Natural gas and weather are the most important drivers. When it's warmer, we don't see that much substitution and natural gas has less influence on heating oil. Stocks aren't that tight.

I expect both the UN and Iran not to want a confrontation and therefore we don't get any clear decision on any action toward Iran at Monday's meeting at the IAEA. OPEC will keep their quotas unchanged at Wednesday's meeting due to the high crude prices.

The inventory levels for crude in the U.S. are quite high, but everybody is concerned about gasoline ahead of the driving season. It looks like prices should go down but then you have the geopolitical issues coming up.

The market is nervous already because Iran is coming more into the picture with the talks with Russia next week. Now with Nigeria, the risks are getting higher. If we see any disruptions to oil production, prices could easily go back up.

The main concern to Iran's reaction isn't the U.S., but that Israel could decide to bomb the nuclear plant. Stability in the area depends on who's in charge in Israel.
