A Robin Hood Tax will stop the machines wiping out the market

A small tax on each transaction will stop pointless yet risky high-frequency trading.

From Terminator to the Matrix, our fear that humanity may be supplanted by the machines we create has helped Hollywood make mega-bucks. But while Arnie’s cyborg killing machine and the Neo’s alternative reality remain firmly in the realms of science fiction, our financial sector’s love of a fast buck is leading us to cede control of markets to computers with sometimes disastrous consequences.

The extent to which financial markets are now dominated by computer-driven high frequency trading was revealed again last week, when Knight Capital, a leading New York trading firm made a mistake in its computer programming. The rogue programme swamped the stock market with errant trades, cost the firm $440 million and put the future of the firm in jeopardy.

So what? I hear you ask. Why should we care if a firm of traders loses millions because they rushed out a new computer programme before it was ready?

The fact is that beyond acting as a casino for traders to make or lose fortunes, financial markets are crucial to the functioning of the global economy. They are supposed to allocate resources efficiently and help firms raise capital and manage risk. When things go wrong, as in the crisis of 2008, the consequences for the real economy can be devastating.

A growing number of economists and financial experts – including more than 50 financiers who wrote a recent letter to David Cameron and other world leaders – are warning that unchecked high-frequency trading undermines markets’ economic efficiency and risks disaster. In May 2010, the most infamous "flash crash" dragged the Dow Jones index of shares down nine per cent with more than half the fall happening in just seven minutes. Shares in Accenture plunged from $40 per share to just $0.01, almost wiping out the value of the company.

High frequency trading (HFT) conducted may now account for more than three-quarters of all equity deals in the UK. When you consider that this sort of trading, managed by computers according to complex algorithms, was almost unheard of seven years ago, it is hard to avoid the conclusion that traders have been competing in a technological arms race that has left regulators floundering.

So what can be done? As anti-nuclear campaigners have discovered, it is not possible to un-invent a technology once the genie has left the bottle. But fortunately this is not necessary. High-frequency trading is only profitable because of the sheer volume of trades carried out; the profit margin on each trade is incredibly low.

A tiny tax of a fraction of a percent on each transaction would curb the worst excesses of this cyborg-style casino capitalism, while having little effect on long-term investments such as pensions where trades are carried out far less frequently.

European leaders are working towards such a tax – covering stocks, bonds and derivatives – but the UK government has chosen to side with City interests rather than back the efforts of Germany, France, Spain, Italy and others to make finance work in the interests of society rather than the other way around.

UK opposition to the tax, based as it is on the claim that such taxes have to be global to work, is somewhat ironic. The UK already has an FTT on shares, known as the Stamp Duty, which at 0.5 per cent is many times larger than the proposed European tax (0.1 per cent for shares and bonds, 0.01 per cent for derivatives). The problem is that banks, hedge funds and other high-frequency traders avoid the stamp duty by trading in derivatives.

Extending the UK’s existing FTT to derivatives and bonds would not only "throw sand in the wheels" of HFT and therefore increase stability in financial markets and the wider-economy; it would also raise billions in revenue – the reason the Robin Hood tax campaign is backed by almost 120 organisations from Oxfam to the TUC and by global figures such as Kofi Annan and Bill Gates.

Despite avoidance, the UK Stamp Duty raise £3bn a year. A full-blown FTT could raise as much as £20bn – money that could be used to help those hit by the economic crisis at home and abroad and to meet the UK’s obligations to help poor countries cope with climate change.

It can be done. The UK’s Stamp Duty is one of 40 or so FTTs that already exist around the world. Hong Kong has introduced an FTT on derivatives precisely to curb the excess of computer-driven trading. Charles Li, Chief Executive of the Hong Kong Stock Exchange, says it "effectively limits high frequency trading, just like a highway with many toll booths limits speeding."

By rejecting a broader FTT, the UK government is making its own bet on the markets. It is accepting instability and forgoing much needed revenue in the hope the City’s casino capitalism will help drive recovery from recession.

It is a risky bet. As Andrew Haldane, Executive Director of Financial Stability at the Bank of England has put it:

"Grit in the wheels, like grit on the roads, could help forestall the next crash."

"Whoa" ~ Neo, The Matrix. Do we all fear that machines will supplant us?

Ken Livingstone says publicly what many are saying privately: tomorrow belongs to John McDonnell

The Shadow Chancellor has emerged as a frontrunner should another Labour leadership election happen. 

“It would be John.” Ken Livingstone, one of Jeremy Corbyn’s most vocal allies in the media, has said publicly what many are saying privately: if something does happen to Corbyn, or should he choose to step down, place your bets on John McDonnell. Livingstone, speaking to Russia Today, said that if Corbyn were "pushed under a bus", John McDonnell, the shadow chancellor, would be the preferred candidate to replace him.

