NEW YORK CITY-The latest lease at 7 World Trade Center has brought the building to full occupancy. MSCI Inc., a provider of investment decision support tools, has signed a 20-year lease for about 125,000 square feet in the building. MSCI will consolidate its New York locations—including the company’s One Chase Plaza world headquarters—in the move, anticipated for mid-2012.

The company will join a varied list of tenants in the building, including Ameriprise Financial, Moody’s Corp., the New York Academy of Sciences and Broadcast Music, Inc.

“I am thrilled to welcome MSCI to the stellar roster of top-tier companies at 7 World Trade Center,” Larry Silverstein, president & CEO of Silverstein Properties said in a prepared statement. “The success of 7 World Trade Center is proof that in New York City, first-class office buildings always fill up. It also reaffirms our belief that our other buildings at the new World Trade Center will be just as successful.”

Cushman & Wakefield EVPs Gary Greenspan and Michael Burgio represented the tenant in the lease. Silverstein Properties was repped in-house by EVP Roger Silverstein, SVP Jeremy Moss as well as CB Richard Ellis chairman, global brokerage Stephen Siegel and EVP Peter Turchin.
