funding advantage compared with other banks, which some call an implicit subsidy. There are a number of policy approaches—some complementary, some conflicting—to coping with the TBTF problem, including providing government assistance to prevent TBTF firms from failing or systemic risk from spreading; enforcing “market discipline” to ensure that investors, creditors, and counterparties curb excessive risk-taking at TBTF firms; enhancing regulation to hold TBTF firms to stricter prudential standards than other financial firms; curbing firms’ size and scope, by preventing mergers or compelling firms to divest assets, for example; minimizing spillover effects by limiting counterparty exposure; and instituting a special resolution regime for failing systemically important firms. A comprehensive policy is likely to incorporate more than one approach, as some approaches are aimed at preventing failures and some at containing fallout when a failure occurs.”
