How Stablecoins Become Money: Liquidity, Sovereignty, and Credit

·

Stablecoins are revolutionizing global fintech by offering fast, nearly free, and programmable financial solutions. As traditional finance begins to integrate stablecoins, their growing volumes highlight their potential to reshape monetary systems. However, this transition introduces new risks and challenges, requiring innovative approaches from entrepreneurs, regulators, and financial institutions.

1. The Singleness of Money: Unifying Stablecoins with Traditional Finance

The singleness of money ensures all forms of currency within an economy are interchangeable at par (1:1). This principle simplifies transactions, contracts, and pricing. However, stablecoins currently lack seamless integration into existing financial infrastructure, leading to slippage and market inefficiencies during large conversions.

3. Treasuries as Collateral: Implications for Credit Markets

Stablecoins backed by short-dated Treasuries risk dominating the T-bill market, potentially reducing yields and credit availability. Narrow banking models (100% reserves) limit money multipliers but increase velocity.
