  • Korean Financial Regulators Advance Legislation to Introduce Regulatory Sandbox to Spark FinTech

    The 2018 year in review in Korea was notable for the sluggish overall economy, uncertainty surrounding the geo-politics and impact on Korea due to the global trade wars, on-going concerns related to the lack of jobs and unemployment, increased taxes and burdens for businesses and families, and no meaningful improvement or clarity in the current situation for 2019. In response, the Korean National Assembly passed a legislation called the Financial Innovation Support Act (the “FinISA”) on December 7, 2018 to spark the financial services industry in conjunction with FinTech products and services. The FinISA, which will soon take effect in March 2019, is intended to lay the legal foundation to introduce a regulatory sandbox for innovative financial services, where FinTech firms test their new products and services without certain regulatory oversight pursuant to exemptions for a limited period of time (“Sandbox”). As the FinISA exempts or defers application of existing finance-related regulations for new financial technology, products or services with the purpose of fostering the creation of innovative and new financial products and services, it will also support the stabilization of such services in the financial services market at the end of the testing period and is expected that the FinISA will support a revitalization of the FinTech industry which experienced sluggish growth in recent times. In particular, as companies and investors become more interested in security tokens and Security Token Offerings (“STO”) which are regulated by the Financial Investment Services and Capital Markets Act (the “FSCMA”), there have been on-going discussions and debates as to whether the FinISA could lead to a breakthrough in the crypto-asset industry based on blockchain technology. Crypto assets encompasses those assets which utilize blockchain technology where the asset is digitalized by utilization of cryptography, peer-to-peer networks and a public ledger of verified transactions resulting in a ‘units’ of such a crypto asset without any involvement by middle-persons or brokers (e.g., cryptocurrency.
