Asia-Pacific markets tumbled on May 15, 2026, as high-stakes US-China trade talks between President Donald Trump and President Xi Jinping entered a second day.

Live News
Investors across the Asia-Pacific region reacted with caution as the second day of marathon negotiations between U.S. President Donald Trump and Chinese President Xi Jinping unfolded amid renewed trade tensions. South Korea’s benchmark Kospi index experienced a sharp decline, falling over 6% from its recent all-time high, marking one of its worst single-day drops in recent months.
The sell-off was concentrated in major technology names, including semiconductor and electronics heavyweights that have driven the index’s rally earlier in the year. Analysts suggested that market participants are pricing in a potential breakdown in trade talks, which could disrupt global supply chains and dampen demand for South Korean exports. Heavyweight stocks such as Samsung Electronics and SK Hynix were among the biggest drags on the index.
Other Asia-Pacific markets also fell. Japan’s Nikkei 225 and Hong Kong’s Hang Seng Index both declined, tracking the negative sentiment from the ongoing US-China dialogue. The moves came as traders digested mixed signals from the negotiations, with no clear resolution yet announced. Currency markets also saw volatility, with the South Korean won weakening against the U.S. dollar.
The Kospi’s drop from its record high underscores the vulnerability of export-reliant economies to geopolitical uncertainty. The index had surged in recent weeks on optimism over a potential trade deal, but the current retreat highlights the fragility of market sentiment.

Expert Insights
Professional market observers note that the Kospi’s sharp pullback from its record high may signal a period of heightened volatility as trade negotiations remain unresolved. The sell-off in heavyweight tech names, which had been the primary drivers of the index’s recent gains, suggests that investors are reassessing valuation risks amid geopolitical uncertainty.
“The market has been pricing in an ideal outcome from the Trump-Xi talks, but the second-day negotiations indicate that issues remain complex,” said one regional strategist, who spoke on condition of anonymity. “The Kospi’s drop of over 6% from its peak is a reminder that trade-dependent markets can turn quickly when the news flow shifts.”
Investment implications are multifaceted. South Korean exporters, particularly in the semiconductor and electronics sectors, could face headwinds if trade barriers are raised or if demand from China weakens. Conversely, a successful resolution could reignite the rally, but the current environment suggests caution.
Investors may want to monitor currency fluctuations and corporate earnings guidance for signs of impact. The won’s depreciation could benefit exporters but increase input costs for companies reliant on imported materials. Overall, the market’s reaction underscores the importance of geopolitical risk in portfolio allocation for Asia-Pacific equities.