Even among the Labour leader’s allies, speculation is rife as to if the Islington North MP will lead the party into the 2020 election. Corbyn would be 71 in 2020 – the oldest candidate for Prime Minister since Clement Attlee lost the 1955 election aged 72.

While Corbyn is said to be enjoying the role at present, he still resents the intrusion of much of the press and dislikes many of the duties of the party leader. McDonnell, however, has impressed even some critics with his increasingly polished TV performances and has wowed a few sceptical donors. One big donor, who was thinking of pulling their money, confided that a one-on-one chat with the shadow chancellor had left them feeling much happier than a similar chat with Ed Miliband.

The issue of the succession is widely discussed on the left. For many, having waited decades to achieve a position of power, pinning their hopes on the health of one man would be unforgivably foolish. One historically-minded trade union official points out that Hugh Gaitskell, at 56, and John Smith, at 55, were 10 and 11 years younger than Corbyn when they died. In 1994, the right was ready and had two natural successors in the shape of Tony Blair and Gordon Brown in place. In 1963, the right was unprepared and lost the leadership to Harold Wilson, from the party's centre. "If something happens, or he just decides to call it a day, [we have to make sure] it will be '94 not '63," they observed.

While McDonnell is just two years younger than Corbyn, his closest ally in politics and a close personal friend, he is seen by some as considerably more vigorous. His increasingly frequent outings on television have seen him emerge as one of the most adept media performers from the Labour left, and he has won internal plaudits for his recent tussles with George Osborne over the tax bill.

The left’s hopes of securing a non-Corbyn candidate on the ballot have been boosted in recent weeks. The parliamentary Labour party’s successful attempt to boot Steve Rotheram off the party’s ruling NEC, while superficially a victory for the party’s Corbynsceptics, revealed that the numbers are still there for a candidate of the left to make the ballot. 30 MPs voted to keep Rotheram in place, with many MPs from the left of the party, including McDonnell, Corbyn, Diane Abbott and John Trickett, abstaining.

The ballot threshold has risen due to a little-noticed rule change, agreed over the summer, to give members of the European Parliament equal rights with members of the Westminster Parliament. However, Labour’s MEPs are more leftwing, on the whole, than the party in Westminster . In addition, party members vote on the order that Labour MEPs appear on the party list, increasing (or decreasing) their chances of being re-elected, making them more likely to be susceptible to an organised campaign to secure a place for a leftwinger on the ballot.

That makes it – in the views of many key players – incredibly likely that the necessary 51 nominations to secure a place on the ballot are well within reach for the left, particularly if by-election selections in Ogmore, where the sitting MP, is standing down to run for the Welsh Assembly, and Sheffield Brightside, where Harry Harpham has died, return candidates from the party’s left.

McDonnell’s rivals on the left of the party are believed to have fallen short for one reason or another. Clive Lewis, who many party activists believe could provide Corbynism without the historical baggage of the man himself, is unlikely to be able to secure the nominations necessary to make the ballot.

Any left candidate’s route to the ballot paper runs through the 2015 intake, who are on the whole more leftwing than their predecessors. But Lewis has alienated many of his potential allies, with his antics in the 2015 intake’s WhatsApp group a sore point for many. “He has brought too much politics into it,” complained one MP who is also on the left of the party. (The group is usually used for blowing off steam and arranging social events.)

Lisa Nandy, who is from the soft left rather than the left of the party, is widely believed to be in the running also, despite her ruling out any leadership ambitions in a recent interview with the New Statesman.However, she would represent a break from the Corbynite approach, albeit a more leftwing one than Dan Jarvis or Hilary Benn.

Local party chairs in no doubt that the shadow chancellor is profiling should another leadership election arise. One constituency chair noted to the New Statesman that: “you could tell who was going for it [last time], because they were desperate to speak [at events]”. Tom Watson, Caroline Flint, Chuka Umunna, Yvette Cooper, Andy Burnham and Liz Kendall all visited local parties across the country in preparation for their election bids in 2015.

Now, speaking to local party activists, four names are mentioned more than any other: Dan Jarvis, currently on the backbenches, but in whom the hopes – and the donations – of many who are disillusioned by the current leadership are invested, Gloria De Piero, who is touring the country as part of the party’s voter registration drive, her close ally Jon Ashworth, and John McDonnell.

Another close ally of Corbyn and McDonnell, who worked closely on the leadership election, is in no doubt that the shadow chancellor is gearing up for a run should the need arise.  “You remember when that nice Mr Watson went touring the country? Well, pay attention to John’s movements.”

As for his chances of success, McDonnell may well be even more popular among members than Corbyn himself. He is regularly at or near the top of LabourList's shadow cabinet rankings, and is frequently praised by members. Should he be able to secure the nominations to get on the ballot, an even bigger victory than that secured by Corbyn in September is not out of the question.
