Bank Systemic Risk Monitor - OFR Contagion Index

The OFR Bank Systemic Risk Monitor (BSRM) is a collection of key measures for monitoring systemic risks posed by the largest banks. These include systemic importance scores for international and U.S. banks, the OFR’s Contagion Index, and other common measures of systemic risk.

The monitor enhances and expands upon the OFR G-SIB Scores Interactive Chart.

The OFR’s Contagion Index measures the loss that could spill over to the rest of the financial system if a given bank were to default. It depends on the size of the bank, its leverage, and how connected it is to other financial institutions:

    OFR Contagion Index = Connectivity X Net Worth X (Outside Leverage - 1).

For foreign banks, the data presented are limited to the activities of the U.S. operations.

  • Year
  • Quarter
    • Q1
    • Q2
    • Q3
    • Q4



Data used in the calculation are obtained from the most recently reported values reported in the following Board of Governors of the Federal Reserve System’s reports: Consolidated Financial Statements for Holding Companies – FR Y-9C and Banking Organization Systemic Risk Report – FR Y-15. The quarterly values from those reports correspond to the selected year and quarter.

For analysis of the methodology, see OFR publications: How Likely is Contagion in Financial Networks?; Systemic Importance Indicators for 33 U.S. Bank Holding Companies: An Overview of Recent Data; and Contagion in Financial Networks.

Connectivity

Connectivity is measured as the share of the bank's unsecured liabilities that are held by other financial institutions. It is the ratio of the bank's liabilities within the financial system to the bank's total liabilities. With higher connectivity, a bank’s failure has a potentially broader impact on the rest of the financial system.

Net worth

Net worth, a measure of bank size, is the difference between a bank's assets and its liabilities. A larger bank's failure can have a broader impact on the financial system, other things being equal.

Outside leverage

Outside leverage captures the vulnerability of the bank to shocks from the real side of the economy. It is the ratio of a bank's claims on nonfinancial entities to its net worth.
