Banking on technology to stop the rogues

AppId is over the quota
AppId is over the quota
26 September 2011 Last updated at 23:05 GMT By Michael Millar Business reporter, BBC News WATCH: Risk averse: Used correctly, technology could help to avoid losses like UBS trader Kweku Adoboli's $2.3bn

When news broke that Swiss investment bank UBS had lost $2.3bn (£1.5bn) through alleged rogue trading, the shock was matched by an equally exasperated response of "not again!" as another financial risk management disaster hit the headlines.

After all, not only did the suspected trader, Kweku Adoboli, work in a 'Delta 1' team - the same desk that the biggest ever rogue trader, Jerome Kerviel of Societe Generale, once plied his trade - but the world continues to reel from a global financial crisis which itself stemmed from a monumental failure of risk management amongst financiers.

It leaves a sceptical public scratching its collective head and wondering just what needs to happen for risk to be kept under control in the financial sector.

It might sound surprising but there is no question whether managing risk is a central obligation for financial firms.

"Under UK company law all companies are required to have a duty of care towards shareholders assets and that includes risk management," explains Prof Brian Scott-Quinn from Henley Business School.

"Under FSA rules they have additional responsibilities, they have to take reasonable care to ensure that any activities in control functions [essentially roles with 'significant influence'] are properly controlled," he adds.

But it is no mean feat to do this; across August an average of 880,000 trades were completed each day on the London Stock Exchange alone, with an average daily value of £6.17bn.

Financial firms have back-office functions that are there to confirm transactions are above board, but such is the volume that the only way they can keep up is with increasingly advanced technology.

Technology kicks in

Mat Newman is vice-president at SunGard; its software processes millions of transactions for its financial sector clients every day.

"The interconnectedness of what banks are trying to do across different geographies, different time zones and different trading desks, and asset classes is just immense these days," he says.

"One of the key things banks are faced with as a challenge is how to bring this together, this vast amount of data and make sense of it at the same time - so they can see the wood for the trees."

Without such technology companies don't have a hope of gathering the information they need, analysing it and presenting it to the right people at the right time.

"These days you have systems that will monitor your current positions against those risks and you have a whole series of bells and whistles that will flag not just if you breach those limits but if you come close to those limits," says Mark Hanney, CEO of Valbury Capital stockbrokers.

This is crucial for Valbury Capital, which takes trades from clients and then passes them on to the markets, theoretically running a no-risk business model.

Mark Hanney Mark Hanney: "You have a whole series of bells and whistles"

"If a client is trading with us they put up a certain amount of margin, and if that margin is insufficient for their positions then our systems can automatically stop them out," Mr Hanney explains.

"Those systems can apply internally as well, so if a trader goes beyond a certain position then those systems are able, once they've breached those limits, to automatically close the position out."

The "bells and whistles" that flag up problems come in all shapes and sizes, dependent on the technology a firm opts for.

"Exceptions can be flagged graphically on summary dashboards with a number of graphical metaphors employed in the form of traffic lights, dials and graphs," says Daren Cox, CEO of Project Brokers, which supplies data analysis tools to investment banks.

He says that graphics rather than tables of data are often favoured simply because they mean that potential problems are easier to spot.

There are certain key areas of risk on which the technology is often brought to bear.

These include liquidity risk (how much cash you have and whether you can meet your obligations), market risk (what's going on out there in the markets) and one of the biggest of all, credit risk - basically how much people owe you and whether they are going to be able to pay it back.

Abusing the system

With the key flash points picked out and technology that can make a decision on whether a deal is a good idea in less than 10 milliseconds, the obvious question is why things seem to go wrong so regularly?

"One of the main problems these days - as it was in 2008 - is not the system but its operators," says Michel van Leeuwen, CEO of financial compliance consultancy, IMS.

"Their intelligence, experience, vigilance, their clout in the hierarchy and the simple analogy of 'having a clock' is irrelevant if you never look at it or don't look at it frequently."

Technology is also open to manipulation if you know how.

"Part of the problem is the rogue traders we have seen in the past have come from a back office function and they know these processes very well," says Mat Newman of SunGard.

"What's quite common in the City is to grow your own talent from the back office and bring it through to the front office."

Mr van Leeuwen calls this "akin to inviting the cat into the pigeon coop".

"It would be wise not to hire a trader that used to be a... back office employee," he says.

"The imperative, regulator imposed, 'Chinese wall' imposed in process and procedures, doesn't seem to have made it to the frontal lobe of HR or the heads of trading."

Positive thinking

There is a temptation with financial crisis in the air and an angry public after blood to overemphasise the down side of the risks financial institutions take.

But John Macdonald, executive vice-president at financial software firm Algorithmics, says risk management technology should not just be a way to stamp down on transgressors.

