Central bankers all over the world are not exactly known for clarity in their language. Nevertheless, the rational expectations school in macroeconomics holds that no policy can be successful over a period by “fooling” the economic agents. In this context, one may differentiate between genuine uncertainties about the future vis-à-vis not revealing the expected outcome of the policy.
In this respect, it may be noted that banking supervision and regulation are naturally frequently re-assessed in light of new developments.
