Bank of America was founded in 1904 by Amadeo Giannini as the Bank of Italy

Amadeo Giannini, an Italian immigrant who arrived in San Francisco in 1889, opened the Bank of Italy on October 17, 1904, in the North Beach neighbourhood. Giannini was not a banker by training—he was a produce merchant and had worked in his stepfather's commission business. He saw an opportunity: the Italian immigrant community in San Francisco had nowhere to borrow money. Banks at the time served only wealthy merchants and large businesses. Giannini decided to lend to working people—labourers, fishermen, small shopkeepers—at reasonable rates.

The bank's first office was a single room with a desk, a safe, and a telephone. Giannini's initial capital came from his own savings and from a small group of investors, mostly Italian merchants. The bank opened with around $8,500 in deposits. Within a year, it had grown enough that Giannini hired his first employee. By 1906, the Bank of Italy had three locations.

The 1906 San Francisco earthquake tested the young bank's survival. While other banks closed their vaults and refused to lend, Giannini loaded gold into a cart and moved through the rubble, lending money to rebuild homes and businesses. This decision—to lend when others would not—became the foundation of the bank's reputation and its growth.

Key Takeaways

  • Amadeo Giannini founded the Bank of Italy in San Francisco in 1904 with the specific goal of lending to Italian immigrants and working people who other banks would not serve.
  • Giannini was a produce merchant, not a trained banker, and started the bank with his own savings and money from a small group of Italian merchants.
  • The bank's willingness to lend after the 1906 San Francisco earthquake, when other banks refused, established its reputation and accelerated its growth.
  • The Bank of Italy changed its name to Bank of America in 1930 and eventually became the largest bank in the United States through expansion and mergers.

How the Bank of Italy became Bank of America

The Bank of Italy grew steadily through the 1910s and 1920s. By 1918, it had become the largest bank in California by deposits. Giannini began opening branches throughout California—a practice that was unusual at the time, when most banks operated only in a single location. He also pioneered the use of branch banking to serve rural areas and small towns.

In 1928, Giannini merged the Bank of Italy with the Bank of America, a smaller bank that had been operating in Los Angeles. The combined institution took the name Bank of America. This was a strategic move: the Bank of America name had broader appeal than Bank of Italy, especially as Giannini wanted to expand beyond the Italian immigrant community and serve all Californians.

By 1930, Bank of America had become the largest bank in California. Giannini continued to expand through the 1930s, even during the Great Depression, when many banks failed. His willingness to lend during economic downturns—the same instinct that had driven him during the 1906 earthquake—kept the bank solvent and growing while competitors collapsed.

Giannini's banking philosophy and its lasting impact

Giannini believed that banking should serve ordinary people, not just the wealthy. He introduced several practices that were revolutionary at the time: small personal loans, mortgages for working families, and banking hours that accommodated people who worked during the day. He also paid attention to customer service in a way that larger banks did not. Bank of America employees were trained to know customers by name and to understand their financial situations.

Giannini stepped back from day-to-day management in the 1930s but remained involved in strategy. He retired in 1945 and died in 1949. His successors continued his expansion strategy, and by the 1960s, Bank of America had become the largest bank in the United States by deposits. The bank's growth accelerated further after deregulation in the 1980s and 1990s, and it expanded nationally through acquisitions.

The core principle Giannini established—that a bank should serve a broad customer base, not just the wealthy—remains part of Bank of America's stated mission today, though the bank's scale and structure have changed dramatically since his time.

The early years: 1904 to 1920

In its first decade, the Bank of Italy operated in a competitive landscape dominated by larger, established banks. Giannini's advantage was not capital or connections—he had neither—but a clear understanding of an underserved market. Italian immigrants in San Francisco needed credit to buy homes, start businesses, and weather economic downturns. Traditional banks saw them as too risky.

Giannini's lending decisions were based on character and reputation, not collateral. He would lend to a fisherman or a construction worker if he believed the person was honest and hardworking, even if they had no property to pledge. This approach built loyalty and also proved sound: default rates on Bank of Italy loans were lower than at competing banks, because borrowers understood that Giannini had taken a personal risk on them.

By 1920, the Bank of Italy had expanded beyond North Beach and was opening branches in other San Francisco neighbourhoods and in nearby towns. The bank had also begun to serve customers beyond the Italian community, though Italian immigrants remained its core base.

Expansion across California and beyond

After 1920, Giannini's strategy shifted toward statewide expansion. He opened branches in Los Angeles, San Diego, and Sacramento. This was a deliberate move to build a network that could serve customers across California, not just in San Francisco. At the time, most banks were restricted by law to a single location. Giannini worked with California regulators to establish the legal framework for branch banking, which eventually became standard practice nationwide.

The 1928 merger with the Los Angeles-based Bank of America was the pivotal moment. It gave Giannini a foothold in Southern California and a name with broader geographic appeal. After the merger, the combined bank had over 400 branches across California—an enormous network for the time.

The Great Depression tested the bank's stability. Many banks failed between 1929 and 1933 because they had invested heavily in stocks or made risky loans. Bank of America, under Giannini's conservative leadership, had avoided these pitfalls. The bank remained solvent and continued to lend, which allowed it to gain market share as competitors failed.

Giannini's legacy and the bank's later history

Amadeo Giannini died on June 3, 1949, at age 79. By that time, Bank of America had become a national institution. His successors—first Lawrence Mario Rossi, then S. Clark Beise, and later A. P. Giannini Jr. (his son)—continued his expansion strategy but also modernized the bank's operations. They introduced automated teller machines, credit cards, and other innovations that made banking more convenient for ordinary customers.

The bank's growth accelerated dramatically after the 1980s, when federal deregulation allowed banks to operate across state lines and to merge with other financial institutions. Bank of America acquired smaller regional banks throughout the 1990s and 2000s, and by the 2008 financial crisis, it had become the second-largest bank in the United States by assets (after JPMorgan Chase).

Today, Bank of America operates thousands of branches and serves millions of customers worldwide. The bank's origins as a lender to working people remain part of its public identity, though its scale and complexity are vastly different from Giannini's one-room office in North Beach.

When did the Bank of Italy change its name to Bank of America?

The name change happened in 1930, after the 1928 merger with the Los Angeles-based Bank of America. Giannini chose the new name because it had broader geographic appeal and better reflected his goal of serving all Californians, not just Italian immigrants.

Is Bank of America still based in San Francisco?

Bank of America's headquarters moved from San Francisco to Charlotte, North Carolina, in 1993. The bank still operates branches in San Francisco and throughout California, but its main operations are now based on the East Coast.
