Two risk premia deflated in six days: GL 134C reinstated Russian in-transit cover on 18 May, then the 23 May Iran MOU knocked Brent $14 lower. The flat price and the light-sweet spreads are unwinding the geopolitical bid. The gasoil crack is not, because the shortage is physical. Fade the premia, hold the crack, watch the offside WTI length get carried out.

Bradley T. Smith signed General License 134C at 14:05 EDT on Monday 18 May, reinstating Western vessel services on Russian crude loaded by 17 April and reversing the cliff the market had priced two days earlier.
On 18 May, the US Treasury issued a new permit, General License 134C, reinstating shipping services for Russian oil cargoes loaded before 17 April. It runs until 17 June.
The permit narrows each time it renews, as the loading cutoff date stays fixed. Cuba is carved out entirely, so any cargo that touched Cuban logistics loses its protection.
Brent fell from $110.34 on Wednesday 20 May to $96.14 on Sunday 24 May after Trump called the Iran deal 'largely negotiated', deflating the Hormuz war premium that the light-sweet complex had carried.
United StatesBrent Crude fell from $110 to $96 across 20-24 May after Trump announced a preliminary deal with Iran that could reopen the strait of Hormuz. The drop of $14 in four trading sessions was one of the sharpest weekly moves in recent years.
The deal is partial: Iran's nuclear stockpile was left out, and full talks are expected to take another 30-60 days. Diesel prices in Europe may ease slightly, but the underlying shortage of distillates has not changed.
CFTC Commitments of Traders for 19 May put NYMEX WTI non-commercial net long at +172,580 contracts, a 177,000-contract swing in three weeks that the Iran MOU then carried out four sessions later.
US futures data from 19 May showed traders had built a large bet on rising oil prices: about 172,580 contracts net long on US crude. That was a swing of roughly 177,000 contracts in three weeks.
The build-up happened before Trump's 23 May Iran announcement. When the news landed, the crowded long was caught wrong, and the forced unwind deepened the Brent slide.
Argus reported on 24 April that EU gasoil imports ran 695kbd, down 38% month-on-month and the lowest since its tracking began in 2016, with the ICE Gasoil crack near $54 as Brent fell.
United KingdomEuropean diesel imports collapsed 38% in April to 695,000 barrels a day. That was the lowest since records began in 2016, after the Hormuz closure cut Gulf supply. BP's Rotterdam refinery also shut both crude units.
With less diesel arriving and less made at home, the refining margin held near $54 a barrel even as crude prices fell.
TD3C peaked at WS458.75 on 11 May on the Hormuz surge; with the BDTI still reading 2,249 on 20 May, GL 134C's restored cover is pulling the compliance premium out of TD7 and TD19 first.
GL 134C's 18 May signing began easing the freight premium on Baltic Sea tanker routes carrying Russian crude. The penalty had covered shipowners for legal uncertainty.
The Baltic Dirty Tanker Index still read 2,249 on 20 May, far above normal, as Hormuz-driven costs lingered. No clean supertanker print was published this week, so the easing is confirmed only for Baltic routes.
OFAC added nine Cuban officials to the SDN list on 18 May, one based in Cienfuegos, while GL 134C paragraph (b)(1) excludes Cuba outright, creating a cargo class that loses its waiver on a single Cuban touch.
On 18 May, the US Office of Foreign Assets Control signed GL 134C and excluded Cuba from the permit. It also added nine Cuban officials to its blacklist. Any Russian oil cargo that passed through Cuban logistics loses its protection.
One sanctioned official sits in Cienfuegos, home to Cuba's main refinery. Traders must now trace each cargo's full voyage.
The EU's 20th package, adopted 23 April, left the full maritime-services ban out for lack of EU-27 unanimity, designating Karimun Oil Terminal in Indonesia but leaving the dark-fleet cost curve untouched.
The EU's 20th sanctions package, adopted in April, added 46 more Russian-linked ships to a ban list, lifting the total to 632. It stopped short of banning European insurers from covering those ships.
The insurance ban failed for want of unanimity among all 27 EU states. The next chance to force it is the G7 summit in Kananaskis, Canada, on 12-15 June.
EIA logged a 7.9mb US crude draw to 445.0mb in the week to 15 May, the window's largest, while Fujairah stocks rebuilt 96kbd to 6.593mb, a first build in ten weeks off a record low.
US crude stockpiles fell 7.9 million barrels in the week to 15 May. Refineries ran above 90% capacity. At the Emirati Port of Fujairah, oil storage rebuilt slightly for the first time in ten weeks.
Russia collected about $19 billion from oil exports in March, roughly double February, as the Hormuz crisis lifted prices above the Western price cap.
De-escalation in the geopolitical premium on two fronts, with unresolved tails on both. The Iran MOU leaves the HEU stockpile outside the deal and sets a 30-60 day timeline for broader talks; if mine clearance stalls, Brent re-tests $100-110 and the EFS re-widens toward the $6 peak. The EU maritime-services ban remains deferred pending G7 coordination at Kananaskis on 12-15 June; a US-EU split on that ban, structurally plausible given the GL 134C architecture, would leave the dark-fleet cost curve permanently below where the ban would have set it. The GL 134C cliff on 17 June is the nearest binary: a fourth bridge keeps the in-transit market orderly; expiry without a successor forces the same forced-exit dynamic that the market mispriced on 16 May.
