Dec. 31 — The U.S. Financial Accounting Standards Board (FASB) plans to explore in 2026 whether certain stablecoins qualify as "cash equivalents" and study accounting for cryptocurrency transactions (including wrapped tokens), according to The Wall Street Journal. The move comes amid the Trump administration’s push for crypto policies and the passage of the U.S. Stablecoin Innovation Act (GENIUS Act).
