Interest Rates and Derivatives Exposures Drive Banks’ Systemic Risk<br />

Indicators<br />

The <strong>OFR</strong> analyzed what may be driving systemic risk for<br />

large U.S. banks. The results show a flatter yield curve and<br />

higher derivatives exposures are associated with greater<br />

systemic risk. The results also highlight the difficulty of<br />

quantifying risks associated with particular noncommercial-banking<br />

activities using public data.<br />

The analysis considered 19 U.S. bank holding companies<br />

with consolidated assets of $50 billion or more. The<br />

goal was to identify drivers of two systemic risk indicators:<br />

Conditional Value-at-Risk (CoVaR) and SRISK (see Systemic<br />

Risk Metrics in Section 2.5). CoVaR was calculated internally.<br />

SRISK was obtained from New York University. Each<br />

indicator was measured monthly by firm and then aggregated<br />

on a quarterly basis from the first quarter of 2010<br />

through the first quarter of <strong>2016</strong>.<br />

The five performance variables investigated as potential<br />

drivers of large banks’ systemic risk were in three categories:<br />

(1) slope of the Treasury curve (the yield spread<br />

between 10-year and 1-year Treasuries); (2) complexity<br />

and interconnectedness (a bank’s total gross notional<br />

derivatives exposure relative to total consolidated assets);<br />

and (3) business structure (fiduciary income, brokerage<br />

activities income, and investment banking income relative<br />

to pretax operating income).<br />

At a 5 percent level, the first two of the five variables were<br />

found to be statistically significant drivers of CoVaR and<br />

SRISK — an increase in a bank’s derivatives exposure and<br />

a flatter Treasury curve (see Figure 62). The Treasury curve<br />

is related to earnings risk because it proxies for banks’<br />

opportunity to generate net income from the spread<br />

between interest earned on loans and interest paid on<br />

deposits. Its significance as a driver of systemic risk highlights<br />

banks’ earnings challenges when long-term interest<br />

rates are low.<br />

The business structure variables studied did not prove<br />

to be drivers of either of the two systemic risk indicators.<br />

These volume-based measures of noncommercial-bank<br />

business activity likely did not capture the associated risk<br />

profiles. Also, derivatives exposure may have already captured<br />

some business structure-related risks.<br />
