The Federal Reserve creates and manipulates the dominant fiat currency of the world. It produces the inflation of its supply and the continuous depreciation of its purchasing power. It manipulates dollar interest rates and the cost of debt, makes elastic the availability of credit (especially during financial crises), finances the government, and monetizes federal deficits in amounts limited only by the statutory debt ceiling. It is often imagined to be “managing the economy,” although, in fact, no one can successfully do that. It is a central bank not only to the United States, but to the entire dollar-using world. In short, the Fed is the most powerful financial institution there is or ever has been. That such a power is concentrated in a single, unelected institution is a problem for the constitutional order of the American republic.
Equally fundamental is that the Fed is always subject to deep uncertainty. It has clearly demonstrated its inability (like everyone else’s) to predict the economic or financial future, and it is inherently unable to know what the results of its own actions will be. Its remarkable power combined with its inescapable lack of knowledge of the future makes it the most dangerous financial institution in the world. This is true no matter how intelligent or brilliant its officers may be, however good their intentions, however many hundreds of economists they hire, or however complex the computer models they build.
At the famous Jackson Hole central banking conference in August 2023, Fed Chairman Jay Powell, with admirable candor, pointed out some essential uncertainties in the current Federal Reserve debates. “We cannot identify with certainty the neutral rate of interest, and thus there is always uncertainty” about monetary policy, which is “further complicated by uncertainty about the duration of the lags” with which the policy operates and the “changing dynamics [that] may or may not persist.” He continued, “These uncertainties, both old and new, complicate our task.” They certainly do, and this is true of the Fed’s monetary issues at all times.
Powell used an apt metaphor in this respect: “We are navigating by the stars under cloudy skies.” The President of the European Central Bank, Christine Lagarde, used a different metaphor: “There is no pre-existing playbook for the situation we are facing.” But the former Governor of the Bank of England, Mervyn King, in his book, The End of Alchemy, drew a blunter conclusion from it all: “If the future is unknowable, then we simply do not know and it is pointless to pretend otherwise.”
All this should increase our skepticism about how much independent power central banks should have, and whether there is a meaningful path for reform.
