Finance Brief: Oil plunges as Iran talks move, and AI deals keep coming
Oil fell hard on Monday as hopes grew that talks could cool the confrontation with Iran. For households and governments across the Turkic world, that shift matters because cheaper oil cuts fuel bills in Türkiye while trimming export earnings in Azerbaijan and Kazakhstan.
Brent crude fell about 6 percent on Monday to 106.65 dollars a barrel, and United States crude fell 6.1 percent to 97.75 dollars, according to Reuters figures reported by CNA. The fall came after Brent ended October at a six-month high, and it followed the announcement that Iran's supreme leader had authorised his government to negotiate with Washington. This run's threshold watch had already flagged Brent breaking below 106 dollars intraday, so Monday's move is a continuation, not a surprise.
The watch items now split two ways. Analysts cited in the coverage warn rhetoric could harden again after the United States midterm elections and push Brent back toward 120 dollars, while Goldman Sachs raised its forecasts on the supply risk and said Brent could reach 140 dollars in 2027 if Gulf output stays 3.5 million barrels a day below its 2025 average. In plain terms: the market has priced in a deal, and any failed talk or new Hormuz incident reprices it fast.
The AI money story of the day is just as large. $MRVL, the chip designer Marvell, agreed to buy optical-parts maker Lumentum in an all-stock deal worth about 115 billion dollars including debt, Reuters reported. Lumentum holders get 4.5 Marvell shares per share, about 1,132 dollars a share, a 23.9 percent premium to the October 28 close, and about a third of the combined company. The deal is expected to close in the first half of 2028, subject to shareholder and regulatory approval, and the companies put their combined addressable market at 550 billion dollars.
Why it matters beyond the ticker: the AI build-out is moving from the chips themselves to the optical links between them, and Marvell is buying the lasers and transceivers that carry data inside data centres. Nvidia, which invested 2 billion dollars in each company earlier this year, sits on both sides of the deal. The risk to the read is approval: regulators and shareholders can still slow or reshape a deal this size.
Closer to home, Kazakhstan and China are working on a 200 million dollar fund for Middle Corridor infrastructure, and Uzbekistan's remittances reached 15.16 billion dollars in nine months, up 8.9 percent, though growth slowed in the third quarter. Small businesses now produce 53.8 percent of Uzbekistan's GDP, a reminder that the region's growth engine is increasingly domestic and small-scale, not just pipelines and state projects.
Levels to watch: Brent around 105 to 106 dollars, where buyers stepped in on Monday, and 120 dollars if diplomacy stalls. What would invalidate the calmer-oil read is simple: talks collapse, or another mine or strike in Hormuz waters.
