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."

The buck doesn't stop with Grant Shapps - and probably shouldn't stop with Lord Feldman, either

The question of "who knew what, and when?" shouldn't stop with the Conservative peer.

If Grant Shapps’ enforced resignation as a minister was intended to draw a line under the Mark Clarke affair, it has had the reverse effect. Attention is now shifting to Lord Feldman, who was joint chair during Shapps’  tenure at the top of CCHQ.  It is not just the allegations of sexual harrassment, bullying, and extortion against Mark Clarke, but the question of who knew what, and when.

Although Shapps’ resignation letter says that “the buck” stops with him, his allies are privately furious at his de facto sacking, and they are pointing the finger at Feldman. They point out that not only was Feldman the senior partner on paper, but when the rewards for the unexpected election victory were handed out, it was Feldman who was held up as the key man, while Shapps was given what they see as a relatively lowly position in the Department for International Development.  Yet Feldman is still in post while Shapps was effectively forced out by David Cameron. Once again, says one, “the PM’s mates are protected, the rest of us shafted”.

As Simon Walters reports in this morning’s Mail on Sunday, the focus is turning onto Feldman, while Paul Goodman, the editor of the influential grassroots website ConservativeHome has piled further pressure on the peer by calling for him to go.

But even Feldman’s resignation is unlikely to be the end of the matter. Although the scope of the allegations against Clarke were unknown to many, questions about his behaviour were widespread, and fears about the conduct of elections in the party’s youth wing are also longstanding. Shortly after the 2010 election, Conservative student activists told me they’d cheered when Sadiq Khan defeated Clarke in Tooting, while a group of Conservative staffers were said to be part of the “Six per cent club” – they wanted a swing big enough for a Tory majority, but too small for Clarke to win his seat. The viciousness of Conservative Future’s internal elections is sufficiently well-known, meanwhile, to be a repeated refrain among defenders of the notoriously opaque democratic process in Labour Students, with supporters of a one member one vote system asked if they would risk elections as vicious as those in their Tory equivalent.

Just as it seems unlikely that Feldman remained ignorant of allegations against Clarke if Shapps knew, it feels untenable to argue that Clarke’s defeat could be cheered by both student Conservatives and Tory staffers and the unpleasantness of the party’s internal election sufficiently well-known by its opponents, without coming across the desk of Conservative politicians above even the chair of CCHQ’s paygrade.
