Deposit insurance is a key regulatory tool for limiting bank runs and panics. In the United States, the Federal Deposit Insurance Corporation (FDIC) has insured bank deposits since 1934. FDIC-insured deposits are protected by a credible government guarantee, so there is little incentive to run.

However, deposit insurance creates moral hazard. By eliminating the incentive of depositors to monitor their banks, it encourages bank managers to rely on low-cost insured deposits to fund risky activities. In the extreme, with 100% deposit insurance coverage, banks would have virtually no incentive to issue equity or debt.

Against this background, and in light of the events of March-April 2023, we ask what is to be done about deposit insurance. To prevent bank runs, should there be an increase in the legal limit? If so, how can authorities balance the costs of runs and panics against the costs associated with moral hazard, while keeping in mind the potential financial burden on the public? Or, are there alternatives?

We emphasize three promising ways to enhance deposit insurance: a higher insurance cap for small and medium-sized enterprises (SMEs), new resolution rules, and the option to purchase supplementary deposit insurance. In addition, and as regular readers of this blog might expect, we also think that higher capital requirements should be part of the solution: if we require that banks increase the degree to which they finance their assets with capital (rather than deposits), the risk of runs and panics would decline even without raising the cap on deposit insurance….

SEC Money Market Fund Reform Proposals Fall Far Short, Again

As the principal regulator of U.S. money market mutual funds (MMMFs), the SEC has a duty to end the market distortions and moral hazard that repeated public rescues create. There have been two MMMF bailouts, so far. The first came at the height of the Great Financial Crisis of 2008, while the second followed in the March 2020 COVID crisis. While the Treasury provided guarantees only once, the Federal Reserve offered emergency liquidity assistance both times.

These repeated government interventions encourage MMMF managers to behave in ways that make future liquidity crises more likely. Moreover, there is no credible way for the Fed to promise not to intervene should a systemic disruption again loom in short-term funding markets. The only realistic means to end the subsidies created by the implicit promise of future bailouts is to force MMMFs to be far more resilient than they are today.

Against this background, the SEC’s December 2021 MMMF reform proposals are seriously disappointing. In this post, we start with basic facts about the scale and mix of MMMFs today. We then describe the SEC’s proposals, before focusing on their key shortcomings. We hope that the public comments that the SEC receives will motivate it, at the very least, to conduct a serious quantitative assessment of introducing capital requirements for the most vulnerable MMMFs, to re-assess the scale of additional liquid assets needed for MMMF resilience in the absence of a Fed backstop, and to propose ways to enhance the effectiveness and utility of MMMF stress tests….

Money Funds -- The Empire Strikes Back?

Shortly after Lehman failed in 2008, investors began to flee from money market mutual funds (MMMFs). To halt the run, the U.S. Treasury guaranteed all $3.8 trillion in outstanding MMMF liabilities. That rescue created enduring moral hazard: the expectation that a future crisis will lead to another bailout.

Aside from their legal form as mutual funds, MMMFs functioned much like banks engaged in the transformation of liquidity, credit and (to some extent) maturity. Similar to banks that redeem deposits at face value, they promised investors a fixed share value of $1 (a “buck”) on demand. Unlike depositories, however, MMMFs had no capital, no deposit insurance, and—at least officially—no access to the lender of last resort. So, when the Reserve Primary Fund “broke the buck” (by failing to redeem at the $1 par value) in September 2008, MMMF investors panicked.

Somewhat surprisingly, it took until 2014 for the Securities and Exchange Commission (SEC) to resolve political conflicts and introduce significant rule changes for MMMFs (see our earlier posts here and here). The SEC now requires that institutional prime MMMFs—which (like Reserve Primary) frequently invest in short-term corporate liabilities—operate like other mutual funds with a floating net asset value (NAV). The same rule applies to institutional municipal MMMFs. Retail MMMFs, as well as those investing in federal government (and agency) securities, are exempt.

In light of a recent legislative proposal to water it down, in this post we review the impact of the SEC’s 2014 reform. To highlight our conclusions: (1) it did not go far enough to reduce run risk; (2) aside from temporary dislocations, it has not raised nonfinancial sector funding costs by more than would be accounted for by reducing the implicit taxpayer guarantee for MMMFs; and (3) reversing the floating-NAV requirement would weaken the safety of the U.S. financial system....
