a specified time in the future, in which the supply of financial services no longer satisfies demand according to regulatory criteria, qualified by a measure of uncertainty about the system's future behaviour, in the absence of new mitigation efforts." This definition lends itself to practical risk mitigation applications, as demonstrated in recent research by a simulation of the collapse of the Icelandic financial system in circa 2008. Systemic risk should not be confused with market or price risk as the latter is specific to the item being bought or sold and the effects of market risk are isolated to the entities dealing in that specific item. This kind of risk can be mitigated by hedging an investment by entering into a mirror trade. Insurance is often easy to obtain against "systemic risks" because a party issuing that insurance can pocket the premiums, issue dividends to shareholders, enter insolvency proceedings if a catastrophic event ever takes place, and hide behind limited liability. Such insurance, however, is not effective for the insured entity. One argument that was used by financial institutions to obtain special advantages in bankruptcy for derivative contracts was a claim that the market is both critical and fragile. Systemic risk can also be defined as the likelihood and degree of negative consequences to the larger body. With respect to federal financial regulation, the systemic risk of a financial institution is the likelihood and the degree that the institution's activities will negatively affect the larger economy such that unusual and extreme federal intervention would be required to ameliorate the effects. A general definition of systemic risk which is not limited by its mathematical approaches, model assumptions or focus on one institution, and which is also the first operationalizable definition of systemic risk encompassing the systemic character of financial, political, environmental, and many other risks, was put forth in 2010. The Systemic Risk Centre at the London School of Economics is focused on the study of systemic risk. It finds that systemic risk is a form of endogenous risk, hence frustrating empirical measurements of systemic risk. Measurement TBTF/TCTF According to the Property Casualty Insurers Association of America, there are two key assessments for measuring systemic risk, the "too big to fail" (TBTF) and the "too (inter)connected to fail" (TCTF or TICTF) tests. First, the TBTF test is the traditional analysis for assessing the risk of required government intervention. TBTF can be
