But where is this underlying spot market located?
Obviously, if it is located within the US boundaries, it kinda makes sense. For example, there's a sugar spot market along with sugar futures, but does it mean that the CFTC has jurisdiction over sugar spot market somewhere in Shanghai, or elsewhere outside the US? This is meaningless as they don't have jurisdiction there by any means possible.
that's not how jurisdiction works. you know that 110 countries will extradite to the USA, right? bitfinex and tether immediately responded to the subpoenas because the USA is in a position to fuck them.
it doesn't matter where the activity occurs if the united states has
mutual legal assistance treaties with relevant governments---
MLATs, which are negotiated by the Department of State in cooperation with the Department of Justice to facilitate cooperation in criminal matters, are in force with the following countries: Antigua & Barbuda, Argentina, Australia, Austria, the Bahamas, Barbados, Belgium, Belize, Brazil, Canada, Cyprus, Czech Republic, Dominica, Egypt, Estonia, France, Germany, Greece, Grenada, Hong Kong, Hungary, India, Ireland, Israel, Italy, Jamaica, Japan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, Morocco, the Kingdom of the Netherlands (including Aruba, Bonaire, Curacao, Saba, St. Eustatius and St. Maarten), Nigeria, Panama, Philippines, Poland, Romania, Russia, St. Lucia, St. Kitts & Nevis, St. Vincent & the Grenadines, South Africa, South Korea, Spain, Sweden, Switzerland, Thailand, Trinidad & Tobago, Turkey, Ukraine, United Kingdom (including the Isle of Man, Cayman Islands, Anguilla, British Virgin Islands, Montserrat and Turks and Caicos), Uruguay, and Venezuela. In addition, on February 1, 2010, 27 U.S.-EU Instruments/Agreements/Protocols entered into force that either supplement existing MLATs or create new mutual legal assistance relationships between the United States and every member of the EU.
In addition to MLATs, the United States has a Mutual Legal Assistance Agreement (MLAA) with China, as well as a MLAA between the American Institute in Taiwan and the Taipei Economic and Cultural Representative Office in the United States. The United States also has entered into a few executive agreements on forfeiture cooperation, including: an agreement with the United Kingdom providing for forfeiture assistance and asset sharing in narcotics cases; a forfeiture cooperation and asset sharing agreement with the Kingdom of the Netherlands; and a drug forfeiture agreement with Singapore. The United States has asset sharing agreements with Canada, the Cayman Islands (which was extended to Anguilla, British Virgin Islands, Montserrat, and the Turks and Caicos Islands), Colombia, Ecuador, Jamaica, Mexico, and Monaco.
bitfinex will bank where it can facilitate international bank wires. they can't facilitate money transmission from chinese banks, so they won't bank there. storing all their money in north korea or iran won't help either. their money is likely banked in multiple jurisdictions, some of which are reachable by the long arm of the USA law. this is why we can't fault btc-e for losing so much funds last year. their money processors (mostly run by mayzus) were based in the UK.
If Bitfinex excludes the US residents from trading Bitcoin, it is beyond the jurisdiction of the CFTC. Of course, this doesn't in the least prevent Bitfinex from being seized by the FBI under whatever pretext (as it happened to BTC-e) but then the CFTC would have nothing to do with that. It may oversight Bitcoin markets as well as altcoins but only those in the US as far as I understand it
as pointed out above, that's absolutely not how the CFTC views its mandate. they are not restricted to US markets whatsoever.
in fact, the CFTC is charging 1broker in this case. 1broker is an "international" site with CEO based in austria. the CFTC is not charging them for dealing with US securities/markets. they are charging them for unlawful retail commodity transactions (illegal swaps), failure to register and failure to implement AML procedures:
On the same day, the CFTC filed a civil enforcement action against 1pool Ltd. and Brunner, stating:
The CFTC’s complaint charges the defendants with engaging in unlawful retail commodity transactions, failing to register as a Futures Commission Merchant (FCM), and supervisory violations for failing to implement procedures to prevent money laundering as required under federal laws and regulations.
