KEY POINTS
- Brent crude surged 4.3% to $95.42 per barrel on Sunday as Iran declared the Strait of Hormuz closed to commercial shipping for the second time in seven weeks.
- The move follows the U.S. Navy's seizure of an Iranian vessel and retaliatory fire from Iran's Revolutionary Guard on a commercial tanker, reigniting the supply-disruption premium.
- If the ceasefire collapses Wednesday, Goldman Sachs estimates Brent could breach $110 within a week, repricing inflation expectations and forcing the Fed to recalibrate.
Brent crude is knocking on the door of $100 per barrel again, and the only thing standing between here and triple digits is a ceasefire that expires in three days.
June Brent futures settled at $95.42 on Sunday, up 4.3% on the session, after Iran declared the Strait of Hormuz closed to commercial vessels for the second time since the conflict began in March. WTI crude for May delivery rose 5.6% to $88.54, erasing the entirety of last week's 10% plunge that had briefly pushed the contract below $84.
The reversal was stunning in its speed. Just 48 hours ago, oil traders were pricing in cautious optimism that the two-week ceasefire would hold and potentially extend. That thesis died Saturday when Iranian Revolutionary Guard forces fired on a commercial tanker in the strait and a U.S. Marine detachment boarded and seized an Iran-flagged container ship attempting to breach the American blockade.
The Supply Math Is Brutal
The Strait of Hormuz is not a marginal chokepoint — it is the chokepoint. Roughly 20 million barrels per day transit through its two narrow shipping lanes, accounting for approximately 20% of all seaborne crude oil trade globally. When Iran first closed the strait on March 4, Brent rocketed past $120 within days. The IEA characterized that disruption as the largest in the history of the global oil market.
The ceasefire partially reopened the shipping lanes in early April, allowing some tanker traffic through under escort. That brought prices down from their March highs but never fully normalized flows. Saudi Arabia and the UAE rerouted some exports via the Red Sea pipeline infrastructure, but that capacity handles only a fraction of normal strait volumes.
Now, with the strait effectively shut again, the market faces the same supply deficit that caused the March spike — but with less strategic petroleum reserve capacity available. The U.S. released 30 million barrels from the SPR in March, and the IEA coordinated a separate 60-million-barrel release. Those buffers are thinner now.
The Inflation Feedback Loop
Oil at $95 is not just an energy story. It is a macro story that touches every corner of the market. The EIA reported that energy prices rose 12.5% year-over-year in March, and headline CPI reaccelerated to 3.3%. Core CPI held at 2.6%, but the Fed knows that sustained oil above $90 feeds through to transportation, food, and manufacturing costs within 60 to 90 days.
New York Fed President John Williams said last week that the Iran conflict "has already shown signs of hiking prices and slowing growth" — a stagflationary combination that leaves the central bank with no good options. The Fed meets April 28-29 with rates at 3.50%-3.75%, and futures markets price a near-certainty of a hold. But if oil stays above $95 through the summer, the inflation path makes even the September cut that markets have been banking on look doubtful.
Energy equities will be the obvious beneficiaries at Monday's open. The SPDR S&P Oil & Gas Exploration & Production ETF (XOP) has already outperformed the S&P 500 by 22 percentage points year-to-date. Refiners and midstream names have lagged the upstream rally, creating a potential catch-up trade for those who believe the supply disruption persists.
The $100 Line in the Sand
The psychological $100 level on Brent is now the market's focal point. Analysts warn oil could surge toward $100 if the crisis worsens, and Goldman Sachs estimates a full resumption of hostilities could send the contract past $110 within a week. The options market is already pricing elevated call skew above $100 for June and July contracts.
For traders, the setup is binary. If Wednesday's ceasefire holds and extends, oil likely retreats toward the low $80s and the inflation narrative softens. If it collapses, $100 Brent becomes a floor, not a ceiling, and the entire second-half growth story needs to be rewritten. Position sizing should reflect that asymmetry.
