Moral hazard is a concept that has been associated with the mortgage crisis in the US, where large mortgage banks were encouraged to provide loans to almost anyone without quality collateral. After the collapse of these banks, the US government and the US central bank (Fed) invested the capital into these banks to provide them sufficient liquidity. This is an example of moral hazard, where financial institutions can take risks and in case of catastrophic scenario these banks and the management of these banks are not threatened that they would have to be responsible and they follow a simple rule: "too big to fail". The aim of the article is an application of advanced model VaR (Value at Risk) through a time series of income for the corresponding period of the investment portfolio, which consists of eight assets and further the application of this model on stock index SP500, to assess this method in terms of moral hazard. It is primarily about the relevance of this method in practice.
