South Korea's household lending by banks rose at the fastest rate in five months in April on increased credit loans. 

According to the banking industry on Thursday, outstanding household loans by the nation's five main lenders came to 538-point-four trillion won as of the end of April. 

The total marked a three-point-six trillion won increase from a month earlier, the largest on-month growth since November last year, when it increased by over four trillion won. 

The rise is attributed to a sharp growth in personal credit loans, which are estimated to have increased due to the government’s tightening of mortgage regulations. 

Outstanding credit loans reached 99-point-seven trillion won last month, up one-point-one trillion won from a month earlier. It's the first time since last November that the monthly growth surpassed one trillion won.
