Overview
CoreStates Financial Corporation was an American bank holding company centered in Philadelphia and serving the broader Mid-Atlantic banking market. Its institutional roots reached back to the founding of The Philadelphia Bank on September 8, 1803, under the leadership of its first president, George Clymer. The institution later became known as Philadelphia National Bank, commonly abbreviated as PNB, before adopting the CoreStates identity during a period of regional banking consolidation in the 1980s. The company's history reflected the development of Philadelphia as an important American financial center. PNB operated as a commercial bank, providing corporate, institutional, retail, and correspondent banking services. It maintained an international correspondent-banking presence, including operations associated with Philadelphia International Bank in London and New York, and developed relationships with companies and financial institutions in the Middle East during the expansion of oil-rich economies in the late twentieth century. PNB was also associated with several initiatives that shaped its regional reputation. During the late 1960s, it was described as an early large-bank opponent of redlining and sought to expand personal and small-business lending in lower-income Philadelphia neighborhoods. During the 1970s, it developed the MAC, or Money Access Center and Money Access Card, network of automated teller machines. The network helped broaden the availability of ATM banking and became an important consumer-facing service associated with the bank. CoreStates emerged from a series of mergers beginning with the 1982 combination involving Hamilton Bank of central Pennsylvania and subsequent expansion into New Jersey and Delaware. The company acquired First Pennsylvania Bank in 1990, bringing together two major Philadelphia banking legacies. First Pennsylvania had itself developed from the Pennsylvania Company for Insurance on Lives and Granting Annuities and related predecessor institutions, including the Bank of North America lineage. CoreStates later paid $20 million for twenty-year naming rights to Philadelphia's new sports arena, which opened as the CoreStates Center and became a prominent example of the company's regional branding. In 1995, CoreStates acquired Meridian Bancorp for approximately $3.2 billion, at the time its largest acquisition. The transaction strengthened the company's position in the Mid-Atlantic region and brought George W. Strawbridge Jr. onto the board as a major shareholder. CoreStates was acquired by First Union Corporation in 1998 in a transaction valued at approximately $17 billion, then the largest bank merger in United States history according to contemporary accounts. The CoreStates identity was subsequently absorbed into First Union's banking structure. First Union acquired Wachovia Corporation's banking operations in 2001 and adopted the Wachovia name for the combined company. During the 2008 financial crisis, Wachovia was acquired by Wells Fargo & Company. As a result, former CoreStates branches, assets, offices, and customer relationships ultimately became part of the Wells Fargo organization. The original CoreStates and Philadelphia National Bank brands are therefore defunct as independent banking brands, although several Philadelphia buildings and civic projects continue to reflect their historical presence.
History
The institution that became CoreStates Financial Corporation was founded in Philadelphia on September 8, 1803, as The Philadelphia Bank. George Clymer served as its first president. As Philadelphia developed into one of the United States' principal financial centers, the bank became known as Philadelphia National Bank, or PNB. PNB operated alongside older and historically important Philadelphia institutions. One of the most significant was the Pennsylvania Company for Insurance on Lives and Granting Annuities, which moved into banking during the nineteenth century and later acquired the Bank of North America lineage. After a 1955 combination with First National Bank, the institution became associated with First Pennsylvania Bank. These separate Philadelphia banking histories eventually converged when CoreStates acquired First Pennsylvania in 1990. PNB developed a reputation for conservative management and civic engagement. In the late 1960s, it was identified with efforts to end redlining practices and extend personal and small-business credit to poorer Philadelphia neighborhoods. During the 1970s, the bank helped expand ATM access through its MAC network, with the name referring to Money Access Center or Money Access Card. The network was among the more extensive early automated banking systems in the United States. The competitive environment changed substantially in the late 1970s and 1980s. High interest rates, real-estate weakness, and increased competition encouraged banks to seek scale through mergers. PNB had a broad correspondent-banking network and international offices connected with Philadelphia International Bank in London and New York. It also pursued business in developing Middle Eastern markets, while avoiding some of the real-estate exposure that weakened First Pennsylvania during the period's real-estate investment trust downturn. PNB's first major merger in the modern consolidation period involved Hamilton Bank of central Pennsylvania in 1982. The company subsequently took control of New Jersey National Bank of Trenton and adopted the CoreStates identity during the mid-1980s. CoreStates Bank of Delaware served corporate borrowers in Delaware, including major industrial companies such as DuPont. The acquisition of First Pennsylvania in 1990 expanded CoreStates' Philadelphia presence and reunited important local banking histories. The company also pursued prominent civic and marketing projects. It paid $20 million for twenty-year naming rights to a new Philadelphia arena beside the Spectrum; the facility opened as the CoreStates Center. The company's former headquarters at One South Broad remained a visible landmark in Center City, while another office complex at Fifth and Market Streets housed operations divisions. In connection with the latter development, the bank participated in rebuilding the nearby SEPTA station at Fifth Street and Independence Hall. CoreStates continued expanding in the 1990s. Its 1995 acquisition of Meridian Bancorp, valued at approximately $3.2 billion, was its largest acquisition to that point. The transaction reinforced the company's regional scale and brought George W. Strawbridge Jr., a Meridian shareholder and Philadelphia-area business figure, onto the CoreStates board. In 1998, First Union Corporation of Charlotte, North Carolina, acquired CoreStates for approximately $17 billion. This transaction ended CoreStates as an independent company. First Union later acquired Wachovia National Bank in 2001 and used the Wachovia name for the combined business. Wachovia was subsequently acquired by Wells Fargo in 2008 during the financial crisis. Former CoreStates businesses and facilities therefore passed through First Union and Wachovia into Wells Fargo, while CoreStates itself became a defunct historical banking brand.
