Financial risk is any of various types of risk associated with financing, including financial transactions that include company loans in risk of default. Often it is understood to include only downside risk, meaning the potential for financial loss and uncertainty about its extent. A science has evolved around managing market and financial risk under the general title of modern portfolio theory initiated by Dr. Harry Markowitz in 1952 with his article, "Portfolio Selection". In modern portfolio theory, the variance (or standard deviation) of a portfolio is used as the definition of risk. Types According to Bender and Panz (2021), financial risks can be sorted into five different categories. In their study, they apply an algorithm-based framework and identify 193 single financial risk types, which are sorted into the five categories market risk, liquidity risk, credit risk, business risk and investment risk. Market risk The four standard market risk factors are equity risk, interest rate risk, currency risk, and commodity risk: Equity risk is the risk that stock prices in general (not related to a particular company or industry) or the implied volatility will change. When it comes to long-term investing, equities provide a return that will hopefully exceed the risk free rate of return The difference between return and the risk free rate is known as the equity risk premium. When investing in equity, it is said that higher risk provides higher returns. Hypothetically, an investor will be compensated for bearing more risk and thus will have more incentive to invest in riskier stock. A significant portion of high risk/ high return investments come from emerging markets that are perceived as volatile. Interest rate risk is the risk that interest rates or the implied volatility will change. The change in market rates and their impact on the profitability of a bank, lead to interest rate risk. Interest rate risk can affect the financial position of a bank and may create unfavorable financial results. The potential for the interest rate to change at any given time can have either positive or negative effects for the bank and the consumer. If a bank gives out a 30-year mortgage at a rate of 4% and the interest rate rises to 6%, the bank loses and the consumer wins. This is an opportunity cost for the bank and a reason why the bank could be affected financially. Currency risk is the risk that foreign
