Bank of England measures 'insure against housing boom'
26 June 2014 Last updated at 21:17 BST
Plans by the Bank of England to cap riskier mortgage lending have been hailed as an important "insurance policy" for the UK economy.
Under the proposal, lenders would not be allowed to lend any more than 15% of residential mortgages at more than four and a half times a borrower's income.
Banks and building societies will also now have to check that you could still pay it back if interest rates went up by 3%.
The move will have little initial short-term impact on people's chances of getting a home loan, but commentators have said the measure could have "bite" in the future.
