During his time in office, Rüttgers came under severe criticism for failing to mend the state's public finances. One of the reasons was the crisis at the state-owned lender WestLB, which led his government to set aside 1.5 billion in 2008. Rüttgers long wanted the bank to stay independent and categorically ruled out a merger with LBBW. However, by 2007, he and Roland Koch, his counterpart from the state of Hesse, agreed on approving a merger of their respective state-owned banks, WestLB and Landesbank Hessen-Thüringen (Helaba). WestLB was eventually broken up in 2012 after years of losses and controversy.
