As it sheds its California tagline and rebrands itself as a national institution, Union Bank is also moving to expand its treasury services business.

Union Bank has seen an influx of funds from corporate clients, as have other banks with stronger asset quality, says Todd Gregory, the senior vice president who leads the treasury services division. The treasury group's deposits have grown by more than a third since the U.S. economic turmoil began as companies search for safety in the current credit environment. “The uncertainty among the clients is probably the greatest I've ever seen it in 25 years,” he says.

“We're taking highly rated resources within the bank and we're applying those with a broader reach, with more focus and more people,” Gregory says, noting that the Union Bank's treasury services is already ranked among the top 10 cash management providers by Ernst & Young.
