Book excerpt: To bring fiscal discipline to state and municipal governments, Mexico's federal government has established a two-pillar framework that explicitly renounces federal bail-outs and establishes a Basel - consistent link between the capital-risk weighting of bank loans to subnational governments and the borrower's credit rating. Whether the framework succeeds will depend partly on market assessments of the government's commitment to enforce bank capital rules and refrain from bailing out defaulting subnational governments.
