The Forex market is very similar to the stock market with the only difference that it's very big both financially and by traded volumes as well. Normally the big banks from all over the world are the key players of the Forex market. Banks like HSBC, Morgan Stanley, and Bank of America etc are the key players or the movers and the shakers of the Forex market.
If you feel that you ought to be a part of this huge trades that are being done daily and the 2 trillion USD market then your interest would be best protected if you happen to get in touch with one of the banks as they would help you place the trades. If you keep watching the market for some time, I'm sure that you would not need much time for yourself to figure out what is hot and what is not. In other words where to invest your money in and what to stay away from.
The international banks and the huge MNC organizations are the key players in the Forex market. They have millions of dollars with them and thus they invest a part of the money and for them its just one way that they happen to use, to work out the interest amount that works out as payable to the account holders of their bank and create money and value for their share holders. In case you are traveling to a different country and you wish to pull out cash from your account but from a different bank in that country, this facility would be available to you if only your bank is a part of the Forex trading market. Otherwise in case you wish to have that information for yourself you might just approach the manager in the bank for the information or look at the quarterly reports published by the banks. That is where they are most likely to be mentioning the amounts of profits or losses that they have made on account of the trades that they had done in the Forex market.
There is no one person or thing that governs over the Forex market. It's mainly governed by situations which are normally out of reach of common people, like the economy of the country or the political situation of the country. And thus there is no fear of insider trading in the Forex market.
