Continental Illinois
Continental Illinois was a major Chicago commercial bank whose 1984 rescue helped establish the modern meaning of the phrase “too big to fail.”

Overview
Continental Illinois was a large Chicago-based commercial bank that became one of the most consequential institutions in the history of United States banking regulation. Its roots lay in two earlier Chicago banks: Commercial National Bank, founded during the American Civil War, and Continental National Bank, founded in 1883. Their 1910 combination created Continental & Commercial National Bank of Chicago, which began with approximately $175 million in deposits. The institution adopted the name Continental Illinois National Bank and Trust Company in 1932. For much of the twentieth century, Continental Illinois developed as a wholesale and corporate bank rather than primarily as a consumer branch network. It provided commercial lending, correspondent banking, trust services, corporate finance, investment banking-related services, and specialized credit to sectors such as energy. At its peak it ranked as the seventh-largest commercial bank in the United States by deposits and reported approximately $40 billion in assets. Its national profile was strengthened by its willingness to lend beyond the traditional geographic base of a Chicago bank. That growth strategy created significant vulnerabilities. During the energy boom of the late 1970s and early 1980s, Continental Illinois expanded its exposure to oil and gas producers, service companies, and investors connected with the Oklahoma and Texas energy markets. It also purchased a substantial volume of loans originated by Penn Square Bank of Oklahoma. When energy prices weakened and Penn Square failed, the quality of those loans deteriorated rapidly. The bank was accused of having performed inadequate due diligence on some of the acquired credits, while weaknesses in underwriting and oversight increased the scale of the losses. The resulting loss of confidence produced a severe deposit run in May 1984. Large depositors withdrew more than $10 billion in a short period, and regulators concluded that an uncontrolled failure could destabilize other banks and financial markets. The Federal Reserve and the Federal Deposit Insurance Corporation therefore arranged an extraordinary intervention. The FDIC guaranteed virtually all deposit accounts and protected bondholders, supplied billions of dollars of support, and removed the bank’s board and senior management. The rescue was widely described as the largest United States bank failure and bailout to that date. Congressional discussion of the intervention helped popularize “too big to fail” as a description of regulatory policy toward systemically important banks. After the rescue, the institution was renamed Continental Bank. The federal government effectively controlled approximately 80 percent of the company’s shares and gradually restructured the bank under new leadership. The government eventually exercised its right to acquire the remaining shares in 1989 and sold its holdings to private investors on June 6, 1991. Continental continued operating as a commercial bank, but its independence was temporary. In 1994, Bank of America acquired Continental Bank to expand its Midwestern presence. Continental’s former Chicago headquarters and portions of its operations subsequently became part of Bank of America’s regional organization. The later acquisition of LaSalle Bank in 2007 further expanded Bank of America’s Chicago franchise, but Continental Illinois itself no longer exists as an independent banking brand.
History
Continental Illinois emerged from the consolidation of two Chicago institutions. Commercial National Bank traced its origins to the Civil War era, while Continental National Bank was established in 1883. In 1910 they merged to form Continental & Commercial National Bank of Chicago, creating a substantial institution with about $175 million in deposits. The bank adopted the Continental Illinois National Bank and Trust Company name in 1932. The institution grew into one of the United States’ largest commercial banks. Its business concentrated on corporate and wholesale banking, including commercial credit, correspondent relationships, trust activities, and financing for specialized industries. Continental Illinois expanded its lending beyond Chicago and became particularly active in energy finance during the oil and gas boom of the late 1970s and early 1980s. This expansion increased both its national importance and its exposure to cyclical credit risk. A central problem was the bank’s purchase of loans originated by Penn Square Bank, an Oklahoma institution heavily involved in oil and gas lending. Many of the underlying borrowers were producers, service companies, and investors connected with the Oklahoma and Texas energy boom. When the energy market weakened and Penn Square failed, a large portion of the acquired loan book proved impaired. The failure exposed weaknesses in underwriting, monitoring, and due diligence. John Lytle, an executive associated with Continental’s Mid-Continent oil-lending division, later pleaded guilty to defrauding the bank and accepting kickbacks in connection with risky loan approvals. He received a federal prison sentence. By May 1984, doubts about Continental’s solvency caused a large deposit run. More than $10 billion was withdrawn by large depositors, placing pressure on the bank and on the broader financial system. The Federal Reserve and FDIC judged that Continental’s size and interconnectedness made an uncontrolled failure dangerous. They consequently guaranteed essentially all deposit accounts and protected bondholders, even though shareholders suffered substantial losses. The FDIC supplied approximately $4.5 billion in direct rescue funding, while the overall intervention was described in contemporary accounts as involving several billion dollars of new capital and emergency loans. The board and senior management were removed, and the bank was placed under new management. The rescue became a landmark in financial regulation. During a 1984 congressional hearing, Representative Stewart McKinney used the phrase “too big to fail” to characterize the government’s treatment of Continental Illinois. Although the expression had appeared occasionally before, the Continental case gave it lasting prominence as a description of the expectation that authorities would support a systemically important bank to prevent wider damage. After the intervention, the bank was renamed Continental Bank. The federal government effectively held about 80 percent of the company’s shares and retained rights over the remaining equity under the rescue arrangements. The government later acquired the remaining shares in 1989 and began returning the institution to private ownership. Its final government-held shares were sold on June 6, 1991. Continental Bank survived as an operating institution but did not remain independent. Bank of America acquired it in 1994 to strengthen its Midwestern business. Continental’s former South LaSalle Street headquarters in Chicago continued to be associated with Bank of America operations, while later transactions, including Bank of America’s 2007 purchase of LaSalle Bank, further reshaped the successor’s Chicago presence. Continental Illinois is therefore remembered both as a historic Chicago bank and as a defining example of the regulatory and moral-hazard issues surrounding government support for large financial institutions.

