Analysis: Even a broken Brent benchmark is the best for now

Goldman Sachs (GS.N) says Brent is still undoubtedly the best crude oil benchmark and that diminishing physical volume is not an issue.
"It does not matter. Physical and paper are two different things," said Jeff Currie, global head of commodities research at Goldman Sachs, one of the most influential banks in the commodities market.
Compared with Brent, he described U.S. crude, also known as West Texas Intermediate (WTI), as "idiosyncratic" because of storage issues at Cushing, Oklahoma, the delivery point for U.S. futures, where inventories hit record levels last year.
Even assuming weakness in U.S. futures, strength in Brent futures since the start of this year has been remarkable.
"It (Brent) is definitely not perfect. But still, compared to the others that we live with -- WTI and the Asian benchmarks, which are even worse in a way -- it is clearly the best one we have," said David Wech, head of research at JBC Energy in Vienna.
Its importance has grown as new oil streams have adopted it as a benchmark.
"From Australia to Latin America, Brent is the chosen benchmark. It has proven to be the most reliable," said Wech.
FLAWED BUT VALUABLE
A benchmark, even if flawed, is essential because it is not possible to agree an outright price for every oil sale.
"For all the oil that is sold, much of it is typically on some sort of term contract, and for that you need a price basis. A benchmark fulfils that need," said Wech.
Light sweet benchmarks have been favored as they reflect the kind of crude any refinery can process. Any shift toward heavier and more sulfurous crude would be gradual as refineries grow more sophisticated and the international balance of oil production shifts.
2/ Brent futures this month leapt to a more than $9 premium per barrel over lighter and better quality WTI, which historically has traded at a premium to Brent.
They coincide with increased investment fund flows following this month's re-weighting of commodity indexes toward Brent futures and away from U.S. crude.
2/ Jorge Montepeque, a director at Platts, has not ruled out bolting on more crudes to the BFOE benchmark but said an adjustment to the futures contract, rather than adding more physical grades, could be the answer.
The Brent mechanism "was less than optimum", he said. Because of a time lag between the physical and futures markets, only 70-75 percent of Brent physical crudes are available for delivery against ICE Brent.
