Household loans extended by banks rose at the fastest pace in nearly two years in May as lending linked to stock investment grew amid a market rally, data showed Thursday.

Outstanding household loans by banks grew 6.9 trillion won ($4.5 billion) to 1,181.8 trillion won last month, accelerating from the previous month's 2.1 trillion-won rise, according to data by the Bank of Korea (BOK).

It marked the sharpest on-month growth since August 2024, when household loans increased 9.2 trillion won from a month earlier.

Mortgage loans increased 3.2 trillion won on-month in May, up from a 2.7 trillion-won gain in April.
