WTI is down by 0.21% to $65.37 today

The surprise inventory build from the private data report earlier in the day is weighing on prices, although there's also Middle East tensions to consider in the picture for the time being that may be supportive for oil.
Syria may not be a key oil exporter in the region, but in general any sort of Middle East tensions tend to have some spillover effect to the oil market. Then, there's also the case of US and Iran to weighing on top of that as well - with the 12 May deadline drawing closer by the day.
From a technical standpoint, a break of the $64.24 level highlighted yesterday clears the way for a retest of the year's high at $66.66.
Currently on the agenda all we have is the EIA report due at 1430 GMT later, so that's the key risk event to look out for that could sway prices to/away from a test of the year's high.
