I suppose that I am thinking of this:
Over time, most cajas colluded with regional political establishments to create a self-serving system of unscrupulous financing for regional governments provided by politically stuffed savings banks’ boards which, in turn, thrived in what has been defined as “a culture of greed, cronyism and political meddling”. This system was exposed in the aftermath of the global financial crisis. As a result, out of the 45 cajas in existence at the start of the crisis in 2007, only two have survived in their initial form. The rest were absorbed by banks, dismantling in effect the cajas model in Spain.
