Correlation between crude oil, Brent oil and heating oil edged down as Brent oil and heating oil faced additional pressure from worries over the European debt crisis. Crude oil's link with natural gas dropped essentially as US inventories blocked any stimulus for natural gas price increase. Interdependence between crude oil and Standard and Poor's SP500 (SPX) eased down after positive headlines from China and the EU. Meanwhile, crude oil's tie with the pair EUR/USD moved up to 0.2 as crude oil and the Euro positively responded to improved ZEW sentiment in Germany.
