Brent crude fell sharply on Sunday, dropping more than 7% to around $89.73 per barrel after Iran said it would suspend attacks as long as a US pause in hostilities remained in place, pulling the international benchmark back below $90 for the first time in days and partially unwinding Thursday's surge above $100 triggered by Houthi strikes on Saudi tankers in the Bab el-Mandeb Strait.
International benchmark Brent crude futures for September delivery fell 7.3% to around $89.73 a barrel while US West Texas Intermediate crude for September delivery similarly dropped 6.5% to $83.47 a barrel, as the prospect of shipping flows normalising through the world's most critical oil chokepoints drove one of the sharpest single-day price reversals of the year.
The move recaps a pattern that has defined global oil markets since the conflict between the United States and Iran erupted in late February: a provocation sends Brent surging, a diplomatic signal sends it tumbling, and neither direction holds for long. Within the space of five trading days this week, Brent climbed from the mid-$70s to above $100 on Houthi strikes, then shed more than 10% on Iran's ceasefire offer, leaving traders caught in a whiplash market where every geopolitical headline carries a price tag and no position is safe overnight.
The immediate catalyst for Sunday's reversal was Iran's conditional offer to stand down, but the broader context matters. Separately, at least five supertankers carrying a combined 10 million barrels of Saudi oil loaded from Ras Tanura have exited the Strait of Hormuz, with Saudi Aramco switching to spot pricing to speed up Asian sales, a move that signals Riyadh's determination to restore normal export volumes as quickly as geopolitics allow.
UBS cut its Brent forecasts in response to the improved shipping picture, reducing its third-quarter estimate by $25 per barrel to $80, lowering its Q4 2026 forecast by $10 per barrel to $80, and trimming its 2027 outlook by $10 per barrel to $75. HSBC similarly expected the market to absorb returning Middle East barrels through gradual restocking alongside the end of International Energy Agency strategic stock releases in July.
For Nigeria, the week encapsulates the impossible arithmetic of being a major oil producer in the middle of a geopolitical conflict it has no power to influence. Thursday's $100 handle briefly put every barrel Nigeria pumped at its 74-month production high well above the ₦64.85 per barrel budget benchmark, generating paper windfalls the Federation Account had not planned for.
Sunday's reversal toward $89 compresses that windfall in real time, and the conditional nature of Iran's ceasefire offer means the market could be back above $95 before the week is out. Dangote Refinery, which raised its ex-depot petrol price to ₦1,215 per litre last week as crude costs rose, now faces the same crude price volatility in reverse, with the political pressure to cut prices again likely to follow quickly if Brent holds its Sunday decline into the trading week. The strait has not reopened. The ceasefire has not been formalised. And the gap between where Brent closed on Thursday and where it closed on Sunday tells you everything about how fragile the current equilibrium actually is.
