Stopping central banks from being prisoners of financial markets

Central banks are on the front lines in the fight to limit the impact of the pandemic. They are supporting virtually every aspect of the economy and the financial system. Combined with the massive fiscal support, these policies restored market stability, safeguarded financial institutions, and reduced suffering. Count us among those who firmly believe that everyone would be in worse shape had central banks and fiscal authorities not coordinated this aid as they did.

But, by providing such a broad backstop, the reliance of financial markets on that support can itself become a source of instability. This raises a set of very important and pressing questions: Have central banks’ actions over the past year made financial markets their masters? Can policymakers now be counted on to suppress financial volatility wherever it arises?

We surely hope not, but we see this as a legitimate concern. Fortunately, we also see a solution. Central bankers should strive to duplicate the success of their framework for interest rate policy. That is, they should be clear and transparent about their reaction function for all their policy tools. Knowing how policy will react, markets will respond directly to news regarding economic conditions, and less to policymakers’ commentary. Of course, central bankers cannot ignore shocks that threaten economic and price stability. But cushioning the economy against large financial disturbances does not mean minimizing market volatility….

Thoughts on Deposit Insurance

Government guarantees have become the norm in the financial system. According to the latest Federal Reserve Bank of Richmond (2017) estimate, the U.S. government’s safety net covers 60% of private financial liabilities in the United States. Serious underpricing of government guarantees gives intermediaries the incentive to take risk that can threaten the entire financial system: the Great Financial Crisis of 2007-09 is the most obvious case in point.

Deposit insurance is arguably the oldest and most widespread form of government guarantee in finance. In the United States, Congress established the Federal Deposit Insurance Corporation (FDIC) at the depth of the Great Depression in 1933 to help prevent bank runs. Today, more than 140 countries have some type of deposit insurance scheme.

In this post, we briefly review the evolution of FDIC deposit insurance pricing. We highlight evidence that, largely because of Congressional mandates, the federal insurance guarantee was underpriced for many years. It is not until 2011, following the crisis of 2007-09, that the FDIC introduced the current framework for risk-based deposit insurance fees, bringing insurance premia closer to what observers would deem to be actuarially fair.

Going forward, as with any insurance regime, keeping up with the evolution of bank (and broader financial system) risks will require a willingness to update the deposit insurance pricing framework from time to time. That means adjusting pricing to reflect both the range of bank risk-taking at a point in time and—to ensure the sustainability of the deposit insurance fund without taxpayer subsidies—the evolution of aggregate risk….

Limiting Central Banking

Since 2007, and especially over the past year, actions of public officials have blurred the lines between monetary and fiscal policy almost beyond recognition. Central banks have expanded both the scope and scale of their interventions in unprecedented fashion. This fiscalization risks central bank independence, thereby weakening policymakers’ ability to deliver on their mandates for price and financial stability. In our view, to find a way to back to the pre-2008 division of responsibilities, officials must establish clearer limits on what central banks can and cannot do.

In that division of official labor, it is fiscal authorities that ought to make the unavoidably political choices that directly influence resource allocation. And governments should not conceal such fiscal actions on the balance sheet of the central bank. In a democracy, doing so lacks legitimacy and would become unsustainable….

Is Inflation Coming?

For more than a generation, the U.S. inflation-targeting framework has delivered impressive results. From 1995 to 2007, U.S. inflation averaged 2.1% (as measured by the Federal Reserve’s preferred index). Since 2008, average inflation dropped to only 1.5%, but expectations have fluctuated in a narrow range: for example, the market-based five-year, five-year forward (CPI) inflation expectation rarely dipped below 1.5% and never exceeded 3%.

However, the pandemic brought with it many dramatic changes. Fiscal and monetary policy mobilized, responding swiftly to the economic plunge with a combination of extraordinary debt-financed expenditure and balance sheet expansion. As a matter of accounting and arithmetic, these actions have had a profound impact on the balance sheets of banks and households, spurring dramatic growth in traditional monetary aggregates. From the end of February to the end of May 2020, broad money (M2) grew from $15.5 trillion to $17.9 trillion—a 16% jump in just three months.

Won’t the record 2020 gain in M2 be highly inflationary? We doubt it, and in this post we explain why. At the same time, we highlight the chronic uncertainty that plagues inflation. In our view, the difficulty in forecasting inflation makes it important that the Fed routinely communicate how it will react to inflation surprises—even when, as now, policymakers wish to promote extremely accommodative financial conditions….

GameStop: Some Preliminary Lessons

Volatility in the stock market is not new. But, even if one takes a broad perspective, the recent experience with GameStop is extraordinary. As we write, the story is far from over, with several U.S. stocks—like GameStop, AMC Entertainment and Express—still on something of a wild ride. The Securities and Exchange Commission seems poised to investigate. And, members of Congress are planning to hold hearings. We don’t have any particular insights into how or when this will end. That is, except to say that history teaches us that episodes like this typically end badly.

Since this is an unusual post, we begin with a very clear disclaimer: nothing in this blog should be construed either as investment advice or legal advice.

In our view, we can already draw three big lessons from the equity market events of the past week. The first is about how narratives and the limits to arbitrage can lead to unsustainable asset price booms. Second, short sellers are important for the efficiency of asset pricing and the allocation of capital. Moreover, with the ongoing rise of passive index investing, their potential role in keeping the U.S. equity market efficient will become more, not less, salient. Third, to keep the financial system safe and resilient, it is essential that clearing firms maintain sufficiently stringent margin and collateral requirements even if, on occasion, it limits a broker’s ability to implement trades for its clients….

