The business model of traditional B2B large payment institutions is based on "information asymmetry" and "opaque pricing", with many institutions quoting and matching transactions through phone calls. Customers cannot easily compare prices, and banks enjoy profits from information monopolies, where relationships and trust are more important than efficiency. So: -Banks will not actively promote stablecoins for B2B large payments because it would eliminate their source of profit -Customers may not necessarily want transparency, especially in forex trading where large clients may obtain better prices through relationships -Regulatory agencies may also not want excessive transparency as it could affect market stability But under the explosive trend of stablecoins, will a "rolling king" suddenly emerge to break this pattern? What kind of institution is most profitable in this changing situation?
