Effective as of 1pm EDT (10am PDT) today, August 21, 2007, 1st National Bank of Arizona (FNBA) will focus on Retail originations and has suspended Wholesale and Correspondent originations.

FNBA’s mortgage operations grew to $7.3 billion in 2006, according to the company’s annual report; it isn’t clear if this is fundings or total value of the bank’s mortgage book. The bank is primarily focused on Alt-A mortgages. FNBA’s wholesale mortgage division operated in 49 states and employed 625 staff, according to a review of company documents. It isn’t clear if this suspension entails the closing of each operating division, and/or how many jobs may be affected by the bank’s decision.
