Citigroup vs JPMorgan Chase & Co.

The company was established as the City Bank of New York to finance the merchant communities of the growing Eastern seaboard. It quickly transformed into a major institutional player under the National Banking Acts, eventually building the first comprehensive international banking branches.

Sandy Weill orchestrated a monumental $140 billion merger between banking titan Citicorp and insurance conglomerate Travelers Group, creating the world's largest financial super-company. The massive corporate tie-up deliberately challenged and shattered the remaining foundational pillars of the Glass-Steagall Act.

Citigroup suffered catastrophic structural losses due to over-exposure to toxic collateralized debt obligations CDOs during the mortgage bust. The bank required an unprecedented $45 billion direct cash infusion alongside hundreds of billions in federal toxic asset backstops to ensure survival.

By mid-2026, Citigroup completed its most aggressive corporate reorganization in a generation, code-named Project Bora Bora. Guided by CEO Jane Fraser, the group aggressively divested structural retail banking units globally to focus purely on high-margin commercial banking assets.

One of JPMorgan Chase's oldest predecessor institutions was founded in 1799 by Aaron Burr — the U.S. Vice President who would later shoot and kill Alexander Hamilton in a duel. Burr obtained a charter for a water company to supply clean water to New York City, then inserted a clause allowing surplus capital to be used for "moneyed transactions." He had created a bank disguised as a utility. Hamilton, who had opposed the charter, was furious. He was shot five years later.

During the Panic of 1907, a stock market crash triggered a cascade of bank failures across the United States. J. Pierpont Morgan — then 70 years old — essentially acted as America's central bank, personally organising a coalition of bankers to inject liquidity into failing institutions. Morgan locked the country's leading bankers in his library and refused to let them leave until they agreed on a rescue plan. The episode directly led to the creation of the Federal Reserve in 1913.

When Bear Stearns collapsed in March 2008, JPMorgan CEO Jamie Dimon agreed to acquire it for $2 per share — later revised to $10 — in a deal orchestrated over a single weekend with the Federal Reserve. The deal was considered a rescue of the financial system. Six months later, JPMorgan acquired Washington Mutual in the largest bank failure in U.S. history. JPMorgan emerged from the 2008 financial crisis stronger than it entered.

When First Republic Bank failed in May 2023 — the second largest bank failure in U.S. history — JPMorgan acquired its assets in an FDIC-facilitated deal, gaining approximately $50 billion in deposits and $173 billion in loans. It was Dimon's third major crisis acquisition. Regulators described him as the most important banker of his generation. Critics asked whether JPMorgan had become too systemically important to ever be allowed to fail — or to be effectively regulated.

Jamie Dimon, who had run JPMorgan since 2005, spent 2025 delivering increasingly pointed warnings about geopolitical risk, U.S. fiscal deficits, and the dangers of complacency in financial markets. His annual shareholder letters had become must-reads in global finance, combining specific financial analysis with broad warnings about the state of the world. Dimon, then 69, began publicly preparing the market for his eventual departure, though no timeline was announced. JPMorgan's market capitalisation exceeded $700 billion, making it the largest bank in U.S. history by that measure.
