Mercury vs Mercury Treasury vs Mercury Personal

Mercury launched Mercury Personal in 2024 to serve individual non-residents. They have always had Mercury Business for LLCs and Mercury Treasury as a yield feature. Three products, three different fits. Here is what each does and which your Wyoming LLC needs.

Answer

Mercury Business: business checking account for your Wyoming LLC. Required. Approval ~70% for non-resident LLCs. Mercury Treasury: yield feature within Mercury Business (T-bill sweep, ~5% APY). Optional add-on. Mercury Personal: individual non-resident checking account separate from any LLC. Not for businesses. Most non-resident Wyoming LLC owners need Mercury Business + optionally Mercury Treasury.
