On May 26, 2026, the U.S. stock market was closed all day in observance of Memorial Day, triggering a short-term rhythm adjustment in global financial markets. All US-related derivative trading arrangements were adjusted accordingly. Brent crude oil trading on the Intercontinental Exchange, precious metals and US stock index futures trading on the CME Group all ended early, resulting in reduced trading liquidity in the global financial market. As the core pricing center of global capital markets, the closure of US stocks has weakened global market trading activity. Without the driving force of US capital trading, trading sentiment in Asia-Pacific and European markets turned cautious, with overall market volatility narrowing significantly. Most institutional investors chose to wait and see, suspending large-scale position adjustments and trend trading operations. In the commodity market, although trading continued, the lack of US market participation led to weakened price volatility. International crude oil and precious metal prices maintained a volatile consolidation trend after the sharp correction driven by US-Iran negotiation news, with no new directional breakthroughs. Market analysts pointed out that the short-term closure of US stocks will not change the existing market trend logic. The core market driving factors still focus on global energy supply changes, US inflation trends and Federal Reserve policy expectations. After the US stock market resumes trading, global capital will restart active allocation, and market volatility and trading volume will return to normal levels. Investors will continue to focus on the follow-up progress of the US-Iran agreement and global macroeconomic data to grasp the next stage of market trend opportunities.
