Ireland's Michael Conlan will have to pay a fine of CHF10,000 (£7,800/$9,700/€9,300) if he ever decides to re-register with a National Federation and return to Olympic boxing.
The bantamweight world champion went on an expletive-laden rant in a post-fight television interview after a controversial defeat at Rio 2016 in August.
Conlan, considered one of Ireland's best hopes for a medal in the sport, suffered a defeat in the quarter-final of the a under-56 kilograms category in the Brazilian city, despite appearing to dominate against Russian opponent Vladimir Nikitin.
He told Irish broadcaster RTE afterwards that the International Boxing Association (AIBA) were "cheats" and that amateur boxing "stinks from the core to the very top".
The Irishman vowed never to fight again for AIBA, whose President C K Wu then revealed that Conlan faced disciplinary action after he allegedly put his middle finger up at the judges following his loss.
AIBA have confirmed to insidethegames that the CHF10,000 fine has been awarded.
According to the Belfast Telegraph, the world governing body "reluctantly agree" that the fine, which is the maximum available to impose under its rules, may never be paid because Conlan has departed for the professional ranks.
The 25-year-old is due to make his professional debut on March 17 in 2017 to coincide with St Patrick's Day.
He has tweeted a picture with the caption: "You best give up now coz [sic] you a'int gon [sic] take my money".
If he wants to re-register with a National Federation or return as an amateur coach in the future, however, he will have to pay the fine before his application is considered by AIBA.
The three-person Disciplinary Commission reportedly accept that Conlan was "extremely distraught" after the bout, but still decided the fine was appropriate.
Nikitin later withdrew from his semi-final bout, but still claimed a bronze medal.
All 36 referees and judges used at Rio 2016 were suspended by AIBA until an investigation, which could lead to further reforms, has been concluded.
Changes have already been introduced to avoid similar problems in the future.
An independent Swiss Timing electronic draw system will now be used to select the judges for each bout, AIBA announced earlier this month, with the Draw Commission replaced by a single official overseeing this technology.
All five of their scorecards will be used to determine the winner, instead of just three.
Judges will also be placed on all four sides of the ring, while another change will see scores for each round only declared at the conclusion of a bout rather than at the ends of the rounds.
These changes are due come into operation at all tournaments in 2017.
Conlan was one of three boxers to receive a "severe reprimand" at Rio 2016 after he was found to have bet on matches.
