NEW YORK (MarketWatch) -- In order to address recent market volatility, the Chicago Mercantile Exchange has increased its margin requirements on a number of futures contracts, including both its spot yen contracts and yen cross currency contracts. http://www.marketwatch.com/news/sto...x?guid={1972FA50-87EE-448D-BEA1-E80C636F16A0}
Besides the current turmoil, that's "fantastic" news for hedge funds abusing the carry trade. The margin call might just have come a bit closer for a big chunk of speculative capital.
