KakaoPay Securities said on Tuesday that the number of individual comprehensive asset management account (ISA) accounts had exceeded 100,000 as of Dec. 24.

The company said about 12,000 new accounts were opened a week on average since the product launched on Nov. 3 last year. Total deposited assets stood at about 72 billion won, rising 28.5 percent a week on average, it said.

Subscribers are evenly spread mainly among people in their 20s to 50s. It also cited an analysis that demand for long-term and diversified investment using tax-saving benefits is spreading across all age groups.

In the asset mix excluding cash balances, exchange-traded funds (ETFs) accounted for about 80 percent. The company said the tax-saving effect was larger than for regular stock accounts and that a preference for high-dividend products stood out.

It plans to expand wealth management services by strengthening content on tax-saving benefits and its function for suggesting stocks, and by pursuing links with pension savings. Over the longer term, it is also reviewing ways to integrate artificial intelligence (AI)-based investment support services into ISAs.

KakaoPay Securities said, "Brokerage ISAs are a fiercely competitive market because only 1 account per person is allowed," adding, "Recording these results even in such an environment is a figure that shows our presence in the market."
