The existence of an economic crisis for this year (2008) is an event that in if he understands that in a lot of micro events viewed from a global scale can be classified as macro events and acting on some important local economic base not only but also global. A very important point to mention when we talk about the existence of the economic crisis is the foreclosure crisis, since this is one of the factors that affect not only banks but also to customers of the same. The mortgage crisis is a macro event that currently affects the vast majority of financial markets since the emergence of this crisis in the United States preceded the expansion of the same worldwide, especially in European banking markets. The primary bases of the mortgage crisis of 2008, are given in United States since the year 2007 in that country housing demand had doubled and therefore the housing prices had also obtained the conduct, that in a principle did not seem too bad, because bank loans were at their zenith. The financial performance was stable about 4 months, until that behavior affects the loan interest rates worldwide, which made these rates dropped to the point that increased both its lending boom that national banks were no money to pay, forcing them to resort to other entities to borrow money excessively large, while both the interest rate did not produce the income necessary for banks to continue to provide such loans. From this then it preceded the beginning of the mortgage crisis of 2008. At the beginning of 2008 the creation and use of subprime mortgages, was an important source to lessen the impact of the mortgage crisis, since this type of loan was based on giving them more easily, but with the difference that had several points of interest higher than normal loans, and although this at first contributed to lessen the impact of the crisis did not take long for people to cease to get many loans, thus presenting feature that some banks with large debts were caused by the rise of the loans. It is worth mentioning that another important factor affecting the economy was the collapse of the mortgage value of the house, causing so people end up paying more than they really worth that property and thus helping people to cease paying the cancellation or such mortgages. In European Union countries like Spain and France the mortgage crisis was reflected largely in the housing bubble, since the vast amount of expectations for growth in this area had people make important financial transactions, especially mortgage, thereby bringing to a significant slump in the mortgage and investment field, creating an economic slowdown that affected the economy enough bank across the European continent.
