The index is estimated on unstructured data from 1,400 Telegram channels. This is the first index of its kind, providing a comprehensive picture of the information field by classifying channels into types and key areas of the Bank of Russia's activities, from monetary policy to the financial market and the national payment system. For text analysis, we use both the traditional dictionary method and modern large linguistic models. The final index correlates with household inflation expectations and business price expectations but has no statistical link to financial market variables. The index opens up new opportunities for researching public perception of the Bank of Russia's policy and can be used as a tool for assessing the effectiveness of its communication.
