Kevin Warsh, a defender of the free market and a master of currency, believes that prices (including interest rates) are the most important signals in the market and that governments should not intervene. He has publicly criticized the Federal Reserve for its long-term quantitative easing policy, artificially lowering long-term debt rates, essentially alternative price controls. He believes that central banks should only enter the market as the last lender of last resort only when the market is extremely ineffective, and in other cases, they should allow the market to operate freely. The price discovery process should not be curbed. From this perspective, when the stock market plunges, you cannot expect the Wash-led Federal Reserve to provide the Fed Put (taking steps to stabilize the markets) like previous chairmen since Greenspin. This may also be the most unsettling aspect of the financial markets.
