Unlike traditional banks that lend deposits multiple times, USDC is a 'full reserve' system. Every digital dollar is backed 1-to-1 by cash and short-term treasuries, eliminating lending risk. This 'narrow banking' model, now enshrined in law, offers a fundamentally safer financial instrument.

Despite being a latecomer, Japan's regulatory framework is setting a global precedent. Its strict requirements—such as 100% backing by high-quality liquid assets and a ban on algorithmic stablecoins—are being mirrored by other major financial centers, positioning Japan's model as the new standard for trust and stability.

Banks oppose stablecoins because they disrupt a core profit center: the spread between low interest paid on deposits and high yields earned from investing those deposits in treasuries. Stablecoins can pass these yields directly to consumers, creating a competitive market.

By creating a regulatory framework that requires private stablecoins to be backed 1-to-1 by U.S. Treasuries, the government can prop up demand for its ever-increasing debt. This strategy is less about embracing financial innovation and more about extending the U.S. dollar's lifespan as the global reserve currency.

The US government's backing of stablecoins is a strategic financial maneuver, not just a nod to crypto innovation. By promoting stablecoins backed by US Treasuries, it creates a new, frictionless global distribution channel to sell its debt at attractive rates to a worldwide audience.

To extend the solvency of U.S. debt, create a one-to-one stablecoin backed by treasuries. This would grant global citizens, particularly in countries with unstable currencies, a direct way to save in a dollar-denominated asset. This new demand could lengthen the runway for U.S. fiscal policy.

Contrary to the belief that high rates boost revenue from reserves, Circle's CEO reveals lower rates fuel stablecoin adoption. High rates increase the opportunity cost of holding non-interest-bearing cash, whereas lower rates encourage capital velocity and investment in new technologies, expanding the market.

The stablecoin market isn't about everyone launching their own coin. Established players like Circle's USDC create powerful network effects through tens of thousands of API integrations with apps like Cash App and Coinbase. This utility makes it the default choice for developers, creating a significant competitive moat.

Before stablecoins, launching financial services in N countries required N² unique integrations. Now, companies can build on a single dollar-stablecoin standard and instantly operate globally. Adding other local stablecoins becomes a simple N-style addition, radically simplifying global expansion.

While stablecoins gain attention, tokenized deposits offer similar benefits—like on-chain transactions—but operate within the existing, trusted regulatory banking framework. As they are simply bank liabilities on a blockchain, they may become a more palatable alternative for corporates seeking efficiency without regulatory uncertainty.

To avoid being classified as a bank, Coinbase's stablecoin model offers "rewards" for user activity like payments or trading, rather than paying interest directly on balances. This is a crucial legal distinction under new regulations allowing them to pass on yield from treasury reserves.
