During Nicolae Ceaușescu's communist regime, Dăianu worked for the Securitate's Foreign Intelligence Unit (DIE),[3] between 1976 and September 1978. He left DIE in 1978, of his own volition and he became known, in the following decade, for his writings against Ceaușescu's economic policy, which were highlighted on Radio Free Europe (RFE) at the time. Between 1979 and 1990, he was a researcher at the Economic Socialist Institute. In September 2007, the National Council for Analyzing the State Security Department Files (CNSAS) decided that Dăianu had worked for the External Intelligence Unit solely on economic issues.[4]
Public service career
Between 1992 and 1997, Dăianu was the Chief Economist of the National Bank of Romania. He was the Finance Minister of Romania between December 5, 1997, and September 23, 1998, in the governments of Victor Ciorbea and Radu Vasile. He was dismissed because he refused to endorse a controversial deal with Bell Helicopter Textron to purchase 96 AH-1RO Dracula attack helicopters (a variant of AH-1 Cobra), in order to help modernize the armed forces. Dăianu considered that terms of the contract were disadvantageous for the Romanian industry and that the deal was too costly for the Romanian budget at that time.
In August 2005, he became President of the Supervision Board of Banca Comercială Română, a position previously held by Sebastian Vlădescu and Florin Georgescu [ro], among others. He resigned this post in December 2007, in order to avoid any conflict of interest with his duties as a member of the European Parliament. During 2012–13 he was a member of the Board of CEC Bank. Dăianu was also the President of the European Association for Comparative Economic Studies (EACES), between 2002 and 2004.
He was a member of the European Parliament between 2007 and 2009, when he represented the National Liberal Party (PNL). He was co-rapporteur of the report "Lamfalussy follow-up: Future Structure of Supervision", for the European Parliament. On May 22, 2008, Dăianu, together with three former Presidents of the European Commission, nine former Prime Ministers of EU member states, and six former Finance/Economy Ministers, co-signed an article with title "Financial Markets Cannot Govern Us" in "Le Monde", in which they anticipated the extent of the economic crisis and talked about its causes. In October 2008, Dăianu took position against European banks that receive state aids to get out of the crisis, yet damage emerging European economies through speculation against national currencies.[5]
During the presidential elections of 2009, he was touted as one of possible prime ministers. In 2010, Dăianu was invited to be a fellow of the Warsaw-based Center for Social and Economic Research (CASE). Between 2014 - 2019, he was a member of the Board of the National Bank of Romania. Between April 2013 and June 2014, he was first deputy president of the Romanian Financial Supervision Authority. He is the president of the Romanian Fiscal Council since 2019. Daniel Dăianu is a member of the High Level Group on Own Resources of the European Union, which is headed by Mario Monti. Dăianu is also a member of the European Council for Foreign Relations, since 2012.
