Abstract

We compare news in Twitter with traditional news outlets and emphasize their differential impact on Eurozone’s sovereign bond market. We reveal a two-way information flow between Twitter’s Grexit tweets and Grexit mentions in traditional news which suggests not only that both types of news serve as important empirical predictors for the sovereign bond market but also that the old (traditional news) and the new (Twitter) media are connected; however, the influence of Twitter on traditional news is stronger. Grexit tweets raise the Greek spread more than Grexit mentions in traditional news. Weak contagion effects are recorded for Portugal and Ireland.
