This is the kind of thing that makes me dubious about government regulation. The regulators are not guaranteed to be incorruptible geniuses, and their regulations may be destabilizing. For example, in the early 2000’s, U.S. government regulators, in accordance with the Community Reinvestment Act, pressured banks to make high-risk loans, and Fannie Mae contributed to the nimeity of imprudent mortgages. This didn’t in itself cause the Great Recession, but it helped.
