Ten Precepts for 21st Century Regulators

The regulatory reforms that followed the financial crisis of 2007-09 created a financial system that is far more resilient than the one in place 15 years ago. Yet, the events of March 2023 make clear that the progress thus far is simply not enough. To ensure resilience, we need to do more.

To steer the process of further reform, we propose a set of 10 precepts that those who make the rules should keep in mind as they refine the prudential framework. These practical guidelines lead us to conclusions that mirror those in a recent post: regulation should be more rule-based (less reliant on supervisory insight or discretion); simpler and more transparent; stricter and more rigorous; and more efficient in its use of resources. Concretely, this approach means increasing capital and liquidity requirements; shifting to mark-to-market accounting; and improving the transparency, flexibility and severity of capital and liquidity stress tests.

Reforming the Federal Home Loan Bank System

We authored this post jointly with our friend and colleague, Lawrence J. White, Robert Kavesh Professor of Economics at the NYU Stern School of Business.

Some government financial institutions strengthen the system; others do not. In the United States, as the lender of last resort (LOLR), the Federal Reserve plays a critical role in stabilizing the financial system. Unfortunately, their LOLR job is made harder by the presence of the Federal Home Loan Bank (FHLB) system—a government-sponsored enterprise (GSE) that acts as a lender of next-to-last resort, keeping failing institutions alive and increasing the ultimate costs of their resolution.

We saw this dangerous pattern clearly over the past year when loans (“advances”) from Federal Home Loan Banks (FHLBs) helped postpone the inevitable regulatory reckoning for Silicon Valley Bank (SVB), Signature Bank, and First Republic Bank (see Cecchetti, Schoenholtz and White, Chapter 9 in Acharya et. al. SVB and Beyond: The Banking Stress of 2023).

From a public policy perspective, FHLB advances have extremely undesirable properties. First, in addition to being overcollateralized, these loans are senior to other claims on the borrowing banks—including those of the Federal Deposit Insurance Corporation (FDIC) and the Federal Reserve: If the borrower defaults, the FHLB lender has a “super-lien.” Second, there is little timely disclosure about the identity of the borrowers or the amount that they borrow. Third, they are willing to provide speedy, low-cost funding to failing institutions—something we assume private lenders would not do.

In this post, we make specific proposals to scale back the FHLB System’s ability to serve as a lender to stressed banks….

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.

Cyber Risk, Financial Stability and the Payments System

Cyber risk remains at the top of the list of risks to the financial system, and the financial system is well known as the primary target for hackers (see here, here and here). In response, financial institutions expend huge resources on protecting their information systems—by one estimate, well over $100 billion. Yet, private sector actions to prevent cyber losses fall short due to a glaring externality: since the damage is likely to spill over to other financial firms and to markets, individual firms cannot reap the full benefits of preventing cyber attacks.

To get a sense of the financial stability risks associated with cyber fragility, we need to understand the financial system in some detail. Unfortunately, financial networks are highly complex and vary significantly across markets and functions. They also evolve meaningfully over time. On top of these enormous challenges, assessing network vulnerabilities frequently requires institution- or transactions-level information that is normally not publicly available.

This brings us to the important recent work of Eisenbach, Kovner and Lee (EKL), who study the vulnerability of the U.S. large-value interbank payments system, Fedwire, to a cyber attack on one of the principal nodes of the payments network—namely, one of the top five banks. In this post, we highlight EKL’s analysis as a model for the assessment of cyber-driven network risks. We suggest how central bankers should react to a cyber attack on the payments system, and speculate about what is needed to prevent, as well as mitigate, cyber risks….

Ninth Anniversary of the GSEs' Conservatorships: Not a Time to Celebrate

In the summer of 2008, Fannie Mae and Freddie Mac’s financial positions deteriorated sharply: the result of inadequate capital (equity financing) for the risks in the residential mortgages that they held and had securitized. On September 6, 2008, their regulator, the Federal Housing Finance Agency (FHFA), removed senior management and placed these government-sponsored enterprises (GSEs) into conservatorships. Since then, the FHFA and the U.S. Treasury (which extended almost $188 billion to keep them solvent through 2011) have run them...

Modernizing the U.S. Payments System: Faster, Cheaper, and more Secure

When it comes to domestic payments, the U.S. financial system still lags the efficiency in several advanced economies. The reasons are easy to find. First, other countries have leapfrogged outdated technologies. In the United States, checks remained dominant well after their technological sell-by date partly as a result of government support. The other key factor delaying a shift to alternative payment mechanisms is the importance of what economists call a network externality. That is, the more people who use one form of payment, the more valuable that method is to the people who are already using it. And, by the same token, the more expensive it is for someone to move away from the prevailing mechanism.

With these considerations in mind, two years ago the Fed convened the Faster Payments Task Force (FPTF), a group of more than 300 experts and interested parties from a wide range of backgrounds with the objective to “identify and evaluate alternative approaches for implementing safe, ubiquitous, faster payments capabilities in the United States.” Earlier this month, the FPTF issued its second and final report, which contains a set of 10 recommendations for making the payments system faster, cheaper and more secure....
