Understanding the Intervenist Impulse of the Modern Central Bank

The financial crisis of 2007 and 2008 was a watershed event for the Federal Reserve and other
central banks. The extraordinary actions they took have been described, alternatively, as a natural
extension of monetary policy to extreme circumstances, or as a problematic exercise in credit
allocation. I have expressed my view elsewhere that much of the Fed’s response to the crisis falls
in the latter category rather than the former.1 Rather than reargue that case, I want to take this
opportunity to reflect on some of the institutional reasons behind the prevailing propensity of
many modern central banks to intervene in credit markets. As always, these remarks are my own
and the views expressed are not necessarily shared by my colleagues on the Federal Open
Market Committee.2
There is widespread agreement among economists that a vigorous monetary policy response can
be necessary at times to prevent a contraction from becoming a deflationary spiral. Financial
market turmoil often sparks a flight to monetary assets. In the 19th and 20th centuries, this often
took the form of shifts out of deposits and into notes and specie. Under a fractional reserve
banking system, this necessitates a deflationary contraction in the overall money supply unless
offset through clearinghouse or central bank expansion of the note supply. In modern financial
panics, banks often seek to hoard reserve balances, which again would be contractionary absent
an accommodating increase in the central bank reserve supply. In both cases, the need is for an
increase in outstanding central bank monetary liabilities.
The Fed’s response during the financial crisis was not purely monetary, however. In the first
phase of the crisis — from the fall of 2007 through the summer of 2008 — its credit actions were
sterilized; lending through the Term Auction Facility and in support of the merger of Bear
Stearns and JPMorgan Chase was offset by sales of U.S. Treasury securities from the Fed’s
portfolio. (Note that such sterilized actions are equivalent to issuing new U.S. Treasury debt to
the public and using the proceeds to fund the lending.) It wasn’t until September 2008 that the
supply of excess reserves began to increase significantly. This expansion was accomplished
through the acquisition of an expanding set of private assets — loans to banks and other financial
institutions and later mortgage-backed securities and debt issued by Fannie Mae and Freddie
Mac. While some observers describe this phase of the Fed’s response as a standard, monetary
expansion in the face of a deflationary threat, the Fed’s own characterization often emphasized
instead the intent to provide direct assistance to dysfunctional segments of the credit markets.
Clearly, an equivalent expansion of reserve supply could have been achieved via purchases of
U.S. Treasury securities — that is, without credit allocation.

Like the Fed, the European Central Bank and other central banks have pursued credit allocation
in response to the crisis.
The impulse to reallocate credit certainly reflects an earnest desire to fix perceived credit market
problems that seem within the central bank’s power to fix. My sense is that Federal Reserve
credit policy was motivated by a sincere belief that central banks have a civic duty to alleviate
significant ex post inefficiencies in credit markets. But credit allocation can redirect resources
from taxpayers to financial market investors and, over time, can expand moral hazard and distort
the allocation of capital. This implies a difficult and contentious cost-benefit calculation. But no
matter how the net benefits are assessed, central bank intervention in credit markets will have
distributional consequences.
Central bank credit allocation is therefore bound to be controversial. Indeed, such actions taken
by the Fed over the last few years have generated a level of invective that has not been seen in a
very long time. Critics have sought to exploit the resentment of credit market rescues for partisan
political advantage. While it is easy to deplore politically motivated attempts to influence Fed
policy, we need to recognize the extent to which some measure of antagonism is an
understandable consequence of the Fed’s own credit policy initiatives.
The inevitable controversy surrounding central bank intervention in credit markets is one reason
many observers have long advocated keeping central banks out of credit allocation.3 Central
bank lending undermines the integrity of the fiscal appropriations process, and while U.S. fiscal
policymaking may not inspire much admiration these days, it is subject to the checks and
balances provided for by the Constitution. Contentious disputes about which credit market
segments receive support, and which do not, can entangle the central bank in political conflicts
that threaten the independence of monetary policymaking.
The independence that the modern central bank has to control the monetary policy interest rate
emerged in stages following the end of World War II. The Treasury-Fed Accord of 1951 freed
the Fed from the wartime obligation to depress the Treasury’s borrowing costs. The collapse of
the gold standard in the early 1970s and the attendant bouts of inflation led the Fed in 1979 to
assert responsibility for low inflation as a long-term objective of monetary policy.4 The
independent commitment of central banks to low inflation provides a nominal anchor to
substitute for the anchor formerly provided by the gold standard.
The substantial measure of independence central banks were given was a key element in their
relative success at sustaining low inflation over the last few decades. In fact, many other
countries have adopted frameworks that hold their central banks accountable for a price stability
goal, while allowing them to set interest rate policy independently in pursuit of their goals. This
instrument independence has been critical to insulating monetary policymaking from electionrelated political pressures that can detract from longer-term objectives.
The cornerstone of central bank independence is the ability to control the amount of monetary
liabilities it supplies to the public. But as a by-product, many central banks retain the ability to
independently control the composition of their assets as well. For most modern central banks,
standard policy in normal times is to restrict asset holdings to their own country’s government
2

