In general, when central banks target a short-term interest rate, this aspect of transparency is reasonably easy to implement because an interest rate is easy for financial market participants, members of the legislature, and the general public alike to understand.
But transparency may be more difficult to achieve when the central bank employs other operating targets, such as the reserve targets that the Federal Reserve used in the early 1980s. Changes in such targets could often reflect technical developments and not changes in the desired policy stance.
