UBS' chief investment office said in a Wednesday report that a Federal Reserve communication review announced in June could be among the most consequential moves of the official leading it and may trigger a chain reaction in interest-rate market volatility.

UBS added the communication working group will include University of Washington professor Peter Fisher and former Bank of England official Mervyn King.
