The CME Group raised U.S. crude oil futures margins by 25 percent as of the close of business on May 10, helping to bring prices down following a $5 a barrel spike on Monday. CME [CME.O 295.01 3.42 (+1.17%)], parent of the Chicago Board of Trade, said on its website that it had hiked margins for crude oil futures on the New York Mercantile Exchange by $1,250 per contract. With open interest in the contract topping 1.65 million lots last week, that would amount to an over $2 billion increase in total. http://www.cnbc.com/id/42966436 I wonder if this will help my long dollar position
You're assuming that all of those positions are "outright". The actual "margin intake" is a lot less because of spread and hedge positions.
