Why? Brokers could be regulated by the FCA (Financial Conduct Committee) if they are in the UK, and AFSL (Australian financial services licence) if they are in Australia. The FX brokers outside the USA offer CFD products that are not allowed here (USA), so many would not choose to be located here let alone regulated here. They have good companies in both locations, but sadly some do open accounts in places where most people would not be able to locate on a map (unregulated or lack any serious regulation).
