Depending on your point of view, we're either on the verge of -- or in the middle of -- a telecommunications-led recession. Every day, the papers are filled with news of more financial stress in what had been the global economy's fastest-growing segment.

How big a problem is the telecom meltdown? Business Week recently described the industry's staggering debt load as a "ticking time bomb." It noted that major telecom companies in the United States and Europe have nearly $700 billion worth of debt on their balance sheets. "Analysts estimate that more than $100 billion in junk bonds will end up in default or restructured." More than $100 billion in defaulted debt was the initial estimate of the savings-and-loan crisis of the late 1980s. The final cost was roughly $150 billion -- and a brief but harrowing recession.

Among those firms holding telecom bonds today are the California Public Employees Retirement System (CalPERS), Fidelity, Metropolitan Life, New York Life, Prudential Investment Management, State Farm Insurance,Wellington Management, and Zurich Scudder Investments. Syndicators of telecom loans include Bank of America, the Goldman Sachs Group Inc., J.P. Morgan Chase & Co., Salomon Smith Barney -- in short, every blue-chip financial-services organization you can name.

The Federal Reserve Board doesn't much care whether individual telecom companies go belly-up, as some already have done this year. But it does care when major financial institutions are destabilized by those same bankruptcies -- which probably explains why Fed chairman Alan Greenspan has moved so aggressively to cut interest rates and contain the collateral damage of the telecom meltdown. What we don't know is whether the Fed's intervention will work.

What we do know is that the future of telecommunications -- wireless technology -- has taken a big hit at exactly the moment that it could least afford to. In Europe, $300 billion in wireless investment (roughly $150 billion for licensing fees and $150 billion in third-generation, or 3G, network buildout costs) has added so much debt to the balance sheets of companies like British Telecom (BT), Ericsson, and Deutsche Telekom that at least one of them will have to be acquired to survive. Even in Japan, where NTT DoCoMo was assigned its wireless spectrum at no cost, the rollout of 3G services has been pushed back until later this year. Everywhere you look, wireless operators and the companies that supply them are struggling.

Every financial trick in the book is being deployed to keep things afloat -- at a time when demand for wireless services has (one hopes temporarily) crested. As in all business cases like this, the near future promises bankruptcies and liquidations, mergers and acquisitions, consolidation and rationalization. Where there were once many players, there will soon be two or three at most. It will not be pretty. But, pretty or not, it will be. We are moving inexorably toward a wireless world. The question is whether consumer demand will be able to sustain a fully built-out third-generation wireless network.
