The proliferation of fake news has become a major problem in today’s more connected digital world, especially for companies that are struggling financially during emergencies like pandemics or recessions. This study explores how disinformation erodes consumer trust in times of crisis, distorts market perceptions, and disrupts supply networks, all of which increase a company’s financial vulnerability. This study uses a mixed-methods approach, combining quantitative analysis of case studies from a variety of industries, such as retail, healthcare, and finance, during the COVID-19 pandemic, the global financial crisis of 2008, and the financial crisis in Nigeria in 2023, with qualitative insights from interviews with business leaders. The results show that there are three main ways in which bogus news exacerbates financial difficulties for businesses. First of all, it causes abrupt changes in consumer behavior, like boycotts or panic buying, which upsets sources of income. Second, false information concerning product safety or supply chain interruptions raises operating expenses and delays, which exacerbates financial strain. Last but not least, bogus news that attacks a company’s reputation lowers investor trust and makes it harder to obtain vital investment. Businesses who were wrongly accused of unethical behavior during the epidemic, for instance, had a sharp decline in stock values, which had long-term effects on the financial recovery. This study emphasizes its real-world economic effects during periods of increased susceptibility and suggests a framework for companies to lessen these impacts, focusing on the open communication and collaborations with reliable media sources to successfully combat false information.
