The Office of Foreign Assets Control (OFAC) of the United States Department of the Treasury has added a crypto wallet allegedly connected to a major international crime syndicate to its list of Specially Designated Nationals.
In a Sept. 26 announcement, the U.S. Treasury said it had sanctioned 10 individuals, including many tied to the Sinaloa Cartel. Among those added was Mexican national Mario Alberto Jimenez Castro through an Ethereum wallet.
‘[Jimenez Castro] reports directly to a Chapitos deputy and operates a money laundering organization that uses virtual currency and wire transfers, among other methods, to transfer proceeds from illicit fentanyl sales in the United States to Sinaloa Cartel leaders in Mexico,” said Treasury. “Jimenez Castro has directed U.S.-based couriers to pick up cash in the United States and deposit it into various virtual currency wallets for payment directly to the Chapitos and for reinvestment in fentanyl production.”
According to data from Etherscan, the wallet had a balance of roughly 0.018 Ether (ETH) — $28.22 — at the time of publication, with the latest activity more than 200 days ago. No other wallet addresses were included in OFAC’s most recent sanctions, which the Treasury said were in response to “illicit fentanyl trafficking” affecting the crisis surrounding opioid use in the United States.
“Today’s actions show that Treasury and the Administration will continue to relentlessly target the criminal enterprises threatening international security and flooding our communities with fentanyl and other deadly drugs,” said Brian Nelson, under secretary of the Treasury for terrorism and financial intelligence.

Many industry leaders and policymakers criticized the Treasury’s actions against Tornado Cash. Six individuals backed by crypto exchange Coinbase filed a lawsuit against Treasury over the sanctions, but in August, a judge largely sided with the U.S. government in a motion for summary judgment.
There is “no doubt” the UK “will spend 3% of our GDP on defence” in the next parliament, the defence secretary has said.
John Healey’s comments come ahead of the publication of the government’s Strategic Defence Review (SDR) on Monday.
This is an assessment of the state of the armed forces, the threats facing the UK, and the military transformation required to meet them.
Prime Minister Sir Keir Starmer has previously set out a “clear ambition” to raise defence spending to 3% in the next parliament “subject to economic and fiscal conditions”.
Mr Healey has now told The Times newspaper there is a “certain decade of rising defence spending” to come, adding that this commitment “allows us to plan for the long term. It allows us to deal with the pressures.”
A government source insisted the defence secretary was “expressing an opinion, which is that he has full confidence that the government will be able to deliver on its ambition”, rather than making a new commitment.
The UK currently spends 2.3% of GDP on defence, with Sir Keir announcing plans to increase that to 2.5% by 2027 in February.

This followed mounting pressure from the White House for European nations to do more to take on responsibility for their own security and the defence of Ukraine.
The 2.3% to 2.5% increase is being paid for by controversial cuts to the international aid budget, but there are big questions over where the funding for a 3% rise would be found, given the tight state of government finances.
While a commitment will help underpin the planning assumptions made in the SDR, there is of course no guarantee a Labour government would still be in power during the next parliament to have to fulfil that pledge.

From March: How will the UK scale up defence?
A statement from the Ministry of Defence makes it clear that the official government position has not changed in line with the defence secretary’s comments.
The statement reads: “This government has announced the largest sustained increase to defence spending since the end of the Cold War – 2.5% by 2027 and 3% in the next parliament when fiscal and economic conditions allow, including an extra £5bn this financial year.
“The SDR will rightly set the vision for how that uplift will be spent, including new capabilities to put us at the leading edge of innovation in NATO, investment in our people and making defence an engine for growth across the UK – making Britain more secure at home and strong abroad.”
Sir Keir commissioned the review shortly after taking office in July 2024. It is being led by Lord Robertson, a former Labour defence secretary and NATO secretary general.
The Ministry of Defence has already trailed a number of announcements as part of the review, including plans for a new Cyber and Electromagnetic Command and a £1bn battlefield system known as the Digital Targeting Web, which we’re told will “better connect armed forces weapons systems and allow battlefield decisions for targeting enemy threats to be made and executed faster”.

On Saturday, the defence secretary announced a £1.5bn investment to tackle damp, mould and make other improvements to poor quality military housing in a bid to improve recruitment and retention.
Mr Healey pledged to “turn round what has been a national scandal for decades”, with 8,000 military family homes currently unfit for habitation.
He said: “The Strategic Defence Review, in the broad, will recognise that the fact that the world is changing, threats are increasing.
“In this new era of threat, we need a new era for defence and so the Strategic Defence Review will be the vision and direction for the way that we’ve got to strengthen our armed forces to make us more secure at home, stronger abroad, but also learn the lessons from Ukraine as well.
“So an armed forces that can be more capable of innovation more quickly, stronger to deter the threats that we face and always with people at the heart of our forces… which is why the housing commitments that we make through this strategic defence review are so important for the future.”
