Central banks are increasingly expressing concerns about stablecoins, viewing them as a more significant threat to the traditional financial system than Bitcoin. This sentiment is well-founded, as stablecoins, which are designed to maintain a stable value by being pegged to a reserve asset or currency, have the potential to disrupt monetary policy and financial stability. Unlike Bitcoin, which is often seen as a speculative investment and store of value, stablecoins can facilitate seamless digital transactions and provide a convenient medium of exchange. As their adoption grows, central banks worry that these digital currencies could undermine their authority, challenge the effectiveness of existing monetary policies, and increase the risk of financial instability, leading them to take a cautious approach towards the regulation and integration of stablecoins into the broader economy.
