Financial management concerns decisions regarding retained earnings, debts, investments, dividends, valuation, cash-holding, and other transactions impacting firms’ financial status. Building on the theory of institutional logic, we propose a reformation of financial management informed by stakeholder capitalism, replacing the current practice rooted in ideas of shareholder capitalism. By prescribing a mindset valuing the margin of safety, we gainsay conventional financial thinking and the ultimate strive for financial efficiency and profit maximization. We justify such a shift in practice by portraying predictions as treacherous and the conventional understanding of risk as hazardous. Although we recognize that financial decisions are contextual and influenced by circumstances, we advocate for a generic mindset striving for financial sufficient before financial efficiency, intending to engender increased global economic resilience. As a result, we rationalize the need to replace the current mathematical optimization doctrine with a sufficient doctrine recognizing firms’ responsibility toward stakeholders and society. Anchored in such a mindset, we propose eight guiding principles for the global practice of financial management that we believe will contribute to a more economically sustainable society
