Gate News message. On April 12, according to CoinDesk, as the escalation of the U.S.-Iran geopolitical conflict raises concerns, Western banks, worried about compliance and sanctions risk, are accelerating their withdrawal from portions of large-scale commodity trade finance businesses, leading to traders being “debanked” and starting to shift toward stablecoins for cross-border settlement. Banks worry that trades that appear to be compliant could indirectly expose them to sanctioned entities, so they choose to directly contract or even exit trade finance exposure in relevant regions, causing traditional financial payment and settlement channels to keep tightening. Stablecoins—especially USDT, which is pegged to the U.S. dollar—are becoming an alternative settlement tool, with increasing usage in trade payments in emerging markets. Data shows that the market value of stablecoins has exceeded $300 billion, on-chain transaction volume is over $4 trillion, accounting for about 30% of overall on-chain activity.
