Ending Too Big to Fail

More than six years after the Dodd-Frank Act passed in July 2010, the controversy over how to end “too big to fail” (TBTF) remains a key focus of financial reform. Indeed, TBTF—which led to the troubling bailouts of financial behemoths in the crisis of 2007-2009—is still one of the biggest challenges in reducing the probability and severity of financial crises. By focusing on the largest, most complex, most interconnected financial intermediaries, Dodd-Frank gave officials a range of crisis prevention and management tools. These include the power to designate specific institutions as systemically important financial institutions (SIFIs), a broadening of Fed supervision, the authority to impose stress tests and living wills, and (with the FDIC’s “Orderly Liquidation Authority”) the ability to facilitate the resolution of a troubled SIFI. But, while Dodd-Frank has likely made the U.S. financial system safer than it was, it does not go far enough in reducing the risk of financial crises or in ensuring credibility of the resolution mechanism (see our earlier commentary here, here and here). It also is exceedingly complex.

Against this background, we welcome the work of the Federal Reserve Bank of Minneapolis and their recently announced Minneapolis Plan to End Too Big to Fail (the Plan). While the Plan raises issues that require further consideration—including the potential for regulatory arbitrage and the calibration of the tools on which it relies—it is straightforward, based on sound principles, and focuses on cost-effective tools. In this sense, the Plan represents a big step forward...

Policy rules

Monetary economists like rules. Traditionally, they worry that policymakers will sacrifice the long-term benefits of price stability for the more immediate gratification of higher growth. Realizing how hard it is to resist temptation, politicians have delegated monetary policy to a central bank that is independent, but subject to a mandate that constrains their discretion. This institutional setup helped lower inflation in the advanced economies from a median exceeding 10 percent in the late 1970s and early 1980s to about 2 percent by the late 1990s.

But, convinced that overly accommodative financial conditions in the first few years of the century spurred the credit accumulation that fed the 2007-09 financial crisis, there is a push to constrain central banks further by requiring that they publish and account for their actions with reference to a simple policy rule...

Monetary Policy and Financial Stability

In June 2015, a committee of Federal Reserve Bank Presidents conducted a “macroprudential tabletop exercise”—a kind of wargame—to determine what tools to use should risks to financial stability arise in an environment when growth and inflation are stable. The conventional wisdom—widely supported in policy pronouncements and in a range of academic studies—is that the appropriate tools are prudential (capital and liquidity requirements, stress tests, margin requirements, supervisory guidance and the like). Yet, in the exercise, the policymakers found these tools more unwieldy and less effective than anticipated. As a result, “monetary policy came more quickly to the fore as a financial stability tool than might have been thought.”

This naturally leads us to ask whether there are circumstances when central bankers should employ monetary policy tools to address financial stability concerns. Making the case for or against use of monetary policy to secure financial stability is usually based on assessing the costs and benefits of a policy that "leans against the wind" (LAW) of financial imbalances...

Bank of Japan at the Policy Frontier

Since Governor Haruhiko Kuroda took office in March 2013, the Bank of Japan (BoJ) has been the most aggressively expansionary advanced-economy central bank. Its announcement last month of a “new framework for strengthening monetary easing”—coming only six months after introducing negative policy rates—distances it even further from the pack.

That a central bank is willing to assess its performance transparently and to consider new approaches to achieving its key goals is something we have come to expect. While it’s much too early to tell whether the latest BoJ innovations will be more successful, there is reason to be skeptical. No less important, the new approach involves risks to the central bank and to financial market stability that may not be fully appreciated. Given the difficulties that other advanced-economy central banks seem to be having in raising inflation and inflation expectations, how the BoJ fares is of interest far beyond Japan.

Policy and Measurement

Policy, especially monetary policy, is about numbers. Is inflation close to target? How fast is the economy growing? What fraction of the workforce is employed?  And, what is the relationship between the policymakers’ tools and their objectives? Answering all of these questions requires measuring a broad array of economic indicators, with consumer prices high on the list. In this post, we discuss some of the pitfalls in measuring prices.

