Iran overtakes Russia as the top target of US sanctions

Iran overtakes Russia as the top target of US sanctions

Force in Play

New designations flipped from Russia to Iran in 2025, but a naval blockade, not the list, is what cut Iran's oil exports

Today: Tracker shows Iran overtaking Russia in new designations

Overview

Updated 40 minutes ago

For three years, the US Treasury's sanctions list grew mainly in one direction: Russia. Since April 2025 that has flipped. Treasury has added 1,574 names under Iran programmes and 51 under Russia programmes, according to a compilation of every OFAC list-change file published through November 6, 2026.

Russia still holds more names overall, 6,809 to Iran's 4,114. What changed is the flow. The Iran campaign is a steady drip of tankers, traders and shell companies. The Russia campaign has largely stopped, and the one measure that actually cut Iran's oil exports was a naval blockade, not the list.

Why it matters

Every new name adds screening work and cost for banks, insurers and shippers touching Iranian oil, even indirectly.

Scenarios

1

Iran designations keep coming at the current pace through mid-2027

Likely Resolves by Q2 2027

Discussed by: WarBrief's sanctions tracker, which counts every OFAC change file

Treasury has added Iran-programme names in almost every quarter since April 2025, mostly ships, traders and shell companies. If the campaign continues, the Iran stock on the SDN list keeps climbing toward Russia's total while the screening burden for banks and shippers grows.

2

Russia designations resume as the Graham Act is reactivated

Possible Resolves by Apr 30, 2027

Discussed by: Cleary Gottlieb, which notes the waiver can be reversed at any time

The October 2026 executive order suspends the Russia provisions of the Graham Act but preserves existing designations. The president or secretary of state can determine that further action is appropriate, which would bring the law's measures back into force and restart large Russia packages.

3

Blockade lifts and Iranian exports recover without the list changing

Uncertain Resolves by Q1 2027

Discussed by: Vortexa and Kpler tanker-tracking data cited by WarBrief

Iran's exports fell only after the naval blockade began in April 2026, and they stayed low while it was enforced. If the blockade ends or is paused for good, loadings could climb back toward pre-blockade levels even with the designations still in place, repeating the 2025 pattern when exports hit a yearly high despite record designations.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

May 2018 – January 2021

Iran maximum pressure, first term (2018–2020)

The US withdrew from the 2015 nuclear deal and reimposed sanctions on Iran's oil and banking sectors, with a stated goal of zero exports. Treasury built the campaign around shipping networks, traders and front companies, the same playbook now in use.

Then

Iran's oil exports fell sharply and its currency weakened, but the government stayed in power and kept selling crude through informal channels.

Now

The campaign ended without a follow-on agreement, and Iran expanded its nuclear programme. The designations raised the cost of trade but did not stop it.

Why this matters now

The current campaign repeats the first-term approach, with one addition: a naval blockade that did what the list alone had not.

February 2022 – January 2025

The Russia sanctions surge (2022–2025)

After the full-scale invasion of Ukraine, Treasury and the State Department released large Russia packages tied to symbolic dates, including 551 names in February 2024 and 406 in January 2025 covering Gazprom Neft, Surgutneftegas and 183 vessels.

Then

Russia became the largest single programme on the SDN list, with 4,706 names added between late 2022 and early 2025.

Now

The flow stopped almost entirely in 2025 as the administration pursued a deal. An independent count found 74 Russian persons added that year, against roughly 1,500 a year previously.

Why this matters now

It shows how fast a sanctions programme can reverse direction, and why the stock of names and the flow of new ones tell different stories.
