The credit-ratings-uranium enrichment process.

By allowing the banks to hold extremely little capital when lending or investing in what is officially considered as having no risk, like triple-A rated securities and infallible sovereigns, Basel bank regulations instruct and give the banks huge incentives to believe and follow what the credit ratings indicate immensely more when the ratings are good, than when they are bad.

In other words, the capital requirements for banks, serve as hallucinogens given to bankers in order to exaggerate their reactions to the signals the credit ratings emit.
