Hard to say what really is the main cause and how long it will last. The demand for oil is expected to decline in the later half of this year, therefore lowering inflation expectations. Another thing is, a news item that Japan may take steps to boost the U.S. dollar because the Yen is getting quite high. Also, I think gold has had a great run and is soon due for a correction, it should consolidate for awhile and then resume its uptrend.
