Great.
That will force more and more countries to isolate themselves from the US banking and payment system, especially the EU ones since their official position is that the US is off it's rocker and they don't mind some basic trade with Iran and several companies (French and German banking/insurance conglomerates most notably) have been constantly racketed with insane fines (in billions totals) by the US justice system since they have affiliates of affiliates of subsidiaries locally trading with people that the US doesn't like and since they created the insane precedent that if ANY part of the (gigantic) multinational has transactions in $US (even if said subsidiaries never traded in $US) it makes the whole entity responsible in front of US judges, using specifically designed loopholes in criminal laws (RICO) designed to fight organized crime, instead of commercial laws (were obviously the norm is autonomous subsidiaries are a separate legal entity, it's the fucking basics of capitalism. You create a company that company is responsible of it's own losses not you, or only to some extent, nor any other companies you might own).
All this does is weakening the grip of the US empire and demonstrate it's complete impotence by literally forcing companies to abandon the US dollar by creating "firewalled" branches that will never use it (and will only ever conduct trade in local currency and international trade in yen/euros/yuan).
Here an example:

AXA is a very old insurance company (200+ years) that is easily on the top 3 of banking/insurance transnational company (other 2 would be the British Barclays and the US State Street that are just as old and enormous). Besides North Korea there is probably not a country on the fucking planet they don't have some kind of activity.
Bunch of guys get (arbitrarily) to a sanction list in the U.S. Treasury Department Office of Foreign Assets Control (which has 0 power of law enforcement or inquiry. 99% of the time it's a politician deciding to get votes and look tough on X or Y issue).
They have standing prior life insurance policies in one of the myriad of companies AXA has parts in.
Three years later, just as arbitrarily (they weren't arrested or anything), those guys are removed from the list.
Of course no-one notices, why the fuck would a insurance case agent in Mexico check a list made by an obscure agency in another country against the ENTIRE existing client database, retroactively?
Then some US fed, years latter, no doubt using the total surveillance of datastream the US can obtain in complete illegality and feed them through the NSA supercomputers, realize that those guys had insurance contracts with a company that is a tiny speck of a bigger one that they can racket (IE not US), kicks it to a prosecutor friend for career advancement, US subsidiary of a multinational (completely unrelated to the whole thing) ends up with a $20M fine (that is probably 10 times the actual life insurance policies).
Now this is just an example, imagine that this shit is happening basically EVERY TIME they put someone on one of those list (terrorism, narcotraffic, organized, crime, might have had lunch with Putin, etc…) your looking at those fine raining down on major companies on a weekly basis.
Now you could say "well it's incentive for foreign companies to stop and check their entire worldwide operations every-time a US senator's aide has a stick up his bum about someone" but the truth is that everyone has realized that it's a mint for the US justice department… so of course it's not gonna stop anytime soon.
So what is happening is the exact opposite. Companies are taking steps to continue their operation unhindered by the US.
Which means that the US is spending it's economical warfare capital on RETARDED BULLSHIT and actively incentivize the rest of the planet to build the economical system AROUND the US.
