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?

Will Jeremy Corbyn stand down if Labour loses the general election?

Defeat at the polls might not be the end of Corbyn’s leadership.

The latest polls suggest that Labour is headed for heavy defeat in the June general election. Usually a general election loss would be the trigger for a leader to quit: Michael Foot, Gordon Brown and Ed Miliband all stood down after their first defeat, although Neil Kinnock saw out two losses before resigning in 1992.

It’s possible, if unlikely, that Corbyn could become prime minister. If that prospect doesn’t materialise, however, the question is: will Corbyn follow the majority of his predecessors and resign, or will he hang on in office?

Will Corbyn stand down? The rules

There is no formal process for the parliamentary Labour party to oust its leader, as it discovered in the 2016 leadership challenge. Even after a majority of his MPs had voted no confidence in him, Corbyn stayed on, ultimately winning his second leadership contest after it was decided that the current leader should be automatically included on the ballot.

This year’s conference will vote on to reform the leadership selection process that would make it easier for a left-wing candidate to get on the ballot (nicknamed the “McDonnell amendment” by centrists): Corbyn could be waiting for this motion to pass before he resigns.

Will Corbyn stand down? The membership

Corbyn’s support in the membership is still strong. Without an equally compelling candidate to put before the party, Corbyn’s opponents in the PLP are unlikely to initiate another leadership battle they’re likely to lose.

That said, a general election loss could change that. Polling from March suggests that half of Labour members wanted Corbyn to stand down either immediately or before the general election.

Will Corbyn stand down? The rumours

Sources close to Corbyn have said that he might not stand down, even if he leads Labour to a crushing defeat this June. They mention Kinnock’s survival after the 1987 general election as a precedent (although at the 1987 election, Labour did gain seats).

Will Corbyn stand down? The verdict

Given his struggles to manage his own MPs and the example of other leaders, it would be remarkable if Corbyn did not stand down should Labour lose the general election. However, staying on after a vote of no-confidence in 2016 was also remarkable, and the mooted changes to the leadership election process give him a reason to hold on until September in order to secure a left-wing succession.
