Bank of Oklahoma Online Banking

Bank of Oklahoma was founded in 1910 as the Exchange National Bank of Tulsa that rose from the Farmers National Bank that had previously failed. The Exchange National Bank of Tulsa survived The Great Depression thanks to wealthy oil men in Tulsa, two of which were J.A. Chapman and William G. Skelly, put their own money in to help it survive. It was reorganized as the National Bank of Tulsa in 1933 and in 1975, it became the Bank of Oklahoma (BOK).
