The Irish Central Bank is scheduled to introduce new macro-prudential risk controls on Irish mortgage lending, with the new regulations taking effect on January 1st or soon thereafter. One of the regulations will limit most new mortgages to an initial loan-to-value ratio of 80% or less. There has been considerable discussion of the effect of loan-to-value limits on potential property purchasers, but the analysis has been very poorly framed.
The budgeting scenario has been described as follows:
“Consider a couple who wish to purchase a €300,000 property. With a LTV limit of 80% this will require that they save €60,000 for the down payment whereas if they were allowed to borrow 85% they would only need savings of €45,000.”
This oft-repeated budgeting scenario misrepresents the nature of market-wide LTV limits imposed by the Central Bank. This budgeting scenario gives the impression that the policy decision is about imposing/not imposing the LTV constraint on only one particular buyer rather than market-wide. It misses the large compositional effects since leveraged property buyers compete with one another for properties. The degree of leverage allowed in the banking system feeds into property prices, and this affects the opportunity set of purchasers.
