The Reserve Bank of India (RBI) has prevented their officials who are attending official or unofficial meetings to speak to the media. They are also not allowed to speak of the position that they hold in order to prevent leaks.
This is the first time a formal notice has been given to the officials preventing them from interacting with the press. RBI is concerned that whatever the officials express as their own opinion would be considered the opinion of RBI as a whole.
This seems to have been the result of the news report saying that RBI is planning to withdraw old 100, 10, and 5 rupee notes. RBI issued a circular reporting the news as false. Senior members of the RBI regularly attend formal or informal meetings at the regional level.
