On Monday, semiconductor stocks saw a dramatic decline, plummeting 4.8%, which contributed to the Nasdaq dropping 1.5%. This downturn was reflected in other major U.S. indices, with the S&P 500 losing 0.8% and the Dow Jones Industrial Average losing 138 points, about 0.3%. The Philadelphia Semiconductor Index led this selloff, highlighting the fragility of the sector.

Impact of South Korean Market on U.S. Stocks

The catalyst for the U.S. semiconductor drop was a nearly 9% crash in South Korea’s KOSPI index, triggering concerns among investors globally. As a result, trading on the Korea Exchange was interrupted when the index plunged over 5% during the session. Notably, the American Depositary Receipts (ADRs) for South Korean chip manufacturer SK Hynix began trading on the same day but stumbled, experiencing a drop exceeding 9% in its debut. Before this drop, memory semiconductor stocks had been some of the most advantageous performers of 2026.

Effects on Cryptocurrency Market

The selloff in semiconductor stocks pressured the digital currency market as well. Bitcoin fell over 2% and was trading near $62,380, responding to increasing market expectations for a potential Federal Reserve interest rate hike of 50% in July. This expectation represents a substantial shift from the previous 10% estimate.

Alongside Bitcoin, major cryptocurrencies like Ether and XRP also experienced losses. This correlation between tech stocks and digital assets indicates the intertwined nature of today's financial markets.

Broader Market Stability Outside Technology

Excluding technology stocks, the market showed a more stable environment. The ProShares S&P 500 Ex-Technology ETF ended trading nearly unchanged, highlighting that the volatility was concentrated within the tech sector. As the semiconductor and tech markets face these pressures, investors are closely monitoring upcoming economic indicators, especially the Consumer Price Index data due to be released shortly.
