US gasoline stocks fell last week by 150,000 barrels, compared with analysts' expectations in a Reuters poll for a 538,000 barrel-drop. A large drop in crude stocks however boosted the market. US gasoline demand over the past 4 weeks was 9.25 million barrels per day, down 2.4 percent from a year ago, the data showed. Gasoline exports from Europe to the US East Coast were limited to term volumes and uncertainty over demand in the key consumer country limited the arbitrage, traders said. Planned refinery turnarounds in France, Italy, Israel, Spain, Poland, and Hungary were helping to keep supplies of oil product in check, traders said. This comes amid relatively weak arbitrage economics to other regions. Trading houses Vitol and Trafigura are shipping naphtha from the US Gulf Coast and Venezuela to Europe in a rare arbitrage that is a result of weak demand in Asia and lower demand in the US East Coast, traders said.
