GL 134B out, Rotterdam dark, OPEC+ pending

3 min read
17:30UTC

Three independent squeezes land in one fortnight: OFAC's GL 134B waiver expired 16 May, BP Rotterdam's 400kbd is dark on both crude units, and OPEC+ meets 7 June after a seven-member 188kbd June hike. Brent-Dubai EFS sits above $6/bbl. The trade is in the disconnects, not the headline price.

Key takeaway

The trade is in the disconnects: every stabiliser has exited or broken down simultaneously.

Seven OPEC+ countries agreed a 188,000 barrels per day June hike on 3 May, the first decision taken without the UAE since Abu Dhabi's formal exit four days earlier.

Seven OPEC+ members approved a 188,000 barrels per day June hike on 3 May 2026. It was the first vote taken after the United Arab Emirates formally left OPEC on 1 May. The June increment is far smaller than the 411,000 barrels per day unwinds of April and May.

Saudi Arabia now bears sole responsibility for steadying the Brent forward curve. Without the United Arab Emirates as a second spare-capacity anchor, the 7 June ministerial inherits a thinner buffer. 

OFAC let General Licence 134B expire at 12:01 ET on 16 May with no rollover, two days before fining Adani Enterprises $275m for Iran-LPG violations.

The Office of Foreign Assets Control let General Licence 134B expire on 16 May 2026 without a successor, stripping portfolio-level cover on in-transit Russian cargoes. Two days later, a $275 million Adani Enterprises settlement for liquefied petroleum gas sanctions violations put a dollar figure on commodity-chain enforcement.

Compliance desks lost their portfolio cover and inherited a fresh precedent in the same week. Cap enforcement has migrated from price discipline to individual cargo prosecution. 

Both crude units at BP's 400,000 barrels per day Rotterdam refinery ran offline through May 2026 while ARA gasoil stocks fell to 13.56 million barrels, the lowest since July 2025.

BP ran both crude units at its 400,000 barrels per day Rotterdam refinery offline simultaneously through May 2026. Amsterdam-Rotterdam-Antwerp gasoil stocks fell to 13.56 million barrels, the lowest since July 2025. United States distillate inventories ran 6 per cent below their five-year average in the same fortnight.

One of Europe's largest refining sites reached zero crude throughput just as Atlantic-basin distillate stocks tightened on both sides of the ocean. That binding of supply anchors Northwest European gasoil cracks into June. 

The Brent-Dubai Exchange of Futures for Swaps sat above $6 per barrel through 4-8 May while VLCC freight from the Middle East Gulf to China hit WS458.75 on 11 May.

The Brent-Dubai Exchange of Futures for Swaps stayed above $6 per barrel from 4 to 8 May 2026, triple the pre-conflict baseline. The spread instrument prices the gap between the two crude benchmarks. The Gulf-to-China supertanker route hit 458.75 Worldscale points on 11 May.

Both the crude spread and the freight rate price the same unresolved Hormuz disruption. Until they compress together, the conflict premium stays embedded in Atlantic-basin cargoes regardless of nominal ceasefire status. 

The CFTC's 12 May Commitments of Traders report showed WTI managed money net short -4,723 contracts against ICE Brent managed money net long +58,259 contracts as of 28 April.

The 12 May 2026 Commitments of Traders report from the Commodity Futures Trading Commission showed ICE Brent managed-money net long at plus 58,259 contracts. West Texas Intermediate sat net short at minus 4,723 contracts as of 28 April. The two benchmarks almost never diverge this sharply.

Speculators are long Brent on Hormuz disruption risk and short West Texas Intermediate on OPEC+ supply expectations. A single benign Hormuz headline unwinds the Brent position faster than the other side can recover.

The EIA's 12 May Short-Term Energy Outlook projected Brent at roughly $106 per barrel in Q2 2026, decaying to $89 per barrel by Q4 on the assumption Hormuz partially normalises.

Sources profile:This story draws on neutral-leaning sources

The Energy Information Administration's 12 May 2026 Short-Term Energy Outlook projected Brent at roughly $106 per barrel in the second quarter, falling to $89 by the fourth. The International Energy Agency's May report logged 246 million barrels of global inventory draws across March and April, the second-largest two-month draw on record.

The $17 per barrel negative carry is contingent on Hormuz normalisation no print yet confirms. Aramco's chief executive warned the market may not stabilise before 2027. 

The Druzhba pipeline's southern leg restarted in late April 2026, restoring roughly 175,000 to 200,000 barrels per day of sanctions-exempt crude to MOL and Slovak refiners.

The Druzhba pipeline's southern leg restarted in late April 2026, restoring 175,000 to 200,000 barrels per day of exempt crude to MOL and Slovak refiners. Urals at $76 per barrel against Brent above $100 opened a $40 per barrel feedstock gap, the widest in the sanctions era.

Druzhba crude is exempt from the price cap, maritime restrictions, and the lapsed in-transit waiver. MOL runs feedstock 40 per cent cheaper than seaborne peers, selling into a market priced off tight stocks.

