UBS Loses $2 Billion: Part I

The financial world was rocked by a scandal last week. UBS, the giant Swiss bank, announced losses of over $2 billion in unauthorized trades. The losses were generated by one trader in their London office.

The obvious reaction is "Two billion dollars! How does one guy lose two billion dollars?"

We don't know yet, and the details will only trickle out over the next few weeks. Already this weekend, UBS has revealed that the trades that generated the losses occurred over a period of about three months, and that the total losses came to about $2.3 billion.

"Two point three billion dollars! How does one guy lose two point three billion dollars?"

We have now seen enough of these "rogue trader" cases to make a few predictions about the story that will emerge as the investigation continues.

1. It started out much smaller. These guys don't start out placing $2 billion bets in the giant global casino known as our modern capital markets. Far more likely is that he screwed up some trades, maybe from something as mundane as a keystroke error. "Sell a million euros at the preset price. At most I'll lose a million. Holy crap, how did that extra zero get in there!" You lose a big enough chunk of money, and you will get fired. So now the thought process runs "I can't tell my boss about losing $10 million; I'll get fired. And my swanky bachelor pad costs $10 grand a month in rent. I have to earn that money back."

2. Risk controls were defeated. In the giant global casino known as our modern capital markets, the senior management of the investment banks is aware that it might not be the best idea to hand company credit cards with no limit out to a bunch of testosterone fueled 25-30 year olds who are amped up on Red Bull. So instead, they give them cards with credit limits. Essentially, every bank has systems in place to measure how much the bank could potentially lose from each trader's positions. In every case of a "rogue trader" those systems have been circumvented. Part of the problem here is that the big money is made by trading, and coming up with newer, ever more exotic financials instruments. The small money is made by working in risk management. The best and the brightest aren't clamoring to work in the field.

3. The problem got much bigger quickly. Once you've lost a bunch of money, decided to try and make it back, and figured out how to make bigger and bigger trades without senior management catching on, you start doubling down on your trading positions. Trading positions are what ordinary people would call betting, but we don't work in the giant global casino known as our modern capital markets. Let's say you start by losing $10 million. You place another $10 million bet to get it back. Once you lose that, now you've got to make $20 million back. The losses can grow geometrically at this point. If you double down and lose it all every time, it only takes 8 trades to get to the level of losses experienced by UBS.

The rest of this story will eventually emerge. When it does, I'm going to try and put the details into plain English.