Products and positioning
A nationally significant Chicago wholesale bank emphasizing corporate, commercial, correspondent, and specialized-sector finance. Its reputation shifted from aggressive national growth to a prominent case study in bank-risk management, government rescue, and systemic importance.
Commercial and corporate bankingCommercial banking
Continental Illinois’s core business comprised lending and other financial services for companies, institutions, and large commercial customers. Its wholesale orientation helped the bank expand nationally and made it an important correspondent and corporate banking institution. The same growth strategy also concentrated substantial risk in cyclical industries and specialized credit markets.
Energy-sector financeIndustry lending
The bank financed oil and gas producers, service companies, and investors, particularly during the energy boom in Oklahoma and Texas. Energy lending became one of Continental’s most important specialized activities, but the subsequent downturn produced large losses and contributed materially to the 1984 insolvency.
Town and Country MastercardCredit card
Town and Country Mastercard was a credit-card program issued by Continental Illinois. In 1984, its assets and associated servicing operations were sold to Chemical Bank of New York. The servicing activities were subsequently moved and operated under the Chem Credit Services name.
First Options ChicagoSecurities clearing
First Options Chicago was an options-clearing operation acquired by Continental Illinois. It guaranteed settlement of customer trades, exposing the parent bank to substantial obligations when customers could not meet margin calls. The operation became a major subject of scrutiny after the 1987 market crash and required an emergency cash infusion from Continental.
Continental Illinois Venture CorporationVenture capital
Continental Illinois Venture Corporation was the bank’s investment subsidiary. It later helped form the semi-independent private-equity firm CIVC Partners with backing from Bank of America, linking a legacy Continental investment activity to a successor investment platform.

Controversies
- 1988First Options Chicago clearing-risk inquiryControversy
A congressional subcommittee investigated the risks created by First Options Chicago’s settlement guarantees after customers failed to meet margin obligations. The episode raised questions about the bank’s oversight of a highly leveraged financial-market operation and the potential for those risks to affect the wider banking system.
- 1984Energy-loan and Penn Square lending scandalControversy
Continental Illinois suffered major losses after purchasing and holding poorly performing loans connected with Penn Square Bank and the Oklahoma and Texas energy boom. Investigations identified inadequate due diligence and improper conduct in parts of the bank’s oil-lending operation. Executive John Lytle later pleaded guilty to defrauding Continental and accepting kickbacks for approving risky loan applications.
