Do supervisory examinations of large commercial banking firms produce usefu
l information not already reflected in market prices? To investigate this q
uestion, we apply a new research methodology to data on bank exam ratings a
nd the subordinated debt risk spreads of their parent holding companies. We
find that government exams do produce new, value-relevant information; tha
t debenture prices do not immediately reflect this information; and that th
e market prices the likely regulatory actions implied by this information.
These results have implications for market versus regulatory discipline at
large banking firms, and for proposals to make subordinated debt mandatory
for these firms.
