Payments Industry

What if the $300 billion extracted annually through interchange fees isn't the real opportunity — and the $25 trillion in B2B cross-border flows is?

5P Pillar Coverage

All five pillars present.

The Spine​

  • Principles — route around behavior, reclaim friction; five immutable truths
  • Performance — EBITDA lift, settlement velocity, and spread diagnostics
  • Protocols — stablecoin routing and off-ramp arbitrage flows
  • Platform — the ABCD stack for value flows
  • Players — card networks, stablecoin rails, and treasury CFOs

Zoom Out​

Payments is moving from extraction to efficiency. Stablecoin rails cut the interchange tax from 2-3% toward 0-1.5%, collapse five-day correspondent hops to minutes, and expose hidden FX spreads.

The alpha sits in B2B treasury, not consumer checkout — mid-market companies with $30M+ cross-border exposure can recover 10-20% of EBITDA. Mastercard's Verifiable Intent and Coinbase's x402 are crystallizing the agentic payments stack. The loop compounds: better routing, lower friction, more capital velocity, more treasury optimization, better routing.

Context​

  • Stablecoins — the settlement instrument, from extraction to efficiency
  • Sui — sub-second settlement at machine tempo for agent commerce
  • Agent Commerce — the standards war for agent transactions
  • AP2 + x402 — authorization and settlement for agents
  • Three Flows — messages, money, and data converge
  • Payment Rails — platform architecture

Questions​

When routing intelligence can reclaim billions in hidden friction — who builds the least-cost router for money, and who owns the routing table?

  • Which payments friction — FX spread, settlement delay, or compliance overhead — is most ready to be eliminated by on-chain coordination in the next 24 months?
  • If the Three Flows converge on a single rail, which incumbent industry — banking, telecom, or fintech — loses the most revenue?
  • At what transaction volume does a crypto payments network become cheaper than Visa/Mastercard for a merchant — and what prevents that from being the default today?

Changes my mind: evidence that B2B treasurers won't adopt stablecoin rails despite the EBITDA recovery would break the efficiency thesis.

Next question: which friction clears the first profitable mid-market treasury deployment?
