FROM BLISSFUL IGNORANCE TO PARANOIA
The BIS report, “Asset encumberance, financial reform and the demand for collateral assets,” was prepared by a “Working Group established by the Committee on the Global Financial System,” which happens to be chaired by none other than NYFed President William Dudley, former Chief US Economist for Goldman Sachs. (No, he is not the Chief US Economist referred to earlier in this report, although as explained above these guys are all substitutes for one another in any case.) 
[A]s the financial crisis made painfully clear, the business of liquidity provision inevitably exposes financial intermediaries to various forms of run risk. That is, in response to adverse events, their fragile funding structures, together with the binding liquidity commitments they have made, can result in rapid outflows that, absent central bank intervention, lead banks to fire-sell illiquid assets or, in a more severe case, to fail altogether. And fire sales and bank failures–and the accompanying contractions in credit availability–can have spillover effects to other financial institutions and to the economy as a whole. Thus, while banks will naturally hold buffer stocks of liquid assets to handle unanticipated outflows, they may not hold enough because, although they bear all the costs of this buffer stocking, they do not capture all of the social benefits, in terms of enhanced financial stability and lower costs to taxpayers in the event of failure. It is this externality that creates a role for policy. 
[Newton’s] third law of universal motion was that for each and every action there is an equal and opposite reaction. While applicable to the natural world, it does not hold with respect to the actions of financial markets and the subsequent reactions of central banks and other regulators. Indeed, the reactions of regulators are consistently disproportionate to the actions of financial markets. In sinister dialectical fashion, the powers assumed and mistakes made by policymakers tend to grow with each crisis, ?thereby ensuring that future crises become progressively more severe...[W]as the Fed’s policy reaction to the 1987 crash proportionate or even appropriate? Was it “an equal but opposite reaction” which merely temporarily stabilised financial markets or did it, in fact, implicitly expand the Fed’s regulatory role to managing equity prices? Indeed, one could argue that this was merely the first of a series of progressively larger “Greenspan Puts” which the Fed would provide to the financial markets during the 18 years that the so-called “Maestro” was in charge of monetary policy and, let’s not forget, bank regulation...By the late 1980s, a huge portion of the S&L industry was insolvent. The recession of 1990-91, made a bad situation worse. FSLIC funds were rapidly depleted. But a federal guarantee is supposed to be just that, a guarantee, so Congress put together a bailout package for the industry. A new federal agency, the Resolution Trust Corporation (RTC), issued bonds fully backed by the US Treasury and used the proceeds to make insolvent S&L depositors whole...In retrospect, the entire S&L debacle, from its origins in regulatory changes and government guarantees, through the risky lending boom, bust, credit crunch and fiscal and monetary bailout can be seen as a precursor to the far larger global credit bubble and bust of 2003-2008: Just replace the S&Ls with Fannie/Freddie and the international shadow banking system. But there is no need to change the massive moral hazard perpetrated by incompetent government regulators, including of course the Fed, and the reckless financial firms who played essentially the same role in both episodes.
MIGHT COLLATERAL TRANSFORMATION BE THE CRUX OF THE NEXT CRISIS?
