Romberg became a member of the Social Democratic Party (SPD) in 1989.[5][6] He served as the minister without portfolio in the cabinet of Prime Minister Hans Modrow between 1989 and 1990.[5] Romberg was appointed minister of finance to the cabinet led by Prime Minister Lothar de Maizière on 12 April 1990 following the first free elections of East Germany on 18 March 1990.[7] Romberg was one of the senior social democratic members of de Maizière's cabinet.[8] On 19 May 1990, the West Germany's finance minister, Theo Waigel, and Romberg signed a state treaty to merge their economies and make the West German mark the sole legal currency in both nations by 2 July 1990.[9]
Romberg was removed from office on 15 August 1990 due to his support for the challenging clauses in a political unification treaty governing the allocation of tax revenues. He also angered the West German officials with his continuous demands for more cash help to bail out the weak East German industries and to finance welfare payments.[6] The other reason for his removal was related to the East Germany's rapidly deteriorating economic status.[8] Romberg was also fired due to his warnings about the reunification in terms of its economic burden and his critical and even pessimistic approach towards it.[10][11]
Werner Skowron succeeded Romberg in the post. Following the dismissal of Romberg, SPD left the coalition on 20 August 1990, and called it unconstitutional.[12][13] Until 1994 Romberg served at the European Parliament.[4]
