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 />
