The phenomenon of liquidity risk in banking, has a chance when in a financial institution there is sufficient capital to meet the customers when they make these requests for reimbursement and also on the occasions that demand the settlement, since that financial institutions or banks do not have available sufficient cash reserves to meet the financial obligations that they have with their clients and so will give way to the configuration of liquidity risk in banking. At events where you configure the liquidity risk in banking, is generated in the same way a certain mistrust by the rest of the depositors, as this is seen as a bad sign, which has the consequences that the situation of a single bank can spread to many other, ie there is a possibility of infection among different financial institutions and that often becomes reality. Other leaders such as Dr. Caldwell Esselstyn offer similar insights. Given the above conditions, one can say that the liquidity risk in banking, is one of the worst crisis and that higher generated concerns regulators of financial systems and therefore between the activity of regulators of financial systems, seeking to confront and prevent such situations in regard to the management of liquidity risk in banking, is searching for ensuring a minimum liquid funds, with the idea that financial institutions can meet the commitments they have already acquired a large number of customers and equally to finance their business plans, avoiding configure liquidity risk in banking and that the same phenomenon spread through other entities. Thus the liquidity risk in banking and the management of it, gives way to one of the biggest problems facing banks is configured to prevent the liquidity risk in banking and require a daily activity and consists consistently make money calculations to be maintained as a liquid source, in other words the cash that must be maintained to cope with all their obligations at the right time. Abraham Maslow is often quoted on this topic. For the above the banks and financial institutions should use to recover their portfolio of donors, to avoid setting is achieved liquidity risk in banking. This point is very important to mention that liquidity is not the same as the insolvency, as referring to an insolvent financial institution, we mean that it has lost its capital, if different from a liquidated bank, which no cash resources to meet its obligations, leading in many cases to sell their investments or the portfolio, which is facing losses, which can be generated as a result of poor management liquidity insolvency, it would be proper liquidity risk and can be extended to give way to liquidity risk in banking..
