If the banksters aren't screaming in pain and threatening suicide...
We're still trapped in "the doom loop" (PDF):
These five strategies are the latest incarnation of efforts by the banking system to boost shareholder returns and, whether by accident or design, game the state. For the authorities, it poses a dilemma. Ex-ante, they may well say “never again”. But the ex-post costs of crisis mean such a statement lacks credibility. Knowing this, the rational response by market participants is to double their bets. This adds to the cost of future crises. And the larger these costs, the lower the credibility of “never again” announcements. This is a doom loop.
The “St Petersburg paradox” explains how a gambling strategy which starts small but then doubles-up in the event of a loss can yield positive (indeed, potentially infinite) expected returns. Provided, that is, the gambler has the resources to double-up in the face of a losing streak. The St Petersburg lottery has many similarities with the game played between the state and the banks over the past century or so. The banks have repeatedly doubled-up. And the state has underwritten any losing streak.
