According to Bloomberg, S&P Global Ratings has downgraded Tether’s USDT stability assessment from “Constrained” to the lowest tier, “Weak,” citing a higher allocation to riskier reserve assets and limited transparency. S&P said bitcoin now represents about 5.6% of USDT’s circulating supply, surpassing its 3.9% overcollateralization buffer, and warned that a drop in bitcoin or other high-risk assets could leave reserves insufficient to fully cover outstanding tokens. https://t.co/W9UbaUu1Oz ...
