South Korea's household debt increased at the world's second fastest pace in the first half of this year.

According to a report by the Bank for International Settlements (BIS) released on Sunday, the country's household debt-to-GDP ratio came to 93-point-eight percent at the end of June, up one percentage point from six months earlier.

The nation has stayed at eight in the rankings of the ratio since 2015, but the growth of the ratio is the second largest among 43 major countries in the first half of the year, only after China which posted a gain of two-point-four percentage points.

The country's on-year growth in the ratio steadily increased over the past five years, from one-point-one percentage point in 2012, one-point-nine percentage points in 2014 and four-point-seven percentage points in 2016.
