In recent years, U.S. banks have increasingly relied on deposits from financial intermediaries, especially money market funds (MMFs), which collect funds from large institutional investors and lend them to banks. In this paper, we show that intermediation through MMFs allows investors to limit...

We summarize and evaluate Fannie Mae and Freddie Mac's credit risk transfer (CRT) programs, which have been used since 2013 to shift a portion of credit risk on more than $1.8 trillion of mortgages to private sector investors. We argue that the CRT programs have been successful in reducing the...

Technology-based (“FinTech”) lenders increased their market share of U.S. mortgage lending from 2 percent to 8 percent from 2010 to 2016. Using market-wide, loan-level data on U.S. mortgage applications and originations, we show that FinTech lenders process mortgage applications about 20...

Savers with uncertain life spans cannot stick to long-term investment plans when they invest directly in liquid assets. Before horizons are known, all savers will plan to roll over their short-term assets if returns turn out high. Ex post, the short-term investors will consume their liquid...

We identify and track over time the factors that make the financial system vulnerable to fire sales by constructing an index of aggregate vulnerability. The index starts increasing quickly in 2004, before most other major systemic risk measures, and triples by 2008. The fire-sale-specific...

We argue that post-crisis banking regulations pass through from regulated institutions to unregulated arbitrageurs. We document that, once post-crisis regulations bind post 2014, hedge funds use a larger number of prime brokers and diversify away from GSIB-affiliated prime brokers, and that the...

We build a model of a financial intermediary, in the tradition of Diamond and Dybvig (1983), and show that allowing the intermediary to impose redemption fees or gates in a crisis — a form of suspension of convertibility — can lead to preemptive runs. In our model, a fraction of investors...

We review recent changes in monetary policy that have led to development and testing of an overnight reverse repurchase agreement (ON RRP) facility, an innovative tool for implementing monetary policy during the normalization process. Making ON RRPs available to a broad set of investors,...

Bank capital requirements are based on a mix of market values and book values. We investigate the effects of a policy change that ties regulatory capital to the market value of the "available-for-sale" investment securities portfolio for some banking organizations. Our analysis is based on...
