Here are Goldman Sachs comments on the shape of the forward curve in the WTI vs. the Brent. Have seen WTI at a 1.00 discount to Brent last week. Yesterday it narrowed in to -60 cents. With April Brent expiring this week, probably will not come back par again. The May contracts are normal (i.e. WTi at a premium).

We believe that the especially large surplus in the US Mid-Continent explains why WTI has modestly traded through full carry. In contrast, crudes that are not subject to specific issues associated with a landlocked delivery point such as Brent are trading in line with full carry (see Exhibits 4 and 5).
In general, inventories outside of the United States are less amply supplied, which is reflected in much flatter Brent and Dubai crude oil forward curves (see Exhibits 6 and 7). The oversupply in the United States relative to the rest of the world is so extreme that front-month Brent is now trading at a modest premium to WTI, the reverse of the normal relationship.

elsewhere have declined
Going forward, we continue to believe that robust oil demand growth consistent with further expected expansion in the global economy will likely push the global oil market into deficit this year, which should begin to reduce the relatively high level of oil inventories concentrated in the US market (see Exhibit

.
We expect these inventory draws to generate upward price pressure on near-dated prices that should lessen the contango in the crude oil forward curve. In addition, given the current economic outlook, speculative long positions in the oil markets according to the Commodity Futures Trading Commission (CFTC) are substantially smaller than what would be expected (see Exhibits 9 and 10). As a result, the potential extension of investor length commensurate with growth prospects has the potential to generate upward price pressure in the oil complex. Accordingly, we continue to believe that WTI crude oil prices should move above $70/bbl by yearend and maintain our 10% energy total returns forecast as well as our recommendation for an overweight allocation to energy.
