Iran Oil Exports for October 2025: Continuing at Scale

UANI tracked an estimated total of 6.86 billion barrels (averaging 2.2 million barrels per day BPD) in physical exports out of Iran during October 2025, another new high for the year. The estimated value of exported oil for October is $4.4 billion. The total for 2025 through October is $38.8 billion. 

These record exports for 2025 most likely are linked to strategic stockpiling while crude prices are at record lows.

October Oil Volumes Confirm Iranian Exports Maintain Critical Pace and Indicate Chinese Stockpiling

UANI’s tracking shows 66.8 billion barrels exported in October, an average of 2.2 million barrels per day BPD, translating to roughly $4.4 billion in monthly export value. This is a substantial revenue stream that sustains Iran’s military-industrial complex and overseas proxies.

The lion’s share of Iranian crude moves through Kharg Island and onward to China, with an estimated 80–90 percent of exports landing in Chinese hands.  Spikes prior to the snapback of United Nations sanctions are consistent with deliberate stockpiling behavior ahead of renewed multilateral constraints. The pattern is clear: volumes were increased to pre-position crude in Chinese storage and refineries, insulating Tehran from immediate revenue shocks.

In response, U.S. Treasury Department sanctions designations in October 2025 targeted China-based buyers and terminals (including independent “teapot” refineries and crude terminals).  These designations demonstrate a concrete sanctions evasion network in which ghost fleet tankers, along with Chinese refiners and terminals, enable Tehran to continue generating revenue in the face of snapback sanctions.

UNSC Snapback Sanctions: Legal Clarity Meets an Enforcement Vacuum

The reimposition of UN sanctions on September 28, 2025, restored the core pre-JCPOA prohibitions, including the arms embargo and restrictions on ballistic missile and UAV development. The cover that diplomatic ambiguity provided for evasive actors has been removed. Compliance with snapback sanctions is now a legal obligation for every Member State.

Tehran’s posture has not shifted to match that legal reality. On the contrary, Iran publicly announced it will not recognize the E3’s invocation of snapback. 

Legal restoration without enforcement is only symbolism. Restoring sanctions is only the first step. The operational work of enforcement—the UN Sanctions Committee and the independent Panel of Experts that investigate, document, and recommend action—have yet to be fully reconstituted, with Russia and China likely to resist. UANI is watching the formation process closely.

This political stalling creates an immediate institutional gap. Where the UN bodies are delayed or blocked, individual Member States cannot wait. They must step into the vacuum with national measures, intelligence sharing, and targeted regulatory action.

New Tool for Enforcement: Malaysia’s Commitment to Sanctions Cooperation

Malaysia is not a bystander in Iran’s oil smuggling network. Approximately 70 kilometers offshore of Malaysia lies the global hotspot for ship-to-ship (STS) transfers of sanctioned Iranian oil. In a recent article published in the Diplomat, UANI CEO Ambassador Mark D. Wallace and UANI Chairman Governor Jeb Bush explain that by overlooking illicit STS transfers of blacklisted Iranian oil within its waters and EEZ, “Malaysia has become a silent enabler” of Iran’s illicit oil trade. In October 2025 alone, UANI observed 68 STS operations in Malaysian waters (Eastern Out of Port Limits/EOPL) involving vessels linked to Iranian exports. These transfers are classic evasion tactics: dark rendezvous, false papers, and subsequent reflagging or renaming that blur origins.

The Agreement Between the United States of America and Malaysia on Reciprocal Trade, signed in October, contains powerful enforcement language. Under Article 5.2, Malaysia agreed to cooperate with the United States on controlling trade in goods and technologies that raise national-security concerns—and, crucially, to regulate transactions involving parties on Treasury’s OFAC SDN and Non-SDN Consolidated Lists.

This instrument gives the U.S. government and Malaysia a bilateral lever to act where multilateral mechanisms lag. It creates a legal and cooperative pathway for Malaysia to: (1) police STS rendezvous in its EEZ/EOPL; (2) deny port or bunkering services to vessels involved in sanctioned transfers; and (3) align financial oversight with OFAC lists to cut off the shadow-banking rails.

The critical maritime enforcement role Malaysia can play in disrupting illicit STS transfers is equally consequential to the vital task of combating the extensive financial networks enabling Iran’s sanctions evasion.

FinCEN Exposes the $9 Billion Scale of Iran’s Shadow Banking and Sanctions Evasion Networks

The U.S. Financial Crimes Enforcement Network (FinCEN) Financial Trend Analysis Iranian Shadow Banking: Trends in Bank Secrecy Act Data, published October 23, 2025, quantified the financial side of this issue. Roughly $9 billion in potential Iranian shadow-banking activity flowed through U.S. correspondent accounts during 2024. Those flows are central to the mechanics of sanction evasion—from sale and receipt of proceeds to laundering and onward transfer to fund weapons, UAV programs, and proxy operations.

FinCEN’s analysis highlights a geographically dispersed but tightly integrated infrastructure: corporate fronting and shell companies operating through the UAE, Hong Kong, and Singapore, with shell companies alone transacting about $5 billion in 2024. The lifecycle is systematic: sell the oil, route proceeds through shell companies and complex financial corridors, and then reinvest or move funds through trade and financial intermediaries, often with final consumption or processing in Chinese teapot refineries.

This is an ecosystem. Disable one node and revenue will reroute around it unless enforcement is broad, coordinated, and swift.

Accountability Now

What we know: 

Snapback restored universal legal prohibitions. Yet Tehran is still moving approximately $3.5 billion a month in crude, mainly to China, enabled by a $9 billion shadow-banking network and routine STS transfers in regional hubs like Malaysia.

What must happen next: 

Immediate bilateral and plurilateral enforcement: States with jurisdiction, particularly Malaysia, Singapore, Hong Kong, and the UAE, must use national law and the new U.S.–Malaysia agreement to act now, not later.

Aggressive maritime measures: Implement de-flagging and port/state control actions against vessels credibly implicated in STS operations for Iranian crude, and deny port services, bunkering, and insurance to vessels on proven evasion runs.

Financial countermeasures: Align correspondent banking scrutiny and trade finance controls with OFAC and FinCEN findings, and shut down shell-company pipelines detected in the FinCEN analysis.

Intelligence sharing and prosecution: Move from designation to interdiction—share actionable intelligence across jurisdictions, seize illicit cargo where lawful, and prosecute facilitators.

Use bilateral treaties as force multipliers: The U.S.–Malaysia agreement is a model. Similar bilateral commitments should be pursued to create legal synergies where UN institutional processes are stalled.

UANI calls on governments to convert law into action now. The intelligence exists, the legal framework is in place, and the moral imperative is obvious: dismantle the revenue streams that sustain proliferation and proxy violence, before the next tranche of Iranian oil profits is converted into weapons and terror.
