No never. You cant leak what is already known to EVERYONE (but you)
Everyone knows the Fed will raise rates by 0.25. The Fed tends to suggest where the rates will go long in advance as study of the Fed Funds or Eurodollar futures will show. Too much is at stake to shock the market with anything else - last time they tried that stunt there was a crash (87 I think)
In my experience, when the number is released, there is a lot of volatility, but little net change by the time of the close.
IMO volatility is small before the release because it is the main event of the day and markets tend to have already priced in the change so there is little else to move the market.
Speculators tend to analysis how things were said rather than what was said. FOMC minutes are often better moves for the speculate opportunity.
Never say never.
