Haycen CEO Luke Sully says some European commodity traders are being “debanked” as Western banks pull back from flows with potential Iran-linked sanctions exposure. He says the retreat is pushing more cross-border settlement onto stablecoins, with USDT the default workaround.
A new compliance squeeze is showing up where liquidity is supposed to be boring: settlement. Haycen CEO Luke Sully said some commodity traders in Europe are being “debanked” as Western banks retreat from certain commodity flows tied to Iran-related counterparty risk.
“Since the war, banks are further retreating from certain commodity flows,” Sully said. “We spoke with some commodity traders who are getting debanked now.”
The mechanism is familiar to anyone who has watched banks de-risk entire categories instead of underwriting edge-case compliance. Sully described bank concerns that transactions that look clean on the surface, including flows involving firms in Oman or other regional hubs, could still carry indirect exposure to sanctioned Iranian entities. When that uncertainty rises, the rational bank response is often to cut the relationship and avoid being the last link in the chain.
When bank rails get pulled, settlement demand does not disappear. It reroutes. Sully said stablecoins are increasingly being used as a workaround for cross-border payments and settlement, highlighting Tether’s USDT as the dominant token absorbing that flow.
“Tether is soaking up a lot of the payments flow,” he said. “If you want to make a one-time payment into an emerging market, USDT is helping.” His explanation is pure market structure: “There is so much global USDT liquidity that people don’t mind sending or accepting it as payment,” he said, “because someone in their country will eventually swap it for dollars.”
That liquidity network effect matters because it turns stablecoins into a stopgap settlement layer for counterparties pushed out of traditional rails. The scale cited for the sector supports the idea that stablecoins can absorb incremental real-economy settlement demand when banks tighten. Stablecoin market capitalization surpassed $300 billion in 2025 after roughly 50% annual growth, with transaction volumes exceeding $4 trillion and representing around 30% of onchain activity.
Sully framed trade finance as a roughly $2 trillion market that has increasingly shifted to non-bank lenders, including private credit funds. “Everybody thinks they know about trade finance, but they don’t,” he said. “It’s predominantly non-bank investment funds lending to borrowers around the world to move goods and services.”
He said these lenders often target annualized returns of around 15% while financing shipments like helium from Qatar to South Korea or manganese from South Africa to Indonesia. The catch is the plumbing: even if financing is non-bank, settlement still leans on banks and correspondent banking networks.
That dependency creates a single-point-of-failure dynamic. If banks retreat from settlement rails for specific corridors or commodity categories, non-bank trade finance can keep underwriting risk but still be forced into alternative settlement methods, including stablecoins.
The immediate problem for market participants is verification. The number of traders affected, the banks involved, and the jurisdictions and corridors seeing the sharpest pullback were not specified.
The cleanest validation would be disclosed examples of European commodity traders losing banking access, including named banks, jurisdictions, or payment corridors. Onchain, sustained increases in USDT transfer volumes and large-value transfers would be more consistent with settlement usage than retail churn, especially if paired with direct commentary from trade-finance participants.
Haycen’s own progress is another measurable signal. Sully said the firm issues a U.S. dollar-backed stablecoin called USDhn and is positioning it as a trade-finance-focused liquidity and settlement layer, adding that it is working with industry participants around the world. Concrete updates on USDhn deployments, new corridors, or settlement volumes would help traders size whether this is a niche wedge or a meaningful carve-out from USDT’s incumbent liquidity.
One more variable is whether sanctions and compliance tightening tied to Iran-related exposure expands to additional commodity categories or regions. Sully also pointed to unspecified “reports” that is being used as a “currency of choice” for payments tied to safe passage through the Strait of Hormuz, but the underlying documentation was not provided.
I treat this as a market-structure story, not a payments narrative. If banks are stepping back from settlement rails for certain commodity flows, stablecoins become the path of least resistance, and USDT is the obvious beneficiary because it already has the deepest distribution and acceptance.
The threshold that matters is evidence of scope: named corridors, repeatable settlement patterns, and onchain flow signatures that look like trade rather than crypto-native recycling. If that holds, the setup starts to look structural rather than narrative-driven, and stablecoins shift from “alternative rails” to “default rails” whenever compliance risk spikes.
