On 23 June the US Treasury blacklisted Banco Financiero Internacional (BFI), Cuba's main foreign currency clearing bank. It also hit three firms tied to GAESA (Cuba's military conglomerate) and a relative of Alejandro Castro Espín.
Six days earlier Havana had legalised private banks and dollar accounts. That bank was the one route most new accounts would use, so the reform now has no dollar pipeline.
