Which regulation sets limitations on interbank liabilities?

The regulation that sets limitations on interbank liabilities is Regulation F. This regulation is specifically designed to address the limitations and conditions under which banks can engage in transactions with each other. Regulation F is particularly important as it aims to prevent excessive risk accumulation among financial institutions by imposing restrictions on the level of exposures that one bank can have to another. This helps to maintain overall financial stability and reduces the likelihood of contagion within the banking system.

In contrast, Regulation E pertains to electronic funds transfers and consumer protections related to those transactions, while Regulation D focuses on the reserve requirements for depository institutions and does not directly govern interbank liabilities. Regulation J is related to the collection of checks and funds and also does not address interbank liabilities specifically. Understanding the focus and purpose of each regulation clarifies why Regulation F is the correct answer in the context of limitations on interbank liabilities.
