On the 24th (Korean time), the U.S. New York stock market closed lower across the board. As rising international oil prices and a surge in U.S. Treasury yields occurred simultaneously, selling emerged centered on technology stocks, which had recently shown strength.

■ Nasdaq Falls 1.13%... Russell 2000 Plunges by High 1% Range

The Dow Jones Industrial Average of 30 stocks finished the session at 51,511.59, down 352.10 points (0.68%) from the previous trading day. The Standard & Poor's (S&P) 500 index recorded 7,706.39, down 58.25 points (0.75%). It rose as high as 7,761.94 during the session but failed to hold its gains, at one point slipping to 7,694.89.

The tech-heavy Nasdaq Composite closed at 26,936.04, down 308.24 points (1.13%). Its intraday high was 27,217.33 and its low was 26,873.54. Small- and mid-cap stocks also fell sharply. The Russell 2000 index dropped by the high 1% range, coming under relatively stronger pressure than large-cap stocks.

■ Key Variable: Treasury Yields... 10-Year Yield Reaches Highest Level Since 2007

One of the key variables weighing on the market was Treasury yields. According to Reuters, U.S. Treasury yields rose, with the 10-year yield climbing to its highest level since 2007. Higher interest rates raise the discount rate applied to future earnings, which can weigh on the valuations of growth and technology stocks.

■ Oil Prices Surge About 4%... Iran Geopolitical Risk Resurfaces

Oil price movements also pressured investor sentiment. As geopolitical tensions surrounding Iran came back into focus, international oil prices rose, and wariness grew that higher energy prices could reignite inflationary pressures. Reuters reported that oil prices rose about 4% on the day, and the energy sector actually showed strength.

In particular, Iranian President Masoud Pezeshkian's statement in his U.N. speech that Iran would not yield to U.S. pressure also heightened market caution. Following President Trump's hardline remarks the previous day, tensions between the United States and Iran have once again emerged as a market variable.

■ Profit-Taking on AI and Big Tech... Alphabet and Amazon Decline

Profit-taking pressure also appeared in AI and major technology stocks, which had recently led the New York market. Reuters reported that declines in Alphabet, Amazon, and others weighed on the indexes. With the Nasdaq having traded near record highs and showing strong momentum through the previous day, the simultaneous jump in yields and oil prices expanded volatility, centered on technology stocks.

Accordingly, on the 23rd, the Dow, S&P 500, Nasdaq, and Russell 2000 all declined in the New York market. Market attention is turning once again to U.S. Treasury yields, international oil prices, the possibility of further interest rate hikes by the Federal Reserve, and the Middle East situation surrounding the United States and Iran.
