Dallas is definitely the financial hub of the southwest. It has one of the twelve federal reserve banks in the US.
Here below is a summary from Wikipedia:

Dallas (pronounced /?dæl?s/) is the third-largest city in Texas[4][5] and the ninth-largest in the United States. Divided between Collin, Dallas, Denton, Kaufman, and Rockwall counties, the city had a 2010 population of approximately 1.2 million, according to the United States Census Bureau.[6] The city is the largest economic center of the 12-county Dallas–Fort Worth–Arlington metropolitan area that according to the March 2010 U.S. Census Bureau release, had a population of roughly 6.5 million as of July 2009.[7] The metropolitan area is the largest metropolitan area in the South and fourth-largest metropolitan area in the United States.[8]

Founded in 1841 and formally incorporated as a city in February, 1856, the city's economy is primarily based on banking, commerce, telecommunications, computer technology, energy, and transportation, home to several Fortune 500 companies.[9] Located in North Texas and a major city in the American South, Dallas is the core of the largest inland metropolitan area in the United States that lacks any navigable link to the sea.[10] The city's prominence arose from its historical importance as a center for the oil and cotton industries, and its position along numerous railroad lines. Dallas developed a strong industrial and financial sector, and a major inland port, due largely to the presence of Dallas/Fort Worth International Airport, one of the largest and busiest airports in the world.[11] It was rated as a beta world city by the Globalization and World Cities Study Group & Network.[12]
