Risk is inevitable in banking; in fact, it’s what makes banking profitable. The question is, how much risk is acceptable? Recognizing that existing techniques of measurement were sometimes misleading and arbitrary, Plansmith developed a simple calculation called "Margin Risk Tolerance" that defines how much risk each bank can take. Despite the wealth of banking information Plansmith has at hand, we believe risk relates to the individual bank, and cannot be measured to any peer standard or magic number.
Margin risk tolerance calculates the minimum net interest income and net interest margin necessary to maintain continuing operations. Minimum margin consists of two basic components: 1) earnings needed to maintain an acceptable capital ratio and pay dividends, and 2) earnings needed for overhead.
