IMF just dropped a warning that's got policymakers nervous: stablecoins might be eating into central banks' ability to control their own monetary systems. The concern? As more people park their funds in dollar-pegged or crypto-backed stables, traditional banking channels lose grip on money supply management. Think about it—when billions flow into USDT or USDC instead of sitting in regulated bank accounts, central banks can't deploy their usual tools like interest rate adjustments as effectively. It's not just about adoption numbers anymore; it's about financial sovereignty being quietly challenged by decentralized alternatives. IMF's stance signals that regulators worldwide are waking up to this shift, but whether they'll adapt or resist remains the multi-trillion dollar question.
