UPDATE 2-Hedge funds gained early access to BoE press conference feeds

The Bank of England (BoE) has admitted a rogue supplier has been misusing feeds of its press briefings, allowing high-speed traders access to market-sensitive information seconds before rivals.

Following a report in The Times newspaper, the central bank said on Wednesday a third-party supplier had accessed a back-up audio feed of some of its press conferences without consent and supplied it to "other external clients". Briefings by the BoE Governor Mark Carney and other top central bank officials often move markets including sterling and gilts, and access to them early would potentially allow traders to make millions.

News of the breach comes weeks before Carney is due to leave the BoE, with his replacement expected to be announced soon following last week's general election. The third-party supplier, whom the BoE did not name, had been misusing the audio feed since earlier this year, the central bank said in a statement.

"This wholly unacceptable use of the audio feed was without the Bank's knowledge or consent, and is being investigated further," it added. The audio feed was intended as a fallback option if the BoE's official video feed of the press conference went down, according to The Times.

Britain's Financial Conduct Authority, the body responsible for regulating markets and traders, did not immediately respond to a request for comment. The supplier in question had been sending the feed to high-speed traders who seek to benefit from receiving comments of the bank's governor before others can, according to The Times.

The BoE curbed the supplier's access once the misuse was identified to it by the newspaper and said that the supplier did not distribute feeds from its most recent press conference and will not be involved in any conferences in the future.
