Crude Oil Futures Face Two-Way Shock as Ukraine Strikes Russian Oil Depots and Diesel Sanctions Are Lifted
nashnova research
Ukraine launched its largest drone strike in over four years on a major St. Petersburg oil terminal, while Trump moved to waive Russia diesel sanctions on the same day — supply-disruption fear on one side, supply-relief expectations on the other — leaving Brent crude caught between opposing forces.
What did Ukraine hit, and how big was the strike?
Ukrainian drones struck a major oil terminal in St. Petersburg — the largest such attack since Russia's full-scale invasion began over four years ago.
Targets also included facilities in Putin's hometown and the Ryazan refinery.
This means → Russia's western refining and export infrastructure now faces a systematic threat, no longer sporadic harassment.
What exactly did Trump's "energy ceasefire" give away?
Trump declared an "energy ceasefire" for both sides and waived the Russia sanctions clause in the Lindsey Graham sanctions act he had signed earlier.
In return, Putin pledged phased diesel supplies to world markets: over 300,000 tonnes immediately, 500,000 tonnes in November, and another 1 million tonnes after that.
Zelensky called the waiver a move that "strengthens Putin's war against us" and dismissed the diesel deal as unlikely to lower U.S. fuel prices — the real driver of high prices is the Iran war and the Strait of Hormuz blockade, not a Russian supply shortage.
Where does Brent stand now?
December Brent settled Friday at $109.86 a barrel, briefly topping $110 — the first time since May 20 — marking a second straight weekly gain.
Drivers stacked up: Houthi attacks on Saudi Arabia, Iranian disruption deep inside the Strait of Hormuz, and Ukraine's strikes on Russian refining assets.
Goldman Sachs Research raised its December Brent forecast from $85 to $90, projecting a 2027 average of $80, citing Persian Gulf exports "recovering to near 2025 levels since late September."
What direction are hedge funds betting?
Goldman's trading desk reports that hedge funds are betting the opposite direction from Goldman Research — heavily long.
In the week of October 6–13, speculative money net-bought $4.9 billion in Brent futures; managed funds alone accounted for $3.4 billion.
32% of new longs were built through call options, adding roughly $700 million in fresh call exposure. In plain terms = funds aren't buying futures outright to bet on a rally — they're paying a smaller premium to "rent" the upside. If oil surges, they win big; if not, losses stay capped.
What is "gamma exposure," and why could it amplify oil-price swings?
Heavy call buying has reshaped the volatility surface — the options market's pricing map of future price distributions: Brent call implied volatility has risen relative to puts, signaling bigger bets on extreme upside moves.
Goldman's trading desk flagged that market makers' short gamma exposure — gamma exposure is the passive position that forces dealers who sold options to buy or sell futures in the same direction as price moves — has increased at the margin.
This means → if oil jumps on a geopolitical trigger, dealers must buy futures to hedge, pushing prices even higher — a self-reinforcing upward spiral. Put simply = dealers sold insurance; when oil rises they have to chase it, and chasing makes it more expensive.
Is there still room for longs to chase the rally?
Brent is near this year's spring war-premium highs, yet speculative net longs sit at roughly $14 billion — well below the April peak of about $38 billion.
Managed-fund net longs are around $25 billion, also below the April peak of roughly $46 billion.
This means → on paper, there is room for more money to pile in, but incremental capital increasingly prefers options over futures to participate. Whether the supply relief from sanctions waivers and the geopolitical premium from Ukraine's strikes reach an equilibrium is the core variable for this leg of the oil-price move.
