Kaupthing Bank (Icelandic: Kaupþing banki; Icelandic pronunciation: ​[ˈkʰœiːpˌθiŋk]) was a major international Icelandic bank, headquartered in Reykjavík, Iceland. It was taken over by the Icelandic government during the 2008–2011 Icelandic financial crisis and the domestic Icelandic based operations were spun into a new bank New Kaupthing, which was subsequently renamed Arion Banki. All the non-Icelandic assets and debts remained with the now defunct Kaupthing Bank. Prior to its collapse it also allegedly loaned money to various parties with the purpose of buying Kaupthing shares.
