US Crypto Week: Treasury Sanctions BitBank as Coinbase Brings Crypto to Community Banks

Two developments from the past few days show where the US crypto market is heading. Enforcement is reaching deeper into offshore infrastructure, and regulated banks are reaching into crypto. Both are steps toward the same outcome: a digital-asset market that operates inside the compliance perimeter.

Treasury Targets Iranian Exchange BitBank

On Thursday, September 17, the US Treasury's Office of Foreign Assets Control (OFAC) sanctioned the Iranian crypto exchange BitBank. It also designated the exchange's software developer, Pishtaz Simorgh Electronic Trade Company, and three associates of the financier Babak Zanjani.

Treasury alleges that between June and July, Zanjani used BitBank to move hundreds of millions of dollars' worth of Bitcoin to Iran's Islamic Revolutionary Guard Corps. It also says the previously sanctioned Hormuz Safe platform has used the exchange since June to route payments to the Iranian government. The designations fall under Executive Order 13902 and are part of Operation Economic Outcast. Treasury Secretary Scott Bessent said that funding the Iranian regime through crypto is not beyond OFAC's reach.

Some context matters here. These are administrative sanctions, not criminal convictions. Treasury's announcement did not publish wallet addresses, transaction hashes or a precise total, so the "hundreds of millions" figure remains the government's own claim. For US persons, the practical effect is that any BitBank-linked property must be blocked. Foreign firms that deal with the designated parties may face secondary sanctions exposure.

Coinbase and Stablecore Bring Crypto to Community Banks

On September 16, Coinbase announced a partnership with the banking technology provider Stablecore. The goal is to let community banks and credit unions offer crypto trading, custody, staking and stablecoin payments inside their existing digital banking platforms.

The division of labor is simple. Coinbase supplies the custody and exchange infrastructure, and Stablecore connects it to each institution's core banking, digital banking and compliance systems. The model is white-label, so banks keep their own branding and customer experience. Amarillo National Bank is among the early institutions involved.

The headline figure needs a careful reading. Stablecore's existing integrations reach systems used by more than 3,000 US banks and credit unions, but that is the size of its technology footprint, not the number of banks that have signed up. The deal also follows a separate Coinbase partnership with Moov, announced on September 10, which covers stablecoin settlement for more than 1,000 community institutions.

Two Stories, One Direction

At first glance, a sanctions action and a banking partnership have little in common. Read together, they describe the same shift. Regulators are tightening the rules for platforms outside the US financial system. Meanwhile, regulated firms are building compliant on-ramps for the platforms and customers inside it.

For banks, the appeal is straightforward. Smaller institutions can offer digital-asset services without building custody and trading systems from scratch. For the broader market, the enforcement side is a reminder that compliance is becoming a condition of access rather than an optional extra.

What to Watch Next

Institutional demand remains visible. US spot Bitcoin ETFs recorded about $159 million in net inflows on Thursday, led by BlackRock's IBIT. On the policy side, the CLARITY Act stalled in the Senate this week, and the CFTC has sent its crypto market rules to the White House for review. Readers should watch how many banks actually go live with Coinbase services, and whether Treasury extends its Iran-focused campaign to more digital-asset platforms.
