaupthing Hf, were sentenced to eight-month prison terms by the Reykjavik District Court. The pair was charged with putting in offers to buy Exista shares six times in January and February last year shortly before the close of business so that the offers would affect the end-of-day value of Exista shares. The charges were of submitting false purchase enquiries and of
share price manipulation. ==Acquisitions, mergers, subsidiaries==
