Bloomberg caught peeking at Goldman Sachs' data

The company will restrict access its journalists have to customer information.

Bloomberg is hastily changing its data-access policies after a journalist working for its news service accidentally revealed that they had access to potentially sensitive information, according to a report in the New York Post:

Irked Goldman Sachs brass recently confronted Bloomberg LP over concerns reporters at the business news service have been using the company’s ubiquitous terminals to keep tabs on some employees of the Wall Street bank, The Post has learned.

The ability to snoop on Bloomberg terminal users came to light recently when Goldman officials learned that at least one reporter at the news service had access to a wide array of information about customer usage, sources said.

In one instance, a Bloomberg reporter asked a Goldman executive if a partner at the bank had recently left the firm — noting casually that he hadn’t logged into his Bloomberg terminal in some time, sources added.

Goldman later learned that Bloomberg staffers could determine not only which of its employees had logged into Bloomberg’s proprietary terminals but how many times they had used particular functions, insiders said.

Bloomberg confirmed that "limited customer relationship data" has been available to the company's reporters for some time, although it has never included "clients’ security-level data, position data, trading data or messages". It has now removed access to the customer information for all its journalists.

The news could be extremely damaging for the company and its billionaire owner New York mayor Michael Bloomberg. The bedrock of his fortune is built on the company's proprietary terminals, which are rented out to financial firms for over £10,000 a year each and provide huge quantities of real-time information on subjects from financial news to sports results. Although Bloomberg has competitors, like Thompson Reuters, there are few which provide quite the same service, allowing it to maintain its monopoly pricing and, er, charmingly idiosyncratic user interface.

If customers start to believe it can't be trusted with the incredibly sensitive data that goes through it all the time, that business could start draining away – which would be one of the biggest shake-ups to hit the financial sector since 2008.

Why the Labour rebels have delayed their leadership challenge

MPs hope that Jeremy Corbyn may yet resign, while Owen Smith is competing with Angela Eagle to be the candidate.

The Eagle has hovered but not yet landed. Yesterday evening Angela Eagle's team briefed that she would launch her leadership challenge at 3pm today. A senior MP told me: "the overwhelming view of the PLP is that she is the one to unite Labour." But by this lunchtime it had become clear that Eagle wouldn't declare today.

The delay is partly due to the hope that Jeremy Corbyn may yet be persuaded to resign. Four members of his shadow cabinet - Clive Lewis, Rachel Maskell, Cat Smith and Andy McDonald - were said by sources to want the Labour leader to stand down. When they denied that this was the case, I was told: "Then they're lying to their colleagues". There is also increasing speculation that Corbyn has come close to departing. "JC was five minutes away from resigning yesterday," an insider said. "But Seumas [Milne] torpedoed the discussions he was having with Tom Watson." 

Some speak of a potential deal under which Corbyn would resign in return for a guarantee that an ally, such as John McDonnell or Lewis, would make the ballot. But others say there is not now, never has there ever been, any prospect of Corbyn departing. "The obligation he feels to his supporters is what sustains him," a senior ally told me. Corbyn's supporters, who are confident they can win a new leadership contest, were cheered by Eagle's delay. "The fact even Angela isn't sure she should be leader is telling, JC hasn't wavered once," a source said. But her supporters say she is merely waiting for him to "do the decent thing". 

Another reason for the postponement is a rival bid by Owen Smith. Like Eagle, the former shadow work and pensions secrtary is said to have collected the 51 MP/MEP nominations required to stand. Smith, who first revealed his leadership ambitions to me in an interview in January, is regarded by some as the stronger candidate. His supporters fear that Eagle's votes in favour of the Iraq war and Syria air strikes (which Smith opposed) would be fatal to her bid. 

On one point Labour MPs are agreed: there must be just one "unity candidate". But after today's delay, a challenger may not be agreed until Monday. In the meantime, the rebels' faint hope that Corbyn may depart endures.
