Currency speculators raised their bets in favour of the US dollar in the latest week to the highest since June 2010, according to data from the Commodity Futures Trading Commission released on Friday. The value of the dollar's net long position rose to $18.04 billion in the week ended November 29, the highest level since the week ended June 8, 2010. In the previous week, long dollar bets stood at $12.11 billion.
Speculators increased their bets against the euro to 104,302 contracts in the latest week from 85,068 contracts a week earlier. Worries that the debt crisis is threatening Europe's core economies have weighed heavily, pushing the single euro zone currency to its lowest in more than seven weeks on November 25.
Short positions in the Swiss franc jumped further to 9,327 contracts, the highest level since May 2007. Speculation has grown in recent weeks that the Swiss National Bank may take further measures, such as increasing the floor on the euro/Swiss franc exchange rate, to weaken its currency. Bets against the British pound rose to 46,660, the highest in a month, the data showed.
To be short a currency is to bet it will decline in value, while being long is a view its value will rise. The Reuters calculation for the aggregate US dollar position is derived from net positions of International Monetary Market speculators in the yen, euro, British pound, Swiss franc, Canadian and Australian dollars.
