The frustration Seattle residents feel toward Howard Schultz for selling the Sonics may be nothing compared to the potential legacy of Washington Mutual CEO Kerry Killinger. What's the move of a basketball team compared to losing a major corporate headquarters?

The $7 billion capital infusion led by the private-equity outfit TPG may have saved the nation's largest savings and loan. But for what future remains to be seen.

WaMu has long been an outlier: a major financial services company not based in New York or Charlotte, N.C.; a savings and loan still growing nearly two decades after the thrift industry collapsed into one of the biggest financial debacles in history, an independent at a time of historic consolidation.

When times were good, this brought major benefits to Seattle. The company remade the skyline with two towers, including its 42-story world headquarters; backed the WaMu Theater at Qwest Field, and was instrumental in the expansion of the Seattle Art Museum. It created thousands of good jobs.

Lately, it's meant layoffs — another 3,000 job cuts were announced Tuesday, on top of 3,300 set for elimination in December — and morale-killing uncertainty.

And the worst may yet be to come.

If the financial sector falls deeper into the credit crisis, WaMu's capital infusion may not be enough to stem its troubles and a shareholder revolt. WaMu's announcement of more job cuts, big losses and dividend reductions may only be the first of many pounds of flesh to be extracted, especially if the worst of the credit crisis is not over.

But even if the infusion succeeds, it may lead to the company being sold and the loss of a major headquarters.

The first hurdle will be whether TPG made the right bet. Private equity, which in the early 2000s roamed the economy to buy and fix distressed companies, has proved itself painfully fallible in recent months. It was highlighted by the collapse of the Carlyle Capital Corp., a unit of the once high-flying Carlyle Group private equity firm, which became mired in $22 billion in mortgage-backed securities.

Texas Pacific Group, which has been around since 1992, claims $30 billion under management. It has the chops to send a message: after the Fed bailout of Bear Sterns and other major Fed infusions, the mortgage meltdown has hit bottom, or at least become clearer.

TPG is not a "rip, strip and flip" operation, but usually takes positions for longer periods of time and leaves day-to-day management to the companies themselves. Whether that management should be left to Killinger, the architect of the string of missteps that brought WaMu to the edge of the abyss, should make for some interesting boardroom politics.

Killinger has counted on a friendly board; now two seats will go to TPG. It also remains to be seen if other big shareholders, who had considered mounting a challenge to the board will be mollified.

TPG's historic patience may be under pressure, too. Along with Kohlberg, Kravis Roberts & Co., it bought Texas power generator TXU Corp. (now called Energy Future Holdings) last year in a leveraged buyout that added $40 billion in debt. The revenue it expected from the utility's cash flow, which has proved disappointing.

Ultimately, TPG expects to provide a big return to its investors from its bet in Seattle. That will likely come from an acquisition. J.P. Morgan Chase was reportedly looking at WaMu.

Seattle may think it already has the scar tissue to withstand another headquarters loss, especially having survived the loss of Boeing. But losing a banking institution headquarters is arguably more painful. While much of Boeing's talent remained here even when the bosses decamped for Chicago, the loss of Washington Mutual's headquarters would mean losing many more highly paid corporate jobs. WaMu employs 4,400 in downtown Seattle alone. It would also be a calamity for commercial real estate as whole floors of two buildings empty out.

I worked in Charlotte in the 1990s as that city's big banks gobbled up major regional institutions around the country. In every case, thousands of jobs in the old headquarters city were eliminated or moved to Charlotte. Not only were good jobs lost, but communities were severely destabilized. Gone were the local CEOs who could write checks and knock heads to address community challenges. Gone was the local banking supply chain of vendors. Giving and stewardship were badly diminished. In many cities, these benefits were never replaced.

The headquarters of major banks (and large S&Ls) are unique assets. They are among a small group of industries today that typically employs a large concentrated headquarters workforce, hence they are bulwarks of downtown real estate. They represent centers of capital and talent.

Having seen banking consolidation build an Oz-like skyline in Charlotte, I then witnessed the other end of the pipeline in Phoenix. It's the nation's fifth most populous city, but has no major bank headquarters. That helps account for the struggling downtown, a surprising lack of corporate level jobs, and a dearth of capital for businesses beyond real estate (and now even that has dried up).

Seattle won't face such a dreary fall. Its economy is too diverse and deep, including in leading-edge industries. But if the powerful forces of banking consolidation and investor impatience combine to take away Washington Mutual, the pain will last long beyond the last home game of the Sonics.
