Prattle provides sentiment data from central bank communications. I explored their Central Bank Sentiment Dataset, which contains weekly sentiment data from many central banks around the globe (though I focused on the Federal Reserve Bank). The sentiment data wraps up all publications of the Fed from every week (between about 1998 and 2015) into a score representing the market sentiment of the Fed that week.
In a previous notebook, I looked for relationships between Fed sentiment and prices of various macro-tracking ETFs. I follow up that investigation with this one, in which I construct a volatility metric for Fed sentiment, and look for relationships between Fed sentiment volatility and the volatilities of various macro-tracking ETFs. I found weak but nonetheless significant correlations, thus affirming the results of the previous notebook.
Please let me know if you have any interesting ideas regarding Fed sentiment that I should work on next!
