Korea has faced the task of economic recovery of creditors due to the IMF economic crisis and credit card crisis. This situation occurred that new system of using dormant deposits was introduced in 2007, ten years before Japan in 2016.

In Korea, dormant deposits are mainly utilized to credit loans for low-income individuals, while Japan is focused on supporting private public interest organizations which engaged in public interest activities for local residents, including vulnerable groups. From the viewpoint of SDGs, which emphasize the vulnerabilities are not only due to economic problem, but also due to social problems, it means a lot to Korea, which is using dormant deposits mainly to credit loans for low-income individuals, partially for social enterprise and cooperative which provides social support.
