- Abstract:
- On January 28, 2021, stocks in U.S.-based video game retailer GameStop Corp. reached an all-time high of $483. Two weeks earlier, they had been trading at $20. Two weeks later, they were down again, and a congressional hearing on the matter was underway in Washington. Wild swings are hardly uncommon in financial markets. This episode, however, had novel characteristics. In a recent report, the U. S. Securities and Exchange Commission states that “GameStop Corp and multiple other stocks experienced a dramatic increase in their share price in January 2021 as bullish sentiments of individual investors filled social media.” 1 Retail traders congregating on the Reddit platform were key in both price formation and the emergence of a “Main Street versus Wall Street” narrative around the stock.2 The influence of social media on financial markets is here to stay, as younger generations start saving and investing. This carries both opportunities and risks. Information sharing and discussion on internet platforms can improve market transparency and efficiency. On the other hand, social media platforms are known vehicles of disinformation and manipulation of human behavior. They could be weaponized by malicious actors, ranging from state-sponsored groups to crime syndicates, looking to compromise market integrity and financial stability. For liberal democracies with independent financial watchdogs, a complex policy challenge follows. In order to fight information operations, financial authorities will need to cooperate with intelligence communities and other relevant parts of executive branches. This requires rules that clearly define each party’s role and encourage reciprocal trust. In many jurisdictions, cybersecurity statutes provide a starting point. They are, however, limited in scope, only covering cooperation vis-& agrave;-vis traditional cyber attacks. In this paper, we argue that the model must evolve to help prevent or defend against malicious information operations.3 We highlight, as a first step, the importance of organizational modules that allow entities with different levels of access to classified information to work together to assess and inform responses to hostile operations.
