The largest financial group in the Nordic region, Nordea was, despite warnings from the Swedish Financial Supervisory Authority (FI) active in using offshore companies in tax havens according to the Panama papers. Other Swedish banks were mentioned in the documents, but mention of Nordea occurred 10,902 times and the second-most mentioned bank has 764 matches. In 2012, Nordea asked Mossack Fonseca to change documents retroactively so that three Danish customers power of attorney documents had been in force since 2010. Nordea bank loaned billions of euros to shipping companies that own vessels in secrecy jurisdictions such as Bermuda, Cyprus, Panama, BVI, the Cayman Islands and the Isle of Man. In the Paradise Papers, Nordea was shown to have lent a significant amount of money to customers based in tax havens. As a consequence of the leaked documents, the Swedish Financial Supervisory Authority (FI) stated on 4 April 2016 that it had started an investigation into the conduct of Nordea.
