A study released today by Austin-based Sheshunoff and Co. Investment Banking reveals that the state of the banking industry in Texas is strong -- except in Dallas-Fort Worth, where the assets-to-loans ratio is on par with the woeful national average. Notes a managing partner in the banking industry advisory firm, "Dallas is running very close the national average. They have a lot of diversity in their industries, less oil and gas, and lots of banks, which creates more competition and as a result, they may have offered lower rates. Dallas is really a hub of the nation, and reflects the national trend in banking.” Here's a very detailed breakdown of DFW-area banks, extending all the way from Waxahachie to Farmersville. Included: years in which the banks were founded. Not included: money now kept under area mattresses. --Robert Wilonsky
