Supreme Court Sensibly Made Markets Regulation Less Political

Last week, the Supreme Court overturned a decades-old legal doctrine that gave federal regulators the power to interpret unclear laws. This touched off a lot of wild rhetoric about the end of the administrative state. My interest is how scrapping the Chevron ruling will affect financial regulation, but to get some necessary perspective we should start with history.

In the US, the modern administrative state is traditionally traced to the 1887 creation of the Interstate Commerce Commission in response to a public outcry over the conduct of the railroad industry. Over the next 90 years, federal agencies grew in number, size and power with major boosts during the Progressive Era, the New Deal and the Great Society.

All that came crashing down with the economic disaster of the 1970s. Beginning with President Jimmy Carter and his deregulation czar Alfred Kahn, the prevailing winds switched from more regulation to less. While many rules have been passed or tightened since, it’s fair to say that the trend of the last quarter of the 20th century was deregulatory.

The Chevron decision came in 1984, seven years after the high watermark of regulation. So, it clearly was not necessary for the care and feeding of a robust regulatory state. It was, however, supported by those who hoped to stop the Reagan administration from deregulating.

The final historical point is that courts started undermining Chevron before the ink was dry on the decision. This put them on a collision course with activist agencies emboldened by crises such as the bursting of the internet bubble in 2000, the financial crisis of 2007-2009 and Covid. Something had to give eventually. The Supreme Court would have to choose between the power of courts and the power of agencies to resolve ambiguity in legislation. It shouldn’t be a big surprise to anyone that the conservative majority found in favor of the power of courts.
