A Limited Central Bank

As the Fed begins its 100th anniversary year, I believe it is entirely appropriate to reflect on its history and its future. At the same time, we need to reflect on what I believe is the Federal Reserve’s essential role and how it might be improved as an institution to better fulfill that role.1

Douglass C. North was cowinner of the 1993 Nobel Prize in Economics for his work on the role that institutions play in economic growth.2 North argued that institutions were deliberately devised to constrain interactions among parties both public and private. In the spirit of North’s work, one theme of this essay will focus on the fact that the institutional structure of the central bank matters. The central bank’s goals and objectives, its framework for implementing policy, and its governance structure all affect its performance.

Central banks have been around for a long time, but they have clearly evolved as economies and governments have changed. Most countries today operate under a fiat money regime, in which a nation’s currency has value because the government says it does. Central banks are usually given the responsibility to protect and preserve the value or purchasing power of the currency.3 In the U.S., the Fed does so by buying or selling assets in order to manage the growth of money and credit. The ability to buy and sell assets gives the Fed considerable power to intervene in financial markets not only through the quantity of its transactions but also through the types of assets it can buy and sell. Thus, it is entirely appropriate that governments establish their central banks with limits that constrain the actions of the central bank to one degree or another.



Yet, in recent years, we have seen many of the explicit and implicit limits stretched. The Fed and many other central banks have taken extraordinary steps to address a global financial crisis and the ensuing recession. These steps have challenged the accepted boundaries of central banking and have been both applauded and denounced. For example, the Fed has adopted unconventional largescale asset purchases to increase accommodation after it reduced its conventional policy tool — the federal funds rate — to near zero. These asset purchases have led to the creation of trillions of dollars of reserves in the banking system and have greatly expanded the Fed’s balance sheet. But the Fed has done more than just purchase lots of assets; it has altered the composition of its balance sheet through the types of assets it has purchased. I have spoken on a number of occasions about my concerns that these actions to purchase specific (non-Treasury) assets amounted to a form of credit allocation, which targets specific industries, sectors, or firms. These credit policies cross the boundary from monetary policy and venture into the realm of fiscal policy.4 I include in this category the purchases of mortgage-backed securities (MBS) as well as emergency lending under Section 13(3) of the Federal Reserve Act, in support of the bailouts, most notably of Bear Stearns and AIG. Regardless of the rationale for these actions, one needs to consider the long-term repercussions that such actions may have on the central bank as an institution.

As we contemplate what the Fed of the future should look like, I will discuss whether constraints on its goals might help limit the range of objectives it could use to justify its actions. I will also consider restrictions on the types of assets it can purchase to limit its interference with market allocations of scarce capital and generally to avoid engaging in actions that are best left to the fiscal authorities or the markets. I will also touch on governance and accountability of our institution and ways to implement policies that limit discretion and improve outcomes and accountability.

Goals and Objectives

The Federal Reserve’s goals and objectives have evolved over time. When the Fed was first established in 1913, the U.S. and the world were operating under a classical gold standard. Therefore, price stability was not among the stated goals in the original Federal Reserve Act. Indeed, the primary objective in the preamble was to provide an “elastic currency.”
