Global shares experienced a decline as investors awaited a crucial vote in Washington on the U.S. debt ceiling. The MSCI All-World Index, which was on track for its first monthly decline since February, dropped 0.4 in early U.S. hours. U.S. stock index futures also fell by 0.4. Concerns over faltering growth in China, the world's second-largest economy, added to the negative sentiment. China's manufacturing declined in May, coupled with a slowdown in services growth, indicating a loss of momentum in the Chinese economy and negatively impacting the global economic outlook. The Chinese yuan reached its lowest level since November, and other China-sensitive assets, such as the Australian dollar, crude oil, and copper, also experienced declines.
