Non-bank financial institutions (NBFIs) have grown steadily over the last two decades, becoming important providers of financial intermediation services. As NBFIs naturally interact with banking institutions in many markets and provide a wide range of services, banks may develop significant direct exposures stemming from these counterparty relationships. However, banks may be also exposed to NBFIs indirectly, simply by virtue of commonality in asset holdings. This post and its companion piece focus on this indirect form of exposure and propose ways to identify and quantify such vulnerabilities.
In a Liberty Street Economics post that appeared yesterday, we described the mechanics of the Federal Reserve’s balance sheet “runoff” when newly issued Treasury securities are purchased by banks and money market funds (MMFs). The same mechanics would largely hold true when mortgage-backed securities (MBS) are purchased by banks. In this post, we show what happens when newly issued Treasury securities are purchased by levered nonbank financial institutions (NBFIs)—such as hedge funds or nonbank dealers—and by households.
