The U.S. Treasury Department said in a report that cryptocurrencies could undermine the effectiveness of U.S. sanctions.

  • The report was released Monday. It followed a six-month review of U.S. sanctions against countries with which it is at odds or suspects of being behind illegal activity.
  • The report noted that “digital currencies, alternative payment platforms and new ways of hiding cross-border transactions all potentially reduce the efficacy of American sanctions.”
  • “These technologies offer malign actors opportunities to hold and transfer funds outside the traditional dollar-based financial system,” the report said, and could be used by adversaries “to to build new financial and payments systems intended to diminish the dollar’s global role.”
  • The U.S. has put over 9,000 sanctions in place against countries it alleges are behind terrorism and illegal actions or committed human rights violations, including North Korea and Iran, according to a New York Times story.
  • The report recommended the Treasury Dept. enhance its “institutional knowledge” of cryptocurrencies and their use.
  • It also recommended the agency improve its communications with industry organizations, financial institutions and others that touch on the crypto sector.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.
