The Chatham Phenix National Bank and Trust Company was a bank in New York City connected with the Chatham Phenix Corporation. Its predecessor Chatham and Phenix National Bank was formed in 1911 when Chatham National Bank paid $1,880,000 to absorb the asset of the Phenix National Bank. The bank grew significantly as it absorbed smaller banking institutions, such as Mutual Alliance Trust Company and Century Bank in 1915, at which point Chatham and Phenix National Bank became the "first national bank to operate branches in the same city with the main bank."
