Foreign exchange platform puts the brakes on high-frequency traders

EBS has changed its rules to discourage algobots.

EBS, a major interbank trading platform in in the foreign exchange market, is considering imposing a major change in the way it runs its market in order to discourage high-frequency trading from taking place.

EBS currently runs on the principle of "first in, first out" trading, where trades are dealt with in the exact order they are made. That is the way most people expect the market to work – but it also gives an advantage to those who can get their trades in quickest. That leads to the arms race that high-frequency trading has seen in the last few years, where traders pay to place their servers close to the exchange, to whittle off those last few microseconds.

Instead of this model, EBS is considering bundling together incoming trades and dealing with them in a random order. That way, every trade that came in in (for example) the tenth of a second between 12:00:00.0 and 12:00:00.1 would be grouped together and dealt in a random order, removing the advantage that the trader who got in at 12:00:00.01 would normally have.

Speaking to the FT, the chief executive of EBS explained why the company has made the decision:

The first twenty years of algorithmic trading have added great transparency and led to the compression of spreads – all great things. But there is a line beyond which marginal speed and smaller trade sizes add no value and actually harm the markets. At some point we, the public markets across asset classes, crossed that line.

The ‘first in, first out’ model sounds fair and plausible, but in modern public markets it implies ‘winner takes all’.

The classic example of how high(er)-frequency trading can have positive effects comes from the fact that the desire to shave seconds off the response time to financial information is the reason why the undersea cables linking London to New York are so high quality. Without that motivation to profit, the cables might not have been laid for decades after, and certainly wouldn't be as fast as they are now. (In fact, the USD/GBP exchange rate is still known as "cable" now, after the first transatlantic cable laid in 1858).

But as the speed of trades has increased ever higher, the side-benefits are shrinking. The difference in liquidity between a market where a tenth of a second and a thousandth of a second matters is minuscule; even if spreads might be a tiny bit tighter than they otherwise would be, no normal trader is helped by that "improvement".

So EBS's speed limit is a welcome step. By dealing with trades in a semi-random order, it removes the incentive to spend millions on shaving off the smallest fractions of time. Ironically, the companies which will benefit most in the short term are the high-frequency traders themselves, who already have the technology to trade speedily, and now don't need to worry about investing more on ever-diminishing returns. But eventually, more and more traders will match that capability, until the market becomes a level playing field again.

The other reason why traders – even high-speed ones – ought to thank EBS is that if the exchanges get HFT under control, then there's one less reason for governments to step in. Discouraging high-frequency trades is one of the strongest reasons for introducing a financial transaction tax. That hits everyone, not just the speedy traders.

Will the collapse of the EU/Canada trade deal speed the demise of Jean-Claude Juncker?

The embattled European Comission President has already survived the migrant crisis and Brexit.

Jean-Claude Juncker, the embattled President of the European Commission, is likely to come under renewed pressure to resign later this week now that the Belgian region of Wallonia has likely scuppered the EU’s flagship trade deal with Canada.

The rebellious Walloons on Friday blocked the Comprehensive Economic and Trade Agreement (CETA). The deal for 500 million Europeans was at the final hurdle when it fell, struck down by an administration representing 3.2 million people.

As Canada’s trade minister, Chrystia Freeland, walked out of talks in tears and declared the deal dead, fingers were pointed at Juncker. Under pressure from EU governments, he had agreed that CETA would be a “mixed agreement”. He overruled the executive’s legal advice that finalising the deal was in the Commission’s power.

CETA now had to be ratified by each member state. In the case of Belgium, it means it had to be approved by each of its seven parliaments, giving the Walloons an effective veto.

Wallonia’s charismatic socialist Minister-President Paul Magnette needed a cause celebre to head off gains made by the rival Marxist PTB party. He found it in opposition to an investor protection clause that will allow multinationals to sue governments, just a month after the news that plant closures by the world’s leading heavy machinery maker Caterpillar would cost Wallonia 2,200 jobs.

Juncker was furious. Nobody spoke up when the EU signed a deal with Vietnam, “known the world over for applying all democratic principles”, he sarcastically told reporters.

“But when it comes to signing an agreement with Canada, an accomplished dictatorship as we all know, the whole world wants to say we don’t respect human right or social and economic rights,” he added.  

The Canadian Prime Minister Justin Trudeau was due to arrive in Brussels on Thursday to sign CETA, which is backed by all EU leaders.

European Council President, Donald Tusk, has today spoken to Trudeau and his visit is currently scheduled to go ahead. This morning, the Walloons said they would not be held to ransom by the “EU ultimatum”.

If signed, CETA will remove customs duties, open up markets, and encourage investment, the Commission has said. Losing it will cost jobs and billions in lost trade to Europe’s stagnant economy.

“The credibility of Europe is at stake”, Tusk has warned.

Failure to deliver CETA will be a serious blow to the European Union and call into question the European Commission’s exclusive mandate to strike trade deals on behalf of EU nations.

It will jeopardise a similar trade agreement with the USA, the Transatlantic Trade and Investment Partnership (TTIP). The Commission claims that an “ambitious” TTIP could increase the size of the EU economy by €120 billion (or 0.5% of GDP).

The Commission has already missed its end of year deadline to conclude trade talks with the US. It will now have to continue negotiations with whoever succeeds Obama as US President.

And if the EU cannot, after seven years of painstaking negotiations, get a deal with Canada done, how will it manage if the time comes to strike a similar pact with a "hard Brexit" Britain?

Juncker has faced criticism before.  After the Brexit referendum, the Czechs and the Poles wanted him gone. Hungary’s Prime Minister Viktor Orban muttered darkly about “personnel issues” at the Commission.

In July, it was reported that Angela Merkel, the most powerful politician in Europe, was plotting to oust Juncker. Merkel stayed her hand, and with German elections looming next year is unlikely to pull the trigger now.

When he took office in November 2014, Juncker promised that his administration would be a “political Commission”. But there has never been any sign he would be willing to bear the political consequences of his failures.

Asked if Juncker would quit after Brexit, the Commission’s chief spokesman said, “the answer has two letters and the first one is ‘N’”.

Just days into his administration, Juncker was embroiled in the LuxLeaks scandal. When he was Luxembourg’s prime minister and finance minister, the country had struck sweetheart tax deals with multinational companies.  

Despite official denials, rumours about his drinking and health continue to swirl around Brussels. They are exacerbated by bizarre behaviour such as kissing Belgium’s Charles Michel on his bald head and greeting Orban with a cheery “Hello dictator”!

On Juncker’s watch, border controls have been reintroduced in the once-sacrosanct Schengen passport-free zone, as the EU struggles to handle the migration crisis.

Member states promised to relocate 160,000 refugees in Italy and Greece across the bloc by September 2017. One year on, just 6,651 asylum seekers have been re-homed.

All this would be enough to claim the scalp of a normal politician but Juncker remains bulletproof.

The European Commission President can, in theory, only be forced out by the European Parliament, as happened to Jacques Santer in 1999.

The European Parliament President is Martin Schulz, a German socialist. His term is up for renewal next year and Juncker, a centre-right politician, has already endorsed its renewal in a joint interview.

There is little chance that Juncker will be replaced with a leader more sympathetic to the British before the Brexit negotiations begin next year.
