Assessing the impact of macroprudential measures

This Letter attempts to assess the potential impact of implementing the recently proposed proportionate loan-to-value ratio on the wider housing market. Using a dual micro and macro simulation strategy, we find evidence for some moderate negative impacts of the LTV cap on house prices and mortgage interest rates, with a proportionately larger impact on housing supply. These can, however, be considered to be close to the maximum possible impacts given the conservative assumptions and empirical strategies underlying our analysis.
