A bank run is when many customers withdraw money from a bank at the same time because they think the bank may fail. In Intro to Business, it shows how fear, cash reserves, and deposit insurance affect banking stability.
A bank run in Intro to Business is a sudden rush of customers trying to pull their deposits out of a bank because they think the bank might not be able to pay everyone back. The problem is not just that people want their money, it is that the fear itself can make the bank unable to meet everyone’s withdrawals at once.
Banks do not keep every deposited dollar sitting in cash. Under fractional reserve banking, a bank lends out much of the money it takes in and keeps only part of it in reserve. That is normal business practice, but it means a bank cannot instantly hand back every deposit if everyone shows up at once.
A bank run often starts with rumors, bad financial news, or a wider economic downturn. Even customers who never planned to panic may join in once they see lines forming at the branch or hear that others are withdrawing. That is why a bank run can turn fear into a real financial crisis.
In the business world, this is a classic example of how confidence affects financial institutions. A bank can be solvent on paper, meaning its assets are still worth more than its liabilities, but still run out of cash if too many people demand withdrawals immediately. So a bank run is partly a liquidity problem, not always a simple “the bank is broke” problem.
That is also why governments created deposit insurance like FDIC coverage. If customers know their deposits are protected up to a limit, they are less likely to rush to the bank over rumors alone. The goal is to keep normal banking behavior from turning into a panic that spreads to other banks too.
Bank run matters in Intro to Business because it connects banking, risk, and consumer confidence in one real-world situation. If you are studying finance or banking, this term explains why banks need reserves, why regulation exists, and why trust is a huge part of the financial system.
It also ties directly to deposit insurance and the FDIC. Those protections are not just background facts, they are a response to the exact problem a bank run creates. When a bank run happens, the business issue is not only how much money the bank has, but whether customers believe their money is safe.
This term shows up again when you talk about systemic risk. One bank’s trouble can spread fear to other banks, which is why bank runs can become bank panics. In a class discussion or case study, you can use the term to explain how a small confidence problem turns into a much bigger market problem.
It also helps you read business news more carefully. If a headline says a bank is facing withdrawal pressure, you can tell whether the issue is liquidity, solvency, or public confidence, instead of treating all bank failures the same way.

Deposit insurance is one of the main tools used to reduce the chance of a bank run. If customers know their deposits are protected up to a limit, they are less likely to panic just because they hear rumors. In Intro to Business, this connection shows how policy can stabilize consumer behavior.
Fractional Reserve Banking
Bank runs make more sense once you understand fractional reserve banking. Because banks lend out much of the money they receive, they cannot keep every deposit available as cash. That setup is efficient for lending and business growth, but it also leaves banks vulnerable if too many people withdraw at once.
Bank Panic
A bank run can spread into a bank panic when fear moves beyond one institution. Instead of just one bank facing withdrawals, customers start doubting the whole banking system. This is the bigger picture version of the same problem, and it is why confidence matters so much in finance.
Federal Deposit Insurance Corporation
The FDIC is the agency most students connect with bank runs in the United States. It insures deposits and helps restore trust when banks fail. In a business course, it is the concrete example of how government backing can calm depositors and keep a small problem from becoming a wider collapse.
A quiz question on a bank run usually asks you to identify the cause or the effect of mass withdrawals. You might also get a short case about rumors at a bank and need to explain why the bank can fail even if it owns valuable loans and assets.
On problem sets or class discussions, use the term to trace the chain reaction: fear, withdrawals, depleted reserves, and possible failure. If the prompt mentions FDIC protection, connect that directly to restoring confidence and reducing panic. If the prompt brings up fractional reserve banking, explain why banks are not built to pay out every deposit at once.
A bank run usually starts at one bank, where customers rush to withdraw their own deposits. A bank panic is broader, when fear spreads through the financial system and many banks face withdrawal pressure at the same time. Think of a bank run as the trigger and a bank panic as the wider outbreak.
A bank run happens when lots of customers withdraw money at the same time because they fear the bank may fail.
The problem is partly about liquidity, since banks do not keep all deposits in cash under fractional reserve banking.
Rumors, bad economic news, or a loss of confidence can turn fear into real financial trouble.
Deposit insurance like FDIC coverage exists to stop panic by making depositors feel safer.
In business, bank runs show how trust can affect the entire banking system, not just one bank.
A bank run is when many customers withdraw their deposits at the same time because they think the bank might fail. In Intro to Business, it is a core example of how confidence and liquidity affect banks. The bank may not be insolvent at first, but the rush for cash can force it into trouble.
Bank runs usually start with fear, rumors, or signs that a bank may be in trouble. Once people believe others are withdrawing, they may rush to protect their own money. That crowd behavior can create the very failure everyone was trying to avoid.
Deposit insurance makes customers more confident that their money is protected if the bank fails, up to a set limit. That lowers the urge to panic and withdraw immediately. It is one of the biggest safeguards in the U.S. banking system.
No. A bank run is the rush of withdrawals, while bank failure is the result if the bank cannot survive the pressure. Sometimes a bank is actually solvent but still collapses because it runs out of cash fast enough to meet withdrawals. That is why bank runs are so dangerous.
