To prevent the formation of dangerous asset bubbles in real estate markets, central banks and macroprudential authorities enforce dynamic lending constraints on commercial banking portfolios.
Key Macroprudential Lending Boundaries
- Loan-to-Value (LTV) Caps: Limits the maximum size of a mortgage loan relative to the appraised value of the underlying property. An LTV cap of 80% requires the buyer to provide a 20% cash down payment, limiting risk exposure for the lender.
- Debt-to-Income (DTI) Limits: Restricts total mortgage sizes based on the borrower’s verified annual income. This measure prevents households from overextending themselves during low interest rate environments.

LTV Frameworks | Limits leverage on asset values| Restricts credit loss size if defaults spike
DTI Restraints | Ties credit size to income levels| Reduces overall househ
