A Map of Funding Durability and Risk

The dynamics of the financial system and the undercurrents of its vulnerabilities rest on the flow of funding. Analysts typically represent these dynamics as a network with banks and financial entities as the nodes and the funding links as the edges. This paper focuses instead on the funding operations within the nodes, in particular those within Bank/Dealers, adding a critical level of detail about potential funding risks. We present a funding map to illustrate the primary business activities and funding sources of a typical Bank/Dealer. We use that map to trace the paths of risk through four specific financial institutions during historical crises and to identify gaps in data needed for financial stability monitoring. We also introduce the concept of "funding durability," defined as the effective term of funding in the face of signaling and reputational considerations during periods of stress. Using these tools, the paper highlights the points of potential durability mismatch and resulting funding risks within the Bank/Dealer. It also provides insight into how funding weaknesses can pass from one institution to another and ultimately affect financial stability.
