Working paper: Mortgage choice and expenditure over the lifecycle: evidence from expiring interest-only loans
Working paper - January 2020 - No. 150
We study how homeowners’ consumption responds to the beginning of the amortization period on interest-only mortgages. In response to an average increase in mortgage instalments worth 9 per cent of annual income, consumption drops by 3 percent of income, in the year when amortization starts. This expenditure cut is persistent, but only affects a small subset of borrowers with high leverage ratios. These borrowers might have been unable to rollover their interest-only loans into new ones.
