| Banks are not in charge of policing the world.
I never claimed that they were. If HSBC wants to transfer money between (e.g.) Turkey and Iran, then the US has no say, even if they don't like it. | If the US wants to stop funds/goods from
| leaving/ending up in Iran they should stop those
| funds/goods from entering/leaving the US in the
| first place.
This is a straw-man. I'm not talking about attempting to prevent every possible thing that ever leaves the US from ever entering Iran under all possible circumstances. That's obviously impossible.The article paints a picture that HSBC provided the service of routing money around so that people in Iran could transfer money to the US and vice versa. The entire purpose of this service would be to obfuscate the origin or destination of the transfer from the US government.
I wouldn't say that requiring HSBC to not do this would be requiring them to 'police the world,' but if they want to be chartered as a bank in the US, it certainly makes sense that they should 'play by the rules.' If they were specifically offering/advertising a service to clients where-by they would actively skirt those rules, it doesn't seem like there is an issue with (at the least) revoking their charter.
