A seemingly trivial 0.​1% fee becomes significant at scale.​ On a $500,000 payment, it's just $500.​ But applied to the $145 trillion annual volume of cross-border wholesale B2B payments, that 0.​1% translates to $145 billion per year.​

The Stablecoin Solution

Stablecoins are emerging as an efficient alternative for global payments:

  • Payment volumes projected to reach $1 trillion annually by 2030
  • B2B payments currently represent ~$36 billion annually, about 50% of stablecoin flows
  • DeFi protocols turnover capital 11x per month vs.​ 1-2x for traditional fintechs

Idle Capital Problem

21% of US commercial deposits ($3.​85 trillion) earn zero yield.​ Stablecoins are already distributing $600M+ through yield-bearing assets, putting idle business funds to work.​

Macro Impact

At $2 trillion supply, stablecoins could hold close to 25% of the Treasury bill market.​ They may reach 10% of US M2 supply by 2030 (vs 0.​04% in 2020)鈥攐ne of the biggest shifts in money this decade.​

The analysis breaks down where traditional payment fees go and how blockchain-based stablecoins eliminate intermediaries and friction costs.​
