Global equities reversed from record highs following news of fresh US strikes and sanctions on Iran, according to Deutsche Bank’s Jim Reid [1]. The S&P 500 and Nasdaq had achieved marginal gains in the previous session, with the S&P 500 rising by 0.02% and the Nasdaq by 0.07%, both reaching new record highs. The Dow also hit an all-time high, marking the first time in 2026 that all three indices achieved this simultaneously [1]. European benchmarks were trading near records as well, but the market tone shifted as futures and Asian markets weakened in response to the geopolitical developments [1].
US Treasury yields rose by 4 to 4.5 basis points across the curve, with the 10-year yield at 4.53% after a five-day rally, reflecting increased risk aversion and a rally in oil prices [1]. S&P 500 futures were down 0.37% and Nasdaq futures fell 0.80% following the news. In Asia, the KOSPI was the largest underperformer, dropping 3.61%, while the Hang Seng fell 2.12% and the Nikkei declined 1.34%, with technology shares particularly weak [1].
Prior to the sell-off, equities had shown mixed performance as investors digested various headlines. The Mag-7 outperformed with a 0.92% gain, but the overall market sentiment turned negative as investors reassessed risk and growth expectations in light of the new geopolitical tensions [1].
CONCLUSION
The escalation of US-Iran tensions triggered a broad-based pullback in global equities, reversing recent record highs across major indices. Rising Treasury yields and sharp declines in Asian markets underscore heightened investor caution and reassessment of risk. Market sentiment has shifted negative as geopolitical risks take center stage.
