Crude oil is sliding again.

On Wednesday afternoon in New York, West Texas Intermediate crude futures fell nearly 2% to as low as $44.91 a barrel.

This is the first time WTI has broken $45 since March.

Earlier on Wednesday, the Energy Information Administration released its weekly data on oil inventories, which showed that commercial crude inventories fell by 4.4 million barrels to 455.3 million last week.

An epic buildup in inventories from January through May added to evidence that prices have been pressured by a supply glut from the shale boom.

Concerns about oversupply in the market have sent oil prices even lower in recent weeks, following the 50% crash of last year.

Coupled with weakening demand from China, crude oil has declined with other commodities in a magnitude not seen since 2008.
