The United Arab Emirates’ decision to quit Opec and Opec+ next month marks one of the most significant shifts in the global energy landscape in decades, even if its immediate effect on oil markets may prove muted. The move, announced as the FTSE 100 ended a six-day losing streak by edging 0.1% higher, came against a backdrop of heightened Middle East tensions, stalled US-Iran negotiations, and a tech sell-off triggered by reports that OpenAI had missed internal targets for users and revenue.
London’s benchmark index closed up 11.70 points at 10,332.79, while the FTSE 250 fell 0.8% to 22,399.42 and the AIM All-Share dropped 1.0% to 786.90. In Europe, the CAC 40 in Paris lost 0.5% and Frankfurt’s DAX 40 slid 0.3%, extending its losing streak to seven consecutive sessions. Wall Street was mixed: the Dow Jones Industrial Average rose 0.2%, but the S&P 500 fell 0.8% and the Nasdaq Composite dropped 1.4%, led lower by technology stocks.
Oil prices continued to climb. Brent crude traded at $111.77 a barrel on Tuesday afternoon, up from $108.92 at Monday’s London equities close, while WTI crude approached $100 a barrel. Qatar has warned of the possibility of a “frozen conflict” in the Gulf as talks between the United States and Iran remain deadlocked. The Strait of Hormuz, a vital chokepoint for global oil shipments, is largely impassable, and President Trump has reportedly rejected Iran’s latest proposal to resolve the conflict.
UAE’s Opec Exit: Implications for Global Energy
The UAE’s departure from Opec and Opec+, effective 1 May 2026, ends nearly 60 years of membership. The government described it as a “sovereign national decision” that would allow the country to pursue its own strategic objectives and meet growing long-term global energy demand after recent investments to boost production capacity. Michael Brown, an analyst at Pepperstone, said the main surprise was “its timing, as opposed to its substance”. He noted the UAE’s dissatisfaction with Opec has been “clear for some time, with the country of the belief that Opec quotas are an unfair limit, constraining the nation’s major infrastructure investment projects”.
While the move is undoubtedly pivotal for the global energy market, Brown argued that near-term implications are likely to be “relatively limited”. “Though the UAE have pledged to ‘gradually’ increase production after their departure, it goes without saying that actually doing so at present is somewhere between difficult, and impossible,” he said. “As the US-Iran conflict continues, and the Strait of Hormuz remains impassable, the most significant issue for the crude market is not production, but actually shipping product to where it is needed. Today’s announcement does not change anything on that front.”
Saul Kavonic, head of energy research at MST Financial, told the BBC the decision marked “the beginning of the end of Opec”. “With the UAE leaving, Opec loses about 15% of its capacity and one of its most compliant members,” he said. The departure could weaken Opec’s cohesion, although analysts cautioned that any immediate impact on global supply is constrained by the inability to ship crude through the Strait of Hormuz.
OpenAI Misses Targets as Tech Stocks Sink
Across the Atlantic, technology stocks bore the brunt of Tuesday’s losses after a Wall Street Journal report revealed that OpenAI had missed internal targets for users and revenue. The company aimed for one billion weekly active users for ChatGPT by the end of 2025 but failed to reach that goal, and also fell short of multiple monthly revenue targets this year. According to the report, OpenAI chief financial officer Sarah Friar has privately warned company leaders that the firm might be unable to meet future computing contract obligations if revenue growth does not accelerate.
The report sparked a sell-off in shares of companies with exposure to the artificial intelligence boom. Oracle dropped 3.6%, Advanced Micro Devices fell 3.5%, and Nvidia declined 2.1%. SoftBank Group, which holds a 13% stake in OpenAI, plunged 9.9%. CoreWeave fell 3.5% and Broadcom declined 5.21%. Investor fears centred on whether massive spending on AI infrastructure can be sustained, particularly given Oracle’s $300 billion, five-year cloud deal with OpenAI: the company’s debt-to-equity ratio stands at 3.66 and total debt rose 60% to $153.1 billion last quarter.
Wedbush Securities pushed back against the Wall Street Journal report. “Overall, we believe OpenAI has been tracking very high demand on both the consumer and enterprise front and we strongly disagree with the notion that growth is weakening. We would be buyers of AI-driven tech stocks this morning and in particular Oracle on this way overreaction to this WSJ report in our view,” the broker said. OpenAI spokesperson Steve Sharpe dismissed the report as “clickbait”, asserting that the company’s business is “firing on all cylinders”.
The yield on the US 10-year Treasury rose to 4.36% on Tuesday from 4.32% on Monday, hitting a one-month high, while the 30-year yield stretched to 4.96% from 4.93%, both moves attributed to Middle East uncertainty and rising oil prices.
Company-Specific Results
On the FTSE 100, BP rose 1.1% after reporting better-than-expected first-quarter results. Underlying replacement cost profit ballooned to $3.20 billion in the first quarter of 2026 from $1.38 billion a year earlier, well ahead of the company-compiled consensus of $2.67 billion. The strong performance was driven by exceptional oil trading, higher refining margins and steady upstream production. It was BP’s highest quarterly profit since 2023, beating expectations by 20% thanks to the Iran war boosting its trading results. However, net debt increased to $25.3 billion, and the company noted that upstream production, refining margins and fuel volumes remain sensitive to Middle East disruptions. BP maintained its quarterly dividend at 8.320 cents per share and reiterated 2026 capital expenditure plans. It has agreed to divestments including the Gelsenkirchen refinery and a $6 billion Castrol transaction, and suspended its share buyback programme in February to prioritise debt reduction.
Barclays eased 0.2% as in-line results failed to energise its share price. The London-based lender reported pre-tax profit of £2.81 billion for the first quarter, up 3.3% from £2.72 billion a year earlier but just shy of the company-compiled consensus of £2.83 billion. Jefferies analyst Jonathan Pierce described the results as “solid enough” with “no fireworks”.
A weaker gold price hit mining stocks. Fresnillo fell 2.0% and Endeavour Mining lost 4.5% as the yellow metal traded at $4,579.32 an ounce on Tuesday, down from $4,677.74 on Monday — its lowest level since late March. The decline was attributed to surging oil prices, stalled US-Iran negotiations and rising Treasury yields.
On the FTSE 250, Telecom Plus tumbled 17% after guiding to low-end full-year profit, while SSP fell 5.5% after UBS downgraded its rating to “neutral” from “buy”, citing increasing risks to volumes in the travel retail industry linked to the Middle East conflict. Building materials firm Travis Perkins slid 4.0% and housebuilder Taylor Wimpey fell 5.3% as investors weighed trading updates. Taylor Wimpey reported a dip in UK net private sales, with a sales rate of 0.74 per outlet per week, down from 0.77 a year earlier; cancellation rates improved to 14% from 16%. Its order book value decreased by 4.5% to £2.23 billion, and build cost inflation is now expected to be in the low to mid-single digits for 2026 due to rising energy costs.
In currency markets, the pound eased to $1.3505 from $1.3549 on Monday. Sterling edged lower against the euro to €1.1534 from €1.1543. The euro fell to $1.1709 from $1.1733, while the dollar strengthened to ¥159.61 from ¥159.27 against the yen.
