Crude oil had one of its wildest days of the autumn on Monday. The weekend delivered fresh drone and missile attacks across the Gulf. Houthi forces claimed a Saturday drone strike against Riyadh's main airport; the reported toll was 13 dead and more than 300 injured, and Saudi authorities logged a second airport attack on Sunday. British maritime monitors added two vessel incidents: one tanker hit by a drone close to Oman's Sohar anchorage, a second ship struck by an unidentified object inside the Strait of Hormuz.
Relief came first. Brent slid $1.42 to $103.35 and WTI gave up the same $1.42 to land at $90.42 as traders priced in Trump's Sunday announcement — Russia and Ukraine had settled on a halt to strikes against each other's energy sites, on top of Friday's US-Russia diesel arrangement. Then Zelensky said on Monday he was still waiting for the details and that Russian attacks on Ukrainian energy had gone on, with Moscow not even commenting. Prices snapped back: Brent up 1.2% to $106.19 by 11:24 GMT, then $106.73, up 1.9%, by New York mid-morning. WTI followed to $93.73, up 2.1%.
Goldman Sachs reset its view on Sunday: December 2026 Brent is now $90 a barrel, up from $85 — a 6% lift the bank ties to supply-side downside risks slowing the fade of the time-spreads risk premium, estimated above $20 a barrel. The 2027 average call stays at $80, with a $125 worst case. WTI should average $81 in December and $73 in 2027, with high US-to-Europe shipping costs keeping its discount to Brent wide.
| Goldman call | Figure |

| Brent Dec 2026 | $90 |
| Brent 2027 average | $80 |
| Brent 2027 worst case | $125 |

| WTI 2027 | $73 |
| War risk premium | Above $20/bbl |
Why it matters
Take Goldman's $20 of risk premium out of Monday's $106-107 prints and Brent's implied fundamental is about $86-87 — right where the bank's December target sits. Spot is a war quote; the only question is whether the premium fades or explodes. The physical backdrop defends it: Gulf crude and condensate exports have only climbed back to 91% of prewar levels, refined-product exports lag at 60%, and the weekend's tanker hits threaten the September recovery in Hormuz shipments. OPEC's secretary general added a demand counterweight — the group now sees 2026 demand up just 400,000 barrels a day, versus 1.4 million at the year's start.
What to watch
- Whether Washington or the Saudi-led coalition answers the weekend strikes — Trump floated on Saturday the US joining Saudi operations against the Houthis.
- Any official Russian response on the energy truce; Zelensky says strikes continued Monday.
- Insurance and routing fallout from the Sohar and Hormuz vessel incidents.
The two forecasts that matter:
- Goldman Sachs now sees Brent at $90 in December (from $85), an $80 average in 2027, and a $125 worst case.
- OPEC expects 2026 demand growth of only 400,000 bpd, down from its 1.4 million forecast when the year began.
MarketRadar take
Monday's tape shows how fast a ceasefire announcement trades against fresh attacks — the relief rally died within hours.
Near-term, the balance favors higher prices: two vessel incidents in one weekend, and a $20 war premium that could fatten quickly if tankers reroute around the strait. Medium-term, Goldman's arithmetic is hard to ignore — spot minus the premium lands near $86, the bank's December call is $90. But that base case only survives if the September export recovery holds. If Hormuz shipments break again, the $90 and $80 targets mean nothing.
