30-year U.S. Treasury yield hits a ceiling, and the high valuation logic of tech stocks is undergoing the most rigorous stress test—cost of capital is the ultimate judge.

ME News 16 reports that while technology stocks and AI stocks soar, rising bond yields may cause the stock market to deviate from its trajectory. If the 30-year U.S. Treasury yield remains above 5%, AI stocks will face pressure. Several executives say that the long-term U.S. bond yield is a key intersection for AI capital expenditure and private lending costs, which could increase government financing costs and negatively impact residents' wealth; despite optimistic market sentiment, interest rates are still climbing, and if yields continue to rise, the market will face a reality check.
