[넥스트포스트=황상욱 기자] The United States is stepping up support for its refining industry in the name of energy security, while South Korean retail investors are rapidly shifting money into U.S. stocks and artificial intelligence (AI)- and semiconductor-related assets. Washington is expanding policy support to protect its manufacturing and energy base, while investors are betting on high-growth technology stocks.

U.S. Energy Secretary Chris Wright said on the 17th that the government plans to unveil measures to support the U.S. refining industry within days.

Wright said U.S. refineries are operating at high utilization rates, but warned that some facilities could be shut down. He added that the government has discussed ways to expand production and keep existing facilities running with industry officials. The remarks suggest that Washington sees not only crude oil production but also refining capacity, which turns crude into gasoline and diesel, as a key part of energy security.
While the U.S. government moves to preserve supply chains in traditional industries, a different trend is emerging in financial markets. South Korean investors are increasingly pouring money into U.S. stocks, particularly in AI and semiconductors.

According to CNBC, South Korean investors bought a net $4.5 billion worth of U.S. stocks in July alone, equivalent to more than 6 trillion won.

One of the more unusual trends is that Korean investors are buying SK hynix through American depositary receipts (ADRs) in the U.S. market even though the company's shares are already traded in South Korea. Market participants overseas have described the pattern as unusual.

ADRs are securities that allow shares of foreign companies to trade in the U.S. market. They are generally used to make it easier for U.S. investors to buy foreign stocks. For Korean investors, however, buying U.S.-listed ADRs of a company they can already purchase at home may indicate that money is flowing not just into specific companies, but into the broader themes of the 'U.S. market' and 'AI.'

SK hynix is widely regarded as a major beneficiary of the expansion of the high-bandwidth memory (HBM) market. As investment in generative AI increases, demand for memory used in AI servers has also grown, drawing more investor attention to the company.

Still, a company's growth outlook and the price investors pay for its shares are separate issues. If buying spreads from ordinary shares to ADRs and leveraged products, stock prices could move faster than underlying earnings.

Two distinct capital flows are therefore emerging in the United States. The government is increasing support to preserve production capacity in traditional industries such as refining, while private money is moving toward growth sectors including AI and semiconductors.

The rise in South Korean purchases of U.S. stocks and growing demand for SK hynix-related ADRs reflect one side of this broader 'America rush.' But simply trading in the U.S. market does not create new investment value by itself, making it increasingly important for investors to examine corporate earnings, product structures and valuation levels together.
