Data suggest that many South Koreans could find themselves under financial pressure if interest rates rise due to the unsecured loans they have in addition to their mortgages.
The Bank of Korea said Tuesday that 41.six percent of people who got new mortgages in the first quarter this year also had credit loans.
Some of the unsecured loans existed already, but others were taken out alongside the home loans.
The central bank said this ratio of mortgage borrowers who have other credit loans is the highest since data were first compiled in 2012.
They're especially vulnerable because, the BOK says, 80.4 percent of new borrowers had a variable rate on their mortgages and credit loans, which means their payments go up when rates rise.
