The black box economy

The Boston Globe

Behind the recent bad news lurks a much deeper concern: The world economy is now being driven by a vast, secretive web of investments that might be out of anyone's control.

THE PAST YEAR has been a harrowing one for the world's financial markets, shaken by subprime crises, credit crunches, and other ills. Things have only gotten stranger in the past week, with stock prices swinging wildly in every major market - drastically down, then back up.


Last week the Federal Reserve announced the biggest cut in overnight lending rates in more than two decades. Congress, not to be outdone, is slapping together a massive deficit spending package aimed at giving the economy an emergency booster shot.

Despite the anxiety, nobody is stockpiling canned goods just yet. The prevailing assumption in today's economy is that recessions and bear markets come and go, and that things will work out in the end, much as they have since the Great Depression. That's because there's a collective confidence that the market is strong enough to correct itself, and that experts in charge of the financial system will understand how to mount a vigorous defense.

Should we be so confident this time? A handful of financial theorists and thinkers are now saying we shouldn't. The drumbeat of bad news over the past year, they say, is only a symptom of something new and unsettling - a deeper change in the financial system that may leave regulators, and even Congress, powerless when they try to wield their usual tools.

That something is the immense shadow economy of novel and poorly understood financial instruments created by hedge funds and investment banks over the past decade - a web of extraordinarily complex securities and wagers that has made the world's financial system so opaque and entangled that even many experts confess that they no longer understand how it works.

Unlike the building blocks of the conventional economy - factories and firms, widgets and workers, stocks and bonds - these new financial arrangements are difficult to value, much less analyze. The money caught up in this web is now many times larger than the world's gross domestic product, and much of it exists outside the purview of regulators.......
