European stock markets are set to open sharply lower on Tuesday, June 23, 2026, as a global selloff in technology shares sweeps in from Asia. Futures tied to the region’s main indexes were pointing down more than 1% before the open, after the Korea Exchange was forced to halt trading earlier in the day when South Korea’s Kospi index plunged as much as 9%. The selling that started in chip stocks overnight is now rolling toward Frankfurt, Paris, and London.

The trigger is the same worry rattling markets worldwide: that this year’s enormous run-up in artificial intelligence and semiconductor stocks has climbed too far, too fast. When investors decide to lock in profits all at once, the selling tends to hit hardest the bets that the most people had piled into — and few have been more popular in 2026 than chips.

The damage across Asia set the tone. A broad gauge of Asian stocks dropped 3.4%, Japan’s Nikkei 225 slipped 0.6% and the Topix fell 0.5%, both pulling back from record highs. In the US, futures pointed lower too, with S&P 500 contracts off more than 1% and Nasdaq 100 futures down about 2%. The MSCI All Country World Index, the widest measure of global stocks, fell 0.6%.

Europe’s own chip and tech names are likely to bear the brunt. The Netherlands’ ASML, the world’s most important supplier of chipmaking machines, along with Germany’s Infineon Technologies, France’s STMicroelectronics, and software giant SAP, tend to move in lockstep with the global semiconductor trade. When chip stocks fall in Asia and the US, these European heavyweights usually follow at the open.

Adding to the unease, the Japanese yen sank toward its weakest level in 40 years, trading around 161.5 per dollar. The slide reflects a widening gap between the US Federal Reserve, where Chair Kevin Warsh has signaled rates could rise again this year, and the Bank of Japan, which has moved far more slowly. The dollar index, which measures the greenback against major currencies, sits near a one-year high, up about 3% in 2026. A strong dollar and rising US rate expectations tend to pull money out of riskier assets everywhere, European stocks included.

For European exporters, a stronger dollar is not all bad — it makes their goods cheaper for American buyers. But the broader signal of climbing US rates usually weighs on share prices across the board, especially the high-priced tech names that have led the market higher.

One bright spot is energy. Mediators Qatar and Pakistan said the US and Iran have agreed on a roadmap toward a final deal within 60 days, and Washington granted Tehran a 60-day license to sell oil abroad. That pushed oil prices down nearly 2%, with Brent crude near $79 a barrel — welcome news for fuel-hungry European economies, even as Iran’s announced closure of the Strait of Hormuz keeps some risk in the picture.

Not every corner of the European market is likely to suffer. On past selloff days, defensive sectors such as utilities, healthcare, and consumer staples have held up better than tech, and falling oil prices tend to help airlines and other heavy fuel users. Defense stocks, a standout performer in Europe this year, have also shown they can buck broad declines.

The bigger question for European investors is whether Tuesday marks a brief stumble or the start of a deeper cooldown in the AI trade. The companies at the center of the selloff are still reporting strong demand for their chips, and Europe’s main indexes have spent much of 2026 near record highs. A single rough open does not undo that. But the speed of the drop is a reminder of how quickly money can rush for the exits when a popular trade turns.

Traders will now watch how Wall Street opens later Tuesday and whether the selling in chips slows. If US tech steadies, Europe’s losses could prove shallow. If it does not, the pullback that began in Seoul and Tokyo may have further to run.
