Pet banks were state-chartered banks that the federal government deposited public money into, starting in the 1830s

A pet bank was a state bank chosen by the U.S. Treasury to hold federal government deposits. The term itself was never official — it was a nickname critics used, meant to be insulting. The idea was that these banks were the government's "pets," favored and fed with public money. The practice began in 1833 when President Andrew Jackson removed federal deposits from the Second Bank of the United States and spread them across multiple state banks instead.

This was not a small administrative choice. The federal government held millions of dollars. Deciding which banks got to hold that money was deciding which banks would grow wealthy and powerful. It also meant the federal government was no longer using a single national bank to manage its finances — a shift that created both opportunity and chaos in the American banking system.

Key Takeaways

  • Pet banks were state-chartered banks that held U.S. Treasury deposits starting in 1833, after President Andrew Jackson removed federal money from the Second Bank of the United States.
  • The federal government chose which state banks would receive deposits, giving those banks access to large sums of public money they could lend out for profit.
  • Pet banks were controversial because they mixed government money with private banking interests, and because the selection process was seen as politically motivated.
  • The pet bank system collapsed during the financial panic of 1837, when many of these banks failed and the government lost access to its deposits.
  • The system demonstrated why the federal government eventually created the Federal Reserve in 1913 to manage the nation's money supply independently.

Why Jackson created the pet bank system

Andrew Jackson believed the Second Bank of the United States had too much power. The Second Bank was a private corporation chartered by Congress, and it controlled the nation's money supply. Jackson saw it as a threat to democracy — a powerful institution answerable to wealthy shareholders rather than to voters. In 1832, Congress voted to renew the bank's charter, but Jackson vetoed it. He then ordered the Treasury to stop depositing federal money there.

The problem was that the federal government still needed somewhere to put its money. Jackson's solution was to distribute deposits across multiple state banks. The idea was that spreading the money around would prevent any single bank from becoming too powerful. Instead, it created a different problem: the federal government was now choosing winners and losers in the banking world, and those choices looked political.

How pet banks actually worked

When the Treasury deposited federal money into a pet bank, that bank could use the deposits to make loans. If the Treasury deposited $100,000, the bank could lend out most of that money and keep the interest as profit. The bank was supposed to keep enough cash on hand to return the money when the government asked for it, but there was no federal oversight to may support this happened.

The banks that received the largest deposits grew rapidly. They could lend more money, attract more customers, and expand their operations. Banks that were not chosen as pet banks fell behind. This gave the federal government enormous power over which banks succeeded and which struggled — power that came from political connections rather than banking skill or stability.

The system also encouraged reckless lending. Because banks knew they had access to large federal deposits, they took bigger risks. They made loans to speculators buying western land, to canal companies, and to other ventures that might not have been sound investments. As long as the federal deposits kept coming, the banks could cover losses.

The political controversy around pet banks

Critics argued that the pet bank system was corrupt. Banks that supported Jackson's political party received deposits. Banks that opposed him were left out. The selection process was not transparent, and there was no clear standard for which banks deserved federal money. Opponents called them "pet banks" to suggest they were Jackson's personal favorites, chosen for loyalty rather than competence.

The controversy was not just about fairness. It was about the proper role of government. Should the federal government use its money to reward political allies? Should public funds be mixed with private banking interests? These questions divided the country and contributed to the rise of the Whig Party, which opposed Jackson's policies.

The collapse of the pet bank system

The pet bank system fell apart during the Panic of 1837, a severe financial crisis that began shortly after Jackson left office. Many of the pet banks had made risky loans and did not have enough cash to meet withdrawals. Banks failed, and the federal government lost access to millions of dollars in deposits. The crisis demonstrated that spreading federal money across weak state banks was not a solution — it was a recipe for disaster.

The panic also showed that the United States needed a more stable way to manage its money supply. State banks could not be trusted to act in the national interest. The federal government needed an institution that was independent from politics and strong enough to prevent financial crises.

How pet banks led to the Federal Reserve

The failure of the pet bank system was one reason the United States eventually created the Federal Reserve in 1913. The Federal Reserve is a central bank — similar in some ways to the Second Bank that Jackson had destroyed, but with a different structure. It is run by a board of governors appointed by the president and confirmed by the Senate, and it operates with more independence from day-to-day politics than the pet banks ever had.

The Federal Reserve's job is to manage the nation's money supply, set interest rates, and prevent financial crises. It does not choose which private banks get federal deposits based on politics. Instead, it works with all banks equally and tries to keep the entire banking system stable. The pet bank system taught the country that this kind of neutral, professional management was necessary.

Pet banks versus modern banking

Today, the federal government does not deposit money in private banks the way it did with pet banks. Instead, the Treasury maintains accounts at the Federal Reserve, and the Federal Reserve manages the government's money. Private banks can borrow from the Federal Reserve if they need cash, but they do not receive special treatment based on politics.

Modern banks are also regulated much more heavily than pet banks were. The Federal Deposit Insurance Corporation (FDIC) insures deposits so that if a bank fails, customers do not lose their money. Banks must maintain certain levels of cash reserves and follow rules about what kinds of loans they can make. These regulations exist partly because of lessons learned from the pet bank era, when weak banks failed and took public money with them.

Frequently Asked Questions

Why did Jackson hate the Second Bank of the United States?

Jackson believed the Second Bank was too powerful and served wealthy shareholders rather than ordinary Americans. He saw it as a threat to democracy and wanted to break its control over the nation's money supply. His supporters called it the "Monster Bank."

Did pet banks actually help the economy?

In the short term, they increased lending and economic activity. But they also encouraged reckless loans and speculation. The system collapsed in 1837, causing a severe financial crisis that hurt the economy far more than any short-term gains.

How many pet banks were there?

The number varied over time, but at its peak the Treasury had deposits in dozens of state banks across the country. There was no fixed number — the Treasury added and removed banks based on political and financial considerations.

Could the pet bank system happen again today?

No. The Federal Reserve now manages federal deposits, and banking regulations prevent the kind of political favoritism that characterized the pet bank era. Banks are also insured by the FDIC, so a bank failure would not cause the government to lose deposits the way it did in 1837.

What happened to the money the government lost when pet banks failed?

Much of it was straightforward gone. The banks had lent it out or lost it on bad investments. The government had no insurance and no way to recover the funds. This was one reason Congress later created the FDIC and other protections for deposits.
