Top Story
The US Office of the Comptroller of the Currency issued a final rule implementing the GENIUS Act on 21 October 2026. The rule covers permitted payment stablecoin issuers and certain custody activities under OCC jurisdiction. It takes effect 18 January 2027.
The rule draws a line on yield. Stablecoin issuers such as Circle remain prohibited from paying interest to holders. Exchanges such as Coinbase and Robinhood can pass interest-like rewards to customers on a "case-by-case basis."
The American Bankers Association accused the OCC of undermining Congress with the rewards rule. The rule did not lift the market. Bitcoin fell below $83,000 on 22 October as AI concerns weighed on sentiment, according to Bloomberg.
