LONDON Jan 29 (Reuters) - Diesel barge differentials in northwest Europe rose slightly on Wednesday after data from the United States showed that distillates stocks had fallen by twice as much as expected after cold weather gripped the country.
The Energy Information Administration said stocks on the U.S. East Coast had fallen to their lowest level since April 2008.
Traders and analysts said that heating oil shortages on the East Coast due to the prolonged spell of severely cold weather could trigger more shipments of gasoil and kerosene from Europe, supporting prices.
Several shipments have already made the trip after the arbitrage to the United States opened. "Vessels were being diverted to the United States because the HOGO spread was so wide," a broker said.
The HOGO , which has been at multi-year highs, is the difference between the front month U.S heating oil futures contract and ICE gasoil futures.
A trader added that the backwardation in U.S. heating oil futures was making it difficult to lock in the best prices. "It's very tight there, but it's difficult to capture as people are running hand to mouth," he said.
In the Mediterranean market a trader said that demand from Turkey had slowed this week but it was unclear if this was linked to currency depreciation and the broader turmoil hitting emerging markets with large current account deficits.
"Demand is down and production is generally up so the market seems long on the front," he said.