debt. Some hold gold as well, a vestige of the gold standard. In addition, many make short-term
loans to banks, either to meet temporary liquidity needs or as part of clearing and settlement
operations; both are vestiges of the origin of central banks as nationalized clearinghouses.
The ability of a central bank to intervene in credit markets using the asset side of its balance
sheet creates an inevitable tension. The desire of the executive and legislative branches to
provide governmental assistance to particular credit market participants can rise dramatically in
times of financial market stress. At such times, the power of a central bank to do fiscal policy
essentially outside the safeguards of the constitutional process for appropriations makes it an
inviting target for other government officials. Central bank lending is often the path of least
resistance in a financial crisis. The resulting political entanglements, as we have seen, create
risks for the independence of monetary policy.
This tension is a classic time consistency problem. Central bank rescues serve the short-term
goal of protecting investors from the pain of unanticipated credit market losses, but dilute market
discipline and distort future risk-taking incentives. Over time, small “one-off” interventions set
precedents that encourage greater risk taking and increase the odds of future distress.
Policymakers then feel boxed in and obligated to intervene in ever larger ways, perpetuating a
vicious cycle of government safety net expansion.
The conundrum facing central banks, then, is that the balance sheet independence that proved
crucial in the fight to tame inflation is itself a handicap in the pursuit of financial market
stability. The latitude the typical central bank has to intervene in credit markets weakens its
ability to discourage expectations of future rescues and thereby enhance market discipline.
Solving this conundrum and containing the impulse to intervene requires one of two approaches.
A central bank could seek to build and maintain a reputation for not intervening, in much the
way the Fed and other central banks established credibility for a commitment to low inflation in
the 1980s. Alternatively, explicit legislative measures could constrain central bank lending. The
Dodd Frank Act took steps in this direction by banning loans to individual nonbank entities. But
Reserve banks retain the power to lend to individual depository institutions and to intervene in
particular credit market segments in “unusual and exigent circumstances” through credit
programs with “broad-based eligibility.”5 In addition, the Fed can channel credit by purchasing
the obligations of government-sponsored enterprises, such as Fannie Mae and Freddie Mac.
Constraining central bank lending powers would appear to conflict with the popular perception
that serving as a “lender of last resort” is intrinsic to central banking. But even here, I think our
historical doctrines and practices should not escape reconsideration. The notion of the central
bank as a lender of last resort derives from an era of commodity money standard, when central
bank lending in a crisis was the way to expand currency supply to meet a sudden increase in
demand. Indeed, the preamble to the Federal Reserve Act says its purpose is “to furnish an
elastic currency,” not to furnish elastic credit. The Fed could easily manage the supply of
monetary assets through purchases and sales of U.S. Treasury securities only.6 While it might
sound extreme, I believe that a regime in which the Federal Reserve is restricted to hold only
U.S. Treasury securities purchased on the open market is worthy of consideration.7

It might seem easy to criticize such a regime by reference to what it would have prevented the
Fed from doing in the recent crisis. But that’s the wrong frame of reference, I believe — it’s an
ex post, rather than an ex ante, perspective. Such a regime, if credible, would over time force
changes in market practices that would alter the likelihood and magnitude of crises and the
behavior of private market arrangements during a crisis. It would strengthen market discipline
and incent institutions to operate with more capital and less short-term debt funding — changes
we are now trying to achieve through regulatory means. The relative costs and benefits of such a
regime may be difficult to map out conclusively. But I believe this tradeoff is well worth
studying.
Ten years ago, my former colleagues Al Broaddus and Marvin Goodfriend argued that the design
of central bank asset policy is “part of the unfinished business of building a modern, independent
Federal Reserve.”8 The 1951 Treasury-Fed Accord provided for independent Federal Reserve
control of its liabilities, a necessary ingredient in monetary policy independence. But the
accompanying power to use the Fed’s asset portfolio to intervene in credit markets threatens to
diminish that independence. Sorting out the conundrum of central bank asset policy should be
high on the agenda for all those interested in improving the practice of central banking.

The market supply of such securities is likely to be quite ample for some time to come. But even if the supply
should shrink, as it did a decade ago, the Treasury could arrange to issue in sufficient quantities to allow the Fed to
conduct monetary policy on a Treasuries-only basis. See Broaddus and Goodfriend.