Fujairah total oil inventories fell to a record low 6.5 million barrels in May 2026 as residual fuel oil dropped 27 per cent month-on-month below 3 million barrels.

Fujairah Total oil inventories fell to a record low of 6.5 million barrels in May 2026. Residual fuel oil dropped 27 per cent month-on-month to below 3 million barrels at the world's second-largest bunkering hub. Cape-rerouting tankers drove incremental demand into the port at its leanest moment.

Northwest European gasoil stood at a ten-month low. United States distillates ran 6 per cent below their five-year average. All three basins tightened simultaneously, confirming the post-conflict squeeze is global.

The KSE Institute's April 2026 Shadow Fleet Tracker recorded 194 Russian-port tanker movements in March as the Russian-flagged share of the shadow fleet jumped from 3 per cent to 21 per cent in nine months.

The Kyiv School of Economics April 2026 shadow fleet tracker recorded 194 Russian-port tanker movements in March. The Russian-flagged share of shadow-fleet vessels rose from 3 per cent to 21 per cent in nine months. Russian-flagged tankers sit outside European Union port-inspection and Western protection-and-indemnity reach.

The price cap's core mechanism, Western insurance withdrawal, no longer operates for a fifth of the fleet. Enforcement has moved to commodity-chain prosecution at the buyer's bank, producing precedents one cargo at a time. 

Closing comments

Regulatory and supply-credibility pressure is escalating into the 7 June ministerial on two independent vectors. On the sanctions side: Treasury ruled out GL 134C, the EU 20th package set the legal basis for a full maritime-services prohibition, and OFAC posted a $275m commodity-chain enforcement scalp two days after the waiver expired. The Russian-flagged shadow fleet's share rising from 3% to 21% in nine months pulls vessels out of Western P&I and port-state-control reach, concentrating enforcement on cargo-buyer banks rather than flag-state inspections. On the supply side: Saudi Arabia is the sole OPEC+ spare-capacity anchor after the UAE exit, and the KSE April tracker shows Urals at $76 versus the G7's $47.60 cap, meaning the price-cap revenue-suppression mechanism has failed in favour of an enforcement mechanism whose cost is now anchored at $275m per participant. The tipping point for a change in direction is the 7 June ministerial: if Saudi Arabia signals accelerated unwind beyond 188kbd, Brent faces a structural compression from the supply side that could begin closing the EFS and relieving NWE distillate margins. If GL 134C remains absent through June loadings, the compliance cliff calcifies.

Different Perspectives
Saudi Aramco / Saudi Ministry of Energy
Saudi Aramco / Saudi Ministry of Energy
Riyadh led the seven-member 188kbd June hike, deliberately stepping down from the 411kbd April-May pace to avoid flooding a market already softening on Hormuz-normalisation expectations. Saudi Arabia is now the sole OPEC+ spare-capacity anchor after the UAE exit, so any acceleration risks undercutting the Brent floor that funds Vision 2030 at its $80-90/bbl budget breakeven.

Shell / TotalEnergies NWE refining desks
With BP Rotterdam running zero crude throughput and ARA gasoil at 13.56mb, NWE refiners still operating on full crude runs are capturing composite margins at their highest in over a year. Shell Pernis and TotalEnergies are the marginal price-setters for European product; any turnaround overlap with BP Rotterdam's second crude unit pushes the structural anchor further into Q3.
MOL Group / Slovak refining sector
MOL Group / Slovak refining sector
Druzhba southern leg restart in late April delivered ~175-200kbd of sanctions-exempt pipeline crude to MOL at roughly $40/bbl below NWE seaborne feedstock cost, widening MOL's margin advantage against Rotterdam and Lavera peers. The Druzhba premium persists for as long as the pipeline allocation holds and the EU maritime-services phase-in remains pending G7 coordination.

The GL-134B lapse turns every in-flight Russian cargo after 16 May into a distinct OFAC risk decision; commodity traders holding KEBCO term contracts can no longer manage these as portfolio hedges. The $275m Adani settlement is now the reference enforcement cost, calibrating whether the compliance premium on Russian cargoes exceeds the Urals-Brent discount.
Goldman Sachs London commodity research

Goldman's London energy desk issued a Q4 2026 Brent forecast of $90/bbl on tighter Gulf output from the UAE exit and Hormuz closure, implying $17/bbl of negative carry for anyone buying Q2 forward for Q4 on a Hormuz-normalisation assumption. The forecast aligns with the EIA STEO Q4 print of $89/bbl and sets the sell-side consensus on reversion timing.
OFAC / US Treasury
OFAC / US Treasury
Treasury's decision not to issue GL-134C and to post the $275m Adani settlement two days after GL-134B expired signals a deliberate shift from waiver-based transition management to commodity-chain prosecution as the primary Russia oil-revenue-suppression tool. The enforcement ledger, not the cap number, is now the operative constraint on participation.