Price indices of the sort that we use today have been around since the late 19th century. In the United States, near the end of World War I, the National Industrial Conference Board starting constructing and publishing a cost-of-living index. This work was eventually taken over by the Bureau of Labor Statistics (BLS). Over the past century, the theory of price indexes (see, for example, here and here) and the means of measurement have both moved forward substantially.

With the advent of inflation targeting, price indices have taken on a new prominence. If monetary policymakers are going to focus on controlling inflation—setting numerical targets for which they are then held accountable—then the construction of the price index itself becomes an issue. What is included and how can become critical to the way policy is conducted and to the achievement of the stated objective, namely price stability....

Rewriting the textbook: covered interest parity

For decades, textbooks on international economics and finance built a part of their scaffolding on the foundation of a relationship called covered interest parity (CIP). CIP postulates that, in a world of free capital flows, currency-hedged returns on equivalent-risk assets will equalize across countries. For example, the return to investing in a 1-year U.S. Treasury bill will equal the return to purchasing euros, investing the proceeds in a 1-year German Government liability, and purchasing a contract guaranteeing the future euro/dollar exchange rate at which the euros will be converted back to dollars a year later. In practice, the CIP relationship was such a reliable feature of international fixed-income markets that for decades one could think of banks operating a nearly costless CIP machine to perform what many viewed as a riskless arbitrage.

Then, one day, the CIP machine broke down. It first stopped working in the Great Financial Crisis (GFC) of 2007-2009, when counterparty and liquidity risks both skyrocketed, raising the possibility of defaults and losses in executing the trades necessary. That is, CIP was not a riskless arbitrage.

As a wave of recent research highlights, the conventional, pre-crisis model of the CIP machine remains impaired even as the counterparty and liquidity risks that characterized the GFC have receded....

Clinton versus Trump on Financial Regulation

Will the U.S. Presidential election have an impact on financial regulation? The answer depends on who becomes President, the priorities of the winner, and the inclinations of the Congress. That said, we thought it would be useful to examine what the candidates say they will do. To summarize, we find Republican nominee Trump’s call to “dismantle Dodd-Frank” deeply troubling. By comparison, our differences with Democratic nominee Clinton are relatively minor.

How risky are the big U.S. banks?

Readers of this blog know that we are great fans of the Stern Volatility Lab’s estimates of systemic risk. Like many observers, including leading regulators, we find market-value rather than book-value measures of bank equity more useful for timely monitoring of systemic risk created by individual intermediaries. Equity prices are available in real time, rapidly incorporate bank-specific and economy-wide information, and are forward-looking. This makes them particularly helpful in assessing the impact of big events, like this summer’s Brexit referendum (see our earlier post).

So, based as it is on market indicators of bank risk, not surprisingly we share the recent assessment of Sarin and Summers (expressed in their September 2016 Brookings paper) that the increase of book capital in the banking system since the financial crisis ought not give rise to regulatory complacency. We have argued repeatedly for raising capital requirements (see, for example, here) and, like those authors, believe that we need mechanisms for the virtually automatic recapitalization of banks in a crisis (see here).

Transparent stress tests?

This month, the Committee on Capital Market Regulation (CCMR) published a paper criticizing the procedures the Federal Reserve uses in conducting its stress tests. The claim is that, in its annual Comprehensive Capital Analysis and Review (CCAR), the Fed is violating the Administrative Procedures Act of 1946 (APA). The CCMR’s proposed solution is more transparency. As big fans of both stress tests and transparency in general, and of the CCAR in particular, we find this legal challenge very troubling.

We believe that making the stress tests more transparent in the ways that the CCMR suggests would make them much less effective. This would do serious damage to financial stability policy and (ultimately) increase the likelihood of another crisis...

Reforming mutual funds: a proposal to improve financial market resilience

U.S. capital markets are the deepest and broadest in the world, fortifying the country’s financial system and making its assets both liquid and attractive. A major part of this capital market advantage is due to the role played by mutual funds, which provide retail investors with a low-cost means of diversifying risk while earning a market return on their savings.

However, a growing class of mutual funds—those that hold mostly illiquid assets—appear to be a potential source of systemic risk. In this post we explain why, and then go on to suggest a change that is simple to implement and might mitigate the problem.
