The ceasefire broke and crude ripped. Then it gave half of it back.

One shock ran the whole week. The US and Iran ceasefire collapsed, US strikes landed on Wednesday July 8, crude spiked hard, and by Friday the market had handed back about half the move. Underneath the fireworks, the real story is a glut that never went away, and a shortage that is sitting in the products, not the barrel.

The week opened with $CL at a five-month low near 68.55, right after Saudi Arabia cut its Arab Light official selling prices by the most in at least 26 years. That is a supply-glut signal, full stop. Then Wednesday hit, the risk premium came screaming back for 48 hours, and Thursday and Friday were spent deciding how much of it to keep.

$CL and $CO

Friday closes and weekly moves:

• $CL (WTI front month): 71.41, up 4.2% on the week (+2.86)
• $CO (Brent front month): 76.01, up 5.6% (+4.02)
• $CL2 (WTI second month): 71.34, up 4.1%

From Monday’s open to Wednesday’s intraday high, $CL ran roughly 7%, and $CO briefly printed around 80. Both then gave back about half the spike into the close. The week ends green, but well off the highs, which tells you the market is not convinced the disruption is permanent.

The $CL discount to $CO widened

The spread by day, in dollars per barrel: minus 3.44 Monday, minus 3.72 Tuesday, minus 4.50 Wednesday, minus 4.22 Thursday, minus 4.60 Friday.

The discount blew out to minus 4.60 by Friday, the widest of the week, after touching minus 4.57 Wednesday morning. Two forces are pulling against each other. $CO carries the geopolitical premium, since it is the barrel exposed to Hormuz and Iran. $CL is stuck with the domestic problem: surging US production and those Saudi price cuts. The Houston physical premium to futures rose to plus 40 cents on Wednesday, the highest since mid-June, as strong refining margins pulled barrels into the pipeline market. The spread tells you where the risk is and where the glut is, at the same time.

Prompt spreads: the tell of the week

This is the part to watch. The $CL prompt spread (M1 over M2) had already flipped into contango on July 2 for the first time since November 2024, a market pricing near-term oversupply out loud. Wednesday’s shock forced both $CL and $CO timespreads back into backwardation, the firmest since late June, as traders repriced the risk of a real supply hit. By day, $CL M1-M2 ran minus 0.01, plus 0.10, plus 0.25, plus 0.18, plus 0.07, while $CO went minus 0.25, plus 0.04, plus 0.45, plus 0.10, minus 0.02.

Then it faded. By Friday both were back toward flat, $CO M1-M2 closing at minus 0.02. The structure spiked on fear and settled back on fundamentals inside three sessions. The failure to hold backwardation is the bearish structural signal of the week: the curve is telling you the spike was a positioning event, not a fundamental supply loss.

Crack spreads: the real shortage is not in crude

If you only watched crude this week, you missed the actual story. It was in the products.

• 3-2-1 crack: 61.72 Monday (all-time record), 64.58 Wednesday peak, 61.91 Friday
• $XB (RBOB gasoline) crack: 53.94 Friday, the strongest since 2022
• $HO (heating oil and diesel) crack: exploded to 80.10 Wednesday, 77.83 Friday
• Gasoil over $CO crack: record 58.80 Thursday, eased to 54.97 Friday

The 3-2-1 printed an all-time record on Monday, with refining margins stretched and RINs also at record levels in Bloomberg data. Then the diesel side went vertical, the $HO crack blowing out to 80.10 Wednesday as Russia banned diesel exports and US distillate stocks drew down, right on top of the Iran shock.

Here is the divergence that matters. Crude has handed back nearly all of its wartime gains, but product margins are still at or near historic highs. Bloomberg Intelligence called it increasingly concerning, and they are right to. The benchmark barrel can normalize all it wants. The shortage in gasoline, diesel and jet fuel is a different problem, and it is not resolving.

Volatility and positioning: a hedge, not a chase

The options tape said a lot. $CO options volume hit the second-highest on record on Wednesday, and puts outran calls even as futures were spiking. That is a market hedging the move, not piling into it. Implied vol on both $CO and $CL jumped, with $OVX spiking, and call skews turned the most bullish in almost a month.

The setup made the move violent. Money-manager net length in $CO had fallen to the lowest since December, and $CO had been oversold on its 14-day RSI for ten sessions straight into Monday. Open interest was thin on both sides, $CO at the lowest since March 2025 and $CL the lowest since December. Light positioning plus an extreme short base is exactly the fuel for a short-covering squeeze, and Wednesday delivered it.

There was a mechanical leg too. September $CO traded through 80 on Wednesday, right where more than 50,000 lots of calls and puts were parked, another 50 million barrels of exposure, with a further 75,000 lots up at 85. Dealer gamma around those strikes almost certainly added to the push before the reversal took it back. And Deutsche Bank flagged the standout dislocation to watch: $CO around 73 to 76 while the 10-year Treasury yield holds near 4.5%, a relationship that has decoupled from the tight correlation seen during the earlier Iran escalation.

Oil ETFs (weekly total return)

• $USO (WTI front-month futures): up 4.2%
• $XLE (energy sector equities): up 3.7%
• $XOP (oil and gas E&P): up 3.0%

$USO’s 4.2% lines up almost exactly with $CL’s weekly gain, which confirms there was basically no roll drag with the prompt spread sitting flat. The more interesting bit is that the equities lagged the barrel. $XLE and $XOP both trailed $USO, and that gap is the market telling you it does not trust the spike. Energy stocks are pricing the medium-term supply picture, not the 48-hour war premium, and that picture is heavy: JPMorgan is talking about a wave of oil about to hit the market, and Citi still sees $CO drifting to 60 by year-end.

Where it leaves us

Strip out the fireworks and this was a bearish crude week wearing a bullish costume for two days.

The curve is the tell. Prompt spreads jumped into backwardation on the shock and could not hold it, sliding back toward contango by Friday. That is a market saying the geopolitical spike was a positioning event, not a real supply loss. $CO net-longs are at multi-month lows, open interest is collapsing, and Saudi Arabia just cut prices by the most in 26 years. None of that is a floor being built.

The real action was in products. Crack spreads sat at or near all-time records all week, and the crude versus products divergence is the structural story to carry forward. Refiners are the clear winners. A Russian diesel export ban and Hormuz-related distillate tightness are keeping the diesel and gasoil cracks historically rich even while crude backs off.

On vol, the Wednesday spike was real but the positioning underneath says hedge, not chase. Puts outran calls into the move, and the squeeze was violent mainly because the market went in thin and heavily short. Keep one eye on the $CL over $CO spread at minus 4.60. It is the cleanest real-time read on how much Hormuz risk the market is actually willing to pay for, and right now it is fading.
