Crude prices rose sharply, with Brent nearing $111 per barrel and US West Texas Intermediate crossing the $100 mark for the first time in weeks. The price rally reflects constrained energy flows and investor anxiety as tensions persist between United States and Iran, with no clear diplomatic breakthrough in sight.

Further rattling markets, the United Arab Emirates announced its decision to exit OPEC and the broader OPEC+ alliance. The move is seen as a significant shift, potentially weakening the group’s influence over global oil supply, especially given the UAE’s position as one of its top producers.

Analysts say the departure underscores internal strains within producer alliances during periods of geopolitical stress. While the immediate market reaction was limited, the longer-term implications could reshape supply coordination and price stability.

On Wall Street, major indices including the S&P 500 and Nasdaq Composite declined as investors reassessed the sustainability of the AI-driven rally. Reports suggesting OpenAI missed internal growth targets added to concerns over heavy capital expenditure in the sector.

Technology and semiconductor stocks — including Oracle, AMD, and Broadcom — saw notable declines, reflecting broader caution among investors ahead of key earnings announcements from major firms.

Meanwhile, rising oil prices pushed US Treasury yields higher, as markets priced in inflationary pressure. The policy outlook remains in focus, with decisions expected from central banks including the Federal Reserve, European Central Bank, and Bank of England.

The Bank of Japan has already held interest rates steady, though divisions among policymakers signal potential shifts ahead.

Currency markets also reflected uncertainty, with the US dollar holding firm as a safe-haven asset, while the Japanese yen fluctuated near intervention-sensitive levels.

Overall, markets remain highly reactive to geopolitical developments, particularly the unresolved Iran conflict and disruptions in global energy supply chains, both of which continue to drive inflation fears and investor caution.
