"Effective regulation built around sound capital standards will limit leverage and risk. For example, the investment banks that are reconfiguring to become bank holding companies will become subject to capital standards that reduce the magnitude of the risk they are allowed to take. The capital standards they were subject to previously allowed them to leverage their balance sheets 30 to 1 and higher, meaning that for every dollar in their coffers, they could place bets of $30. In contrast, the rigorous capital requirements and standards to which insurance companies are subject have effectively limited the risks that insurers can take.
Insurance companies must set aside reserves using a formula that calculates future obligations based on conservative risk and interest-rate assumptions. A further layer of protection comes from the requirement to set aside additional "risk-based capital" for other contingencies. Insurance regulations also prescribe a prudent and diverse mix of investments whose expected cash flows reasonably match future obligations.
No regulatory regime can prevent all failures, particularly when the capital markets are dysfunctional. But these three layers of capital protection greatly limit the systemic risks and costs to taxpayers when something goes wrong. "
Here's my comment:
Even the most knowledgeable and assiduous regulators have limited capacity to halt irresponsible risk-taking and speculation."
This is absolutely correct. The only thing that I would add is transparency. In other words, the trade must be spelled out clearly, and the risks, especially if they are shifted to a third party, need to be clearly defined. Otherwise, it is very hard to determine the correct amount of capital needed.
