The correct answer is C.\n\nAdvising the insurance agency to adjust the premiums required, reflecting the individual risk profile of each bank, is the most effective strategy to curb moral hazards among banks. This approach, known as risk-based pricing, directly aligns the cost of insurance with the level of risk each bank takes on. Banks engaged in riskier activities would pay higher premiums, creating a direct financial disincentive for excessive risk-taking. In this way, banks internalize part of the cost of the risk they impose on the deposit insurance fund and on the broader financial system.\n\nChoice A is incorrect. While regulating executive compensation may address certain governance issues, it does not directly target the moral hazard arising from deposit insurance. Moral hazard specifically refers to changes in risk-taking behavior because a party is insulated from the consequences of that risk, not to compensation structures. Excessive compensation rules address agency problems, not insurance-induced risk-shifting.\n\nChoice B is incorrect. Requesting comprehensive information on each bank's financial transactions is useful for supervisory monitoring and early warning systems, but on its own it does not change the incentives of bank management to take on risk. Information gathering is a tool for risk identification, not a mechanism to deter risk-taking behavior. Without consequences tied to the information collected, moral hazard remains unaddressed.\n\nChoice D is incorrect. Encouraging deregulation would worsen moral hazard rather than curb it. Deregulation reduces oversight, weakens safeguards, and gives banks even more freedom to take on excessive risks, especially when they are already shielded by deposit insurance. This is the opposite of what is needed and would likely increase the probability of bank failures and systemic instability.\n\nKey Things to Remember:\n- Moral hazard occurs when a party insulated from risk behaves differently than it would if it were fully exposed to that risk. In banking, deposit insurance can lead banks to take on excessive risk because depositors (and the insurer) absorb the losses.\n- Risk-based premiums are the primary tool regulators use to mitigate this moral hazard, since they directly link the cost of insurance to the risk profile of each insured bank.\n- Other complementary mitigants include capital requirements, supervisory reviews, transparency requirements, and resolution frameworks.\n- Deposit insurance protects individual depositors but does not eliminate systemic risk; a triggering event in one major bank can still cascade through the financial system.
