Ireland's central bank wants to avoid any repeat of the reckless lending and lax regulation that led to a devastating property crash six years ago, and has proposed the limits as prices recover quickly amid a lack of supply in urban areas.

The measures would require banks to restrict lending above 80 percent of the value of a home to no more than 15 percent of the aggregate value of all housing loans, while also limiting lending in excess of 3.5 times a borrower's gross income.

In its official response to the proposals on Tuesday, the finance ministry said such a loan-to-value (LTV) limit would be unduly restrictive and have implications for the distribution of home ownership. First-time buyers especially would find it more difficult or "even impossible" to save a deposit while also paying high rents.

"The primary balance to be struck is to ensure that measures put in place to protect financial stability will not have an undue negative impact on sustainable economic recovery or have unintended social impacts," the ministry said.

"There is, therefore, a strong case to be made to the Central Bank in adopting a more nuanced and graduated approach to the introduction of new macro prudential measures."

It suggested that a graduated approach could be achieved by initially adopting a 90 percent LTV target which would be reduced over a period of time. A higher threshold exemption of perhaps 25 percent of new lending might also first be adopted.

The ministry also urged that the new rules be phased in.

Ireland's banks have previously called on the central bank to scale back the proposals, warning that they would price first-time buyers out of the market.

The central bank said it had received over 150 responses to its consultation paper by Monday's deadline and that it expected the final measures to come into effect early next year.