"Any one transaction can be analysed by one individual but it may take some time - if you have a customer you provide banking services to they don't want to wait two or three days for a decision," he says.

"Businesses need to be able to have access to funding and making the right decisions helps the economy grow.

"That's all part of risk management - being able to measure and then decide what level of risk you decide to take because you make a return on the capital you use by taking risk."

Of course there will be those that argue that on occasion slowing everything down a bit and taking a day or two rather than a thousandth of a second to mull a deal over might be a good thing.

Making Olympic technology work

AppId is over the quota
AppId is over the quota
28 September 2011 Last updated at 23:07 GMT Matthias Steiner of Germany competes at the 2008 Beijing Olympic Games Weighty task: Making the technology for the London Olympics work is a "huge responsibility" says chief integrator Michele Hyron Each week we ask high-profile technology decision-makers three questions.

Michele Hyron Michele Hyron: Viewers will be able to choose which competition, nation or athlete they want to follow

This week it is Michele Hyron of Atos,?chief integrator for the Olympic Games in London. She is responsible for leading the consortium of IT partners to design, build and operate the massive IT infrastructure that will support the London 2012 Games.

Ms Hyron leads a team that include employees from Atos and technology partners LOCOG, as well as volunteers.

She already has nearly 10 years of Olympic Games experience, serving as operations manager at the Beijing 2008 Olympic Games, integration manager at Athens 2004 and quality manager at the winter Games in Salt Lake City 2002.

What's your biggest technology problem right now?

As the chief integrator for the London 2012 Olympic and Paralympic Games, I suppose that people would expect me to have a long list of problems. After all, if the IT doesn't work, then effectively the Games can't take place.

It is a huge responsibility, and one that everyone takes extremely seriously, but this is now my third Olympic Games and Atos's sixth.

While the technologies advance every time and we are faced with fresh problems as we integrate new applications, we have developed a robust process that ensures that we test everything in the lab over and over again.

By the time we get to the Games themselves, we have covered an extensive testing program.

In fact, our work is analogous to training pilots in aircraft simulators.

We throw every possible scenario at the IT teams - from the failure of the communications network to someone accidentally pulling out a plug - and ensure that we can recover from these without anyone at the Games or watching on TV noticing that a problem has even occurred.

The most challenging aspect of the job, though, is undoubtedly the massive increases in the amount of data which has to be organised and channelled with split-second timing.

It is estimated that between the dawn of civilisation - some four to five thousand years ago - and 2003, mankind had created about five exabyte's of data, which is 5bn gigabytes.

Across the world, we now create that amount of data every two days and the volume of business data is doubling every 18 months.

The Olympic Games is no exception. For Beijing, we produced 50% more data than we handled at the Athens Games.

The London 2012 Games will see us process significantly more information than we had at Beijing, as we meet the demands of sports fans worldwide for the latest information on their favourite events and sports stars, and deliver this information via broadcasters, internet and mobile.

Technology of Business What's the next big tech thing in your industry?

Atos is a global business with a presence in more than 42 countries and a workforce of 78,500 business technologists. In many respects our industry covers virtually every aspect of IT and every industry sector.

However, from my personal perspective it is the magic that we can now work with metadata to create a completely different TV experience for watching sport which is the most exciting.

We will have the ability to offer viewers the chance to choose exactly which competition, nation or athlete they want to follow, and enable them to follow more than one sporting event simultaneously.

This digital quality service will be offered over fixed and mobile devices, and is designed to allow sports fan to watch events that aren't even being broadcast on a regular programme.

So unlike the type of technologies people are used to today, with a personal video recorder (PVR) integrated into a set-top box allowing them to select when they view broadcasts, this new approach makes the viewer the director, selecting what they watch, when and from what angle.

Our approach incorporates face-recognition technologies, and this means that a viewer can either have automatic selection of the best shot or a recommendation that they can accept or reject.

The amount of data that has to been managed to offer this service is staggering, and by 2014 we estimate that more than 90% of all data traffic in the world will be video content.

It will be the equivalent of 32 million people streaming Avatar in 3D continuously every month.

London view What's the biggest technology mistake you've ever made - either at work or in your own life?

As a complete beginner in software development, at the start of my career, I enjoyed developing a program in Assembler.

I made it as compact as possible, playing with the stack and using other tricks. It was great fun!

What I didn't appreciate at the time was that this piece of code was completely unmaintainable.

My colleagues were still blaming me for this work years after I moved on to other things.

It was a really good lesson so early on in my career, and taught me the importance of looking ahead and appreciating the impact of what I do, not just tomorrow but years into the future.

It also taught me that while playing with software is really fun - and it is - delivering programs that are robust and practical is what counts.
