In a major decision this week, the Supreme Court ruled that the Federal Reserve has a historically unique kind of independence from the executive branch and, as a result, the president cannot fire a Fed governor without cause. And that’s very welcome news for investors.

Missed Nvidia in 2009? This Rare Signal Is Flashing Again. In 2009, a “Double Down” signal flashed for a little-known chipmaker called Nvidia. For the first time in years, that same “Total Conviction” signal is flashing for a company 1/100th the size of Nvidia. Continue »

The decision stems from President Donald Trump’s attempts to fire Fed Governor Lisa Cook on allegations that she committed mortgage fraud in 2021 (Cook denies the allegations and the Justice Department investigation into her actions is ongoing).

Many observers of the investigation into Cook believe it was initiated to force her ouster from the Fed and replace her with a governor more amenable to the interest rate cuts Trump wants. The Trump administration also attempted to push former Fed Chair Jerome Powell out prematurely for the same reasons, they hold.

Had the court ruled that Trump could fire Cook without proof of wrongdoing, it would mean that the president (any president) could fire Fed governors at will, without cause. And that would allow a president to reshape the Fed to their liking, which would seriously compromise the Fed’s independence.

Central bank independence promotes economic growth and healthy markets

It bears repeating that central bank independence — which insulates these institutions from political pressure to conduct monetary policy in a specific way — is critical to economic growth and stability, as well as the health of the stock market.

When consumers believe the Fed has the authority to keep inflation under control, they alter their own behavior in ways that mitigate inflation. By contrast, when they doubt the Fed’s credibility, they begin to act in ways that make inflation worse. For example, if consumers expect prices to rise, they accelerate purchases of some items to avoid higher price tags in the future. The resulting surge in current demand drives prices higher, creating the very inflation that many anticipated.

Investors, too, are influenced by inflation expectations. When they believe inflation is going to rise because of political pressure on the Fed to lower rates when it should be hiking, they retreat from risk assets like stocks and move to inflation hedges like gold and silver.

So, inflation expectations can act as a self-fulfilling prophecy. And the Court’s ruling alludes to this idea. According to the decision, which was written by Chief Justice John Roberts, “Not only the fact of independence but also the appearance of independence is key to the Federal Reserve’s design.”
