The price gap between benchmark European Brent crude oil and Nymex crude, which has fallen below $5/barrel to reach the smallest levels in 2 years, could for a short while get even narrower as new pipelines send landlocked crude to the Gulf Coast, says Goldman Sachs. 
But it warns a still-narrower spread could be short-lived if supplies start building up there as opposed to instead of Cushing , Okla. , which has long been the source of bottlenecks. That has kept Nymex crude, which is priced there, at a noted discount to Brent.
