Brent Holds $100 as Ukrainian Drones Knock Out 40% of Russia's Oil Exports

Russia's Export Collapse

Ukrainian drone strikes have knocked out approximately 40% of Russia's oil export capacity — roughly 2 million barrels per day — according to Reuters calculations published Wednesday. Reuters called it the "most severe oil supply disruption" in modern Russian history.

The damage spans Russia's entire western export network. Loadings at Primorsk and Ust-Luga, Russia's two largest Baltic Sea terminals, were suspended again this week after a second round of drone attacks triggered fires at port infrastructure. In the Black Sea, Novorossiysk — with capacity of around 700,000 barrels per day — is running behind its loading schedule from earlier strikes. The Druzhba pipeline, Russia's overland route to Hungary and Slovakia via Ukraine, has been effectively offline since January.

At least 50 tankers are now stacked offshore in the Gulf of Finland with nowhere to load. Russia's remaining functional export routes — pipelines to China and the Pacific port of Kozmino — carry roughly 1.9 million barrels per day, meaning Moscow can still supply its most important buyer but has lost most of its access to the global seaborne market.

The timing is brutal. This is hitting alongside the Hormuz closure, creating the first simultaneous disruption to both of the world's major oil export corridors in decades.

Hormuz Gets a Yuan Toll Booth

While Ukraine reshapes Russia's export picture, the Strait of Hormuz is evolving from a blockade into something arguably more disruptive: a toll regime.

Iran allowed 10 oil tankers through the Strait this week — a "present" to the United States, according to President Trump — but the gesture came with strings. Lloyd's List Intelligence reported that at least two vessels paid transit fees settled in Chinese yuan, with Iran requiring manifests, crew details, and destination information for what it described as "sanctions screening" and "geopolitical vetting." An Iranian lawmaker framed it plainly: "We provide its security, and it is natural that ships and oil tankers should pay such fees."

Trump extended his pause on striking Iranian energy infrastructure by 10 days to Monday, April 6, characterizing negotiations as "going very well." Iran's Foreign Minister Araghchi reiterated that Tehran has no intention of negotiating. The gap between the two sides isn't narrowing.

The de-escalation trade that flushed Brent into the mid-$90s earlier this week keeps getting faded. Each round of optimism — Trump's initial pause, the 15-point plan, now the extension — gets met with an Iranian rejection, and the war premium returns.

The Inventory Headwind

The EIA's Weekly Petroleum Status Report dropped a bearish number into this bullish setup: U.S. crude inventories rose 6.9 million barrels for the week ending March 20, against expectations of a 0.5 million-barrel build. It was the fifth consecutive weekly increase. Cushing, Oklahoma — the WTI delivery hub — added 3.4 million barrels alone, the largest weekly build there since January 2023.

The inventory picture explains why Brent's move has been more measured than the headline geopolitics might suggest. Bank of America raised its 2026 Brent forecast to $77.50 from $61, but their base case still assumes flows normalize by April — a scenario that looks increasingly detached from reality given Iran's posture and Russia's crippled export network. Nearly 200 million barrels have already been removed from global supply through the Hormuz disruption alone, erasing about half of last year's 400-million-barrel inventory build.

The macro tension is clear: physical supply is getting tighter by the week, but U.S. domestic storage is swelling because crude at $100+ is destroying demand faster than disruptions can tighten the market. Something has to give.
