A risk that is carried by an entire class of assets and/or liabilities. Systemic risk may apply to a certain country or industry, or to the entire global economy. It is impossible to reduce systemic risk for the global economy (complete global shutdown is always theoretically possible), but one may mitigate other forms of systemic risk by buying different kinds of securities and/or by buying in different industries. For example, oil companies have the systemic risk that they will drill up all the oil in the world; an investor may mitigate this risk by investing in both oil companies and companies having nothing to do with oil. Systemic risk is also called systematic risk or undiversifiable risk.