Open-end Funds vs. ETFs: Lessons from the COVID Stress Test

COVID-19 posed the most severe stress test for financial markets and institutions since the Great Financial Crisis (GFC) of 2007-09. By some measures, the COVID shock’s peak impact was larger than that of the GFC—both the VIX rose higher and intermediaries’ estimated capital shortfalls were bigger. As a result, the COVID experience provides a natural laboratory for testing the resilience of many parts of the post-GFC financial system.

For example, the March 2020 dysfunction in the corporate bond market highlights the extraordinary fragility of a market that accounts for nearly 60% of the debt and borrowings of the nonfinancial corporate sector. Yield spreads over equivalent Treasuries widened further than at any time since the GFC, with bond prices plunging even for instruments that have little risk of default. (See Liang for an excellent overview.)

In this post, we focus on how, because of the contractual agreement with their shareholders, an extraordinary wave of redemptions created selling pressure on corporate bond mutual funds that almost surely exacerbated the liquidity crisis in the corporate bond market. To foreshadow our conclusions, we urge policymakers to find ways to reduce the gap between the illiquidity of the assets held by corporate bond (and some other) mutual funds and the redemption-on-demand that these funds provide. To reduce systemic fragility, we also urge them—as we did several years ago—to consider encouraging conversion of mutual funds holding illiquid assets into ETFs, which suffered relatively less in the COVID crisis….

Fix Money Funds Now

On September 19, 2008, at the height of the financial crisis, the U.S. Treasury announced that it would guarantee the liabilities of money market mutual funds (MMMFs). And, the Federal Reserve created an emergency facility (“Asset-Backed Commercial Paper Money Market Mutual Fund Liquidity Facility”) to finance commercial banks’ purchases of illiquid MMMF assets. These policy actions halted the panic.

That episode drove home what we all knew: MMMFs are vulnerable to runs. Everyone also knew that the Treasury and Fed bailout created enormous moral hazard. Yet, the subsequent regulatory efforts to make MMMFs more resilient and less bank-like have proven to be half-hearted and, in some cases, counterproductive. So, to halt another run in March 2020, the Fed revived its 2008 emergency liquidity facilities.

We hope the second time’s the charm, and that U.S. policymakers will now act decisively to prevent yet another panic that would force yet another MMMF bailout.

In this post, we briefly review key regulatory changes affecting MMMFs over the past decade and their impact during the March 2020 crisis. We then discuss the options for MMMF reform that the President’s Working Group on Financial Markets identifies in their recent report. Our conclusion is that only two or three of the report’s 10 options would materially add to MMMF resilience. The fact that everyone has known about these for years highlights the political challenge of enacting credible reforms.

Big Tech, Fintech, and the Future of Credit

Lenders want to know that borrowers will pay them back. That means assessing creditworthiness before making a loan and then monitoring borrowers to ensure timely payment in full. Lenders have three principal tools for raising the likelihood of that firms will repay. First, they look for borrowers with a sufficiently large personal stake in their enterprise. Second, they look for firms with collateral that lenders can seize in the event of a default. Third, they obtain information on the firm’s current balance sheet, its historical revenue and profits, experience with past loans, and the like.

Unfortunately, this conventional approach to overcoming the challenges of asymmetric information is less effective for new firms that have both very short credit histories and very little in the way of physical collateral. As a result, these potential borrowers have trouble obtaining funds through standard channels. This is one reason that governments subsidize small business lending, and why entrepreneurs are forced to pledge their homes as collateral.

Well, new solutions have emerged to overcome this old problem. In this post we discuss how technology is increasing small firms’ access to credit. By using massive amounts of data to improve credit assessments, as well as real-time information and platform advantages to enforce repayment terms, technology companies appear to be doing what traditional lenders have not: making loans to millions of small businesses at attractive rates and experiencing remarkably low default rates.

The biggest advances are in places where financial systems are not meeting social needs….

Where Governments Should Spend More

As a result of the pandemic, U.S. general government debt (federal, state, and local obligations combined) has surged above 130 percent of GDP, more than double what it was in 2007. And, recent U.S. experience is far from unique. Looking at the G20, average public debt rose from 52% of GDP in 2007 to 74% in 2019 and is projected to reach 91% next year.

Unsurprisingly, as government debt increases, the debate over public spending heats up. Are these high debt ratios sustainable? Should we be cutting spending and raising taxes to reduce what will otherwise be a large financial burden on future generations?

In this post, we emphasize that not all government spending is created equal. Investment in physical infrastructure, as well as in education and health—especially for children—can boost future GDP. Moreover, delaying inevitable outlays can boost long-run costs. As a result, a failure to make productive, self-financing investments due to concerns about the debt would be not only tragic, but counterproductive….

What's in store for r*?

It is amazing how things we once thought impossible, or at least extremely improbable, can become commonplace. Ten-year government bond yields in most of Europe and Japan are at or below zero. And, for U.S. Treasurys, the yield has been below 1 percent since March.

A confluence of factors has come together to deliver these incredibly low interest rates. Most importantly, inflation is far lower and much more stable than it was 30 years ago. Second, monetary policy remains extremely accommodative, with policy rates stuck around zero (or below!) for the past decade in Europe and Japan, and only temporarily higher in the United States. Third, the equilibrium (or natural) real interest rate (r*)—the rate consistent in the longer run with stable inflation and full employment—has fallen by roughly 2 percentage points since 2008 and is now only 0.5% or lower.

How long will this go on? What’s in store for r*? Focusing on the United States, in this post we discuss the large post-2007 decline in r* that followed a gradual downward trend in prior decades. After considering various possible explanations, we focus on the change in U.S. saving behavior. Around 2008, there was an abrupt increase in household savings relative to wealth and income. Combined with increased foreign demand for U.S. assets, this appears to be a key culprit behind the recent fall in r*.

We doubt that this will change anytime soon….
