The business model of traditional institutions for B2B large payments is based on "information asymmetry" and "opaque pricing," with many institutions quoting prices and matching transactions through phone calls.

Customers cannot easily compare prices, and banks enjoy the profits brought by information monopoly; in this context, relationships and trust are more important than efficiency.

So:
- Banks will not actively promote stablecoins for B2B large payments, as this would eliminate their profit sources.

- Clients may not really want transparency, especially in foreign exchange trading, where large clients might obtain better prices through connections.

- Regulators may also not want excessive transparency, as it could affect market stability.

But with the explosive trend of stablecoins, will a "roll king" suddenly emerge to break this pattern? Which types of institutions will profit the most from this change?
