Involves

Idea

The safety net changes the calculation

Suppose a lender receives the upside of a risky loan but expects someone else to absorb much of the downside. A loan that previously looked unattractive can begin to look worthwhile. The project's underlying risk has not improved. The lender's exposure to it has changed.

Deposit insurance creates a related tension. It protects covered depositors when a bank fails and reduces their reason to rush for the exit. But those depositors also have less reason to investigate the bank's risk-taking. Supervision and capital requirements help address the incentive problem that accompanies the protection.

Protection changes behavior before anyone makes a claim.

Ask who chooses the risk and who pays when it goes wrong.

Where it breaks down

Moral hazard does not show that insurance is a mistake. A system without protection has its own costs, including destructive runs. Nor does the concept prove a particular banker took excessive risk. That requires evidence about actual behavior.

How it connects

Bank guarantees show why protection and oversight often need to travel together.

Why can insurance increase the importance of supervision?

Protected depositors have less incentive to monitor bank risk. Exactly. Protection reduces one source of market discipline, so other safeguards matter more.

What the sources establish

  • Deposit insurance can reduce depositor monitoring and create a role for supervisory safeguards.
