Philip Lane says the rules could be tightened or relaxed as a result of his review
The Central Bank is due to review its new mortgage rules in the summer.
The regulations, introduced last September, have had a particular impact on first-time buyers.
They limit mortgage lending to three and a half times a person's salary and changed deposit rules, which has had a particular impact on first-time buyers, especially around Dublin.
Karl Deeter of Irish Mortgage Brokers told Newstalk's Breakfast the Central Bank may not make any changes to the rules when it carries out its assessment, but he says the rules have had an impact on the housing crisis:
