Chase was primarily a wholesale bank dealing with other prominent financial institutions and major corporate clients such as General Electric,[17]: 450 which had, through its RCA subsidiary, leased prominent space and become a crucial first tenant of Rockefeller Center. They rescued that major project in 1930. The bank is also closely associated with and has financed the oil industry, having longstanding connections with its board of directors to the successor companies of Standard Oil, especially ExxonMobil, which are also part of Rockefeller holdings.
