Abstract

We investigate whether dissent in monetary policy committees affect asset prices. We exploit a feature of the ECB communication for identification: the revelation of dissent during press conferences is separated from policy decision announcements. Following a narrative approach, we compute a novel granular index of ECB dissent for each instrument and identify the dissent direction. Using tick data, we isolate asset price changes exactly when dissent is revealed. Dissent has a strong negative effect on stock prices, that operates specifically around status quo decisions. Dissent is a key driver of stock prices on these days, explaining one-third of their variation.
