Are Wall Street firms doing the unthinkable: Actually returning to Wall Street? The New York Post and New York magazine's web site report that HSBC might move into the new 7 World Trade Center. Not only is the global bank set to leave midtown and lease 300,000 square feet of office space in the newly completed building, HSBC has reportedly put its 452 Fifth Avenue offices on the market.

In other financial giant news: Waters and its sibling publications -- Dealing with Technology and Inside Market Data -- will move down to 120 Broadway in the financial district in the next three weeks. So long, SoHo, we'll miss you.
