Global Markets Weekly Update Summary
Week Ending September 2026
U.S. Market Overview
Major U.S. stock indexes ended the week lower due to escalating Middle East conflicts, which drove oil prices up and raised inflation concerns. The Russell 2000 and S&P MidCap 400 saw the largest declines, while the Nasdaq Composite fared better.
Middle East Tensions
Geopolitical tensions, particularly attacks on Saudi energy infrastructure, led to a spike in oil prices, with Brent crude nearing USD 110 per barrel. This situation contributed to rising U.S. Treasury yields, with the 10-year note reaching approximately 4.97%.
Inflation Data
Producer prices rose 0.4% in August, with a year-over-year increase of 5.4%. The consumer price index (CPI) showed a year-over-year inflation rate of 3.4%, leading to an increased market-implied probability of a September rate hike to about 87%.
Consumer Sentiment
The University of Michigan's consumer sentiment index fell to 47.8, reflecting concerns over rising fuel prices and trade tensions.
European Market Overview
The STOXX Europe 600 Index declined 1.66% as inflation concerns rose due to geopolitical tensions. The ECB raised interest rates by 25 basis points, citing persistent inflation risks.
Japan Market Overview
Japan's stock markets fell, with the Nikkei 225 down 1.55%. Expectations for a near-term Bank of Japan rate hike contributed to market pressures, despite some strength in AI and semiconductor stocks.
China Market Overview
Chinese equities declined, with the Hang Seng Index dropping 3.30%. The government announced plans to recapitalize state financial institutions, while exports showed strong growth despite uneven domestic demand.
Other Key Markets
In Saudi Arabia, stocks ended slightly lower amid oil disruptions and geopolitical risks. Brazil's markets faced volatility due to rising oil prices but received support from softer-than-expected inflation data.
