So do I understand you correctly that the US market is not enforcing position limits but overseas markets are ?
Also, that it’s only US-based funds (pension, IBs, hedges whatever) that don’t get classified as specs and not other “funds” like SWFs and other overseas entities ?
This situation is unique to the US. I don't know if any hedge funds are using investment banks in this fashion. I don't **think** so, because we should have heard about it by now if they were.
The US exchange are certainly enforcing position limits -- the point here is that the biggest specs are in a situation where they are not subject to the limits. This simply has to be stopped.
Legitimate industry hedgers, aka 'commercials', should continue to be exempt from position limits, of course.
