Since the approval of Spain¿s 2012 National Budget on March 30, 2012, some doubts and controversies have added up to many fears in the private sector regarding the measures and stimuli that the Spanish government was going to undertake. At the same time, this situation was in some measure aggravated by the financial backlog of many small and medium companies, which are and will continue, in the following years to be completely unable to comply with their financial requirements. In line with Boronat Ombuena¿s (2009a, 2009b, 2010, 2012) requirements in his new approach to finance and private sector liaisons, the purpose of this paper is to analyze the recent years of the credit sector in Spain as well as its direct and mid-term effects that its mergers and acquisitions (M&A) have contributed up to date, and will still produce in the near future. We will take a closer look at the evolution of the banking sector in Spain from 1995 to 2012 through a historically-based methodology, compiling and synthesizing the existing financial and risk market information and analyzing its evolution. We shall observe that in a single year, the total number of savings banks in Spain decreased from 45 to only 15 entities and that the risks the financial system took over these last few years were not equally distributed across the entities, resulting in an advanced foreclosure of the regional savings banks and in a market-share growth for the commercial banking entities. This process has resulted in creating larger entities and, in some cases, a vacuum of regional and local credit entities that in the mid-long term will eventually end up in a representative loss on credit availability. These circumstances call into question the need for a paradigm change and most importantly, new approaches to solve the new challenges that can result in the financial fluidity of the system and the eventual recovery of the economic structure.
