Broad was found to have breached Article 2.1.7 of the ICC Code of Conduct for Players and Player Support Personnel, which relates to "public criticism of, or inappropriate comment in relation to an incident occurring in an International Match or any Player, Player Support Personnel, Match official or team participating in any International Match", ICC said in a media release on Sunday.
Reacting to the penalty, Broad tweeted "Shame to be fined. Back to bland and unopinionated press conferences I'm afraid. Draw a line onto the next game!."
On Sunday evening, Broad admitted the offence and accepted the proposed sanction offered to him by Javagal Srinath of the Emirates Elite Panel of ICC Match Referees.
The charge related to comments made by Broad following his side's loss to New Zealand in a match reduced by rain (Duckworth-Lewis Method).
Explaining his decision, Srinath said: "Umpires are the final judges of the fitness of the ground, weather or light for play. Weather decisions are the most difficult to make, but the umpires make the best decision possible, taking all factors into account. Such public criticism is not good for the spirit of the game. Mutual respect between players, match officials and administrators is paramount to the game of cricket."
The charge was laid by on-field umpires Paul Reiffel and Aleem Dar, third umpire Rod Tucker and fourth umpire S. Ravi.
The range of permissible sanctions for all first Level 1 offences is a warning or reprimand and/or the imposition of a fine of up to 50 per cent of the applicable match fee.
