NEW YORK, January 4, 2026, 08:39 ET — Market closed
- Phillips 66 closed Friday up 1.2% at $130.57, before weekend U.S. strikes on Venezuela
- Venezuela’s oil exports have stalled under a U.S. blockade and “oil embargo,” sources and Trump said
- Traders are watching oil futures and Washington’s next moves on sanctions and tanker traffic ahead of Monday’s open
Phillips 66 shares will be in focus when U.S. trading resumes Monday after the United States seized Venezuelan President Nicolás Maduro in a Saturday operation that threatens to reshape crude flows and refinery economics. The refiner’s stock last closed at $130.57, up about 1.2%. MarketWatch
The weekend escalation matters now because it landed when markets were shut, forcing investors to reprice energy names at the next open with limited price discovery in between. For refiners such as Phillips 66, the key swing factor is whether Washington’s policy leads to a near-term squeeze on heavy crude supplies — or, over time, a rerouting of Venezuelan barrels that improves feedstock access for U.S. plants.

Venezuela’s crude shipments were already struggling under a U.S.-announced blockade of sanctioned tankers, and are now “paralyzed” because port officials have not authorized loaded vessels to depart, four sources close to operations said. Separately, two sources with knowledge of PDVSA operations said production and refining were operating normally and suffered no damage from the strike. Reuters
Phillips 66 ended Friday about 10% below its 52-week high of $144.96 set on Dec. 11, MarketWatch data showed — a level some traders will watch if energy shares catch a bid on fresh geopolitics. U.S. refining peers Valero and Marathon Petroleum also closed higher on Friday. MarketWatch
Trump said on Saturday an “oil embargo” on Venezuela was “in full effect,” after U.S. forces extracted Maduro and announced it would oversee a political transition. Trump has also said the United States would “run” the country for a period, without detailing how that would work. Reuters
In December, Trump announced a blockade of oil tankers entering or leaving Venezuela and the United States seized two cargoes of Venezuelan oil, according to Reuters. Those measures cut the OPEC country’s exports last month to about half of the 950,000 barrels per day it shipped in November, Reuters cited monitoring data and internal documents as showing. Reuters
A separate Reuters analysis said the bigger, medium-term market story is a potential rerouting of Venezuelan heavy crude back toward the United States and away from China, where independent refiners have bought discounted barrels under sanctions. China accounted for more than half of Venezuela’s crude exports of 768,000 bpd last year, according to data from analytics firm Kpler cited by Reuters. Reuters
That shift would matter for U.S. Gulf Coast plants, many of which were built to process heavy-grade crude — thicker, more sulfur-rich oil like Venezuela’s — into fuels such as gasoline and diesel. Reuters estimated U.S. purchases could rise by more than 200,000 bpd within months if Venezuelan flows to Chinese “teapot” refiners are redirected. Reuters
For Phillips 66, investors will be tracking how the shock hits refining “crack spreads” — the margin between crude costs and refined product prices — and whether product prices keep up if crude swings. Oil had been fairly stable around $60-$61 a barrel in recent weeks, Reuters reported, but traders expect volatility at the reopen. Reuters
“Right now, oil markets are being driven less by supply–demand fundamentals and more by political uncertainty,” said Jorge Leon, head of geopolitical analysis at Rystad Energy and a former OPEC official. OPEC+ kept oil output policy unchanged on Sunday and said the group will next meet on Feb. 1. Reuters
But the trade is not one-way for refiners. If the embargo bites and heavy crude tightens before any rerouting materializes, feedstock costs can rise faster than gasoline and diesel prices, squeezing margins; a broader risk-off move in equities would add another layer of volatility. Reuters has also reported that meaningful increases in Venezuelan output are unlikely for years even if U.S. companies return. Reuters
The next company-specific catalyst is Phillips 66’s fourth-quarter and full-year results, due Feb. 4, when management is scheduled to discuss the numbers on a webcast after releasing results earlier that day, the company said. Phillips66
Markets will watch the first indications from oil futures trading Sunday evening, then Phillips 66’s reaction at Monday’s cash open. Investors will also be watching for fresh U.S. guidance on sanctions, any restart in Venezuelan tanker authorizations, and the next OPEC+ meeting on Feb. 1 ahead of Phillips 66’s earnings on Feb. 4.
